Heuermann Pleads Guilty, Says He Killed Eight Women in Long Island 'Gilgo Beach' Case

In a Suffolk County courtroom, Rex A. Heuermann acknowledged he killed eight women whose remains were found across Long Island over nearly three decades — a development that brought one of New York’s most notorious cold cases closer to a legal conclusion.

Heuermann, 62, an architect from Massapequa Park, pleaded guilty to seven counts of murder and told the judge he was also responsible for the death of an eighth woman. Prosecutors said he is expected to receive multiple life sentences without the possibility of parole when he is sentenced on June 17.

The plea spares families a trial that had been scheduled for September 2026 and ends years of public uncertainty over who preyed on women whose remains turned up along Ocean Parkway and other remote stretches of Suffolk County beginning in the 1990s.

The victims Heuermann admitted killing include Melissa Barthelemy, Maureen Brainard-Barnes, Amber Lynn Costello, Megan Waterman, Valerie Mack, Jessica Taylor and Sandra Costilla. He also acknowledged causing the death of Karen Vergata; that case was not included in the charges to which he pleaded guilty.

Court and media accounts said Heuermann admitted strangling the women, sometimes dismembering them and, in several cases, wrapping remains in burlap before discarding them along Ocean Parkway near Gilgo Beach. Other victims, including Costilla and Vergata, were found miles away.

Charges and evidence

Prosecutors had charged Heuermann with three counts of first-degree murder and four counts of intentional murder tied to victims whose remains were recovered between roughly 1993 and 2010. Under New York law, a first-degree murder conviction can carry life without parole when certain aggravating factors apply, including multiple victims.

Investigators say their case relied in part on DNA and advanced forensic techniques. According to court filings and media reports, surveillance of Heuermann included collecting a discarded pizza crust, which yielded DNA that prosecutors compared with genetic material recovered from some victims. Prosecutors later sought to introduce whole-genome sequencing and forensic genealogy to strengthen links between Heuermann and the scenes where remains were found.

Defense attorneys challenged those methods, and in 2025 a New York judge ruled that key advanced DNA evidence could be admitted at trial. Legal analysts said that decision could set a precedent for how state courts handle cutting-edge forensic techniques in long-unsolved cases with degraded samples.

Investigation history

Partial remains connected to the broader investigation were found at different times and locations along Long Island’s South Shore. Costilla’s remains were found in 1993 in North Sea; a 1996 discovery on Fire Island was later identified as Vergata; Taylor’s remains were located in 2003. By 2010 and 2011, searches along Ocean Parkway near Gilgo Beach produced multiple sets of human remains, including those of Barthelemy, Brainard-Barnes, Costello and Waterman. The cluster of discoveries drew national attention and led to the "Gilgo Beach" label.

Authorities have cautioned that not every set of remains found along the South Shore necessarily points to the same offender. Separate investigations have continued into other unidentified victims and into the 2010 disappearance and death of Shannan Gilbert; Heuermann has not been charged in those matters.

Case developments and reaction

Heuermann was arrested in July 2023 outside his Manhattan office and initially pleaded not guilty. Over the following year, prosecutors expanded the indictments and prepared for a joint trial on seven killings before the guilty plea shifted the case’s trajectory.

Outside court, relatives described a complicated relief. "This has been a long journey of hope — hope that one day we would stand here and say her name with justice beside it," said Melissa Cann, sister of Maureen Brainard-Barnes, at a news conference after the hearing.

Michael Brown, Heuermann’s defense attorney, told reporters his client pleaded guilty to spare families and witnesses a prolonged, graphic trial and that the plea includes cooperation with FBI behavioral analysts. "I think that this today have hopefully some peace and some closure to the family members," Brown said.

Ongoing questions

Legal and civil questions remain. Benjamin Torres, the son of victim Valerie Mack, recently filed a wrongful-death lawsuit naming Heuermann and members of his family as defendants; attorneys for Heuermann’s relatives have denied any involvement. The civil case is expected to proceed separately from the criminal matter.

Law enforcement officials also stressed that the guilty plea does not close every unsolved death tied to remains found along the South Shore in the 1990s and 2000s. Some unidentified victims discovered during the Gilgo-era investigations have since been linked to other suspects; others remain open.

Still, for the families of the eight women Heuermann acknowledged killing, Wednesday’s hearing marked a turning point. After decades in which some victims were known more by police case numbers than by their names, families are preparing to see the man who admitted taking their loved ones' lives receive a sentence designed to ensure he never leaves prison.

When Heuermann returns to court on June 17, prosecutors will ask the court to impose multiple life terms without parole. The hearing will not answer every question about how the Gilgo investigation unfolded or why it took years to identify a suspect, but the admissions under oath bring a measure of finality to a case that has shadowed Long Island for more than 30 years and underline how both investigative setbacks and evolving forensic science shaped the search for a serial killer.
