A 34-year-old Saco man was sentenced to more than five years in prison for bilking an elderly York woman out of more than $90,000 for unneeded or substandard home improvement jobs and yard work, police said.

Billy Jack Adams was arrested Feb. 7 after police, working with the victim’s family and a local bank, determined much of the work done at the woman’s house was unnecessary or substandard, Sgt. Thomas Cryan said in a press release. Adams also was convicted of forging a check that had been made payable to someone else so that he could get the money.

Adams also is being investigated for similar behavior in Haverhill, Mass., Cryan said.

Adams was sentenced Thursday, Aug. 9, to six years on the felony theft charge and five years on the forgery charge, both sentences running concurrently, Cryan said.
