Matthew Perry’s Assistant Sentenced for Role in Actor’s Ketamine-Related Death

Matthew Perry’s former live-in assistant, Kenneth Iwamasa, has been sentenced to 41 months in prison for his role in the actor’s 2023 death, which was linked to a ketamine overdose. The sentencing, delivered by Judge Sherilyn Peace Garnett in Los Angeles, marks the conclusion of a legal process that unfolded over nearly two years following Perry’s passing.

The Legal Proceedings

Iwamasa, 60, pleaded guilty in August 2024 to one count of conspiracy to distribute ketamine causing death. Prosecutors alleged that he administered the drug to Perry, who was found dead in his backyard hot tub in October 2023. According to court documents, Iwamasa collaborated with two doctors to provide Perry with over $50,000 worth of ketamine in the weeks preceding his death. Despite lacking medical training, Iwamasa was described as a key figure in Perry’s care during his struggles with addiction.

The judge emphasized Iwamasa’s awareness of Perry’s addiction and his efforts to conceal evidence after the actor’s death. Iwamasa was also ordered to pay a $10,000 fine and serve two years of supervised release following his prison term. He is scheduled to report to prison on July 17, 2026.

A Moment of Apology

During the sentencing hearing, Iwamasa took the stand and expressed deep remorse to Perry’s family. “I’m so sorry to all of you. I’m just so sorry to have done illegal acts that I will forever regret,” he said, adding, “I hope I’ll be a cautionary tale to someone who’s in my position to make better choices.” His statement was met with silence from the courtroom, reflecting the gravity of the situation.

The prosecution had initially sought a sentence of three years and five months, but the court imposed a harsher penalty, citing the severity of the offense and the trust Iwamasa breached as Perry’s caretaker.

The Broader Context

Perry’s death sparked widespread discussions about ketamine use and the challenges of addiction treatment. The case also highlighted the dangers of unregulated drug distribution, particularly when individuals without medical expertise administer powerful substances. A separate article from the *Winnipeg Free Press* detailed the final days of Perry’s life, including his reported requests for “substantial doses” of ketamine, though these accounts were not independently verified.

Two other individuals, including the doctors who supplied the ketamine, are also facing charges in the case. The legal proceedings underscore the complex web of responsibility surrounding Perry’s death, with Iwamasa being the first of five defendants to reach a plea agreement.

Impact on Perry’s Family

Perry’s mother and stepfather were present during the sentencing, according to *People.com*. The actor’s passing left a profound impact on his loved ones, who have since spoken publicly about their grief. While the legal system has rendered its verdict, the emotional toll of the tragedy remains a focal point for those close to Perry.

The case has also prompted calls for greater oversight of ketamine use, particularly in private settings. Health advocates have urged caution, noting that while ketamine is approved for medical use, its recreational or unregulated administration poses significant risks.

Looking Ahead

As Iwamasa prepares to begin his prison term, the case serves as a stark reminder of the consequences of drug-related misconduct. For Perry’s family and fans, the sentencing brings a measure of closure, though the loss of the actor—known for his iconic role as Chandler Bing on *Friends*—continues to resonate. The legal outcome also raises broader questions about addiction support, medical accountability, and the need for systemic reforms to prevent similar tragedies in the future.
