At the crime scene, a criminal investigator may note that there are more than what they see at the moment of their arrival. In fact, two or more crimes may appear. All this depends on how and where the compensation has been made. Such scenes are considered as primary or secondary classifications. The primary crime is the place where the actual offense was committed. The presence of the secondary offense is related to the offense in some way, in form or form, but not the place where the indemnity was committed.
In a jewelery store, for example, the shop is the primary scene, while the thieves are fleeing car and apartment for secondary scenes. As a murder, the victim's home that the offender was shot or shot was the primary crime. If the perpetrator used the victim's car to ship the body and landed it in a nearby lake, the point at the bottom of the van and the lake where the victim was thrown would have considered the secondary offenses.
Generally, primary scenes use more trace than secondary scenes, but not always. Sometimes the only offense CSI has to do is the secondary scene – a place at the lake where the offender laid the victim's body. In such circumstances, forensic detectives may not know the primary scene where the murder occurred and use the traces found in the secondary scenes to help them identify the perpetrator's identity or locate the scene of the primary crime. They can also benefit from the expensive tailored fibers found on the victim to identify the manufacturer, the seller, and especially the list of buyers or places where the particular suit was sold. This can shorten the center of the investigation and the leading authorities to the site of primary crime and bring the perpetrator to court.
