People Editorial Guidelines Updated on August 16, 2024 03:22PM EDT On the day of his death, Matthew Perry asked his assistant to inject him with a large dose of ketamine. Perry died on Oct. 28, 2023. At 8:30 that morning, the Friends star’s assistant, Kenneth Iwamasa, injected him with a first dose of ketamine, according to a plea agreement Iwamasa made with the Department of Justice. At 12:45 p.m., Iwamasa again injected Perry while the actor watched a movie in his home. According to the plea agreement, Perry asked for yet another dose 40 minutes after the second. “Shoot me up with a big one,” Perry told his assistant, and asked him to get his hot tub ready. The third dose was administered while Perry was either near or in his jacuzzi, according to the agreement. Iwamasa then left the home to run errands. When he returned, he found Perry dead, face down in the jacuzzi. Iwamasa was one of five defendants charged by the justice department in connection with Perry’s death, which was the result of “acute effects" of ketamine, according to his autopsy report.
