First comment on this case....
I agree it’s not human trafficking. Like, not at all. I live in a city with one of the largest human trafficking problems because we have the largest and busiest airport. My husband is a commercial pilot. We learn a lot from the news here about how to spot human trafficking. He is also highly trained on how to spot it on planes and in the airport. She does not fit the profile one bit. Not at all.
I know we are not allowed names or anything of that sort, but I have my theory, and it’s seeming to me it is definitely someone known to her. The whole left without contacts/glasses (my daughter does it all the time when in a hurry or lazy) sounds to me like she either left in a hurry or someone came in while she was asleep or knocked on the door after she had gotten into bed. She would be wearing the Fitbit to bed for sleep monitoring. The phone could have been grabbed by her or the perpetrator. If she were lured out, they probably knew she had it but took it from her. Who knows. But....I completely think this was done by someone she knew pretty well - maybe even a prank or someone just getting mad at her and it all goes wrong/a little too far. I’m totally not thinking a sex offender.
Side note: I didn’t have time to read through the entire thread. What does the father do? Does he make good money? Ransom worthy? I don’t think this was an abduction, though.
Another side note: has it been said that she ever wanted to move to a larger city (say San Francisco near dad) to work after college? What were her aspirations? Did she want to get out of the small town? She seemed pretty darn close to her father and seemed excited about her “new family”. Edited to add: someone might be mad about this idea of leaving Iowa.
