DUISBURG — 1976 · Serial Murder

The "Ruhr Cannibal" Case

SolvedSources: ALast updated: 14 October 2026

Joachim Kroll carried out a series of murders targeting women and children in and around the Ruhr region between 1955 and 1976. For years the cases were not linked, and other people were wrongly suspected or even convicted for some of the killings. Kroll was arrested on 3 July 1976 at his apartment building in Duisburg-Laar during a search for a missing child. Although he confessed to many more killings, after a 151-day trial the court on 8 April 1982 sentenced him to life for eight murders and one attempted murder. Kroll died of a heart attack in prison in 1991. The case prompted debate over why links between serial crimes had been missed in West Germany.
