Two men and a woman were pronounced dead at Huntington Hospital last night after they were found unconscious on a houseboat in Huntington Harbor, Suffolk Police said.
Det. Sgt. Thomas Groneman, of the Suffolk police homicide squad, said the victims were apparently overcome by noxious fumes.
"We suspect carbon monoxide poisoning," Groneman said after coming back from a preliminary investigation of the houseboat. "There was a gasoline generator on the boat."
The identities of the victims were not available, Gronemen said.
Police received a 911 call at about 8:53 p.m. from someone who rode out to the houseboat on a dinghy to check on the condition of the three people, Groneman said.
Friends of the victims had earlier asked that the person check on the three after they had not been heard from for some time following an evening on the houseboat, police said.
The houseboat was about 40 yards offshore in the harbor near the intersection of West Shore Road and Margo Lane in an area popular with clam and pleasure boaters amid dozens of moored vessels.
The first Suffolk police officers on the scene used a rowboat to get out to the vessel and upon seeing the three unconscious people immediately started performing CPR, Groneman said. Other emergency units quickly arrived by water and land and the victims were transported to Huntington Hospital, where they were pronounced dead at 9:30 p.m., Groneman said.
The white, 38-foot houseboat was expected to be taken to the Suffolk Police Marine Bureau headquarters for a forensic examination, Groneman said.
