Rex Heuermann, a 62-year-old Massapequa Park architect, pleaded guilty on April 8, 2026 to murdering seven women in the Gilgo Beach serial killings and admitted to an eighth in a packed Riverhead courtroom. The case began when remains were discovered along Ocean Parkway in 2010 and ended with a guilty plea that brought families more than a decade of waiting to an emotional close. Sentencing is set for June 17.
Rex Heuermann, 62, a Long Island architect from Massapequa Park, pleaded guilty on April 8, 2026 to murdering seven women and admitted in open court to killing an eighth. The Gilgo Beach serial killings — one of Long Island's most haunting cold cases — reached a stunning legal conclusion in a packed Suffolk County courtroom in Riverhead, more than 16 years after the first remains were found.
Heuermann stood before Suffolk County Court Judge Timothy Mazzei and admitted to strangling eight women over a span of 17 years. He pleaded guilty to seven of the murders and admitted — though not charged — to an eighth. As he described the killings, victims' family members in the courtroom wept openly. Some had waited over a decade for this moment.
According to prosecutors, Heuermann strangled each victim, then bound their heads and legs and wrapped their bodies in burlap before disposing of them. He agreed, as part of his plea deal, to cooperate fully with the FBI's behavioral analysis unit to help identify other serial killers.
Sentencing is scheduled for June 17, 2026. Prosecutors are seeking life in prison without the possibility of parole, plus three consecutive life sentences and four 25-years-to-life sentences.
The eight women Heuermann admitted to killing ranged in age from 20 to 28 at the time of their disappearances. Their remains were found scattered along the barrier island coastline and in other remote locations:
All eight were targeted while working as sex workers. Prosecutors say Heuermann led what Suffolk County DA Raymond Tierney called "a secret life as a serial killer" — commuting from his Midtown Manhattan architecture office by day while hunting victims at night.
The case broke open in December 2010 when a police officer searching for a missing woman along Ocean Parkway stumbled on human remains near Gilgo Beach. What started as a search became a grim excavation. Over the following months, investigators recovered the remains of ten people along that desolate stretch of barrier island — four of them later identified as the "Gilgo Four": Barthelemy, Waterman, Costello, and Brainard-Barnes.
The case went cold. Years passed with no arrests, no suspects named publicly, and the families of the Gilgo Four living in a painful limbo. The case earned national attention and eventually inspired a Hollywood film.
For Long Islanders, Ocean Parkway would never look quite the same.
The break came from a discarded pizza crust.
Investigators with the newly formed Gilgo Beach Homicide Investigation Task Force obtained DNA from a slice of pizza Heuermann threw away, which matched DNA found at crime scenes. Combined with burner phone records that placed him near victims around the times of their disappearances, and a witness tip about a distinctive vehicle, authorities had enough.
Rex Heuermann was arrested on July 13, 2023, outside his Midtown Manhattan office. He was a licensed architect who had lived in Massapequa Park with his wife and children — a quiet Nassau County suburb that, for residents, made the news feel impossibly close to home.
Heuermann was initially charged with three murders. More charges followed as investigators continued to build the case. By the time he appeared in Riverhead on April 8, 2026, he faced charges tied to seven of the eight women he ultimately admitted killing.
His wife filed for divorce after his arrest. He has been held without bail since July 2023.
The plea hearing lasted approximately 30 minutes. The courtroom was standing room only.
Melissa Cann, sister of victim Melissa Barthelemy, spoke outside the courthouse after the hearing.
"Today is about the women's lives who were stolen," she said. "About their voices, their future, their families."
Suffolk County DA Raymond Tierney addressed reporters alongside victims' family members and task force investigators. "He thought that by killing them he could silence them forever and get away with murder," Tierney said. "But he was wrong."
For the families, the plea does not undo 16 years of not knowing — but it ends the uncertainty of a trial that could have stretched years further.
Heuermann will be formally sentenced on June 17, 2026 at Suffolk County Court in Riverhead. The expected sentence — life without parole — means he will never leave prison.
As part of his cooperation agreement, Heuermann will work with FBI behavioral analysts, potentially helping investigators understand how serial killers operate and avoid detection for so long. That cooperation raises questions no one on Long Island has fully processed yet: were there other victims? Could there be other cases?
The Gilgo Beach Homicide Investigation Task Force, widely credited with finally cracking a case that stumped law enforcement for over a decade, will continue its work. Investigators have said publicly they believe additional unidentified remains found along Ocean Parkway may be connected to other perpetrators.
For Long Island, the guilty plea is a chapter closing — but not the whole book.
