May 27 (UPI) -- Kenneth Iwamasa, a personal assistant who worked for Friends actor Matthew Perry, was to be sentenced Wednesday for injecting Perry with the dose of ketamine that killed him.

Iwamasa is the last of five people connected with Perry's death to be sentenced. Federal prosecutors said he administered the drug to Perry several times despite having no medical training.

In August, Iwamasa pleaded guilty to distributing ketamine that resulted in death or serious bodily injury. Prosecutors are seeking a sentence of three years and five months in prison, The Guardian reported.

Perry, who played Chandler Bing in the sitcom Friends, was found dead at age 54 on Oct. 28, 2023. The autopsy showed his death was caused by "the acute effects of ketamine" with contributing factors of drowning, coronary artery disease, and the effects of buprenorphine, an opioid. Perry had struggled with drug and alcohol addiction for years.
