But he did take it, and it proved he was not the Father. Maybe he just wanted to be left the hell alone and resented the fact he was being looked at as a suspect or possibly being the Daddy of his sister's child.
A family that undergoes a murder/missing child cooperates at any length. I am not making that up. That is fact.
The first thing you want to do is exonerate yourself so the LE will concentrate and go after the RIGHT person.
Ego, hurt feelings, tiredness or lack of patience does NOT take precedence when the main objective is to move the investigation on.
This family did everything to thwart the investigation.
Casey learned her deception from the best it's starting to look like!
So **** Lee with that excuse (which, is not correct anyway IMO) He didn't have the luxury to insert his personal problems in this matter.
But like I just said, doesn't matter anyway because that is not why he refused. He refused because he thought it might come back positive.
Caylee = Casey + Lee
