Another day, still no answers. I am starting to form scenarios in my head that are not the outcome everyone is hoping for. FWIW, my current scenarios are:
1. A car with several young adults and possibly teens come in contact with Mollie somewhere along her way. Maybe she knows them, maybe not well, but she likes youth and would not be alarmed by them. Somehow she winds up going with them. On a long drive. Or to the home of one of them. Possibly they are not nice people. Mollie is very nice. She continues to be nice, and bullying begins for no good reason(because bullying never has one). Someone takes her belongings, maybe takes a picture of Mollie with her phone and sends it. Somehow things go off the rails and there is an altercation. Worst case scenarios from this point on. If this is what happened, this is why certain people would not come forward, and that could go on until someone breaks.
2. An acquaintance, who has always had a thing for her. Maybe even still held hope she would go out with them. Now that she is going to a huge family wedding and possibly getting engaged, this person turns desperate because time is running out. Somehow lures Mollie away, she rejects the whole idea(probably firmly but nicely) and is not allowed to leave, or a worst case scenario happens, or she is still being kept somewhere.
3. Last but not least, Mollie is betrayed by someone she knows very well, some kind of argument/fight happens, and worst case scenario happens, complete with hiding of evidence of all sorts.
I am about 80% sure it is not a stranger abduction, I could entertain the idea of a local SK who just happened to see her and choose her, because those guys are everywhere. If all of the above are wrong, someone accidentally ran into her with a vehicle and got rid of all of the evidence.
Sad to say, I am hoping for the "she is being kept somewhere" idea. Because clearly she did not leave on her own. And someone keeping her somewhere is the only scenario where she is still in this realm.
So if anyone from any of these scenarios is here, reading this, at least call, give a tip, or some clue of what happened so this family can get some closure. There's not any real reason not to at least do that, whether you are a caring person, a scared person, or cold hearted lunatic. Just get it out there.
