Matthew Perry’s personal assistant Kenneth Iwamasa, who helped to administer fatal shots of ketamine to the “Friends” actor, was sentenced to three years and five months behind bars.

Iwamasa looked stoic and wore a grey suit with a white shirt and grey tie with long grey hair as his fate was revealed by Judge Sherilyn Peace Garnett in LA federal court Wednesday. She also sentenced him to two years of probation and fined him $10,000.

Iwamasa, 60, addressed Perry’s family when given the chance to speak.

“I’m so sorry to all of you. Matthew loved you,” he said. He added he would take the mistake to his grave.

Perry’s stepfather, “Dateline NBC” correspondent Keith Morrison, and Perry’s estate manager both gave very dramatic victim impact statements during the hearing — Iwamasa appeared to be on the verge of tears as Morrison spoke.

“You were part of the family,” Morrison said, before adding: “You could have called someone. You kept injecting him.”

Morrison later added: “You were living a dandy life. Like a king.”

Prosecutors had asked the judge to sentence Iwamasa to three years and five months behind bars after he pled guilty to one count of conspiracy to distribute ketamine resulting in death in August 2024. Iwamasa cooperated with investigators throughout their investigation into the actor’s death.

Iwamasa marks the last person in the actor’s death saga to be sentenced — he will be taken into custody on July 17 to begin his sentence.

Perry’s mom, Suzanne, was also in attendance for the sentencing.

Suzanne submitted an emotional victim impact statement, reminding the court of what she saw on the tragic October 2023 night her son died at the age of 54. “Matthew trusted Kenny. We trusted Kenny,” she said.

“Kenny’s most important job — by far — was to be my son’s companion and guardian in his fight against addiction. We trusted a man without a conscience, and my son paid the price.”

“One night he was just a body, lying all but naked on the cold damp grass of his backyard. Helicopters circled overhead, eager for a glimpse of my dead little boy,” she wrote in the letter obtained by The California Post.

“I stood out on the street in the cold and begged for a blanket to cover him. Impossible, of course,” she added.

She then described her horrific trip to the morgue to see her once vibrant son, “He had been bathed and dressed and he looked almost beautiful and somehow relieved, like a gladiator who has finally earned his rest.” Morrison wrote.

Erik Fleming, 56, had pleaded guilty in connection with Perry’s overdose and was sentenced to two years on May 12.

Fleming, a former Hollywood producer and director, introduced Perry to “Ketamine Queen” Jasveen Sangha two weeks before the actor’s shocking death.

Sangha was sentenced last month to 15 years behind bars for her role in the actor’s fatal overdose.

Sangha told the court she took full responsibility for her crimes, adding she had the “rug of life ripped out” from under her.

At Sangha’s April 8 sentencing, Perry’s mother Suzanne and stepfather Keith Morrison appeared in court to address the convicted drug dealer.

“I feel bad for you, Miss Sangha. I don’t hate you. … You are a drug dealer,” Morrison told the court, fighting back tears.

He called Perry a brilliant and talented man, adding he should have “had another act.”

Those convicted over Matthew Perry’s death

  • Jasveen Sanga: Drug dealer accused of supplying ketamine, 15 years’ prison.
  • Mark Chavez: Pleaded guilty to helping supply ketamine through another physician, eight months home detention
  • Dr. Salvador Plasencia: 2.5 years in prison for pleading guilty for supplying ketamine to Perry.
  • Erik Fleming: Two years prison for delivering the ketamine which led to Perry’s overdose death.
  • Kenneth Iwamasa: Perry live-in assistant who admitted injected him with Ketamine, the final person to be sentenced.

Mark Chavez, 55, was hit with eight months of home confinement by a Los Angeles federal judge on December 16 after he admitted in October to supplying 22 vials and nine lozenges of powerful medical anesthesia ketamine to the actor — despite knowing his struggles with drug addiction.

Dr Salvador Plasencia, 43, who was sentenced to two and a half years on December 3 for his role in Perry’s overdose.

Plasencia told Chavez how he once injected Perry “in the back seat of a car parked at a public parking lot of an aquarium in Long Beach, Calif.,” and Chavez “reprimanded Plasencia” for “dosing him” in a public place where kids were, prosecutors wrote.
