The systematic exhumation of mass graves is becoming a frequent occurrence globally. Historically, it has been mostly anthropologists with their particular expertise in osteology that have been engaged by non-governmental organizations (NGO) to monitor mass grave exhumations and postmortem examinations, conducted by a host country or international forensic team, to ensure competence and a concern for justice. The excavation of graves and examination of their contents for the purposes of personal identification of victims and/or collection of evidence for prosecution require the creation of standards that meet international concerns for forensic investigation of the highest quality. However, many anthropologists are not experienced with large sites; do not have much, if any, expertise in archaeology; and are not equipped by training to assess the quality of a forensic pathologist's autopsy. This contribution is directed to both the NGO and the bio-archaeologist who are involved in the exhumation of mass graves. The experience and skills appropriate for the bio-archaeological monitor are outlined; similarly, the policies and standard operating procedures (SOP's) of the NGO that will enable the bio-archaeologist to perform their task are detailed. It is becoming increasingly clear that how a grave site was created, filled, and concealed, along with subsequent processes of site formation (e.g. slumping, robbing, animal scavenging and taphonomic alteration), require the expertise of a forensic archaeologist to discover and record site complexity along with associated forensic evidence. Similarly, the bodies themselves which are often skeletonized, fragmented and commingled pose challenges for the anthropologists and pathologists whose postmortem examinations must be critically evaluated. A model protocol for observations to make at the site as well as at the mortuary facility is provided to guide the monitor and to provide a structure for reports which are of standardized content suitable for international agencies concerned with mass grave investigation. © 2003 Elsevier Science Ireland Ltd.

Reliable identification of victims in mass graves is of humanitarian and human rights concern. Because mass graves in the former Yugoslavia usually contain an 'open' population of large numbers of unknown victims and therefore 'presumptive identifications' based on classical markers of identity are problematic, greater reliance is now made on blind matches between victim DNA and a database of donated blood DNA samples from family members of missing persons. Nevertheless, there will always remain a legal and social need to show good correspondence between a DNA-derived identification and classical markers of identity. Moreover, pathologists and anthropologists, who must continue to rely in much of their case work on classical methods, need to evaluate on an ongoing basis the goodness of fit between the two paradigms of identification. The Institute of Forensic Medicine and Laboratory for Anthropology in Belgrade participated in 2001 in the exhumation and identification of more than 300 bodies of Kosovar Albanians interred in two mass graves at Batajnica, near Belgrade, Serbia. Of these bodies, 136 were legally identified by the end of 2003 providing an opportunity for the forensic experts to evaluate their post-mortem findings of classical markers of identity. Sex and age at death of young to middle-aged adults were reliably determined but old adults were markedly under-aged. Stature was reconstructed reliably in 77% of cases. Dental status contributed little to identification efforts. In no case did classical markers of identity require rejection of the DNA-based identification. It is concluded that: sex determination from pelvic bones is very reliable, as are age at death estimates from pelvic and rib standards for young to middle-aged adults but that uncertainty intervals for age at death in older adults be broadened or refined by creation of local osteological standards. © 2007 Elsevier Ireland Ltd.

With the exception of exhumations of mass graves in Latin America, forensic dentists and odontologists are rarely involved in the examination of mortal remains recovered from mass graves. The cited reason is often that " there are no dental records-so what is the point"? In this presentation we review the published accounts of examination of remains arising from the conflict in the former Yugoslavia between 1991 and 1999 in which dental examinations are reported. There are roughly 30,000 missing persons of which more than 15,000 mortal remains have been identified, mostly based on DNA. There are 9 sources which describe postmortem dental examinations of 3919 sets of remains; of these, 23% were purported to have been identified specifically from dental information. Of the 8100 listed missing persons from the Srebrenica mass killings in 1995, we located 600 dental records. A sample of 263 charts was examined for information about first molar treatment as we are concerned that dental charting of individuals who lose their first molars may be incorrectly done if allowance is not made for mesial drift of the remaining molars. We found that of all the first molar extractions that are ever going to occur according to these dental charts, 63% have taken place by age 18. The majority of extracted first molars have a functional age of 17 years. We observe that an adult's remains from Srebrenica usually have only second and third molars, which have often drifted forward to occupy the position of the first molar creating the appearance of third molar agenesis. We conclude: that, since dental identifications of victims in mass graves and mass disasters is the exception rather than the rule, even in the absence of DNA-based identifications, international forensic odontologists have an ethical obligation to become more involved in examination of mass grave victims, that there must be more determined searches for antemortem dental records; that local dentists should be approached to participate in the examination of remains and lastly that dental examination and charting by anthropologists and pathologists may be grossly inaccurate. Furthermore, even in the absence of dental records, there is significant information about the individual to be obtained by an oral biologist since many families have useful memories about the oral status of their loved ones who went missing. © 2010 Elsevier Ireland Ltd.
