Long Island serial killer? Medical Examiner to study unidentified beach-area remains

(CBS/WCBS/AP) NEW YORK - The Nassau County Medical Examiner is expected to begin forensic analysis Tuesday on the additional sets of human remains found east of Jones Beach State Park to determine if they're connected to four other victims whose bodies police say could be linked to a Long Island serial killer.

State police said they completed their search of the extended area, aside from helicopter searches which will continue, reports CBS station WCBS.

On Monday, Nassau County police found a ninth, and possible tenth set of human remains, which could possibly provide still more evidence of a serial killer using South Shore beaches as a dumping ground, reports the station.

The first set of bodies found were four women discovered by police back in December. All were identified as prostitutes who advertised on Craigslist, leading authorities to believe they could possibly be dealing with a serial killer.

More recently, four more remains were found that have yet to be identified.

Then days ago, in addition to the eight sets of remains already found, a skull was discovered near a bird sanctuary in Nassau County, as well as another set of human remains near a landmark water tower, reports the station.

"I think this is an area that the killer feels very safe in and there's no reason to believe that it's not the same killer. There are some subtle differences. The first four were covered in burlap, the last four were not, but that doesn't mean they're different people," said Lawrence Kobilinsky of John Jay College of Criminal Justice, reports the station.

Police in December were following up on the disappearance of a Jersey City woman, Shannon Gilbert, who was seen working as a Craigslist escort in Long Island area. Her disappearance remains an open case.
