It wouldn't surprise me if someone that could do what she did could have killed them. I was wondering though, if the oldest might have run away with them and they got trapped hiding and suffocated .
That would be even sadder, if possible.
No, I think Tiffany finally finished confessing. How else would the cops know where to look for the children's bodies?
Certainly a possibility until proven different. Suffocation was a thought I'd had too.
