Matthew Perry’s live-in personal assistant entered a guilty plea in October 2023, acknowledging that “the acute effects of ketamine” were the cause of the Friends star’s death.

Kenneth Iwamasa, Perry’s assistant, was among five individuals charged with crimes relating to Perry’s death, the Department of Justice stated on August 15.

According to the Department of Justice, Iwamasa pleaded guilty to one count of conspiracy to distribute ketamine, causing death.

Iwamasa “repeatedly” injected Perry with ketamine “without medical training,” including on October 28, 2023, the day of the actor’s death, according to the Department of Justice.

The lawsuit also names “The Ketamine Queen,” Jasveen Sangha, and Dr. Salvador Plascencia as defendants. The arraignment will take place on August 15.

Sangha faces one count of conspiracy to distribute ketamine, one count of keeping drug-involved premises, one count of possession with intent to distribute methamphetamine, one count of possession with intent to distribute ketamine, and five charges of distribution of ketamine.

Plascencia faces charges of conspiring to distribute ketamine.

The accusations also included Mark Chavez, another doctor, and Erik Fleming. According to the Justice Department, Chavez will plead guilty to one count of conspiracy to distribute ketamine, while Fleming has pleaded guilty to one count of conspiracy to distribute ketamine and one count of ketamine distribution resulting in death.

Following their guilty pleas, Iwamasa and Fleming may face 15 to 25 years in jail. Chavez faces up to ten years in jail.

If found guilty, Sangha faces a required minimum of ten years in jail and a possible life sentence.

Perry, 54, died on October 28 after an accidental drug overdose. According to an autopsy, the actor died as a result of the acute effects of ketamine. Drowning, coronary artery disease, and the effects of buprenorphine, a medication used to treat opioid use disorder, all had a role.
