An armed "good Samaritan" as the Arlington Police labeled him happened to be eating at the restaurant with his wife. A concealed carry permit holder, he told her to get down on the ground and then shot Jones in the back.
"I dont think the shooter even knew where the rounds were coming from because he started shooting at the front door," Cook said, who described the scene as "chaotic."
Police reviewed video surveillance and pieced together the incident via witness interviews, but it remains unclear how many shots were fired by either individual. Police were looking into Jones background to see whether he suffered from any mental illnesses and were awaiting test results to find out if he was under the influence.
