a backyard spa, police asked chris hall to explain what happened that morning. what chris did not though was that his neighbor had also talked to police, and she told a very different story than the one chris was telling. here again is keith morrison. >> chris and cristi hall's three daughters clung together in grief and shock, all through the dismal evening hours of that worst of all days, june 7, 2007. waiting for their father to return from the police station. and they wondered, why was it taking so long? then the phone rang. and they had their answer. >> you know, broken-up words, and he's crying, and we're crying. that was when he said they think i hurt mom. i mean, he was very upset.
