Nancy Guthrie Case: We Need to Start Fresh

In this week’s episode of Zone 7, more than three months after Nancy Guthrie vanished, Sheryl McCollum returns to the case with one central question: what does the evidence actually prove? From the masked suspect’s behavior on camera to the blood patterns at the front door and the complete absence of credible ransom activity, she argues that the scene shows signs of staging, not a financial motive, and makes the case that investigators may need to reset and start again from the ground up.
