29-year-old Lindsay Padgett thought the loud popping sounds that interrupted Jason Aldean's performance were just part of the show - until people started screaming to 'get on the ground.' "I thought for sure we were all going to die," she told ABC News. When the gunshots briefly subsided, Padgett and her fiance, Mike Jay, fled the scene unharmed and fetched their truck. "We realized there were people everywhere that needed help and on stretchers... People saw that we had a truck, so we said, 'Fine, yeah,' and started to pack everyone in." On their way to the hospital, with 10 people on their backseat, they encountered a stopped ambulance and handed off their most critically injured passengers. They then continued on to bring the rest to the emergency room. "We were ready to go back and get more people, but my cousin called me because they were scared... So we went there to get my cousin and my family."
