Abstract
Expanding Homicide Mobility Triangles: An Exploration of New Typologies Track: Law Enforcement and Criminal Justice Author(s): Elizabeth Groff Achieving a more complete understanding of the behavioral aspects of homicides has great potential for developing more targeted intervention and prevention strategies. One avenue to increase understanding is through the study of the spatial behavior of the parties involved. Mobility triangles have been used to describe the spatial relationships and develop a spatial typology of crime events (Rand 1986; Tita and Griffiths 2004). Mobility triangles enable the classification of crimes into types based on the relative locations of offender home address, victim home address and homicide location. This work extends the traditional mobility triangle by defining and analyzing the explanatory power of two new types of mobility triangles. The analysis compares the output of the two different typologies: (1) a traditional mobility triangle and (2) a distance-based mobility triangle. Results of the study shed light on the local nature of homicide events.
