Hi Bluedevil,
Excellent thoughts in your post.
I've thought similar but then here's my take:
The real Dad is someone Casey named (most likely to get her parents off her back and have them stop asking her questions she couldn't answer). And we all know how realiable Casey's stories are, huh? lol
I'm thinking LE needs to know the 'true' father because if the deceased father isn't bio dad, then there could, COULD be someone else out there who could have Caylee....as in, the real bio dad.
I mean, it's a longshot, I know but I would think LE would want to cover all their bases (CYA).
If, Big IF the deceased is not the bio dad, maybe whoever is could have Caylee?
About getting inside the head. True what you typed. Very True.
But another thought....
If precious Caylee is found and there is too much decomp and manner of death becomes 'undetermined' then Casey could reach inside her head's bag o' tricks and pull out the "it was an accident!" card.
How would anyone really know?
Would we ever know?
Casey: She accidentally fell and hit her head and I panicked and.... blah, blah, blah..yadda yadda yadda!
In this case, the most, the MOST that could come out of the whole tragedy is Casey getting 2nd deg. manslaughter, no?
