When the call comes in that a crime has been committed, the police are dispatched to the crime scene. When the police arrive on the scene, they must take control by arresting any suspects and searching for witnesses/victims. If the scene is unsafe, first responders must secure the area. If someone gets hurt, they should call medical personnel as soon as possible. The first police officer on the scene is usually in charge until a criminal investigator arrives at the scene. Depending on the crime committed, the crime scene could be as small as the inside of a building or as large as the entire neighborhood. The entire crime scene area must be secure so that the evidence is not tampered with by anyone. The responsible police officer may initiate a search for further evidence so that it can be secured by the time investigators arrive on the scene. There are five different search methods; point-to-point movement, widening circle, narrowing circle, zone or sector search, and strip or grid search (Lushbaugh and Weston, 2011). Each search is performed under different circumstances which all depend on how large the crime scene is and whether it occurred inside, outside, inside a building, etc. Once a criminal investigator arrives, the police should secure the area so the investigators can do their work. Investigators will enter the crime scene and have some equipment on hand to preserve evidence. Evidence will not be removed until proper procedures are followed to avoid jeopardizing it. They will number each piece of evidence and photograph it. For example, if there was a drop of blood on the ground, a number would be placed next to it and a photo would be taken. Images will be viewed close up, in the center of the paper, quickly and can be documented precisely. Investigators can go to the crime scene and look for any evidence that may have been missed. Overall, crime scenes committed inside a building are a little easier to handle than an outdoor crime scene. Department of Justice References. (n.d.). All about forensic science.
