Maine police are investigating the circumstances surrounding the death of a man whose body was found on a bridge in Lisbon.

Authorities say the man's body was found on the Lisbon-Durham bridge Saturday morning.

Lisbon Police Sgt. Ryan McGee tells the Sun Journal that he doesn't believe the cause of death is suspicious, but said he could not release details until the Medical Examiner's Office completes an autopsy.

He would not say who found the body or how it was discovered. (AP)
