Physician Salvador Plasencia, who was charged in the death of Matthew Perry, pleaded guilty to distributing ketamine to the "Friends" actor.

Charging longtime addict Perry premium prices for the ketamine, L.A.-based Plasencia and Dr. Mark Chavez of San Diego clearly felt they had lucked into a gold mine with the actor and his desire for the drug. “I wonder how much this moron will pay,” Plasencia ruthlessly texted Chavez at one point during their dealings with Perry.

A doctor charged with giving Matthew Perry ketamine in the month leading up to the “Friends” star’s overdose death has agreed to plead guilty.
