S30E27 : Köln - Martinsfire

The body of a four-year-old boy is found in a working class area. An autopsy reveals posthumous injuries. Schenk suspects they're dealing with a psychopath preying on the weak. Meanwhile, Max befriends Mirko, an emotionally neglected eight-year-old he suspects knows more than he's willing to admit. As they investigate the murder, they are drawn further into the world of children's fears, and grown up's dreams. Directed by Niki Stein, 1999.
