Matthew Perry's assistant, who injected fatal ketamine dose, sentenced to 41 months 

Perry’s personal assistant since 1992 and his live-in aid since 2022, Iwamasa is the fourth individual charged and sentenced in connection with Perry’s death, including “Ketamine Queen” Jasveen Sangha, who received 15 years in prison. 

“Kenny knew, should he feel unduly pressured, that with one phone call to any number of the people in Matthew’s orbit, reinforcements would be on the way, and his job would be safe,” wrote Suzanne Morrison, Perry’s mother, in a letter to the court, per The Hollywood Reporter. “But instead of protecting Matthew, he aided and abetted illegal drug taking, arranged for one source of supply, then another. Shot the drugs into Matthew’s body though he was not in the least qualified.”
