She saw them, could I.D. them, that was enough to get her shot. The first deputy likely ran in like a bull in a china shop, and wasn't paying attention. Too much testosterone can be lethal.
Yeah, could be, but more likely she was the target. I would think that guys waiting for the sheriff would know when he was apt to be home and would also have some inkling as to when his wife would be home, especially if she could ID them.
