Peter Kurten, a German who'd been sent to prison for deserting his comrades, sat in a cell contemplating what to do when he got out. He had no control within the prison walls and it drove him mad. The things that happened to him while in custody, unlocked oppressed sadistic feelings within Peter, and forced him to unleash a level of sexual deviancy on innocent victims in and around Dusseldorf, Germany, that no one will ever forget.
 
Young girls, women, and men would succumb to horrific attacks including being bludgeoned by a hammer and stabbed to death. In several instances, Peter admitted to drinking blood from his victims and needing the act of rape and murder to reach orgasm.

Had he not done so, 'The Monster' would have continued to keep the country locked in fear. for many more years.
