According to Newsday, investigators are facing a huge hurdle in their effort to identify the victims.
Law enforcement and forensic experts say that because the remains were dumped on the beach, they were more exposed to elements that degrade DNA.
Those elements include salty air, ultraviolet light, heat and humidity.
Five victims have been identified, and there are at least four others waiting to be ID'd.
On Monday, Spota announced that the human remains discovered along Ocean Parkway beaches are from eight victims, which are being divided into separate cases.
The four women from the original case have been identified as prostitutes murdered by a serial killer. Maureen Brainard-Barnes, who was last seen on July 9, 2007, was murdered first. Melissa Barthelemy was next, having disappeared almost exactly two years later in 2009. Megan Waterman vanished on June 6 of last year, and Amber Lynn Costello disappeared in early September of 2010.
The dismembered remains of two more women have been found since police began scouring the brambles along Gilgo Beach in April.
Police say these two murders are connected to each other, but not linked to the first four.
The next victim is an unidentified baby girl, between 1 and 2 years old. Investigators say there are no signs of trauma, but homicide has not been ruled out.
"What is now very clear is that the area in and around Gilgo Beach has been used to discard human remains for some period of time," Spota said.
The chilling new details have people in the beachfront community on edge.
"Maybe it is somebody who could live in this area," one resident said. "You really have to be a little more careful."
