Tatort S2008E28 - Saalfeld - 3 - Unbestechlich

The attractive waitress Ellen Krüger was murdered in her apartment. It turns out that the young woman was a drug addict. Surprisingly, Matthias Krupp, a colleague, is at the center of the investigations of chief inspectors Eva Saalfeld and Andreas Keppler. He is looking for his 17-year-old daughter, Amelie, who ran away from home. Did Krupp find out that Ellen Krueger was selling his daughter drugs and therefore killed her? Amelie reappears, but at the same time Matthias Krupp is found dead. A trail leads to another colleague of the commissioners. Stefan Dirks is a drug investigator - does he deal in drugs? Had Matthias Krupp become a danger to Dirks by looking for Amelie and therefore had to die? But Dirks has an alibi for the time of the crime.
