The Defense launched its case with Arnelle Simpson providing extensive testimony about the Rockingham household, the white Bronco's use, and June 13 morning when her father learned of Nicole's death. The Defense called four additional witnesses—Carmelita Simpson, Eunice Simpson, Carol Connors, and Mary Collins—to build narrative supporting emotional devastation, credibility attacks on Ron Shipp, and depict OJ as romantically invested with Paula Barbieri in the days before the murders. Multiple evidentiary battles unfolded over the admissibility of OJ's statements while watching news coverage and a handwritten letter from Nicole.
