Forensic anthropology and the most probable cause of death in cases of violations against international humanitarian law: an example from Bosnia and Herzegovina

This study presents the results of the analysis of at least 298 predominantly male individuals, between 15 and 75 years, who were recovered from an open cast mine in Bosnia-Herzegovina. Particular attention is paid to identifying the mechanisms of injury and determination of the most probable cause of death based on the assessment of lethal or lethal-if-untreated injuries recorded in the skeleton. It was calculated that at least 38.9% (155/398) of individuals sustained gunshot wounds (GSWs) (plus one shrapnel wound) and may have died as consequence of these injuries. Among individuals who died from GSWs, there were 142 males (91.60%), eight females (5.1%) and five cases that were (3.2%) undetermined. One male individual sustained shrapnel injuries. This study presents an example of the multidisciplinary approach to the effective forensic investigation of violation against International Humanitarian Law, as well as an example of how it is possible to obtain meaningful results to assist the needs of the prosecution in these kind of cases despite the large number of cases and technological constraints.     

Issues in the global applications of methodology in forensic anthropology

The project and research reported in this collection of articles follows a long-term historical pattern in forensic anthropology in which new case work and applications reveal methodological issues that need to be addressed. Forensic anthropological analysis in the area of the former Yugoslavia led to questions raised regarding the applicability of methods developed from samples in other regions. The subsequently organized project reveals that such differences exist and new methodology and data are presented to facilitate applications in the Balkan area. The effort illustrates how case applications and court testimony can stimulate research advances. The articles also serve as a model for the improvement of methodology available for global applications.

A standard procedure for accommodating forensic anthropological and genetic analysis of decomposing human remains from tropical climates

At the Medical Legal Center in Ribeirão Preto, Brazil (CEMEL/FMRP-USP), unidentified decomposing bodies routinely undergo soft tissue removal (by immersion in water at 80–90 °C for 24 h) prior to an anthropological analysis intended to yield a biological profile of age, sex, ancestry, height, pathology and so on. In the event that this analysis is unsuccessful, samples may be submitted for DNA profiling. The tropical climate and the defleshing process may confound preservation, recovery and analysis of DNA, however. In order to establish an optimal standardized protocol for identification of decomposing human remains from a tropical climatic region, the outcome of anthropological and genetic analyses was compared, along with the utility of bone (mainly femur and sternum) and teeth (mainly molar) specimens for DNA analysis. In a sample (n = 39) of partially skeletonized remains, anthropological analysis was sufficient for identification in eight cases. In further six cases, DNA profiling was successfully attempted. As a consequence of our study, we recommend collection of 1–2 well preserved teeth prior to defleshing and anthropological analysis in these circumstances.     

Preliminary results of an investigation on postmortem variations in human skeletal mass of buried bones

Extreme fragmentation can complicate the inventory of human skeletal remains. In such cases, skeletal mass can provide information regarding skeleton completeness and the minimum number of individuals. For that purpose, several references for skeletal mass can be used to establish comparisons and draw inferences regarding those parameters. However, little is known about the feasibility of establishing comparisons between inherently different materials, as is the case of curated reference skeletal collections and human remains recovered from forensic and archaeological settings. The objective of this paper was to investigate the effect of inhumation, weather and heat exposure on the skeletal mass of two different bone types. This was investigated on a sample of 30 human bone fragments (14 trabecular bones and 16 compact bones) that was experimentally buried for two years after being submitted to one of four different heat treatments (left unburned; 500?°C; 900?°C; 1000?°C). Bones were exhumed periodically to assess time-related mass variation. Skeletal mass varied substantially, decreasing and increasing in accordance to the interchanging dry and wet seasons. However, trends were not the same for the two bone types and the four temperature thresholds. The reason for this appears to be related to water absorption and to the differential heat-induced changes in bone microporosity, volume, and composition. Our results suggest that mass comparisons against published references should be performed only after the skeletal remains have been preemptively dried from exogenous water.

Sampling and statistical considerations for the Suchey–Brooks method for pubic bone age estimation: Implications for regional comparisons

Although the Suchey–Brooks (SB) system is currently the most widely used method for age-at-death estimation from the pubic bone, the system continues to evolve through stepwise improvements. Since the system was developed from a pubic bone sample derived mainly from North Americans, it is unclear how well it performs on populations from other continents. During the last decade, studies of the SB system on pubic bone samples from local populations in Europe and Asia have indicated regional differences in the relationship between age and pubic bone development. However, these studies have for the most part followed different research protocols, which make comparisons between their results less meaningful. It would be most useful if future regional analysis of the SB system were done in a rigorous and uniform fashion, following standard procedures. In this paper, sampling and statistical considerations are outlined that hopefully will help to standardize research on the SB system.     

Evaluation of Stature Estimation from the Database for Forensic Anthropology*†

Abstract: Trotter and Gleser’s ( 1 - 3 ) stature equations, conventionally used to estimate stature, are not appropriate to use in the modern forensic context. In this study, stature is assessed with a modern (birth years after 1944) American sample (N = 242) derived from the National Institute of Justice Database for Forensic Anthropology in the United States and the Forensic Anthropology Databank. New stature formulae have been calculated using forensic stature (FSTAT) and a combined dataset of forensic, cadaver, and measured statures referred to as Any Stature (ASTAT). The new FSTAT‐based equations had an improved accuracy in Blacks with little improvement over Ousley’s ( 4 ) equations for Whites. ASTAT‐based equations performed equal to those of FSTAT equations and may be more appropriate, because they reflect both the variation in reported statures and in cadaver statures. It is essential to use not only equations based on forensic statures, but also equations based on modern samples.     

Virtual autopsy and forensic anthropology of a mummified fetus: a report of one case

A jar containing the mummified body of a fetus was found in a bush near a building. Full-body multislice computed tomography (MSCT) was performed prior to autopsy to study the bones and internal organs. Age was estimated by measuring femoral and tibial lengths and examining the temporal and occipital bones. The results were then compared with the autopsy and histopathological findings. MSCT was superior to autopsy for examination of the bones and internal organs. Autopsy was difficult because of the fragility of the dried corpse. MSCT determined the gestational age of the fetus and excluded skeletal abnormalities. Estimated age was similar with the two methods used. However, the major advantage of MSCT was rapid measurement of bones or anatomical regions which are difficult to examine during autopsy and which required specific preparation for further anthropological study. This case report illustrates the possibilities offered by MSCT for studying mummified bodies, even fetuses.     

Use of the global positioning system in the field recovery of scattered human remains

This study examines the Global Positioning System (GPS) as a tool for field mapping of scattered human remains or other materials in forensic investigations. Two aspects of the GPS are considered: (1) the level of accuracy that can be obtained using a mid-priced GPS unit, and (2) the effectiveness of using the GPS to map scattered materials. The positional accuracy of the GPS receiver was tested using a National Geodetic Survey (NGS) point located in Baton Rouge, LA. The utility of the GPS for mapping was investigated by setting up a mock field recovery and mapping the remains using both the GPS and traditional archeological methods. The results indicate that the positional error for a single location using GPS was less than one-half meter. However, when multiple positions were considered, the data produced on different days were not consistent. Further, the GPS receiver used in this study could not distinguish items in close association. Factors such as tree cover density, the proximity of the materials to structures or trees, and satellite positioning contributed to the erratic data. These results indicate that traditional techniques and photographs are still indispensable for mapping scattered remains or artifacts.     

Mental health legislation and human rights in England, Wales and the Republic of Ireland

In 2005, the World Health Organization (WHO) published its Resource Book on Mental Health, Human Rights and Legislation (Geneva: WHO) presenting a detailed statement of human rights issues which need to be addressed in national legislation relating to mental health. The purpose of this paper is to determine the extent to which revised mental health legislation in England, Wales (2007) and Ireland (2001) accords with these standards (excluding standards relating solely to children or mentally-ill offenders).Legislation in England and Wales meets 90 (54.2%) of the 166 WHO standards examined, while legislation in Ireland meets 80 standards (48.2%). Areas of high compliance include definitions of mental disorder, relatively robust procedures for involuntary admission and treatment (although provision of information remains suboptimal) and clarity regarding offences and penalties Areas of medium compliance relate to competence, capacity and consent (with a particular deficit in capacity legislation in Ireland), oversight and review (which exclude long-term voluntary patients and require more robust complaints procedures), and rules governing special treatments, seclusion and restraint. Areas of low compliance relate to promoting rights (impacting on other areas within legislation, such as information management), voluntary patients (especially non-protesting, incapacitated patients), protection of vulnerable groups and emergency treatment. The greatest single deficit in both jurisdictions relates to economic and social rights.There are four key areas in need of rectification and clarification in relation to mental health legislation in England, Wales and Ireland; these relate to (1) measures to protect and promote the rights of voluntary patients; (2) issues relating to competence, capacity and consent (especially in Ireland); (3) the role of “common law” in relation to mental health law (especially in England and Wales); and (4) the extent to which each jurisdiction wishes to protect the economic and social rights of the mentally ill through mental health legislation rather than general legislation.It is hoped that this preliminary analysis of mental health legislation will prompt deeper national audits of mental health and general law as it relates to the mentally ill, performed by multi-disciplinary committees, as recommended by the WHO.
