Doctor who helped supply Matthew Perry ketamine pleads guilty to drug charge

LOS ANGELES — A San Diego doctor became the third person to plead guilty in the case of Matthew Perry 's fatal drug overdose, as prosecutors collect cooperators in an attempt to convict two bigger targets they say are responsible for the death of the 'Friends' star.

Dr. Mark Chavez, 54, entered the plea Wednesday to a felony count of conspiring to distribute the surgical anesthetic ketamine in federal court in Los Angeles, after reaching a plea agreement with prosecutors in July.
