NEW YORK — In a chilling conclusion to a prolonged investigation, Rex Heuermann confessed on Wednesday to the murder of eight young sex workers over a 17-year span, a series of crimes that earned him the notorious label of the Gilgo Beach serial killer.

During the court proceedings, Judge Timothy Mazzei inquired, “Do you feel it’s in your best interest to plead guilty rather than go to trial?” Heuermann responded affirmatively, “Yes, your honor.”

At 62 years old, Heuermann accepted a plea deal that sentences him to three consecutive life terms, followed by four additional sentences of 25 years-to-life each, as confirmed by Suffolk County District Attorney Ray Tierney. This plea ensures he will not face further prosecution related to these eight victims, although he is required to continue assisting the FBI with their investigations.

In the courtroom, dressed in a dark suit with his hands shackled, Heuermann admitted to killing Melissa Barthelemy, Megan Waterman, and Amber Costello. Their remains were discovered along Ocean Parkway near Gilgo Beach.

District Attorney Tierney posed the question, “You killed each victim in the same manner, namely strangulation?” Heuermann replied simply, “Yes,” with a dispassionate demeanor.

Among the spectators, Heuermann’s ex-wife, Asa Ellerup, appeared visibly tense, clutching the chair in front of her. Seated beside their daughter, she was surrounded by the victims’ families and numerous investigators who have been dedicated to solving this case for many years. Additional investigators lined the courtroom, standing by the walls and windows.

Heuermann pleaded guilty to strangling to death Sandra Costilla, Valerie Mack, Jessica Taylor, Maureen Brainard-Barnes, whose remains were found near Gilgo Beach and elsewhere on Long Island.

Heuermann also admitted he intentionally causing the death of Karen Vergata, 34, who was last heard from on Valentine’s Day 1996. Her legs and feet were found later that year on Fire Island. Her skull was found in 2011 near Tobay Beach in Nassau County.

The killings went unsolved for two decades until the Suffolk County district attorney’s office, New York State Police and the FBI first identified Heuermann as a suspect in 2022 through his Chevrolet Avalanche, a distinctive pickup truck sparsely purchased on Long Island.

From there, prosecutors said they compiled DNA from a hair lifted from burlap used to wrap some of the victims and from pizza crust in the trash outside Heuermann’s Manhattan office.

Heuermann used the alias “Thomas Hawk” to communicate with dozens of sex workers and to amass an extensive collection of torture pornography. Prosecutors said he kept a “blueprint” of his killings that included a list of supplies, locations of “dump sites” and reminders to “burn gloves” and “consider a hit to the neck next time.”

He is scheduled to be sentenced on June 17.
