One of the physicians indicted in connection with Matthew Perry’s murder has agreed to plead guilty to providing ketamine to the actor.

According to a plea agreement filed on Monday, June 16, in Los Angeles and obtained by PEOPLE, Dr. Salvador Plasencia, a licensed physician known as Dr. P., will plead guilty to four counts of ketamine distribution.

The plea entails a potential penalty of forty years in jail. Plasencia—one of five people facing criminal charges in Perry’s death—is expected to enter the plea in the coming weeks.

Prior to the plea deal, the doctor faced numerous more accusations, including seven total counts of distribution of ketamine and two counts of changing and forging papers or records relevant to the federal inquiry into Perry’s death.

Plasencia was among five people charged last year in connection with Perry’s October death. He could face up to 40 years in jail for distributing ketamine on four separate occasions.

On October 28, 2023, the popular Friends actor died as a result of an accidental drug overdose. An autopsy later showed Perry died from acute effects of ketamine, in addition to other contributing factors such as drowning, coronary artery disease, and effects from buprenorphine, a medication used to treat opioid use disorder.

Over six months after his death, the Los Angeles Police Department was conducting a formal investigation into how the actor obtained the ketamine after the Los Angeles County Medical Examiner-Coroner closed their investigation in December 2023.

In August 2024, Plasencia and four other people were arrested on charges in connection with the actor’s death.

Jasveen Sangha—who U.S. Attorney Martin Estrada claimed is referred to as “The Ketamine Queen”—is “charged with one count of conspiracy to distribute ketamine, one count of maintaining a drug-involved premises, one count of possession with intent to distribute methamphetamine, one count of possession with intent to distribute ketamine, and five counts of distribution of ketamine, the Department of Justice announced at the time.

According to the Associated Press, Sangha is due to stand trial in August. She has pled not guilty, making her the only individual charged in Perry’s killing who has not made a plea deal.

The other defendants all pleaded guilty in August 2024. Dr. Mark Chavez pleaded to one count of conspiring to distribute ketamine. Kenneth Iwamasa, Perry’s live-in personal helper, pled guilty to one count of conspiracy to distribute ketamine that resulted in death in August. Erik Fleming, an alleged drug dealer, pled guilty to one count of conspiracy to sell ketamine and one count of ketamine distribution that resulted in death.

Federal prosecutors claim that the five defendants “took advantage” of Perry for their own “profit.”

According to the Justice Department, Plasencia allegedly contacted Chavez, who was also a doctor and previously operated a ketamine clinic, to obtain the substance to sell to Perry. In text conversations with Chavez, Plasencia reportedly discussed how much to charge Perry for the ketamine, adding, “I wonder how much this moron will pay” and “Let’s [sic] find out,” the DoJ stated.

The counsel also stated that the defendants were aware of what the harmful implications on Perry’s health may be due to their choices. Estrada claimed the prosecution discovered text messages in which Sangha wrote, “I wouldn’t do it if there wasn’t a chance of me making some money for doing this.”

According to Estrada, after Perry’s death, the defendants attempted to “cover up” their involvement, with Sangha allegedly texting another defendant, “Delete all our messages.”
