The investigation of a bomb scene involves a systematic crime scene search to discover, identify, collect, and preserve evidence of the bombing.
Abstract
Immediately after arrival of public safety personnel, investigators must conduct a quick search of the area to determine the presence of additional incendiary devices. Rendering first aid to the injured is the second priority. Attention is then turned to containment of the crime scene and evidence preservation. This is accomplished by roping off the perimeter of the adjacent areas of the blast site. Photographs and sketches should be made before the actual investigation begins, and the search itself is conducted in a carefully planned, systematic manner. A 'grid pattern' search of the area is recommended. As each item of evidence (e.g., debris from the device) is located, it should be photographed in place prior to collection and marked. Equipment which is used in the bomb scene search includes rope or tape, shovels, brooms, portable lighting fixtures, and sifting screens. Specialized techniques, such as those used by forensic chemists, should be employed for major bombing incidents. In major incidents, the investigator should assume a supervisory function, delegating search responsibilities to others. A five-entry bibliography is included.
