Ken Iwamasa, 60, the former personal assistant to late actor Matthew Perry, was sentenced to 41 months in prison after pleading guilty to conspiracy to distribute ketamine that directly caused Perry’s death on October 28, 2023. Judge Sherilyn Peace Garnett delivered the sentence in Los Angeles County, ordering Iwamasa to pay a $10,000 fine, $100 restitution, and to serve two years of supervised release after his release.

25 Lethal Injections, One Fatal Day in Pacific Palisades

According to the indictment, Iwamasa administered more than 25 ketamine injections to Perry in the days leading up to the fatal incident, including at least three shots on the day Perry was found dead in his Pacific Palisades jacuzzi. The actor’s final request,allegedly spoken moments before the last injection, was to "shoot me up with a big one." Iwamasa, who had no medical training, complied, and later left Perry briefly to run errands.. When he returned, he discovered Perry unresponsive in the hot tub, an outcome investigators linked to a lethal overdose of the dissociative anesthetic.

Conspiracy Charge and Evidence Destruction

Prosecutors presented a detailed timeline of the events leading to Perry’s death, noting that within an hour of the actor’s death, Iwamasa directed the removal and destruction of both hard‑copy and digital records that documented the supply network of ketamine and other substances. the court hearing also featured emotional statements from Perry’s family ,with his mother Suzanne Morrison and sisters Caitlin and Madeline denouncing Iwamasa and accusing him of abandoning a vulnerable person and contributing to their son’s death.

First of Five Plea Agreements in a Two‑Year Saga

Iwamasa was the first of the five people implicated in the case to secure a plea agreement in August 2024. the sentencing marks the conclusion of a legal saga that spanned more than two years and involved four other individuals linked to the actor’s drug supply chain.. The broader case continues as other members of Perry’s inner circle face ongoing legal proceedings.

Who Is the Unnamed Buyer?

While the indictment details Iwamasa’s role, it leaves unanswered who supplied the ketamine and how the supply chain was established. The prosecution rejected Iwamasa’s claim that he felt unable to refuse Perry’s demands, noting that he had previously concealed evidence of the actor’s drug use. The identity of the original supplier remains unclear , raising questions about the extent of the network and whether other parties will be charged.

What Happens After Supervised Release?

Upon release,Iwamasa will be placed under supervised release for two years, required to report to authorities by noon on July 17 to begin serving his sentence. The court’s decision to impose supervised release reflects the seriousness of the offense and the need for ongoing monitoring. It remains to be seen how the supervised release will be enforced and what conditions will be imposed.
