Investigator notes do what? (Why do we take them, what purpose do they serve?) Notes of the investigator are utilized for the purpose of documentation. Notes of an investigator ought to be in chronological order. This helps in determining the events’ chain. All notes need to be descriptive in a high manner to support in cases (Crime scene investigation, 2000). True or False: Your notes are your observations of the scene and are a log of what you did within the scene including investigative theories explored. Why or why not? One’s notes are not his/her observations of the act and aren’t a record of what was done by the person in the scene consisting of the explored theories of investigation. Notes ought to be facts relating to the scene of the crime. Any sort of opinions, conclusions, or analyses must not be present in the notes (Crime scene investigation, 2000).
