Geographic profiling is a crime analysis technique that uses crime and other locations to focus the search for the offender. Combined with the proper strategies, a geographic profile can be used to provide leads and produce a prioritized list of suspects for investigators. This presentation outlines the geographic profiling process and includes discussion on series identification, spatial and temporal patterns, production of a geographic profile, creation of investigative strategies, and multi-parameter suspect prioritization. Key points are demonstrated with case examples.
