Overview
- A federal judge in Los Angeles sentenced Kenneth Iwamasa on May 27–28, 2026 to 41 months in prison, two years of supervised release, and a $10,000 fine as the final sentence in the case.
- Iwamasa pleaded guilty in 2024 to conspiracy to distribute ketamine resulting in death and admitted he repeatedly injected Matthew Perry, including multiple injections on the day the actor was found unconscious.
- The Los Angeles County medical examiner concluded Perry’s death was caused primarily by the acute effects of ketamine, with accidental drowning and contributing factors such as coronary disease and buprenorphine noted.
- Federal investigators uncovered a five‑person chain that supplied Perry with illegal ketamine—two doctors, a supplier known as Jasveen Sangha, an intermediary Erik Fleming, and Iwamasa—and all five defendants pleaded guilty and were sentenced.
- The case highlights how illegal diversion of ketamine outside medical oversight led to criminal liability and may prompt closer scrutiny of how prescription medicines and off‑label treatments are obtained and administered.
