Gilgo Beach Killer Admits to Seven Murders in Historic Plea
Manhattan architectural consultant Rex Heuermann confesses to years-long killing spree targeting vulnerable women on Long Island
Rex Heuermann, a Manhattan architectural consultant, pleaded guilty on April 8, 2026, to seven counts of murder connected to the Gilgo Beach serial killings—one of the most notorious unsolved cases in recent American criminal history. The plea represents a watershed moment in a case that gripped New York for over a decade.
Heuermann, 59, a resident of Massapequa Park on Long Island, admitted to strangling all seven victims and dismembering many of them. During his guilty plea, he also confessed to murdering Karen Vergata, 34, who went missing in 1996—a killing for which he was not formally charged. The eighth victim's remains were partially discovered on Fire Island in April 1996, when her legs washed ashore.
The seven victims he was charged with killing span two decades of violence. Sandra Costilla, 28, was killed in 1993. Valerie Mack died in 2000. Jessica Taylor, just 20 years old, was murdered in 2003. Maureen Brainard-Barnes, 25, was killed in 2007. Three more victims—Melissa Barthelemy, 24; Megan Waterman, 22; and Amber Costello, 27—were all murdered between 2009 and 2010.
The Gilgo Beach killings became a landmark case in serial murder investigations. At least 11 bodies were discovered along Ocean Parkway in Long Island, many of them wrapped in burlap. Many of the victims were escorts or sex workers, a pattern that drew criticism at the time for the relative lack of urgency in the investigation compared to cases involving victims from more affluent backgrounds.
Heuermann was arrested on July 13, 2023, more than a decade after the initial crimes. Law enforcement gradually charged him with the seven murders through 2024. His guilty plea on April 8, 2026, eliminated the possibility of a trial and brought the case to an unprecedented resolution after years of legal proceedings.
