David Canter suggested that people reveal themselves through the locations where they commit crimes, and geographical profilers focus on where crimes are committed. Geographical profiling involves analyzing the location of a connected series of crimes, and looking at factors such as the spatial relationship between the different crime scenes and what this these reveal in relation to the perpetrator. For example, Rossmo (1997) refers to offender behaviour as having ‘hunting patterns’, and through examining the locations of crime scenes and their spatial relationship to each other, we can know more about where the criminal is located.
