Suffolk homicide detectives say a body was found off of Fire Island.

They say partial remains of a man were pulled from the water after being stuck by a boat's propeller last week.

Detectives believe the man was already dead before being struck.

They say more remains were discovered Sunday afternoon in the same area.

Officials believe they are from the same unidentified man.

Anyone with any information is asked to call Crime Stoppers at 1-800-220-TIPS.
