The defense mounted a significant forensic challenge through Dr. Michael Baden's testimony on blood evidence and wound patterns, but faced withering cross-examination that exposed inconsistencies and undermined his two-assailant theory. The defense also presented alibi witness Michael Gladden (placing Simpson at LAX at 11pm) and eyewitness Thomas Tallarino (claiming to see a suspicious person near the crime scene), but Tallarino's credibility crumbled under cross-examination over location discrepancies. A jury member was removed during the lunch recess, and fingerprint evidence showed no matches to Simpson among 17 recovered prints.

• Dr. Michael Baden extensively cross-examined on blood evidence inconsistencies, prior television statements, and inability to independently support two-assailant theory
• Jury member removed during lunch recess without explanation
• Alibi witness Michael Gladden testified he observed Simpson arriving at LAX around 11pm on night of murders
• Eyewitness Thomas Tallarino's testimony about seeing a suspicious person near crime scene systematically dismantled through multiple cross-examinations over location errors
• Fingerprint examiner testified 17 latent prints recovered from scene with none matching O.J. Simpson
• Defense attempts to establish alternative perpetrator narrative largely neutralized by geographic irrelevance of Tallarino's observation
