The police found the body of Marion Kettner dismembered in Kroll’s house. Some of her parts were in the fridge, and Kroll was in the process of cooking a small hand on the stove. The entrails of the girl were found stuck in the waste-pipe. Kroll was immediately arrested and he confessed to thirteen murders. He was labeled the Ruhr Cannibal, Ruhr Hunter, and the Duisburg Man-Eater by the German media. At his trial, Kroll said that he often sliced portions of the flesh from his victims to save money on his grocery bills. In 1982, Joachim Kroll was convicted of mass murder and sentenced to life in prison. He died of a heart attack in 1991, in Rheinbach.
