(NEW YORK) -- The serial killer who dumped his victim's bodies in the thick brush along several miles of New York's beachfront may have dismembered several of them, law enforcement authorities have told ABC News.
The grisly twist was the latest revelation as police continued to uncover a murderous path carved along Long Island beaches by at least one killer.
Investigators have determined that bones found Monday were human, bringing the body count to nine and possibly 10 victims. It's still not clear whether a skull found alone Monday was part of victim number nine or would be victim number 10.
The bodies were discovered along a 3.5-mile stretch of beach with five of the bodies spaced out about 500 feet apart, police said.
The possibility that some of the skeletal remains were dismembered came as police were considering clear-cutting the thick brush that has made seaching the area difficult. Police fear that when the brush starts blooming in the coming weeks the search would become even more difficult. Police divers are also preparing to dive in order to search bay waters for more bodies.
Searchers have used cadaver dogs, horses and fire truck aerial ladders to scour the thick beachfront vegetation for victims. Faced with slashing rains and swampy ground, a helicopter was used for Tuesday's dragnet.
While at least several of the victims appear to have been killed and dumped by a serial killer, authorities had not yet ruled out the possibility that more than one killer was responsible for the human remains, which included those of a child.
