What is NOT a method of documentation in forensic investigations?

In forensic investigations, documentation is crucial for preserving evidence and providing a clear record of the crime scene. Note-taking, photography, and videography are all key methods used by investigators to document details of the scene, witness statements, and other relevant information. Each of these techniques allows for a comprehensive capturing of the evidence as it is found.

Autopsy, on the other hand, serves a different purpose. It is a medical examination of a deceased individual to determine the cause of death, but it is not a method of documenting a crime scene. Instead, it falls under the scope of post-mortem examination rather than the immediate documentation of forensic evidence. Thus, while autopsies are vital within the context of forensic investigations, they do not constitute a method of documenting crime scenes as other options do. Forensic documentation focuses on capturing the scene and evidence before it is altered or removed, which is not the primary role of an autopsy.
