Who is Gilgo Beach serial killer suspect Rex Heuermann?

The Long Island man busted for the notorious Gilgo Beach murders is a self-proclaimed “troubleshooting” architect whose favorite tool for persuasion is a hammer.

Married dad of two, Rex Heuermann, 59, was busted by a special task force focusing on the murders, numerous sources told The Post on Frida𒉰y as cops swarmed his home in Massapequa Park.

He had been on the radar of the special Gilgo Beach Homicide Investigation Task Force for at least a year — and was arrested at his office at 385 Fifth Ave in Manhattan after being linked by DNA, one source said.

One neighbor, Barry Auslander, 72, told The Pos𝓀t Friday that Heuermann looked like an “average guy who had a family and went to work.”

“He grꦿew up here. I never thought he was anything but a businessman,” he said.

“I’m a troubleshooter born and raised on Long Island,” the portly, dark-haired architect  of his work mostly helping companies deal with New ﷺYork City’s Department of Buildings.

He also claimed to be an avid furniture maker inspired by✅ his dad, whom he described as a cabinet maker and an “aerospace engineer who built satellites.”

“I have one tool that’s pretty much used in every job — a cabinet maker’s hammer,” he said of both his furniture-making and consulting.

“It is persuasive enough when I need to persuade something, and it always yields excellent results.”

Asked if he meant he was “that kind of hammer for your business,” Heuermann grinned as he replied: “Sometimes I have to be the heavy framing hammer. Other times I’m the lightweight hammer just to nudge things along.”

Who is Gilgo Beach serial killer suspect Rex Heuermann?

A suspected serial killer haꦫs been arrested over the notorious Gilgo Beach murders in Long Island, The Post can confirm.

His arrest is tied to the “Gilgo Four,” four women — Melissa Barthelemy, 24, Megan Waterman, 22, Amber Lynn Costello, 27, and Maureen Brainard-Barnes, 25 — found wrapped in burlap within days of each other in 2010. 

The body of Ba🃏rthelemy was first found along Ocean Parkway on Dec. 11, 2010, sparking fears ꦕof a serial killer in the area.



By spring 2011, the ♚number of bodies had climbed to 10, including eight women as well as an unidentified man and toddler.

Heuermann’s arrest comes after Suffolk County’s new police commissioner created a special Gilgo Beach Homicide Investigation Task Force in February 2022.

Heuermann stressed that he did not work directly for the city’s Department of Buildings but acted as a “facilitator” — especially out-of-town companies that are “a little afraid of the city,” he said, chuckling throughout the interview.

“They’re overwhelmed by the city,” he said — while also mocking city workers for not being able to “understand their own codes, their own laws.”

“Part of my job became, educate the city. That’s something we’ve done ever since,” he said, adding that his main skill was “patience.”

According to his website, Heuermann has also “provided services to other city agencies, not-for-profit agencies, builders, developers and individual owners of buildings.”

Heuermann spoke of his work as a “troubleshooter” working with firms dealing with NYC’s Buildings Department in a YouTube video last year.
