The attack began Saturday afternoon when Texas state troopers tried pulling over a gold car on Interstate 20 for failing to signal a left turn. Before the vehicle came to a complete stop, the driver “pointed a rifle toward the rear window of his car and fired several shots” toward the patrol car stopping him, according to Texas Department of Public Safety spokeswoman Katherine Cesinger. The gunshots struck a trooper, Cesinger said, after which the gunman fled and continued shooting. He fired at random as he drove in the area of Odessa and Midland, two cities more than 300 miles west of Dallas.
