Rosa Lopez's conditional examination provided crucial alibi testimony, placing Simpson's white Bronco at his Rockingham home from 8:15 PM through the critical evening of June 12, 1994. Her account included audible evidence of Simpson's presence around 9:45 PM and 11:00 PM. The proceeding was consumed by procedural warfare after the defense's failure to disclose an earlier investigator's report to the prosecution, triggering sanctions and revealing a second alibi witness. Detective Fuhrman's morning encounter with Lopez revealed he had failed to document her statements despite asking to search the yard.
