Judge believes Casey Anthony killed daughter Caylee

ORLANDO, Fla. -- The judge in one of the highest profile trials in recent history has made a shocking admission.

Judge Belvin Perry presided over the Casey Anthony murder trial six years ago. Anthony was found not guilty in the death of her two-year-old daughter Caylee.

But Perry, who is now retired, told Orlando TV station WFTV that he thinks she did kill her daughter.

"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," Perry said. "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," he said. "The only person that actually knows what happened is Casey Anthony."

Perry said that computer searches for chloroform and the volume of the chemical found in Casey's trunk convinced him, but he admitted his thoughts are only a theory.
