  • 4.11.25 CRU with Nancy Grace: Will Rex Heuermann’s House Be Demolished? Inside Lori Vallow’s Legal Gamble

    4.11.25 CRU with Nancy Grace: Will Rex Heuermann’s House Be Demolished? Inside Lori Vallow’s Legal Gamble
    Apr 11 2025

    On this episode of "Zone 7," Nancy Grace and Sheryl McCollum discuss the latest developments in the Rex Heuermann and Lori Vallow cases.

    Sheryl checks in live from the Hamptons, describing the quiet tension in a neighborhood trying to move on. She talks about Rex Heuermann’s house, now partially hidden as the family packs up and prepares to leave. Nancy and Sheryl question what this move means—whether it’s the first step toward tearing the house down—and why that could pose a problem for the trial.

    They stress the importance of jurors seeing the space where the crimes occurred to fully understand the case.

    Nancy then shifts to the latest on Lori Vallow. Representing herself, Lori faces charges for the murders of her children and former husband.

    Nancy and Sheryl walk through the case and explain how Lori’s unusual behavior and beliefs played a role in the crimes.

He talks openly about his early life in Chicago, his attempts to pursue a professional life in acting, and the psychotic break that led to a series of brutal murders in the Atlanta area.
