To add to the above thought:
If she is being helped by someone, they may be afraid to come forward because they have been painted as some sort of monster. For all we know, the safest place she could be right now is wherever she is. All the talk about who took her or who is holding or coercing her may be having an negative effect. Abby could have sent the letter to let her mom know she was ok but she may be afraid to reveal herself not for the backlash she would face, but the lynch mob that will accost the good samaritan(s) helping her.
I will acknowledge that this is not a popular view but it needs to be said. I live in NH and I, unlike so many others, am not satisfied thinking that someone abducted her, especially since LE won't even say the words. People are so fearful of the bogeyman that they are willing to accept the fact that he is responsible when there is yet no evidence of that. But it is the only thing many want to talk about. We know the bogeyman exists, it's why we teach our children to act carefully, safely and take precautions, but until LE says that is the case here, I see it only as one of a few equally viable scenarios.
The fear of the unknown is the only real fear here and until she is found it is all unknown. She is not an adult and she is missing, that is the only problem.
