What is the purpose of a crime scene sketch?

• A. To establish guilt of suspects.
• B. To document relationships and locations of evidence for investigation and court.
• C. To replace witness interviews.
• D. To serve as a legal record of the arrest.

Answer: (B)

A crime scene sketch serves to document the relationships and locations of evidence for investigation and court. It creates a visual map of how items are positioned, showing distances and spatial relationships so investigators can reconstruct what happened and why certain items matter. This helps the team locate evidence during searches, compare with photographs, and present a clear, understandable view to a judge and jury. A good sketch is often drawn to scale and includes a north arrow, a legend, labeled points, and details like date, time, and who prepared it, making it a reliable part of the investigative record.

It isn’t about establishing guilt, replacing witness interviews, or serving as the arrest record. Those roles belong to evidence and testimony, interviews, and official arrest documentation.
