Three people police believe are responsible for a shooting outside a pawn shop in Thornton were caught on surveillance video, and now authorities are hoping the public will help identify them.

A person was shot outside the Sulzbacher shelter on East Adams Street just before noon last month. Police say the man pictured is responsible, but still on the loose.

DC Police found a man unconscious and not breathing at the bottom of the escalator leading to the waiting area at Union Station after reports of a shooting around 4:47 p.m. Monday. Despite the efforts of first responders, the man was declared dead on the scene. Police have since identified the victim as 18-year-old Wayne McDaniel.
