evidence dave even left his house the night debbie was abducted and presumably murdered. his daughter insisted he could not have left the house without her having heard him. >> it doesn't seem at all possible. >> even though investigators would tell the court the kids slept so soundly it was hard to wake them up when they went to see them one morning, the defense claims that the prosecution's theory of what happened just didn't add up. >> that is just beyond belief that somebody would take that kind of risk, he would sneak down the hallway, open the door, drive the 10 or 12 miles over to debbie hawk's house, subdue her, bludgeon her, load her into the van and drive to fresno and get back to his house without getting any blood on him, without being discovered. >> so what did happen to debbie hawk? the defense floated this theory.
