BOW, N.H. — A hunter came upon what appeared to be human remains in dense brush beneath power lines off South Bow Road in Bow early Saturday, prompting a death investigation by local and state authorities, NBC Boston and the Concord Monitor reported. Both outlets said investigators do not yet know who the person was, how old they were or their gender.

The hunter dialed 911 at about 7:30 a.m., both outlets reported, and the Monitor said the call went to Bow police. Local officers and state troopers then went to the site and confirmed a person had died there. The Monitor cited the state attorney general's office for the account of the discovery.

New Hampshire State Police and the attorney general's office are assisting Bow police, NBC Boston reported. A Monitor photo caption said the state police Major Crime Unit responded to the scene.

Bow Police Chief Ken Miller said there was no known threat to the public, according to the Monitor. The paper reported that officers remained on site as of 2 p.m., photographing and documenting the area. Kip McDaniel, who chairs the Bow Select Board, declined to comment to the Monitor.

The Office of the Chief Medical Examiner planned an autopsy the day after the discovery, both outlets reported; NBC Boston said it would be done at the office in Concord. Authorities described the case as being at an early stage and said they did not expect to release more until the autopsy is complete, according to NBC Boston.

Investigators want to hear from people who walked near the power lines stretching from South Bow Road to Twist Hill Road in Dunbarton during the week before the remains were found, NBC Boston reported. Tips can be phoned to 603-628-8477, both outlets said, or emailed to [email protected], and callers may remain anonymous, according to NBC Boston.
