The day opened with intense scrutiny of Detective Luper's handling of Rockingham evidence, particularly a glove improperly handled before arrival of supervisors and Marcia Clark's completely undocumented visit to the crime scene. After Clark provided her account as an officer of the court, the trial transitioned to the DNA evidence phase with LAPD criminalist Dennis Fung beginning extensive direct testimony on blood and biological evidence collection procedures. Throughout, the defense mounted systematic challenges to evidence documentation, chain of custody, and exhibit admissibility.

• Detective Luper revealed he found a glove in Rockingham's master bedroom dresser drawer and held it in his hand, setting it on a table—all captured on video—before supervisors arrived to assess it
• Defense established that Marcia Clark's June 13 visit to Rockingham was completely undocumented: no log entry, no sign-in, no contemporaneous record, with Clark personally walking through the scene with Luper
• Detective Harper's recollection of when Clark visited Rockingham (June 13 vs. June 28) was undermined through crime scene logs, suggesting witness confusion between the two search warrant executions
• Marcia Clark provided a statement as officer of the court (rather than sworn testimony) confirming she left before the videographer arrived and had no prior knowledge of the tape
• LAPD criminalist Dennis Fung began systematic direct testimony documenting blood and biological evidence collection at both crime scenes with detailed chain of custody procedures
• Defense objected to exhibit boards showing phenolphthalein drain tests and serology results, challenging whether proper testing and preservation protocols were followed; Judge deferred ruling
