How should photographs and diagrams be used in the investigation?

• A. They replace written statements.
• B. They are optional and rarely used.
• C. They document the scene, help visualize relationships and trajectories, and support later analysis and reporting.
• D. They provide entertainment for investigators.

Answer: (C)

Photographs and diagrams are visual records that capture the scene as it was found, providing an objective basis for understanding what happened. They document positions, conditions, and relationships between evidence pieces, which written notes alone can’t fully convey. Diagrams translate that information into a clear spatial representation—showing where items are, how they relate to one another, and any trajectories or angles involved. Together, they support later analysis, reconstruction of the sequence of events, and the final report by giving investigators a verifiable, shareable reference. They should complement written statements, not replace them, and must be collected with proper standards and labeling. They are not merely optional or for entertainment.
