While Corona was responding to a multi-car collision, the suspect rode up on a bicycle, in the shadows, and opened fire.
"This clearly to us was an ambush," said Davis Police Chief Darren Pytel.
He hit Officer Corona once, and she fell to the ground, police said.
Then, the suspect continued shooting her, unloading an entire magazine.
