What is the first thing a forensic scientist does at a crime scene?

Forensic scientists in the USA follow a strict protocol when arriving at a crime scene. The first crucial step is to secure the area to preserve evidence. Next, they assess the scene and make detailed observations. This may include documenting the surroundings, taking photographs, and creating sketches. After these initial steps, forensic scientists collect evidence such as fingerprints, bodily fluids, or DNA samples. This meticulous approach ensures that no evidence is overlooked and that the integrity of the crime scene is maintained, allowing for a thorough investigation.
