Plaintiffs built their domestic violence motive case through testimony about Nicole's expressed fear of stalking and death threats, Simpson's escalating frustration with Nicole, and his unusually subdued demeanor on the day of the murders. A critical timing study demonstrated the crime scene could be reached from Simpson's home in under four minutes. Defense aggressively attacked witness credibility throughout, exposing inconsistent notes, destroyed evidence, potential bias, and methodological flaws that undermined plaintiff testimony.

• Nancy Ney testified about Nicole's June 7 call expressing stalking fear and death threats despite defense challenges on hearsay and note discrepancies.
• Dr. Ronald Fischman testified Simpson showed escalating frustration with Nicole and unusual subdued behavior at June 12 recital, subject to repeated impeachment.
• Private investigator Randall Petee testified a Bundy-to-Rockingham route took 4 minutes 6 seconds at accelerated speeds; defense revealed he destroyed his notes and the exercise was lawyer-scripted.
• Barbieri videotape deposition played; court struck Simpson's statement 'I didn't do it' as self-serving hearsay.
• Leslie Gardner testified black sweat suit left at Simpson's Rockingham home after May 25-27 video shoot; defense attacked her attorney's potential Brown family connections.
• Josephine Guarin confirmed disguise kit present on Simpson's desk through June 10 and dogs never left property.
• Judge ordered Dr. Bruce Weir's deposition before DNA testimony after plaintiffs failed to disclose revised frequency statistics (including 1-in-6-billion figure).
