What is the primary purpose of using scene markers at a crime scene?

The primary purpose of using scene markers at a crime scene is to indicate the position of evidence for later analysis. Scene markers play a crucial role in preserving the integrity of the crime scene by clearly marking the location of physical evidence as it was found. This allows investigators to document the scene accurately, ensuring that the evidence can be located and analyzed later, which is essential for building a strong case in criminal investigations. By marking the evidence, investigators can maintain a chain of custody, preventing contamination or loss of crucial information that may be pivotal in understanding the events that occurred.

Markers also assist in the overall reconstruction of the crime scene during court proceedings, allowing jurors to visualize the layout and context in which the crime took place. The effectiveness of the investigation heavily relies on the proper documentation and handling of evidence, making scene markers a vital tool for forensic professionals.
