Tatort S2010E04 - Kappl - 5 - Hilflos

The body of a comprehensive school student is found in an abandoned parking garage in Saarbrücken. After a fight, David fell off a ledge and broke his neck. In this case, detectives Kappl and Deininger are also investigating the victim's school. This is hard for Stefan Deininger, because he used to go to this school himself. The old multi-storey car park had already been a meeting place for the young people back then. David's classmates react to the death of their classmate with a show of indifference. His class teacher also confirms that David was an outsider. Yes, there were problems with other students, but she hadn't noticed anything for a while. Gradually it turns out that the teachers do more than just gloss over things.
The torment that David and his best and only friend Tobias were subjected to in class went far beyond the bounds of conventional bullying. Although Tobias, like David, was also a victim of attacks by his classmates, he quickly became the focus of the investigators. Tobias remains silent. He obviously knows more than he says, and the interrogations by Kappl and Deiniger become a nerve-wracking puzzle. While Stefan Deininger feels sorry and tries to understand the outsider's situation, Franz Kappl sees Tobias as the wanted murderer and tries to put pressure on him. But what reason should Tobias have to kill his best friend? And why is a whole class silent about the events?
