BUCKSPORT, Maine — Officers were still working Monday afternoon to try to determine what caused a motorcycle accident that killed a local man Sunday evening, according to the police chief.

The man who died in the accident is Nathaniel Coleman, 41, of Bucksport, police Chief Sean Geaghan said Monday.

Coleman was not wearing a helmet when his motorcycle went off Millvale Road around 6:30 p.m. Sunday, according to Geaghan. He declined to comment on what kind of injuries Coleman suffered in the accident or on possible factors that may have caused the motorcycle to go off the road.

“The investigation is ongoing at this point,” Geaghan said.

The police chief said Coleman was driving a 1998 Harley-Davidson north on Millvale Road when the accident occurred at the intersection with Jacob Buck Pond Road. Millvale Road curves slightly to the left, he said, and Coleman’s motorcycle went off the road to the right, going into a ditch and then across a driveway.

Geaghan said no other vehicles were involved in the accident. He said police do not believe Coleman or his motorcycle struck any objects such as a parked vehicle or a tree when he went off the road.
