WaPo Duisburg S02E05 - Angelausflug

A fisherman is reported missing by his wife and shortly afterwards found dead in the Rhine by the WaPo.

The couple had been camping in the nature reserve with a friend. A crime of passion has not been ruled out, especially since the wife insists that her husband had been involved in a heated argument with another fisherman, a sinister-looking man, about the remote fishing spot shortly before his disappearance.
