casey jordan, if all that is true, is that game, set, match? >> i would have to think so, because dna by itself you could argue there was human error, that it was tampered with in some way, that it was a set-up. but, based on the totality of circumstances, all of those card swipes, all of that dna and, you know, evolving information about where she was found, things coming forward about his behavior with the scientists, you know, being a little bit effecious and rude at times really supports the idea of the sort of person who might have done this was a control freak who snapped in some sort of dissent with a can-worker. >> casey, by the way you are criminal olist joining us. thank you for weighing in. robert bond, you specialize in workplace violence. i don't really understand that term. to me that's violence that occurs in the workplace. that doesn't necessarily mean there is some other motive involved. we are hearing reports people have called clark, the suspect, a control freak by some others in the lab, that he was rude according to one co-
