Matthew Perry’s Ketamine Doctor Plans Guilty Plea: Report

Plasencia and Sangha have pleaded not guilty.

Chavez’ lawyer, Matthew Binninger, told reporters outside the courthouse on Friday: “Mark is doing everything he can to try to accept responsibility for what happened in this offense. He is cooperating to the full extent possible to try to and right what wrong happened here.”

Also charged in the case are Sangha’s middle-man, Erik Fleming, and Perry’s live-in personal assistant, Kenneth Iwamasa, who administered the fatal dose to the sitcom star. Both have entered guilty pleas.

A Hollywood insider who wished to remain anonymous previously told RadarOnline.com Chavez’ plea deal had “stars and power-players absolutely s—-ing themselves” because “he could spill names of other users, dealers and contacts who have kept LA awash with ketamine and other deadly tranquilizers for years.”
