Detective testimony dominated Day 4 as the prosecution walked through the early morning investigation at Simpson's Rockingham property. The defense methodically attacked the procedural integrity of the detectives' decisions, questioning whether observations justified warrantless entry or if celebrity status drove the investigation. Key disputes centered on the glove discovery timeline, blood evidence location, and whether detectives had genuine emergency justification to enter the property.

• Detective Fuhrman's cross-examination revealed significant gaps in his investigation notes and timeline inconsistencies
• Lead Detective Vannatter testified about observing the Bronco, blood on the door handle, and information from Kato Kaelin about thumping noises that justified entering the property
• Defense attorney Shapiro attacked whether the four detectives' decision to enter Rockingham without a warrant was truly justified by emergency circumstances or driven by Simpson's celebrity status
• Prosecution clarified Fuhrman's emotional reaction upon discovering the Rockingham glove that matched the Bundy crime scene
• Defense highlighted omissions in official reports, including missing references to alleged observations of a shovel and plastic in the Bronco
