What is the primary duty of the first responder at a crime scene?

The primary duty of the first responder at a crime scene is to assess hazards and protect evidence. This role is crucial as the first responder is often the first individual on the scene and is responsible for ensuring the safety of everyone present, including victims, witnesses, and their own safety. By identifying and managing any potential hazards—such as unstable structures, hazardous materials, or violent situations—the first responder can create a safe environment that allows for further investigation without the risk of injury.

In addition to safety, the first responder must also take steps to secure and protect the crime scene. This includes preventing contamination or loss of evidence, which is vital for the integrity of the investigation that follows. Safeguarding evidence helps preserve any potential clues that may assist in solving the crime, ensuring that they can be collected later by investigators in a manner that adheres to legal standards.

The other roles mentioned, such as investigating the crime, collecting evidence, and interviewing witnesses, are typically undertakings for specialized investigators or detectives once the scene is secured and deemed safe. These responsibilities can only be effectively performed once the first responder has ensured the area is clear of hazards and protected potential evidence.
