A Saco man has been sentenced to six years in jail for bilking an elderly York woman out of $90,000 by charging her for unneeded or substandard home improvement jobs and yard work. Authorities say 34-year-old Billy Jack Adams was convicted and sentenced Aug. 9 in York County Superior Court on theft and forgery charges. He was sentenced to six years on the theft charge and five years on the forgery charge to be served concurrently. Adams was arrested Feb. 7. Police also learned from a local bank that Adams had forged his name on a check made out by the woman to another party. Detectives say they found the forged check in Adams’ possession. Adams faces similar charges in Haverhill, Mass.
