CNN —Mark Chavez, one of the two doctors charged in connection with “Friends” star Matthew Perry’s death, has pleaded guilty to one count of conspiracy to distribute ketamine as part of a plea agreement during a court appearance in Los Angeles on Wednesday. Chavez is accused of providing Dr. Salvador Plasencia – who is also charged in connection with Perry’s death and has previously pleaded not guilty – with the ketamine given to Perry through a fraudulent prescription, according to court documents. Plasencia and Chavez are among the five people who have been charged in connection with the death of the beloved actor. Perry’s personal assistant Kenneth Iwamasa and an acquaintance of Perry’s, Erik Fleming, were also charged and, along with Chavez, have been cooperative with prosecutors. Fleming, who pleaded guilty to one count of conspiracy to distribute ketamine and one count of distribution of ketamine resulting in death, and Iwamasa, who pleaded guilty to one count of conspiracy to distribute ketamine causing death, have sentencing dates set in the coming months.
