Prominent among the names is 41-year-old Jasveen Sangha, a dual U.S.-British citizen who in Hollywood circles has been dubbed “the queen of ketamine. ” According to the prosecution, she provided Perry’s fatal dose. She has pleaded not guilty; if found guilty at trial, she could be sentenced to life in prison.

A doctor pleaded guilty to giving Matthew Perry ketamine in the month leading up to the “Friends” star’s overdose death.

Iwamasa, who admitted in court documents to administering the ketamine on the day that Perry died, pleaded guilty in August 2024 to one count of conspiracy to distribute ketamine causing death, the DOJ said. He is scheduled to be sentenced in November.
