What is the first step to take at a crime scene?

The first step to take at a crime scene is to secure the scene. Securing the scene ensures that the area is protected from contamination and that any potential evidence remains undisturbed. This crucial step allows investigators to maintain the integrity of the scene, which is vital for collecting reliable evidence and ensuring that the investigation can move forward effectively.

By securing the scene, law enforcement can control access, preserve potential evidence, and gather initial information later in a structured manner, such as interviewing witnesses or conducting further analysis. Without first securing the scene, any other actions taken might compromise the evidence, leading to difficulties in the investigation.
