Der Pass

Tipped off by the killer's horrific photofit, the investigators unearth the Krampus legend - a symbolic creature infamous for punishing the naughty and unworthy. This leads them to Sebastian Brunner, head of a rural sect, whose books on the end of civilisation seem to have inspired the killer. Through the cult leader, Ellie and Gedeon manage to contact the perpetrator via the internet. This achievement, however, can't stop the murder of a YouTube starlet on a lake near Salzburg.
