GILGO BEACH - Police say the search for bodies along Ocean Parkway in what seems to have been a serial killer's dumping ground will continue in Nassau County starting Monday.

Suffolk police announced today the completion of the current phase of the search.

Speaking during a news conference, Suffolk County Police Commissioner Richard Dormer added that K-9 units and detectives may return to the area during the ongoing investigation.

"We're not going to give up," he said. "We're going to be back here."

A new search is expected to begin on Nassau County's side of Ocean Parkway Monday involving ladder trucks, cadaver dogs borrowed from Suffolk police and mounted units.

Investigators have found the bodies of eight people near Gilgo Beach since December, among them Amber Costello, of North Babylon.

Cops say none of the remains that have been found are those of missing New Jersey prostitute Shannan Gilbert, who was last seen running and screaming from her client's house in Oak Beach. Police say the client, Joseph Brewer, is not a suspect.

Gus Colletti, of Oak Beach, says he is haunted by a feeling of guilt because he was likely one of the last people to see Gilbert the night she vanished when she ran to his house in a panic.

"This is a life that could've been saved if I knew what was going to happen," he says. "I would've detained her."

Colletti says he later stopped a man driving down his street in an SUV looking for Gilbert. He says after the man spotted Gilbert coming out of her hiding spot behind a boat, he took off after her.
