WANTAGH, N.Y. — State police found no trace of bodies today during a search along a Long Island access road near the oceanfront site where 10 sets of human remains were found earlier.

The search is to continue Tuesday along another access road, police said.

Officers are looking for remains or other clues in what could be a case of a serial killer. The investigation began as a search for a missing New Jersey prostitute last seen in the area a year ago.

About 50 officers, plus six cadaver dogs and two helicopters, searched the dense underbrush along the Wantagh State Parkway for six hours today.

State police Capt. James Dewar said there was no specific information, evidence or tip that prompted the wider search. He said the Wantagh was targeted because it leads to Ocean Parkway. Ten sets of human remains have been found in the thick brush along Ocean Parkway since December, including those of Megan Waterman, 22, of Scarborough, Maine.

While the missing prostitute has not been found, four other bodies have been identified. The missing woman’s family and friends marked the one-year anniversary of her disappearance on Sunday.

Dewar noted that the two parkways are “similar in terrain and in isolation.”

That means dense underbrush, few homes and difficult going, the captain said.

The highway and its bikes-and-pedestrians path were closed from about 9 a.m. to about 3 p.m.

Police said the Robert Moses Causeway, a few miles to the east, would be closed for a time on Tuesday while officers search alongside it.

The state police were joined by officers from Nassau County and the state Department of Environmental Conservation, Dewar said.
