A somber chapter has closed in the tragic story of Matthew Perry’s death. His former live-in assistant, Kenneth Iwamasa, has been sentenced to over three years in prison for his role in injecting the beloved ‘Friends’ actor with ketamine, which prosecutors say led to his death.
The Sentencing Details
On Wednesday, May 27, 2026, Iwamasa received a sentence of 41 months (over three years) behind bars. He was also ordered to pay $10,000 and $100 in fines and will face two years of supervised release after his prison term. Iwamasa is expected to surrender to authorities by July 17.
This sentencing follows Iwamasa’s guilty plea in August 2024 to conspiracy to distribute ketamine resulting in death. Prosecutors alleged that Iwamasa administered at least three shots of ketamine to Perry on October 23, 2023. The 54-year-old actor was tragically found unresponsive in his jacuzzi at his Los Angeles home just days later, on October 28, 2023.
The Wider Conspiracy Uncovered
The investigation into Perry’s death revealed a broader network involved in supplying the ketamine. Jasveen Sangha, dubbed the “Ketamine Queen,” was identified as the supplier. She pleaded guilty in September 2025 to charges including maintaining a drug-involved premises and distributing ketamine, with one count specifically resulting in death or serious bodily injury. Sangha was sentenced to 15 years in federal prison in April 2026.
In addition to Iwamasa and Sangha, three other individuals pleaded guilty in connection to Perry’s death. This includes Perry’s friend Erik Fleming, accused of distributing drugs to Iwamasa, and doctors Mark Chavez and Salvador Plasencia. Chavez received 8 months of home detention and 3 years of supervised release, while Plasencia was sentenced to 30 months in federal prison. Fleming was sentenced to 24 months in prison in early May 2026.
Family’s Grief and Assistant’s Apology
Following Iwamasa’s sentencing, Perry’s stepfather, Keith Morrison, expressed his deep pain. “I’m glad it’s done, but to say I’m angry is an understatement,” Morrison stated. He highlighted that Iwamasa had been entrusted with calling Perry’s parents if he struggled with substance abuse, but instead, Morrison believes Iwamasa “controlled him by the use of ketamine.”
Addressing the family, Iwamasa offered a tearful apology: “I’m so sorry to all of you. I’m just so sorry. I’ve done illegal acts that I will forever regret. I will take that to my grave.”
The autopsy report revealed that the acute effects of ketamine were the primary cause of Perry’s death, with contributing factors including drowning, coronary artery disease, and the effects of buprenorphine. The legal proceedings aim to bring a measure of accountability for the events that led to the beloved actor’s untimely passing.
