Introduction
Led by Prof. Santtila, I did comprehensive research on crime committing distances within Finland across several crime types, creating distance decay functions to be used for geographic profiling by Finnish police. (I also tested said approach in several live crime series.) Results of research: unplanned/impulsive crimes tend to be done relatively close to place of residence and this can be used by police. (Routledge "Psychology of Arson" p. 127 has typo: we found 0.88 km, they print 88 km)

Article
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...
Article
Unlabelled: Residential location of a criminal can be predicted statistically [M. Laukkanen, P. Santtila, Predicting the home location of a serial commercial robber, Forensic Sci. Int. 157 (2006) 71-82]. Examined were: accuracy of the technique for urban burglary series, correlations between way of committing burglary and distance and use of those...
Thesis
Full-text available
The results of extensive research concerning offender’s home to crime location distances in several crime types are similar: the majority of such distances are relatively short, less than 5 km (see Table 1 for a review). The phenomenon of diminishing spatial interaction as one moves away from familiar places has been named Distance Decay (Lowe & Mo...
Data
Image has a table of empirical distance decay functions of several crime types in several Finnish cities.
Article
We explored (1) distances between home and offence in homicides and rapes; (2) whether these distances differed from each other; and (3) whether offence features were associated with distances. The sample consisted of solved homicides (N = 40) and rapes (N = 37) from Finland with co-ordinates for offence and offender home locations and information...
Article
Residential location of a serial offender can potentially be predicted by using models created from home to crime site journeys of solved crimes in the area [N. Levine, Journey-to-crime estimation, retrieved 23 October 2003 from http://www.icpsr.umich.edu/NACJD/crimestat/CrimeStatChapter.9.pdf, last visited 1 February 2005]. Aims of this study were...
Article
The purpose of the study was to test the potential utility of a geographical profiling approach for three separate series of rapes committed by a single offender. Two different mathematical distance-decay functions using either a normal distribution with a mean distance and standard deviation based on previous research or a truncated negative expon...
