(a) When the agency conducts its own investigations into allegations of sexual abuse and sexual harassment, it shall do so promptly, thoroughly, and objectively for all allegations, including third-party and anonymous reports.

(b) Where sexual abuse is alleged, the agency shall use investigators who have received special training in sexual abuse investigations pursuant to § 115.34.

(c) Investigators shall gather and preserve direct and circumstantial evidence, including any available physical and DNA evidence and any available electronic monitoring data; shall interview alleged victims, suspected perpetrators, and witnesses; and shall review prior complaints and reports of sexual abuse involving the suspected perpetrator.

(d) When the quality of evidence appears to support criminal prosecution, the agency shall conduct compelled interviews only after consulting with prosecutors as to whether compelled interviews may be an obstacle for subsequent criminal prosecution.

(e) The credibility of an alleged victim, suspect, or witness shall be assessed on an individual basis and shall not be determined by the person's status as inmate or staff. No agency shall require an inmate who alleges sexual abuse to submit to a polygraph examination or other truth-telling device as a condition for proceeding with the investigation of such an allegation.

(f) Administrative investigations:

(1) Shall include an effort to determine whether staff actions or failures to act contributed to the abuse; and

(2) Shall be documented in written reports that include a description of the physical and testimonial evidence, the reasoning behind credibility assessments, and investigative facts and findings.

(g) Criminal investigations shall be documented in a written report that contains a thorough description of physical, testimonial, and documentary evidence and attaches copies of all documentary evidence where feasible.

(h) Substantiated allegations of conduct that appears to be criminal shall be referred for prosecution.

(i) The agency shall retain all written reports referenced in paragraphs (f) and (g) of this section for as long as the alleged abuser is incarcerated or employed by the agency, plus five years.

(j) The departure of the alleged abuser or victim from the employment or control of the facility or agency shall not provide a basis for terminating an investigation.

(k) Any State entity or Department of Justice component that conducts such investigations shall do so pursuant to the above requirements.

(l) When outside agencies investigate sexual abuse, the facility shall cooperate with outside investigators and shall endeavor to remain informed about the progress of the investigation.
