Casey Anthony was acquitted of killing her daughter six years ago, but now the judge who presided over the case thinks the Florida mom may have killed her 2 year old daughter by accident.
Former circuit judge Belvin Perry Jr. doesn't believe any of the theories presented in court -- like an overdose of Xanax or a drowning in the family pool. But he does think it was accidental.
"Based upon the evidence, the most logical thing that happened was that she tried to knock her daughter out by the use of chloroform and gave her too much chloroform which caused her daughter to die. Chloroform was used as anesthesia back in the day before there was real anesthesia to render someone unconscious. I don't think she ever anticipated the result. The only person that actually knows what happened is Casey Anthony," Perry said.
The judge says computer searches for chloroform and the volume of the chemical found in Casey's trunk convinced him. But he admits this is only a theory.
