Which of the following should be included in a sketch of a crime scene?

A sketch of a crime scene serves as a visual representation of the area where the incident took place and is crucial for documenting evidence and the scene layout. Including accurate measurements allows for a precise depiction of the distances and locations of various elements within the scene, which can be vital for later investigations and court presentations. An indicator showing north is also essential because it helps orient the sketch in relation to the geographic layout of the area, ensuring that anyone reviewing the sketch can understand the spatial relationships and directions relevant to the scene.

Incorporating these elements into the sketch enhances its utility as a piece of evidence, providing clarity and context that can support the overall investigation. While other options may contain useful information, they are not foundational elements of a crime scene sketch.

For example, focusing solely on major evidence does not give a full picture of the scene, and a detailed narrative, while valuable, is more suited for a report than a visual sketch. Personal notes from police officers might contain insights, but they are not part of an official sketch. Thus, including accurate measurements and a north indicator is essential for creating a reliable and informative crime scene sketch.
