A man shot and killed himself at Houston’s Bush Intercontinental Airport Thursday after causing a disturbance by firing shots into the air inside one of the terminals. A McDonald’s employee says she saw the whole thing: “As soon as he walked in, he just automatically started shooting quickly. And we hear two shots and we just automatically started running. We ran all the way to the back.” Officials say the man fired an AR-15 rifle twice, and then an air marshal fired at him, but missed. He then pulled out a pistol and shot himself in the head.
