If you are interested in real crime stories Aktenzeichen XY might be for you. I watched them all with my ex gf when I discovered them back then on Youtube. Nearly all shows from 1967-1997 can be viewed on Youtube. The newer once only partly.
The German subtitles for the old videos work quite flawlessly.
Every show has three films (cases) ranging from homicide to robbery and burglary. The other cases are not interesting really.
As an example, just wait a coupled of seconds until the film startshttps://youtu.be/PCvd6NsbFLc?t=384
