New data suggests that data in the Casey Anthony case may have been inaccurate.  What may seem like a trivial difference could prove to be vital to the case.

The finding of 84 visits was used repeatedly during the trial to suggest that Ms. Anthony had planned to murder her 2-year-old daughter, Caylee, who was found dead in 2008. Ms. Anthony, who could have faced the death penalty, was acquitted of the killing on July 5.

According to Mr. Bradley, chief software developer of CacheBack, used by the police to verify the computer searches, the term “chloroform” was searched once through Google. The Google search then led to a Web site, sci-spot.com, that was visited only once, Mr. Bradley added. The Web site offered information on the use of chloroform in the 1800s.
