What is the first step a Crime Scene Analyst should take upon arriving at a crime scene?

The first step a Crime Scene Analyst should take upon arriving at a crime scene is to secure the scene to ensure that evidence is not contaminated or disturbed. Securing the scene establishes the integrity of the scene, allowing for proper collection and analysis of evidence later on. This step is critical as it protects the area from unauthorized individuals who may inadvertently alter evidence or tamper with the scene.

By preventing contamination and preserving the original state of the scene, the analyst facilitates a thorough and accurate examination. Once the scene is secured, investigators can safely document, gather evidence, and interview witnesses, knowing that the integrity of the crime scene has been maintained.

This protocol forms the foundation of effective crime scene management and is essential for ensuring that the evidence collected can withstand scrutiny in a court of law, thereby supporting the investigation's overall integrity.
