I am conflicted in my hypothesis now, I feel like the message from LE is that they believe she was taken, but I feel like the message from the family is that she left with someone (dad says come home, it will be okay, mom says just come home, etc). I agree with others whom have said the "getting to know Mollie" comment could elude to her being involved in something she hid from her everyday life (drugs perhaps?). But if that is the case, I still don't understand why the nationwide FBI search with major media coverage, as she is an adult after all, she would not be considered a runaway. I feel like the comment from the brother about joking that the boyfriend should propose to her at his wedding could have been the trigger for her to leave (maybe this was the topic of the 3hr convo with her dad), or if she was taken by some admirer whom felt she was with the wrong guy it could have been the trigger to take her to prevent the possible proposal. LE would not be so tight lipped about the timeline they are confident in if they didn't suspect foul play (as a previous poster said, they are probably trying to protect against a fake alibi). I also felt like the comment in the PC about "who was in Brooklyn that night" was giving away the fact that she either left with someone from out of town or was taken by someone from out of town. This is probably why they are not doing much searching locally.
