If you must enter the crime scene to render aid, which rule about handling evidence applies?

• A. Do not rearrange or move anything
• B. Photograph the area after moving items
• C. Do not preserve the scene
• D. Check the patient for injuries

Answer: (A)

When you enter a crime scene to render aid, the crucial rule is to avoid rearranging or moving anything. Disturbing objects can change or contaminate evidence—fingerprints, DNA, tool marks, the position of items, and the overall scene layout—which can mislead investigators and compromise the investigation. The goal is to provide medical help while keeping the scene as undisturbed as possible. If you must access the patient, minimize what you touch and notify law enforcement immediately so they can advise or take over any necessary movement. If movement is truly unavoidable, document exactly what you touched or moved and why, so the scene can be reconstructed later. Preserving the scene is essential, and while you should assess and treat the patient, moving objects to aid the patient is not the preferred practice.
