Labelled Belgium's most notorious criminal, Dutroux abducted, sexually assaulted, tortured and killed four young girls (and spared two more from death) between 1995 and 1996, as well as killing an accomplice, but was unthinkably allowed to escape from negligent police custody. He was recaptured, but his escape was a national embarrassment and caused the revision of the entire Belgian police system.
