A driver pulled up behind a San Antonio police officer as he sat in his squad car writing a ticket on Sunday, walked to the driver's side window, and pulled the trigger, shooting the 20-year police force veteran in the head the Associated Press reports:
San Antonio police Chief William McManus said the suspect is not known and has not yet been apprehended. A motive is not known.
"This is everyone's worst nightmare," he said.
The officer was transported to the hospital and was pronounced dead shortly thereafter. What makes the crime particularly bold is that the officer was sitting in front of police headquarters at the time of the shooting.
The officer-targeted shooting comes only months after high profile officer killings in both Dallas and Louisiana, and mere weeks after two officers were shot and killed in Des Moines, Iowa.
Texas Governor Greg Abbott called the shooting a "horrific act of violence" and promised swift justice for any attacks made against law enforcement in the state of Texas.
