Prosecutors have already implicated Jasveen Sangha, known as the "Ketamine Queen," who sold the drug involved in Matthew Perry's death.

She is also connected to other customer deaths, and prosecutors believe there are likely more victims given the volume of drugs Sangha sold. Sangha remains in custody without bond in connection with Perry's death. Drug dealer Eric Fleming, who reportedly served as a program director at the Bel-Air rehab Red Door, also had a resident die of an overdose while under his watch.

Additionally, Brooke Mueller’s close connections to suspects Fleming and Sangha have emerged. Mueller spent time with Sangha during one of her rehab stints, and Fleming is reportedly a godfather to one of Mueller’s children.

Mueller is said to have pressured her then-boyfriend William Cooney to join Fleming’s rehab program, where Cooney overdosed and died. Mueller may have introduced Fleming and Sangha to Perry as a means to facilitate his addiction. Federal prosecutors report that Mueller is cooperating with the investigation and is not facing any charges.

Court documents reveal the close ties between Sangha, Fleming, and assistant Kenneth Iwamasa. Iwamasa told Fleming he "cleaned up the scene" by disposing of ketamine vials and syringes and "deleted everything."

Fleming then informed Sangha that he believed they were protected since he never dealt with Perry directly, only through Iwamasa, who would be considered Perry's "enabler." In their communications, Sangha and Fleming refer to Perry using the code name "Chandler."

The doctor directly implicated in Matthew Perry’s ketamine overdose, Dr. Salvador Plasencia, continues to practice at his Calabasas urgent care clinic. The clinic remains open but must post details of Plasencia’s felony case at the front door.

While Plasencia still holds an active medical license, he has surrendered his DEA registration number and is not permitted to prescribe controlled substances. Dr. Mark Chavez faces similar restrictions.
