Spatial Patterns

Abstract

D Canter and P. Larkin's (1993) Circle Theory of Environmental Range was designed as a means of using the geographical locations of an individual offender's known offences to predict the approximate site of the offender's residential base. Canter and Larkin obtained support for their theory from an investigation of spatial patterns in serial rapists' offences in a few British cities. The present study sought to assess the generality of Circle Theory by examining spatial patterns of serial offences in three crime modalities in the Australian environment Data on 24 serial rapists, 22 serial arsonists, and 27 serial burglars were extracted from the NSW Police Service's files of criminal records. For each case the positions of offences and the domestic base were plotted on a scaled street map. Using a technique defined by Canter and Larkin a circle was constructed to represent the offender's hypothetical criminal range. In most cases of serial rape...
