(CBS/WCBS/AP) OAK BEACH, N.Y. - Investigators expanded their search Tuesday of a remote, densely overgrown stretch of a Long Island barrier island as they searched for more victims of a possible serial killer.
It was also determined Tuesday that the three most recent sets of remains, which were found on April 4, were not those of New Jersey woman Shannan Gilbert, whose disappearance sparked the search that has led to the discovery of eight bodies, reports CBS station WCBS.
Authorities will continue their search of the area on Wednesday.
The recently discovered remains are in addition to the remains of a victim found last week in the area, 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.
Gilbert, like the other women whose remains have been identified, advertised as a prostitute on Craigslist. She went missing in May.
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.
