SKOWHEGAN, Maine — A Norridgewock man was indicted Friday by a Somerset County grand jury in connection with the shooting death of an Anson man nearly two years ago.

Robert Nelson, 40, was charged with murder, Maine Department of Public Safety spokesman Stephen McCausland said in a news release issued Friday night.

Nelson was being held at Somerset County Jail in Skowhegan on an unrelated matter when the indictment was returned. Maine State Police detectives went to the jail Friday afternoon to formally charge Nelson, who likely will appear in Somerset Superior Court on the murder charge next week.

The murder charge stems from the shooting death of Everett Cameron, 60, of Anson on Oct. 31, 2009, McCausland said.

The shooting occurred while Cameron was sitting alone in his pickup truck on a woods road off Town Farm Home, a short distance from his home, according to previous reports published in the Bangor Daily News.

Town Farm Road is located just off Route 234 in Anson, a community of about 2,600 located near Skowhegan in southern Somerset County.

Cameron spent the first part of Oct. 31 hunting. He returned home in the early afternoon and changed out of his hunting clothes, investigators said shortly after the shooting.

At some point, he drove his 1990 silver-and-maroon Chevrolet pickup truck to a woods road adjacent to his home and parked about 20 feet from the road. Cameron’s girlfriend found his body about 4 p.m. that day.

It was not clear Friday what prompted the shooting.

McCausland said that Nelson was a resident of North Anson when the shooting occurred but that detectives who have been investigating the case say Nelson and Cameron did not know each other.
