Matthew Perry’s assistant Kenneth Iwamasa has been sentenced to over three years in prison for his role in the actor's fatal 2023 ketamine overdose.

Kenneth Iwamasa, the live-in personal assistant to actor Matthew Perry, was sentenced to three years and five months in federal prison on Wednesday for his role in the actor's death [2]. Iwamasa, who pleaded guilty to conspiracy to distribute ketamine resulting in death, was the final individual sentenced among five people charged in the investigation [2].

**Key takeaways**
* Kenneth Iwamasa was sentenced to 41 months in prison for his role in providing the ketamine that caused Matthew Perry's death [2].
* Judge Sherilyn Peace Garnett ruled that Iwamasa acted with recklessness, noting he had the choice to refuse the fatal injections [2].
* Perry’s family, including his stepfather Keith Morrison, expressed that they trusted Iwamasa as a family member before his actions led to the actor's death [2].
* The investigation into Perry’s death involved multiple parties, including medical professionals and a street dealer known as the "Ketamine Queen" [2].

## The legal proceedings and sentencing
During the sentencing hearing in Los Angeles, Judge Sherilyn Peace Garnett addressed the power dynamic between the 60-year-old assistant and the late *Friends* star [2]. While Iwamasa’s defense attorney argued that his client was merely accommodating Perry’s wishes and lacked the power to refuse, the judge rejected this, stating that Iwamasa was "unwilling" rather than unable to stop the drug administration [2]. Iwamasa, who was paid $150,000 annually, admitted to acting as the actor's enabler and de facto doctor, ultimately performing the injections that led to Perry's death on October 28, 2023 [2].

The sentencing concluded a legal process that began after investigators served a search warrant at Perry’s home in January 2024 [2]. Iwamasa initially lied to police and disposed of evidence, but later cooperated with prosecutors and became a key informant [2]. During the hearing, Perry’s business manager, Lisa Ferguson, accused Iwamasa of isolating the actor from other medical and sober-living support to maintain his own influence [2]. Iwamasa expressed regret for his actions, offering condolences to the family in court [2]. In addition to the prison term, he was ordered to pay a $10,000 fine and will serve two years of probation [2].

## Why it matters
The sentencing marks the end of a high-profile criminal investigation into the death of one of television's most recognizable stars [2]. The case highlighted the dangers of ketamine addiction and the legal consequences for those who facilitate the substance use of others, even when acting as employees or friends [2]. While the legal saga has concluded, Perry’s family noted that the sentencing does not mitigate the loss of the actor, who starred in the hit sitcom *Friends* from 1994 to 2004 [2]. The court’s decision to impose the sentence sought by prosecutors underscores the judicial system's focus on individual accountability in cases involving fatal drug distribution [2].
