Seventy-seven-year old Carl Neimes had not been seen since he left to go fishing on the St. Marks River last Wednesday. That afternoon his boat was found running circles on the river.
Helicopters and boats were used in the search.
The Florida Fish and Wildlife Conservation Commission says the body of Neimes was located after it surfaced just before two o'clock Tuesday afternoon not far from where his empty boat was found.
An autopsy is scheduled for Wednesday.
