The use of geoscience methods for terrestrial forensic searches

The rapidly expanding field of forensic geoscience derives its roots from nineteenth- and early twentieth-century scientists who both influence and are influenced by literature and fictional writing. Forensic geoscience borrows much, but not all, of its precepts from geological and geomorphological analytical techniques. Fundamental differences exist between forensic geoscience and its sister disciplines, fundamental enough to make the unwary geoscientist succumb to philosophical and practical pitfalls which will not only endanger the outline of their report, but may well indeed provide false-negative or false-positive results leading to contrary or inaccurate conclusions. In the law, such outcomes have devastating and untenable consequences. Forensic geoscience requires techniques of exclusion rather than inclusion and an acknowledgement that analytical techniques may be diagnostic only in very specific situations. Whether analysis of the ubiquitous or the exotic component is chosen, acknowledgement of the need for samples to be representative is required. The presentation of false-positive results or the lack of identification of sample 'mixing' is prerequisite to the application of statistical tests which must be applied in the most careful manner. The realization of the limitations of the technique requires, wherever possible, conjunctive analysis by other truly independent techniques. While personal opinion derives from experience, there is no place for assumption. Research papers in forensic geoscience are not submitted to be speculative or challenging as may be the case in many fields of geomorphology and geology. There is no place for conjecture in forensic geoscience.

Necropolitics: Mass Graves and Exhumations in the Age of Human Rights

Electrical resistivity survey to search for a recent clandestine burial of a homicide victim, UK

This paper will provide mass fatality emergency planners, police, medical examiners, coroners and other Disaster Victim Identification (DVI) personnel ways to integrate forensic anthropologists into DVI operations and demonstrate how anthropological contributions have improved DVI projects. In mass disaster situations, anthropologists have traditionally been limited to developing biological profiles from skeletal remains. Over the past decade, however, anthropologists' involvement in DVI has extended well beyond this traditional role as they have taken on increasingly diverse tasks and responsibilities. Anthropological involvement in DVI operations is often dictated by an incident's specific characteristics, particularly events involving extensive fragmentation, commingling, or other forms of compromised remains. This paper will provide examples from recent DVI incidents to illustrate the operational utility of anthropologists in the DVI context. The points where it is most beneficial to integrate anthropologists into the DVI process include: (1) during recovery at the disaster scene; (2) at the triage station as remains are brought into the mortuary; and (3) in conducting the reconciliation process. Particular attention will be paid to quality control and quality assurance measures anthropologists have developed and implemented for DVI projects. Overall, this paper will explain how anthropological expertise can be used to increase accuracy in DVI while reducing the project's cost and duration.
