Derrick Owens was 30 when he was fatally shot on April 24, 2015. He was standing outside his vehicle in the 1300 block of Columbus Avenue in Pittsburgh around 10 p.m. at the time he was shot. Owens was married and left five children, aged between 5 and 12.

The case record notes that Rashawn Austin, 28, of Bellevue, was later arrested and convicted in connection with the killing. The trial included contested eyewitness testimony and questions about how eyewitness accounts fit with physical evidence, issues highlighted during the proceedings.

What can anyone who knew Derrick or who was in the neighborhood that night add about his last movements or about activity on Columbus Avenue around 10 p.m.?
