Overview
- Kenneth Iwamasa pleaded guilty in August 2024 to one count of conspiracy to distribute ketamine causing Matthew Perry’s death and agreed to cooperate with prosecutors.
- Federal filings say Iwamasa repeatedly injected Perry with ketamine without medical training, including administering multiple injections on October 28, 2023 when the actor died from the acute effects of ketamine.
- Perry’s mother Suzanne Morrison and other family members filed victim impact statements that accuse Iwamasa of betraying the family’s trust and enabling the addiction that killed Perry.
- Iwamasa’s defense asks for mercy by saying he acted at Perry’s direction and could not ‘simply say no,’ while prosecutors have reported a recommendation of roughly 41 months in prison plus supervised release.
- Iwamasa’s sentencing is scheduled for May 27, 2026 and follows earlier guilty pleas and sentences for co‑defendants, a sequence that has raised questions about non‑medical ketamine use and how caregiver relationships can enable dangerous drug access.
