And Joni says that as the only other person actually in the house watching it all unfold, only she knows the true relationship between Mindy and Andy Barani.

He was a great father.

He was not a child abuser.

That is the issue here.

Right, and that is definitely not a true statement.

And a father desperately trying to save her.

She says he locked up the phones.

Yes, he did do that.

She was calling friends in Indianapolis and making arrangements to run away.
