Matthew Perry's Assistant Gets 41 Months in Prison

Assistant Sentenced in Matthew Perry Ketamine Death

Kenneth Iwamasa, the personal assistant who injected Matthew Perry with the fatal dose of ketamine, was sentenced to 41 months in prison on Wednesday, May 27, 2026. The sentencing took place in a Los Angeles court, marking the conclusion of a case that has drawn significant public attention.

Fifth Guilty Party in Perry's Death

Iwamasa became the fifth individual found guilty in connection with the death of the beloved Friends star. Perry was found unresponsive in the bathtub of his Los Angeles home in October 2023. The assistant's role in administering the drug was a key factor in the court's decision.

Previously sentenced in the case were a drug middleman, who received a two-year prison term, the so-called "Ketamine Queen", who was sentenced to 15 years, and a doctor who allegedly supplied the ketamine. These sentences reflect the severity of the illegal drug network that contributed to Perry's overdose.

Courtroom Statements and Apology

Before the sentencing, Iwamasa reportedly stated that Perry had instructed him to inject the drug. When Iwamasa returned to the house, he found Perry already dead. In court, Iwamasa expressed deep remorse: "I am so sorry to all of you. I'm just so sorry to have done illegal acts I will forever regret. I will take that to my grave."

Perry's stepfather, however, blamed Iwamasa for failing to inform the family that the actor had become addicted to ketamine. He accused the assistant of choosing to live "like a king" inside Perry's home instead of seeking help for the actor's addiction.

Impact and Aftermath

The case has highlighted the dangers of ketamine abuse and the responsibilities of those close to individuals struggling with addiction. Perry's death has sparked conversations about the need for better support systems and oversight in managing prescription drugs. The sentencing serves as a reminder of the legal consequences for those involved in the illegal distribution and administration of controlled substances.
