Anthony-the only suspect?
Anthony was the last person with her daughter Caylee, and everybody including her admitted it.
She lied about every person, place, and times of that last time with her daughter.
Don't you think, like any other person she should have been a suspect and arrested for being a negilgent mother and lying of her where abouts right off the bat?
I think if she were arrested she would give it up knowing this would give her some specific set knowledge of how much time she would have left in jail being the self-centered person she is.
