Looking at street view, I'd really love to know where her car was parked in the lot at Walmart. If it was parked along the side or the back, it feels more like it was dumped there, but parking out in BFE towards the road seems more like it could have been Tina meeting up with someone voluntarily. It would be really nice to know if anyone noticed the car the night she went missing or if it just showed up randomly closer to the time it was found.
I also have so many questions about her leaving. Was this a mid-dinner bolt? Were they just socializing after eating? Did she seem nervous, stressed, happy, excited, mad?
