Plaintiffs built their domestic violence motive case through Ney's testimony that a caller identifying herself only as Nicole reported stalking and a death threat, Fischman's account of Simpson's growing frustration with Nicole, and his unusually subdued demeanor on the day of the murders. Petee's timing study reported a fastest accelerated Bundy-to-Rockingham run of approximately four minutes and six seconds. Defense challenged witness credibility throughout, pointing to inconsistent documentation, destroyed notes, potential bias, and methodological concerns.

• Nancy Ney testified that a June 7 caller identifying herself only as 'Nicole' reported stalking and a death threat; defense challenged the identification, hearsay, and gaps between Ney's call sheet and courtroom account.
• 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 his fastest accelerated Bundy-to-Rockingham run took approximately 4 minutes 6 seconds; on cross-examination he said the routes were assigned by a law office or law firm and his handwritten notes had been destroyed.
• 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 testified that a fake goatee/disguise kit was regularly present on Simpson's desk through June 10 and that Simpson's dog Chachi was well-trained and never ran off the property.
• Defense moved to exclude Dr. Bruce Weir over allegedly undisclosed revised frequency statistics, including a change from 1-in-3,000 to 1-in-6-billion; the judge declined exclusion but ordered a pretestimony deposition and production of related materials.
