A Long Island architect who spent nearly two decades leading a double life as a predator pleaded guilty Wednesday to the murder of seven women and admitted to the killing of an eighth, bringing a devastating conclusion to the mystery of the Gilgo Beach killings.
Rex Heuermann, 62, appeared before a packed courtroom in Riverhead, New York, where he entered pleas to three counts of first-degree murder and four counts of intentional murder. The proceedings were marked by profound emotion, with victims’ relatives weeping as the details of the crimes were read into the record. Heuermann will be sentenced to life in prison without the possibility of parole at a later date.
While not formally charged in her death, Heuermann also admitted during the hearing that he killed Karen Vergata in 1996. The admissions provide a sense of finality to a case that for years bedeviled law enforcement, agonized families, and captured the attention of a global audience obsessed with true crime.
Authorities stated that Heuermann strangled his victims—many of whom were sex workers—over a 17-year period. He buried their remains in remote locations, most notably along a desolate stretch of highway across the bay from his own home.
A courtroom of grief and silence
The atmosphere inside the Suffolk County Court was heavy, with approximately half the seating reserved for law enforcement and the families of the deceased. Heuermann, dressed in a white button-down shirt and black blazer, remained stoic throughout the hearing. He provided brief, clipped answers to prosecutor Ray Tierney and kept his gaze fixed forward, never looking toward the gallery of grieving relatives.

Outside the courtroom, the scrutiny extended to Heuermann’s own family. Reporters and camera crews swarmed his ex-wife, Asa Ellerup, and their daughter as they entered the building.
“It’s a difficult day,” said Robert Macedonio, an attorney representing Ellerup. “No one can envision ever in their life standing here in a courthouse on a line surrounded by media having their ex-husband accused of seven, potentially eight homicides. It’s unimaginable. There’s no way to prepare for it.”
The victims of the South Shore
The horror of the case began to unfold in 2010 when police, while searching for a missing person, discovered multiple sets of human remains along the scrub of Ocean Parkway. Over the following years, forensic analysis and DNA testing helped investigators identify the women and connect them to other remains found across Long Island.
The victims included Melissa Barthelemy, Maureen Brainard-Barnes, Amber Lynn Costello, Valerie Mack, Jessica Taylor, and Megan Waterman, whose remains were all recovered near Gilgo Beach. Sandra Costilla was found more than 60 miles away in the Hamptons, while Karen Vergata’s remains were found on Fire Island in 1996 and again near Gilgo Beach in 2011.
| Victim | Primary Recovery Location |
|---|---|
| M. Barthelemy, M. Brainard-Barnes, A. Costello, V. Mack, J. Taylor, M. Waterman | Ocean Parkway / Gilgo Beach |
| Sandra Costilla | The Hamptons |
| Karen Vergata | Fire Island / Gilgo Beach |
The forensic breakthrough
Despite the immense public interest and the creation of a specialized task force, the case remained cold for over a decade. The tide turned in 2022 when a new police commissioner revamped the Gilgo Beach investigation. Detectives used a vehicle registration database to link Heuermann to a pickup truck seen by a witness during the 2010 disappearance of one of the victims.
Heuermann had lived for decades in Massapequa Park, a short drive from the burial sites. Once identified as a suspect, a grand jury authorized more than 300 subpoenas. Investigators discovered that Heuermann had used burner phones to contact victims and had an internet search history filled with violent torture pornography and a preoccupation with the remarkably investigation that was hunting him.
The definitive evidence came from a daring surveillance operation in Manhattan. Detectives tailed Heuermann and recovered a discarded pizza box from a sidewalk trash can. DNA extracted from the partially eaten crust matched a male hair found on burlap used to bind one of the victims. Heuermann was arrested in July 2023.
A subsequent search of his home revealed a basement vault containing 279 weapons. On his computer, police found what they described as a “blueprint” for his crimes—meticulous checklists designed to minimize noise, clean bodies, and destroy forensic evidence.
Next steps in the legal process
With the guilty pleas entered, the legal focus shifts to the formal sentencing. While the sentence of life without parole is expected, the court will hold a final hearing to finalize the terms and allow further victim impact statements.
Suffolk County District Attorney Ray Tierney is expected to provide further details regarding the closure of the case during a scheduled news conference. This resolution marks the conclude of one of the most protracted and haunting serial murder investigations in New York State history.
