IMO there are really only two outcomes and both make sense to me.
1. She left of her her own free will and while that doesn’t make sense to a lot of people, many woman have done it. And tbh not much about this case makes much sense.
2. She met with foul play.
I truly believe LE has some indication of which of those two scenarios are most likely. The fact they aren’t releasing any new information indicates to me that they have a strong suspicion of what did in fact occur.
Some questions I have:
1. I wonder if her door keys/car keys were missing as well as her purse and cell phone.
2. What did she purchase at the Safeway store.
3. Did PF expect her to have Thanksgiving with him or his family?
It is possible LE has asked PF NOT to talk to the media and to keep what he knows to himself while they investigate. It is possible KB baked the rolls, grabbed her purse, and went for a quick walk (not unlike Mollie Tibbits). It is also possible PF texted her several times (and LE knows it), but he has been asked to not reveal ANYTHING to the media. LE may not discourage all "hype" regarding PF as it deflects from their "real" investigation into what has happened to KB.
The fact that she purchased a small home on her own earlier in the year (just big enough for her and baby?) may speak volumes about her feelings toward PF. She might not want to be in a married relationship with him. When I look at the photo of her and PF with baby, I sense a "standoffish" stance in her. JMO. If she did not want a romantic/marital relationship with PF, she may have met someone she was interested in through work, etc. She was exposed to a "lot" of eligible men in her line of work, and she is a very attractive woman. Being a flight instructor, it sounds like most of her clients would be "temporary" to the area.
We know so little about her (unlike SW), that it is hard to try to understand what her habits, likes or dislikes truly are.
This is the most puzzling disappearance case I've come across in a while. The "only" reason we are questioning PF is because of his reluctance to talk to media, etc., when it may be that he has been asked NOT to talk to media as the investigation progresses. He may be the one person LE has actually cleared in her disappearance.
Just throwing some ideas out there for chewing purposes.
Praying she is found soon.
