Kenneth Iwamasa, the longtime personal assistant to the late actor Matthew Perry, has been sentenced to 41 months in federal prison for his role in the events surrounding the actor’s death in October 2023. Iwamasa, 60, had previously entered a guilty plea to the charge of conspiracy to distribute ketamine, a controlled substance that was identified by medical examiners as the primary cause of Perry’s fatal overdose.

During the legal proceedings, it was revealed that Iwamasa, who possessed no formal medical training, acted as a primary facilitator in obtaining and administering the drug. Prosecutors presented evidence showing that Iwamasa worked with various medical professionals to acquire over $50,000 worth of ketamine in the weeks preceding the tragedy. The court confirmed that Iwamasa personally injected the actor with the substance on multiple occasions, including the day he was found unresponsive at his home in Los Angeles.

At the sentencing hearing, Judge Sherilyn Peace Garnett emphasized the gravity of the situation, noting that Iwamasa was well aware of Perry’s history with substance abuse. The court specifically highlighted the recklessness of administering high doses of the drug and subsequently leaving the actor unattended, as well as attempts to conceal evidence. This sentencing marks a pivotal moment in the broader federal investigation into the network of individuals who enabled the supply of illicit substances to the late star.
