AceShowbiz - Matthew Perry’s mother, Suzanne Perry, has openly condemned her late son’s former assistant, Kenneth Iwamasa, holding him responsible for the actor’s tragic passing. In a heartfelt victim impact statement submitted ahead of Iwamasa’s sentencing, Suzanne expressed her grief and anger, stating that Iwamasa “killed my son.”

Kenneth Iwamasa faces up to 15 years in prison following accusations that he repeatedly injected Matthew Perry with ketamine without any medical training. This included the day of Perry’s death on October 28, 2023, when the actor was found deceased at age 54. The Department of Justice revealed that Iwamasa administered a large dose of ketamine that ultimately caused Perry’s death.

The actor was discovered in his hot tub by Iwamasa after the assistant returned from running errands. According to Iwamasa’s plea agreement, he gave Perry a significant injection of ketamine. The official cause of death was listed as the acute effects of ketamine, and Iwamasa pled guilty to one count of conspiracy to distribute ketamine causing death.

With sentencing scheduled for May 27, Suzanne Perry made it clear that she holds Iwamasa accountable for the loss of her son. In her statement, she described how she and her family had trusted Iwamasa deeply, having known him and her son for 25 years.

“Matthew trusted Kenny. We trusted Kenny. Kenny’s most important job – by far – was to be my son’s companion and guardian in his fight against addiction,” she wrote. Suzanne emphasized that Iwamasa’s primary responsibility was to ensure Matthew Perry remained drug-free, and that support was always available if he felt overwhelmed.

However, the letter pointed out that instead of protecting Perry, Iwamasa enabled and facilitated illegal drug use. Suzanne accused him of arranging drug supplies and administering ketamine injections himself, despite lacking any medical qualifications. She said, “He shot the drugs into Matthew’s body, though he was not in the least qualified. He did it even though he could see, anyone could have seen, it was so obviously dangerous. And he did it again and again.”

Following Perry’s death, Suzanne described how Iwamasa maintained an unsettling presence, sending her songs and even drawing a map to help her navigate the cemetery where her son was buried. She also alleged that he insisted on speaking at Perry’s funeral, clinging to her as if he were somehow the “good guy” who tried to save her son.

“We trusted a man without a conscience, and my son paid the price,” Suzanne concluded. Her letter ended on a somber note, acknowledging the enduring pain she will carry for the rest of her life.

Investigations revealed that Iwamasa was among five individuals charged with conspiracy to distribute ketamine to Perry. One of those charged, Jasveen Sangha—dubbed the “Ketamine Queen”—was sentenced in April 2026 to 15 years in federal prison along with three years of supervised release.

Sangha pleaded guilty in September 2025 to multiple counts, including maintaining a drug-involved premises and distributing ketamine that resulted in death or serious injury. Authorities stated that she sold approximately 50 vials of ketamine to Perry for $11,000, including the batch linked to his fatal overdose.

The case continues to highlight the devastating consequences of drug abuse and the roles played by those around vulnerable individuals. Suzanne Perry’s emotional letter underscores the tragic loss of a beloved son and the lasting impact on his family as the legal process moves forward.
