Defense attorney Jose Baez says Casey Anthony did not murder her daughter Caylee, but that she accidentally died in a swimming pool on June 16th, 2008 and the situation snowballed into a coverup. Baez made those claims in the opening statements today during the trial in Orlando. Prosecutors said in their opening statement that two-year old Caylee died from duct tape that had been placed over her mouth and nose. The 25-year-old Anthony is charged with first-degree murder. If convicted, she could be sentenced to death.
