Rex Heuermann, a 59-year-old architect, has been charged with first- and second-degree murder for the deaths of three women in the Gilgo Beach serial killings. He is also the prime suspect in a fourth murder. The charges come after a 12-year investigation into the Long Island Serial Killer (LISK) case.
Former NYPD homicide detective Kevin Gannon explained that DNA evidence was crucial in linking Heuermann to the victims. Investigators obtained DNA from a pizza crust discarded by Heuermann, which matched genetic material found on the remains of the victims. This breakthrough allowed authorities to connect the suspect to the crimes.
The victims, known as the 'Gilgo Four,' were Melissa Barthelemy, Megan Waterman, Amber Costello, and Maureen Brainard-Barnes. All were young sex workers who had been strangled to death. Their bodies were discovered in 2010 along Ocean Parkway near Gilgo Beach on Long Island.
Gannon noted that identifying the victims through DNA was a key step in building a timeline and spotting patterns. The victims were often enlisted via Craigslist, leading to the killer being dubbed the 'Craigslist Killer.' The FBI's Violent Criminal Apprehension Program (ViCAP) helped law enforcement share data and link the cases.
Heuermann pleaded not guilty to all charges during a preliminary hearing at the Arthur M. Cromarty Criminal Court Complex in Riverhead, New York. The investigation continues as authorities seek to determine if he is connected to other unsolved murders in the area.
