Kenneth Iwamasa, who served as Matthew Perry's personal assistant, is facing sentencing for his involvement in the actor's overdose death on October 28, 2023. Iwamasa, who earned $150,000 a year, was responsible for administering ketamine to Perry, which ultimately led to his death. Court filings reveal that Iwamasa injected Perry with multiple doses of the drug in the days leading up to his death, and on the day of the incident, Perry reportedly requested a large dose. Iwamasa has pleaded guilty to conspiracy to distribute ketamine resulting in death, and prosecutors are seeking a sentence of three years and five months, which is less than the 15-year term given to a drug dealer involved in the case. Perry's family has expressed deep anger and betrayal, with his mother stating that they had trusted Iwamasa to be a guardian in Perry's battle against addiction. The family described how Iwamasa's actions tainted their memories of Perry's funeral, as he addressed mourners despite being responsible for their loved one's death. The LA County Medical Examiner confirmed that ketamine was the primary cause of death, with drowning as a contributing factor.
