Abstract
The purpose of a diagram/sketch is for the investigator to record pertinent details or items pertaining to the case. The diagram/sketch should show location of details in a room as well as measurements. Sketches can be rough and finished, or smooth. The artist should include whatever the investigator deems important, such as potential entrances and exits, location of bodies, furnishings, burn patterns, point of origin, and location of spalling. Two persons should make the measurements with a tape. Sketches can be two- or three-dimensional. The legend is a guide and form of identification for the diagram/sketch, and includes all important information such as the case number, time of the fire, meaning of symbols, names of investigatory assistants, and scale data. Two footnotes, seven examples, and a nine-item bibliography are included.
