As the opening salvo hit the crowd, Winston and Lewis ran for cover, but they didn't flee the scene. Once Jason Aldean stopped playing and the stage went dark, he realized that the popping sounds he first thought to be fireworks were actually rapid-fire bursts of gunfire. Moments later, the gunfire began.
"People started scattering and screaming and that's when we knew something real was happening", Winston told CBS This Morning.
After climbing over a fence to safety, Winston and a friend looked for ways to help those still in danger. Yet we were a few yards away from getting hit by bullets, literally a couple of feet away. Once he landed on the other side, he said he reportedly saw a bunch of white trucks. "We were looking back and people were going down everywhere, it was pretty bad".
The 29-year-old marine veteran knew he had to help. The first truck he opened had keys sitting inside. There was far too many causalities for anyone to handle.
By the end of the night, Winston and his friends would transport two-dozen people to the hospital.

He left the Corps in 2011 as a sergeant.
"Taylor Winston, you are a hero". He said he saw many people - like him - doing good deeds.
"There's a lot of unsung heroes that day that stood up and helped people". They wanted to go back and pick up more but Padgett got a call from her scared cousin who was also at the concert with other family members.
Winston says he is just 100 percent lucky that he was not injured or killed.
Winston has since returned the keys of the truck to the owner.
