Kenneth Iwamasa, Matthew Perry’s former personal assistant, is sentenced to 41 months in federal prison for his role in the actor’s 2023 death from a ketamine overdose. Multiple outlets report that Iwamasa pleaded guilty to conspiracy to distribute ketamine that resulted in death or serious bodily injury. Prosecutors say Iwamasa administered ketamine to Perry multiple times, including around the time he was found dead at his Los Angeles home in a hot tub. The sentencing follows the convictions or sentencing of several other individuals involved in the case, with some reporting that Iwamasa is the last person to be sentenced. Reporting also describes Iwamasa as lacking medical training and providing the drug outside a legitimate medical context. Sentencing is attributed to Judge Sherilyn Peace Garnett in the Los Angeles federal courtroom, with prosecutors seeking a sentence of about three years and five months. The final term reflects the plea and the court’s determination of Iwamasa’s involvement in supplying and administering the ketamine that contributed to Perry’s death.
