Which step involves Prepare Sketch / Diagram?

• A. Prepare Sketch / Diagram
• B. Photograph Scene
• C. Narrative Description
• D. Record and Collect Evidence

Answer: (A)

Sketching a scene is the step that translates the messy, real-world layout into a clear, scaled map showing where each item is located and how they relate to fixed references in the space. This diagram includes measurements, a scale, a north arrow, and labels for each piece of evidence, making distances and spatial relationships easy to understand at a glance. Photographs capture details visually but can miss exact spatial relationships and scale; narrative descriptions convey events and context but not precise layout; recording and collecting evidence focuses on preserving items for analysis and the chain of custody. Because the diagrammatic representation is the dedicated way to communicate the scene’s geometry and relationships, this step is the one that involves preparing a sketch or diagram.
