The defense called eight witnesses to systematically challenge the prosecution's murder timeline, with multiple individuals testifying they were near or passed the murder scene between 10:15 and 10:30 PM and observed nothing unusual—no blood, no disturbance, and critically, no barking dogs until much later. Marcia Clark aggressively cross-examined each witness on credibility and coordination with defense counsel, while the defense highlighted that the prosecution had never subpoenaed key witness Robert Heidstra, who heard male voices and a gate slamming around 10:40 PM.

• Shirley Baker testifies OJ was devastated and crying, directly contradicting Ron Shipp's claim of a private conversation about the murders.
• 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 reveals multiple defense witnesses (Mandel, Aaronson, Pilnak, Telander) extensively coordinated their accounts with each other and defense counsel before testifying.
• 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.
• Dog barking becomes key timeline battleground: prosecution's Pablo Fenjves claimed barking at 10:15 PM, but defense witnesses heard no dogs until 10:33-10:35 PM.
