The trial featured testimony from Bloomingdale's shoe salesman Sam Poser regarding Simpson's shoe purchases, though no receipt proved he bought the specific Bruno Magli Lorenzo boots. DNA expert Gary Sims presented evidence from the Bronco and rear gate—including a highly anomalous rear gate blood sample with 270 times more DNA concentration than other crime scene blood and no bacterial degradation. The defense exploited these anomalies in cross-examination to advance their planted-evidence theory.

• Sam Poser testified that Simpson purchased shoes from Bloomingdale's multiple times but no receipt linked him to the specific Bruno Magli Lorenzo boot.
• F. Lee Bailey's cross-examination emphasized the absence of sales records and Poser's failure to recall selling Simpson the Lorenzo style.
• DNA expert Gary Sims presented results from Bronco blood stains and the rear gate stain (item 117), all matching Simpson's profile with frequencies of 1 in 57-150 billion.
• The rear gate blood sample showed extraordinarily high DNA concentration with no bacterial degradation despite presumed environmental exposure—a centerpiece of the defense's contamination theory.
• Barry Scheck's cross-examination of Sims highlighted DNA anomalies and the possibility of evidence planting.
• Judge Ito accommodated a juror's family graduation with early adjournment at 3 p.m.
