Virtual anthropology and forensic arts: the facial reconstruction of Ferrante Gonzaga

In the last few years virtual anthropology has been used to solve different problems that could not be properly addressed using a traditional anthropological approach. Mainly when dealing with mummies or embalmed bodies, the virtual approach is the only solution to carry out a detailed analysis of the skeleton without jeopardizing the integrity of the physical remains.     

New light on the personal identification of a skeleton of a member of Sir John Franklin’s last expedition to the Arctic, 1845

In 1845, an expedition, commanded by Sir John Franklin, set out to try and discover the north-west passage. All 129 men on this ill-fated voyage perished. Over the years, skeletal remains associated with the final throes of the expedition have been located on and near King William Island, Nunavut, in the Canadian arctic. In general, even a tentative personal identification for these remains has proved impossible. An exception is some skeletal remains that were recovered in 1869 and brought back to England and interred beneath the memorial to the Franklin expedition in Greenwich. In the 19th century, these were tentatively identified as of one of HMS Erebus’s lieutenants, Henry Le Vesconte, a conclusion that has been widely accepted in studies of the Franklin voyage. Renovations to the monument in 2009 provided an opportunity for scientific examination of the remains, and to re-evaluate the personal identification made nearly 140 years before. The current work, which is the first modern scientific analysis of a fairly complete skeleton associated with the Franklin voyage, describes the remains and the artefacts interred with them, discusses the pathological conditions present, and evaluates the personal identification using osteological techniques and isotope geochemistry. Results indicate that the remains are of an adult male of European ancestry. Although some writers have suggested that scurvy or tuberculosis may have been important causes of morbidity and mortality on the Franklin expedition, osteological analysis and, in the case of tuberculosis, DNA analysis, provided no evidence for their presence in these remains. Isotopic studies indicate that the personal identification as Le Vesconte is unlikely to be correct. From the isotopic results and forensic facial reconstruction, HDS Goodsir, an assistant surgeon on the expedition, appears a more likely identification, but the results do not allow a firm conclusion.     

Archaeology and the Forensic Investigation of Recent Mass Graves: Ethical Issues for a New Practice of Archaeology

The close of World War II marked the advent of international human rights legislation and the prosecution of individuals for human rights crimes, by both nation states and international tribunals. The prosecution at such trials often presents evidence from forensically excavated mass graves. Forensic archaeology is a new and expanding field and as such has yet to establish a uniform code of ethics, standard operating procedures, and transparency. In addition, there are complex and conflicting agendas of mass grave excavation. Mass grave investigation in Iraq since the 2003 American-led invasion is presented as a case in point.

Résumé  La fin de la seconde guerre mondiale a marqué l’avènement international de la poursuite judiciaire des individus ayant commis des crimes de guerre et d’une législation des droits de l’homme à la fois de la part des nations et des tribunaux internationaux. La poursuite judiciaire engagée à souvent fourni la preuve de la présence, par excavation, de tombes de masse. L’archéologie des expertises médico-légales est devenue un champ nouveau en pleine expansion, et, en tant que tel, a établi un code éthique généralisé, ainsi que des procédures standard et de transparence. De plus, il existe des agendas complexes et conflictuels de tombes de masse découvertes par excavation. Ceci s’applique à l’Irak depuis 2003 où l’invasion menée par les. américains est sujette à enquête.

Resumen  El fin de la Segunda Guerra Mundial marcó la aparición de una legislación internacional de derechos humanos y los juicios contra los acusados de crímenes contra los derechos humanos, tanto por parte de los estados nacionales como los tribunales internacionales. En los procesos de estos juicios a menudo se presentaban pruebas de la existencia de fosas comunes excavadas por forenses. La arqueología forense es una nueva disciplina en crecimiento y por ello, aún no ha establecido un código ético uniforme, procesos de funcionamiento estándar ni transparencia. Asimismo, hay programas complejos y conflictivos de excavación en fosa comunes. La investigación de fosas comunes en Irak desde la invasión del 2003 encabezada por EE.UU. se presenta como un caso paradigmático.

     

Medical Hermeneutics of Murder. Race,Medicine and Law in a Murder Case from Finnmark, 1911

Abstract

This article seeks to investigate the investigation of a murder case in Finnmark in 1911, where four siblings killed their young brother. In the legal investigations following the misdeed, a number of medical experts played a prominent role. Their role was to assess the mental condition of the defendants, but also to make sense of the murder. A specific interpretational mode was called for: a “medical hermeneutics” of the murder. The murder investigation becomes an occasion for discussing medical and juridical interpretations of human agency at the turn of the century, and especially of the role of the concept of “race” in these interpretations. For at least some of the physicians involved, the racial make-up of the ethnic group to which the actors belonged constituted an inevitable part of the context that made the act intelligible. Although the concept of race, and the conceptual frameworks offered by degenerationism and medical psychology to a certain degree made the act intelligible, these interpretational schemes had little to offer in terms of assessing the legal accountability of the defendants. Hence, the case illustrates the profound epistemological limits of medical interpretation in facing a legal case.     

Panel regression formulas for estimating stature and body mass from immature human skeletons: a statistical approach without reference to specific age estimates

Anthropologists require methods for accurately estimating stature and body mass from the human skeleton. Age-structured, generalized Least Squares (LS) regression formulas have been developed to predict stature from femoral length and to predict body mass in immature human remains using the width of the distal metaphysis, midshaft femoral geometry (J), and femoral head diameter. This paper tests the hypothesis that panel regression is an appropriate statistical method for regression modeling of longitudinal growth data, with longitudinal and cross-sectional effects on variance. Reference data were derived from the Denver Growth Study; panel regression was used to create one formula for estimating stature (for individuals 0.5–11.5 years old); two formulas for estimating body mass from the femur in infants and children (0.5–12.5 years old); and one formula for estimating body mass from the femoral head in older subadults (7–17.5 years old). The formulas were applied to an independent target sample of cadavers from Franklin County, Ohio and a large sample of immature individuals from diverse global populations. Results indicate panel regression formulas accurately estimate stature and body mass in immature skeletons, without reference to an independent estimate for age at death. Thus, using panel regression formulas to estimate stature and body mass in forensic and archaeological specimens may reduce second stage errors associated with inaccurate age estimates.     

The warriors of the steppes: osteological evidence of warfare and violence from Pazyryk tumuli in the Mongolian Altai

Skeletal remains of Pazyryk warriors unearthed in a recent archaeological excavation in the Mongolian Altai offer a unique opportunity for verifying ancient histories of warfare and violence given by Herodotus in the fifth century BC. The Pazyryks were Iron Age nomadic groups associated with the eastern Scythians and known from burial site discoveries on the high steppes of the Altai (Central Asia). The aim of this paper is to analyze the evidence for bone trauma provided by the skeletal remains of these Pazyryk warriors with a particular focus on violence-related injuries. The sample consists of 10 individuals, comprising seven adult males, one adult female and two children. Seven individuals exhibited a total of 14 traumatic injuries. Six of these injuries (43%) showed evidence of bone remodelling and eight injuries (57%) were morphologically compatible with a perimortem origin. Twelve injuries (86%) were related to interpersonal violence, most likely caused by weapons similar to those found in Pazyryk tombs (battle-axes, daggers and arrowheads). Five individuals, including the female and one child, exhibited evidence of violent death. Furthermore, one individual also exhibited evidence of scalping. Despite the small number of Pazyryk skeletons analyzed, the pattern of traumatic injuries observed appears to be in agreement with that documented in conflicts related to raids or surprise attacks, and not a result of routinized or ritualized violence. These findings contribute new data to osteological evidence from Scythian burial sites.     

A new miniSTR heptaplex system for genetic fingerprinting of ancient DNA from archaeological human bone

The analysis of short tandem repeats (STRs) is a useful tool in various contexts of ancient DNA research. Main applications are the reconstruction of kinship, identification, and authentication. Here we describe a short amplicon autosomal short tandem repeat (miniSTR) heptaplex system for the amplification of D13S317, D21S11, D18S51, TH01, D5S818, FGA and Amelogenin from highly degraded DNA as an inexpensive alternative to commercially available kits. All primers were newly designed and the amplicon length of all systems is less than 200 bp, with the exception of some rare alleles in the FGA and D21S11 systems. To validate the suitability of this system for typing STRs from human specimens with low DNA preservation we systematically tested it on 20 skeletal samples from four archaeological sites representing different burial environments and time spans since death. Finally, to test the sensitivity of the heptaplex system, we analyzed serial dilutions of control DNA and ancient DNA extracts. Using the system we were able to reproducibly obtain full STR profiles, down to a concentration of 0.06 ng DNA. Even with 0.004 ng DNA partial profiles could be amplified. The accumulated power of discrimination for the six selected STR loci is 0.99999984, plus the option of genetic sex determination through Amelogenin. The tests conducted prove that the system presented is efficient and especially suited for cases where STRs have to be typed and sex has to be assessed from human specimens with highly degraded DNA.     

Photographic methods to detect colourants in archaeological textiles

Protocols for photography of archaeological textiles to detect components of differing chemistry that are indicative of colourants were developed. Parameters of light source, camera distance, filter type, film type, film speed, and aperture size were evaluated for visible, UV-reflectance, UV-fluorescence, and infrared photography. Using these techniques facilitates selective sampling for further analysis that maximizes critical data acquisition while minimizing destruction of the artefact. Hence, forensic photography of archaeological perishable materials should be regarded as a precursor to destructive analytical methods.     

The Political,Social and Scientific Contexts of Archaeological Investigations of Mass Graves in Spain

The recovery of historic memory of the Spanish Civil War is a multilayered initiative to escape both the romanticism of the Franco era, in which only the glory of the victors was celebrated while their past atrocities were ignored, and the cautiousness of the post-Franco democracy, for which forced amnesia of the Civil War was considered a sacrifice for the greater good. In the past five years the efforts to recover historic memory have gained empirical footing by employing archaeological methods to locate, enumerate and identify the victims of extrajudicial executions. The ultimate goals of such work include the production of a more accurate historical statement of past events, the repatriation of missing persons to their families, and the documentation of physical evidence that may allow families to seek civil restitutions. While the scientific methodology is fairly straightforward, the process is nonetheless inherently political in that various government bodies can and do impede recovery efforts. This paper contextualizes the current political and social climate of human rights investigations in Spain by illustrating some of the recent recovery efforts in Catalonia and Andalucia.
