witness from either side had seen brad physically violent toward nancy. for the $300 a week allowance there was a reason, the defense argued. remember the couple had serious debt. the defense offered contrasting scenes of the cooper marriage from another set of friends. >> people who had known the couple for years, did not jump on this bandwagon to paint this as an abusive relationship. >> reporter: remember that "i hate brad" day, the day the prosecution said the marriage hit its boiling point. on that very day, said laura hiller, nancy was making plans for saturday night, the day she disappeared. >> she wanted my husband and i to come over and play sequence with her and brad. >> was that a game you had played with the coopers before is this. >> nancy introduced us to that game. >> reporter: when nancy's friend jessica testified they had plans to paint her house at 8:00 saturday morning she had to be have been mistaken, said the defense, because nancy knew brad had a tennis game at 9:00 a.m. with mike hiller. >> i specifically sought out nancy to make sure it was okay with her.
