Crime Scene Investigation

A crime scene refers to a place where a crime has occurred. The purpose of crime scene investigation (CSI) is to analyze the complete scene and catch the culprit based on the pieces of evidence collected from the place of crime. The people involved in this process are referred to as crime scene investigators.
