I didnt know serial killer shad much to be proud of... why is it an insult? i really canot comment further until you tell me why. again.. if he was a mass murderer he would have likely went out in a blaze of glory. To turn from an agitated family man into a rampaging and yet controllled murderer then to turn it back off again and kiss your wife goodnite and tuck your kids in is the kind of behavior that only serial killers portray. Mass murderers would go for the blaze of glory to lash thier pain out on everyone else and get caught. serial killers are smart, have thier MO, and are extra careful as so they can get away. This guy is clearly a serial killer.
