Taking a fresh perspective on this.
Some things ARE speculation, like what her complete intent was - did she intend to run away for just a week, or for the rest of her life. What isn't speculation is whether she cleaned out her room - she did or she didn't, it's one or the other and her family and the police know which answer is correct. Yes or no. There's no speculation to it.
except for had she packed her belongings, or not unpacked them from Christmas Break. She had only been back a couple of weeks, both of those weekends were extremely busy for her. If it were me, I would just take things out as I was using them until I had time to completely unpack. Her boyfriends mom stated that often times she just unpacked as she needed things. If she took with her what was unpacked, what exactly had she packed? Those closest to her have stated that it didn't look packed to them.
Looking at this, it seems more and more certain that she intended to leave forever, but that's only my perspective.
That's the problem with so many speculating and stating it as truth if they don't know her habits. I am not saying that to be mean, but it is just fact.
What is more important than what her intent was - whether it was to leave for just a week and then suddenly come back, or whether it was to start a new life elsewhere, is did she meet with foul play in that first couple days? Did she survive beyond the couple days after she wrecked the car into the snowbank and left with just a few things in a backpack?
That seems like that's the focus that everyone needs to be looking at, and put aside the different ways we view her intent.
I know several on the board believe an adult should have no responsibility to at least let their family know that they're leaving for good and don't ever want to be contacted again, but I don't feel that way. In the case of severe abuse, where the parents can be charged with a crime and imprisoned for their treatment of a family member, then okay. You can leave and don't say bye.
There is no abuse. There is no controlling factor coming from any of them.
Otherwise, if you just leave and never let anyone know where you went, they waste their whole lives searching for you. That's just a stupid, unfair and cruel waste.
