Tatort S2006E30 - Batic - 44 - Das verlorene Kind

Unnoticed by the public, a person is being held captive in a flat and finally found after years of martyrdom. That's what the press says. After the murder of 67-year-old Adalbert Kirchner, the Munich chief inspectors Franz Leitmayr, Ivo Batic and chief inspector Carlo Menzinger met a cruel fate: tied to the bed, the severely disabled 31-year-old Hans vegetated - isolated from the outside world - in his parents' apartment to himself. Hans is not registered, he never went to school. Superintendent Carlo Menzinger was investigating a vague suspicion and found Hans through strange noises during the night. Hans' sister Sabine Schmiedinger sees her brother in the psychiatric ward again, sedated with medication.
The responsible medical team around the doctor Jeanne Degert and the ambitious Dr. Klein wants to examine Hans thoroughly and explain that Sabine has no right to take in the disabled brother until the guardianship has been clarified. Franz Leitmayr and Ivo Batic have to admit that Hans is suspected of having killed his father. Sabine lives with her husband Dietmar Schmiedinger on the outskirts of Munich. The sporty social worker teaches at a technical college. Sabine has fulfilled a lifelong dream by creating her own kindergarten. Old Kirchner and his daughter were at odds. When Sabine's mother died five years ago, her father wanted Sabine to move back home and take the mother's place in taking care of Hans.
But Sabine didn't want to, she was newly in love and about to build a life of her own. The father felt betrayed and did not appear at the daughter's wedding. For the press it is clear: 30 years of torture and imprisonment – then the son will take revenge on his own father. Jeanne Degert's report confirms that Hans would be capable of such an act. But Sabine realizes that an antique clock is missing from the apartment. Was it a robbery? The officers search the antique shops. In fact, such a watch was sold, but two years ago and not by an elderly gentleman, but by a foreigner. Leitmayr comes to the conclusion that the relationship between father and son was very different from what it first appeared, because Hans loved his father.
