5 Steps of Processing a Crimescene
2. Photography
An officer must photograph the crime scene in order to be able to use those later in the investigation. They will become very crucial as the trial goes on.
3. Diagramming
The officer should diagram the crime scene. There should be measurements written down somewhere so that if anything in the crime scene is moved it will be documented as to where it was before. They should also make a complete evidence list.
4. Collection

Officer should collect all the physical evidence at the crime scene. They should make sure to find evidence that is unseen as well as seen. The evidence should be maintained as to not mess it up and so it can be used for the trial.
5. Process for fingerprints
The officer should check the area for any fingerprints that may be there. They must dust for fingerprints last because the powders they use to check for fingerprints contaminates the scene. This will make them able to see if there was a criminal at the scene.
1. Respond
An officer must arrive at the crime scene with a plan. The detective must be able to communicate with all of the other officers that have come to scene so as to see that everything goes as planned and all of the evidence is taken into consideration.
Exterior
The exterior crime scene should be checked first before anything. Extensive photographs should be taken of every side of the building. Impressions of any biological evidence should be taken down about the crime scene.
Surrounding areas
The surrounding areas of the crime scene should be documented. Any buildings, wooded areas, or fields. When photographing they should start from the center of the scene and work to the places around it.

Interior
When photographing the interior, the officer should start from either the point of entry or the point of exit working in. Then the officer should trace a path to where the crime happened so as they go along they can see any evidence leading up to scene such as blood or footprints. Then they should process the body making sure not to move the body or alter it in any way. Then once the body is removed the fingerprints can be processed.
