Perry ketamine case: longtime aide gets 3.5-year sentence

Matthew Perry’s personal assistant Kenneth Iwamasa was sentenced to three years and five months in federal prison after pleading guilty to conspiracy to distribute ketamine linked to the actor’s death. Prosecutors said Iwamasa bought ketamine from a doctor and administered injections to Perry multiple times daily, with the overdose occurring in Perry’s Los Angeles home in 2023; the case branched from a multi‑defendant investigation and culminates years of prosecutorial activity surrounding Perry’s ketamine death.
