Assistant in Matthew Perry Ketamine Death Sentenced to 41 Months

Matthew Perry’s live-in assistant, Kenneth Iwamasa, was sentenced to 41 months in federal prison after pleading guilty to conspiring to distribute ketamine that contributed to the actor’s death in October 2023; prosecutors said he obtained, administered, and concealed ketamine doses for Perry, while Perry’s family condemned him as a “monster.” Co-defendants in the case received shorter or longer penalties, including a 15-year sentence for the “Ketamine Queen” Sangha and prison terms for others, as Perry’s death was ruled an acute ketamine overdose.
