Geophysical surveys are used in forensic investigations for searching buried metallic and non-metallic objects and mapping disturbances on the ground due to excavations related to civil and political criminal activities and murder cases. Geophysics is also utilized for investigating environmental crimes related to illegal dump of dangerous materials such as industrial chemicals, construction debris and pollutants in to the subsurface and groundwater.
Geophysical methods are very appealing to forensic investigators since these techniques have limited to no-contact with the evidence at all and are non-invasive or destructive. The surveys can easily be deployed in the field over large areas for a quick discrimination between pristine and altered zones where the suspect may have made the illegal burial or disposal.
Several geophysical techniques and search methodologies are used for detecting shallow buried metallic and non-metallic objects, guns, knifes, drums, barrels, canisters, burials, cadavers and human remains, money coffers and caletas, drug packages, excavations, tunnels and reinforced concrete bunkers.
