A woman branded as the “Ketamine Queen” pleaded guilty Wednesday to selling Matthew Perry the drug that killed him, becoming the fifth and final defendant charged in Perry’s overdose death to admit guilt.

Jasveen Sangha pleaded guilty to five federal charges, including providing the ketamine that led to Perry’s death. Her trial had been planned to start later this month.

Perry’s mother, Suzanne Perry, and his stepfather, “Dateline” reporter Keith Morrison, sat in the audience. It was their first time attending court proceedings since the announcement of the indictments one year ago.

Wearing tan jail garb, Sangha stood in court Wednesday next to her attorney Mark Geragos as she repeated “guilty” five times when U.S. District Court Judge Sherilyn Peace Garnett asked for her pleas.

Before that, she answered “yes, your honor” to dozens of procedural questions, hedging slightly when the judge asked if she knew the drugs she was giving to co-defendant and middleman Erik Fleming were going to Perry.

“There was no way I could tell 100%,” she said. She later added, to a similar question on vials of ketamine she gave to Fleming, that “I didn’t know if all of them or some of them” were bound for Perry. The comments didn’t affect her plea agreement.

Prosecutors had cast Sangha, a 42-year-old citizen of the U.S. and the U.K., as a prolific drug dealer who was known to her customers as the “Ketamine Queen,” using the term often in press releases and court documents.

Making good on a deal she signed on Aug. 18, Sangha pleaded guilty to one count of maintaining a drug-involved premises, three counts of distribution of ketamine, and one count of distribution of ketamine resulting in death.

“She feels horrible about all of this. Nobody wants to be in the chain of causation for lack of a better term,” Geragos said outside the federal courthouse in downtown Los Angeles. “She feels horrible and she’s felt horrible since day one.”

Sangha admitted to selling drugs directly to 33-year-old Cody McLaury, who died from an overdose in 2019. McLaury had no connection to Perry.

Prosecutors agreed to drop three other counts.

Geragos, whose other clients have included Michael Jackson, Chris Brown and the Menendez brothers, told the judge that the deal was reached “after a robust back-and-forth with the government.”

The final plea deal came a year after federal prosecutors announced the indictments in Perry’s Oct. 28, 2023 death after a sweeping investigation.
