Woman reveals disturbing encounter with Gilgo suspect Rex Heuermann

A young Long Island woman revealed Friday that she had a disturbing encounter recently with Gilgo Beach murder suspect Rex Heuermann earlier this month in a park — and that she was so shaken that she filed a police report.

Ally, 25, who declined to provide her last name, said she was shocked to see the man nabbed in the killings was the same creep who she encountered on July 3 in Brady Park, which is just a few minutes’ drive from Heuermann’s home on 1st Avenue in Massapequa Park.

“I was going for a bike ride over in Brady Park and he came up behind me and he asked me what time it was,” Ally exclusively told The Post.

“He was trying to compliment me. Asking me if I came here often. Asking me my name,” Ally told The Post of the 59-year-old architect’s bizarre behavior.

“He had very dirty clothes on. He popped right out of the woods. Everywhere I went in the woods he would pop out somewhere,” she continued.

She said he kept pestering her, approaching her twice during her trip to the park.

“The first time he came up behind me I felt like breathing behind me. Then he ask me what time it was and he saw the picture of me and my boyfriend on my phone. So he was just asking me questions,” she said.

Eventually, Ally said, she was so upset by Heuermann’s conduct that she called her sister to pick her up.

“That’s when I got (my sister) on the phone because I got nervous. She had to pick me up. I couldn’t even go home from my bike ride,” she recalled.

Ally filed a police report about the encounter.

Two weeks later, she was horrified when she heard that Heuermann had been arrested in connection with the deaths of at least three women whose remains were discovered on Ocean Parkway near Gilgo State Park in December 2010.

“My mom showed me the picture and I started screaming. I got so nervous because I realized that that was him,” Ally told The Post.

Who is Gilgo Beach serial killer suspect Rex Heuermann?

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

Rex Heuermann, 59, a married dad of two and architect at a New York City firm, has a home on 1st Avenue in Massapequa Park, sources told The Post.

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 Barthelemy was first found along Ocean Parkway on Dec. 11, 2010, sparking fears of 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, a married dad of two, pleaded not guilty on Friday to a slew of charges – including three counts of first-degree murder – related to the deaths of Melissa Barthelemy, Megan Waterman, and Amber Costello, who bodies were all found dumped along Ocean Parkway near Gilgo State Park in December 2010.

He was linked to the infamous crimes in part through DNA obtained from a discarded pizza crust, his bail application revealed.

Heuermann is also the prime suspect in the death of Maureen Brainard-Barnes, who was the first of the so-called “Gilgo Four” to disappear, the document stated.

Ally is not the only person who thought Heuermann was sinister: one former professional acquaintance described the father of two as “weird.”

“He was always odd. He’d mosey around. We knew something was odd about him,” the individual, who asked not to be named, told The Post Friday.

“I feel like it makes sense he’s a serial killer. He’s a weirdo,” they added.
