Matthew Perry’s assistant Kenneth “Kenny” Iwamasa was sentenced Wednesday to 41 months in prison for his role in Perry’s fatal ketamine overdose, according to People magazine.
Los Angeles Judge Sherilyn Peace Garnett ordered Iwamasa, 60, to pay an additional $10,000 and a $100 fine and serve two years of supervised release.
He must report to prison by July 17, according to People magazine.
Prior to sentencing, prosecutors asked Garnett to sentence Iwamasa to three years and five months in prison.
Meanwhile, Iwamasa’s lawyers said in a court filing that he was only following his employer’s orders and that his relationship with the late Perry had a “special vulnerability” in that he “couldn’t simply say no.”
In a victim impact statement, Perry’s sisters Madeline and Caitlin Morrison accused Iwamasa of “repeatedly” injecting Perry with ketamine in October 2023 and leaving him “to die” in the bathtub at his home.
They alleged that Mr. Iwamasa lied to Mr. Perry’s relatives about what happened the day Mr. Perry died at his home in Pacific Palisades, California.
Madeline also criticized Iwamasa, who spoke at Perry’s funeral in November 2023.
In a letter to the judge, Perry’s mother, Suzanne Morrison, accused Iwamasa of failing to serve as Perry’s “companion and protector in his struggle with addiction.”
“We trusted a man with no conscience, and our son paid the price,” Suzanne said.
Lisa Kallio, a former Perry employee, claimed in her own letter that Iwamasa had been driving around in Perry’s car since his death.
Mr. Perry hired Mr. Iwamasa in 2022 and paid him $150,000 a year as an assistant and lived in his home in Los Angeles.
The “Ally McBeal” actor, who battled drug addiction, was undergoing “ketamine drip therapy” until his death.
Mr Iwamasa injected Mr Perry with illegal doses of drugs “without medical training”, resulting in Mr Perry’s death at the age of 54.
Four other people have been charged in connection with Perry’s death: Dr. Mark Chavez, drug counselor Eric Fleming, “Queen of Ketamine” Jasveen Sangha, and Dr. Salvador Plasencia.
Chavez, who admitted to helping distribute ketamine to Placencia, was sentenced to eight months of house arrest in December 2025.
That same month, Placencia, who illegally supplied Perry with ketamine, was sentenced to 30 months in prison.
Convicted drug dealer Sangha, whom prosecutors dubbed the “Ketamine Queen,” was sentenced to 15 years in prison in April.
As for Fleming, he was sentenced earlier this month to two years in prison and an additional three years of supervised release for distributing the ketamine that caused Perry’s fatal overdose.
