I wonder how clear the CCTV is of the moment he breached her car -- the advantage of ambush coupled with any threat of a weapon, real or otherwise, visible or otherwise, would be hard to process. She may have moved because he was already forcing his way in. You get one second to react but not really because the oppressor is forcing the moment.
I wonder what evidence in the vehicle indicated foul play. Blood, taser dart, that's what come to mind for me.
He had full and immediate control, from the sounds of it.
May today bring in the tip they need.
