Medicolegal anthropology in France.

Medicolegal anthropology has a very long history in France. Basic studies on human skeletal remains started as early as the 18th century. The 19th century produced many medical theses and research papers on age, sex, as well as stature estimation. The research proliferated in the first 60 years of the 20th century, much of which is still in use in France and abroad. The later half of the 20th century, however, was dormant in research on human skeletal biology at a time when forensic anthropology was becoming an active field worldwide. In the last decade, medicolegal anthropology took a different perspective, independent of its traditional roots. Research and practice have both been in the professional domain of forensic physicians unlike the situation in many other countries. Population based studies requiring large databases or skeletal collections have diminished considerably. Thus, most research has been on factors of individualization such as trauma, time since death, crime scene investigation, and facial reconstruction. It is suggested that there is a need for cooperation between the forensic physician and anthropologist to further research. This also encourages anthropologists to carry out research and practice that can fulfill the needs of the medicolegal system of the country.     

Forensic anthropology in Latin America

Forensic anthropology has been one of the fastest growing medico-legal disciplines both in its contribution to the practical needs of the legal system and research accomplishments. New anthropological standards were developed to apply to a specific population of a region. The purpose of this paper is to analyze a large sample of anthropological forensic cases and to review pertinent literature that deals with anthropological standards developed for the population of the continent of Central and South America. Using Uruguay as an example, there was not a single office or anthropologist assigned to analyze human skeletal remains in Uruguay. In 1991 the Laboratorio de Antropología Forense at the Morgue Judicial of Montevideo was created. A total of 189 forensic anthropological cases (276 individuals) were analyzed since this date. Twenty six percent of cases involving human remains were positively identified. The majority came from the Departamento de Montevideo, the largest population district of the country. Most of the cases fell into the 60 to 69 years old age range (35%). Females represented 32% of the total. Since the establishment of the laboratory, the number of forensic cases increased considerably from 20 in 1991 to 40 in 1997. The case studies were accompanied with skull-photo superimposition and facial reconstruction when no other evidence for positive identification was available. This service provided by the laboratory was quickly known to coroners, law enforcement agencies, and other legal authorities and thus utilized not only in Uruguay but also in several other countries in the continent. Because of the obvious need for an anthropologist, there are now university programs to provide forensic anthropological education. Yet, research has lagged behind considerably. Deficiencies are obvious in basic osteological standards of estimating age, calculating stature, determining sex and assessing race that can be applied to populations of the continent. Regional standards are also needed to estimate postmortem interval, to identify culture specific causes of trauma and other forensic phenomena. Some of these can be remedied if there is a database where the available literature is stored and osteometric information is shared.

Global forensic anthropology in the 21st century

While it has a long history, the last 30 years have brought considerable advances to the discipline of forensic anthropology worldwide. Every so often it is essential that these advances are noticed and trends assessed. It is also important to identify those research areas that are needed for the forthcoming years. The purpose of this special issue is to examine some of the examples of research that might identify the trends in the 21st century. Of the 14 papers 5 dealt with facial features and identification such as facial profile determination and skull-photo superimposition. Age (fetus and cranial thickness), sex (supranasal region, arm and leg bones) and stature (from the arm bones) estimation were represented by five articles. Others discussed the estimation of time since death, skull color and diabetes, and a case study dealing with a mummy and skeletal analysis in comparison with DNA identification. These papers show that age, sex, and stature are still important issues of the discipline. Research on the human face is moving from hit and miss case studies to a more scientifically sound direction. A lack of studies on trauma and taphonomy is very clear. Anthropologists with other scientists can develop research areas to make the identification process more reliable. Research should include the assessment of animal attacks on human remains, factors affecting decomposition rates, and aging of the human face. Lastly anthropologists should be involved in the education of forensic pathologists about osteological techniques and investigators regarding archaeology of crime scenes.

Forensic anthropology in the 1990s.

Forensic anthropology has undergone considerable change over the past 10 years. Today it is utilized by most law enforcement, coroner, and medical examiner systems. The techniques for determination of age at death, sex, race, and stature from skeletal remains have been modified and greatly expanded. The role of the forensic anthropologist within a medicolegal context is much broader than in previous years. In addition to establishing individual identity, forensic anthropologists are now consulted for trauma analysis, facial reconstruction, photographic superimposition, determination of time interval since death, and crime-scene recovery. Not all physical anthropologists are forensic anthropologists. Qualified individuals are certified, through rigorous examination, by the American Board of Forensic Anthropology. A list of board-certified forensic anthropologists may be obtained through the American Academy of Forensic Sciences.     

Facial soft tissue thickness in skeletal type I Japanese children

Facial reconstruction techniques used in forensic anthropology require knowledge of the facial soft tissue thickness of each race if facial features are to be reconstructed correctly. If this is inaccurate, so also will be the reconstructed face. Knowledge of differences by age and sex are also required. Therefore, when unknown human skeletal remains are found, the forensic anthropologist investigates for race, sex, and age, and for other variables of relevance. Cephalometric X-ray images of living persons can help to provide this information. They give an approximately 10% enlargement from true size and can demonstrate the relationship between soft and hard tissue. In the present study, facial soft tissue thickness in Japanese children was measured at 12 anthropological points using X-ray cephalometry in order to establish a database for facial soft tissue thickness. This study of both boys and girls, aged from 6 to 18 years, follows a previous study of Japanese female children only, and focuses on facial soft tissue thickness in only one skeletal type. Sex differences in thickness of tissue were found from 12 years of age upwards. The study provides more detailed and accurate measurements than past reports of facial soft tissue thickness, and reveals the uniqueness of the Japanese child's facial profile.     

Becoming respectable: T. Dale Stewart and the acceptance of forensic anthropology in the academic community

Before World War II, forensic anthropology was of peripheral interest to a few anthropologists willing to assist in investigations by law enforcement agencies. A strong bias that "police work" was unbecoming to the scholarly pursuits of academics persisted into the post-war years. Changes took place as a consequence of T. Dale Stewart's case work in the identification of human remains with the FBI from 1943 to 1969, his directorship of the National Museum of Natural History (Smithsonian Institution) beginning in 1962, and his work with the Armed Forces after 1948. This paper discusses the historic period of transition of attitudes and practices in the contexts of Stewart's contributions and the cases and teaching programs of one of his contemporaries. Theodore D. McCown at the University of California at Berkeley, during the period of 1939 to 1969. The establishment of the Physical Anthropology Section within the American Academy of Forensic Sciences in 1972 and the creation of the T. Dale Stewart award for distinguished service in forensic anthropology advanced those laboratory research programs and medical-legal investigations conducted by present-day forensic anthropologists.     

Disaster victim identification: new applications for postmortem computed tomography

Abstract:  Mass fatalities can present the forensic anthropologist and forensic pathologist with a different set of challenges to those presented by a single fatality. To date radiography has played an important role in the disaster victim identification (DVI) process. The aim of this paper is to highlight the benefits of applying computed tomography (CT) technology to the DVI process. The paper begins by reviewing the extent to which sophisticated imaging techniques, specifically CT, have been increasingly used to assist in the analysis of deceased individuals. A small scale case study is then presented which describes aspects of the DVI process following a recent Australian aviation disaster involving two individuals. Having grided the scene of the disaster, a total of 41 bags of heavily disrupted human remains were collected. A postmortem examination was subsequently undertaken. Analysis of the CT images of all body parts ( n  = 162) made it possible not only to identify and side differentially preserved skeletal elements which were anatomically unrecognizable in the heavily disrupted body masses, but also to observe and record useful identifying features such as surgical implants. In this case the role of the forensic anthropologist and CT technology were paramount in facilitating a quick identification, and subsequently, an effective and timely reconciliation, of body parts. Although this case study is small scale, it illustrates the enormous potential for CT imaging to complement the existing DVI process.     

Wilton Marion Krogman, Ph.D. (1903-1987): the end of an era

Dr. Wilton Marion Krogman was one of the major founders of physical and forensic anthropology in the United States. His extraordinary career spanned nearly six decades, and he was universally admired and respected for his scholarship, teaching, research, wit, and humanity. While studies based on human skeletal remains have long been used to assist the medicolegal system, the late Dr. Krogman can be credited with uniting these areas into the discipline of forensic anthropology. His "Guide to the Identification of Human Skeletal Material" (1939) in the F.B.I. Law Enforcement Bulletin became the foundation of this discipline; his monumental book The Human Skeleton in Forensic Medicine (updated with the author in 1986) solidified its establishment. The purpose of this paper is to pay tribute to this great man and outline his influence on the development and advancement of forensic anthropology.     

Discriminant function analysis for sex assessment in pelvic girdle bones: sample from the contemporary Mexican population

Sex assessment of skeletal remains plays an important role in forensic anthropology. The pelvic bones are the most studied part of the postcranial skeleton for the assessment of sex. It is evident that a population-specific approach improves rates of accuracy within the group. The present study proposes a discriminant function method for the sex assessment of skeletal remains from a contemporary Mexican population. A total of 146 adult human pelvic bones (61 females and 85 males) from the skeletal series pertaining to the National Autonomous University of Mexico were evaluated. Twenty-four direct metrical parameters of coxal and sacral bones were measured and subsequently, sides and sex differences were evaluated, applying a stepwise discriminant function analysis. Coxal and sacra functions achieved accuracies of 99% and 87%, respectively. These analyses follow a population-specific approach; nevertheless, we consider that our results are applicable to any other Hispanic samples for purposes of forensic human identification.     

The effects of skeletal preparation techniques on DNA from human and non-human bone

The forensic pathologist increasingly relies on the forensic anthropologist to be the consulting expert in human identification. Likewise, if identification is not possible from visual inspection of skeletal remains, the forensic biologist may be called upon to conduct DNA analysis. The possibility of downstream DNA testing needs to be considered when skeletal preparation techniques are employed to deflesh human remains, as they have the potential to strongly impact genetic analyses and subsequent identification. In this study, three cleaning techniques, boiling bone in water, in bleach, and in powdered detergent/sodium carbonate, were tested for their effect on nuclear and mtDNA recovery from a variety of human and non-human bones. A statistically significant reduction in DNA yields occurred in non-human bones cleaned with bleach, and DNA degradation was apparent electrophoretically. The human bones also showed much lower yields from bleach cleaning, while the detergent/carbonate method allowed the largest segments of DNA to be amplified, indicating it may have a less degradative effect on bone DNA than either of the other cleaning processes.     

A career takes form: Ellis Kerley's tenure at the Armed Forces Institute of Pathology (1957-1966).

From 1957 to 1966, Ellis Kerley was employed at the Armed Forces Institute of Pathology (AFIP) in Washington, DC. Kerley worked in the Orthopedic Pathology section under the supervision of Lent C. Johnson, MD. As the only staff anthropologist at the AFIP, he lectured, conducted research, and consulted on forensic cases. His best-known research completed during these years was the osteon aging technique. He also conducted research and lectured on paleopathology and skeletal identification. Kerley's AFIP experience aided him in pursuing a distinguished career as a forensic scientist, within both academia and the federal government.     

The Status of Forensic Anthropology in Europe and South Africa: Results of the 2016 FASE Questionnaire on Forensic Anthropology

One of the goals of the Forensic Anthropology Society of Europe (FASE) is to map the existing education and practice opportunities in the field of forensic anthropology in order to support the development of the discipline and to optimize the training courses provided by the Society. To address this goal, an online questionnaire was sent to European and South African practitioners of forensic anthropology and related disciplines in 2016. The results of the questionnaire showed that the status and roles of forensic anthropologists vary depending on the national legal systems, education, and employment status of the practitioners. Despite the fact that the expertise of forensic anthropologists has been increasingly requested in a variety of investigations and the spectrum of tasks has become broader, including identification of living persons, specialized education in forensic anthropology is still restricted to a few graduate and postgraduate programs in European countries and to annual FASE courses.     

Human remains sold to the highest bidder! A snapshot of the buying and selling of human skeletal remains on eBay, an Internet auction site

Internet auction sites have become increasingly popular, with diverse items up for sale to the public worldwide. The purposes of this paper are to inform the forensic community that human skeletal remains, old and new, are for sale on the eBay internet auction site, and to advise forensic scientists that eBay does not use a forensic anthropologist to assess photographs of these materials. Over the last few years, this website was "surfed," with numerous auctions during this period. After contacting eBay by email, representatives responded that they adhere to Native American Grave Protection and Repatriation Act (NAGPRA) and that their website indicates that auctions must state that sale of human remains is for instructional purposes only. Based on the photographs, the remains appear to be of prehistoric and modern origin. An unfortunate consequence of such sale may generate interest in stealing remains from graves, mortuaries, hospitals, or county morgues worldwide.     

The human ear: its role in forensic practice

The human ear has much to offer investigators in relation to many areas of forensic practice including forensic pathology, anthropology, identification and facial reconstruction and yet its full potential is often overlooked. This review paper explores current knowledge related to the human ear drawing attention to those situations where the ear could play a valuable role in a forensic investigation.     

Possible express identification of human remains in case of their intense destruction after exposure to physical factors

The problem of identification of human remains is still one of the most difficult and pressing problems of forensic medicine. Such identification is particularly difficult in cases of intense destruction caused by exposure to physical factors (explosion, contusion, fire, compression, etc.). Approaches to identification in such cases are less available and differ essentially from traditional approaches used, for example, in cases when the remains are exposed to natural long-acting factors. This "white spot" is attempted to be liquidated by investigating aircraft accidents with grave destructive results. The potentialities of express identification of human remains in such cases are shown and a complex of characteristic signs which can serve as the landmarks are distinguished. The authors emphasize the strict adherence to certain regulations when working at the site of technogenic disasters and the hazards of disordering the process of identification in case these regulations are neglected.     

Identification of group affinity from cross-sectional contours of the human midfacial skeleton using digital morphometrics and 3D laser scanning technology

Identifying group affinity from human crania is a long-standing problem in forensic and physical anthropology. Many craniofacial differences used in forensic skeletal identification are difficult to quantify, although certain measurements of the midfacial skeleton have shown high predictive value for group classifications. This study presents a new method for analyzing midfacial shape variation between different geographic groups. Three-dimensional laser scan models of 90 crania from three populations were used to obtain cross-sectional midfacial contours defined by three standard craniometric landmarks. Elliptic Fourier transforms of the contours were used to extract Fourier coefficients for statistical analysis. After cross-validation, discriminant functions based on the Fourier coefficients provided an average of 86% correct classifications for crania from the three groups. The high rate of accuracy of this method indicates its usefulness for identifying group affinities among human skeletal remains and demonstrates the advantages of digital 3D model-based analysis in forensic research.     

Pressing need for national governmental recognition of forensic anthropology in South Africa as illustrated in a medico-legal case

Forensic anthropology in South Africa is well developed in the higher education sector, with advanced training and research programmes. Despite this and decades of academic involvement in casework, forensic anthropology still lacks a defined framework and mandate at a governmental level. Therefore, the involvement of forensic anthropologists’ expertise varies markedly between cases, provinces, and among various stakeholders within the country, to the detriment of dispensation of social and criminal justice. The lack of clearly defined guidelines for the rendering of the service was exemplified and demonstrated through a recent forensic case. Here, contextual information was absent, and the remains posed a challenge to analyse, ostensibly due to missing information. Numerous questions were raised during the analysis of the remains, and broader concerns about the investigative involvement of a forensic anthropologist within South African casework were brought to the fore. Through the analysis of this case, we describe the deductive processes that led to the formation of an opinion that the skeletal linear defects were the result of taphonomic changes. In addition, we highlight how these efforts where constrained and each step in the process unnecessarily hindered. Finally, we demonstrate the capacity and willingness of forensic anthropology practitioners to be involved, and how, without governmental support, it is a great potential lamentably untapped.     

Skeletal remains of Dr. Eugenio Antonio Berríos Sagredo

It is often noted that even a well-designed osteological technique may not provide accurate results when applied to single forensic cases. Case studies are ideal to test if this concern is valid, and forensic anthropology is a testing ground for applying a population based standard to individual skeletal remains. Secondly, the increasing role anthropologists have played in forensic sciences has aided the medicolegal disciplines in a number of ways. For example, identification of skeletal remains is now more accurate than ever before. Many of these cases have brought perpetrators to court for justice.The purpose of this paper is to use osteological techniques to analyze skeletal remains and make a positive identification. The victim was found partially buried in the sand near El Pinar, Uruguay in 1995. The analysis indicated that the victim was a 45-year old, white, male who was about 170cm tall. Based on preliminary evidence that the victim might be Dr. Eugenio Antonio Berríos Sagredo, a digital superimposition was made using the victim's photograph and the unknown skull. This examination revealed that the skull corresponded consistently with the individual in the photograph. Results were supported by the fact that personal belongings, such as a medal and wrist watch, also pointed to the same individual. Dental records and radiographs when made available later also indicated the same identity. Dr. Berríos was accused of making nerve gas during the dictatorial regime of former Chilean President General Augusto Pinochet. It was also alleged that he made bombs that killed a Spanish diplomat in his laboratory and a Chilean diplomat in Washington, DC. Many complex techniques are often needed to make a positive identification and such was the case for this study. Because of the nature of anthropology as a holistic discipline, such complexity is an integral part of human biology and behavior and can be used successfully in the forensic sciences and medicolegal investigations.
