Crime Scene from WikiPedia:

A crime scene is a location where an illegal act took place, and comprises the area from which most of the physical evidence is retrieved by trained law enforcement personnel, crime scene investigators (CSIs) or in rare circumstances, forensic scientists.

Strictly speaking, a crime scene is a location wherein evidence of a crime may be found. It is not necessarily where the crime was committed. Indeed, there are primary, secondary and often tertiary crime scenes. For instance, the police may use a warrant to search a suspect's home. Even though the suspect did not commit the crime at that location, evidence of the crime may be found there. In another instance, an offender might kidnap at one location (primary crime scene), transport the victim (the car being a secondary crime scene), commit another crime at a distant location (murder, for instance) and then dispose of the body at a fourth scene.
