kcsmom talked to a neighbor at their last residence and was told Zahra was alive and seen when the moved out- so she DID make it to the new house. (but i won't speculate on how long she was or wasn't there)
there are just some things that don't connect- if they did find actual evidence of a body where they are searching wouldn't they have set up "the little blue tent" and have a coroner on scene by now? And if AB led them to the sight and confessed why is he not in custody and why is he even still on scene?
They should have. If they had an actual hit by an HRD dog. If they were following protocol.
And as for the other question....I have no idea. That should not be the case at all.
