Matthew Perry Death Case Update: Kenneth Iwamasa, 60, the longtime personal assistant to the Friends star, has been sentenced to 41 months in prison for his involvement in the ketamine overdose death of the actor. Iwamasa is the final accused to be sentenced in the death case linked to Perry’s death in October 2023.
Perry was found dead in his hot tub in Los Angeles on October 28, 2023. He was 54.

In August 2024, Iwamasa pleaded guilty to one count of conspiracy to distribute the drug.
On May 27, 2026, he was sentenced to 41 months (roughly 3.5 years) in federal prison. He was also sentenced to two years of supervised release and ordered to pay a $10,000 fine. He has to report to prison on July 17.
Judge Sherilyn Peace Garnett, while announcing the sentence, noted that Iwamasa knew about Perry's struggle with addiction, and he hid the evidence after the actor's death.
As per BBC, in the courtroom, Iwamasa told the actor's family, "I'm so sorry to all of you. I'm just so sorry to have done illegal acts that I will forever regret. I will take it to my grave."
"I hope I'll be a cautionary tale to someone who's in my position to make better choices."
He also offered the family his condolences.
Iwamasa admitted to repeatedly injecting Perry with ketamine, including administering multiple injections on the day Perry died.
"You were privy to his trouble with addiction," Judge Garnett told Iwamasa ahead of sentencing. "You knew he should not have used ketamine at the amount he did."
