Which practice preserves and documents evidence at a scene?

• A. Secure the scene
• B. Maintain chain of custody
• C. Photograph and log locations
• D. Restrict access

Answer: (B)

Maintaining chain of custody is the process that ensures evidence is preserved in its original state and that every transfer of custody is documented. At a scene, it means labeling items, sealing them in proper containers, and recording who collected them, when, and how they were stored or transported. This creates an unbroken, verifiable trail from discovery to presentation in court, protecting the evidence’s integrity and its admissibility. While securing the scene, restricting access, and photographing or logging locations help prevent contamination and document the scene, the formal chain of custody specifically tracks the handling of the evidence itself and ensures there is a clear, auditable record of everyone who touched it and when.
