The problem here is that Florida has a strange double jeopardy law. You can only try a person once on the incidence. If they try Casey on neglect and not murder, and they get a conviction on neglect, they cannot go back and charge her again for murder at a later time. Since she goes to trial in november on neglect in this case, LE has to bring the murder charges by then or that is all she can ever be charged and tried for. Several lawyers from Florida have commented on this.
For sure Casey will not face murder charges. Because of those screwy laws, Casey is winning big time. I'm afraid with what they have right now, I doubt a jury will convict. Reasonable doubt and all that. Heck the let OJ off. There are plenty people that believe that crazy kidnapping story.
The more she keeps her trap shut, she'll be doing just fine and get, what 6 years for child neglect?
