A body was pulled from the St. Clair River Sunday morning north of Fawn Island.
The Lambton OPP Crime Unit, Forensic Identification Service, and detachment officers responded at 8:30 a.m.
Police said a body had been found by a fisherman and brought ashore at Port Lambton. They said an autopsy has been conducted and the death has been deemed non-suspicious at this time.
The identity of the deceased is still pending but investigators have reason to believe the individual is a resident of the United States.
