A male hair had been found on the burlap used to wrap one of the victim's bodies before he dumped her along Gilgo Beach. In 2010, when it was discovered, DNA wasn't advanced enough to analyze it, but 10 years later it was tested and a DNA profile came back. To see if it matched the killer, investigators nabbed a pizza box that he chucked into the trash near his office. Inside, they found leftover pizza crust. Last month, the forensics came back. It was a match.
