The body found floating in Sheepshead Bay may have been a murder victim, circumstances suggest. Authorities fished the 6-foot-2, 240-pound grey-haired white male out of the waters near Shore Boulevard and Exeter Street last Friday. Tied to his wrists and ankles were five-pound weights, but NYPD has not yet ruled the case a homicide. According to a Courier-Life report, the victim did not have any gunshot or stabbing wounds, and his identity continues to remain a mystery. An autopsy was scheduled for Monday, but results are inconclusive pending further tests.
