Michael Norris, a Network Courier employee based at Los Angeles Airport, was called as a defense witness and examined by Robert Shapiro on July 12, 1995. His testimony drew cross-examination from Marcia Clark and a further round of redirect and recross, suggesting the prosecution saw something worth challenging in what he had to say. Norris appeared on the same day the defense presented Robert Heidstra, whose testimony about events near the crime scene dominated the proceedings.
