Crime Scene Forensic Analysis: Differentiating Between Primary and Secondary Crime Scenes
At the scene of a crime, the criminal investigator may notice that there is more than what they see when they arrive. In fact, there may be two or more crime scenes. All of this depends on how and where the crime was committed. Such scenes are classified as either primary or secondary. Tea main crime scene it is the place where the actual crime occurred. FOR secondary crime scene is the place in some way, shape or form, that is related to the crime, but it is not the place where the crime occurred.
In a jewelery heist, for example, the store is the main scene, while the car and the apartment from the thieves’ escape are the secondary scenes. In a murder, the home of the victim who was stabbed or shot by the offender is the main crime scene. If the perpetrator used the victim’s truck to transport the body and dump it into a nearby lake, the truck and the point on the lake where the victim was dumped would be considered secondary crime scenes.
In general, primary scenes contain more useful clues than secondary scenes, but not always. Sometimes the only crime scene CSIs have to go through is the secondary scene – the spot on the lake where the perpetrator dumped the victim’s body. In such circumstances, forensic investigators may not be aware of the main scene where the murder occurred and therefore use clues found in secondary scenes to help them establish the identity of the offender or locate the main crime scene. They can also take advantage of the fibers of an expensive bespoke suit they found on the victim to identify the manufacturer, the seller, and ultimately a list of buyers or places where that particular suit was sold. Doing so can shorten the focus of the investigation and lead authorities to the main crime scene and bring the offender to justice.
