ALFRED — A Saco man will serve 19 years in prison for attempted murder and arson related to domestic violence crimes in Saco and Dayton on Oct. 16, 2012.

Donald A. Henson, 48, entered Alford pleas at York County Superior Court Friday. An Alford plea is part of a plea bargain in which the defendant does not admit guilt but acknowledges there is evidence to convict them, were the case to go to trial, according to statement from York County District Attorney Kathryn Slattery.

Police said Henson set fire to his house at 2 Maple St. in Saco on Oct. 16 and then left. The fire burst a pipe, which extinguished the fire before any damage could take place.

Henson then went to Goodwin Mills Road in Dayton, where his estranged wife Kimberly Henson was staying, in a home owned by his mother-in-law, Barbara Curran.

Police were called to the scene after gunshots were fired. After a more than three-hour police standoff, during which the house burned, Henson surrendered to police after taking refuge in a barn.

Henson’s wife and those at the house with her were able to leave safely.

Henson was sentenced to 20 years for the attempted murder, with all but 14 years suspended. Henson will serve a five-year sentence for arson consecutively with the murder sentence, according to Slattery.Henson is to serve eight years on probation, during which he is prohibited from contacting the victims and is not allowed to possess firearms. He must engage in psychological and substance abuse counseling.

Henson had said through his attorney, around the time of the incident, that he had worked as a civilian contractor in Iraq and had post-traumatic stress disorder.
