(LOS ANGELES) — The second of two doctors who were convicted in connection with Matthew Perry’s ketamine death is set to be sentenced on Tuesday.

Mark Chavez is one of five people charged and convicted in connection with the “Friends” actor’s 2023 overdose death. He pleaded guilty last year to one count of conspiracy to distribute ketamine, admitting to selling fraudulently obtained ketamine to another doctor, Salvador Plasencia, that was then sold to Perry in the weeks before the actor died from an overdose.

The two doctors did not provide the ketamine that ultimately killed Perry, who was discovered unresponsive in a jacuzzi at his Los Angeles home in October 2023 at the age of 54. Though federal prosecutors said they knew that the actor had a history of substance abuse and that the drug would be administered without medical supervision.

Chavez faces up to 10 years in prison, prosecutors said.

The government asked for a sentence of six months home confinement that includes a two-year term of supervised release as well as at least 300 hours of community service. Prosecutors said Chavez, a former operator of a ketamine clinic, provided Plasencia with vials of liquid ketamine and ketamine lozenges that had been obtained by submitting a fraudulent prescription in the name of a patient without that patient’s knowledge or consent.

“As the Drug Enforcement Administration and Medical Board investigators closed in on defendant’s illegal ketamine sales, defendant initially lied and tried to evade responsibility,” the government said in a filing ahead of sentencing. “To defendant’s credit, however, his story continued, and became one of accountability.”

The government said that once confronted with his criminal acts, Chavez “expediently accepted responsibility and agreed to cooperate with the government’s investigation.”

Chavez’s defense attorneys asked for three years of supervised release, arguing in a filing ahead of sentencing that his conduct was “limited and peripheral” and “far removed from the tragic events of October 28, 2023.”

They noted that Chavez had never met Perry, entered his home or administered medication to him, and that he did not supply the ketamine that caused his death. They also said he “accepted responsibility early in this case and signed a plea agreement prior to any indictment, agreed to cooperate, and voluntarily surrendered his medical license even before his detention hearing.”

“The consequences Mr. Chavez has already faced are significant,” his attorneys, Matthew Binninger and Zach Brooks, wrote. “Once a practicing emergency room physician, he lost his profession, suffered public disgrace, and now earns a living as an Uber driver. He has remained compliant with all terms of pretrial supervision and continues to demonstrate sincere regret for his actions.”

Both Chavez and Plasencia gave up their medical licenses after pleading guilty.

According to Plasencia’s plea agreement, one of his patients introduced him to Perry on Sept. 30, 2023, with the unidentified patient referring to the actor as a “‘high profile person’ who was seeking ketamine and was willing to pay ‘cash and lots of thousands’ for ketamine treatment,'” according to Plasencia’s plea agreement.

Plasencia contacted his mentor, Chavez, to discuss Perry’s request for ketamine and purchased vials of liquid ketamine and ketamine lozenges from him, according to the agreement.

In discussing how much to charge Perry, Plasencia said in text messages to Chavez, “I wonder how much this moron will pay” and “Lets [sic] find out,” prosecutors said.

Plasencia admitted to distributing 20 vials of ketamine, ketamine lozenges and syringes to Perry and the actor’s live-in assistant, Kenneth Iwamasa, between Sept. 30, 2023, and Oct. 12, 2023.

Plasencia administered ketamine to Perry at the actor’s home on several occasions and left vials and lozenges with Iwamasa to administer, according to the plea agreement.

Plasencia was sentenced to 30 months in prison earlier this month.

Iwamasa admitted in court documents to administering the ketamine on the day that Perry died, pleading guilty in August 2024 to one count of conspiracy to distribute ketamine causing death. He is scheduled to be sentenced on Jan. 14, 2026, and faces up to 15 years in prison.

Two other defendants in the case — Erik Fleming and Jasveen Sangha — admitted to distributing the ketamine that killed Perry.

Prosecutors said Sangha worked with Fleming to distribute ketamine to Perry, and that in October 2023, they sold the actor 51 vials of ketamine, which were provided to Iwamasa.

Fleming pleaded guilty in August 2024 to one count of conspiracy to distribute ketamine and one count of distribution of ketamine resulting in death. He is scheduled to be sentenced on Jan. 7, 2026, and faces up to 25 years in prison.

Sangha, allegedly known as “The Ketamine Queen,” pleaded guilty in September 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 or serious bodily injury. She is scheduled to be sentenced on Feb. 25, 2026, and faces a maximum sentence of 65 years in prison.
