CINCINNATI: Another Ohio doctor charged with illegal drug distribution plans to plead guilty in his case.

A federal indictment against Joon Chong alleges he was one of six doctors at a southern Ohio clinic who wrote illegal painkiller prescriptions.

The April indictment alleged that customers would travel hundreds of miles weekly to visit the clinic and pay $200 per visit for painkillers.

A document filed in federal court Monday says Chong will plead guilty to illegally acquiring and distributing prescription painkillers.

The filing says Chong, who faces four years in prison and a $250,000 fine, agrees to cooperate with investigators in exchange for the deal.

The indictment says clinic prescriptions contributed to the deaths of at least two patients.

Another clinic doctor has indicated he’ll also plead guilty.
