Kenneth Iwamasa, the personal assistant to late actor Matthew Perry, was sentenced Wednesday to three years and five months in federal prison for his role in administering the fatal ketamine overdose that led to Perry’s death in October 2023. The sentencing took place in a Los Angeles federal court before Judge Sherilyn Peace Garnett, who also imposed two years of probation and a $10,000 fine.

Iwamasa, 60, is the final individual to be sentenced in the case surrounding Perry’s overdose at age 54. He pleaded guilty in August 2024 to one count of conspiracy to distribute ketamine resulting in death and cooperated with investigators throughout the proceedings. He is scheduled to begin serving his prison term on July 17.

During the hearing, Iwamasa expressed remorse, apologizing to Perry’s family and stating he would carry the weight of his actions for the rest of his life. The sentencing drew emotional victim impact statements from members of Perry’s family, including his stepfather, television correspondent Keith Morrison, and his estate manager. Morrison criticized Iwamasa for continuing to inject the actor despite the clear dangers, saying, “You were part of the family. You could have called someone. You kept injecting him.” He also accused Iwamasa of living indulgently while Perry suffered.

Perry’s mother, Suzanne Perry, who was present at the sentencing, submitted a heartfelt statement recounting her trust in Iwamasa as her son’s companion and guardian during his struggle with addiction. She described the immediate aftermath of Perry’s death, recalling the heartbreaking scene of finding her son’s body in their backyard and her anguish at the morgue. “Matthew trusted Kenny. We trusted Kenny,” she said in her statement, condemning Iwamasa as a man “without a conscience” whose actions cost her son his life.

Other individuals connected to the case have also faced consequences. Erik Fleming, a former Hollywood producer who introduced Perry to one of the key figures in the case, pleaded guilty and received a two-year sentence earlier this month. Jasveen Sangha, known as the “Ketamine Queen,” was sentenced last month to 15 years in prison after accepting responsibility for her involvement. During her sentencing, Morrison expressed mixed emotions, emphasizing Perry’s talent and lamenting the loss of what should have been a longer career.

Additional convictions include Mark Chavez, who was sentenced in December to eight months of home confinement after admitting to providing Perry with ketamine despite awareness of his addiction, and Dr. Salvador Plasencia, who received a two-and-a-half-year sentence the same month. Prosecutors noted Plasencia had administered ketamine to Perry on at least one occasion in a public location, an act reportedly criticized by Chavez.

Together, the proceedings mark a conclusion to a complex and tragic case that highlighted the dangers of illicit drug distribution and the vulnerabilities faced by those battling addiction.
