As early as August, Mark Chavez, 54, signed an agreement with prosecutors in Los Angeles. Along with two other people, he acknowledged several minor charges in exchange for cooperating in the investigation of those considered more responsible for the fatal overdose of the "Friends" star last year – another doctor and a reseller, known as the "ketamine queen" of Los Angeles.
The other two who are cooperating with the federal prosecutor are Perry's assistant, who acknowledged helping him obtain and inject ketamine, and an acquaintance of Perry who acknowledged acting as a drug supplier and middleman.
Chavez's lawyer, Matthew Binninger, said after Chavez's first court appearance on August 30 that he is "extremely remorseful and trying to do everything in his power to make amends for the mistakes that were made".
The "Friends" star was found dead in his pool in Los Angeles last October. During the autopsy, the doctors found traces of the drug ketamine in his blood.
The suspects are said to have discussed Perry's death shortly after it occurred and together tried to destroy evidence and conceal their involvement in the events.
