This fascinating documentary series shows how criminals reveal who they are & where they live by the locations they choose for their crimes. It is presented by Liverpool Universities Professor David Canter, who invented this technique of geographical profiling in 1986. He explores the parallels between a criminals psychological journey & the actual paths they follow. Are they travelling far in a quest to rid themselves of their inner demons? Are they creating a protective web in which to trap their victims? Or do they set out on marauding trips in an attempt to achieve a quick gain?
