Abstract
The estimation of the postmortem interval (PMI) is one of the key challenges for forensic anthropologists. Although there are several methods referenced for this purpose, none is sufficiently effective. One of the main reasons justifying the complexity of this task is the influence of several taphonomic factors.The study of the Luminol technique has stood out as a promising method for estimating PMI, complementing the existing methods, since it is an economic, easy and reproducible method that operates as a presumptive test. However, it is not known which taphonomic factors can influence the results obtained by this technique.The aim of this study is to test the influence of taphonomic factors, such as temperature, humidity, soil type and pH, on the estimation of the PMI by the Luminol technique.In order to test the influence of the referred factors, a sample consisting of 30 clavicles, with known and similar PMI, collected from autopsies, was distributed as evenly as possible by six vases and buried with different decomposition conditions for a period of 12 months. After the exhumation and sample preparation, the Luminol technique was applied.It was possible to clearly observe differences in the results. Thus, according to our research, it is possible to conclude that the results obtained by the application of Luminol are influenced by taphonomic factors. Therefore, the context in which a body is found should always be considered for applying this technique.

Abstract
A fundamental goal of evolutionary biology is to understand the mechanisms that generate and maintain biodiversity. Discovery and delimitation of species represent essential prerequisites for such investigations. We investigate a freshwater fish species complex comprising Etheostoma bellator and the endangered E. chermocki, which is endemic to the Black Warrior River system in Alabama, USA, a global hotspot of temperate freshwater biodiversity. Phylogenomic analyses delimit five geographically disjunct species masquerading as E. bellator. Three of these new species exhibit microendemic distributions comparable to that of E. chermocki raising the possibility that they also require protection. The species of the complex are found in streams flowing over carbonate rock and they are separated by waterways flowing over siliciclastic rock, a geographic pattern dictated by the underlying stratigraphy and structural geology. Over time, rivers have eroded downward through layers of siliciclastic rocks in the basin, gradually exposing underlying carbonate rock, the substrate of suitable habitat today. Our results suggest that episodic dispersal to patches of suitable habitat set the stage for allopatric speciation in the species complex. Our study suggests that the presence of heterogeneous rock can facilitate dispersal-mediated allopatric speciation in freshwater organisms in the absence of external tectonic or climatic perturbations.

Abstract
Sodium nitrite (SN) is an inorganic salt that appears as a slightly yellowish crystalline solid, odorless, and highly soluble in water at room temperature. It is highly toxic to humans at specific doses because it can oxidize hemoglobin to methemoglobin, causing severe tissue hypoxia. A 20-year-old woman was unconscious in her bedroom and died shortly after that. Two days later, following the discovery of a jar of SN and a paper in which were written instructions on how to take it (and the website from which the procedure was learned) in the same room were death occurred, the Judicial Authority ordered the execution of the autopsy on the exhumed body of the young woman. The autopsy procedure was performed ∼ 2h after exhumation. It showed greyish-purple hypostasis, labial cyanosis, stomach distension and greenish color but empty, subpleural petechiae, brownish fluid in the pleural cavities (∼300 ml), congested and edematous lungs and diffuse visceral congestion. At autopsy, foamy liquid was observed at the lung section and subsequent squeezing. In addition, the autopsy showed edema and hemorrhagic petechiae of the laryngeal, glottal, and tracheal submucosa and green-brownish foamy liquid in the tracheal lumen. The cause of death was attributed tocardiac arrest induced by anoxia resulting from acute methemoglobinemia caused by sodium nitrite poisoning, intensified by severe malnutrition. Manner of death was suicidal.

Abstract
Heinous crimes and brutalities have decimated humanity throughout human history. In modern times, forensic anthropologists have helped to reconstruct the nature and mechanism, intent and purpose, manner, and circumstances of various inhumane instances of genocides and violent crimes. Anthropologists endeavor to bring closure and comfort to bereaved families by disseminating information about the location, exhumation, and identification of the remains of victims. The methodological armamentarium and scope of forensic anthropology have developed much beyond the realms of the traditional biological profiling casework to the scenarios of humanitarian concerns. Humanitarian forensics focuses on the excavation and identification of the remains of victims and facilitates the dignified burial of the deceased. This review article highlights and exemplifies the significant contributions of forensic anthropological expertise in revealing various crimes against humanity and human rights violations committed in the recent past as well as in some contemporary cases reported from around the globe. It includes cases such as Guatemalan, Cambodian, and Bosnian genocides, as well as other mass killings that illustrate the efficacy of anthropological evidence in reconstructing the nature, mechanism, and circumstances related to these incidences. Special emphasis is given to the Ajnala (India) skeletal remains excavated from an abandoned well - remains reportedly belonging to 282 Indian soldiers killed in 1857 whose corpses were dumped into the said disused well by sanitary workers - indicating the importance of forensic anthropology in authenticating the occurrence of events as mentioned in historical records. Analysis of different case histories reveals that forensic anthropologists have played a significant role in recovery and identification of the victims of the many war crimes, genocides, racial conflicts, and violent cruelties committed against mankind in modern history.

Abstract
Estimation of the postmortem interval in advanced postmortem stages is a challenging task. Although there are several approaches available for addressing postmortem changes of a (human) body or its environment (ecologically and/or biochemically), most are restricted to specific timeframes and/or individual and environmental conditions. It is well known, for instance, that buried bodies decompose in a remarkably different manner than on the ground surface. However, data on how established methods for PMI estimation perform under these conditions are scarce. It is important to understand whether and how postmortem changes are affected under burial conditions, if corrective factors could be conceived, or if methods have to be excluded for respective cases. We present the first multi-methodological assessment of human postmortem decomposition carried out on buried body donors in Europe, at the Amsterdam Research Initiative for Sub-surface Taphonomy and Anthropology (ARISTA) in the Netherlands. We used a multidisciplinary approach to investigate postmortem changes of morphology, skeletal muscle protein decomposition, presence of insects and other necrophilous animals as well as microbial communities (i.e., microbiomes) from August to November 2018 associated with two complete body exhumations and eight partial exhumations. Our results clearly display the current possibilities and limitations of methods for PMI estimation in buried remains and provide a baseline for future research and application.

Abstract
The Second Republic of Austria was established after the Second World War. As a former part of the Austro-Hungarian Monarchy and subsequently Nazi Germany, its history is strongly shaped by two world wars and the deaths of millions of people. The handling of human remains and graves of victims of National Socialist terror, members of the armed forces of nations participating in the world wars as well as civilian casualties that are located on today's federal territory, has been regulated by law since 1948. The responsibility officially lies with the Federal Ministry of the Interior / Department for War Graves Services. In practice, various institutions and interest groups have been involved in the identification and maintenance of so-called "war graves" and the recovery of human remains. This article aims to provide a brief outline of the current legal situation in Austria and discusses varying practices of handling war graves by presenting historical and recent examples.

Abstract
Forensic examination of skeletal remains exhumed in 2012 from the site of the former Church of the Greyfriars in Leicester, United Kingdom, revealed a gracile adult male of around 30 to 34 years of age with 11 perimortem injuries. These were consistent with descriptions of injuries sustained by King Richard III, the last Plantagenet King of England, at the Battle of Bosworth Field in 1485. Combining these features with DNA analyses proved that the remains were those of Richard. The finding of a severe thoracic scoliosis with a raised right shoulder confirmed that the king did have a" hunchback" which was not a later invention of Tudor and subsequent chroniclers. This investigation provides an excellent demonstration of how contemporary forensic techniques can answer historical questions. The remains of the last Plantagenet king have been identified, his vertebral disease confirmed, and the nature of his last moments verified.

Abstract
In 1949, the American Graves Registration Service Pacific Zone proposed the identification of 27 sets of remains (skulls/crania/mandibles) based on comparisons with written dental records. All were denied, and the remains were buried as unknowns. In 2003 and 2015, the remains were exhumed by the DPAA. Currently, 26 individuals previously recommended for identification have been positively identified. The DPAA Science Director's opinion corresponded with 24 of their recommendations, while DNA excluded three. Caution should be taken by the forensic scientist when building assemblages through skeletal and dental articulation. The forensic odontologist must always consider variations in restorative care/extraction patterns and the possibility of documentation errors when reviewing/interpreting historical and current day dental records used for AM/PM comparisons. The odontologist should base their opinion on the strength of the antemortem/postmortem comparison, number and type of concordances, and distinct dental care and extraction patterns.

Abstract
This article examines the use of critical pedagogy practices for teaching students the forensic science of migrant death and identification in the US borderland. Critical pedagogy, a philosophy of education that centers issues of social justice and human rights in the classroom, insists that teaching is inherently political, and challenges students to recognize and address power structures which perpetuate an unjust status quo. Drawing examples from qualitative data gathered during two field seasons in South Texas with the University of Indianapolis Forensic Science Team and narrative analysis of students team members' daily reflections about their work within structures designed to address the US border crisis, this article illuminates challenges and possibilities for teaching in learning in a context of mass violence.

Abstract
The study of carrion fauna associated with buried human corpses from a forensic perspective could provide useful information in criminal investigations. Insects and other arthropods remains sampled of 44 legally exhumed infant skeletons from La Plata (Buenos Aires, Argentina). They were identified at different taxonomic levels depending on the state of preservation. The specific diversity, abundance and frequency were analyzed and each taxon was assigned to the hypothetical colonization sequence: burial colonization, post-exhumation contamination at cemetery deposit or soil fauna. The phorid Dohrniphora sp. is mentioned for the first time in Argentina as carrion fauna of underground colonization, and the assemblage of Dohrniphora sp., Megaselia scalaris and Hydrotaea aenescens is proposed as indicator of buried cadavers. These findings provide new useful data to be applied in forensic entomology research.

Abstract
The body of a mediaeval monarch was always under scrutiny, and Richard III's was no exception. In death, however, his body became subject to new forms of examination and interpretation: stripped naked after the battle of Bosworth, his corpse was carried to Leicester and exhibited before being buried. In 2012, it was rediscovered. The revelation that Richard suffered from scoliosis prompts this article to re-evaluate the historical sources about Richard's physique and his posthumous reputation. This article argues that Richard's death and his myth as 'crookback' are inextricably linked and traces attitudes to spinal curvature in the early modern period. It also considers how Shakespeare represented Richard as deformed, and aspects of performance history which suggest physical vulnerability. It then considers Richard's scoliosis from the perspective of medical history, reviewing classical accounts of scoliosis and arguing that Richard was probably treated with a mixture of axial traction and pressure. It demonstrates from the evidence of Richard's medical household that he was well placed to receive hands-on therapies and considers in particular the role of his physician and surgeon, William Hobbes. Finally, it shows how the case of Richard III demonstrates the close relationship between politics and medicine in the period and the contorted process of historical myth making.

Abstract
Forensic investigations have been embraced in many developed countries to help investigate homicidal cases in their legal system amongst others. It is however still in infancy state in many developing countries, including Nigeria, making the use of this very vital tool very limited to prosecute cases. Some of the reasons include the low knowledge base of the investigating officers, to the dearth of Forensic personnel and the inability to use the findings to prosecute the offenders. The few cases where proper investigation is done, anatomic pathologists and sometimes medical officers are usually called to provide the forensic evidence. Often this involves exhumation of corpse. Exhumation of corpses for death investigation is not a common occurrence in Nigeria and we present the findings seen in these cases.

Abstract
Forensic anthropologists and pathologists are more and more requested to answer questions on bone trauma. However limitations still exist concerning the proper interpretation of bone fractures and bone lesions in general. Access to known skeletal populations which derive from cadavers (victims of violent deaths) who underwent autopsy and whose autopsy reports are available are obvious sources of information on what happens to bone trauma when subjected to taphonomic variables, such as burial, decomposition, postmortem chemical and mechanical insults; such skeletal collections are still however quite rare. This study presents the results of the comparative analysis between the autopsy findings on seven cadavers (six of which victims of blunt, sharp or gunshot wounds) and those of the anthropological assessment performed 20 years later on the exhumed dry bones (part of the Milano skeletal collection). The investigation allowed us to verify how perimortem sharp, blunt and gunshot lesions appear after a long inhumation period, whether they are still recognizable, and how many lesions are no longer detectable or were not detectable at all compared to the autopsy report. It also underlines the importance of creating skeletal collections with known information on cause of death and trauma.

Abstract
Paleoparasitology is the science that uses parasitological techniques for diagnosing parasitic diseases in the past. Advances in molecular biology brought new insights into this field allowing the study of archaeological material. However, due to technical limitations a proper diagnosis and confirmation of the presence of parasites is not always possible, especially in scarce and degraded archaeological remains. In this study, we developed a Molecular Paleoparasitological Hybridization (MPH) approach using ancient DNA (aDNA) hybridization to confirm and complement paleoparasitological diagnosis. Eight molecular targets from four helminth parasites were included: Ascaris sp., Trichuris trichiura, Enterobius vermicularis, and Strongyloides stercoralis. The MPH analysis using 18th century human remains from Praça XV cemetery (CPXV), Rio de Janeiro, Brazil, revealed for the first time the presence E. vermicularis aDNA (50%) in archaeological sites of Brazil. Besides, the results confirmed T. trichiura and Ascaris sp. infections. The prevalence of infection by Ascaris sp. and E. vermicularis increased considerably when MPH was applied. However, a lower aDNA detection of T. trichiura (40%) was observed when compared to the diagnosis by paleoparasitological analysis (70%). Therefore, based on these data, we suggest a combination of Paleoparasitological and MPH approaches to verify the real panorama of intestinal parasite infection in human archeological samples.

Abstract
In the aetiology of maxillofacial injuries, car accidents, violence, sports injuries and lately war injuries are frequently mentioned. The purpose of this study was to exhibit and analyse types of jaw injuries on bodies exhumed from massive and individual graves located in regions temporarily occupied during the War in Croatia that lasted from 1991 to 1995. The sample was the post-mortal documentation of the orofacial region (set of teeth, photographs, radiographic images) of 1068 victims exhumed from massive grave sites in Croatia. The jaw traumatism was analysed on the whole sample as well as on individual graves, whilst the analysis of trauma frequency was performed separately. Descriptive statistics were computed and the value of P < .05 was accepted as statistically significant. Results of this study showed that out of 1068 examined corpses, 332 had midface and lower face fractures, which was 31.1% of the total number. Lower face fractures were more frequent with 28.1%. Age related frequency analysis showed a significant dependency. There were 34.6% of fractures in the under 30 age group, 34.2% in those aged 30-60, while 21.3% of fractures were noted in the over 60 age group. Female bodies had the lowest number of jaw fractures regardless of the osteoporotic changes. The results of this study suggest that younger and middle aged persons were molested more. Jaw fractures suggest ante-mortal molestation. In females, the more likely fracture causes were the falls of the bodies into the graves or body to body hits.

Abstract
The aim of this study was the genetic identification of Nazi repression victims. Human remains were found in 2011 in the area of former military training ground BRUS in Lodz. Genetic tests were performed upon the request of the Departmental Commission for the Prosecution of Crimes against the Polish Nation of the Institute of National Remembrance in Lodz. The research material was provided by the Institute of Archaeology (University of Lodz). It consisted of bones and teeth which were exhumed from mass Grave No 7. As a reference material we used a buccal swab collected from the putative son of one of the victims. Genomic DNA was extracted from the skeletal samples using the PrepFiler BTA Forensic DNA Extraction Kit. DNA was amplified using the AmpFlSTR Identifiler Plus PCR Amplification Kit and analyzed using an AB 3500 genetic analyzer. The obtained results showed 12 male genetic profiles. The analysis excluded paternity of 10 investigated victims. The genetic data of the remaining samples did not allow for paternity settlement.

Abstract
This study examined pig carcasses buried at two different depths, 30 and 60 cm, to determine if insects were able to colonize buried carcasses, when they arrive at each depth, and what fauna were present over seven sampling dates to establish an insect succession database on buried carrion in East Lansing, MI. Thirty-eight pigs were buried, 18 at 30 cm and 20 at 60 cm. Four control carcasses were placed on the soil surface. Three replicates at each depth were exhumed after 3, 7, 14, 21, 30, and 60 d, respectively. One pig also was exhumed from 60 cm after 90 d and another after 120 d. Sarcophaga bullata (Parker) (Diptera: Sarcophagidae) and Hydrotaea sp. (Diptera: Muscidae) were found colonizing buried carrion 5 d after burial at 30 cm. Insect succession at 30 cm proceeded with flesh and muscid flies being the first to colonize, followed by blow flies. Insects were able to colonize carcasses at 60 cm and Hydrotaea sp. and Megaselia scalaris (Loew) (Diptera: Phoridae) were collected 7 d after burial. Insect succession at 60 cm did not proceed similarly, instead muscid and coffin flies were the only larvae collected. Overall these results reveal postburial interval estimates for forensic investigations in mid-Michigan during the summer, depending on climatic and soil conditions.

Abstract
The Krakow Department of Forensic Medicine was granted a unique opportunity to examine the body of a historical figure, i.e. General Władysław Sikorski, the Prime Minister of the Polish government in exile, deceased in 1943. General Sikorski died in the crash of a Liberator aircraft at Gibraltar, and the British commission investigating the crash decided it had been an accident. In the past several decades, doubts have been repeatedly expressed as to the circumstances of the General's death and the theory of assassination has become very popular. On November 25, 2008, the General's corpse buried in the cathedral of the Royal Castle on Wawel Hill in Krakow was exhumed and the body was thoroughly examined. The examinations demonstrated numerous fractures of the cranium, spine and extremities, the character of which corresponded to effects of an air crash. Based on corpse examination alone it was impossible to establish whether the air crash had been an effect of sabotage or an ill-fated accident. Although no typical evidence of intravitality was found, such as bruises or fat embolisms, yet the character of some fractures suggested that they had been incurred intravitally. These were represented by a spiral fracture of the femoral bone shaft, a fracture of the sustentaculum tali of the calcaneal bone and fractures of the transverse processes of the lumbar vertebrae.

Abstract
A 36-year-old woman consulted the medical emergency unit of a private health center for abdominal pain and gastroenteritis of 5 days duration. Acute right pyelonephritis was diagnosed. Five hours after admission she became unconscious in a state of clinical shock. She was transferred to an intensive care unit but resuscitation attempts were unsuccessful and she died 3h later. Three days after death, she was buried in the family vault. Five days after the burial, her husband lodged a complaint with the public prosecutor because he had not received a clear explanation from the physicians concerning the cause of his wife's death. After analysis of the medical records of the deceased by two forensic pathologists, a medicolegal autopsy was ordered by the public prosecutor. The corpse was exhumed and autopsy performed 9 days after death. Massive hemoperitoneum was diagnosed with a macroscopically ruptured subcapsular hematoma. Pathological study confirmed acute right pyelonephritis and demonstrated the precise cause of the hemorrhage: rupture of the hepatic artery at the hilar part, following infectious arteritis which was probably secondary to the acute pyelonephritis. To the best of our knowledge, this is the first published report of such a case.

Abstract
This special issue of The Public Historian will examine what is a pressing, pervasive, traumatic, and very public contemporary issue in which history and historians are heavily involved in many countries around the globe. Authors will investigate a range of issues around the state involvement in death, including the role of the state as perpetrator and its responsibilities to the victims and their families; the process and significance of exhumation, of identification, and of repatriation; the status of refugees and displaced peoples who die when legally stateless and so without state protection; the differing transnational stances in tracing and punishing the perpetrators; the fraught issue of personal and official reparation; and the role and efficacy of international justice.

Abstract
Patio 29 lies in the northern sector of Santiago's General Cemetery. To the naked eye, it is a grim unweeded field of some twelve hundred rusted tin crosses. But to the families of the 1,197 detained-disappeared during Augusto Pinochet's brutal dictatorship, Patio 29 is both a site of horror and a site of hope. Its story begins in September-December 1973 when 320 early victims of the repression were brought there in makeshift wooden crates that held as many as three bodies each, and buried in unmarked graves. A few years later, two hundred of those graves were exhumed by the military, and the remains presumably cremated. For another decade, the mass grave remained silent, yielding few of its secrets to the families' demands to know: Where are they? Today, nineteen years into the so-called transition to democracy, Patio 29--the most important single finding in relation to Chile's detained-disappeared-still refuses to reveal the identities of those victims, pressing upon the government of Michelle Bachelet a new question: Who are they? First state terror, now state error have conspired to make Patio 29 one of Chile's principal horror-cum-hopescapes.

Abstract
BACKGROUND Foul play in cases of hurt and homicide is an established fact. People on basis of enmity falsely charge their enemies; this practice is carried out globally. The purpose of present study was to know the situation in the study area and also to know the risk factors which make hindrance in providing justice in exhumed cases. METHODS The present study was conducted over a period of 3 and half years from July 2006 to Dec 2009. During the said period total 21 exhumations were carried out in Sukkur and Larkana Divisions by the team of Chandka Medical College, Larkana. Cases were studied in Forensic Medicine Department of Chandka Medical College, Larkana. Out of 21 cases, only 9 cases were positive (autopsy). In rest of 12 cases, autopsy reports remained undetermined due to advanced decomposition/putrefaction of corpses. RESULTS During the study period, total 21 exhumations (autopsies) were carried out in different districts of Larkana and Sukkur divisions. There were 17 male cases and 4 female cases. Cases were divided in to 4 groups on age basis. Group-1 from 0-5 years, Group-2 from 16-30 years, Group-3 from 31-45 years, Group-4 from 46-65 years. The maximum number of cases fall in group-2 which are 15 (71.42%) and minimum in group-1 which is 1 (4.76%). Out of 21 cases, only in 9 cases cause of death was ascertained and majority of these were firearm injuries (5, 55.55%), two (22.22%) cases of drowning, one (11.11%) strangulation and one blunt trauma. The success rate remained 42.85%. Nineteen cases were of primary autopsy (First time) on exhumation and 2 cases were secondary (re-examination). CONCLUSION The success rate in challenge cases depends mostly on the duration of exhumation and soil of cemetery. If a foul play is suspected then there should be no unnecessary delay in conduction of exhumation. If exhumation is carried out within days after burial, 90% results can be achieved.

Abstract
The aim of the present investigation was personal identification of an unknown man whose remains were exhumed four years after burial. The femur of the deceased was secured for the genetic analysis. The comparative material included buccal swabs collected from the putative relatives of the deceased, i.e. the wife, son and brother. Genomic DNA was extracted from the bone using two methods: traditional isolation with phenol/chloroform and as a alternative technique, a simple and rapid method described by T. Kalmár et al. The results were then compared. The specimens underwent DNA amplification using the AmpFISTRSEfiler PCR Amplification Kit. The authors obtained a full STR profile of the unknown man from each isolate, yet the DNA extraction method proposed by T. Kalmár et al. allowed for simpler and faster isolation of genetic material. The statistical analysis of the obtained results confirmed the paternity of the deceased and established his son as his rightful child (P = 99.999999%), also confirming the consanguinity between the investigated individual and his putative brother (P = 99.9999%).

Abstract
Six dry skulls were studied by multislice computed tomography (MSCT). They had not previously been prepared, and were natural skeletonized remains. All had been found in the soil. Examination focused on the temporal bones and the ear structures. In all cases, either disruption of the ossicular chain or absence of some ossicular bones were noted. The authors concluded that the fragile ossicles were disrupted in the post-mortem state, and were not indicative of ante-mortem pathology. These observations illustrate the ability of MSCT to visualize taphonomic changes. To further illustrate these findings, we present the results of MSCT performed on an exhumed body. The left ossicular bones were missing and the right ossicular chain was disrupted. With the development of forensic radiology, structures as tiny as the ossicles can be examined. However, the radiologist who performs post-mortem imaging must be familiar with taphonomic changes to avoid interpretation as ante-mortem or peri-mortem traumatic injuries. This could potentially have considerable judicial impact, especially in the study of exhumed bodies.

Abstract
Despite an increasing literature on the decomposition of human remains, whether buried or exposed, it is important to recognise the role of specific microenvironments which can either trigger or delay the rate of decomposition. Recent casework in Northern England involving buried and partially buried human remains has demonstrated a need for a more detailed understanding of the effect of contrasting site conditions on cadaver decomposition and on the microenvironment created within the grave itself. Pigs (Sus scrofa) were used as body analogues in three inter-related taphonomy experiments to examine differential decomposition of buried human remains. They were buried at three contrasting field sites (pasture, moorland, and deciduous woodland) within a 15 km radius of the University of Bradford, West Yorkshire, UK. Changes to the buried body and the effect of these changes on hair and associated death-scene textile materials were monitored as was the microenvironment of the grave. At recovery, 6, 12 and 24 months post-burial, the extent of soft tissue decomposition was recorded and samples of fat and soil were collected for gas chromatography mass spectrometry (GCMS) analysis. The results of these studies demonstrated that (1) soil conditions at these three burial sites has a marked effect on the condition of the buried body but even within a single site variation can occur; (2) the process of soft tissue decomposition modifies the localised burial microenvironment in terms of microbiological load, pH, moisture and changes in redox status. These observations have widespread application for the investigation of clandestine burial and time since deposition, and in understanding changes within the burial microenvironment that may impact on biomaterials such as hair and other associated death scene materials.

Abstract
In the course of an exhumation performed 5.5 years after death, several bone fragments were uncovered during the excavation of the clay-rich soil. Amongst others, there was a large piece of the frontal neurocranium. In addition, a so-called coffin stain was discernible. The exhumed coffin was intact. The forensic autopsy revealed a complete corpse with distinct adipocere formation. Consultation with the cemetery administration allowed the conclusion that the additional bone fragments were from the first use of the grave approximately 100 years ago. The heavily soil-encrusted skull fragment bore clear signs of a half sharp force, that could immediately be classified as postmortem. The pattern of injury pointed to an excavator as the cause. However, the question arose whether the postmortem trauma occurred 5.5 years ago during the excavation of the grave or during the current exhumation. First the skull fragment was dried. However, it was then impossible to remove the clay-rich soil without damaging the bone. The fragment was therefore carefully washed and dried again. The cut and fracture areas then showed distinctly lighter surfaces than the rest of the bone, which pointed to the exhumation as the time of origin. For comparison, fresh injuries were inflicted with a hatchet. These distinctly showed even lighter surfaces, so that the time of origin could be assumed to have been during the excavation of the grave 5.5 years ago.

Abstract
The authors participated in the activity of a group of European experts who visited Moscow, Rostov-on-Don and Grozny in September 2005 to clarify situation with identification of exhumed unknown dead bodies of the civil population. The European experts recommend to set up Center for Identification in Chechen Republic (in Grozny). The authors propose to make DNA identification tests in the Russian Federation Center for Forensic Medical Evaluation in Moscow which has much experience and staff skilled in identification of unknown exhumed bodies and can solve the problem of genetic identification of unidentified bodies of people missed in the Chechen Republic more effectively.

Abstract
We report on the mitochondrial DNA (mtDNA) analysis of the supposed remains of Francesco Petrarca exhumed in November 2003, from the S. Maria Assunta church, in Arquà Padua (Italy) where he died in 1374. The optimal preservation of the remains allowed the retrieval of sufficient mtDNA for genetic analysis. DNA was extracted from a rib and a tooth and mtDNA sequences were determined in multiple clones using the strictest criteria currently available for validation of ancient DNA sequences, including independent replication. MtDNA sequences from the tooth and rib were not identical, suggesting that they belonged to different individuals. Indeed, molecular gender determination showed that the postcranial remains belonged to a male while the skull belonged to a female. Historical records indicated that the remains were violated in 1630, possibly by thieves. These results are consistent with morphological investigations and confirm the importance of integrating molecular and morphological approaches in investigating historical remains.

Abstract
From 1997 to 2002 the United Nations International Criminal Tribune for the former Yugoslavia (ICTY) undertook the exhumation of mass graves in NE Bosnia as part of the war crimes investigations aimed at providing evidence for the prosecution of war criminals in The Hague. This involved the location and exhumation of seven former mass graves (primary sites) dug following the fall of Srebrenica in July 1995. These primary mass graves were secretly and hurriedly exhumed three months later and most of the bodies or body parts transported and reburied in a large number of secondary sites many of which were subsequently exhumed by ICTY. The aim of the pollen and soil/sediment studies was to provide an 'environmental profile' of the original site of the samples and use this to match the relocated bodies to the original mass graves. This was part of completing the chain of evidence, providing evidence of the scale and organization of the original atrocities and the subsequent attempts to conceal the evidence related to them. All the primary sites were located in areas of contrasting geology, soils and vegetation, and this allowed matching of the sediment transported in intimate contact with the bodies to the original burial sites, which in some cases were also the execution sites. In all, over 24 sites were investigated, over 240 samples collected and analyzed under low power microscopy and 65 pollen sub-samples fully analyzed. The pollen and sediment descriptions were used in conjunction with the mineralogy (using XRD) of primary and secondary sites in order to provide matches. These matches were then compared with matching evidence from ballistic studies and clothing. The evidence has been used in court and is now in the public domain. It is believed this is the first time 'environmental profiling' techniques have been used in a systematic manner in a war crimes investigation.

Abstract
Two patients, a 36-year-old female and a 36-year-old male, separately experienced new onset nausea, vomiting, diarrhea, abdominal pain, muscle weakness and pallor. Over a period of 14-16 h these symptoms continue and progress to include hypotension refractory to therapy, pulmonary edema and cardiovascular collapse. Autopsies show hemorrhagic pulmonary edema, splenomegaly and lack of anatomical cause for sudden death. Postmortem analysis, in one case post-embalming and exhumation, revealed elevated selenium concentrations and a determination of the cause of death. These two cases present several important features associated with selenium toxicity, two of which are previously unreported: (1) selenium as a potential homicidal agent, (2) the toxidrome and time frame of selenium toxicity, (3) selenium determination in exhumed, embalmed tissues, (4) postmortem urinary selenium concentration, and (5) decrease in tissue concentrations over time.

Abstract
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.

Abstract
Mivacurium is a muscle relaxant that is used in hospitals and has been implicated in a number of homicides. A validated, sensitive method for the analysis of mivacurium and metabolites from biological specimens is presented here. Sample cleanup involves the precipitation of proteins with acetonitrile followed by analyte isolation using a commercially available solid-phase extraction column. Screening is performed by liquid chromatography with fluorescence detection, and confirmation is performed by liquid chromatography with tandem mass spectrometric detection. This method has been used to analyze dozens of forensic samples, including clinical specimens from living patients, as well as autopsy specimens from exhumed bodies.

Abstract
To determine how long pathological findings persist after burial and which factors play a role in decomposition of a corpse, we evaluated all bodies exhumed under the auspices of the Institute of Legal Medicine at the Hannover Medical School between 1978 and 1997. A total of 87 exhumations (54 men, 33 women) were performed in this period. The time bodies remained buried varied between 5 days and 16.8 years (mean 1.5 years, median 2.3 months). Fifty-six percent of the bodies were exhumed after at most 3 months, 10% remained buried for greater than 3 years. Pathomorphological changes of the soft tissues and the internal organs remained evident after several months, in some cases after several years of burial. Overall, it was possible to evaluate internal organs after 5 years of burial. Bodies became mostly decomposed after approximately 8 years at the earliest, although it was still possible to evaluate some soft tissue remnants after 16.8 years. In stepwise logistic regression, both the length of time the body was buried (p < 0.00005) and the time of year (p < 0.0019) clearly affected the rate of physical change. The variables of sex (p = 0.33), age (p = 0.61) and changes in the integrity of the body before burial (trauma, autopsy before burial; p = 0.15) did not influence the physical state of the body after exhumation. Our data show that much information may be gained from an exhumation even after significant time has passed since burial.

Abstract
After 20 months of interment in a deep grave, the decomposed body of the 81-year old testator of a will was exhumed to sustain the burden of proof that he lacked testamentary capacity when the will was rewritten two days prior to his death. The brain was mushy and pulverized with complete disappearance of the brainstem, cerebellum and subcortical ganglia. Small foci of relatively intact dorsal frontal neocortex were identified. Sections from these foci were stained with hematoxylin and eosin, bielchowsky silver stain and immunostains for beta amyloid peptide (betaA4), tau and alpha-synuclein. Despite severe autolysis and decomposition, the bielchowsky stain and the betaA4 immunostains showed preserved frequent neuritic amyloid plaques with very few residual neurofibrillary tangles. Cerebral Amyloid Angiopathy was present. At the present time this case represents the first documented and reported case of direct tissue diagnosis of Alzheimer's Disease pathology in a decomposed brain following long term burial in a deep grave.

Abstract
The number of cremators is set to grow in Italy owing to current increasing demand for cremation, as a system of burial as well as a system of disposal of non-decomposed human remains resulting from operations of exhumation (as provided by the Circular No. 10 of 31 July of 1998 of the Ministry of Health). Some indications on how town planners need to size up the cremation plant with regard to its capacity to face cremation demand, in order to avoid any hygienic-sanitary inconveniences are given. As a matter of fact, for planning the demand for cremation from Circular No. 10 of 31 July of 1998 it is necessary to assess the decomposition time in burial sites.

Abstract
In a fire tragedy in Manila in December 1998, one of the worst tragic incidents which resulted in the reported death of 23 children, identity could not be established initially resulting in the burial of still unidentified bodies. Underscoring the importance of identifying each of the human remains, the bodies were exhumed 3 months after the tragedy. We describe here our work, which was the first national case handled by local laboratories wherein conventional and molecular-based techniques were successfully applied in forensic identification. The study reports analysis of DNA obtained from skeletal remains exposed to conditions of burning, burial, and exhumation. DNA typing methods using autosomal and Y-chromosomal short tandem repeat (Y-STR) markers reinforced postmortem examinations using conventional identification techniques. The strategy resulted in the identification of 18 out of the 21 human remains analyzed, overcoming challenges encountered due to the absence of established procedures for the recovery of mass disaster remains. There was incomplete antemortem information to match the postmortem data obtained from the remains of 3 female child victims. Two victims were readily identified due to the availability of antemortem tissues. In the absence of this biologic material, parentage testing was performed using reference blood samples collected from parents and relatives. Data on patrilineal lineage based on common Y-STR haplotypes augmented autosomal DNA typing, particularly in deficiency cases.

Abstract
This paper examines the place that forensic archaeologists should hold at scenes of crime where a body has been buried. The forensic archaeologist is rapidly becoming a key player whose specialty should be explained, and role defined. A high level of interaction between the forensic archaeologist and other personnel implies good communications skills as well as a precarious mix of receiving orders, assistance and advice as well as giving directions to other staff. The extent to which each of these should be applied will be discussed as well as underlying the absolute need for forensic archaeologist to attend these types of scenes.

Abstract
Mycobacterium tuberculosis was isolated from the lung tissue of an 86-year-old unembalmed woman who was exhumed for an autopsy 8 days after her death. Autopsy prosectors should consider performing microbiological culture in all cases with a history or gross pathological findings suggestive of an infection even if the postmortem interval is extended. In addition, prosectors should still adhere to biosafety precautions for airborne pathogens, because a long postmortem interval does not necessarily provide assurance that these organisms are not viable.

Abstract
We present a historical example of forensic investigation of civilian victims of an armed conflict. During the Civil War in Finland in 1918, 77 external examinations with photographic documentation and 10 forensic autopsies were carried out. However, incorrect conclusions concerning post-mortem changes made by non-medical persons led into erroneous interpretations of the events. Post-mortem changes were considered to be signs of torture and post-mortem mutilation. This example demonstrates how political purposes may falsify results of a forensic investigation.

Abstract
Mass graves are complex products of large-scale crimes. Such scenes pose four conceptual challenges to investigators and forensic experts: the individual victim, the crime, the setting, and the statistical. Exhumation and post-mortem examination of mortal remains with associated personal and forensic evidence require integrated management of core forensic personnel including investigators, archaeologists, anthropologists, odontologists and pathologists, among whom there is overlapping expertise. The key to avoiding competition and ill-will among experts is to recognize that all such experts should be enabled to make known how their expertise matches with the temporal and spatial boundaries of victim, crime and setting. In turn, they should be apprised of where they fit into the overall judicial process and their limits within the investigation. Consequently, each expert requires access to the factual background of the case, to the site and its contents throughout the investigation. Each forensic team member has a responsibility to influence the investigation--throughout its course when possible--to make findings within their areas of expertise, and to make these available to the rest of the team so as to contribute most meaningfully to the aims of the investigation, both forensic and humanitarian. The on-site crime scene manager has an overarching role to enable integrated access to the complete scene and its contents by each forensic expert team member. In other words, the forensic scientist is given access and the ability to influence the investigation while control of evidence from the site as to identity and criminal activity are maintained by the crime scene manager. This contribution is directed at both the crime scene manager and each forensic expert; it describes the essential spatial and temporal parameters of an expert's opinion so as to encourage cooperation, and discourage conflict, within the forensic team.

Abstract
Acute poisonings with inorganic lead compounds are exceptionally rare. In all cases of diagnosis, there are two possible sources of error: failing to recognise lead poisoning when it is present, and mistaking other diseases for lead poisoning. If exposure history is carefully taken and proper laboratory techniques are employed, the diagnosis of lead poisoning should not be difficult. In the described case of the death of a 41-year-old-man, no enzymatic disturbances characteristic of congenital erythropoietic porphyria were ascertained, and furthermore, a considerable concentration of lead was found in antemortem material, 5 months before death (blood: 1584 microg/l, urine: 531 microg/24 h). Postmortem tissue lead content in the biological material, exhumed 6 months after death, were as follows: liver, 47.6 microg/g; kidney, 4.75 microg/g; bone, 103 microg/g of sacral vertebra, 20.4 microg/g of femoral bone, 112 microg/g of pelvis; hair, 30.2 microg/g of scalp hair, 33.7 microg/g of pubic hair; nails, 13.6 microg/g. The results indicated a case of acute lead poisoning (with lead(II) oxide, as it later turned out), which manifested as acute intermittent porphyria.

Abstract
Forensic identification of human remains is composed of anthropological study of race, sex, age, etc. By using these traditional methods, inconclusive or nonidentified cases could be subjected to DNA analysis. However, in spite of advances in human identification techniques, especially by PCR-amplified DNA, some limitations that affect the ability of obtaining DNA from human remains still persist. Light microscope sections of postmortem compact bones from human remains are presented here for the purpose of increasing a forensic examiner's prediction of successful nuclear DNA typing. Femoral compact bones were obtained from 7 human remains found on the ground, in different degrees of decomposition, and were cleaned by boiling to remove soft tissues, 8 collections of bones having undergone natural decomposition, not boiled (as no soft tissue was adhered), and 5 cadavers 12 to 16 hours postmortem. The histologic sections were stained by hematoxylin and eosin, the loci CSF1PO, TPOX, TH01, F13A01, FESFPS, vWA, D16S539, D7S820, D13S317, and amelogenin were amplified by PCR, and the polyacrylamide gel was stained with silver. The results presented here clarify questions concerning the viability of DNA for identification analysis, and they also may help to establish better strategies for optimization of DNA extraction and analysis in compact bones of human remains.

Abstract
The case report of a serial killer who worked at several hospitals as a respiratory therapist is presented. The suspect was initially labeled a benevolent Angel of Death who ended the suffering of elderly patients through mercy killing. However, his subsequently declared motive for homicide was very different from other similar cases in medical settings. The application of new analysis techniques for the detection of pancuronium bromide in a series of aged exhumation tissues gave positive results and led to the resultant conviction of the therapist.

Abstract
The unique capabilities of laser ablation in combination with inductively coupled plasma sector field mass spectrometry (LA-ICP-SFMS) were employed to reconstruct details of a homicide by thallium poisoning, which took place 38 years ago in Austria. Thallium was determined in several human bone samples after acid digestion in a microwave oven. The ICP-SFMS results showed that the thallium concentration in the victim's bones was in the range 1.07-2.63 microg g(-1), which is up to 170 times higher compared to concentrations found in bones of persons who have died due to natural causes. The results were in accordance with the values obtained by graphite furnace atomic absorption spectrometry (GF-AAS). Laser ablation ICP-SFMS was applied to assess the time interval between the victim's poisoning and death. Several line scans with a laser spot size of 50 mum were performed on a thumbnail of the poisoned person and on a reference thumbnail by laser ablation ICP-SFMS. Thallium peaks were detected on the nail of the victim at a distance of 2.5 mm from the younger edge of the nail.
