When must evidence be photographed?

When must evidence be photographed?

• A. After you complete a full scene walkthrough.
• B. After you have documented a preliminary sketch.
• C. After evidence collection begins.
• D. Before any evidence is collected.

Answer: (D)

Photographing evidence before touching or moving anything preserves the original state of the scene. It captures exactly how items were found, including their location, orientation, and condition, which provides a reliable baseline for later analysis and reconstruction. If you wait to photograph after you’ve started handling evidence, you risk disturbing the scene, altering relationships between items, and contaminating the context, all of which can undermine the integrity and usefulness of the evidence. In practice, you would take comprehensive photos before any collection—wide shots to show the overall scene, medium shots for context, and close-ups of specific items with a scale or ruler—then proceed to collect the evidence. This order helps maintain a clear chain of custody and a dependable record for investigation and potential court use.
