When the world learned that Matthew Perry, beloved for his role as Chandler Bing on Friends, died in October 2023, the shock was compounded by a startling revelation from his own family. In a victim‑impact statement filed ahead of the sentencing of Perry’s former personal assistant, Kenneth “Kenny” Iwamasa, Perry’s sisters, Madeline and Caitlin Morrison, accused Iwamasa of repeatedly injecting their brother with a lethal dose of ketamine and then leaving him unattended in a hot tub to die.
What the Morrison Sisters Alleged
According to the court documents obtained by Page Six, Madeline Morrison described the betrayal as “unimaginable.” She wrote that Iwamasa had been “manic and unsettled” in the days leading up to Perry’s funeral and that his behavior on the day of the actor’s death was nothing short of treacherous. The sisters claim that Iwamasa told them a completely different version of events than what actually occurred, effectively covering up his role in the tragedy.
Madeline’s statement reads, in part:
“He had injected my brother with a lethal dose of ketamine and left him in a hot tub to die. Everything I believed about the day he died — everything Kenny told us — was a lie. The idea that someone my brother considered family could betray him in such an unimaginable way is something I never could have conceived.”
Caitlin Morrison echoed similar sentiments, noting that she would never know whether the dose was truly lethal because Iwamasa’s actions had obscured the facts. Both sisters emphasized the emotional damage caused by Iwamasa’s alleged deception, saying it tainted their final memories of saying goodbye to their brother.
Details of the Alleged Crime
The prosecution alleges that on the night of October 28, 2023, Iwamasa administered multiple injections of ketamine to Perry at the actor’s Pacific Palisades home. Ketamine, a dissociative anesthetic, can be fatal in high doses, especially when combined with other substances or when the individual is in a vulnerable state. After the injections, Iwamasa allegedly left Perry in a hot tub, failing to provide medical assistance or call emergency services.
When Perry’s sister Madeline arrived at the home, she discovered her brother unresponsive in the water. Emergency responders were eventually called, but by then Perry had already succumbed to the drug’s effects. The autopsy later confirmed that a high concentration of ketamine was present in Perry’s system, supporting the family’s claim that the drug played a central role in his death.
In addition to the criminal charges of homicide, Iwamasa faces accusations of falsifying statements to Perry’s family and to law‑enforcement officials. The sisters allege that he deliberately misled them about the timeline of events, the dosage administered, and his own whereabouts during the critical moments after the injections.
Legal Proceedings and Potential Sentencing
Iwamasa’s case is now moving toward sentencing. While the exact charges have not been publicly disclosed in full, the victim‑impact statements suggest that the court is considering a serious felony count, potentially second‑degree murder or manslaughter, depending on the jurisdiction’s statutes regarding drug‑related deaths.
Victim‑impact statements like those submitted by the Morrison sisters are a crucial part of the sentencing phase. They give the judge insight into the broader consequences of the crime beyond the immediate loss of life. In this case, the sisters highlighted not only the loss of their brother but also the psychological trauma of learning that someone they trusted had deliberately contributed to his death.
The sentencing could result in a lengthy prison term, especially if the prosecution can prove that Iwamasa acted with malicious intent. California law typically imposes up to 27 years to life for second‑degree murder, while manslaughter carries a lesser, though still substantial, range.
Public Reaction and Media Coverage
The revelations have reignited discussions about the responsibilities of personal assistants and caretakers for high‑profile individuals. Many fans expressed outrage on social media, demanding accountability and transparency from those who work closely with celebrities. The case also sparked renewed interest in the dangers of ketamine misuse, a drug that has seen a surge in both medical and recreational contexts in recent years.
Entertainment outlets, including Page Six, The Hollywood Reporter, and Variety, have covered the story extensively, often quoting the sisters’ statements verbatim. The narrative of betrayal—an assistant who was considered “family” turning on his employer—has resonated deeply with the public, adding a layer of tragedy to an already heartbreaking loss.

Frequently Asked Questions
What exactly is ketamine and why is it dangerous?
Ketamine is a dissociative anesthetic used medically for anesthesia and, more recently, for treatment‑resistant depression. In high doses, it can cause respiratory depression, loss of consciousness, and death, especially when combined with other depressants or when administered without medical supervision.
Was Matthew Perry known to use ketamine before his death?
There have been reports of Perry’s past struggles with substance abuse, but no definitive public record confirming regular ketamine use. The autopsy revealed a significant amount of the drug in his system at the time of death, suggesting an acute overdose.
What charges could Iwamasa face?
Potential charges include second‑degree murder, manslaughter, and falsifying statements to law enforcement. The exact charge will depend on the prosecutor’s assessment of intent and the evidence presented at trial.
How can families protect themselves from similar betrayals?
Hiring qualified, background‑checked professionals and establishing clear protocols for medical emergencies are essential. Regular check‑ins by independent parties can also help ensure that caretakers act in the best interest of those they serve.
As the legal process unfolds, the Morrison sisters hope that the truth will finally be acknowledged and that their brother’s memory will be honored without the shadow of betrayal. The case serves as a stark reminder that trust, especially in vulnerable moments, must be earned and never taken for granted.
