IngentaConnect Distance travelled and offence characteristics in homicide, rape,...

Abstract:

Purpose

We aimed (1) to describe distances from home to offence locations (journey-to-crime) of offenders in difficult-to-solve homicides and rapes as well as robberies against businesses; (2) to see whether the distances in these offences differ from each other; and (3) to test whether selected features related to the offence would be associated with the distances.

Methods

Lists of difficult-to-solve (DTS) homicides (N=99) and rapes (N=56) as well as robberies against businesses (N=275) from the city of Milan (Italy) were acquired. The collected data consisted of home and offence location coordinates with information on the behaviour of the offenders (for rapes and homicides). The journey-to-crime functions were calibrated using the journey-to-crime module of CrimeStatIII^©.

Results

Most distances were short. In homicides, distances were below 1 km, in rapes below 2 km whereas in robberies against businesses almost 6 km. Some crime features were correlated with the distances in rape and homicide cases. Combining the behavioural information to a spatial behaviour measure allowed for better prediction of travelled distances compared to using single variables.

Conclusions

The results have practical implications for crime investigations as the crime features explored were, as a rule, such that they would be known by the police prior to the offender being identified. A general theoretical framework for binding together journey-to-crime distances and offender crime scene behaviour and other important crime features is needed.
