LONG ISLAND, Maine — The body of a 59-year-old man found Wednesday morning in his driveway on Long Island will undergo an autopsy by the state medical examiner Thursday morning.

Maine State Police on Wednesday identified the man as Steven Michael Hanson of Island Avenue, a lobsterman whose body was discovered by two men who were walking on the island, according to Stephen McCausland, spokesman for the Maine Department of Public Safety.

McCausland confirmed Thursday that state police have not classified the death as “suspicious,” but as “unexplained.”

The Cumberland County Sheriff’s Office, which provides public safety services for the island of about 200 year-round residents located about six miles from Portland in Casco Bay, received a call from the men at about 6:30 a.m. Wednesday, Lt. Tom Williams said. Based on information provided by the men, the sheriff’s office immediately sent a team of patrol deputies and detectives to the scene.

“The information was that we had a deceased male by the side of the road, and the witness observations were that there was a lot of blood evidence,” Williams said Thursday.

That information prompted the sheriff’s office to call in the Maine State Police, which sent a half-dozen detectives to the island. The detectives, led by Lt. Brian McDonough, spent most of Wednesday at Hanson’s Island Avenue home and talking to family members, McCausland said.

“We reached out, trying to retrace his footsteps within the last 24 hours,” McCausland said. “That was done through a series of interviews.”

McCausland declined to release additional information until after an autopsy, scheduled to take place at the state medical examiner’s office at about 11 a.m. Thursday.
