I don't think the question is whether or not it takes the focus off finding Haleigh, because if it were discovered to be true that she was being abused, then
that could be a clue to finding out what happened to her.
It's also important to make sure Jr is safe.
I think the real question is only how convincing the evidence is. We can analyze and speculate, but really can't know for sure, since we haven't heard it all.
On the other hand, despite my insatiable curiosity for any information at all, like you, I wish it weren't so publicly done. :sheesh:
(I still can't help but scoff at paternal side gripes about the maternal side taking focus off Haleigh after the paternal side's ugly sideshow of a wedding and honeymoon.
