Kenneth Iwamasa, the live-in personal assistant to "Friends" actor Matthew Perry, is scheduled to be sentenced Wednesday for his role in Perry's fatal ketamine overdose on October 28, 2023. Prosecutors are seeking a prison term of three years and five months for Iwamasa, who pleaded guilty to conspiracy to distribute ketamine resulting in death.

Iwamasa, 60, was paid $150,000 annually and administered the ketamine injections that proved fatal to Perry at his Los Angeles home. According to court filings, Iwamasa left Perry alone after the injections to run errands and returned to find the actor dead in his jacuzzi. The Los Angeles County Medical Examiner determined ketamine was the primary cause of death, with drowning as a secondary cause.

Perry's family has expressed particular anger toward Iwamasa, whom they had trusted to help the actor maintain his sobriety. In victim impact statements, Perry's mother Suzanne Morrison wrote that the family had known Iwamasa for decades and were relieved when Perry hired him in 2022 during his ongoing struggles with addiction. "Matthew trusted Kenny. We trusted Kenny," she wrote, adding that his primary responsibility was to be her son's "companion and guardian in his fight against addiction."

Iwamasa became the first of five people to reach a plea deal in connection with Perry's death and served as a key witness against his co-defendants. Court documents reveal he had been giving Perry six to eight ketamine injections daily in the final days of the actor's life. On the day Perry died, the actor reportedly told Iwamasa to "shoot me up with a big one."

Initially, Iwamasa omitted ketamine from the list of medications he provided to police following Perry's death and said nothing about the injections. He only began admitting his role after investigators served a search warrant on the house in January 2024. Iwamasa worked with middleman Erik Fleming to obtain drugs from dealer Jasveen Sangha, texting Fleming as "Alfred here batmans butler."

Perry, who died at 54, gained international fame playing Chandler Bing on NBC's "Friends," which aired from 1994 to 2004. His death marked the end of a long public battle with addiction that had affected him throughout his career and personal life.
