Securing The Crime Scene Essay

1160 words - 5 pages

When the call comes in that a crime has been committed, the police are dispatched to the crime scene. When the police arrive on scene, they need to take control by apprehending any suspects and looking for witnesses/victims. If the scene is not safe, the first responders must secure the area. If anyone is hurt, they should call for medical personnel as soon as possible. The first police officer on scene is usually in charge until a criminal investigator arrives on scene. Depending on the crime committed, the crime scene could be as small as the interior room of a building or as large as the whole neighborhood. The whole crime scene area needs to be secure so that evidence is not tampered with by anyone.
The police officer in charge can start a search for more evidence so that it can be secured by the time investigators arrive on scene. There are five different search methods; the point-to-point movement, ever-widening circle, ever-narrowing circle, zone or sector search, and the strip or grid search (Lushbaugh, and Weston, 2011). Each search is used under different circumstances that all depend on how large the crime scene is and if it has occurred indoors, outdoors, inside of a building, etc.
Once a criminal investigator arrives, the police should have the area secured so the investigators can do their jobs. Investigators will enter the crime scene and will have some equipment to preserve evidence on hand. Evidence won’t be removed until proper procedures are followed so that it is not jeopardized. They will number each piece of evidence and take pictures of it. For example, if there was a drop of blood on the ground, a number would be put next to it and a picture would be taken. The pictures will be up close, far away, and on different angles to ensure that every detail can be noted; nothing can be missed. Each photograph has a lot of information included with it such as: when, where, what, etc. (Lushbaugh, and Weston, 2011). This is very crucial information to note so that the pictures can be distinguished and easier to identify.
Sketches are also made along with the photographs that were taken. This is done to make the crime scene as realistic as possible. The sketch is of the crime scene as a whole and includes exact measurements of how far the evidence was from certain points inside the crime scene, how far it was away from the door (if the crime scene was inside a home), etc. Apart from sketches, video documentation of a crime scene may also be kept (Layton, 2005). This helps to put all the pieces of the crime scene together so it can be better understood.

The crime was committed in a closet in the McCormick building of the first floor.
