Er überlebte den Maskenmann – und brachte ihn Jahre später zu Fall | stern TV

Throughout Germany, he became known as the "Masked Man": a perpetrator who abused children and murdered four young boys. He remained undetected for almost 20 years and has since been sentenced to life imprisonment in France. Martin Wichmann was one of his victims. At the age of ten, he was attacked in his own home. What remains is fear, anger, and the memory of the perpetrator's voice. Years later, he was able to identify it—giving the police the crucial lead. Subscribe to our channel and never miss a video!
