They talk about Kathryn’s sharp mind, bold choices, and how she planned a headline-making kidnapping and even called J. Edgar Hoover herself.

  • Karen Read Retrial | Panel Unpacks the Case That Shattered Public Trust
    Jun 16 2025

    In this episode of Zone 7, Crime Scene Investigator, Sheryl McCollum, brings together a powerhouse panel including Susan Hendricks, Joshua Schiffer, Dani after Dark, and Kirk Nurmi to break down the second trial of Karen Read, and it’s more than just a courtroom drama. They unpack how the defense pivoted from conspiracy to collision, why the prosecution’s own reenactment may have backfired, and how key testimony created more questions than answers.

  • Crime Round Up with Nancy Grace: 6.13.25 | Who Tells the Story of the Victims?
    Jun 13 2025

    Today Nancy Grace and Sheryl McCollum get personal, powerful, and just a little bit poetic. From a town mourning its unlikely mascot to Nancy’s candid reflections on personal tragedy, the conversation explores how loss, both individual and shared, shapes the pursuit of justice. They examine the impact of victim-centered storytelling, particularly in the upcoming One Night in Idaho docuseries, and how it reframes our understanding of crime and accountability. Plus, they break down the Dateline leak that’s stirring controversy ahead of the Bryan Kohberger trial. Who leaked it, and why does it matter? The answers may be more complicated than you think.
