Overview
- U.S. District Judge Sherilyn Peace Garnett sentenced Kenneth Iwamasa to 41 months in prison and fined him $10,000 on May 27, 2026 for obtaining and injecting Matthew Perry with ketamine, including the fatal dose.
- Iwamasa pleaded guilty in August 2024 to one count of conspiracy to distribute ketamine resulting in death and serious bodily injury, and he is the fifth and final defendant to be sentenced in the federal case.
- Prosecutors say the investigation uncovered a multi‑actor supply chain involving a primary dealer and at least two physicians who provided or enabled non‑prescribed ketamine for Perry outside normal medical channels.
- Perry’s family delivered emotional victim impact statements at sentencing, with relatives condemning defendants for exploiting his addiction and saying the punishments fall short of the harm caused.
- The case has raised questions about oversight of off‑label ketamine use, accountability for medical providers who enable illicit supplies, and possible policy or enforcement changes to curb similar networks.
