LOS ANGELES — Suzanne Morrison, the mother of actor Matthew Perry, read a victim impact statement at the sentencing hearing for Kenneth Iwamasa in Los Angeles on May 27, 2026. Iwamasa, Perry's former personal assistant, pleaded guilty on August 7, 2024 to one count of conspiracy to distribute ketamine resulting in Perry's death.

The Department of Justice said Iwamasa conspired with Jasveen Sangha, Erik Fleming and Dr. Salvador Plasencia to obtain and distribute ketamine to Perry illegally. Sangha, 41, known as "The Ketamine Queen" of North Hollywood, was sentenced to 15 years in federal prison for running a drug trafficking business and supplying the ketamine that killed Perry. Plasencia, 42, of Santa Monica, will spend 30 months in federal prison, and Fleming, 54, received two years in prison and three years of supervised release.

Perry was found unresponsive in his hot tub on October 28, 2023, at age 54. Medical examiners determined he died from an accidental ketamine overdose. In the months before his death, Perry underwent treatments for anxiety and depression, including ketamine infusion therapy, and prosecutors said he developed a dependence on the therapy and sought additional doses.

Morrison, 82, addressed the court about Iwamasa's role as Perry's companion and guardian. "His number one responsibility was to ensure that Matthew remained what he wanted to be: drug-free," she said. "But instead of protecting Matthew, he aided and abetted illegal drug use, arranged for one source of supply and then another."

She said Iwamasa administered the drug himself. "He shot the drugs into Matthew's body, though he was not in the least qualified. He did it even though anyone could see how obviously dangerous it was. And he did it again and again."
