The Spin


Narrative A

Kenneth Iwamasa was paid $150,000 a year to keep Matthew Perry sober, and instead he injected him with lethal doses of ketamine and left him to die in a hot tub. Perry's family trusted Iwamasa for 25 years, and he exploited that trust at every turn, arranging drug supplies, hiding evidence from police and even speaking at the funeral. A 41-month sentence is nowhere near enough for that level of betrayal.

Narrative B

Matthew Perry himself demanded the ketamine, explicitly telling Iwamasa to "shoot me up with a big one" on the day he died. Perry had been actively sourcing illegal drugs through multiple dealers, dating app hookups and a whole network of suppliers, all while a nursing team was present. Iwamasa was complicit, but Perry was a grown adult who drove his own addiction with relentless determination.
