Maine State Police have charged Patrick Dapolito with murdering his wife at the couple’s Limington home on March 16, according to a police spokesman.

Detectives arrested Dapolito, 39, at the State Police Barracks in Gray at 5:30 p.m. Saturday, said Steve McCausland, spokesman for the Maine Department of Public Safety. Dapolito had arranged, through his attorney, to turn himself in, McCausland said.

Dapolito was taken to the York County Jail in Alfred and will make his first court appearance on the murder charge Monday in York County Superior Court.

Dapolito had reported Kelly Winslow-Dapolito missing from their home on Mike’s Way in Limington on March 18. Her body was found the next day off Route 26 in Upton, an isolated town of about 65 residents on the New Hampshire border where her in-laws own a house and 200 acres of land.

Dapolito’s parents live in Upton but had been in Florida, where they typically go in the winter, Town Clerk Jim Rector said.

Dapolito, 39, and Winslow-Dapolito, 30, had been married about six months. Four children lived with them.

The State Medical Examiner’s Office determined that Kelly Winslow-Dapolito died from a gunshot wound to the head and ruled the death a homicide, McCausland said.

Dapolito had been interviewed during the investigation and had been cooperative, McCausland said.

His home telephone was disconnected, and a jail guard wouldn’t make him available for comment Saturday. Police said they don’t know who his lawyer is.
