Defense attorney Peter Neufeld conducted cross-examination of prosecution DNA expert Dr. Bruce Weir, eliciting omitted genotype pairings for Bronco items 303–305 and glove G10. Weir agreed the Bronco omissions appeared biased against Simpson, while his item-31 answer remained conditional on an uncertain-allele hypothetical. Neufeld systematically challenged Weir's methodology, attacked his credibility regarding the National Research Council's DNA statistics report, and established that Weir had been excluded from the second NRC committee because he was perceived as a 'partisan.' In the afternoon, the court heard motions on expert report discovery, subpoenas related to Mark Fuhrman's alleged racial slur admissions, and release of sealed juror dismissal transcripts.

• Weir acknowledged omitted genotype pairs for Bronco items 303–305 and glove G10; his item-31 answer depended on a hypothetical uncertain allele
• Neufeld questioned different treatment of possible alleles across items; Weir acknowledged specific omitted pairings while distinguishing item 31's definite reported call
• Neufeld established Weir's opposition to the NRC methodology and that Weir was excluded from a second NRC committee for perceived partisanship
• Judge sanctioned Neufeld $250 for speaking too loudly at sidebar during a contentious evidentiary dispute
• Court denied motion to quash subpoenas to DA personnel regarding Fuhrman's alleged admission to racial slurs, ordered in camera questioning
• Court ordered release of sealed juror dismissal transcripts by July 3rd, with personal identifying information redacted
