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 in the heart of Texas oil country more than 300 miles (483 kilometers) west of Dallas. At one point, he hijacked a mail carrier truck, killing the lone postal worker inside.
