Someone mentioned that maybe they have a suspect, but the suspect has fled. If that were the case, I would think they would hold a press conference, asking the public for help finding the person -- even if they describe the person only as a "potential witness" who they'd like to talk with.
As for who did it? For now, I'm betting on it being someone on the outer edge of her circle. Maybe a store clerk who saw her a few times and maybe even chatted with her, or a classmate, a casual acquaintance. Someone she had incidental contact with -- the contact didn't mean much to her, at least not enough for her to mention it to her inner circle, but for the other person, it was mistakenly taken as something more.
I'm not buying into:
- Suicide
- Run off and start new life
- Secret boyfriend
- Pig farmer
I'm not ruling out abduction by stranger. I stand by my statement that such abductions of adults are extremely rare. But in this case, it's a possibility because there is so much that doesn't make sense. The level of FBI involvement also supports this.
We can assume, by the way, that if it happened at the house, this was not a robbery-gone-bad or a typical sexual assault or killing. If it were, why remove her (or her body)?
If it happened while jogging, that's a whole other story. She or her body could be anywhere.
