Overview
- U.S. District Judge Sherilyn Peace Garnett sentenced Kenneth Iwamasa to 41 months in prison on Wednesday, May 27, 2026, plus two years of supervised release and a $10,000 fine.
- Iwamasa pleaded guilty in August 2024 to conspiracy to distribute ketamine resulting in death and cooperated with prosecutors, whose recommended term matched the sentence he received.
- Prosecutors said Iwamasa repeatedly injected Perry with ketamine, including multiple injections on the day the actor was found unresponsive, and the Los Angeles County medical examiner ruled the acute effects of ketamine the primary cause of death.
- Recent court filings reported before sentencing accused Iwamasa of directing others to destroy ketamine vials and syringes, shred records, and delete or alter digital files, allegations the court considered in imposing punishment.
- The case concluded with five defendants sentenced for roles in an illicit ketamine supply chain and highlights concerns about off‑label ketamine use, how caregivers can enable dependence, and questions about oversight of controlled substances.
