A man from Augusta is going to prison for three years for robbery, theft and stealing drugs, including medication from a man who was recently murdered. 23-year old Joshua Theriault-Patten pleaded guilty yesterday to three separate crimes. Among them, stealing prescription medication from 47-year-old Paul Allen in January. Allen’s body was found over the weekend in Hallowell and another man is charged with his murder. The Kennebec County District Attorney says because Allen is dead, one of the drug charges against Theriault-Patten was dropped. Theriault-Patten also admitted to beating up a man in August, stealing $300 and a cell phone.
