Tatort S2006E11 - Odenthal - 37 - Revanche

Gerhard Brenner is found shot dead in his house, there are no traces of a break-in. Brenner was a widow, a retired bank clerk, recognized as a football club coach. Lena Odenthal's and Mario Kopper's investigations initially focus on his unemployed son Udo. He has always disappointed his parents and now only gets in touch with his father when he wants money from him. But there wasn't much he could get from his father. A few years ago, however, Brenner was suspected of having been involved as an informant and client in a robbery of the bank where he worked. Two of the robbers were then caught and convicted, the loot was missing. No entanglement could be proven to Gerhard Brenner.
However, on the day of the murder, Thomas Reuter, one of the two robbers, was released on parole. Reuter wants to start a new life, work for his stepbrother Jochen Galowski and be reconciled with his wife Petra. Thomas Reuter denies having anything to do with Brenner's murder. In general, he maintains that Brenner was not involved in the bank robbery. But the deeper Lena Odenthal delves into the Gerhard Brenner case, the clearer it becomes that his murderer suspected the loot from the bank on him. Lena will only find him if she can solve the mystery of the unknown accomplice.
