Many law enforcement agencies use a variety of preprinted documents or forms, designed to record certain aspects of crime scene investigation. These documents normally have resulted from a trial-and-error approach based on actual case experiences. Despite variations in the design of these documents, the purpose and goals behind their use are usually identical from one agency to another.
There is an important point to consider when forms, are being drafted for routine use. Often, there is a tendency to regard forms as means to cover every possibility that personnel may confront, such documents normally serve only as reminders of the minimum pertinent information needed to perform a task. Each scene will require some level of deviation from the norm, based on the complexities at hand. Forms are not substitutes for thinking; they are merely tools to assist personnel to fully exercise training and experience to meet the needs of a given situation.
There are normally six important categories of documentation that are considered applicable to any search:
Documentation of major events, times and movements relating to the search efforts; documentation of initial and continuing management and administrative steps which are taken to insure that an organized search is accomplished.
Documentation of the general appearance of the scene as first observed; extreme detail regarding evidence or actual collection of evidence, is normally beyond the scope of the Narrative Description
Documentation of the process of scene photography which records the overall, medium, and close-up views of the scene; a log is produced representing the technical and descriptive information concerning the photographic task.
Documentation of physical evidence locations, as well as measurements showing pertinent size and distance relationships in the crime scene area.
Documentation of the recognition, collection, marking, and packaging of physical evidence for administrative and chain of custody purposes.
Documentation of the recognition, collection, marking, and packaging of lifts made of latent prints discovered at the scene.
