Plaintiff attorney Peter Gelblum conducted a devastating, hours-long cross-examination of defense photo expert Robert Groden, systematically exposing resume inflation, lack of credentials, tabloid dealings, and methodological failures—ultimately showing that alleged photographic anomalies appeared across multiple frames. The defense then pivoted to toxicologist Dr. Rieders's EDTA testimony supporting the blood-planting theory. The day descended into procedural chaos with unauthorized wireless microphones, court exhibits left in a witness's briefcase, and a spectator showing jurors a graphic image, before the trial recessed for two weeks.

• Peter Gelblum exposed Robert Groden as lacking formal photo analysis credentials, having been paid only twice to authenticate photographs, and having inflated his resume throughout his career.
• Gelblum demonstrated that the 'anomalous' blue lines Groden claimed proved forgery in the Simpson shoe photograph actually appeared on multiple frames from the same photographic roll.
• Groden admitted under cross-examination that he was 'not sure' the Bruno Magli shoe photograph negatives were fake, retreating from his initial opinion.
• Courtroom discovery that Groden had left the courtroom with court exhibits in his briefcase, prompting Judge Fujisaki to rebuke counsel for lack of organization.
• In-chambers hearing revealed defense attorney Robert Blasier's wife and a Fox Television producer attempted to bring unauthorized wireless microphones into the courtroom.
• A courtroom spectator held up a composite graphic image depicting Simpson slitting Nicole's throat in front of two elderly jurors, raising serious security concerns.
• Defense toxicologist Dr. Frederic Rieders testified that EDTA detected in blood stains from Simpson's sock and the back gate indicates blood from purple-top collection tubes, supporting the defense's blood-planting theory.
• Judge Fujisaki adjourned the trial for a two-week holiday recess and issued strict jury admonitions against media exposure and discussion of the case.
