Well since I am studying criminal investigations I will tell you how they go through with a crime scene from the time they get the 911 call. As we all know it does starts with a 911 call and someone reports the problem and the police dispatcher will send someone out to the scene and the first one on the scene is a first responder and fire rescue squad will also come out and try and do what they can do and if they have someone on the team that is able to pronounce they will pronounce the victim dead upon arrival. Sometime in between the first responder and the fire rescue squad the Crime Scene techs will get the call to come to the scene. They only interview the first responder and the fire rescue squad. They would ask them questions about the scene and how it was when they got there and that will end up in the later final report they will right. Before the techs get there most of the time there is a perimeter set, you can have a big perimeter it’s easier to make it smaller than make it bigger so you should make it big depending on the situation.
Next from all that is the walk through if for a home. They would need to know where the victim is and the escape routes. Once they have that covered they will start taking there measurements and photographs of the scene and
