Detective Tom Lange underwent a systematic cross-examination by Johnnie Cochran focused on gaps in police evidence handling—blood on a dog that was not tested, photographed, or documented; a glove moved before it was photographed with no report written; duplicate exhibit numbers; and chain-of-custody questions involving eyeglasses. In a separate courtroom-conduct dispute, Judge Ito cited Christopher Darden for contempt after repeated admonitions; Darden later apologized after reviewing the sidebar transcript, Ito accepted the apology, and Ito offered an apology for his own reaction. Across the day, the defense challenged the thoroughness of the investigation and its evidence documentation.
