The defense called eight witnesses, including several who challenged the prosecution's murder timeline by reporting that they were near or passed the murder scene between roughly 10:15 and 10:30 PM and noticed no blood, disturbance, or barking dogs during their respective observations. Prosecutors challenged the timing, observational basis, and defense contacts of several witnesses, while the defense highlighted that the prosecution had not subpoenaed Robert Heidstra, who testified that he heard male voices and a gate slamming around 10:40 PM.

• Shirley Baker testifies OJ was devastated and crying after learning Nicole had been murdered, and says Ron Shipp did not speak privately with him that night.
• Jack McKay describes OJ as friendly and jovial on June 8th, but Marcia Clark attacks his credibility based on one brief encounter and potential financial bias.
• Danny Mandel and Ellen Aaronson place themselves walking past 875 South Bundy around 10:25-10:30 PM, seeing and hearing nothing unusual.
• Francesca Harman testifies she drove past the crime scene at 10:20 PM and heard no barking dogs, directly contradicting prosecution's timeline evidence.
• Denise Pilnak places herself outside on her porch from 10:21-10:25 PM describing Bundy as 'exceptionally quiet,' hearing no dogs barking until 10:33-10:35 PM.
• Clark challenges the credibility of Mandel, Aaronson, Pilnak, and Telander by questioning their discussions with one another, contacts with defense counsel, and pretrial route or account review.
• Robert Heidstra testifies he heard male voices including 'Hey, hey, hey' and a metal gate slamming around 10:40 PM—the prosecution never subpoenaed him.
• The dog-barking timeline becomes a key battleground: Fenjves' preliminary-hearing account placed wailing at 10:15 PM, several defense witnesses reported no barking during their own observations, and Pilnak said she first heard barking around 10:33-10:35 PM.
