Tatort S2010E16 - Keppler - 8 - Heimwärts

A young geriatric nurse, Anna Kowski, was murdered in the laundry room of her apartment building. The first clue leads inspectors Saalfeld and Keppler to the Holst family, whose grandpa Karl, who was suffering from dementia, was the last patient Anna had taken care of the night before. Ms. Holst reports that there was a serious argument between Anna and her jealous boyfriend Daniel in front of her house. When the inspectors want to question Daniel Bergmann, who works in a funeral home, Keppler recognizes the young man he had seen at the crime scene the night before. Daniel initially stubbornly denies that Anna wanted to break up with her boyfriend, but then admits there had been a fight in Anna's apartment. However, he denies the murder and instead incriminates the head of the nursing service for which Anna had worked.
Mike Breuker is said to have exploited his employees and paid them poorly. It seems that Anna, who is very popular with her patients, no longer wanted to put up with this and blackmailed her boss with her knowledge of false health insurance bills... Shortly afterwards, Elsa Kluge, another patient of Anna's, was found dead in her house. Although the cause of death remains unclear at first, detectives find out that she has left all of her belongings to Mike Breuker's nursing service. A connection between Breuker's semi-legal machinations and the murder of Anna Kowski is becoming increasingly likely - did he kill the nurse? In the meantime, the situation is getting worse for the Holst family. Caring for the grandfather is a heavy burden for the couple.
More and more daughter Svenja has to step in after school to take care of her exhausting grandfather. The tense situation increasingly leads to disputes. A special relationship develops in the course of the investigation between Karl Holst and Inspector Keppler, who finally notices signs of domestic violence in the old man. But for the Holsts, sending grandfather to a home is out of the question – especially since they don't have enough money. When they decide with a heavy heart to sell the house, they make a terrible discovery: Grandpa Karl signed the house over to Mike Breuker weeks ago in exchange for a place in his future nursing home...
