What is the first step when approaching a crime scene?

The correct first step when approaching a crime scene is to secure the scene. This is crucial to ensure that the area is preserved for forensic examination and that evidence remains uncontaminated. By securing the scene, investigators can control access, preventing unauthorized individuals from entering and potentially altering or destroying evidence. This step also includes establishing a perimeter and ensuring that no one enters the area until it has been properly documented and investigated.

While interviewing witnesses, calling for backup, and documenting surroundings are important components of the investigative process, they should occur after the scene is secured. Immediately securing the scene lays the groundwork for a thorough and effective investigation, as it upholds the integrity of the evidence collected and the overall reliability of the findings during the investigation process.
