SEBAGO — A man was shot and killed Saturday outside his home in Sebago, and another man – an acquaintance of the victim – was arrested and charged with murder a short time later, Maine State Police said.

The shooting took place about noon at 331 Hancock Pond Road, said Stephen McCausland, spokesman for the Maine Department of Public Service.

The victim was identified as Charlie Cross, 66.

The alleged assailant, David Pinkham of Bridgton, was taken into custody when Bridgton police stopped him in his vehicle after he had left the scene, said state police Sgt. Chris Harriman.

Harriman said Pinkham, 67, was taken to the Cumberland County Jail in Portland.

The shooting was reported by Cross’ girlfriend, Paula Simonds, 59, who lived with him in the house, McCausland said. The two men knew each other, McCausland said, but police do not yet have a motive for the shooting.

Harriman said Pinkham was known to Bridgton police but that police had not had any dealings with Cross. Neither Pinkham nor Cross has a criminal record in Maine, according to state criminal history records.

Authorities cordoned off the scene around the white clapboard house, which had several trucks, cars and a plow in its driveway.

Neighbors Mike and Erica Ford said they didn’t know the names of the couple who lived in the house but knew them enough to wave to.

The Fords said nothing ever happens in their neighborhood, which is surrounded by a 400-acre preserve.

“We probably see one police car a year,” said Mike Ford.

McCausland said state police detectives are being assisted by Cumberland County sheriff’s deputies and the Maine Attorney General’s Office.
