LOS ANGELES (CNS) - A licensed physician based in San Diego and an alleged San Fernando Valley drug dealer were arrested Thursday in connection with the death of "Friends" actor Matthew Perry, who was found dead in October in a hot tub behind his Pacific Palisades home.

A total of five defendants face federal charges, including a live-in assistant, two doctors and a woman known as the "Ketamine Queen." U.S. Attorney Martin Estrada said the defendants are part of a "broad underground criminal network" that supplied ketamine to Perry and others, and "took advantage of Mr. Perry's addiction issues to enrich themselves."

The five defendants charged in connection with Perry's death are:

  • Jasveen Sangha, 41, a.k.a. "The Ketamine Queen," of North Hollywood;
  • Dr. Salvador Plasencia, 42, a.k.a. "Dr. P," of Santa Monica;
  • Eric Fleming, 54, of Hawthorne, who pleaded guilty last week to one count of conspiracy to distribute ketamine and one count of distribution of ketamine resulting in death, admitting that he distributed the ketamine that killed Perry, prosecutors said;
  • Kenneth Iwamasa, 59, of Toluca Lake, Perry's live-in assistant, who allegedly conspired with Sangha, Fleming and Plasencia to illegally obtain ketamine and distribute it to Perry; and
  • Dr. Mark Chavez, 54, of San Diego, a physician who has agreed to plead guilty to one count of conspiracy to distribute ketamine, admitting to selling the drug to Plasencia, including ketamine that he had diverted from his former ketamine clinic.

Sangha and Plasencia are charged with one count of conspiracy to distribute ketamine. Sangha also is charged with 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 updated indictment alleges that Sangha's distribution of ketamine caused Perry's death. Plasencia is charged with seven counts of distribution of ketamine and two counts of altering and falsifying documents or records related to the federal investigation.

Doctors, assistant arrested in connection to Matthew Perry's drug overdose death

Sangha and Plasencia are expected to be arraigned Thursday at U.S. District Court in downtown Los Angeles.

"These defendants cared more about profiting off of Mr. Perry than caring for his well-being," Estrada said. "Drug dealers selling dangerous substances are gambling with other people's lives over greed."

Local and federal authorities confirmed in May that they were investigating how Perry obtained the prescription drug ketamine, which contributed to his Oct. 28 death at age 54.

The Los Angeles County Department of Medical Examiner determined the cause of death was "the acute effects of ketamine."

"Contributing factors in Mr. Perry's death include drowning, coronary artery disease and the effects of buprenorphine, used to treat opioid use disorder. The manner of death is accident," the medical examiner's office said in a statement.

Ketamine is approved by the DEA for use as an anesthetic. A nasal spray version is used to treat depression in a clinical setting, DEA Administrator Anne Milgram said.

According to the court papers unsealed Thursday, in late September, Plasencia learned that Perry, a successful actor whose history of drug addiction was well documented, was interested in obtaining ketamine. The use of ketamine requires a health care professional to monitor a patient who had been given the drug.

After learning of Perry's interest in ketamine, Plasencia contacted Chavez -- who previously operated a ketamine clinic -- to obtain ketamine to sell to Perry, prosecutors allege.

In text messages to Chavez, Plasencia allegedly discussed how much to charge Perry for the ketamine, stating, "I wonder how much this moron will pay."

Prosecutors say Perry was paying $2,000 per vial of ketamine, while his dealers were paying $12 for each vial.

Perry's 2022 best-selling memoir, "Friends, Lovers and the Big Terrible Thing," discusses his years-long struggle with addiction. The "Friends" star, who played the character Chandler Bing in the series, says he went through detox 65 times.

Last fall, Perry fell back into addiction, "and the defendants took advantage to profit for themselves," Estrada said during a press conference Thursday in downtown Los Angeles.

When doctors refused to increase his ketamine dosage, Perry turned to unscrupulous doctors, Milgram said. "Instead of do no harm, they did harm so that they could make more money," she added.

Prosecutors contend that last September and October, Plasencia distributed ketamine to Perry and Iwamasa without a legitimate medical purpose on at least seven occasions. He taught Iwamasa how to inject Perry with ketamine, selling the drug to Iwamasa to administer to the actor, including once inside a car parked in a Long Beach parking lot, prosecutors allege.

Plasencia knew Iwamasa had never received medical training and knew little, if anything, about administering or treating patients with controlled substances, court papers allege.

Beginning in mid-October, Iwamasa also allegedly began obtaining ketamine for Perry from Fleming and Sangha. After discussing prices with Iwamasa, Fleming coordinated drug sales with Sangha, and brought cash from Iwamasa to Sangha's stash house in North Hollywood to buy vials of ketamine. Sangha has distributed ketamine and other illegal drugs from her stash house in North Hollywood since at least 2019, according to the U.S. Attorney's Office.

Sangha was aware of the danger of ketamine: In August 2019, Sangha sold the anesthetic to victim Cody McLaury in the hours before his death. The indictment alleges that Sangha nonetheless continued to sell ketamine from her house.

Using the Plasencia-provided instructions and syringes, Iwamasa injected Perry with the ketamine that was sold to him by Fleming and Sangha, including on Oct. 28, when Perry died at his Pacific Palisades home after receiving multiple injections. Plasencia allegedly sold the ketamine to Iwamasa despite being informed at least one week earlier that Perry's ketamine addiction was spiraling out of control, prosecutors say.

After Perry's death was reported in the news, Sangha texted Fleming, "Delete all our messages," court papers show.

After the actor's death, federal agents and detectives with the LAPD executed search warrants at Sangha's home, where they found evidence of drug trafficking, including about 79 vials of ketamine, roughly 3.1 pounds of orange pills containing methamphetamine, psilocybin mushrooms, cocaine, and prescription drugs that appeared to be fraudulently obtained.

If convicted of all charges, Sangha would face a sentence between 10 years and life imprisonment. Plasencia would face up to 10 years in federal prison for each ketamine-related count and up to 20 years in federal prison for each records falsification count, prosecutors said.

Iwamasa and Fleming will face up to 15 years and 25 years, respectively, when they are sentenced in their federal cases.

Chavez has been charged pursuant to a plea agreement and will be arraigned on Aug. 30. At sentencing, Chavez will face up to 10 years in federal prison, according to the U.S. Attorney's Office.

Los Angeles Police Department Chief Dominic Choi said his department "is committed to investigating all cases like this," regardless of a victim's fame or economic status.
