ZONE 7: Procedural Chaos: Inside the Mangione Hearing That’s Putting Police Training on Trial

In this week’s Crime Roundup, Sheryl McCollum and Joshua Schiffer Break down the federal hearing surrounding Luigi Mangione, the suspect accused of assassinating UnitedHealthcare CEO Brian Thompson in December of 2024.  What began as a five-day manhunt has become a master class in what not to do, with missed warrants, coached testimony, and evidence on the verge of being thrown out. Sheryl and Joshua examine how procedural missteps could weaken a potential death penalty case and why “get a warrant” isn't just good advice; it's the foundation of justice. They then turned their attention to Massachusetts, where the trial of Brian Walshe, who is accused of killing and dismembering his wife, reveals how arrogance, lies, and a trail of Google searches can expose a killer's truth.
