Cranial trauma in handgun executions: Circumferential delamination defect and its relationship with contact/close-range shooting.

Skeletal evidence usually constitutes the only source of information to interpret lesion patterns that help to clarify the circumstances surrounding death. The examination and interpretation of bone trauma are essential to the application and utility of anthropology as a forensic science. When discussing the effect of gunshot wounds in bone, it becomes imperative to differentiate between short and long-distance injuries based on clear, distinct, and observable signs.

Peruvian thanatoscape and posthumous biographies of prisoners: dispersion and re-appropriation of undesirable corpses.

This article examines the necropolitical significance of the posthumous biographies of the inmates who were executed in the repression of the Santa Barbara, Lurigancho, and El Frontón prison riots of 1986 in Lima. Of the estimated 250 victims, only 22 have been handed over to their families. The path taken by the bodies is traced, along with the means employed by state agents to conceal them.

The search process: Integrating the investigation and identification of missing and unidentified persons.

The effective search for the missing and identification of persons, alive or dead, are core components in the prevention and in resolving the issue of Missing Persons. Despite the growing literature on this topic, there is still a lack of publications describing the Search as a process that includes different phases inherently composed of forensic investigative and identification principles for both living and deceased missing persons. This paper is the result of discussions between the Forensic Unit of the International Committee of the Red Cross (ICRC) and members of its external Forensic Advisory Board.

Recalibration of the Klales et al. (2012) method of sexing the human innominate for Mexican populations.

Objectives: The aim of this study was to test the accuracy of the Klales et al. (2012) equation for sex estimation in contemporary Mexican population.

Materials And Methods: Our investigation was carried out on a sample of 203 left innominates of identified adult skeletons from the UNAM-Collection and the Santa María Xigui Cemetery, in Central Mexico.

Variation of gunshot injury patterns in mortality associated with human rights abuses and armed conflict: an exploratory study.

Unlabelled: The analysis of the distribution of gunshot injuries in a sample of 777 sets of human remains of proven human rights abuse from Somaliland, the Balkans and Peru is compared to frequencies of injuries sustained by combatants in contemporary conflicts reported in the literature. Principal Component Analysis (PCA) reduced the data to three components accounting for 82.94% of the variance.

Histomorphometric estimation of age in paraffin-embedded ribs: a feasibility study.

Estimation of age at death from human bones in legal medicine or in anthropology and archaeology is hampered by controversial results from the various macroscopic and histological techniques. This study attempted an estimation of age at death by histomorphometric analysis, from the fourth left rib adjacent to the costochondral joint in 80 forensic cases. Use of the picrosirius dye provided a reliable staining of the decalcified paraffin-embedded ribs.

Detection of age-related duplications in mtDNA from human muscles and bones.

Several studies have demonstrated the age-related accumulation of duplications in the D-loop of mitochondrial DNA (mtDNA) extracted from skeletal muscle. This kind of mutation had not yet been studied in bone. The detection of age-related mutations in bone tissue could help to estimate age at death within the context of legal medicine or/and anthropological identification procedures, when traditional osteological markers studied are absent or inefficient.

Sexing and stature estimation criteria for Balkan populations.

Two standard measurements, maximum femur length and head diameter, were collected by International Criminal Tribunal (ICTY) anthropologists. Only Kosovans had both femur dimensions for both sexes. Antemortem stature data were available only for Kosovan and Croatian males.

Analysis of age-at-death estimation through the use of pubic symphyseal data.

The question of whether age parameters derived from an American population will reliably estimate age-at-death for East European skeletal populations is important since the ability to accurately estimate an individual's age-at-death hinges on what standard is used. A reference sample of identified individuals with known ages-at-death from the regions of the Former Yugoslavia (n = 861) is used to determine the age structure of victims and serves as the prior in the Bayesian analysis. Pubic symphyseal data in the manners of Todd (Am J Phys Anthropol, 3 [1920], 285; Am J Phys Anthropol, 4 [1921], 1) and Suchey-Brooks (Am J Phys Anthropol, 80 [1986], 167) were collected for n = 296 Balkan males and females and for n = 2078 American males and females.

When DNA is not available, can we still identify people? Recommendations for best practice.

Recommendations of best practice to conduct identifications in settings with large numbers of victims and technological limitations are provided, based on a sample of 116 cases in which positive presumptive identifications were generated using "traditional" techniques, and were later corroborated through DNA testing. Traditional techniques generally consist of combining witness testimony, personal effects and clothing, anthropological and dental data to corroborate or to exclude the identity of an individual. Experts participating in traditional identifications must develop emic categories to transform objective physical features into recognizable categories by the family, or to do very the opposite-to develop an ethic system by which the expert translates the cues given by a family member into objective categories that are usable in standard forensic and legal contexts.

Skeletal estimation and identification in American and East European populations.

Forensic science is a fundamental transitional justice issue as it is imperative for providing physical evidence of crimes committed and a framework for interpreting evidence and prosecuting violations to International Humanitarian Law (IHL). The evaluation of evidence presented in IHL trials and the outcomes various rulings by such courts have in regard to the accuracy or validity of methods applied in future investigations is necessary to ensure scientific quality. Accounting for biological and statistical variation in the methods applied across populations and the ways in which such evidence is used in varying judicial systems is important because of the increasing amount of international forensic casework being done globally.

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.
