there s no possible way he could do this on purpose. and i m natalie morales. and this is dateline. she was crying and crying. i said, what s wrong? and she says, that he s dead. we all wanted to believe that it was an accident. a dark house, a husband with a gun. a wife dead on the floor. make sure that she is still breathing. oh, i don t think she is, damn it. there was no question who killed her. the mystery was why. i hear the door squeaking. and i hear a grumbling. and i hear the dog rolling. how could you not tell that s your wife? it was dark. i did he just kept seeing it was an accident and he didn t do anything wrong. others disagreed. we never for a second believed that he didn t know who that was that he was threatening. was it a tragic mistake? he was broken. or cold-blooded murder? he has fits of emotion, they re only down in front of the detective. a room too dark to see. turn the light off. or a story too hard to believe?
