OAKLAND — A retired judge found the Oakland Police department failed the teenage victim of police sexual misconduct and the department’s investigations into her claims were “wholly inadequate,” according to a report by the department that was released Friday.

Reward rises for West Oakland fatal shooting information In the same report, however, the department said it has no plans to further discipline employees for their roles in the heavily-criticized investigations.

Retired Judge Wayne D. Brazil’s conclusion was included in a report by the Oakland police department to the federal judge overseeing OPD’s court-ordered reforms. Brazil’s findings agree with those published in June by Edward Swanson and Audrey Barron, two attorneys appointed by judge to investigate the sex scandal that involved several officers.

Brazil joined Chief Anne Kirkpatrick as part of OPD’s self-examination of how the department handled the criminal and internal affairs investigations related to the case. The “critical incident review” was released in court filings Friday.

“(the Judge Brazil pointed out several troubling events that occurred during the investigation,” according to the report. “Judge Brazil agreed with the Swanson Report’s conclusion that OPD had a culture that dismissed (the victim), failed to recognize her as a victim and dismissed her as not being credible.”

The scandal was uncovered when Oakland Officer Brendan O’Brien committed suicide in September 2015 and left a note saying his fellow officers were involved with the teenage daughter of a police dispatcher who went by the name Celeste Guap.

The young woman’s claims led to the arrests and prosecution of multiple police officers on various charges, though some have had their charges reduced or thrown out. Earlier this week, a judge tossed aside a case against Oakland Officer Brian Bunton.

Despite criticism of the way homicide detectives interviewed the woman and how internal affairs went about investigating the probe, Friday’s report said officers will undergo further training and participate in culture working groups and individual reflection.

No other officers will face discipline, the report said.

“There have been calls for department members to be held accountable through a public disciplinary process to atone for the failures of the investigation,” the report read. “OPD has taken significant action, including terminations and criminal investigations that led to prosecutions. Based on the totality of the circumstances, including the facts elicited through the investigation and in-depth critical incident review, further discipline is not warranted.”

Oakland police and city leaders return to federal court on Oct. 2 as part of the department’s 14-year-long federal oversight program.

“The Oakland Police Department fully accepts that it failed (the teenage sex victim), the community and its own members by failing to realize the gravity of the allegations and (the victim’s) vulnerable status,” the report read.
