June 17, 2025 -- A Santa Monica doctor charged in connection with the overdose death of actor Mathew Perry pleaded guilty Monday to four counts of distribution of Ketamine.

Dr. Salvador Plasencia, a.k.a. “Dr. P,” faces up to 40 years in prison after a plea agreement filed in the U.S. District Court for the Central District of California, according to USA TODAY, which obtained a copy of the agreement.

"The agreement anticipates a prison sentence in the range of 15-21 months, though the sentence will be up to the judge," according to the national newspaper.

Plasencia was one of five defendants indicted last August in the October 28, 2023 death of Perry, who died in the hot tub of his Pacific Palisades home from accidental drowning caused by an overdose of ketamine, a general anesthetic.

In the 18-count superseding indictment, Plasencia was charged with seven counts of distribution of ketamine and two counts of "altering and falsifying documents or records related to the federal investigation."

The Santa Monica doctor learned the month before Perry's death that the successful actor, who had a well-documented history of drug addiction, was interested in obtaining ketamine, according to the indictment.

Plasencia contacted Dr. Mark Chavez of San Diego, who previously operated a ketamine clinic, to obtain the drug to sell to Perry.

In text messages, Plasencia discussed with Chavez how much to charge Perry, stating, “I wonder how much this moron will pay” and “Lets [sic] find out,” according to the indictment.

As part of the plea agreement, Plasencia acknowledges that he "knowingly distributed ketamine" to Perry before his 2023 death, according to the USA TODAY article.

He also acknowledges that he behaved in a manner "outside the scope of professional practice," and that the drug distribution lacked "a legitimate medical purpose," the paper reported.

Three of the five other defendants, including Chavez, had agreed to plead guilty to one count of conspiracy to supply ketamine.

The other defendant, Jasveen Sangha, a.k.a. “The Ketamine Queen,” of North Hollywood, has been charged with possessing and distributing methamphetamine and ketamine and is scheduled to go on trial in August.
