Shapiro conducted a cross-examination of Detective Vannatter, challenging deficiencies in evidence handling, documentation, and the accuracy of his search warrant affidavit. Key problems emerged including the Rockingham glove appearing in no detective's notes, an unrefrigerated blood sample held during an approximately two-hour custody interval that included time on an office desk and about an hour or more of driving, and Shapiro's disputed reading of June 29 handwritten notes to support his theory that the socks lacked blood on June 13. Darden addressed the defense challenges on redirect, and the day ended with Kato Kaelin beginning his testimony.

• Vannatter cross-examination reveals Rockingham glove appears in none of four detectives' notes or chronological records
• Blood sample handling exposed: unrefrigerated, transported on car seat for nearly two hours without documentation
• Defense challenges socks evidence, arguing handwritten notes showed no blood was found on June 13th and that blood was detected only through phenol testing weeks later
• Search warrant affidavit confirmed to contain two false or premature statements under oath by Vannatter
• Shapiro's dramatic moment showing his own bruised hand to establish injury context, prompting judge agreement it was 'absurd'
• Crime scene documentation questioned: photographs showed a bed strap in different positions, and Vannatter did not know why it had been moved
• Detective Lange recalled to confirm both south-side Rockingham doors were locked on June 13th morning
• Kato Kaelin begins direct examination, establishing his relationship with Simpson and Nicole Brown Simpson
