I too worry about the girl, but I now understand why they haven't found her. According to what I read, in her first call she made most of the allegations. Her second call started with allegations, but at the end she recanted.
Now she is possibly in with a group of other FLDS women who may or may not be giving their right names, may or may not be giving their right ages, and may or may not be giving the right names of their children and husbands.
They say when she made the call she spoke quietly because of fear of being overheard. So she may be taking her cues from the women around her. Will she finally admit? That will be a huge step for her. She called about herself, now all the children and most of the women have been removed.... she could very well be having second thoughts because she called about herself and she probably knows some women who believed and who wanted to stay but didn't because their children were taken.
But I too worry. If they find the girl, there will definately be charges. If they don't find the girl, will it put the raid, the other charges and etc in question? If they don't find the "fruit" will the whole tree collapse? If there is any question of that, then they could have possibly heard about her call and determined to make sure she could't be questioned.
