Long Island Architect Rex Heuermann Pleads Guilty to Killing 8 Women

Shackled at the wrists and dressed in a dark suit, Rex Heuermann stood in Suffolk County Court in Riverhead and admitted to killing eight women. The 62-year-old former Manhattan architect, lifelong Massapequa Park resident, and suspected Gilgo Beach serial killer pleaded guilty on April 8, 2026, closing the door on what had been one of American true crime's most agonizing cold cases.

Under direct questioning by Suffolk County DA Ray Tierney, Heuermann confirmed he strangled all eight victims, used burner phones to contact them, wrapped their bodies in burlap before dumping them, and dismembered some. When Tierney asked, "You killed each victim in the same manner, namely strangulation?" Heuermann answered, "Yes."

The eight women Heuermann admitted to killing are Melissa Barthelemy, Megan Waterman, Amber Costello, Maureen Brainard-Barnes, Sandra Costilla, Valerie Mack, Jessica Taylor, and Karen Vergata. Vergata, 34, represents the most significant expansion of the case: she was a previously uncharged murder, and under the terms of the plea deal, Heuermann will face no separate prosecution for her death. Remains of six of the eight women were found in scrub along Ocean Parkway near Gilgo Beach; partial remains of Jessica Taylor were first recovered in Manorville, miles away.

The case broke open in December 2010, when police searching for missing 23-year-old Shannan Gilbert found four sets of remains within a quarter mile of each other near Gilgo Beach. Those victims, known to true crime followers as the "Gilgo Four," had all worked as escorts advertising on Craigslist and were last seen between July 2007 and September 2010. In total, ten sets of human remains were eventually recovered along the isolated beach highway.

Heuermann was not identified until DA Tierney reopened the cold cases in 2022. Investigators zeroed in on his Chevrolet Avalanche through an old witness tip, then ran surveillance until he discarded pizza crusts into a Manhattan garbage can. DNA extracted from those crusts matched a male hair recovered from the burlap used to restrain one of his victims. He was arrested on July 13, 2023, in Midtown Manhattan. Detectives spent more than 12 days searching his Massapequa Park home, located across a bay from where many of the victims were dumped.

What made the case especially disturbing to investigators was the evidence of deliberate methodology. Heuermann operated under the alias "Thomas Hawk" to contact dozens of sex workers and maintained what authorities described as a written "blueprint" of his killings, complete with supply lists, dump site locations, and personal notes including reminders to "burn gloves" and to "consider a hit to the neck next time." In September 2025, Judge Timothy Mazzei ruled that both the DNA evidence and the planning document were admissible, effectively neutralizing months of suppression arguments from the defense.

As part of the plea agreement, Heuermann will serve three consecutive life sentences followed by four consecutive sentences of 25 years-to-life. He will also cooperate fully with the FBI's Behavioral Analysis Unit. That cooperation clause matters beyond this case: other unidentified remains along Ocean Parkway remain unsolved, including those of a female toddler and several unidentified adults.

Defense attorney Michael Brown said the decision was ultimately Heuermann's own. "There came a point in this defense where Rex said, I want to plead guilty," Brown told reporters, adding that his client wanted to spare victims' families, and his own, from a trial. Brown indicated Heuermann would speak at sentencing, scheduled for June 17, 2026.

The son of victim Valerie Mack, who was six years old when his mother vanished, filed a civil lawsuit against Heuermann's family in the days before the plea. Asa Ellerup, Heuermann's ex-wife who filed for divorce following his 2023 arrest and was present in the courtroom, issued a statement expressing her prayers for the victims and their families. Attorney Gloria Allred represents most of the victims' families.

Eight names now have answers. The Jane Does of Ocean Parkway still do not.
