Los Angeles — Kenneth Iwamasa, the longtime personal assistant to actor Matthew Perry, is scheduled to be sentenced Wednesday in federal court after pleading guilty in August 2024 to one count of conspiracy to distribute ketamine resulting in death. Authorities say the charges stem from Perry’s Oct. 28, 2023 death and a 2½-year nationwide probe into ketamine distribution. This sentencing concludes the multi-defendant federal case as prosecutors seek a sentence of three years and five months for Iwamasa, who cooperated and became the prosecution’s key witness; defense filings described him as an employee with particular vulnerability in his relationship to Perry. Judge Sherilyn Peace Garnett, who previously sentenced four co-defendants, will issue the final determination Wednesday.
