The Fatal Night and Iwamasa’s Involvement
On October 28 2023, actor Matthew Perry was found dead in the jacuzzi of his Los Angeles home. The Los Angeles County Medical Examiner ruled ketamine the primary cause of death, with drowning listed as a secondary factor. Court filings indicate that Perry’s live-in personal assistant, Kenneth Iwamasa, injected Perry with ketamine multiple times that day, including a dose after Perry’s request, “Shoot me up with a big one.” Iwamasa left the residence to run errands and returned to discover Perry unresponsive.
Background: Perry’s Addiction and Hiring of a Live-In Assistant
Perry publicly acknowledged a decades-long struggle with substance abuse. In 2022 he hired Iwamasa, a longtime acquaintance, as a live-in personal assistant with an annual salary of $150,000. Prosecutors say the role expanded beyond household duties to include obtaining, storing, and administering ketamine, effectively acting as an untrained medical provider during Perry’s final weeks.
Key Figures and Legal Roles
- Kenneth Iwamasa – assistant, pleaded guilty to conspiracy to distribute ketamine resulting in death.
- Dr. Salvador Plasencia – physician who supplied ketamine and instructed Iwamasa on injection technique.
- Erik Fleming – middleman who facilitated drug acquisition; sentenced to two years.
- Jasveen Sangha – dealer dubbed “Ketamine Queen,” sentenced to fifteen years.
- Martin Estrada – former U.S. attorney for the Central District of California, overseeing the prosecution.
- Suzanne Morrison, Caitlin Morrison, Madeline Morrison – Perry’s mother and sisters, who submitted victim-impact statements.
Legal Proceedings and Prosecutors’ Request
Iwamasa entered a guilty plea in August 2024 and became the government’s principal witness against the remaining defendants. Federal prosecutors have asked the court to impose a 41-month (three years and five months) prison term, noting that the sentence exceeds that of the physician who sold the drug but is shorter than the dealer’s fifteen-year term. The sentencing hearing is scheduled for Wednesday, May 26 2026.
Family Impact Statements
Suzanne Morrison wrote that the family “trusted a man without a conscience, and my son paid the price.” Caitlin Morrison declared, “I have no sympathy for Kenny Iwamasa,” while questioning whether the lethal dose was accidental. Madeline Morrison described Iwamasa’s funeral speech as “a cruel joke” and said the revelations forced the family to “grieve…all over again.”
Prosecutors’ Allegations of Evidence Tampering
The indictment alleges that Iwamasa directed a third party (“B.M.”) to discard ketamine vials and syringes, shredded a prescription document identifying Dr. Plasencia, and deleted digital records after the death. Prosecutors also contend that Iwamasa initially provided an incomplete medication list to police, omitting ketamine and the injections he administered.
Defense Argument: Power-Dynamic Vulnerability
Iwamasa’s attorneys argue that he operated within an “unhealthy power dynamic” that left him “unable to simply say no,” suggesting that his actions were compelled by the employer-employee relationship rather than independent criminal intent.
Conflicting Reports & Gaps
Prosecutors portray Iwamasa as an active conspirator who concealed evidence, whereas the defense emphasizes coercion and lack of medical authority. The record does not disclose whether any independent medical expert corroborated the dosage levels that proved fatal, leaving the precise lethal threshold unresolved.
