The former warden of an abuse-plagued federal women’s prison known as the “rape club” goes on trial Monday, accused of molesting inmates and forcing them to pose naked in their cells.

Ray J. Garcia, who retired after the FBI found nude photos of inmates on his government-issued phone last year, is among five workers charged with abusing inmates at the federal correctional institution in Dublin, California, and the first to go to trial.

Opening statements and the first witnesses are expected Monday in federal court in Oakland. Garcia, 55, has pleaded not guilty. If convicted, he would face up to 15 years in prison.

An Associated Press investigation in February revealed a culture of abuse and cover-up that had persisted for years at the prison, about 21 miles (34 kilometers) east of Oakland. That reporting led to increased scrutiny from Congress and pledges from the federal Bureau of Prisons that it would fix problems and change the culture at the prison.

Garcia is charged with abusing three inmates between December 2019 and July 2021, but jurors could hear from as many as six women who say he groped them and told them to pose naked or in provocative clothing. U.S. District Judge Yvonne Gonzalez Rogers said prosecutors can call three additional accusers as witnesses, even though their allegations are not part of his indictment.

Garcia’s lawyer has repeatedly declined to comment, saying he would respond to the charges “only through the court process.” Court filings indicate the defense plans to argue that Garcia took pictures of one inmate because he wanted documentation that she was breaching policy by standing around naked.

The case, with shades of #MeToo behind bars, is also likely to put a spotlight on the Bureau of Prisons, calling into question its handling of sexual abuse complaints from inmates against staff and the vetting process for the people it chooses to run its prisons.

Garcia was promoted from associate warden to warden in November 2020 while he was still abusing inmates, prosecutors say. The Bureau of Prisons has said it didn’t find out about the abuse until later. Garcia is the highest-ranking federal prison official arrested in more than 10 years.

The agency’s new director, Colette Peters, has reiterated the agency’s zero-tolerance policy for staff sexual misconduct and has called for harsher punishment for workers who commit abuse. But as abuse raged at Dublin, the process for reporting it was inherently broken.

Garcia was in charge of staff and inmate training on reporting abuse and complying with the federal Prison Rape Elimination Act at the same time he was committing abuse, prosecutors say, and some inmates say they were sent to solitary confinement or other prisons for accusing employees of abuse.

Prosecutors say Garcia tried to keep his victims quiet with promises that he’d help them get early release. He allegedly told one victim he was “close friends” with the prison official responsible for investigating staff misconduct and couldn’t be fired. According to an indictment, he said he liked to cavort with inmates because, given their lack of power, they couldn’t “ruin him.”

Garcia is also accused of ordering inmates to strip naked for him as he made his rounds and of lying to federal agents who asked him if he had ever asked inmates to undress for him or had inappropriately touched a female inmate.

“If they’re undressing, I’ve already looked,” Garcia told the FBI in July 2021, according to court records. “I don’t, like, schedule a time like, ‘You be undressed, and I’ll be there.’”

Garcia was placed on administrative leave before retiring, He was arrested in September 2021.

The inmates were not identified in court papers. The AP generally does not name people who say they are victims of sexual assault unless they consent to being identified.

All sexual activity between a prison worker and an inmate is illegal. Correctional employees enjoy substantial power over inmates, controlling every aspect of their lives from mealtime to lights out, and there is no scenario in which an inmate can give consent.

Earlier this month, Deputy Attorney General Lisa Monaco directed federal prosecutors across the U.S. to “consider the full array of statutes,” including the federal Violence Against Women Act in cases involving Bureau of Prisons employees who are accused of sexual misconduct.

In those cases, Monaco said prosecutors should consider asking judges for sentences that go beyond the federal guidelines if the sentence recommended in the guidelines isn’t “fair and proportional to the seriousness of the offenses.”

Monaco, a key player in the Justice Department’s attempt to reform the federal prison system, meets regularly with Bureau of Prisons director and the department’s inspector general and has met with U.S. attorneys and FBI Director Christopher Wray to emphasize the need to pursue charges when prison employees commit misconduct.

Of the four other Dublin workers charged with abusing inmates, three have pleaded guilty and one is scheduled to stand trial next year. James Theodore Highhouse, the prison’s chaplain, is appealing his seven-year prison sentence, arguing that it was excessive because it was more than double the recommended punishment in federal sentencing guidelines.
