The final sentencing in connection with the ketamine overdose death of “Friends” star Matthew Perry<\/a> took place Wednesday when the actor’s former live-in personal assistant was sentenced in Los Angeles to prison as part of a plea agreement. <\/p>\n

Kenneth Iwamasa, 60, of the Toluca Lake neighborhood in Los Angeles’ San Fernando Valley, was sentenced in downtown Los Angeles to three years and five months in federal prison for injecting Perry with multiple doses of ketamine before his death. He also faces 2 years of supervised released and was ordered to pay a $10,000 fine to the U.S. government. <\/p>\n

Iwamasa was the central figure in the 2 1\/2-year investigation. He was the last of five defendants to face prison time<\/a> in the October 2023 death of the 54-year-old Perry at his Pacific Palisades residence.<\/p>\n

Iwamasa bought the ketamine that caused Perry’s death and injected him with the fatal dose.<\/p>\n

The judge had strong words before the sentencing.<\/p>\n

“You were privy to Mr. Perry’s addiction (yet) continued to obtain the drug and inject him,” U.S. District Judge Sherilyn Peace Garnett said. “Your conduct was reckless.”<\/p>\n

Lisa Ferguson, Perry’s former longtime business manager and current executor of his estate, told the court that Iwamasa was the actor’s personal assistant for one year and had attempted to make himself “indispensable.”<\/p>\n

“You didn’t care,” Ferguson said. “You were now indispensable. You were Matthew’s drug supplier\u2026 You are the monster that killed him\u2026 You preyed on a vulnerable, kind, sensitive man.”<\/p>\n

NBC Dateline correspondent Keith Morrison, Perry’s step-father, spoke after the court proceeding.<\/p>\n

“He should have, he promised to, he could have called us when there was any problem,” Morrison said. “The job would’ve been safe. The money would’ve been safe. Instead, he controlled him by the use of ketamine.<\/p>\n

“His mother is truly broken. That makes me very, very sad.”<\/p>\n

Iwamasa pleaded guilty in August 2024 to one count of conspiracy to distribute ketamine resulting in death, becoming the first defendant to reach a plea deal with prosecutors. He was a key witness for the prosecution in the cases against the other defendants.<\/p>\n

Prosecutors asked the judge for a prison term of three years and five months, which was significantly less than the maximum sentence of 15 years in prison.<\/p>\n

Iwamasa was ordered to surrender by noon on July 17 to start his prison sentence.<\/p>\n
