Theory Briefing

  • Buscando Corazones, a Sonora volunteer search group, followed a tip that Nancy Guthrie was buried near the U.S.-Mexico border — and found nothing.
  • The willingness to pursue unverified leads illustrates how grief-driven hope can override rational evidence-filtering in missing persons cases.
  • Cross-border disappearances create jurisdictional blind spots that make resolution harder and false tips more likely to fill the information vacuum.
