How to preserve crime scene?
Once the crime scene is safe, it is to be preserved. First, it should be enclosed, e.g., by a barrier tape. Hess, Orthmann, and Cho (2016) advise first responders to make the crime scene as big as possible because it can be shrunk at any point, but it cannot be extended once it is set up. Based on surveys, these authors also provide a list of what first responders should and should not do. The first responding officer should establish one single point where the crime scene can be accessed.
What is a walk through in crime scene investigation?
119) is to be performed to assess if some physical evidence requires immediate action and prepare a preliminary reconstruction theory. Next, crime scene documentation starts. It is an ongoing and the most time-consuming component of the crime scene investigation (Gardner, 2012). Documentation implies describing and depicting every possibly relevant detail. Miller and Braswell (2010) point out four parts of such documentation: taking notes, taking pictures, filming, and sketching. All four should be present, as they are not interchangeable. Finally, the stage of physical evidence collection begins (although the stage of documentation does not stop but continues throughout the crime scene investigation).
What is the goal of an investigation?
The goal of an investigation is to establish the truth about a crime—w ho committed it, how, and why. A crime scene if the first place to look for theories in this regard as well as for evidence. To take from the crime scene as many valuable data as it can offer, the first emergency service employees who arrive at it should make sure that it is safe and preserved. Then, investigators should document as much relevant information about the scene as possible and collect physical evidence for further laboratory analyses. This approach is to ensure obtaining accurate factual data from a crime scene.
Why do police prevent witnesses from talking to each other?
The reason for preventing witnesses from talking to each other is not to let them affect one another’s impressions and perception of the crime. The less the witnesses interact, the greater the possibility is for the investigators to build an objective picture by comparing the witnesses’ testimonies. Next, the first responding officer is to protect the crime scene for inspection.

The Difference Between Crime Scene Reconstruction and Crime Scene Processing
When a crime occurs, experts are sent to the scene to collect and document all of the evidence. This includes things like blood, weapons, or fingerprints. Crime scene reconstruction is an analysis of the physical evidence and circumstances of a crime, theorizing how it occurred, and the scientific testing of that theory.
