This is my first post here on WS and I appreciate all that you are doing here for the missing, especially children.
I try to put myself in Hailey's place, but that would have been over 30 years ago for me. When I was her age my Mother gave me a Raggedy Anne and Andy doll set for my birthday, which I thought was beneath me. I was in such a big hurry to grow up and unfortunately I did.
I don't know if Hailey was in a big rush to grow up in the way that I was, but it is possible. She seems to be by all accounts a responsible and smart little girl.
And she is just a little girl, but she may not see herself as one any more than I did at her age.
I don't believe she left on her own accord. I do believe someone totally unrelated to her daily life may have taken the opportunity to steal her from her loved ones.
Although statistics usually point to the family members in cases like this, it is still possible that none of them are involved. I really don't know how she would have looked at her Mother's boyfriend...whether with love or apprehension. If what her Grandmother(?) is reported to have said is true, then it would have been the latter.
If Hailey were to call her Mom's phone it would still be a major breakthrough. Since all available info indicates it is in possession of LE, they would have a good chance of locating her.
Praying for Hailey and everyone who is lost that they may be found.
