A Long Island architect who led a secret double life as one of America’s most prolific serial killers has been sentenced to life in prison without parole after admitting in court to the murders of eight women, most of them sex workers whose remains lay undiscovered for years on a desolate stretch of highway near New York City.
Rex Heuermann, 62, of Massapequa Park, appeared before a judge in Riverhead, New York, on Wednesday wearing a black suit and blue shirt, and confirmed what investigators had come to believe — that he had strangled his victims and dismembered some of their bodies over a period spanning roughly a decade from the early 2000s.
He had pleaded guilty in April to the murders of seven women: Megan Waterman, Melissa Barthelemy, Amber Lynn Costello, Maureen Brainard-Barnes, Valerie Mack, Jessica Taylor and Sandra Costilla. In court on Wednesday, he also admitted to killing an eighth victim, Karen Vergata, for whose death he was never formally charged. Most of the women disappeared between 2000 and 2010, and most of their remains were found along Ocean Parkway near Gilgo Beach, around 50 miles from New York City.
The case gained public attention in 2010, when investigators searching for a missing sex worker — whose death was ultimately ruled an accidental drowning — began to find other remains in the area. The investigation then went cold for years before a renewed inquiry in 2022 identified Heuermann as a suspect. Detectives linked him to a pickup truck a witness had seen in the area when one of the victims disappeared in 2010, and matched DNA from a pizza crust he discarded in a New York bin to genetic material extracted from degraded hair fragments found on a victim’s remains.
Further evidence included mobile phone tracking data placing him near the disposal sites, and documents retrieved from his computer that prosecutors described as a “blueprint” for the killings, including a checklist with reminders to limit noise, clean the bodies and destroy evidence. He was arrested in July 2023 and had remained largely silent through subsequent court appearances.
As part of his guilty plea, Heuermann has agreed to cooperate with the FBI’s behavioural analysis unit to assist in the identification of other serial killers. According to Suffolk County Sheriff Errol Toulon, Heuermann has spent the past three years in segregated custody at Riverhead county jail, passing the time reading crime novels, receiving occasional visits from lawyers or family, and briefly corresponding with the notorious “Happy Face Killer.”
His ex-wife Asa Ellerup and their two adult children did not attend the sentencing, saying through their lawyers they were staying away out of respect for the victims’ families.
