Overview
- Kenneth Iwamasa was sentenced to 41 months in federal prison on Wednesday, May 27, 2026, was ordered to pay roughly $10,100 and must report to custody by a mid‑July surrender date.
- He pleaded guilty in August 2024 to a conspiracy charge tied to distributing ketamine that resulted in death and cooperated with prosecutors by providing evidence used against other defendants.
- Court records say Iwamasa injected Perry more than 25 times in the days before the October 28, 2023 death, including three doses on the day Perry was found, and the medical examiner ruled acute ketamine intoxication the primary cause with drowning a contributing factor.
- Prosecutors allege he tried to destroy physical and digital evidence soon after Perry’s death by discarding vials and syringes, changing passwords and deleting data, and family statements and a longtime PR agent accused him of enabling and betraying Perry.
- The Iwamasa sentence completes convictions of five people tied to Perry’s ketamine supply chain, from dealers to two physicians, and underscores prosecutors’ focus on illegal access and non‑medical administration of ketamine.
