Why are both rough and final sketches used?

• A. Rough sketches are used at the scene for layout; final sketches are used in court
• B. Rough sketches are for notes; final sketches are not used in court
• C. Rough sketches replace photographs; final sketches are unnecessary
• D. Rough sketches are not kept as part of the record

Answer: (B)

Two sketches serve different stages of documenting a scene. A rough sketch is created on the scene to quickly capture the layout, relative positions, and relationships between objects while measurements and notes are still being gathered. It’s flexible and fast, guiding what to photograph, what to measure, and what features need closer attention. The final sketch comes later, after precise measurements are obtained, and is drawn to scale with proper orientation and a legend. This cleaned, formal drawing provides an accurate, reproducible representation that can be used in reports and in court. Keeping both ensures investigators have an immediate, memory-friendly diagram from the scene and a polished, authoritative depiction for the record and the legal process.
