A manhunt was underway on Sunday for a gunman who shot and killed a San Antonio police officer sitting in a squad car during a routine traffic stop outside the Texas city's police headquarters, authorities said, Reuters reported.
The shooting unfolded when a second vehicle pulled up behind the parked patrol car, San Antonio Police Chief William McManus said. Its driver exited and fired two shots through a window, hitting the officer as he filled out a traffic ticket.
The suspect sped away from the scene in a black car, driving through the parking lot that serves the San Antonio Public Safety Headquarters on the western edge of downtown.
"A person pulled up behind the patrol car in a black vehicle, got out, walked up to the passenger window, fired one round, shooting the officer in the head," McManus told reporters near the scene of the shooting. "He then reached in and fired a second round, shooting him a second time."
McManus said he did not know if the motorist who was pulled over for the traffic violation was connected in any way with the man who shot the officer, a 20-year veteran of the force.
The chief said police were looking for an African-American male wearing a hoodie and black pants, whose image was captured by security cameras.
