I think what she's saying is she doesn't necessarily agree or disagree with anything anyone is saying about Dan, but instead of bashing him on this website - simply pray that WHOMEVER is responsible for the girls murder be found, let the courts/LE see what is needed to be seen (again, that God lead them to the truth) and justice served via their sentence.
That's how I read it. I don't think she's giving any indication that she thinks Dan is responsible for their murder. JMO of course.
I think her main message is to hand it all over to God and let HIM be the judge and jury. Everyone else just needs to pray for justice and not judge.
I think you are absolutely right.
