In the first day of testimony for the defense, O.J. Simpson's daughter from his first marriage describeda very different O.J.than the man prosecutors say brutally murdered his estranged wife and Ronald Goldman. Arnelle Simpson said that she had never seen her father so upset as when he learned that Nicole Brown Simpson had been killed. As part of thedefense strategyto show the former football star as a genial, loving man who could never have committed such a crime, Arnelle said her father and mother in law had had genial relations after their separation. Casting doubts on prosecution evidence that linked O.J. to the crime because of evidence that his hairs were found on Nicole's clothing, Arnelle testified that he often spent the night at her house even after the two split up.
