Matthew Perry's Assistant Jailed for Over Three Years in Ketamine Death

Matthew Perry's former live-in assistant, Kenneth Iwamasa, has been sentenced to three years and five months in prison for his central role in the actor's ketamine-related death. Iwamasa pleaded guilty in August 2024 to conspiracy to distribute ketamine causing death, marking the culmination of a two-and-a-half-year investigation and prosecution.

Prosecutors revealed that Iwamasa repeatedly administered ketamine injections to Perry without medical training, including multiple doses on October 28, 2023, the day the "Friends" star was found deceased in his hot tub. He also allegedly purchased illicit ketamine from other sources and took steps to destroy evidence after Perry's passing. Iwamasa was among five individuals charged in connection with Perry's overdose, with others, including doctors and a drug dealer, also receiving sentences for their involvement.
