The case surrounding the death of beloved "Friends" actor Matthew Perry has reached its final chapter in federal court. On Wednesday, May 28, 2026, Kenneth Iwamasa, Perry's longtime live-in personal assistant, is scheduled to be sentenced for his central role in supplying and administering the ketamine that led to the actor's fatal overdose in October 2023.
Perry, known worldwide for his portrayal of Chandler Bing, was found unresponsive in the hot tub at his Pacific Palisades home. The Los Angeles County medical examiner ruled the death an accident caused by the acute effects of ketamine, with drowning listed as a contributing factor. At age 54, Perry's passing shocked fans and highlighted the dangers of substance misuse even among those who appeared to be on a path to recovery.
Background on Matthew Perry's Struggles and Death
Matthew Perry had been open about his battles with addiction throughout his life. In his 2022 memoir "Friends, Lovers, and the Big Terrible Thing," he detailed decades of alcohol and drug use, multiple stints in rehab, and the physical toll it took on his body. Despite these challenges, Perry had achieved significant periods of sobriety in the years leading up to his death and was actively working on his mental and physical health.
The night of October 28, 2023, however, took a tragic turn. Iwamasa, who lived with Perry and earned approximately $150,000 annually as his trusted aide, had been procuring ketamine for the actor. Court documents reveal that Iwamasa injected Perry with the drug multiple times that day—reports indicate between six and eight injections in the final hours—despite having no medical training or licensing. Perry was later discovered in the jacuzzi, and efforts to revive him were unsuccessful.
Who Is Kenneth Iwamasa?
Kenneth Iwamasa, now 61, served as Perry's personal assistant for several years. Described in court filings as someone the actor and his family trusted implicitly to support his sobriety, Iwamasa instead became deeply involved in facilitating Perry's ketamine use. He acted as a go-between, purchasing the drug from suppliers and personally administering it to Perry on a near-daily basis in the period leading up to the actor's death.
Iwamasa's plea agreement outlines how he conspired with others to obtain and distribute ketamine illegally. He admitted to receiving shipments of the drug, storing it, and then injecting Perry repeatedly without proper medical oversight. This hands-on involvement set him apart from other defendants in the case and made him a key witness for prosecutors.
The Investigation and Charges
Federal authorities launched a thorough investigation following Perry's death, uncovering a network of individuals involved in the illegal distribution of ketamine. In August 2024, five people were charged in connection with the case. Iwamasa was the first to reach a plea deal, pleading guilty to one count of conspiracy to distribute ketamine resulting in death.
The charge carries a maximum penalty of 15 years in prison. Prosecutors have recommended a sentence of 41 months (three years and five months) for Iwamasa, citing his cooperation with the investigation and his role as a witness against co-defendants. The U.S. Attorney's Office for the Central District of California has emphasized the seriousness of distributing a substance that directly contributed to a high-profile death.
Other Defendants and Their Outcomes
The case involved several co-conspirators, each playing distinct roles in the supply chain:
- Jasveen Sangha, known in court documents as the "Ketamine Queen," was sentenced to 15 years in prison in April 2026. She admitted to running a large-scale drug operation and supplying the ketamine that ultimately killed Perry, as well as another individual in a prior incident.
- Erik Fleming, a North Hollywood drug dealer, pleaded guilty to related charges and faces sentencing in the coming months.
- Two physicians, Dr. Mark Chavez and Dr. Salvador Plasencia, were also charged. Chavez received a sentence of 30 months, while Plasencia's case is ongoing or resolved separately.
These outcomes reflect the wide net cast by federal prosecutors in addressing the illegal ketamine trade tied to Perry's death.

Iwamasa's Plea Deal and Cooperation
Iwamasa's decision to plead guilty early and cooperate significantly advanced the prosecution. He provided crucial testimony and evidence that helped secure charges against the suppliers and medical professionals involved. Court records note that he destroyed some evidence early in the investigation but later fully cooperated after his arrest.
His plea acknowledged the gravity of injecting Perry multiple times on the day of his death. Despite his central position, prosecutors have taken a measured approach to his sentencing recommendation, balancing accountability with his assistance to authorities.
Family Reactions and Victim Impact
Perry's family has submitted emotional impact statements ahead of the sentencing. They expressed deep betrayal, noting that they had trusted Iwamasa to help maintain Perry's sobriety rather than enable his drug use. The statements highlight the profound loss felt by loved ones and the ongoing pain caused by the circumstances of his death.
Friends and colleagues from the entertainment industry have also shared tributes, remembering Perry's talent, humor, and advocacy for addiction recovery. The case has sparked conversations about the responsibilities of those in close personal or professional relationships with individuals struggling with substance use.
Broader Implications for Drug Laws and Celebrity Cases
This high-profile prosecution underscores federal efforts to combat the illegal distribution of ketamine, a substance increasingly misused outside clinical settings. While ketamine has legitimate medical uses, including in some mental health treatments, its recreational diversion carries severe risks, as tragically demonstrated here.
The case also raises questions about accountability in personal assistance roles and the challenges of supporting someone in recovery. Legal experts note that such prosecutions aim to deter suppliers and intermediaries who profit from or facilitate dangerous drug access.
Public Response and Media Coverage
News of the upcoming sentencing has generated significant public interest, with many expressing a mix of sadness over Perry's passing and a desire for justice. Social media discussions reflect ongoing admiration for the actor alongside calls for stricter oversight of prescription and distribution practices.
Major outlets have followed the case closely, providing updates on the investigation, pleas, and sentences. The proceedings have highlighted the human cost of the opioid and substance crisis, even as it involves a drug like ketamine that is sometimes portrayed differently in popular culture.
Lessons on Ketamine Use and Addiction Support
Perry's story serves as a reminder of the complexities of addiction recovery. Ketamine, when obtained illegally and used without medical supervision, can lead to respiratory depression, loss of consciousness, and fatal outcomes—particularly when combined with other factors like immersion in water.
Experts emphasize the importance of professional treatment programs, peer support, and removing access to substances that undermine recovery efforts. The case illustrates how trusted individuals can sometimes become part of the problem rather than the solution.
Looking Ahead
As the final sentencing approaches, the focus remains on closure for Perry's family and accountability for all involved. The resolution of this case marks the end of a two-and-a-half-year federal investigation but leaves a lasting legacy through increased awareness of substance misuse risks.
Perry's openness about his own journey continues to inspire others facing similar challenges. For those seeking resources on addiction recovery or support, organizations like the Substance Abuse and Mental Health Services Administration offer guidance and helplines.
