The former architect from Manhattan, Rex Heuermann, will face sentencing Wednesday for his role as the Gilgo Beach serial killer. Heuermann admitted to killing eight women, closing a dark chapter for the Long Island community that lasted nearly two decades.
Heuermann is expected to receive multiple life sentences in the Riverhead, New York court at 9:30 a.m. Both he and the victims’ families will have a chance to speak during the proceedings.
In April, Heuermann pled guilty to charges related to seven murders, acknowledging his role in the death of an eighth woman, Karen Vergata. Due to a plea agreement, he was not charged with Vergata’s murder.
Victims include Melissa Barthelemy, Maureen Brainard-Barnes, Amber Costello, Sandra Costilla, Valerie Mack, Jessica Taylor, Karen Vergata, and Megan Waterman, according to Suffolk County Police.
Living in Massapequa Park, a suburb about an hour from Manhattan, Heuermann was apprehended in 2023. Evidence such as DNA from a discarded pizza crust in Manhattan was crucial. This arrest revived a case that had long puzzled investigators and distressed the victims’ families.
He was charged with the murders of Melissa Barthelemy, Megan Waterman, and Amber Costello, who went missing in 2009 and 2010. These women, all sex workers, were found in Gilgo Beach in 2010, with their bodies wrapped in burlap.
In 2024, Heuermann was also charged with killing Maureen Brainard-Barnes. Further charges were brought for the deaths of three other women whose remains lay along the beach parkway: Jessica Taylor, who vanished in 2003; Sandra Costilla, found deceased in Southampton in 1993; and Valerie Mack, missing since 2000.
The discovery of these serial murders instilled fear in Long Island’s inhabitants. This bustling suburb with a mix of middle-class and affluent families includes many professionals commuting to New York City. The case’s resolution provides relief to a community that has grappled with fear and grief for years.
