­Crime scene investigation is the meeting point of science, logic and law. Processing a crime scene is a long, tedious process that involves purposeful documentation of the conditions at the scene and the collection of any physical evidence that coul­d possibly illuminate what happened and point to who did it. There is no typical crime scene, there is no typical body of evidence and there is no typical investigative approach.

Police officers are typically the first to arrive at a crime scene. They arrest the perpetrator is he's still there and call for an ambulance if necessary. They are responsible for securing the scene so no evidence is destroyed.
