Previous version:

A man was found dead in the water Thursday about 100 yards north of where he and another man were thrown from a boat a few hours earlier, said St. Johns County Fire Rescue spokesman Lt. Bob Snell.

Neither man's identity was released Thursday night.

The men were thrown overboard as their boat made a sharp turn in the water near the Conch House around 7 p.m. Thursday, Snell said.

The first man was able to swim to Conch Island and was not injured, Snell said.

St. Johns County Marine Rescue crews and the St. Johns County Sheriff's Office searched for the other man from the Conch House area to the inlet for hours.

A Sheriff's Office helicopter searched the waters for the man when marine rescue crews had to stop looking because of darkness.

Around 10:15 p.m., they found his body about 100 yards north of the Conch House.

More details about the incident were not available Thursday night.
