From NBC:

Officers responded to a busy intersection Tuesday after receiving reports that a man was throwing rocks at vehicles, according to Police Chief Bob Metzger of the Pasco Police Department.

Metzger said Antonio Zambrano-Montes threw at least one “softball size” rock and did not respond to the officers’ orders to put down the projectiles. He said officers deployed a Taser, but that it had no effect on Zambrano-Montes.

One witness on the scene told the Tri-City Herald that the use of deadly force shocked him, saying, “I really thought they were just going walk up and tackle or tase him, but they opened fire. His back was turned.”

This is the fourth fatal police shooting in Pasco in the last six months.
