A Fairfield Police officer now says he will plead guilty to stealing painkillers from a local veterinarian. According to online court records, Ryan Mills told the Washington County Court Monday (5/20) he will change his plea to guilty.  Mills was arrested on New Year’s Day after he was seen leaving the Veterinary Clinic in Fairfield.  Mills later admitted to investigators that he had entered the clinic several times to take painkillers.  There’s no word if Mills is pleading guilty to a lesser charge; he will be sentenced June 21.
