The fourth day centered on whether police lawfully entered O.J. Simpson’s Rockingham estate without a warrant and whether the glove, Bronco blood, and driveway stains should be suppressed. Detectives Mark Fuhrman and Philip Vannatter faced pointed questioning about uncertain timelines, delayed reporting, incomplete records, scene security, and the officers’ claimed fear that someone inside might be injured. Testimony from Kato Kaelin, Arnelle Simpson, Cathy Randa, and criminalist Dennis Fung reconstructed the early-morning events and clarified that presumptive blood tests were suggestive but not conclusive. After tense closing arguments portraying the entry as either an emergency response or an evidence hunt, Judge Kennedy-Powell deferred her ruling until the next morning.

• Mark Fuhrman acknowledged that his timing estimates were imprecise and that roughly 30 minutes passed before he informed lead detective Philip Vannatter about the Rockingham glove.
• Vannatter defended the warrantless entry as an emergency response prompted by apparent blood on the Bronco and concern that someone inside the estate might be injured.
• Kato Kaelin and Arnelle Simpson testified about the officers’ early-morning entry, their own interactions with police, and the absence of express consent to search.
• Criminalist Dennis Fung said presumptive tests indicated blood on the Bronco, driveway, and glove, while conceding that those tests were not conclusive.
• After extensive constitutional arguments, Judge Kennedy-Powell took the defense motion to suppress under submission for a ruling the next morning.
