What does a rough crime scene sketch typically include?

A rough crime scene sketch typically includes all measurements because it serves as a preliminary representation of the scene, capturing the layout and positions of important elements in relation to one another. This sketch is essential for documenting the dimensions of the crime scene, which can be critical for legal and investigative purposes. Measurements provide context and help recreate the scene, allowing investigators to analyze physical evidence effectively later on.

In contrast, while color-coded evidence markers, witness statements, and police officer signatures may be relevant to the overall investigation and documentation process, they are not standard features found in a rough crime scene sketch. Those elements are usually part of more detailed reports and notes that accompany the sketch or appear in final evidence presentations. Therefore, focusing on measurements as the primary content in a rough sketch is crucial for accurately portraying the scene and its relative elements.
