James Sexton thinks Operation Pandora’s Box is behind him. When he reports a superior officer for misconduct, he is branded a snitch and treated as a pariah. Ostracized and scared, he does what he once thought unthinkable: he begins feeding information about the Sheriff’s Department to the FBI, and tells a grand jury about the scheme to hide Anthony Brown. In the U.S. Attorney’s first major thrust against the sheriff’s department, Sexton becomes one of 18 current or former sheriff’s employees to be indicted. Desperate to keep his badge, he decides the fight the charges, and his lawyer portrays him as the “Walter Middy” of the scandal, a man who exaggerated his role. Nevertheless, a jury finds him guilty and he begins his prison sentence.

Sexton’s decision to talk to investigators opened a rare window into the inner workings of the Sheriff’s Department. His testimony about Anthony Brown tied deputies and supervisors to a widening obstruction scandal. The story is reported and narrated by Chris Goffard, the Los Angeles Times journalist behind Dirty John.

When Lee Baca took over the LA County Sheriff’s Department in 1998, he inherited a scandal-plagued agency. He built a reputation as a progressive reformer, and his jail-education programs were celebrated. But the feds notice that investigations into his agency always seem to evaporate when he gets involved. By 2011, he is 70 years old and has run the department for 13 years. Furious about the FBI’s probe into his jails, Baca has Leah Marx surveilled. Two of his sergeants appear at her apartment and threaten her with arrest. Allegations emerge about the beating of a jail visitor name Gabriel Carrillo. The feds have expanded their probe beyond civil rights violations. Can they make a case for obstruction of justice? How high does the misconduct go?

Baca’s clash with the FBI revealed how deeply the department was in turmoil. Allegations of intimidation and the beating of visitor Gabriel Carrillo turned a civil rights probe into one of Los Angeles’ most significant corruption cases. Host Chris Goffard, from the Los Angeles Times and creator of Dirty John, traces how the investigation escalated to obstruction of justice.

Topics in this episode include: Sheriff Lee Baca, Los Angeles County Jail scandal, Gabriel Carrillo beating, FBI investigation, police corruption.

After an inmate sucker-punches James Sexton, he defies the jail’s unwritten rules by failing to exact violent retribution, and finds himself ostracized by his peers. But he becomes an expert in the antiquated jail computer system and eventually wins promotion to an elite jail-intelligence unit. Leah Marx has a cell phone smuggled to inmate-informant Anthony Brown, part of the FBI’s increasingly ambitious scheme to catch dirty jailers. Jailers quickly discover the phone, however, and trace it to the FBI. Scrambling to hide Brown from the feds, the department enlists Sexton, who helps change Brown’s name in the computer system and dubs the plan Operation Pandora’s Box. For 18 days, from August-Sept. 2011, Marx struggles to find her informant.

The effort to erase Anthony Brown from jail records showed how far leaders would go to shield themselves. A young deputy became central to the cover-up, and what began as a contraband phone case quickly spiraled into an obstruction probe. Reporter Chris Goffard, who previously told the story of Dirty John, guides listeners through this extraordinary clash between the Sheriff’s Department and the FBI.
