>> reporter: there is an art to the business of criminal defense. and it would take an artist to repaint the prosecution's dark portrait of jason young. so what could the defense attorney, mike clinkson, do. well to begin with, he told the jury, he agreed with the prosecution. jason young was not a good husband. >> he acted at times like an immature jerk. but that does not make him a killer. >> reporter: the defense was not about to make any more concessions, mind you. the jewelry box in the bedroom there was dna on it. didn't match michelle or jason. suspicious activity at the hotel, there was a fingerprint on that camera, and it wasn't jason young's. and, there wasn't any forensic evidence that tied jason to the crime scene. there was no blood in his car. there was not a scratch on him.
