Accused LISK Rex Heuermann's Hair DNA May Never See A Jury, Here's Why

In this episode, we break down the high-stakes legal battle playing out in the Rex Heuermann case—accused in the chilling Gilgo Beach serial murders. At the center of it all? A motion to exclude groundbreaking DNA evidence derived from hair samples found on the victims. With no roots, no blood, and no traditional genetic markers, these hair fragments were analyzed using whole genome sequencing, a method never before used in a New York criminal trial. Prosecutors say the science is solid. The defense calls it “magic.”

You’ll hear exactly how this forensic evidence was gathered, what it allegedly reveals about Rex Heuermann and his household, and why both sides are fighting tooth and nail over its admissibility. We explore the role of Astrea Forensics, the lab behind the testing, and the legal implications of introducing this type of DNA evidence into court. As the Frye hearing unfolds, experts are taking the stand, and even Jurassic Park has made its way into the courtroom. Yes, really.

We also examine the defense's strategy to sever the murder charges—arguing that trying all seven cases together would unfairly sway a jury. With the structure of the trial and the admissibility of DNA evidence both hanging in the balance, this case could set a major precedent for how forensic science is used in court. If you're following the Gilgo Beach murders or the Rex Heuermann trial, this is an episode you won't want to miss.
