Who should be fingerprint conscious at a crime scene?

• A. Patrol supervisor
• B. First officer at a crime scene
• C. CSI technician
• D. Detective

Answer: (B)

The key idea is that preservation of fingerprints starts with the first responder. When a crime scene is cold, the actions of the initial officer set the stage for whether prints remain intact. The first officer at the scene is responsible for securing the area, limiting access, and avoiding unnecessary contact with surfaces that could bear prints. This prevents contamination or accidental smudging of latent prints, which is crucial because later specialists rely on clear, intact prints to lift and photograph evidence. While a CSI technician will process prints and a detective will analyze findings later, those steps depend on the scene having been kept as uncontaminated as possible from the moment of arrival. A patrol supervisor oversees the operation and may guide the response, but the practical duty of maintaining print integrity from the outset falls to the first officer who enters.
