Which step is important in preparing a crime scene sketch?

Making a rough drawing on paper is a crucial step in preparing a crime scene sketch because it allows investigators to capture the layout and details of the scene accurately before creating a more formalized version. This rough sketch serves as the foundation for the final sketch, helping to ensure that important elements, such as the position of evidence, the physical layout, and scale, are preserved. The initial sketch can be done quickly and on the spot, which is vital in a rapidly changing environment where the scene may be disturbed before a thorough analysis can be completed.

This step provides a foundational record of the scene that can later be referenced when creating a more precise representation, ensuring that all relevant information is taken into account and accurately depicted.
