Criminal Geographical Targeting Model

develop additional information concerning the offender such as: any familiarity the offender may have, the route in which the offender may have taken, or any alternative routes for the offender (Pethrick, 2014). These developments permitted the use of more computer based technological advancements like Geographic Information Systems (GIS). In utilizing these systems, the information garnered will display a grid layout of a “hunting ground” for the suspected serial offender. Another tool used in trying to locate geographic areas where the offender has used can be completed through the use of the Criminal Geographical Targeting (CGT) model. This model uses algorithms to propose a computer simulation of the offender and presents two elements: are: the encounter and the dumping ground (Vronsky, 2004). In using this approach a preconceived analysis can be made about the location of the crime scene.
Having an educational background of those who profiles has become a requirement in recent years
A signature of the process of the murder is what brings about a psychological profile that helps identify serial killers. Some examples of signature behaviors are posing the body, leaving markings on the victim, and crime scene staging (Papazian, 2011). Identifying a signature facilitates law enforcement by conceptually allowing them to link both known and unknown offenders with their crimes. More importantly, the significance of a signature behavior enables the ability to associate a match or identification rather than an individuation of a particular source. Therefore, crime scene evidence can produce a match such as a carpet fiber that is consistent with an offender or an exclusionary source of evidence which identifies the offender as the sole contributor of the evidence in question such as
