A Guide for Explosion and Bombing Scene Investigation

Section D. Documenting the Scene
1. Develop Written Documentation
Principle: The investigator will prepare written scene documentation
to become part of the permanent record.
Procedure: The investigator should:
A. Document access to the scene (see the sample access control log
in appendix A).
B. Document activities, noting dates and times, associated with the
incident and the investigation (see the sample activity log in
appendix A).
C. Describe the overall scene in writing, noting physical and environmental
conditions (e.g., odors, weather, structural conditions)
(see the sample narrative description in appendix A).
D. Diagram and label scene features using sketches, floor plans, and
architectural or engineering drawings.
E. Describe and document the scene with measuring equipment,
which may include surveying equipment, GPS (global positioning
system) technology, or other available equipment.
Summary: Investigators must prepare written scene documentation
as part of the permanent record of the incident, which
will serve as the foundation for any incident reconstructions
and future proceedings.
2. Photograph/Videotape the Scene
Principle: The investigator must ensure that photographic documentation
is included in the permanent scene record.
This documentation should be completed prior to the
removal or disturbance of any items.
