UPDATE: This early release from the OPP mistakenly identified the location that the body was recovered from as in Lake Nipissing, not the Sturgeon River.

Tragedy on local waterways this long weekend.

Police say a body recovered from Lake Nipissing Monday afternoon has been examined under the direction of the Office of the Chief Coroner and Forensic Pathology Service to determine if they are the remains of a 57-year-old man who fell into the Sturgeon River, Sunday afternoon.

Police say a local man was observed sitting on a chair on a wooden raft when the chair broke and he fell into the river.

Sunday at approximately 3:10pm, members of the Ontario Provincial Police North Bay Detachment Marine Unit, Underwater Search and Recovery Unit, Unmanned Aerial System and Aviation Services, as well as the West Nipissing Police Service, West Nipissing Fire Service and Emergency Medical Services, responded to the possible drowning on the Sturgeon River in West Nipissing. The emergency teams were unable to locate the man despite an exhaustive search.

The OPP says pending notification of the next of kin, the name of the deceased is not being released at this time.
