Mark Chavez (R), the "ketamine doctor" who is charged in connection with actor Matthew Perry's death from an accidental ketamine overdose, walks with his attorney Matthew Binninger to speak to the media as they leave the Roybal Federal Courthouse in Los Angeles after his court appearance on August 30, 2024. Five people who allegedly supplied ketamine to "Friends" star Matthew Perry in a bid to exploit his drug addiction for profit have been charged in relation to his overdose death. Perry had fallen back into addiction in the autumn of 2023, when he began to be supplied by Salvador Plasencia and Mark Chavez, both doctors.
