The heavily thicketed ground that borders a highway along a stretch of New York beaches where as many as 10 bodies have been found is now being examined as the disposal site for a serial killer and a possible dumping ground for other killers.
More bones were found today along the Long Island beaches and have been sent to the medical examiner's office to determine whether they are from one or two people. One of the remains is just a skull.
Authorities involved in the painstaking probe along the popular stretch of public beach now involves more than 125 state, federal investigators and local investigators from two neighboring counties.
Investigators have said they believe that a serial killer was responsible for the murders, and Nassau County Executive Edward Mangano said today that police are looking for "the animal that has obviously taken the lives of a number of people."
But probers now says that they cannot rule out the likelihood that more than one killer will be linked to the bodies which total seven sets of adult human remains, a toddler's remains and the bones found today that may be from one or two people.
"Now the question is connectivity," one law enforcement supervisor told ABC News. "Geographically it is secluded and makes a perfect dumping ground."
According to authorities, any differences in the method of murder, disposal, burial, and any DNA evidence will be among the elements of a rigorous forensic examination. The probe will include the assistance of state police and FBI agents including evidence collection experts, behavior science investigators and profiling gurus.
According to ABC News sources the first bodies discovered, now badly decomposed, were wrapped in burlap and were prostitutes who advertised on Craigslist.
In addition to those grisly skeletal remains found buried in the thick ground cover beside the ocean, authorities continue to search for Shannan Gilbert, a 24 year old sex worker who also advertised on Craigslist and was last seen near the beach area shouting, "He is trying to kill me."
The second set of remains, discovered over the past two weeks, were not wrapped in burlap and one was a toddler. Authorities have not said whether the toddler's remains were linked to one of the adult remains, or is unrelated.
According to multiple sources familiar with the investigation a number of persons are under investigation in connection with the first eight corpses, and those include persons of interest with a law enforcement or emergency service background, and familiarity with the beach. All of those who were described to ABC News were local suspects. They were under examination for any role in the killing of some or all of the victims
The corpses were strewn along a several-mile stretch that includes state run and county beaches. The stretch begins about 45 minutes from Manhattan and includes the popular Jones Beach State Park.
"In some respects, the location and the usage of the internet to contact some of the victims offered the same features for the killer or killers: seclusion and anonymity," said Michael Balboni, former deputy Secretary for Public Safety for the state of New York.
One of the bodies found so far is that of prostitute Melissa Barthelemy. Barthelemy's teenage sister told "Good Morning America" today that she has received taunting phone calls from a man who is believed to have killed her sister.
