I believe this is part of a series of stand-alone police procedurals about the Austrian national police (Landkrimis). It certainly isn't a horror film, as others here have noted. In fact it is questionable as to whether the tragic incident here would even result in a criminal conviction. However, the characters are interesting people in their own right and they portray life in a small town that seems to value conformity over nearly everything else. I would assess this as having more in common with an episode of the 1980s German television mini-series 'Heimat' ('Homeland') than either the police or horror genre. Like Heimat, it is certainly beautifully filmed as well.
