What is the initial action to secure a crime scene?

• A. Set up a perimeter for the scene (mark it off)
• B. Call for media to arrive
• C. Search the area immediately
• D. Collect all evidence at once

Answer: (A)

Setting up a perimeter around the scene is the first essential step to preserve evidence and maintain the investigation’s integrity. By marking off the area, you control access, prevent contamination, and create a defined space for documenting what’s there. This boundary helps responders work methodically, protects people’s safety, and establishes a clear timeline of who enters and exits, which is crucial for the chain of custody. Other actions undermine this foundation. Bringing in media can create safety risks and reveal sensitive information. Trying to search the area before securing the scene risks destroying or altering evidence and biasing the investigation. Attempting to collect all evidence at once ignores proper procedures for documentation, packaging, and labeling. The perimeter sets the stage for careful, systematic processing of the scene.
