Unbelievable. Only 10-15 minutes by car from where we live, in a small town of only 27.000 or so inhabitants, a 17-year old kid shot dead 16 persons. It seems he took the gun from his house (his father is a member in a gun club), went to the school and started by getting into a classroom and shooting 5 kids in the head. The he continued through other classrooms killing more kids and teachers. Eventually police showed up and the kid fled the scene. He forced a driver to take him to some town 40km south. There he got into a car dealership where he shot a salesman and a customer. A shootout with the police ensues, the kid is hit in the leg and then he kills himself.
Words fail me :-( A more detailed description in this article in Spiegel.
