In this week’s episode of Zone 7, Sheryl McCollum talks to Court TV correspondent Matt Johnson about what it takes to cover high-profile criminal cases and trials, from the Lori Vallow Daybell case and Rex Heuermann to Karen Read and the Delphi murders. Matt explains how deadlines, jury reactions, and the pressure of live television shape the way he turns hours of courtroom testimony into clear, accessible coverage. They discuss the public’s fascination with true crime, investigative missteps, and the emotional weight of sitting near violent offenders, including a moment when Matt says it felt as if “the devil is real, and here he is.
