The defense recalled Detective Vannatter and presented Larry and Craig Fiato and FBI Agent Michael Wacks to challenge Vannatter's testimony that Simpson was not a suspect when detectives went to Rockingham. Larry Fiato testified that Vannatter said Simpson was a suspect; Craig Fiato described only a general remark that 'the husband is always the suspect'; and Wacks said he heard a suspect-related remark but did not hear Simpson's name or Rockingham and could not recall the exact words. Vannatter denied making the statement and maintained that Simpson became a suspect only after the glove discovery. The court granted a protective order for the Fiato witnesses, and the defense argued to recall FBI Agent Martz and call Dr. Frederic Whitehurst to challenge Martz's EDTA methodology and alleged pro-prosecution bias.

• Judge Ito grants defense motion to recall Detective Vannatter for impeachment based on Fiato statements
• FBI Agent Michael Wacks testifies he overheard Vannatter say words to the effect that they went to a house because a man was a suspect, while acknowledging he did not hear Simpson's name or Rockingham and could not recall the exact words
• Larry Fiato testifies Vannatter said Simpson was a suspect in two separate conversations (hotel and courthouse)
• Craig Fiato hedges his prior statements, characterizing Vannatter's remark as general rather than Simpson-specific
• Court grants protective order excluding cameras and sketch artists during Fiato testimony (FBI-protected organized crime informants)
• Court hears arguments on the defense request to recall FBI Agent Martz and call Dr. Frederic Whitehurst regarding EDTA methodology, record-keeping, and alleged pro-prosecution bias
