Others who were there later told him it sounded like four or five people were shouting. He thinks maybe an angel was standing behind him and speaking through his voice. When the shooter ran, he immediately gave chase.

Stewart, 51, told The Daily Caller on Sunday he doesn’t remember any conscious thought from the moment he heard the gun shots until it was all over — he just acted on instinct to stop the shooter and prevent him from leaving so he couldn’t hurt more people somewhere else. The Iraq combat veteran said his military training kicked in.

“I knew I had to be within five feet of this guy so his rifle couldn’t get to me,” Stewart said. “So I ran immediately toward him, and I yelled as loud as I could. And he was scared. I scared the hell out of him.”
