A veteran Bexar County sheriff's deputy was fatally shot during an apparent ambush while waiting at a traffic light in his marked patrol vehicle early Saturday, according to the San Antonio Express. Forty-five-year-old Sgt. Kenneth Vann was waiting at an intersection just after 2 a.m. Saturday when a small white vehicle pulled up next to him on the right side and started shooting through the front passenger window. Witnesses called police, who discovered Vann dead in the driver's seat.
