Matthew Perry’s family is speaking out in court filings about the assistant who admitted to giving the late actor ketamine before his death.
Ahead of Kenneth “Kenny” Iwamasa’s sentencing on Wednesday, Perry’s sisters, Madeline Morrison and Caitlin Morrison, submitted victim impact statements describing the pain they said they felt after learning more about the day the Friends star died in October 2023.
“He had injected my brother with a lethal dose of ketamine and left him in a hot tub to die,” Madeline wrote in her statement. “It is difficult to put into words the sense of betrayal I felt when I found out what Kenny had done,” she continued.
Madeline said Iwamasa had been close to Perry and spoke at his funeral, which made the revelations even harder for the family.
Matthew Perry's assistant was paid $150,000 a year to keep him clean, his mom said in a letter to the court. Instead Kenneth Iwamasa injected him with fatal doses of ketamine, prosecutors argue. He will be sentenced tomorrow. Details coming @LAmag

“Everything I believed about the day he died, everything Kenny told us, was a lie,” she wrote. “The idea that someone my brother considered family could betray him in such an unimaginable way is something I never could have conceived.” She added, “He didn’t just take my brother’s life, he tainted our final memories of saying goodbye.”
Caitlin also addressed Iwamasa’s actions in her statement, writing that she would “never know if the lethal dose of ketamine was only lethal by accident.”
Perry’s mother, Suzanne Morrison, wrote that Iwamasa’s “most important job” was to be her son’s “companion and guardian in his fight against addiction.”
