So far, there is zero evidence that Haleigh has been raped and killed. Until there is, I for one, am holding onto hope that she is alive.
Secondly, now is not the time for her to be trash talking anyone. The time for that was when she went to court for custody. If Crystal did not like the outcome the first time, she could have refiled.
Thirdly, a seventeen year old CAN babysit at anytime of the day or night. Having a teen sitter is not against the law.
And finally, I can think of only one reason that she, as the mother of a missing child, would want to shift the focus off of Haleigh and onto the father...and that reason is that she herself is guilty of something.
All the above are my opinion.
