Serial Murderers’ Spatial Decisions: Factors that Influence Crime Location Choice
Abstract
The outcome of German serial murderer spatial decision making was measured as the straight-line distance (km) between murderer home locations and each crime location (i.e. body recovery location). Geographic and series development data, as well as information on age, intelligence, motive, marital status, employment status, and mode of transportation of 53 German serial murderers was collected from police and prosecution service files and judicial verdict records. Potential effects of the aforementioned factors on spatial decisions were assessed. Results showed that 63% of the murderers lived within 10 km of their crime locations. Home-to-crime distance was negatively correlated with murderer age and positively correlated with murderer IQ score. Results also showed that the mode of transportation used by murderers had an effect on their spatial decisions. Results are discussed in terms of understanding serial murderer spatial decision-making and implications for police investigations.
INTRODUCTION
A limited amount of information is available regarding serial murderers’ spatial decisions. Existing research on this topic has been based primarily on American serial murderers,...
