Zone 7 with Sheryl McCollum

In this episode of Zone 7, Sheryl McCollum is joined by Caroline McCollum and Huck McCollum to talk about the case involving three horses who were stabbed during a barrel racing event at South Point Casino in Las Vegas. Caroline, a longtime horse rider and criminology student, shares her perspective on what it means to compete with and care for these animals, and how the open, trusting culture of barn life can become a vulnerability. Huck, a juvenile court intake officer and former public defender investigator, explains how a case like this may move through the justice system, including mental health evaluations, prior behavior, and the role social media could play. Together, they look at the trauma this leaves on both riders and horses, the security gaps it exposes, and why animal cruelty cases raise concerns about future violence.
