In Season 1 of "Longshot," "Return Man" is an investigation into the life and mysterious death of the only Super Bowl champion from Lancaster, S.C. In 1970, Jim Duncan was a star on the rise for the Baltimore Colts, and the top kickoff return man in the NFL. Then, two years later, authorities say Duncan, who was Black, died of a self-inflicted gunshot wound inside his hometown police station. Many Black people alive in Lancaster at the time didn't believe the official account of the death. They also didn't openly question it. Until now.
