A San Antonio, Texas, police officer writing out a traffic ticket to a motorist was shot to death in his squad car Sunday outside police headquarters by another driver who pulled up from behind, authorities said. San Antonio police Chief William McManus said the suspect is not known and has not yet been apprehended. McManus said the officer had pulled over a vehicle and while he was inside his squad car writing a ticket, a vehicle pulled up behind him. He says the driver of that vehicle got out, walked up to the officer's driver-side window and shot the officer in the head. The mayor of San Antonio issued a statement extending her condolences to the family of the slain police officer and the entire police force.
