The Fatal Night: Matthew Perry’s Death
On October 28 2023, actor Matthew Perry was found unresponsive in his Los Angeles hot tub. The Los Angeles County coroner ruled the cause “acute effects of ketamine,” with drowning, coronary-artery disease and buprenorphine also listed as contributing factors. The Department of Justice (DOJ) later identified Perry’s former personal assistant, Kenneth Iwamasa, as having repeatedly injected the actor with ketamine without medical training, including multiple injections on the day of his death.
Background: Addiction, Ketamine Therapy, and Assistant’s Role
Perry had a long history of anxiety, depression and substance-use disorder. In the months before his death he pursued ketamine-infusion therapy for depression, a treatment that some physicians defend as a legitimate option when administered under supervision. Prosecutors allege that Iwamasa, instead of safeguarding Perry, arranged illegal sources of ketamine and personally administered the drug, violating medical standards.

Official Statements and Responses
The DOJ confirmed Iwamasa’s guilty plea and described his conduct as “repeatedly injecting the actor without medical training.” Federal prosecutors filed a sentencing memorandum recommending 41 months imprisonment and supervised release. Morrison thanked investigators for “relentless determination to dig out the truth” while noting that “closure” remains unattainable.
Criticism and Opposition
Morrison’s impact statement accuses Iwamasa of betraying the family’s trust and enabling Perry’s addiction. She writes that his “most important job … was to be my son’s companion and guardian in his fight against addiction.” By contrast, some medical professionals have argued that ketamine, when properly administered, can be an effective treatment for refractory depression, suggesting that the tragedy reflects misuse rather than the drug’s therapeutic potential.
Conflicting Reports and Gaps
The coroner’s report lists multiple contributing factors—ketamine, drowning, coronary-artery disease, and buprenorphine—creating ambiguity about the primary cause of death. Details of the exact dosage schedule and the full extent of the supply chain remain undisclosed, and the sentencing outcome for Iwamasa is pending.
