About

Sandra Costilla was a 28-year-old sex worker from Queens, New York whose partial remains were found along Ocean Parkway near Gilgo Beach in November 1993 — predating the 2010 discoveries by nearly two decades. Her case remains separate from the 'Gilgo Four' victims, though investigators have examined whether she was also a victim of Rex Heuermann. Costilla's identification took years because of the fragmentary nature of her remains.

Gilgo Beach Serial Killings

The Gilgo Beach serial killings involved the murders of at least eight women whose remains were discovered along Ocean Parkway on Long Island, New York, beginning in December 2010. Rex Heuermann, a 59-year-old Manhattan architect, was arrested on July 13, 2023, after DNA from discarded pizza crust linked him to evidence found with the victims. On April 8, 2026, Heuermann pleaded guilty to seven murders and admitted to an eighth, with sentencing scheduled for June 17, 2026.
