Which statement best describes the purpose of a rough sketch?

• A. It is drawn to scale
• B. It replaces photographs
• C. It shows the general layout and approximate locations of evidence
• D. It is used only for courtroom demonstrations

Answer: (C)

Rough sketches are meant to capture the scene's spatial relationships quickly. They illustrate the general layout of the area and the approximate locations of evidence, so investigators can visualize how things relate to one another and plan follow-up steps. Since it's a rough draft, it isn't drawn to scale and measurements aren’t precise; accuracy can come later in more detailed, scaled diagrams or in the accompanying measurement data. Photographs complement sketches by providing exact visuals of the evidence and conditions, not by replacing the rough sketch. Rough sketches are practical tools during the investigation, not just for courtroom demonstrations. So the purpose described is that it shows the general layout and approximate locations of evidence.
