Kenneth Bruton was leaving a grocery store when he got into his truck, looked back, and saw the tornado coming over a hill.

“I got out of my truck and started running for cover,” Bruton told KARK. The force of the wind knocked him down on his face, he said, but he was able to make it to a room.

“And when I walked in, huddled against the concrete barrier, all the glass windows blew out and people flew out,” Bruton said. “And I endured. And it must have been a minute just snuggling. I thought I was lost for sure.»
