Prepare A Narrative Of The Scene

After evaluating the physical evidence the crime scene investigators then come up with a narrative story that might go along with the physical evidence that they have found at the crime scene. They need to keep in mind that months or even years later this case may go on trial. Some investigations do not go on trial as fast as others. With that being said the investigators need to make sure that they have an idea as to what they are going to say and write everything down because later on they might not remember with the other things going on. Their notes must present the full story of what they saw and any impressions the evidence gave them. As crime scene investigators they need to make sure not to mix up the evidence because that can cause the jury to come upon a different verdict. Everything should be done fairly.

Evaluate Physical Evidence Possibilities

When you arrive to a crime scene the following thought pop into someone's head which are What happened here, when did it happen, and what sort of evidence should be present? Some common questions that Criminal Investigators ask when they first get to a crime scene is:

• Are there visible footprints in the blood?
• Are there any signs of struggle?
• Is the blood spatter apparent?
• In what room did the shooting/stabbing/beating occur?
• Was the body moved?

Each crime scene may would have many different questions to go along with the scene that crime investigator ask and try to answer.

Initiate Preliminary Survey

Before entering the structure of a crime scene an exterior survey is needed. This is when someone would be walking around the exterior of the structure (which would be the crime in the scene itself) to see if any obvious evidence is apparent. Maybe like an open windows, damaged doors, ladders to get inside, etc. The first question we think to ourselves is "How was entry made to the structure?" After CSI comes into the room they start to make what is called a visual survey. This is when the CSI Agent will actually survey the actual room in which the incident that was reported took place. This is when the photo graphs come into play. This is also the time that they take to take any type of photographs of the crime scene. Then after they finish in the room that the action happened, they move onto the adjoining rooms to determine if the other rooms have any kind of information relating to the incident.
