Information about the identity of the person who committed the crime begins to collect from the place where the crime occurred. Examining a crime scene is a complex activity. After all, a criminal leaves an invisible trace of his psychological state, mental properties and functions at the time of the crime.

The abilities, intelligence and skills of a criminal can be traced in exactly how he commits a crime, and what methods he uses to hide it. Here you can determine the professional affiliation, habits and occupations of the offender.
In general, crimes occur in circumstances of strong influence on the psyche of various factors, both internal and external. It may be fear of being discovered at the crime scene and limited time. The reason lies in the excess of emotional and neuropsychic stress of the offender. For this reason, thinking becomes harsh, perception becomes worse, the level of attention to the actions being taken drops. The consequence of all this can be the implementation of even unplanned actions by the criminal.
The offender makes changes to the very scene of the crime, which, in turn, affects his psyche. His reactions to stimuli become inadequate. To conceal the crime, the attacker can destroy some traces and use staging. Often they are aimed at leading the investigator to thoughts of a less serious atrocity.
