Sandra Costilla: How Rex Heuermann Was Linked to 1993

Before Melissa. Before Megan. Before Amber. Before any of the women we came to know as the Gilgo Four — there was Sandra Costilla. Found in the woods of Southampton in November 1993. Twenty-eight years old. From Trinidad and Tobago. And for thirty years, completely disconnected from the Gilgo Beach investigation. Prosecutors say that was a mistake — and that advanced DNA evidence now links her to Rex Heuermann with near-certainty.Episode 1 of "The Seven" — a seven-part series covering each woman Heuermann is charged with killing. Sandra's case rewrites the entire timeline. If the prosecution is right, this didn't start in 2007 with Maureen Brainard-Barnes. It started in 1993, when Heuermann was 30 years old and years away from the family life prosecutors say he used as cover.The defense called the evidence "a single hair on a shirt." The prosecution called it a 99.96 percent DNA match. The judge ruled it admissible. The evidence, the wrong suspect, the cold decades, the forensic breakthrough, and what a seven-year gap between Sandra and the next known victim might mean — all of it covered here. This is the foundation of the series.Join Our SubStack For AD-FREE ADVANCE EPISODES & EXTRAS!: https://hiddenkillers.substack.com/Want to comment and watch this podcast as a video?
