"To let all know ... the remains found have been confirmed to be my daughter, Megan Waterman ... a very sad day," wrote Waterman's mother, Lorraine Ela, on a Facebook page devoted to her missing daughter.
The victim had been missing since June 6, 2010 and was last seen at a Hauppauge Holiday Inn Express near exit 56 of the Long Island Expressway.
Waterman, of Scarborough, Maine, had been working as an escort on Craigslist, but was reportedly with her boyfriend that night at the hotel.
Police discovered her body 15 miles from the hotel along a deserted stretch of highway running along the beach last month.
All four bodies were reportedly found clustered, each within five hundred feet of the nearest other victim. The bodies were likely dumped from a vehicle as long as two years ago based on the state of decomposition.
Police acknowledge the cluster of bodies does not appear to be a coincidence but at a news conference today they backed away from earlier suggestions that they were the victims of a serial killer.
Dormer also announced that they are very close to determining the identities of the three other bodies that were found in subsequent searches.
The New York City medical examiners are busy analyzing DNA provided by families who contacted them after the bodies were discovered, and determining whether or not it matches that of the bodies.
Detectives now think that the victims were not killed where they were found, and that the killer only used the stretch of marshy grassland as a dumping ground.
