On June 21, Bradley discovered that a flaw in his software misread the forensic data and that the word "chloroform" had been searched for only one time and the website in question offered information on the use of chloroform in the 19th century.[62][63] On June 23, Baez called Cindy Anthony to the stand, who told jurors she had been the one who performed the "chloroform" search on the family computer in March 2008. The prosecution alleged that only Casey could have conducted this search and the others because she was the only one home at the time. When asked by prosecutors how she could have made the Internet searches when employment records show she was at work, Cindy Anthony said despite what her work time sheet indicates, she was at home during these time periods because she left from work early during the days in question.[86] Bradley alerted prosecutor Linda Burdick and Sgt. Kevin Stenger of the Sheriff's Office the weekend of June 25 about the discrepancy in his software, and volunteered to fly to Orlando at his own expense to show them.[62][63] On the same day, the judge temporarily halted proceedings when the defense filed a motion to determine if Anthony was competent to proceed with trial.
