Psychologists who provided a behavioral analysis of the Gilgo Beach serial killer in 2011 came remarkably close to characterizing suspect Rex Heuermann, who was apprehended recently. Serial killer specialists informed the New York Times in 2011 that the individual responsible for the murders of at least four women and discarding their bodies along Ocean Parkway in Long Island from 2007 to 2010 was likely an educated Caucasian male residing on the South Shore of Long Island. They predicted that the suspect would hold a stable job, be financially well-off, drive a luxury vehicle, possibly be married, and appear inconspicuous to the general public.

“This is someone who can blend in effortlessly,” stated Scott Bonn, a sociology assistant professor at Drew University in Madison, NJ, and an expert on serial killers. “He must possess the charm and persuasiveness to lure these women under false pretenses. He has exhibited social adeptness. He might even come across as charming,” he elaborated, referring to the individual who killed Maureen Brainard-Barnes, Melissa Barthelemy, Megan Waterman, and Amber Costello.

These characteristics closely align with Heuermann, an architect from Massapequa Park and a married father of two who now faces charges related to the Gilgo Beach murders. Experts suggested that the unidentified subject would fall within the age range of mid-20s to mid-40s. Heuermann, aged 59, would have been around 46 at the time of the last victim’s death, Costello, in September 2010.

The positioning of the victims’ remains was another significant clue for profilers. Eleven sets of human remains were found along a 10-mile stretch of a suburban Long Island beach highway. The secluded nature of the area indicated that the perpetrator was familiar with it, as former FBI profiler Jim Clemente pointed out. “He didn’t stumble upon that location,” Clemente emphasized. Given that each victim went missing during the summer, Clemente suggested a potential seasonal pattern in the killer’s connection to the area, possibly coinciding with the absence of his family members during the summer months.

Investigators revealed that the murders occurred when Heuermann’s wife and children were away. His wife was out of state when Waterman disappeared, in New Jersey when Costello vanished, and in Iceland when Barthelemy was last seen alive, according to Heuermann’s bail application.

Heuermann entered a plea of not guilty to six charges during a court appearance in Yaphank, New York, following his arrest in Manhattan. He faces three counts of first-degree murder and three counts of second-degree murder for the deaths of Barthelemy, Waterman, and Costello, as per court documents.

Authorities searched Heuermann’s residence in Massapequa Park, located about a 25-minute drive from where the 11 sets of human remains were discovered along Ocean Parkway. His office in Manhattan was also subject to investigation.

Neighbors described Heuermann as unsettling and expressed surprise at his arrest. According to a bail application, Heuermann conducted numerous explicit online searches, including inquiries for local sex workers. Some of these searches allegedly involved child pornography.

Suffolk County District Attorney Raymond Tierney disclosed that Heuermann’s arrest followed the analysis of five significant hair samples from four victims using mitochondrial DNA technology.

The suspect reportedly utilized disposable phones, and authorities were able to trace calls made to some victims by matching cell phone ping locations. Additionally, DNA from a discarded pizza box played a role in Heuermann’s apprehension.

Police removed a black Chevrolet Avalanche truck from Heuermann’s property. Fox News’ Greg Norman, Michael Ruiz, Marta Dhanis, and Charles Creitz contributed to this report.
