  "textContent": "\n\n\nMatthew Perry's long-time personal assistant has been jailed for his role in the Friends star's fatal ketamine overdose.\n\nUS District Judge Sherilyn Peace Garnett sentenced Kenneth Iwamasa to 41 months in Cyprus in federal court in Los Angeles on Wednesday, matching the punishment requested by prosecutors.\n\n###\n\n\n\n\nMr Iwamasa, 60, pleaded guilty in 2024 to conspiracy to distribute ketamine causing death.\n\nHe admitted injecting Mr Perry with the dissociative anaesthetic three times on October 28 2023, the day the actor died.\n\n###\n\n\n\n\nTRENDING\n\nStories\n\nVideos\n\nYour Say\n\n###\n\n\n\n\nThe pair had been friends for 25 years.\n\nMr Perry was found unresponsive in his hot tub at his home and was pronounced dead aged 54.\n\nThe actor's family submitted emotional victim impact statements ahead of the sentencing, describing a deep sense of betrayal over Mr Iwamasa’s actions.\n\n“It is difficult to put into words the sense of betrayal I felt when I found out what Kenny had done,” wrote Perry’s half-sister Madeline Morrison.\n\n###\n\n\n\n\n###\n\n\n\n\n###\n\n\n\n\n“The idea that someone my brother considered family could betray him in such an unimaginable way is something I never could have conceived.”\n\nMs Morrison said Mr Iwamasa appeared “manic and unsettled” when the family visited Mr Perry’s home to select burial clothes, allegedly giving unsolicited explanations about what had happened.\n\n“In reality, he was trying to distract us from the truth: that he had injected my brother with a lethal dose of ketamine and left him in a hot tub to die,” she stated.\n\nA post-mortem examination concluded that Mr Perry died from the acute effects of ketamine.\n\n### LATEST DEVELOPMENTS\n\n\n\n\n  * Matthew Perry's assistant jailed after admitting he injected Friends star with ketamine before death\n  * John Cleese 'delighted' as he announces exciting Monty Python return\n  * Harriet Cowan pays tribute to Clarkson's Farm as she speaks out on Farm-Fest amid controversy\n\n\n\n###\n\n\n\n\n###\n\n\n\n\nDrowning, coronary artery disease and the presence of buprenorphine, a medication used to treat opioid addiction, were listed as contributing factors.\n\nMr Iwamasa also admitted to administering ketamine injections to Mr Perry on previous occasions despite having no medical training.\n\nMr Perry’s mother Suzanne Morrison also submitted a written statement to the court.\n\nMembers of both families attended the hearing.\n\n###\n\n\n\n\n###\n\n\n\n\nThe ketamine that killed Mr Perry was supplied through Jasveen Sangha, a North Hollywood drug dealer known as the “Ketamine Queen”.\n\nMs Sangha was sentenced to 15 years in prison in April after admitting selling the fatal dose.\n\nProsecutors said Ms Sangha and Mr Perry associate Erik Fleming sold 51 vials of ketamine to the actor in October 2023, which were later passed to Mr Iwamasa.\n\n###\n\n\n\n\n###\n\n\n\n\nTwo doctors were also sentenced in connection with the case.\n\nSalvador Plasencia, who briefly treated Mr Perry, received a 30-month prison sentence, while former ketamine clinic operator Mark Chavez was sentenced to eight months of home confinement.\n\n###\n\n\n\n\n\n\n\n\n\n\n**Our Standards: The GB News Editorial Charter**",
