The defense mounted intensive technical attacks on DNA evidence and police procedures through witness and expert testimony. Detective Mulldorfer testified that no access log was kept for the Bronco, while cross-examination established that, aside from Meraz's theft, the vehicle was properly secured at Viertel's; Lieutenant Spangler testified about Fuhrman's movements at Bundy. DNA expert Dr. Gerdes launched a comprehensive assault on LAPD's contamination protocols, though opposing counsel systematically challenged key aspects of his theory during cross-examination.

• Detective Mulldorfer reveals no access log was kept for Bronco despite "special care" evidentiary hold status
• Lieutenant Spangler testifies Fuhrman was wearing a jacket at 2:30 AM but not at 3:00 AM, and gives new testimony about walking the north pathway at Bundy that was absent from his criminal trial testimony
• DNA expert Dr. Gerdes systematically attacks LAPD's contamination protocols and sample handling procedures as creating "unacceptable risk"
• Tom Lambert's cross-examination challenges Gerdes' contamination theory; Gerdes accepts all RFLP results except possibly item 52 and calls the nine-probe rear-gate match "very significant"
• Judge sustains most of the Henry Lee deposition objections reviewed—roughly 10% of the total—on relevance grounds; Baker agrees to edit videotape over weekend
