The most constant and precise in terms of the psychology of criminal behavior is its profile. It displays many of parameters of the criminal activity. For example, the usual method of committing the crime, geospatial crime activity data and other small dependence which together correspond to the profile.
The presence of certain behavioral traits, with a certain degree of probability, may indicate that the entity may be involved in the event. This principle formed the so-called group behavioral analysis.

Therefore, in the criminal practice often noticeable coincidence for some behavioral parameters in different subjects ever participated in a single event. Analysis of group behavioral profile allows you to define accomplices, partners, with no apparent links between them.
