Interesting. I’m wondering if she threw the keys out the window because she didn’t want him driving in his state of mind. That’s what I would have done. It does not bode well that he left the scene. Methinks there were drugs involved.
That’s always a possibility. As far as the bite marks, perhaps it was because she had the keys but hadn’t tossed them yet. It’s wrong, no matter what the reason; just thinking out loud.
