As officers arrived and contacted the occupants of the residence to investigate, Santos emerged from a back room of the residence with a semi-automatic rifle and began firing at officers. The officers were able to retreat, as fired multiple shots at officers and their marked police vehicles from two semi-automatic rifles and one officer was able to return fire and struck the Santos.
