Explain The Key Steps In Securing A Crime Scene
The key steps in securing a scene
In this essay I will be explaining the key steps in securing a crime scene. Comparing and contrasting methodical systematic search patterns and which one I think would be most useful. I will explain why I think note taking, photography and diagramming is important to a crime scene. Last, I will explain what the safety issues that are involved when processing a crime scene.
As a first responder to a crime scene you must make sure that the crime scene is contained with as little disturbance of evidence as possible. The area may have people around it trying to see what is going on. Some of these people could be considered witnesses(Bucholtz,Ann; Lewis, Jon).

One type of search method is the grid search. in a grid search the area is divided into north and south, East and West strips, allowing a secondary search of each area from a different direction. It is useful when teams are used to search a large area for hard to find items. Another search method the concentric or spiral search pattern(Bucholtz,Ann; Lewis, Jon). A concentric or spiral search follows a circular pattern from outside in or in side out. This method is useful if resources are limited, the area is relatively open, and the search is for large items, such as a body, gun, safe, …show more content…
Notes should follow a chronological order and be clearly and legibly written. Notes must be specific, avoiding general terms, such as, "near". Specific measurements should be used instead. These notes can be subpoenaed in court and will be judged on their appearance and content.
The purpose of photographing is to create a visual record of the scene and the evidence collected(Bucholtz,Ann; Lewis, Jon). Each view has a separate purpose. Overall views are taken to show the largest view of the scene possible. Mid-range views depict the relationship between items. And close range views document the items of evidence individually including serial numbers, tags or other details.
The diagram or sketch records the location of physical evidence as well as their relationship to other objects at the scene. The sketch includes measurements of the sizes of objects and distances between them. Sketches are used in combination with written reports and photos to document a scene. Sketches are important because they can cover a large area and be drawn to leave out unnecessary
