Matthew Perry's Mom Reveals the Betrayal Behind Her Son's Death

Suzanne Morrison’s letter ahead of Kenneth Iwamasa’s sentencing cuts to the heart of a tragedy that extends far beyond addiction—it’s about trust shattered at the moment it mattered most.

The Friends star’s mother trusted Kenneth Iwamasa with her son’s life. They’d known him for 25 years. When Matthew Perry was fighting his battle against addiction, Kenneth’s job was singular and sacred: be his companion, his guardian, his safety net. One phone call away from reinforcements if the pressure became too much. Instead, according to Suzanne’s powerful victim impact statement, Kenneth arranged drug supplies, injected Matthew with Ketamine—a drug he wasn’t qualified to administer—and did it again and again until her son was dead.

What makes Suzanne’s account particularly devastating isn’t just the accusation itself. It’s what happened next. After killing Matthew, she writes, Kenneth kept watching her. He sent her songs. He drew maps to help her navigate the cemetery. He insisted on speaking at the funeral, clinging to her as if he were a grieving friend rather than the man who’d betrayed everything he’d promised to protect. The cruelty of performing grief for the person you’ve harmed cuts deeper than the initial act of betrayal.

Matthew spent more than half his life fighting addiction—losing battles, getting back up, fighting again. That resilience made him human. But it also made him vulnerable to someone he’d learned to rely on, someone whose job was to say no when Matthew couldn’t. Kenneth Iwamasa knew exactly what his role was. He chose a different path, and Suzanne Perry will spend the rest of her life living with that choice.

There’s no redemption arc here, no silver lining. Just a mother’s grief and the unbearable weight of knowing her son’s death was preventable.
