GILGO BEACH - A week after the first body was found on Gilgo Beach, followed by the discovery of three more bodies, police are trying to determine the victims' identities and find the person who dumped their remains.At first, police believed the female bodies could have been those of two missing Craigslist escorts, 22-year-old Megan Waterman, of Maine, and 23-year-old Shannan Gilbert, of New Jersey. However, over the past week, forensic testing established that the two women were not among the victims. Yesterday, police and cadaver dogs again scoured a 10-mile stretch of Ocean Parkway, but after failing to find any additional human remains, they wrapped up their search.Detectives are now looking at thousands of missing persons' cases and waiting for the results of DNA tests on the four bodies.Investigators say it could take weeks to identify the victims and determine the causes of death. Detectives are asking anyone with information to call Crime Stoppers at 1-800-220-TIPS.
