WEST ISLIP, N.Y. (CBSNewYork/AP) -- Investigators say nothing was found in their latest search for possible remains on a barrier island south of New York's Long Island.
Recent aerial photographs taken by the FBI of Captree Island prompted investigators to return there on Tuesday in their search for more bodies in a possible serial killer case.
State police say officers searched 11 specific locations for about three hours near the Robert Moses Causeway on Tuesday.

The highway is just up the road from Ocean Parkway where 10 sets of human remains have been discovered since December.
State police are not specifically saying if the photos, taken in April, yielded additional evidence.
Police believe a serial killer may be responsible for the deaths of at least four prostitutes whose bodies were found in the area. Authorities suspect other killers may have also left victims along the remote parkway, going back at least a decade.

The investigation began as a hunt for missing New Jersey prostitute Shannan Gilbert, who was last seen in the area of Oak Beach a year ago. She has not been found, but the discoveries of other remains have raised fears of a serial killer. Four young women have been identified among the dead.
Residents near Gilgo Beach, where the search originated, were shocked by the recent gruesome discoveries.
"To find all these bodies here, we're shocked. We're a close community, leave our doors unlocked," one neighbor said.
None of the four most recently recovered bodies have been identified.
"We have no information on the sex, or age or any other information on the four remains we found," said Richard Dormer, Suffolk Police Commissioner.
