Assistant Sentenced for Injecting Matthew Perry with Ketamine

The assistant also falsely claimed Perry was responsible for hiding the bottles of ketamine in the home, prosecutors said in the legal filing.

He informed that he 'cleaned up the scene' of the actor's home after he died, according to prosecutors.

Prosecutors said Iwamasa told Fleming that he destroyed physical evidence, changed Perry's digital passwords and 'deleted everything' from computers as he sought to cover up evidence of the star's ketamine use.

Perry’s sisters Caitlin and Madeline Morrison were critical of Iwamasa in statements submit to U.S. District Judge Sherilyn Garnett in a May 20 court filing reviewed by People.

'It is difficult to put into words the sense of betrayal I felt when I found out what Kenny had done,' Madeline Morrison said. 'In many ways, it felt like my brother died all over again. 

'Everything I believed about the day he died - everything Kenny told us - was a lie.'

She said that 'the idea that someone my brother considered family could betray him in such an unimaginable way is something I never could have conceived.'

Madeline said that Iwamasa's behavior was suspicious in the wake of her brother's passing.

'A few days after Matthew died, my sister and I went to choose clothes for him to be buried in - one of the most surreal and heartbreaking experiences of my life,' Madeline said. 'I remember how manic and unsettled Kenny seemed.

'He repeatedly volunteered his version of events without being asked, as if he were being interviewed rather than mourning a friend.'

She added, 'In reality he was trying to distract us from the truth: that he had injected my brother with a lethal dose of ketamine and left him in a hot tub to die.'

The sentencing comes two weeks after Perry's drug counselor Erik Fleming was ordered to serve two years.

An emotional Fleming said: 'It’s truly a nightmare I can’t wake up from. I’m haunted by the mistakes I made.'

A judge ordered Fleming, who has been free on bond for about two years, to turn himself in to serve his term in 45 days. He was also sentenced to three years of probation.

This came a month after Perry's 'Ketamine Queen' drug dealer Jasveen Sangha was handed down , along with three years of supervised release.

Sangha pled guilty to five federal charges related to Perry's death and has been in federal custody since her arrest in August 2024.

Fleming connected Perry to Sangha and ultimately gave her up to investigators.

The prosecutors wrote in a filing that 'Sangha’s actions show a cold callousness and disregard for life. She chose profits over people, and her actions have caused immense pain to the victims’ families and loved ones.' 

In the same month that Perry passed away, Sangha and Fleming sold 51 vials of ketamine to the actor, which were then handed over to Kenneth Iwamasa, Perry's personal assistant, prosecutors said.

Perry battled addiction for many years, a struggle that intensified during his time on Friends, when he became one of the biggest stars of his generation as Chandler Bing.

His rise to fame alongside Jennifer Aniston, Courteney Cox, Lisa Kudrow, Matt LeBlanc, and David Schwimmer on the iconic Friends sitcom from 1994 to 2004 was overshadowed by personal struggles. 

Perry openly admitted that his addiction issues frequently interfered with his work during those years.
