While the police continue to sort out the links between the remains found on Gilgo Beach, the Post reports that the NYPD is treating two of their own as possible suspects in the strangling deaths of four prostitutes. One resigned in the 90s after an investigation found that he "spent time pursuing hookers" and paid "down-and-out-women for sex while he was supposed to be on patrol," while the other continues police work, but was stripped of his badge and gun and relegated to desk duty after "he allegedly assaulted a prostitute and got arrested during a sting operation."

The Suffolk County Police Department and the NYPD concluded that "the killer likely worked in law enforcement or was familiar with police techniques," given the nature of how and where the bodies were disposed. Though authorities believe that the killer found his victims through Craigslist ads, they have little else in the way of leads other than the phone calls he made to taunt one of his victim's sister. Previously the Suffolk County DA stated that the prevailing theory was that the deaths of the four women were most likely not related to the other bodies found on Gilgo Beach.
