Here is where my mind s at tonight:
1. PC will be unnecessary, and something will break tomorrow.
2. There are only a few real scenarios, all of them are possible, and at different times I suspect them all.
To me it is probably either of these:
1. Someone she knew well, possibly a co-worker or fellow student had an unrequited crush on her and it went off the rails. This person lured her away easily and is keeping her in some fashion.
2.Someone she thought was someone else, ie: on SM, someone who pretended to be a peer, etc. Or in person, a person she knew on sight but who used a ruse of something familiar.
3. She had a flirtatious but non-meaningful online banter with someone who is IRL not stable, and they went and got her. Maybe she went to meet them, and it went off the rails from there.
None of these things point at her as the person responsible, because any of these would be due to someone manipulating a young nice person. Even people who seem like your BFF online or at school or what have you can have issues you never suspect. And as far as 2 and 3 up there, I am still thinking "mean girls". I hope whatever it is, she is alive and ok, and gets home safe. Even if someone is embarrassed or ashamed or frightened to come forward, this has really been torturous for a family, it's using up crazy amounts of resources, and it's just plain sad. So let's hope for the best.
