  • Nancy Guthrie Missing: Blood, Bitcoin, and a Story That Doesn’t Add Up
    Feb 10 2026
    When 84-year-old Nancy Guthrie disappeared from her home, investigators were quickly faced with blood evidence and ransom claims that did not align with standard abduction patterns. In this episode of "Zone 7," Sheryl McCollum, retired NYPD homicide detectives Dan Murphy and Tom Smith, and forensic pathologist Dr. Priya Banerjee assess why blood at the scene, a prolonged presence inside the home, and Nancy’s medical vulnerabilities undermine the ransom narrative. The panel also examines investigative decisions and evidence handling that may shape accountability. For those looking to stay informed as the situation develops, additional coverage and updates can be found on "Crime Stories with Nancy Grace." Enjoying "Zone 7"?

  • A Missing Teen and a High-Profile Arrest: The Evidence, Silence, and Selective Claims with Guest Lauren Conlin
    Feb 4 2026

    An active investigation into the death of 14-year-old Celeste Rivas Hernandez has left the public with a timeline, a Tesla, and an extensive list of unanswered questions.

    In this episode of "Zone 7," Sheryl McCollum is joined by journalist Lauren Conlin to review what has been said publicly about Celeste’s initial classification as a runaway, her connections to older individuals, and why the continued absence of a named person of interest raises concern.

    They also turn to the arrest of actor/director Timothy Busfield and discuss what can and cannot be concluded from selective “evidence” releases, how credibility gets weaponized in public, and why child abuse allegations demand careful, methodical evaluation rather than internet verdicts.

  • Louvre Royal Jewels Heist: How Thieves Pulled Off an Eight-Minute Museum Hit
    Jan 28 2026

    In broad daylight on October 19, 2025, thieves dressed as construction workers targeted the Louvre and vanished with $100 million in royal jewels in about eight minutes.

    In this episode of "Zone 7," Sheryl McCollum is joined by former jewel thief Bryan Sobolewski to lay out exactly how a heist like this gets pulled off, what mistakes crews make when the clock is ticking, and why modern forensics can turn a “perfect” job into an evidence trail.

    Sobolewski then shares his own history, the losses, and long-term consequences, and why he now speaks publicly to warn others away from choosing a life of crime.
