Correspondent Erin Moriarty revisits the case, revealing disturbing new details about Heuermann’s background and behavior. Moriarty has been covering the Gilgo Beach murders since 2010, and in this episode, she features an exclusive interview with Muriel Henriquez, a former colleague of Heuermann at his company, RH Consultants & Associates. Henriquez recalls unsettling interactions with Heuermann, including a chilling moment when Heuermann’s tracking skills unnerved her during a vacation, as he eerily claimed he could find her anywhere—even in the middle of the ocean.

This episode marks the sixth edition of 48 HOURS‘ investigation into the Gilgo Beach serial murders. Over the years, the program has featured multiple exclusive interviews, including with Dave Schaller, Amber Costello’s roommate, who provided a key description of Heuermann and his vehicle.
