INTRODUCTION TO CRIME SCENE RESPONSE

Most police investigations begin at the scene of the crime. The scene is simply defined as the actual site or location in which the incident took place.

It is important that the first officer on the crime scene properly protect the evidence.  The entire investigation hinges on that first person being able to properly identify, isolate, and secure the scene.

The scene should be secured by establishing a restricted perimeter. This is done by using some type of rope or barrier.  The purpose of securing the scene is to restrict access and prevent evidence destruction.  Once the scene is secured, the restrictions should include all nonessential personnel.
