Suffolk District Attorney Ray Tierney spoke with News 12 ahead of the one-year anniversary of Rex Heuermann’s arrest in the Gilgo serial killer case.
Tierney revealed that investigators are still combing through evidence. That includes physical evidence and digital evidence. Tierney says Heuermann had hundreds of encrypted smart devices. Detectives are working to access the information on those devices.
The DA also discussed DNA evidence, including nuclear DNA, which Tierney says could only be linked to Heuermann.
Heuermann has been charged in six murders. He is a suspect in a seventh, the killing of Valerie Mack.
