The defense mounted a coordinated attack on the investigation's foundation, recalling Detective Vannatter and using FBI informants Larry and Craig Fiato to testify that Vannatter told them Simpson was a suspect when police entered Rockingham—contradicting his trial testimony that Simpson wasn't a suspect until the glove discovery. FBI Agent Michael Wacks corroborated portions of this account. The court granted protective orders for the Fiato brothers and set the stage for the defense to introduce FBI whistleblower Dr. Frederic Whitehurst to impeach the prosecution's DNA testing procedures.

• Judge Ito grants defense motion to recall Detective Vannatter for impeachment based on Fiato statements
• FBI Agent Michael Wacks testifies he overheard Vannatter tell informant Larry Fiato that Simpson 'was the suspect' at Rockingham
• 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)
• Defense files motion to recall FBI Agent Martz and introduce whistleblower Dr. Frederic Whitehurst to challenge EDTA testing procedures and FBI lab bias
