WARREN — A Maine man convicted of killing an 18-year-old woman more than 40 years ago has lost a bid for parole.

Michael Boucher is one of only four prisoners in Maine who are eligible for parole, which was eliminated in Maine in 1979.

His bid for parole was rejected after a hearing Thursday at the Maine State Prison. He’ll be eligible to go before the board again in five years.

Boucher was convicted of murder in 1991 of the slaying of Debra Dill back in 1973, before parole was banished. The 63-year-old Boucher was tied to the slaying in 1991 and police found that he had a box of Dill’s belongings. Investigators say he chose her at random, strangling her and beating her with a hammer in Litchfield.
