Could someone have finally given information to the police that had to do with her wanting to "go off the radar" for a bit? You know, maybe she wanted to shake up the bf a little, tell him she is coming home, but then not show up; make him worry. Send that last text, shut her phone off, and make him sweat. Maybe she said something to her walker friend and it was confirmed by another friend and that's why they don't think of him as a POI. LE keeps saying they don't know how she left the garage. But maybe they now know she left voluntarily, with whom they don't know. If something happened to her after that, they don't know. Maybe she did have another phone and used that to contact someone to pick her up. Maybe she waited a day and then had this other person drive her to Fort Worth and surprised her bf. If he was with someone else it could've been ugly.
Just throwing ideas out there. I know we've talked about this a million times, but still...
