ABSTRACT
Applying geophysical methods to locate physical evidence is by no means the ultimate panacea for the criminal investigator. Geophysical methods are based on detecting and measuring physical, electrical, and chemical contrasts within the earth. Contrasts between the physical evidence being sought and the materials within the earth may be very small and require the use of sensitive equipment to detect. The success of a geophysical investigation is a function of numerous factors including site conditions, the physical characteristics of the evidence being sought, and the experience of the individuals conducting the geophysical surveys.
