Matthew Perry's Assistant Jailed for Over 3 Years in Connection with Actor's Ketamine Death

Matthew Perry's former live-in assistant, Kenneth Iwamasa, has been sentenced to 41 months in federal prison for his involvement in the actor's ketamine overdose death. Iwamasa pleaded guilty to conspiracy to distribute ketamine resulting in death, having admitted to repeatedly injecting Perry with the drug without medical training, including the fatal dose in October 2023.

The sentencing, which also included two years of probation and a $10,000 fine, marks the conclusion of a two-and-a-half-year investigation into Perry's passing. Prosecutors highlighted Iwamasa's role as an enabler and drug supplier to the "Friends" star, despite being hired to support his sobriety.

Iwamasa is the fifth and final individual to be sentenced in connection with the case, which saw others, including a drug dealer known as the "Ketamine Queen" and former doctors, also receive penalties for their roles in supplying the illicit ketamine.
