Blutspuren

The story was loosely inspired by a real case from several years ago - the murder of eleven-year-old Josef Neumann. The 24-year-old perpetrator, Jaroslav Papez, met the boy in Prague's Metro cinema, where the man worked as a projectionist. Papez lured the boy into the projection booth under the pretext of watching the film Kommissar Maigret sieht rot! (1963), which was not allowed for children. Papez then abused the boy in the booth and subsequently began stabbing him. At the same moment, the audience in the auditorium was watching the film. However, because the film reel was interrupted during the rampage and unsuspecting spectators began to whistle in displeasure, Papez returned to complete the murder later. He subsequently hid the child's dead body in a shaft under the projection booth. Jaroslav Papez was caught five days after the murder and was sentenced to death during the trial.
