This newsletter offers an outlet for scholars, practitioners, and policy makers to learn, share, and collectively address topics of mutual concern. Analysis. Geographic profiling focuses the search for suspects using a combination of environmental criminology theory, research on offender spatial behavior, and mathematics, which has been incorporated into geographic profiling software called Rigel by Environmental Criminology Research Inc.

This article outlines the background of geographic profiling, discusses training in the methodology, and concludes with a case example that shows the application of geographic profiling in an operational case.

Rossmo began studying geographical profiling as part of his PhD studies at Simon Fraser University (British Columbia, Canada). Velarde, L. (2004, April). Geographical profiling involves analyzing the location of a connected series of crimes, and looking at factors such as the spatial relationship between the different crime scenes and what this these reveal in relation to the perpetrator.

While this may initially look similar to a hot-spot map of the crimes, it is actually showing different information: where the offender is likely based rather than where they commit their crimes. High-profile cases Rossmo worked on include the Beltway Sniper, the Zodiac Killer, and the Golden State Killer. Also known as behavioral analysis, this aspect of the field of psychology offers law enforcement practical tools with which to apprehend serial criminals. This was the first physical evidence in the investigation and it was helpful because any suspect who was identified in the investigation could now be compared to the scene DNA. Professor David Canter, PhD, AcSS, FAPA, FBPsS, C.Psychol. (1997). Here, we use two data sets - one historical and one modern - to show how it can be used to locate the sources of infectious disease. A geographic profile can also be used to prioritize areas for directed police patrols or area canvasses. It was used to aid FBI and local agencies’ investigations as early as the 1940s but only formalized in the mid-1970s. Geographic Profiling Geographic profiling is an investigative methodology which uses the locations of a connected series of crimes to determine the most probable area of offender residence (Rossmo, 2000).
