Police: Rookie Texas officer shoots at dog, kills woman

A rookie Texas police officer accidentally shot and killed a woman behind a shopping plaza when he fired repeatedly at a dog believed to be hers that was running at him, authorities said Friday.

The officer in the Dallas suburb of Arlington, who was released from supervised duty on July 1, responded to a welfare check Thursday about a woman who appeared to be passed out in a grassy area behind the plaza.

Footage from the officer's body-worn camera released Friday shows the officer walking along a sidewalk and calling out, "Hello. Are you OK?" The woman replies, "Yeah, I'm fine."
