What is the proper approach to handling evidence at a scene?

• A. Secure and preserve the scene, prevent contamination, document handling steps, and maintain chain of custody.
• B. Move evidence to a different location for convenience.
• C. Allow witnesses to handle evidence without supervision.
• D. Photograph evidence but avoid logging handling steps.

Answer: (A)

Handling evidence at a scene centers on preserving its integrity from the moment it’s found to its presentation in court. The proper approach is to secure and preserve the scene, prevent contamination, document every handling step, and maintain the chain of custody. Securing the scene prevents changes and tampering, preserving contamination means the evidence stays in the condition it was found in, documenting handling steps creates a clear record of what was done and by whom, and maintaining chain of custody provides a continuous, verifiable trail that supports admissibility in legal proceedings. Moving evidence for convenience can alter or destroy its original state and breaks the chain of custody. Letting witnesses handle evidence without supervision risks contamination or misinterpretation. Photographing evidence without logging handling steps fails to establish who touched it and when, undermining trust in the evidence.
