Geographical profiling also studies the behaviors of individuals in the neighborhood of the serial crime to identify the exact area and individual suspected to commit the crime.Geographical profiling is special in that it helps in investigation procedures by reducing the volume of possible factors that tend to identify the region and the offender of a particular crime. Geographical profiling is also very efficient as it assists in minimizing wastage of time and resources used in the investigation process (Spencer Thompson 2008, 53). Effectiveness of the geographical profiling relies on the scrutiny of a minimum of five serial crime cases reported occurring in the same geographic location. Analysis of the data obtained is done through environmental understanding and psychological know-how of the geographical profilers.Before geographical profiling can start, a geographic profiler needs to organize a number of possible guidelines that will help in the process. The first guideline involves the preparation of a geographic profile. This kind of profile assists the investigator in identifying the geographic epicenter of investigation. The geographic epicenter identifies the possible home and works location of the offender. In addition, geographical profiling helps in the identification of the common path often used by the offender. The second guideline calls for identification of catchment area of the within the possible crime site. The catchment area defines distribution of institutions, shops, and schools within the geographical profile. The catchment area further provides a detailed perimeter for investigation. The last guideline is the construction of maps related to the site of the crime. Maps also help in the strengthening of cases upon presentation in the courtroom. The map also provides evidence links between the previous reports of serial cases with the current under investigation (Youngs Canter 2008, p 26).
