In searing victim impact statements submitted ahead of the May 27 sentencing of Kenneth Iwamasa, Perry's longtime personal assistant, two of the Friends star's half-sisters described a betrayal so profound it felt like losing their brother all over again.
Iwamasa, 60, pleaded guilty in 2024 to one count of conspiracy to distribute ketamine causing death, after admitting he had injected Perry with the powerful dissociative anesthetic on multiple occasions, including three times on the day the actor died in his hot tub in October 2023. Perry was 54. Prosecutors are seeking a sentence of 41 months in prison.
Madeline Morrison, the youngest of Perry's half-sisters, wrote that Iwamasa, a friend of the family for 25 years, had systematically deceived them in the immediate aftermath of the actor's death. She recalled visiting her brother's home to select his burial clothes and noticing how agitated and evasive Iwamasa seemed, repeatedly volunteering his account of events without being prompted.
"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 wrote. "Everything I believed about the day he died, everything Kenny told us, was a lie."
Madeline added that Iwamasa's insistence on speaking at Perry's funeral now feels like "a cruel joke I still struggle with."
Her sister Caitlin Morrison, who serves as executive director of the Matthew Perry House, was equally unsparing. "I have no sympathy for Kenny Iwamasa," she wrote, adding that she would never know whether the lethal dose was accidental. "But I know that when Kenny left the house, he was either escaping from something he knew he had done or willfully abandoning a vulnerable person in a dangerous situation."
Perry's mother, Suzanne Morrison, also submitted a letter thanking investigators for their determination in uncovering the truth.
