A 29-year-old veteran used a stolen truck to drive critically injured victims to safety during what quickly became the deadliest shooting in U.S. history. 
Taylor Winston, a Marine veteran from San Diego, was among friends at the Route 91 Harvest festival in Las Vegas Sunday night when a gunman from a nearby hotel room opened fire on the audience. Winston told CBS This Morning he was dancing the two-step with his girlfriend just moments before. Once Jason Aldean stopped playing and the stage went dark, he realized popping sounds he first thought were fireworks were actually rapid-fire bursts of gunfire.
After climbing over a fence to safety, Winston and a friend looked for ways to help those still in danger. Winston checked nearby trucks for keys.
