Securing the Scene

The scene boundaries are established by identifying the focal point of the scene and extending outward. Any type of physical barrier can be used to section off the area.

A log of all persons who had access to the scene should be maintained. This will provide important information for evaluating the need for elimination samples from those persons.

Crime scene documentation is an important resource for the evaluation of the integrity and condition of the evidence.
