Gilgo Beach serial killer Rex Heuermann sentenced to life in prison without parole

Rex Heuermann, the Long Island architect who spent nearly two decades murdering women and leading a double life in his family’s suburban home, was sentenced Wednesday to life in prison without the possibility of parole for the Gilgo Beach serial killings, a case that haunted New York for three decades.

Suffolk County Judge Timothy Mazzei delivered the sentence in a Riverhead courtroom packed with victims’ families, who delivered emotional impact statements before Heuermann, 62, briefly addressed the court. When the judge pronounced the sentence, the courtroom filled with applause and cheers, according to reports from inside the hearing.

“You are a disgusting, despicable and small man, and you are a coward,” Judge Mazzei said before handing down the sentences.

Under the terms of his plea agreement with Suffolk County prosecutors, Heuermann received three consecutive life terms without parole for the murders of Melissa Barthelemy, 24; Megan Waterman, 22; and Amber Lynn Costello, 27 — three of the women known as the “Gilgo Four” — plus an additional consecutive sentence of 100 years to life for the killings of Maureen Brainard-Barnes, 25; Jessica Taylor, 20; Sandra Costilla, 28; and Valerie Mack, 24. The death of Karen Vergata, 34, whose 1996 murder had not previously been linked to him, was also covered under the agreement.

Heuermann pleaded guilty in April to seven of the murders and admitted to an eighth, confessing that he strangled each woman to death. As part of his deal, he agreed to cooperate with the FBI’s Behavioral Analysis Unit to assist in identifying other serial killers.

Prosecutors say all but one of his victims were murdered in a basement “kill room” in the family’s Massapequa Park home while his wife and two children were away. Investigators later recovered a planning document from a hard drive in the basement that detailed a meticulous four-day kill plan — including timing how long it took to dispose of bodies and notes for cleaning up afterward. Some victims were dismembered and wrapped in burlap before their remains were dumped along desolate stretches of Long Island, where police began discovering them in December 2010.

The killings spanned 1993 to 2010, but the cases went unsolved for years. The investigation was reopened in 2022 after former NYPD Chief Rodney Harrison became Suffolk County police commissioner. Heuermann was arrested in July 2023 outside his Manhattan office — in part because of DNA recovered from a pizza crust he had discarded in the trash — and initially charged with three of the cold-case killings. DNA evidence subsequently linked him to four additional victims, with an eighth connection emerging later.

His attorney, Michael Brown, has said Heuermann was not involved in two other Gilgo Beach-area deaths — those of Shannon Gilbert, a sex worker who disappeared in 2010, and an unidentified victim known as “Asian Doe.”

Heuermann has been held in solitary confinement at the county jail in Riverhead since his arrest and will now be transferred to a state prison to be determined. Suffolk County Sheriff Errol Toulon said the convicted killer spent his pretrial years reading crime novels and striking up a brief correspondence with Keith Jesperson, the “Happy Face Killer,” who is serving a life sentence in Oregon.

Outside the courthouse ahead of the sentencing, a group of sex workers rights advocates gathered dressed in red and carrying red umbrellas and protest signs. “STOP mythologizing men who kill sex workers,” read one sign. Another declared: “Sex workers are not a social ill, violent men are.”
