What is a "Crime Scene"?

A crime scene can be anywhere a crime took place, or anywhere evidence relating to that crime is, or may have been.  For these scenes, evidence may be anything that helps reconstruct events, or connects a person to a scene, item, or another person.

In short, crime scenes can be anywhere, and evidence can be anything, depending on your case. You must ensure the forensic investigation is thorough, and overlooks nothing at the start

How Many People Are Needed to Handle & Process a Scene?

 

There is no set number, and each scene is unique in what it requires.  A team approach is always best, especially for larger or more complex scenes.

 

To limit contamination, it is imperative to minimize how many have access to the scene, and to secure the scene as soon as practicable. 

 

At the same time, keep in mind, no one person can be an expert in everything. We all need support and a second set of eyes.  Ensure any expertise needed at the scene, is a part of the team. Police, Fire, EMS, and any others need to work collaboratively to maximize scene safety and processing.

What Personal Protective Equipment (PPE) Do You Need?

You must continually evaluate what PPE to use based upon the potential threat from the scene to you, and the threat from you to the evidence.

 The most common PPE are gloves (medical grade), footwear covers, and tyvek suits (A60). However, at times, additional forms of breathing protection in the form of respirators or self-contained breathing apparatus may be required.

 

You must understand the threats before you go in, and always begin at the highest level that may be needed for the scene! 

The two most basic types of threats are:

  • threats from scene (biological, chemical, explosive, etc.) to you, and

  • threat of you (contamination, destruction, etc.) to the scene!
