Here's a
list of articles about the case. The court overturned the convictions and ordered a new trial. This was based on the idiotic argument that the form for the jury was unclear about the option for a life sentence. So, the jury is thought to be smart enough to pass judgment on a life sentence, but too stupid to read a form. Since a new trial was ordered, and the moron wrote a letter to the prosecutor that provided a written confession that reinstated the capital murder charge, it's not double jeopardy.
