Authorities are investigating the death of a 74-year-old man whose body was recovered near Bremen hours after he was reported missing from his sailboat Sunday, according to the Maine Marine Patrol.

Friends of Mark Metzger, of Waltham, Massachusetts, reported him missing around 11:40 a.m. Sunday, the agency said in a statement Monday morning. Metzger was not aboard his 19-foot sailboat, which had been anchored on the western side of Bremen Long Island.

Members of the public located Metzger’s body around 1:30 p.m. near Long Island Ledges, the Marine Patrol said.

The Coast Guard transported Metzger’s body to shore. A local funeral home was expected to transfer the body to the Office of Chief Medical Examiner in Augusta for an autopsy, the Marine Patrol said.

Along with the Marine Patrol, the Lincoln County Sheriff’s Office, the Coast Guard, the Maine Forest Service and local emergency responders assisted in the search.
