What method is commonly used to document the position of evidence at a crime scene?

Sketching is a commonly used method for documenting the position of evidence at a crime scene because it provides a clear visual representation of how evidence is placed in relation to other objects and landmarks within the scene. This method allows investigators to include important details such as measurements, the scale of the area, and specific features that may not be easily captured in photographs.

A sketch can depict the overall layout of the crime scene, helping to recreate the scenario during investigations and trials. It serves not only as a visual aid but also as a written record, including critical information like the date, time, and the names of the individuals who created the sketch. Sketching is instrumental in preserving the scene's context, which can be vital for understanding the sequence of events or actions taken.

While other methods like photographing or creating 3D models can also be useful, they often serve as supplementary documentation rather than providing the comprehensive spatial understanding that a well-done sketch achieves.
