LOS ANGELES - A San Diego doctor charged as part of the investigation of the overdose death of Matthew Perry is expected to plead guilty in a federal court in Los Angeles.
Dr. Mark Chavez is set to appear in front of a judge on Wednesday.
He has agreed to plead guilty to one count of conspiracy to distribute ketamine.
The "Friends" star died last year of an overdose of the powerful surgical anesthetic.
Chavez and two others have pleaded guilty in the case and agreed to cooperate with prosecutors as they go after bigger targets, including the doctor Chavez admitted to working with to sell the drug to Perry.
