On April 24, 2020, an argument in a northeast Denver parking lot near the AutoZone at Green Valley Ranch Boulevard and Chambers Road ended with Arthur Jerome Robinson Jr., 36, shot in the back. Known as Pugs to family and friends, he was a father and worked in community corrections. Witnesses saw Robinson run from the dispute as another man pursued him and fired a single shot that struck his back, damaging his heart and a lung. He was taken to a nearby hospital and died of his injuries.

Denver police located the vehicle used to flee the scene and interviewed its registered owner, and a witness identified 51-year-old Samuel J.P. Robinson in a photo lineup. Samuel Robinson was arrested later that day at a home about a half-mile from the shooting and charged with first-degree murder and possession of a weapon by a previous offender. The defense at trial said the shooting was accidental, but a jury convicted Samuel Robinson of second-degree murder.

Did anyone in the Green Valley Ranch area witness the argument or the vehicle leaving the scene that morning?
