Matthew Perry's assistant sentenced to 41 months for role in the actor's death

Prosecutors said Iwamasa injected Perry with ketamine and worked with doctors to supply more than $50,000 of the drug before the actor died.

  • In a Los Angeles courtroom on Wednesday, Matthew Perry's live-in personal assistant Kenneth Iwamasa was sentenced to 41 months in prison, concluding a multi-year legal case surrounding the actor's death.
  • Prosecutors alleged that Iwamasa, lacking medical training, injected Perry with ketamine and coordinated with two doctors to supply more than $50,000 of the drug in the weeks before Perry's October 2023 death in his backyard hot tub in Los Angeles.
  • After pleading guilty in August 2024 to conspiracy to distribute ketamine causing death, Iwamasa admitted to repeatedly injecting Perry, including multiple times on the day he died; medical officials determined acute ketamine effects caused the overdose, with drowning as a contributing factor.
  • Beyond prison time, Iwamasa faces two years of supervised release and a $10,000 fine; in court, he stated he was 'horribly, horribly sorry' for illegal acts he would 'forever regret' while Perry's mother Suzanne Morrison wrote that 'We trusted a man without a conscience, and my son paid the price.'
  • All five defendants pleaded guilty, with the 'Ketamine Queen' Jasveen Sangha sentenced to 15 years in April and Dr. Salvador Plasencia to 30 months in December; Perry's sisters Caitlin Morrison and Madeline Morrison expressed conflicting views, with Caitlin stating she had 'no sympathy' while Madeline told the judge Iwamasa was 'more culpable' than Sangha.
