I do think certain people behave in certain ways. A grieving parent would have to be a very specific kind of person to think about proving a cover story first, and grieving second.

It's not that I don't think anyone is capable of it, I just think the number that are capable of dealing with the death of their child like that is minuscule, and would put them at the socio/psycho path end of the spectrum.

Innocent until proven guilty, and no one has anything remotely resembling proof or evidence.
