SAN ANTONIO --
Authorities in south-central Texas say a veteran sheriff's deputy was shot and killed while waiting at a traffic light in his patrol vehicle.
Bexar County Sgt. Kenneth Vann was waiting at an intersection early Saturday when someone in another vehicle pulled up next to his marked cruiser and opened fire through Vann's front passenger side window.
Chief Deputy Sheriff Manuel Longoria called it a "senseless" attack. He told the San Antonio Express-News that Vann was struck by a number of bullets and died at the scene.
Investigators don't have a motive for the attack. No arrests have been reported.
Vann had been on the force for 24 1/2 years and was a patrol supervisor. His wife is also a sergeant with the sheriff's office.
