Abstract |
The purpose of this research is to further understanding of how environmental factors impact on the distance an offender travels from their home to their crime scene - the so called 'journey-to-crime' (JTC.). Currently, Geographic Profilers rely on relatively generic JTC research to form inferences about the likely distance travelled by an offender, and may be missing the opportunity to make a more bespoke assessment which takes these factors into account. 1186 cases of female stranger sexual assault (Study 1) and 124 cases of stranger homicide (Study 2) were analysed. Euclidean measurement of distance was provided from the offender's recorded home to 3 crime site locations: (1) the initial contact with victim, (2) the assault/murder, and (3) the victim release/body disposal. Each crime site location was coded according to: (a) population density and (b) urban or rural. Initial analysis examined the median distance travelled from an offender's residence to the three different crime site locations. Significant findings for stranger sexual assaults indicated that the initial contact location was significantly further from an offender's residence compared to the sexual assault and victim release location. This was not replicated for stranger homicide offences. Both sexual assault and homicide cases revealed that the distance travelled to the 'initial approach' location did not differ according to population density, or whether the location was urban or rural. Regarding 'sexual assault' locations, offenders were found to travel significantly further from their home to attack their victim in low population density and rural areas. Language: en |
