New York architect Rex Heuermann, accused in the Gilgo Beach murders, faces a 7th charge for Valerie Mack, whose remains were found in 2000 and 2011. Arrested in July 2023, Heuermann pleads not guilty. Investigators used DNA, cell phone data, and internet searches to link him to 11 victims. Mack’s case involved DNA matching his daughter’s profile. Heuermann’s trial is scheduled for 2025.
