placing her shopping cart in the back drives off. greenwell follows behind her and when she appears back in the window, it's a moment of mutual confusion. >> she turned and saw me. we made eye contact. >> no. oh, my god. >> i could see her making motions. she was talking to herself. obviously i didn't know what she was saying. maybe she was shocked that the police were so quick because i was that it was her in the vehicle. >> when he flashes his lights, the suspect pulled over. >> the vehicle pulled over on the shoulder. we pulled behind it in basically textbook fashion. i gave her verbal commands. for the most part she obeyed commands. >> let me see your hands. open up the door. keep your hands visible. stay right there. turn around.
