Mord Im Spreewald [Murder in the Spreewald]

Many years ago, a brutal murder took place here, which has not been solved to this day. 4 youths were camping right here but only one came back alive...and he never spoke a word from then on...was he the killer? It was never found out what exactly happened that night in the middle of the dark Spreewald. Is the culprit still out there? Can you find out more? Are you on the trail of the culprit? Or is he on to you...
