What are the two main categories of sketches in crime scene investigation?

In crime scene investigation, sketches serve as critical tools to document the scene and provide a visual representation of the layout and important evidence. The primary categories of sketches are rough sketches and finished sketches.

Rough sketches are typically drawn at the crime scene and include the basic layout, dimensions, and locations of evidence. They focus on capturing the immediate details quickly and accurately, often including measurements and other relevant notes. This type of sketch allows investigators to record information that might otherwise be forgotten or overlooked.

Finished sketches, on the other hand, are more polished and precise representations of the crime scene. They are usually created after the investigation has concluded and are often produced using computer software or more refined drawing techniques. Finished sketches are intended for presentation in court or to provide comprehensive documentation of the scene, displaying all relevant details in a clear and professional manner.

The other choices, while they include terms that might be relevant in different contexts, do not accurately reflect the standard classifications used in crime scene documentation. The distinction between rough and finished sketches is critical for ensuring that the interpretation and use of visual evidence in investigations are effective and clear.
