OJ Simpson took the stand as an adverse witness and faced a devastating direct and cross-examination from plaintiff attorney Daniel Petrocelli spanning the entire day. The examination focused relentlessly on Simpson's domestic violence history with Nicole Brown Simpson—particularly the January 1989 incident—and his relationship dynamics through her death, with Petrocelli systematically catching Simpson in contradictions between his 1994 police statements and his current testimony. Multiple sidebars resulted in rulings favoring the plaintiff, including admissibility of Nicole's diary entries and Lenore Walker's expert notes, which the judge found relevant to state of mind and motive. By day's end, the plaintiff had methodically established a pattern of jealousy, control, and violence, alongside potential financial and romantic motives for the murders.
