only chance she will talk is if she if found guilty of 1st degree murder and faces death penalty- she may reveal Caylee's whereabouts for a reduction in penalty or a chance for parole. She will only do this before the penalty phase is complete- and than the prosecution probably won't deal. If I was a prosecutor I wouldn't deal unless CA and GA begged me to do so to find a body to bury. Families have done this in other cases. If TE finds Caylee- no deal.
