Karmelo Anthony was convicted of murdering 17-year-old Austin Metcalf during an altercation at a high school track meet and was sentenced to 35 years in prison. Anthony’s defense team sought a new trial, and hearings this week revealed that prosecutors and the defense had agreed to keep certain evidence from the original jury.
In this episode of Zone 7, Sheryl McCollum is joined by civil litigator Reagan Charleston Thomas to discuss what that newly disclosed information could mean for the case. They look at the agreement between prosecutors and the defense that kept information about both teenagers out of the original trial and the strategy behind that decision. Sheryl and Reagan also discuss the Nolan Wells case and the dispute over access to his phone before reacting to Judge Michael Chitty’s ruling denying Karmelo Anthony’s motion for a new trial.
