With the prosecution failing to prove their case beyond a reasonable doubt, the jury in the Casey Anthony presented the most controversial "Not guilty" verdict since O.J. Simpson's trial.

On 'Primetime Nightline: Casey Anthony: Not Guilty' (Wed., 10PM ET on ABC), they had one of the jurors, Jennifer Ford, in the trial on to talk about the verdict, and her feelings about the case.

When asked why they declared Anthony not guilty, she stated, "There wasn't enough evidence. If you're going to charge someone with murder, don't you have to know how they killed someone, or why ... where/when/why/how? Those are important questions that were not answered."

But a verdict in a court of law on very specific charges is one thing. When asked if she thought Anthony might have killed her daughter, Ford replied, "I feel like she had something to do with it." But she wouldn't speculate further.
