Revision History

Kenneth Iwamasa, Matthew Perry's live-in personal assistant, was sentenced on May 27, 2026, to 41 months in federal prison for administering the ketamine injections that killed the actor — the final sentencing in a case that charged five people in connection with Perry's October 2023 death. The case exposed a supply chain stretching from a North Hollywood drug dealer to two licensed physicians, raising questions about the regulation of ketamine therapy, the culpability of celebrity employees, and the failure points in addiction treatment for the wealthy.
