The officer did a U-turn and then all three ran. He drove through streets following them and then chased them on foot. He then got into a physical confrontation with one that escalated into gunfire. The teenager had a gun and fired at least three shots at the officer, who returned fire, the chief said. The teenager attempted to fire more but his gun jammed, Dotson said.
