A doctor charged with giving Matthew Perry ketamine in the month leading up to the “Friends” star's overdose death will plead guilty, according to an agreement filed in court Monday. Dr. Salvador Plasencia agreed to plead guilty to four counts of distribution of ketamine, according to the signed document filed in federal court in Los Angeles. In exchange for his plea, prosecutors agreed to drop three additional counts of distribution of ketamine and two counts of falsifying records. Federal prosecutors said in a statement that the plea carries a maximum sentence of 40 years in prison. They said Plasencia is expected to formally plead guilty in the coming weeks.
