What is the first step in crime scene documentation?

Taking notes serves as the foundational step in crime scene documentation because it allows investigators to record the initial observations and condition of the scene as soon as they arrive. These notes include vital information such as the time of arrival, the environmental conditions, and immediate impressions of the scene, which can guide further investigation.

Noted observations at this stage inform subsequent processes like photography and sketching, which rely on precise information about the context and layout of the crime scene. Additionally, this documentation ensures that the notes can serve as a reference during the investigation and in court, helping to maintain a clear and accurate narrative of the events surrounding the crime. By effectively capturing these details early on, investigators lay the groundwork for a thorough and organized approach to evidence collection and analysis.
