The day was dominated by extended examination of Detectives Tom Lange and Philip Vannatter, with Robert Baker methodically attacking the LAPD's evidence handling procedures through multiple rounds of cross-examination and redirect cycles. Lange faced detailed challenges on time gaps between evidence collection and booking, contamination from a blanket placed on the victim's body, and the placement of the knit cap at the crime scene. Vannatter was then called to establish chain of custody for Simpson's blood reference vial, but Baker immediately exploited an unwitnessed hour-and-a-half window when the vial sat on Vannatter's desk at Parker Center, while also establishing Vannatter's potential bias through his friendship with the Goldmans and ongoing book deal negotiations.

• Detective Lange cross-examined on ten-week gap between retrieving pendant and keys from Simpson's duffel bag and their formal documentation and booking.
• Baker challenges the position of the knit cap found at the crime scene, arguing it contradicts Lange's explanation that it was kicked under the gate.
• Lange acknowledges leaving the crime scene uncovered for two hours and failing to preserve a blanket placed on the victim's body as evidence.
• Revelation that Detective Vannatter had access to Simpson's travel bag on June 13, four days before it was formally confiscated on June 17.
• Detective Vannatter testifies he personally transported Simpson's blood reference vial but an hour-and-a-half window of unwitnessed handling sits at Parker Center.
• Baker establishes that Vannatter considered the Goldmans friends, had multiple meetings with plaintiffs' attorneys, and was actively negotiating a book deal.
