I think that Casey, Lee, Cindy, and George know who the father is. I think that, as soon as Cindy found out that Casey was pregnant, that was the second question she asked. And I think the answer she got was a lie. Remember, Casey pinned the pregnancy on Jesse Grund, but he was wise enough to have the paternity test done (and I'm no fan of Jesse Grund, but he did that right). So at the point that Casey was caught in that lie, she was forced to tell her mother who the father was. At that point, Cindy took control (as usual).
I feel that the whole family was in collusion about the paternity, and they concocted a story, or stories, to cover the truth. They never thought circumstances would necessitate them re-evaluating the lies they'd told. But, with Caylee's death came comparisons of stories that each family member had told others, or even the media. Why they never got their story straight is probably attributable most of all to Anthony Arrogance. They thought they were smart enough to pass it off and never be questioned.
Somewhere in Florida--probably in Orlando--is a young guy who fathered a child with Casey Anthony. That young man deserves even now to know the truth. It is not up to Cindy Anthony to determine what is "best." It is not up to George Anthony to determine what is "best." The father should have been given the option to KNOW his daughter, to SUPPORT his daughter, to LOVE his daughter, and to MOURN his daughter.
The truth will come out and the father will know (if he hasn't already been told in the three years since Caylee's death). Most certainly. And when it does, that poor man will only be able to MOURN his daughter, never having had the chance to KNOW and LOVE her.
Why should the mother's family have the right to exclude a father from his child's life, when the father was never even informed that he had a daughter. He wasn't given a chance to support her, to love her, to care for her. He had those rights and responsibilities denied him by this selfish, conniving family. But a mistake in the past, even as huge as this one, doesn't merit cascading mistakes in the future. If the state knows who the father is--and I'm almost certain the state knows--then this man should receive that information. I would think it criminal for the state to do anything BUT inform this father of his deceased daughter's very existence.
