This paper presents the first attempt to integrate four distinct approaches to solving crimes, all of which have proven their value when applied independently, namely: (1) geographic assessment, (2) social networking, (3) crime pattern analysis, and (4) physical description match. The system that integrates these four search techniques, called PerpSearch, takes a description of the crime, including its locations and all other known aspects (e.g., physical characteristics of suspects, vehicles, etc.), and runs it all through the PerpSearch engine components, where they are combined to produce a score for each potential suspect. By using past data on crimes prior to solution and comparing the results against the eventual known perpetrators, the system can be fine tuned and validated. A prototype has been implemented using current Alabama criminal and demographic databases.
