Are we sure of her birth time/rising sign?
I was watching her story on CNN yesterday. They were discussing details of her trial and her "web of lies." She does seem like a compulsive liar, and she does it with such ease and conviction. Either she has a serious mental problem where she actually believes her own lies, or she is a sociopath.
For some reason, she reminded me a little bit of Diane Downs, the child killer from the 80s. The man she wanted to be with didn't want to be with her because she had 3 children, so she put them all in the backseat and staged a carjacking/shooting, and actually shot all three of her children herself. However, one of her kids survived and was able to tell the court that her own mother shot her. Diane's motive to kill her own children was completely selfish and she showed basically no remorse whatsoever. Similarly, it is said that Casey Anthony didn't report her daughter as missing for an entire month, and that she was partying while her daughter was missing. She was also a compulsive liar just like Diane Downs.
I looked up Diane's planets - she has a 5 planet stellium (all within 7-17 degrees) in Leo, and Pluto in Leo as well (26 degrees). She was diagnosed with antisocial personality disorder (sociopath) as well as extreme narcissism. it's possible that the narcissism part connects with the enormous Leo stellium/6 planets in Leo.

I feel like it's fairly obvious that Casey Anthony killed her child, since they found a strand of decomposing hair in the back of her trunk, and there was apparently a smell of a decomposing body in her car. People say she killed her daughter so that she could be more free and so that she could party and she didn't report her daughter missing for a month. While her daughter was missing, she was seen partying.
I think she could have a Leo ascendant. I also feel like Taurus could be a possibility, judging by her looks and personality. It's so hard to tell, but I think as the trial goes on, we'll learn more.
