Investigators in the Gilgo Beach serial killer case have made a significant discovery, with a DNA match connecting Asa Ellerup, the estranged wife of prime suspect Rex Heuermann, to the crime scene. Law enforcement sources informed ABC News that a cheek swab from Ellerup matched DNA found on the victims’ remains. Ellerup’s hair was previously identified on the burlap wrapping the bodies discovered near Gilgo Beach, Long Island.
Despite this DNA match, prosecutors have exonerated Ellerup, confirming she was away during the murders. Heuermann, accused of killing three women – Melissa Barthelemy, Amber Costello, and Megan Waterman – has pleaded not guilty to the charges. He remains the main suspect in the murder of Maureen Brainard Barnes, another Gilgo Beach victim. Additionally, DNA from Heuermann matched genetic material on a pizza box found near his office, further implicating him in the crimes, as per the Suffolk County District Attorney’s office.
