Seems to me with Casey being Casey and manipulating people/events to her liking, Caylee's father may very well never have known he had a beautiful baby girl. Maybe he has seen the coverage but not come forward because he thought there was nothing to be gained other than unwanted publicity, and he thought her killer was going to be put away for a very long time, at a minimum.
Here's what I'm praying - that he, like so many people across the US and in other countries , is sickened and angered by this verdict. That he/anyone that thinks they may be Caylee's daddy come forward for a DNA test. Caylee's profile is already on file. That once he's shown to be the daddy, he sues Casey for wrongful death, parental alienation, and/or anything else that could possibly apply. I think she likely prevented him and Caylee from knowing each other. I can easily see it being a one night stand and him having to make it clear to Casey, that's all it was. She is bitter and when she finds out she's pregnant, she says screw him, and doesn't let him know. IMO perfectly possible given how she acts.
A la OJ, I hope Caylee's dad can make sure Casey never sees a dime of any profit from Caylee's death. I don't even care if it's just because he wants to cash in. I was thinking yesterday about how all of us felt so sickened and helpless about this travesty of justice. I was thinking, but what can we DO to make a difference. I wonder if we can put a bug in the media's ear to publicize a search for Caylee's dad. Or create a fund to help anyone who might be her dad to get a DNA test??? IDK. I just think he might be able to bring justice where the jury failed. (And yes, I believe they failed to use logic and reason, or to deliberate slowly through all that had been presented.)
