This is some scary stuff considering there is a killer on the loose in my backyard. (not Literally)
OAK BEACH, N.Y. - The search for missing New Jersey woman Shannan Gilbert continues Tuesday along a remote Long Island beach after investigators discovered three additional sets of human remains Monday, bringing the total number of bodies found in the area to eight.

The new remains are in addition to the remains of a victim found in the area last week, about 45 miles east of New York City. That victim has not been identified, and police have not positively connected those remains to the bodies of four prostitutes found nearby in December.

Police discovered the bodies while searching for 24-year-old Shannan Gilbert, who went missing in May in the area, and are investigating whether any of the newly-discovered remains are hers.

"The medical examiner is going to be looking at the possibility that Shannan Gilbert is one of the remains," Suffolk County Police Commissioner Richard Dormer said. "We do have forensic and information available to the ME that would either prove it's her or eliminate her."

The search for Gilbert is expected to resume Tuesday. Gilbert, like the other women whose remains have been identified, reportedly advertised as a prostitute on Craigslist.

Authorities have identified the four bodies found in December as Amber Lynn Costello, 27, originally of Wilmington, N.C.; Megan Waterman, 22, of Scarborough, Maine; Maureen Brainard-Barnes, 28, of Norwich, Conn.; and Melissa Barthelemy, 24, of Buffalo, N.Y.

Police suspect a serial killer but so far have no suspects.

According to CBS affiliate WCBS, police searching on foot and from above in helicopters and fire truck buckets found the latest three sets of remains as they scoured tick-infested underbrush and evergreens on the barrier island south of Long Island, Dormer said.

They also used cadaver dogs, police academy cadets, detectives and volunteer firefighters.

Investigators have searched the area, roughly 7.5 miles, several times since December. Dormer said the discovery of the latest remains gives investigators new possible leads into the killings of all the victims.
