Matthew Perry‘s personal assistant who injected the actor with the ketamine that led to his fatal overdose was sentenced Wednesday to 41 months in prison.

The assistant, Kenneth Iwamasa, pleaded guilty in 2024 to one count of conspiracy to distribute ketamine causing death. He repeatedly gave Perry the drug despite several warning signs of danger, administering the dose that killed him on Oct. 28, 2023.

The sentence puts an end to a yearslong legal saga after Perry was discovered unresponsive and floating face down in the hot tub of his Los Angeles home after becoming increasingly reliant on the drug. Four others have been charged and sentenced in connection to the death.

Iwamasa, who was paid $150,000 per year, had known Perry since 1992 and became his live-in assistant in 2022. Prosecutors said he was aware of the actor’s struggle with addiction and was warned by doctors that ketamine shouldn’t be self-administered.
