A 61-year-old man was found floating dead in the water Sunday near his houseboat in the Fort Washington area of Prince George’s County, authorities said.

Investigators have not found any indications of foul play, though they are awaiting results of an autopsy to determine how George A. Goins died, said Sgt. Art Windemuth, a spokesman for the Maryland Natural Resources Police.

Friends found Goins’s body Sunday afternoon, Windemuth said, and a Prince George’s County fire boat recovered it just after 3 p.m.

Goins lived alone in a houseboat on Swan Creek near the Tantallon Marina, according to Windemuth. He said friends last saw Goins Friday evening. Those friends could not reach him Saturday, and they decided to stop by his boat to check on him Sunday, Windemuth said.

Goins was floating face down in the water when he was found, Windemuth said.
