Johnnie Cochran conducted an extensive cross-examination of Detective Tom Lange focused on crime-scene procedures, evidence collection, and chain of custody. Lange testified that the victims' hands were not bagged, that it was his information blood spots on Nicole Brown Simpson's back were not collected or examined at the coroner's office, and that several items were booked late or never booked. Cochran also questioned the nearly three-week delay in collecting rear-gate blood, the lack of a maintained police perimeter at Bundy during that period, and Lange's taking Simpson's Reebok shoes home overnight before booking them. The defense used these points to argue investigative failures, while the court sustained a hearsay objection to Lange testifying about fingerprint comparison results and deferred ruling on a disputed crime-scene videotape.
