Kenneth Iwamasa, the personal assistant to actor Matthew Perry, has been sentenced to 41 months in prison for administering ketamine that contributed to the actor’s death in 2023. The sentencing took place in a Los Angeles court where Judge Sherilyn Peace Garnett criticized Iwamasa’s role in the events leading up to Perry’s passing, highlighting his repeated administration of the drug despite knowing the actor’s struggles with addiction.

Prosecutors stated that Iwamasa, 60, provided and injected ketamine to Perry multiple times in the weeks before the actor’s death, spending more than $50,000 on the drug in collaboration with two doctors. During Perry’s final weeks, Iwamasa reportedly found the actor unconscious on at least two occasions. At the time of Perry’s death, Iwamasa was the last person to see him alive and was the one to discover his body in the hot tub at his Hollywood residence.

Iwamasa pleaded guilty to conspiracy to distribute ketamine causing death and expressed remorse to Perry’s family during the hearing. Judge Garnett also noted that Iwamasa had repeatedly given false information to police about his involvement in the case.

Defense attorneys argued that Iwamasa was acting under Perry’s direction and that he felt unable to refuse the actor’s requests for the drug. Despite this, the judge described Iwamasa’s behavior as reckless, not only on the day of Perry’s death but throughout the period leading up to it.

Iwamasa was one of five individuals prosecuted in connection with Perry’s death. Among others, Jasveen Sangha, known as the "Ketamine Queen," was sentenced to 15 years in prison earlier this year for supplying the drug. The ongoing legal actions spotlight the broader issues surrounding substance abuse and the provision of controlled substances that played a role in the fatal incident involving the "Friends" star.
