Dear Mr. Macomber:
Enclosed is the Office of the Inspector General’s (the OIG) report titled Special Review of the
California Department of Corrections and Rehabilitation’s Response to Incarcerated-Person-on-
Incarcerated-Person Allegations Under the Prison Rape Elimination Act. California Penal Code section
6126, subdivisions (b) and (c) authorize the OIG to initiate reviews of the California Department
of Corrections and Rehabilitation’s (the department) policies, practices, and procedures. In
this review, we assessed departmental responses to 74 of 288 (26 percent) alleged violations of
the Prison Rape Elimination Act (PREA) that were investigated and closed from March 2024
through August 2024. The 74 cases we reviewed were reviewed by prison Institutional PREA
Review Committees (review committees) from March 1, 2024, through August 31, 2024. While
violations of PREA may be alleged against prison employees, this special review assessed only the
department’s investigation of allegations made against incarcerated people.
During our assessment, we reviewed departmental responses to PREA allegations at three
different stages: identification, investigation, and institutional oversight and review. We broadly
assessed whether prison staff and management properly identified and initiated required
protocols in response to PREA allegations, whether the investigations were timely and in
compliance with department policy, and whether prisons adequately conducted incident reviews
in compliance with departmental policy.
We found several concerning issues in the department’s handling of the PREA allegations and
investigations we reviewed. Prison staff and supervisors did not always complete required duties
when they were notified of PREA allegations, and alleged victims were not always offered medical
or mental health treatment, including forensic examinations to collect and preserve physical
evidence. Furthermore, departmental staff did not always offer alleged victims support persons or
advocates as required by departmental policy.
In addition, almost all the investigations of PREA allegations we reviewed were inadequate for
one or more reasons. We found that investigators did not perform one or more investigative
procedures in 91 percent (67 of 74) of the cases we reviewed. In some cases, investigators did not
collect sufficient evidence or interview alleged victims, alleged suspects, or potential witnesses.
We also found that some of the investigative reports we reviewed lacked basic facts and contained

errors and inconsistencies. Moreover, some investigators had not received required specialized
PREA training as required by law and departmental policy.
In nearly all incidents we reviewed, we found significant inadequacies that review committees
missed or failed to address. Consequently, we found that review committees did not provide
proper oversight to ensure PREA investigations were adequate and complete. By failing in
their oversight role, review committees generally did not ensure departmental staff followed
either federal and state law, or departmental policy and guidelines when responding to
PREA allegations.
Following publication, we request the department provide its status on implementing our
recommendations at intervals of 60 days, six months, and one year from the special review
report date.
Respectfully submitted,
Amarik K. Singh

PREA Allegations, Special Review, August 2025 | 1
Introduction
California Penal Code section 6126(b) authorizes the Office of the
Inspector General (the OIG) to initiate a review of the California
Department of Correction’s (the department) policies, practices, and
procedures. In this review, we assessed departmental responses to 74 of
288 (26 percent) alleged violations of the Prison Rape Elimination Act
(PREA) that were investigated and closed from March 2024 through
August 2024. The 74 cases we reviewed were reviewed by the prison
Institutional PREA Review Committees (review committee or IPRC)
from March 1, 2024, through August 31, 2024.1 While violations of
PREA may be alleged against prison employees, during this review we
assessed only the department’s investigation of allegations made against
incarcerated people.
During our assessment, we reviewed departmental responses to PREA
allegations at three different stages: identification, investigation,
and institutional oversight and review. We broadly assessed whether
prison staff and management properly identified and initiated required
protocols in response to PREA allegations, whether the investigations
were timely and in compliance with departmental policy, and whether
prisons adequately conducted incident reviews in compliance with
departmental policy. To accomplish this, we reviewed PREA case
documentation, met with prison staff, and analyzed the results of PREA
investigations. We also attended review committee meetings to assess
whether departmental staff complied with regulations, procedure, and
applicable laws.
Background
“It is the policy of the CDCR [the department] to provide a safe, humane, secure
environment, free from sexual misconduct. CDCR shall maintain a zero tolerance for
sexual misconduct in its institutions, community correctional facilities, conservation
camps, and for all offenders under its jurisdiction. Sexual misconduct between
offenders and by staff towards offenders is strictly prohibited.
Source: Departmental policy memorandum dated November 2, 2006, titled “Prison
Rape Elimination Act – Zero Tolerance Policy.”
1. Each prison is required to conduct an incident review of every sexual violence allegation,
including allegations that have not been substantiated. An incident review is not required
for allegations that have been determined to be unfounded. Only two investigations
we reviewed that went to IPRC were determined to be unfounded, but 48 allegations
determined to be unfounded were closed during our review period. Therefore, our case
review was not inclusive of all unfounded investigation outcomes, and it is likely most
allegations determined to be unfounded are not reviewed by IPRCs.

2 | PREA Allegations, Special Review, August 2025
Prison rape and other forms of sexual misconduct including unwanted
touching and verbal harassment, have historically been problems
affecting the safety and security of incarcerated populations in America’s
prisons, including those in California. To combat rape in prisons
nationwide, Congress enacted the Prison Rape Elimination Act (PREA)
in 2003.2 This historic legislation established a “zero tolerance” standard
for rape in prisons in the United States.3
PREA also created the National Prison Rape Elimination Commission
which drafted national standards for eliminating prison rape.4 The
Department of Justice published the final PREA Standards in the Federal
Register on June 20, 2012, and they became effective August 20, 2012.5
Under federal law, a state whose Governor does not certify full
compliance with the standards is subject to the loss of five percent of
any Department of Justice grant funds that it would otherwise receive
for prison purposes, unless the Governor submits an assurance that the
five percent will be used only for the purpose of enabling the State to
achieve and certify full compliance with the standards in future years.6 In
addition, any correctional accreditation organization that seeks Federal
grants must adopt accreditation standards regarding sexual abuse that
are consistent with the national standards.7
PREA standards require the department to have written policies
mandating zero tolerance toward all forms of sexual abuse and
harassment and outlining its approach to preventing, detecting, and
responding to such conduct.8 The executive summary of the federal rules
emphasized that the success of the PREA standards in combating sexual
abuse in prisons depended on effective leadership but acknowledged
that effective leadership could not be directly mandated. Instead, the
federal standards were intended to foster a change in prison culture
by institutionalizing policies and practices that were generally not
outcome-based but rather focused on policies and procedures to reduce
and ameliorate bad outcomes. Furthermore, while the standards were
intended to include a variety of best practices, they did not incorporate
every avenue of combating sexual abuse.9 The federal act is the
foundation of the department’s response to PREA allegations and its
zero-tolerance policy for sexual misconduct in California prisons.10

The Sexual Abuse in Detention Elimination Act of 2005 is also
foundational to combating sexual misconduct in California prisons.11
Like PREA, the Sexual Abuse in Detention Elimination Act requires the
department to ensure that its protocols for responding to sexual abuse
include providing the safest possible housing options to incarcerated
people who experience repeated abuse,12 implement thoughtful,
confidential standards of physical and mental health care to reduce the
impact of sexual abuse,13 and ensure specific procedures are performed
in the investigation and prosecution of sexual abuse incidents.14
Consequently, the department established policy and procedures and
required all staff to receive training related to the prevention, detection,
response, and investigation of sexual misconduct in California prisons.15
Sexual misconduct can include three different forms of abuse that
are specifically prohibited by PREA standards and departmental
policy: nonconsensual sexual acts, abusive sexual contact, and sexual
harassment.16 Under PREA standards and departmental policy,
nonconsensual sexual acts are generally defined as unwilling or forced
sexual contact or penetration, such as rape.17 Abusive sexual contact is
generally defined as unwanted touching directly or through the clothing
of the genitalia or other intimate parts of a person in a sexual manner.18
Finally, sexual harassment is generally defined as unwelcome conduct that
does not involve physical contact, such as unwanted sexual advances.19
Collectively, we refer to any claims of sexual misconduct as PREA
allegations in this report. While PREA allegations can be made against
prison employees, as we explained in the introduction, this report
assesses only the department’s response to allegations made against
incarcerated people in State prisons.
The OIG plays an important role in combating sexual violence in
California prisons because it has the authority to receive confidential
letters regarding sexual abuse, inspect institutions and interview all
incarcerated people, and investigate reports of the mishandling of
incidents of sexual abuse.20 The OIG forwards allegations of rape
and sexual assault made against staff and incarcerated people to the
department for review. In 2024, the OIG referred 538 PREA allegations
against staff and incarcerated people to the department for processing.

4 | PREA Allegations, Special Review, August 2025
Reporting a PREA Allegation
The first steps prison staff take when responding to PREA allegations are
critical to preserving evidence and facilitating thorough investigations,
and PREA standards require that the department provide multiple ways
for incarcerated people to report PREA allegations.21 A victim may report
a PREA allegation by informing departmental staff verbally or in writing;
utilizing the incarcerated person appeals process; utilizing departmental
or OIG sexual assault hotlines; or informing a third party who in turn
reports the allegation to the department or the OIG.22 Departmental staff
must immediately and confidentially report PREA allegations to the
appropriate supervisors when they become aware of them.23 In addition,
departmental staff must complete an incident report if they witness a
suspected PREA violation or receive a PREA allegation.24
Staff who initially respond to the PREA allegation must take the alleged
victim to a private, secure location and request they not shower, remove
clothing without custody supervision, use restroom facilities, or consume
any liquids.25 In addition, staff are required to refer alleged victims for
medical or mental health evaluations.26
Custody supervisors have significant responsibilities when they
are notified of PREA allegations. Custody supervisors must assign
alleged victims a custody escort who will remain with the alleged
victims throughout the medical exam process, whenever possible.27
Custody supervisors must also ensure that purported crime scenes are
secured and ensure a log of all persons entering the crime scene area
is maintained.28 Finally, custody supervisors must arrange housing
alternatives for the alleged victims and consider their risk of sexual
victimization while assessing appropriate housing placement.29 To assist
custody supervisors with responding to PREA allegations, departmental
training and guidelines include a checklist identifying all actions they are
required to complete.30

PREA Allegations, Special Review, August 2025 | 5
Investigations of PREA Allegations Committed by
Incarcerated Offenders
PREA standards require the department to have a policy in place
governing the conduct of investigations and ensure that a prompt,
thorough, and objective investigation is completed for all allegations of
sexual abuse and sexual harassment occurring in its prisons.31 To do this,
prison authorities assign locally designated investigators (investigators)
who are specifically trained to investigate PREA allegations.32
Departmental policy and training mandates that investigators use
standard fact-finding techniques including interviewing alleged
victims, suspects, and potential witnesses.33 Investigators should record
interviews when possible and objectively assess the reliability of victims,
suspects, and witnesses on an individual basis.34 Investigators should
also review available evidence from the audio-video surveillance system
and departmental records, such as movement logs and phone calls.35
Investigators may collect evidence from crime scenes, as well as from
alleged victims’ and suspects’ clothing and bodies.36 Finally, departmental
staff log and store any physical evidence specialized nurses collect during
forensic medical examinations.37
The department has established guidelines for investigators to follow
while questioning PREA victims about the specific details of their
allegations. In part because of the sensitive nature of the allegations,
alleged victims have a right to an advocate and a support person of
their choosing present during their forensic medical examinations and
investigatory interviews.38 However, support people may be excluded
from the forensic medical examinations or investigatory interviews if
their presence would be detrimental.39 The department or a medical
provider excluding a support person or advocate from a forensic medical
examination must document their reasons for doing so.40 Likewise, the
investigator or district attorney excluding a support person from

investigatory interviews must document their reasons, but they must also
notify alleged victims about the exclusion prior to the interview.41
The time frame of when an incarcerated person reports a PREA
allegation affects the steps investigators take when collecting and
processing evidence. Custody supervisors are required to secure alleged
victims, named suspects, and crime scenes, if feasible, for forensic
processing.42 Custody supervisors must also transport suspects and
willing victims to forensic medical examinations if the alleged incident
occurred less than 72 hours before it was reported and involved
nonconsensual sex acts.43 When a PREA allegation involves abusive
sexual contact, such as unwanted touching, prison staff must generally
consult with a specialized nurse to determine if a forensic medical
examination is warranted.44

PREA Allegations, Special Review, August 2025 | 7
When completing investigations of alleged PREA violations,
investigators reach one of three conclusions using a “preponderance of
the evidence” standard: substantiated, unsubstantiated, or unfounded.47
Investigators conclude an allegation is substantiated if they determine
the alleged violation occurred, while a conclusion of unfounded
means investigators determined the alleged violation did not occur.48
If investigators cannot determine whether an alleged PREA violation
occurred, it is deemed unsubstantiated.49 Generally, investigations
without any independent witnesses or other evidence (video footage,
forensic medical examinations, etc.) result in determinations that the
allegations are unsubstantiated, even if an alleged victim reported in
detail that the incident occurred.
Figure 1 below explains the three outcomes that can result from an
investigation.

based on the more convincing evidence and its probable truth or accuracy, and not in the

8 | PREA Allegations, Special Review, August 2025
The Institutional PREA Review Committee Incident Review Process
PREA standards require prisons to conduct incident reviews at the
conclusion of every sexual abuse investigation, including where the
allegations have not been substantiated.50 To accomplish this, the
prison’s PREA compliance manager schedules PREA allegations for
review by the prison’s review committee within 60 days of the date
of discovery of the allegation, or within 30 days of closure of the
investigation, whichever is sooner.51 While incident reviews are not
required if investigators determine PREA allegations to be unfounded,
wardens may nevertheless request the case be reviewed.52
Review committees are normally composed of the prison’s warden or a
designee, and a variety of custody and medical staff.53 Generally, review
committees are responsible for considering whether the allegation or
investigation indicates a need to change policy or practice to better
prevent, detect, and respond to sexual abuse.54
Figure 2 below outlines roles and responsibilities of the
review committee.
Figure 2. Roles and Responsibilities of the Institutional PREA Review Committee
The Institutional PREA Review Committee shall:
• Consider whether the allegation or investigation indicates a need to change policy or
practice to better prevent, detect, or respond to sexual abuse.
• Consider whether the incident or allegation was motivated by race; ethnicity; gender
identity; lesbian, gay, bisexual, transgender, or intersex identification, status, or perceived
status; or gang affiliation; or was motivated or otherwise caused by other group dynamics
at the facility.
• Examine the area in the facility where the incident allegedly occurred to assess whether
physical barriers in the area may enable abuse.

PREA Allegations, Special Review, August 2025 | 9
Review committees generally oversee PREA allegations from initial
reporting through the conclusion of the investigations. As part of the
review process, the committees must judge whether staff’s actions prior
to, during, and subsequent to the reporting of the allegation were in
compliance with regulations, departmental procedure, and applicable
law.55 Review committees must also determine if follow-up action is
necessary and consider changes to policies and procedures to better
prevent, detect, and respond to sexual misconduct in the prisons.56
Sexual Abuse and Misconduct Statistics in California Prisons
The department has a zero-tolerance policy for sexual misconduct
in its prisons and is committed to providing a safe, humane, secure
environment, free from sexual violence and sexual harassment.
Nevertheless, allegations of sexual misconduct are still common in
departmental facilities.
Since 2018, the department reports having received over 3,000 PREA
allegations made against incarcerated people. As reported by the
department, Tables 2 through 4 on the next page provide a six-year
summary of PREA allegations made against incarcerated people by
allegation type, and the outcome of departmental investigations into the
allegations.
The OIG analyzed 74 PREA allegations reviewed by prison review
committees from March 1, 2024, through August 31, 2024. Figure 3 on
page 11 provides a breakdown of the 74 PREA allegations we analyzed in
this special review. Of the cases we reviewed, 46 alleged nonconsensual
sex acts, 26 alleged abusive sexual contact, and two alleged sexual
harassment.

Review Results
We found several concerning issues in the department’s handling of
the PREA allegations and investigations we reviewed. Prison staff did
not always appropriately report or document PREA allegations when
they were initially received, and alleged victims were not always offered
medical or mental health treatment. In addition, we found investigators
did not perform one or more investigative procedures in all but six cases
we reviewed. In some cases, investigators did not: collect sufficient
evidence; interview alleged victims, suspects, or potential witnesses; or
review available audio-video surveillance system footage. Investigators
also did not always video or audio record interviews with alleged victims
or suspects. The department also failed to offer alleged victims a support
person or advocate as required by departmental policy. Moreover, some
investigators had not received required specialized PREA training.
We found that review committees missed or failed to address any of
the inadequacies that we identified in 67 out of the 74 (91 percent)
investigations we analyzed. Review committees did not provide proper
oversight to ensure PREA investigations were adequate and complete. By
failing in their oversight role, review committees generally did not ensure
departmental staff followed either federal and state law, or departmental
policy and guidelines when responding to PREA allegations.
Investigators substantiated 9 percent (7 of 74) of the PREA allegations we
reviewed, meaning they determined the allegations were more likely than
not to have occurred based on a preponderance of the evidence. However,
investigators overwhelmingly determined there was insufficient evidence
to make a final determination as to whether the majority of PREA
allegations made occurred, finding 88 percent (65 of 74) of the allegations
to be unsubstantiated, and three percent (2 of 74) of the allegations to
be unfounded. Figure 4 below shows the type of allegations and the
investigation outcomes for the 74 incidents we reviewed.

March 1, 2024, through August 31, 2024.
Figure 5 on the next page further details that 43 percent (32 of 74) of the
PREA allegations we reviewed were reported less than 72 hours after the
incidents, while 57 percent (42 of 74) were reported over 72 hours after
the alleged incidents. The oldest, a case involving alleged nonconsensual
acts, was reported 19.5 years after the alleged incident occurred. In
general, it is more difficult for the department to thoroughly investigate
and reach supportable determinations on PREA allegations made more
than 72 hours after the incident reportedly occurred.

Chapter 1. Prison Staff Did Not Always
Perform Required Procedures When Notified of
PREA Allegations
We found that prison staff generally recognized and responded when
an incarcerated person or third party reported PREA allegations.
However, in three percent (2 of 74) of incidents we reviewed, the alleged
victims stated they had previously reported their PREA allegations to
departmental mental health or medical staff. Although investigators were
assigned to the allegations, none determined whether the incarcerated
people had previously reported these incidents or, if they had, why the
allegations had not been investigated.
Prison staff also incorrectly classified the PREA allegations in two cases
we reviewed. In the first incident, investigators incorrectly classified an
allegation that the PREA suspect allegedly digitally penetrated the victim
as abusive sexual contact, which does not involve penetration, instead
of a nonconsensual sex act, which does. The investigative report only
included information related to unwanted touching and did not contain
any information on the alleged digital penetration. Consequently, the
investigator may not have addressed the allegation at all. In addition,
the specialized nurse making the determination on whether a forensic
examination was warranted may not have known that the victim alleged
he was digitally penetrated. Ultimately, the specialized nurse did not
recommend the alleged victim receive a forensic examination. In the
second incident, prison staff incorrectly classified an allegation that an
incarcerated person climbed on top of another incarcerated person and
asked for sexual favors as sexual harassment instead of abusive sexual
contact, a more severe form of sexual misconduct.
Staff and Supervisors Did Not Always Complete Required Duties
When They Were Notified of PREA Allegations
To assist staff in fulfilling their responsibilities under law and policy, the
department created a PREA initial contact guide57 and trained staff58 to
implement specific procedures upon receipt of a PREA allegation.59 It
is critical that staff follow departmental guidance because many of the
instructions contained in the PREA initial contact guide are intended
to preserve physical evidence in compliance with law and departmental
policy.60 For example, staff are required to request that a PREA victim not
shower, use the restroom, consume liquids, or remove clothing without

custody supervision, to preserve potential evidence for forensic
medical examinations.61
However, in the cases we reviewed, we found documentation that staff
had taken steps to preserve physical evidence in only 21 percent (four
of 19) of incidents alleging nonconsensual sex acts that were reported
within 72 hours. Therefore, even if the allegations of nonconsensual
sex acts were timely reported and investigated, the probability that
physical evidence would have been recovered during forensic medical
examinations was likely reduced.
We recognize that the procedures detailed in the PREA initial contact
guide may not be warranted or necessary to preserve evidence of
allegations of nonconsensual acts reported long after the incident. The
instructions may also not be warranted or necessary in allegations of
abusive sexual contact or harassment. However, unless staff document
that they followed—or document why they did not follow—the
procedures outlined in the PREA initial contact guide, management
cannot determine if staff followed departmental policy intended to
preserve critical physical evidence.
The department created procedures for custody supervisors to follow
upon receipt of PREA allegations and trained the supervisors on the
procedures.62 These procedures are intended to, among other things,
preserve physical evidence during investigations. However, as was the
case with the PREA initial contact guide, we found that supervisors did
not always follow the steps outlined in the custody supervisor checklist.
For example, custody supervisors did not document taking any measures
to secure crime scenes63 in 42 percent (eight of 19) of nonconsensual sex
act allegations we reviewed that were reported less than 72 hours after
the incident.
In addition to securing crime scenes, the custody supervisor checklist
itemizes many other steps supervisors must take in response to PREA
allegations. We analyzed the documentation in the 74 incidents we
reviewed to determine if either custody supervisors or investigators took
necessary steps to comply with departmental policy, even if a completed
checklist was in the case file. Table 5 below illustrates the number of
violations of select itemized policy requirements we found on the custody
supervisor checklist.

Like the instructions contained in the PREA initial contact guide,
the steps itemized in the custody supervisor checklist are critical to
both preserve evidence and ensure PREA investigations are complete
and thorough.64 Therefore, unless staff document that they completed
the required steps, management cannot verify compliance with
departmental policy.
Staff Did Not Always Ensure Alleged PREA Victims Received
Required Mental Health or Medical Evaluations, Including
Forensic Examinations
As we explained above, departmental staff are required to preserve
physical evidence when responding to PREA allegations, particularly
when the incident is alleged to have occurred less than 72 hours before
it was reported.65 Consequently, unless the incarcerated person alleged
only harassment, departmental policy requires staff to either transport
suspects and willing victims for forensic medical examinations66 or
consult with a specialized nurse to determine if an examination is
warranted.67 We found that staff generally complied with policy but failed
to do so in 19 percent (six of 32) of incidents alleged to have occurred less
than 72 hours before they were reported.
In one incident, an incarcerated person alleged he was forced to
perform nonconsensual sex acts and reported it the same day. However,
an investigator closed his investigation approximately 24 hours later,
“. . . due to the time lapse in the date of the allegation and the date
the alleged incident was reported.” We did not find any information
in the PREA case record or the investigative report that supported
the investigator’s conclusion. Therefore, the investigative report was
inaccurate—a problem we discuss in greater detail later in this report—
and the alleged victim was not transported for a forensic medical
examination as required by departmental policy.
The remaining five incidents reported less than 72 hours after the PREA
violations allegedly occurred involved allegations of abusive sexual
contact. Staff did not consult with a specialized nurse to determine if a
forensic medical examination was necessary in three of those cases as
departmental policy requires, and we could not determine if staff did so
in the other two cases.
Even if a PREA violation is reported more than 72 hours after the
incident allegedly occurred, staff are required to consult with a
specialized nurse to determine if a forensic medical examination is

warranted unless the incident involved only harassment.68 However, we
found that staff failed to consult with a specialized nurse in 50 percent
(21 of 42) of the allegations reported more than 72 hours after the incident
allegedly occurred. Of those incidents, 13 alleged nonconsensual sex acts
and eight alleged abusive sexual contact.
Investigators often made the decision not to contact a specialized
nurse based on the amount of time that had passed between the alleged
incident and the date the PREA allegation was reported. For example,
when allegations were reported weeks, months, or years after the
incident, investigators did not consult with a specialized nurse. However,
the responsibility of making those determinations rests with trained
medical professionals under departmental policy.69
In addition to forensic medical examinations, PREA standards and
departmental policy require staff to refer alleged victims for medical
and mental health evaluations.70 We found that the department met this
requirement in nearly all cases we reviewed. However, alleged victims did
not immediately receive a medical evaluation or mental health referral in
seven incidents we reviewed. The delays ranged between two and eight
days after the incidents were reported.
Departmental Staff Did Not Offer Alleged PREA Victims a Victim-
Support Person or a Victim Advocate in Nearly Half the Cases
We Reviewed
Incarcerated people, like all victims of sexual assault or other
misconduct, suffer significant trauma and may need support to guide
them through the investigatory process. To assist alleged PREA victims
in prisons, the law generally and departmental policy give victims the
right to the assistance of both a support person of their choosing and a
professional victim advocate who is specially trained to assist victims
of sexual assault.71 Victim advocates reduce survivors’ trauma in the
following ways:
• Advocates increase survivors’ wellness and help them cope
with the trauma of sexual abuse.
• Survivors are likely to feel more comfortable with the
investigation if they have an advocate.
• Survivors who feel comfortable and supported are more
likely to participate in the investigative process, which
increases the likelihood of a successful investigation.

In violation of departmental policy, custody staff offered a victim support
person or advocate in only 43 of the 74 PREA incidents (58 percent) we
reviewed. In addition, in three cases, investigators did not offer alleged
victims the services of a support person or advocate until after they
were interviewed, even though one of the purposes of a victim support
person and advocate is to assist and support victims during the interview
process. By not offering a support person or advocate, victims may be
less forthcoming or willing to participate in PREA investigations.

Chapter 2. Almost All Investigations of PREA
Allegations We Reviewed Were Inadequate for
One or More Reasons
Overall, we found one or more deficiencies in 67 of the 74 PREA
investigations we reviewed (91 percent), including: investigators failing
to conduct interviews or conducting inadequate interviews; investigators
failing to secure, collect, or consider evidence; and investigators
submitting poorly written investigative reports. We also found eight
PREA investigations were not conducted by an investigator specifically
trained to conduct PREA investigations, as required by standards and
departmental policy.72
Investigators Did Not Conduct Timely Interviews, or Did Not Conduct
Interviews at All
Investigators must conduct thorough interviews once they identify
alleged PREA victims, PREA suspects, and potential witnesses.73
However, in three incidents we reviewed, investigators assigned to
conduct investigations at the prisons where the incidents allegedly
occurred did not interview the alleged victims. The investigators
instead relied only on memoranda produced at the prisons where the
incarcerated people were housed when they made the allegations.
Because PREA allegations must be investigated where the incidents
allegedly occurred,74 the memoranda investigators relied on were likely
initial preliminary interviews with the alleged victims. Therefore,
investigators at the prisons where the alleged incidents occurred likely
needed additional evidence to make supportable determinations on the
merits of the allegations.
In addition, investigators did not interview the PREA suspects in 12
of the 74 (16 percent) incidents we reviewed. In 26 cases (35 percent),
investigators made no attempt to identify witnesses and, therefore did
not interview anyone who may have been able to corroborate or refute
the PREA allegations. By not interviewing the alleged victims, those
accused of violating PREA, or potential witnesses, investigators may not
have received all relevant facts and detailed information necessary to
support their determinations.
Investigators conducted untimely interviews in at least seven incidents (9
percent) we reviewed. When notified of a PREA allegation that occurred
at another prison, PREA standards and departmental policy require
prison staff to notify the prison where the incident occurred as soon as
possible, but no later than 72 hours—or three days—after receiving the

allegation.75 However, in one case we reviewed, the prison that received
multiple PREA allegations from one alleged victim did not forward the
complaints to the prison where the incidents occurred until four days
later. To make matters worse, the investigator at the prison where the
incidents allegedly occurred did not interview the alleged victim for
an additional 17 days, took as long as 30 days to interview identified
witnesses, and took 54 days to interview a registered nurse for case
information. Ultimately, the investigator did not complete all interviews
until almost two months after the alleged PREA victim reported
the incidents.
Investigators in six other incidents (8 percent) we reviewed delayed
interviewing alleged victims and suspects between six and 41 days.
The longer it takes to conduct interviews, the less likely it is that
individuals will accurately remember the specific details vital to
PREA investigations.
Investigators Generally Did Not, but Should, Record All Interviews of
Alleged PREA Victims or Suspects
Departmental training instructs investigators to video or audio record
interviews of alleged PREA victims as soon as appropriate.76 The training
particularly emphasizes the importance of conducting victim interviews
and states that recording statements can be an excellent investigative
tool.77 Some of the advantages of recording interviews are to:
• Provide more detail than handwritten notes.
• Enable investigators to be more attentive during
the interview.
• Assist investigators in synopsizing details.
• Protect the interviewer should a complaint or
misunderstanding arise.
• Convey the victim’s immediate response to prosecutors
and jurors.
We believe the department would benefit from recording all interviews,
including those with suspects and witnesses, for the same reasons
emphasized in the departmental training and for the reasons we state
below. It is troubling that investigators did not either video or audio
record any interviews in 70 percent (52 of 74) of the PREA investigations
we reviewed. Investigators video recorded one or more interviews in only
nine cases (12 percent), and audio recorded interviews in only 17 cases
(23 percent).

24 | PREA Allegations, Special Review, August 2025
Although most of the interviews in the PREA investigations we reviewed
were not recorded, the benefits of recording interviews were apparent
when we listened to the few which were. For example, in one incident we
reviewed, an investigator’s report did not document that an alleged PREA
victim made an unrelated PREA allegation during her interview. We
found no evidence the unrelated allegation was reported or investigated.
Similarly, in another incident we reviewed, an alleged PREA victim
stated in a video-recorded interview that he had previously reported
his PREA allegation to a staff psychologist, but the investigator did
not include this information in the investigative report. Consequently,
there was no evidence the investigator attempted to determine if the
allegation had been previously reported, and if it had been, why it was
not investigated. We also identified from the alleged victim’s recorded
interview that he reported a second unrelated PREA allegation to
the investigator. However, we did not find any documentation that
the investigator either reported the second allegation or conducted a
separate investigation of the second PREA allegation.
We were also concerned about an investigator’s conduct during a third
video-recorded interview we reviewed. As the alleged victim began
to explain the details of the abusive sexual contact allegation, the
investigator interrupted the alleged victim several times. We heard
one investigator interrupt the alleged victim, asking, “So you do want
to file a PREA, correct?” As the alleged victim continued to speak, the
investigator interrupted again, “It’s a yes or no” and “We will be out of
here real quick.” Eventually, the investigator appeared to realize he was
being unnecessarily argumentative and changed his tack.
According to departmental policy and training, victims of sexual
misconduct may be seriously traumatized physically and/or mentally;
therefore, staff are expected to be sensitive to alleged victims.78 Many of
the statements made during the interview demonstrated a lack of
consideration and respect toward the alleged PREA victim and escalated,
rather than deescalated, the already tense interview. Investigators may
have also potentially compromised the investigation, admitting to the
alleged PREA suspects that the investigation would not take long
because they did not have enough evidence.
An investigator told one suspect, “[There is] not a lot of evidence for me to
review . . . it’s Tuesday, we’ll be done by the end of the week.” Also, when
speaking with another suspect, the investigator said, “Like I was telling the other
individual out there who was hootin [sic] and hollerin [sic]. . . . these things tend
to go fast, there’s not a lot of evidence to our investigations.”

If they are available and are reviewed, recorded interviews provide
both departmental management and review committees a better tool
to assess and oversee the quality of PREA investigations by identifying
and addressing clear deficiencies in either the investigators’ conclusions
or reporting. Given the clear benefits, the department should require
investigators to record all interviews unless they document a legitimate
reason for not doing so.
Investigators Did Not Always Collect and Secure Potential Physical or
Documentary Evidence
As we stated earlier in this report, investigators determine PREA
allegations to be unsubstantiated if there is insufficient evidence to
establish whether the incident occurred.79 Therefore, it is critical
for investigators to collect and review available evidence in order to
conduct thorough investigations and reach supportable determinations,
as required by law and departmental policy.80 However, we found that
in several incidents we reviewed, investigators determined PREA
allegations to be unsubstantiated without collecting or reviewing
available evidence.
When sexual misconduct occurs, physical or biological evidence may
be present at the crime scene. Custody supervisors are required to
secure crime scene locations to allow investigators to collect potential
evidence.81 As we discussed earlier in this report, of the 19 nonconsensual
sex act allegations that victims reported less than 72 hours after
occurrence, investigators determined most to be unsubstantiated.
However, we found no evidence that anyone secured crime scenes
in eight of the 19 incidents (42 percent), six of which investigators
specifically determined to be unsubstantiated without attempting to
collect evidence from the scenes. Failure to secure the crime scene
could have led to the loss of potential evidence due to contamination or
tampering, and prevented investigators from collecting evidence which
may have substantiated the PREA allegations.
Even when evidence was collected, investigators did not always consider
it before reaching their conclusions. For example, investigators closed
five nonconsensual act investigations before the results of the alleged
victims’ and suspects’ forensic medical examinations were considered.
One investigator closed a case the same day the incident was reported,
before the alleged victim and suspect were even transported to forensic
medical examinations. Another investigator concluded an allegation
was unfounded without reviewing the forensic examination results. In
all five cases, the alleged victims reported the PREA violations either

on the same day or within a day of the alleged misconduct. PREA
investigators are required by law and departmental policy to gather and
preserve all relevant evidence, which should clearly include the results
of forensic medical examinations.82 If investigators do not consider all
evidence, their investigations are not thorough, and neither departmental
management, nor PREA victims and suspects can be assured that the
investigators’ conclusions were supported by an unbiased review of all
available evidence.
In four additional cases we reviewed alleging nonconsensual sex acts,
investigators collected physical evidence including clothing worn by
alleged PREA victims. This is important because, as stated earlier in this
report, biological evidence is more likely to be present in allegations of
nonconsensual sex acts. However, like the forensic medical examination
results we discussed above, we found no documentation that the
collected evidence was tested or considered during the investigations.
In addition, despite failing to test available evidence, investigators
determined there was insufficient evidence to reach a conclusion on the
merits of the PREA allegations.
Investigators may also have access to potentially relevant evidence such
as audio-video surveillance system recordings of the alleged crime scene,
phone records, or mail sent and received by those involved in the PREA
allegation. However, in 28 of the 74 cases (38 percent) we reviewed,
investigators determined the PREA allegations to be unsubstantiated
without making any attempt to identify evidence beyond conducting
interviews. By not pursuing other potential avenues of investigation,
investigators may have missed evidence that could have supported or
refuted the PREA allegations.
Some Investigative Reports Lacked Basic Facts and Contained Errors
and Inconsistencies
Some investigative reports we reviewed lacked documentation of basic
facts or contained errors and inconsistencies. For example, in one case,
an investigator reported he canvassed the facility where the PREA
incident allegedly occurred but was unable to find witnesses with
information relevant to the investigation. However, the investigator did
not describe how he canvassed the facility or document the incarcerated
people or staff he spoke with. In addition, the investigative report
contained errors and inconsistencies in the alleged victim’s and suspect’s
housing history. The investigator correctly reported that the alleged
victim and suspect were housed together from May 2024 through
July 2024. However, in another section of the report, the investigator
mistakenly stated that the alleged victim and suspect were housed
together from September 2023 through November 2023. We confirmed
82. 28 C.F.R. section 115.71(c); Penal Code section 2639; and DOM Sections 54040.8.1 and
54040.9–12.2.
Office of the Inspector General, State of California

PREA Allegations, Special Review, August 2025 | 27
through prison records that the alleged victim did not arrive at the prison
until May 2024, six months later.
In another case, an alleged victim reported a PREA violation in
March 2024, on the same day the incident allegedly occurred, but the
investigator incorrectly documented in his report the alleged violation
occurred in January 2024. The error likely led to the investigator’s
decision to not transport the alleged victim to a forensic medical
examination because he believed the incident occurred two months
earlier. Consequently, the opportunity to obtain medical evidence
supporting or refuting the PREA allegation was lost.
In four cases we reviewed, the investigative reports included information
not documented elsewhere. In one case, the investigator concluded an
allegation was substantiated citing, “Two independent sources [who]
provided similar information.” However, the investigative report only
documented one source witness. Furthermore, the investigator relied
only on the witness’s statement to substantiate the allegation even
though the witness had been previously found to have committed a
PREA violation against the suspect.
In another separate case, an investigator reported that an alleged PREA
victim did not know what object the suspect used to sodomize him.
However, on a sexual assault interview guideline form used to gather
information about the allegation, the same investigator documented that
the suspect used his penis to anally rape the alleged victim. In the third
case, it was unclear from the investigative report who received the initial
PREA allegation. The investigative report stated that a “yard supervisor”
received the allegation, but there was no documentation that the
investigator identified the “yard supervisor” or contacted the individual
to gather additional information. In the fourth case, the investigator
incorrectly named a different incarcerated person as the alleged victim
when documenting his review of the alleged victim’s PREA case history.
The incorrectly named person was not involved in the PREA allegation
being investigated.

Chapter 3. The Prisons’ Institutional PREA
Review Committees Did Not Provide Proper
Oversight to Ensure That Applicable Laws,
Regulations, and Policy Were Followed
PREA review committees are responsible for thoroughly reviewing
allegations to ensure staff followed federal and state laws, as well
as departmental policy and guidelines when responding to PREA
allegations.83 In nearly all incidents we analyzed, review committees did
not provide proper oversight to determine if investigators used standard
investigative techniques to gather evidence and corroborate allegations.
In many cases, review committees failed to identify significant short
comings that should have required investigators to complete additional
work, or to receive training on conducting thorough and adequate
investigations.
In the cases we reviewed, we also found no evidence that review
committees meaningfully discussed the investigations they reviewed.
Lastly, review committees did not review several PREA incidents within
the time frame required by departmental policy. In one case, the review
committee finalized its incident review before the PREA investigation
had been completed.
Quality Control Among the Prisons’ PREA Review Committees Is Poor
and Needs Improvement
Review committees are responsible for providing quality control for
prisons’ PREA reporting and response processes.84 However, as explained
earlier in this report, we identified many deficiencies in investigative
reports we reviewed. If review committees had properly reviewed
those investigations, they would have identified the same deficiencies
and either required investigators to conduct additional work, or made
recommendations for improvement, as departmental policy requires.
In one case, an alleged victim identified the suspect and an officer who
may have witnessed his sexual assault, but the investigator did not
interview either individual. Furthermore, in his report, the investigator
stated a forensic medical examination was not warranted due to the lapse
of time from when the incident allegedly occurred. However, a PREA
response supervisor reported that both the alleged victim and suspect
had been transported for forensic medical examinations. Had the prison’s
review committee reviewed the investigative report as we had, the
committee would have identified the blatant discrepancy and requested
clarification on this very important issue. The committee would have

also identified the investigator’s failure to interview both the suspect and
witnesses and likely required follow up.
In another case, an alleged victim reported in January 2024 that he
was allegedly forced to engage in nonconsensual sex acts. However,
the investigator did not attempt to interview the alleged victim until
41 days after he reported the allegation. Timely interviews are critical
in all investigations, especially rape investigations. Consequently,
departmental PREA training guidelines state investigators should
complete victim interviews promptly to help ensure alleged victims
provide specific details of the incidents before their memories fade.85
Clearly, not attempting to interview the alleged victim until 41 days
after the reported incident is a significant delay, and the prison’s review
committee should have questioned the investigator about the delay.
The deficiencies cited in this report are compounding evidence that
the review committees did not conduct meaningful PREA incident
reviews. While we bring attention to the deficiencies and errors found
in the cases we reviewed, we have not analyzed the significance of
these deficiencies and errors to determine whether they would have
altered investigation outcomes. However, if review committees had
thoroughly reviewed PREA investigations as PREA standards and
departmental policy requires, both the department and the public would
have been assured that investigators took the allegations seriously
and collected the necessary information and evidence to substantiate
investigation outcomes.86
Most PREA Review Committee Documentation Was Poor,
Lacking Evidence of Meaningful Discussion or Recommendations
for Improvement
In general, we found that documentation of review committee meetings
lacked meaningful evidence that committees discussed PREA allegations
and the corresponding investigative report(s) as required by PREA
standards and departmental policy.87 Most prison review committee
members use a template checklist to document their participation during
meetings. The checklist includes “yes” and “no” checkboxes for specific
requirements review committee members must verify, as illustrated
on Figure 2 on page 6.88 The template also includes a space for review
committee members to add additional information and comments
regarding each checklist item.89

We found that review committee members rarely did more than check
the boxes on the checklist. In many cases, committee members only
partially completed the checklist, and some committee members
failed to complete the checklist at all. As illustrated in Figure 6 below,
24 of 74 case files (32 percent) of PREA incidents we reviewed did not
contain review committee meeting checklists or any supplemental
documentation to show the committees reviewed the incidents.
Furthermore, of the 50 case files (68 percent) that contained review
committee meeting checklists, 27 (54 percent) of the checklists were
unsigned or incomplete with unanswered questions or missing pages.
The review committee checklist includes one item bulleted and
underlined for emphasis, “Ensure all discussions are documented.”

the PREA Review Committee from March 1, 2024, through August 31, 2024.
The checklists we reviewed rarely included evidence that review
committees discussed investigations, let alone documented those
discussions. Our inspectors attended at least 48 review committee
meetings at 18 prisons and found the meetings were brief and lacked
robust discussion. At four prisons, the review committee meetings
we reviewed lasted no more than five minutes, at three they lasted no
more than 10 minutes, and at another three they lasted no more than
15 minutes. Finally, review committee meetings we attended at two
prisons lasted between 15 and 35 minutes. At two prisons, the length of
meetings ranged from between 15 and approximately 35 minutes.

PREA Allegations, Special Review, August 2025 | 31
We found discussion among the review committee members at some
meetings we attended was limited to reading the questions from the
templated checklist and then asking investigators if the allegations were
substantiated, unsubstantiated, or unfounded. The review committee
would then quickly move to the next investigation scheduled on the
agenda until all incidents were “reviewed.” Based on our observations
during the meetings we attended, it is clear that most committee
members did little to prepare for the meetings and did not fulfill their
responsibilities under departmental policy. The poor documentation
of what actions committee members took during review, and the
insufficient reviews as evidenced by short, superficial meetings, causes
us to question the department’s commitment to ensuring a thorough and
accurate PREA review process.
Finally, PREA standards and departmental policy require review
committees to prepare reports of all findings and recommendations for
improvement after each meeting:90
[A review committee shall] prepare a report of its findings
and any recommendations for improvement.91
As detailed at length above, we found deficiencies in virtually all PREA
investigations we reviewed, but review committees did not identify
any of these deficiencies. We did not find documentation that review
committees made any recommendations to ensure prisons implemented,
revised, or enforced procedures necessary to properly and efficiently
respond to allegations in the cases we reviewed. If review committees do
not conduct thorough incident reviews, investigators will likely continue
to inadequately investigate PREA allegations.
Review Committees Did Not Always Timely Review PREA Allegations
Departmental policy requires review committees to review PREA
allegations within 60 days of when the victim or a third party reported
the incident, or within 30 days of completion of the investigation,
whichever is sooner.92 Review committees did not conduct incident
reviews within 60 days of the date the PREA allegation was first reported
in 27 percent (20 of 74) of the cases we reviewed. Prisons also did not hold
review committee meetings within 30 days of the closure of investigation
in 27 percent (20 of 74) of cases we reviewed.
Figures 7 and 8 below provide breakdowns of the time review committees
took to conduct incident reviews from when the allegations were
first received by the prison, and from the dates the investigations
were concluded.

Notably, review committee members did not document any explanation
as to why the reviews were delayed on the meeting checklists in any of
the cases we reviewed. Timely review of PREA allegations is essential
to ensure investigations—which carry significance to both victims and
suspects—are both thorough and supported. For victims, a timely review
can bring justice and resolution to a potential crime. For suspects, a
timely review is essential for either exoneration, or to explain the next
steps in the investigation process.
In one case we reviewed, we also found that a review committee finalized
its review nine days before the investigator submitted a final report.
There is no evidence the review committee looked at the investigative
report after it was completed.
Review committee members have a critical role in the PREA review
process. They provide quality control to ensure the department’s
policies, practices, and protocols comply with federal and state laws.
Unfortunately, we did not find this to be the case in the 74 PREA
investigations we reviewed. If neither the department nor the review
committee is committed to improving the PREA review process and
holding staff accountable for failing to follow departmental regulations
and policy, then staff will continue to perform poorly, as identified in
this report.
Furthermore, if the incarcerated population has the impression
the department does not thoroughly review PREA allegations or
investigations, the population may be less likely to report sexual
misconduct. Consequently, the number of sexual assault victims may
be underreported in California’s prisons. This ultimately undermines
the department’s policy of zero tolerance for sexual misconduct and
its mission to provide a safe, humane, secure environment, free from
sexual misconduct.93

Chapter 4. Recommendations
1. The department should require all PREA allegation interviews to be
audio or video recorded.
a. The department should require a manager, or other
designated staff to confirm on a sample basis that
information from recorded PREA interviews is accurately
and thoroughly documented in investigators’ reports.
2. The department should ensure all investigators conducting PREA
investigations receive specialized PREA investigator training as
required by law and departmental policy.
a. The department should consider requiring that all
Investigative Services Unit investigator staff receive
specialized PREA training.
3. Prison wardens or delegates should require corrective action if
staff fail to comply with law or departmental policy when receiving,
responding to, or investigating PREA allegations.
4. The department should implement monitoring processes to ensure:
a. All staff follow departmental policy and training procedures
when receiving and responding to PREA allegations.
b. Staff who conduct PREA investigations properly apply
the standard investigative techniques included in the
departmental specialized PREA training program for
investigators.
c. Investigative reports are complete and accurate according to
case documentation.
d. PREA review committees fulfill all their responsibilities
under departmental policy.
5. The department should identify and document areas for corrective
action when PREA review committee members do not fulfill all their
responsibilities under departmental policy.

Appendix A. Departmental Investigations of
PREA Allegations We Reviewed and Determined
to Be Inadequate for One or More Reasons
In this appendix, we present our determinations for 67 of the 74 PREA
investigations we reviewed to be inadequate for one or more reasons.
We used our professional judgment, criteria set forth in PREA standards
and departmental policies and procedures, and recommended practices
outlined in the department’s PREA training manuals. We assessed
the appropriateness of the investigative techniques applied to each
investigation; interviews conducted with alleged victims, suspects,
and witnesses; evidence collected; and the accuracy and thoroughness
of the investigative report compared to supporting documentation.
Our qualitative assessments, however, were not intended to reflect the
validation or invalidation of the investigator’s investigation outcome
determinations. Below, we present the primary assessment questions and
the general methodology we applied to assess each.
1. Did the investigator interview the victim?
We evaluated whether the investigator interviewed the victim
to gather information pertaining to the allegation, including
pertinent details of the events requiring investigation, possible
witnesses and available evidence.
2. Did the investigator interview the suspect?
We evaluated whether the investigator interviewed the alleged
suspect to gather information pertaining to the allegation,
including pertinent details of the events requiring investigation,
possible witnesses and available evidence.
3. Did the investigator attempt to identify witnesses?
We evaluated whether the investigator attempted to identify
potential staff or incarcerated person witnesses, if applicable,
to gather information pertaining to the allegation, including
pertinent details of the events requiring investigation, possible
witnesses and available evidence.
4. Did the investigator interview witnesses?
We evaluated whether the investigator interviewed potential staff
or incarcerated witnesses, if identified.
5. Did the investigator consider forensic medical examination results
or other medical reports, as applicable?
We evaluated whether the investigator considered the results
from forensic medical examinations, the Medical Report of
Injury or Unusual Occurrence, or other medical reports, as
applicable, to determine the investigation outcome.
Office of the Inspector General, State of California
Return to Contents
PREA Allegations, Special Review, August 2025 | 39
6. Did the investigator obtain and review other evidence, other than
audio video surveillance system (AVSS) footage?
We evaluated whether the investigator attempted to gather
evidence, such as but not limited to, reviewing phone records,
mail, clothing, bedding, housing history, and other relevant
matter to support or refute allegations of sexual misconduct.
7. Did the investigator review prior complaints and reports sexual
abuse that may be relevant to the allegation?
We evaluated whether the investigator reviewed prior
complaints, disciplinary history, and reports of sexual abuse
of individuals who were subjects of the PREA investigation
to establish any relevant history as a basis to decide on the
investigation outcome.
8. Did we find other discrepancies and shortcomings in the
investigation, or investigative reporting?
We evaluated the investigation report, and relevant
documentation for overall thoroughness of the report,
including whether the reports were complete and accurate.
We considered attributes including, but not limited to, the
timeliness of interviews; follow-up to alleged victim, suspect,
and witness statements; follow-up with evidence collected; and
recorded interviews and documentation to support analysis and
conclusions.

Appendix E. Scope and Methodology
California Penal Code section 6126, subdivisions (b) and (c) authorize
the OIG to initiate reviews of the department’s policies, practices, and
procedures. The Inspector General initiated this review focused on
PREA allegations against incarcerated people reported at California
State prisons. Our inspectors attended review committee meetings,
reviewed PREA investigative reports and related documentation,
interviewed and met with staff as necessary, and analyzed the results of
PREA investigations.
We judgmentally selected 74 PREA allegations that underwent incident
reviews by the review committees at 23 California prisons from March
1, 2024, through August 31, 2024, for the purposes of this review. While
OIG inspectors did not attend all IPRC meetings, we focused our
selection of PREA allegations on the general criteria listed below:
• We prioritized PREA allegations of nonconsensual sexual
contact and abusive sexual contact.
• We prioritized PREA allegations that involved transgender
incarcerated people.
• We considered the level of injury sustained by the PREA
victim.
• We considered the incarcerated person’s housing
assignment and classification.

The Department’s Response to Our Report

OFFICE OF THE SECRETARY

August 15, 2025
Ms. Amarik Singh
Office of the Inspector General
10111 Old Placerville Road, Suite 110
Sacramento, CA 95827
Dear Ms. Singh:
The California Department of Corrections and Rehabilitation (CDCR) thanks the Office of the
Inspector General (OIG) for the opportunity to review the draft report titled Special Review of the
California Department of Corrections and Rehabilitation’s Response to Incarcerated-Person-on-
Incarcerated-Person Allegations Under the Prison Rape Elimination Act.
CDCR would like to highlight the Department’s consistent record of full compliance in federal
audits. These audits, conducted by Department of Justice-certified PREA auditors, unaffiliated
with CDCR, substantiate CDCR’s commitment to meeting and exceeding federal standards.
These favorable outcomes stand in contrast to the findings reported by the OIG, raising concerns
about the methodology employed and warranting a thorough reconsideration of its conclusions.
Upon reviewing the OIG's draft report, it became apparent that the criteria utilized to determine
the rating of “inadequate” were not clearly articulated. Particularly concerning, it appears there
may have been a conflation of the roles and responsibilities of the Institutional PREA Review
Committee (IPRC) and the Institution Executive Review Committee (IERC). While both
committees hold similarities, they are distinctly established to review different criteria, thus
warranting separate evaluations based on their respective mandates.
The DOM Section 54040.17 delineates the specific criteria that the IPRC shall review, focused
primarily on ensuring preventive measures and addressing systemic issues related to sexual
abuse. Conversely, the IERC, as outlined in DOM Section 51020.19.5, is tasked with conducting a
thorough assessment in compliance with use of force policies and procedures. The possible
conflation of these two processes may have led to an assessment of inadequacies that do not
account for the specific criteria set forth by federal standards and departmental policies. For
example, the OIG indicates that investigators did not consistently record video or audio record
interviews, marking this as an inadequacy; however, such a mandate is not established in CDCR's
policies. Furthermore, the assertion that review committees failed to identify inadequacies in
67 out of 74 investigations may not hold when considering the differing responsibilities of the
IPRC and IERC. These findings paint an inaccurate picture of the CDCR's adherence to federal
standards and internal policy, leading to an unjust classification of inadequacy.

The Department acknowledges that certain institutional practices related to Incarcerated
Person-on-Incarcerated Person investigations under the Prison Rape Elimination Act (PREA)
present opportunities for improvement. CDCR is exploring opportunities to augment our
resources to enable the unit to offer increased support and training to institutional investigators
and PREA Compliance Managers. Our goal is to strengthen the unit’s capacity to deliver
comprehensive oversight of investigative processes, ensuring sustainable practices in alignment
with the Code of Federal Regulations (28 CFR Part 115), the Department Operations Manual
(DOM), and applicable provisions of the California Penal Code.
In conclusion, while the OIG report identifies several opportunities for improvement, it is crucial
that the evaluative framework accurately reflects the established standards and practices
governing our investigations. The Department remains dedicated to refining its processes and
ensuring the safety and well-being of all individuals within its facilities.
We remain dedicated to addressing the issues identified and look forward to ongoing
collaboration in fostering transparency and accountability. Please advise us of the anticipated
release date for the final report.
If you have any questions, contact me at (916) 323-6001.
Sincerely,
JEFF MACOMBER
Secretary

The Office of the Inspector General’s
Reply to the Department’s Response
Thank you for your response to our draft report titled Special Review of
the California Department of Corrections and Rehabilitation’s Response to
Incarcerated-Person-on-Incarcerated-Person Allegations Under the Prison
Rape Elimination Act.
Regarding your concern that our determinations of adequacy and
inadequacy were based on either a conflation of the role of the
Institutional PREA Review Committee (IPRC) with the role of the
Institution Executive Review Committee (IERC) or the department’s
failure to record interviews, neither IPRC performance nor the failure to
record interviews factored into our assessment of the 74 investigations
we reviewed. Appendix A to the report sets forth a detailed explanation
of the eight criteria we used to assess the adequacy of each investigation
we reviewed during the course of this special review.
Similarly, the portions of the report that discuss the performance of
the department’s IPRCs are based solely on departmental policies and
training on the role and responsibilities of IPRCs. We did not reference
or apply criteria specific to IERCs in the report.
Respectfully,
Amarik K. Singh
Inspector General
