At 11 can you imagine what she was thinking. I'm no expert with the mind, but I can imagine that one's ability to really mess with her is paramount at that age. Then after repeatedly raping her, I can't imagine what was going through her mind. Sure she's old enough to remember, but something so graphic and violent could surely alter normal thinking. On top of that, at 11, being abducted you aren't as willing to try to escape, the mind games being played by the abductors could have created this image that they were the good people and she doesn't want to leave them, etc. After so many years that's what she believed... I've never been in a traumatic experience so I can't even begin to know what happens to the mind, but I'm sure that there is an explanation for her not escaping sooner or feeling that living in a shed, indeed was normal life. She's got two kids, 11 and 15 who have never been to a doctor or went to school. Imagine what is happening in their minds. This is a happy ending, but the beginning of a long road of therapy and recovery.
