Defense Challenges DNA Evidence in Gilgo Beach Serial Killer Case

Hidden Killers With Tony Brueski | True Crime News & Commentary

Rex Heuermann, the alleged Gilgo Beach serial killer charged with murdering seven women, is challenging key DNA evidence ahead of his trial. His defense team is urging the judge to exclude nuclear DNA results derived from hairs found at six crime scenes, arguing the scientific methods used are unreliable.
The case, which has captured national attention, hinges on evidence gathered by the Suffolk County District Attorney's office and the Gilgo Beach Task Force, led by DA Ray Tierney. Heuermann, an architect, husband, and father of two from Massapequa Park, denies involvement in the killings.
Tierney addressed the defense’s motion, saying, "We're not going to engage in what ifs. Obviously, that's among many other key components of our case, so we're prepared to defend it."
Heuermann's attorneys filed the motion in Central Islip this week, asserting that the DNA technique employed by Astrea Forensics, a California-based lab, lacks widespread acceptance in the scientific community. This motion initiates pretrial hearings to determine whether the evidence will be admissible at trial.
"If we weren't confident in the efficacy and the admissibility of that evidence, we would not have used it," Tierney stated.
Prosecutors believe the DNA evidence ties Heuermann to the alleged crimes. Successfully excluding the evidence could weaken the prosecution’s case. However, Tierney expressed readiness for the challenge, adding, "We’ll abide by the mandates of the court, we’ll have the hearing, and we’re looking forward to doing so."
The hearing on the DNA admissibility is set to occur this winter. Depending on its outcome and the time required to address other challenges, the trial could begin later this year or early 2026.
Heuermann, who was arrested last year, is also suspected in other unsolved murders connected to Gilgo Beach. However, Tierney clarified, "We don’t make any assumptions, we just continue to work the evidence and see where that evidence leads."
The next court date for Heuermann is January 15, where further developments in the case may unfold.
