What are the two types of sketches normally made of the crime scene?

The correct response is the distinction between rough and finished sketches, which is essential in crime scene documentation. A rough sketch is typically created on-site while the investigator is still at the scene, capturing the layout and relevant details quickly and without the need for precision. This sketch includes important features like the positions of evidence, bodies, and other critical observations that need to be documented immediately for later reference.

On the other hand, the finished sketch is a more refined version that is usually created after leaving the scene. It is drawn to scale, includes more precise measurements, and is often produced using drafting tools. This sketch serves as a formal representation of the crime scene that can be included in reports and presented in court. It captures the details more accurately and is meant for clarity and future reference.

These two types of sketches play a crucial role in ensuring that all critical information is documented thoroughly, contributing to the integrity and comprehensiveness of the investigation.
