Guidelines for the recognition of cemetery remains in Greece

Forensic pathologists frequently consult anthropologists for the identification of skeletonized human remains. These remains may be the result of criminal activity or remains that were unearthed because of erosion, or during construction projects. In some cases, human remains that had been previously buried in a cemetery may be the subject of a forensic investigation. Early recognition of cemetery remains prevents unnecessary efforts and conserves precious resources. One of the key characteristics of cemetery remains is the presence of embalmed tissue. However, there are countries where embalming is not a common practice, and other clues must be sought for identifying previously buried remains. Current funerary customs in Greece and, in particular, the tradition of exhumations result in a large number of misplaced human remains. The present study presents examples of cemetery remains from Greece and offers guidelines for recognizing changes on skeletal remains that may be indicative of a cemetery origin. Location of discovery, condition of the remains, and the types of associated artifacts are all factors that aid forensic anthropologists in identifying cemetery remains.     

Recognition of cemetery remains in a forensic context

The purpose of this paper is to provide guidelines for the recognition of human remains from modem and historic cemeteries found in a forensic context. Three avenues of evidence may be pursued to confirm the origin of cemetery remains: context, condition of the body, and associated artifacts. This article outlines types of North American cemeteries, demonstrating how land use over time has resulted in many being closed, moved, or forgotten, leaving only the context to indicate their presence. The condition of human cemetery remains varies considerably depending on cultural practices and burial environment, but many exhibit combinations of the following traits: dried or embalmed tissue; erosion of bony pressure points; cortical bone flaking; and bone damage due to autopsy or embalming. Examples of artifact types useful in recognizing cemetery remains are also provided. Two cases from British Columbia, Canada are presented to demonstrate the diagnostic features of a disturbed cemetery burial.     

Taphonomic Patterning of Cemetery Remains Received at the Office of the Chief Medical Examiner,Boston, Massachusetts

A sample of 49 cases of cemetery remains received at the Office of the Chief Medical Examiner, Massachusetts (OCME‐MA), in Boston was compared with published taphonomic profiles of cemetery remains. The present sample is composed of a cross section of typical cases in this region that ultimately are derived from modern to historical coffin burials and get turned over to or seized by law enforcement. The present sample was composed of a large portion of isolated remains, and most were completely skeletonized. The most prevalent taphonomic characteristics included uniform staining (77.6%), coffin wear (46.9%), and cortical Exfoliation (49.0%). Other taphonomic changes occurring due to later surface exposure of cemetery remains included subaerial weathering, animal gnawing, algae formation, and excavation marks. A case of one set of skeletal remains associated with coffin artifacts and cemetery offerings that was recovered from transported cemetery fill is also presented.     

Postmortem Aortic Dissection: An Artifact of the Embalming Process

Aortic dissection (AD) is a serious condition that affects 3/100,000 individuals a year. Recently, a case report was published describing an embalmed patient with an aortic dissection. The purpose of this study was to examine the frequency of AD among 80 embalmed cadavers and confirm the AD with histopathologic evaluation. In seven cases of grossly identified AD, six were determined to be due to the embalming procedure and only one case of true antemortem AD was confirmed. These results suggest that aortic morphology can be altered by administration of the embalming fluid and that alterations can mimic AD, not only on gross inspection but also on postmortem imaging. Awareness of this embalming artifact may prevent misdiagnosis of an aortic dissection in an embalmed patient, a point particularly useful for autopsy pathology that may include postmortem examination of an embalmed patient.     

Ultrastructural and immunofluorescent detection of herpes simplex virus after embalming and burial

The practice of embalming preserves body tissues, and embalmed bodies may resist decay processes for many decades with relatively little change. As the chemicals used for embalming are poisonous to microorganisms, bacterial and viral cultures are futile after such funerary procedures are performed. However, embalming may act as a virtual tissue fixative, especially with arterial perfusion, and identification methods other than culture may be used to detect and identify pathogenic organisms. In the case presented here, a death from a fulminating, but unidentified, illness in a young girl was successfully diagnosed as herpes hepatitis by immunofluorescent and electron-microscopic studies of tissue obtained 3 weeks after she was embalmed and interred. Routine embalming and burial should not eliminate these diagnostic procedures from consideration in specific situations where potentially useful information may be realized.     

The postmortem fate of Pat Gregory: a disinterred Native American

In late June 1990, the Mono County Sheriffs Department in Bridgeport, CA contacted the Physical Anthropology Human Identification Laboratory (PAHIL) at California State University, Chico to seek assistance in the identification of a recently discovered skull. To assist with possible identification, the cranium received a classic physical anthropological/morphological analysis to suggest the decedent's sex, age at death, ancestral affiliation, and uniqueness. It was concluded the cranium was that of an older male, and someone with mixed ancestry, probably Native American/White. Suggested uniquenesses were an eroded and greasy texture, with adhering white sand, evidence of healed antemortem nasal fractures, and a bifid left occipital condyle. The cranium was confiscated from a man suspected of vandalizing a Native American cemetery just south of the community of Lee Vining. The cemetery was established in the mid-1800's by local Native American tribes. Although ownership of the land was disputed by the US Forest Service (the Inyo National Forest), and the Los Angeles Department of Water and Power (LADWP), county authorities claimed that because the incident involved the desecration of a cemetery and human remains, it was a legal issue, and therefore, the Sheriff's Department had jurisdiction over the case if not the land. The suspect pled guilty to the possession of Native American remains but claimed not to have desecrated a grave. Over the next year and a half, members of the Native American community representing various tribes sought the return of the cranium, while also seeking assurance that it belonged to the vandalized grave. While county, US Forest Service, and LADWP officials continued to argue over whom had jurisdiction of the remains the superior court judge ordered the county to pay for any analysis necessary to determine if the cranium belonged to the decedent in question. This report addresses the conclusions of that analysis and the disposition of the case. Furthermore, the report addresses the forensic value to Native Americans of the continued study of a wide variety of human skeletal remains.     

Detection of ketosis in vitreous at autopsy after embalming

Ketosis occurs in ketoacidosis or malnourishment. When either is suspected in relation to a death, it may be important to analyze for ketosis at autopsy. We encountered a case where starvation was suspected in a deceased nursing home resident, where the body had been embalmed prior to autopsy. Gas chromatography (GC) was unable to separate acetone from formaldehyde, a component of embalming fluid. The Acetest is a simple test that can detect acetone and acetoacetate in body fluids. We validated the Acetest with GC on vitreous. The Acetest and GC were consistent except at very low levels of acetone or acetoacetate. The sensitivity of the Acetest for acetoacetate in vitreous was 10 mg/dL, consistent with early starvation. Significant interference from embalming fluid did not occur. The Acetest was negative in the described case. The Acetest is a simple and useful test for the detection of ketosis in embalmed autopsies.     

Factors affecting postmortem tooth loss

Unassociated human bones are a particular problem during the exhumation of mass graves and a factor that limits anthropological and paleopathological analyses from archaeological contexts. Extensive anthropological literature has focused on the complex taphonomic factors that influences bone assemblages, but little attention has been paid to postmortem tooth loss and factors affecting this process. The following study focuses upon the influence of different factors on postmortem tooth loss. Three samples were investigated in the study: a medieval church cemetery containing 110 individual skeletal remains, and two samples from a series of mass graves made within the same time period in 1999, containing 402 bodies. The frequency of postmortem tooth loss was analyzed relative to postmortem interval for each sample, excavation methods, age distribution, and presence of bone loss associated with periodontal disease. Our results indicate that the degree of alveolar bone loss significantly affected both antemortem and postmortem tooth loss and that the frequency of postmortem tooth loss has the strongest correlation to time since death. These findings suggest that additional care should be taken when exhuming remains from older contexts.     

Analyzing and Interpreting Lime Burials from the Spanish Civil War (1936–1939): A Case Study from La Carcavilla Cemetery

Over 500 victims of the Spanish Civil War (1936–1939) were buried in the cemetery of La Carcavilla (Palencia, Spain). White material, observed in several burials, was analyzed with Raman spectroscopy and powder XRD, and confirmed to be lime. Archaeological findings at La Carcavilla's cemetery show that the application of lime was used in an organized way, mostly associated with coffinless interments of victims of Francoist repression. In burials with a lime cast, observations made it possible to draw conclusions regarding the presence of soft tissue at the moment of deposition, the sequence of events, and the presence of clothing and other evidence. This study illustrates the importance of analyzing a burial within the depositional environment and taphonomic context.     

The influence of storage temperature and chemical preservation on the stability of succinylcholine in canine tissue

Succinylcholine (SCh) has been detected six months postmortem in liver, kidney, and injection site muscle of rats given 10 to 200 mg/kg by intramuscular injection. SCh stability was studied in canine tissue to evaluate three storage temperatures and two chemical preservatives at three time periods after injection. Nine mongrel dogs weighing 17.2 to 28 kg were divided equally into three groups and administered either 0.5, 1.0, or 5.0 mg SCh/kg intravenously into the cephalic vein. Liver, kidney, and gastrocnemius muscle were removed 90 min post-injection and divided into twelve portions. Each portion was treated with embalming fluid, physostigmine, the combination (50/50), or nothing. Chemically treated tissues and nontreated tissues were then stored at either 27, 5, or -20 degrees C for a period of up to forty days. Tissue portions were analyzed using ion-pair extraction, chemical demethylation, and gas chromatography with nitrogen phosphorous detection. Stability of SCh was greatest for samples stored at -20 degrees C and preserved with the combination of embalming fluid plus physostigmine. Kidney concentrations of SCh were significantly higher than those in liver or muscle at all doses. SCh was detected 24 h post-injection in all cases. By 40 days, only trace amounts of SCh, if any, could be detected in samples stored at room temperature with no chemical preservatives.     

Identification of the cadaver remains of Josef Mengele

In 1985 at the cemetery in Embu near Sao Paulo, Brazil, parts of a skeleton were exhumed, and now these parts have been examined to determine whether they are the remains of the corpse of Dr. Josef Mengele, the camp doctor of the Auschwitz concentration camp. The osteometrical and osteological findings ascertained correspond completely and consistently without contradiction with all the available personal data of Josef Mengele. Through a method of electronic visual mixing for the identification of the skull, it was determined that all the authentic pictures available used for comparison correspond definitely and consistently to the exhumed skull.     

Identification of the cadaveric remains of Josef Mengele

Application of mtDNA sequence analysis in forensic casework for the identification of human remains

In four forensic cases of unidentified skeletal remains investigated in the last year, we were able to attach three to missing persons. In one case we could show that the discovered bone sample did not fit to a missing child. The method for mitochondrial DNA analysis for the routine identification of skeletal remains was established in our institute by typing bone samples of defined age obtained from Frankfurt's cemetery. Reproducible results were obtained for bones up to 75 years old. For analysis the bone samples were pulverised to fine powder, decalcified and DNA was extracted. From the DNA we amplified a 404-bp fragment from HV-1 and a 379-bp fragment from HV-2 of the mtDNA control region. After sequencing of the PCR products, the results were compared to the Anderson reference sequence and to putative maternal relatives.     

Head injuries of Roman gladiators

Gladiator remains from a recently unearthed cemetery in ancient Ephesus (Turkey) offer a unique opportunity for proving common theories involving the weaponry and techniques of gladiator fighting based on the evidence supplied by cranial bones. This mass grave is the first of its kind to undergo a thorough osteological and forensic examination. A minimum number of individuals (MNI) analyses revealed that at least 68 individuals. All individuals found turned out to have been males aged between 20 and 30 years, except for one female associated with a female slave gravestone, and one male aged 45-55 years, had been buried in this area of the cemetery. The male mean body height was 168 cm (S.D.=5 cm), which lies inside the normal range of height for Roman populations at those times. Eleven (16% of MNI) individuals exhibit a total of 16 well-healed antemortal cranial traumata. Five of the 11 individuals showed multiple trauma. Ten (15% of MNI) individuals exhibited a total of 10 perimortal cranial traumata. This is a surprisingly high frequency of deadly head injuries, taking into account that most of the gladiator types wore helmets. A possible explanation could be the frequently reported deathblow technique used by the hammer-carrying death god "Dis Pater". The gladiator weaponry is well known through historical sources. At least one injury per known type of offensive weapon could be identified, as well as evidence for the most popular, the gladiator trident, which was found to be represented by one perimortem and two antemortem injuries. Overall the reportedly very strict nature of combat rules for gladiator fights could be confirmed by the absence of multiple perimortal traumatized individuals, showing a lack of the excessive violence commonly observed on medieval battle ground victims. This graveyard gives the opportunity to confirm historical aspects and to check the reliability of forensic methods for identification of antemortem, perimortem, or postmortem bone lesions. Typical examples for these kinds of lesions and injuries are presented. The colour of the margins of the traumata proved to be the most distinguishing feature for postmortal lesions.     

The identification of Josef Mengele. A triumph of international cooperation

In recent weeks, world attention has been focused on the identification of skeletal remains suspected of being those of the most widely sought Nazi war criminal still at large--Josef Mengele. Several important turns in the investigation of his whereabouts led to a small city south of S?o Paulo, where he had been living until 1979. Mengele was reported to have drowned and to have been buried in a country cemetery near his last residence. The initial processing of the remains was done at the Medicolegal Institute of S?o Paulo by police officials in consultation with anthropologists and dentists as well as Dr. Wilmes Teixeira of Mogi das Cruzes, a suburb of S?o Paulo. Dr. Teixeira coordinated the team of authorized international forensic experts officially representing the governments of West Germany and the United States, as well as the Simon Wiesenthal Center of Los Angeles, who joined Brazilian scientists in completing identification. The success of the investigation was due to complete cooperation among members of the team, resulting in verification, within a reasonable scientific certainty, that these were the remains of Josef Mengele.     

Postmortem tissue embolisms. Report of 3 cases

In three cases of autopsy (cause of death - intoxication and drowning) we found in the lung intraalveolar und intravasal lymphatic tissue and bone-marrow. The results cannot be explained with violence during lifetime, but in tow cases as an effect of fracture of rips caused by external cardiacmassage, in one case by embalming with injection of conservation fluids.

Genetic Identification of Communist Crimes’ Victims (1944–1956) Based on the Analysis of One of Many Mass Graves Discovered on the Powazki Military Cemetery in Warsaw,Poland

As the result of the communist terror in Poland, during years 1944–1956 more than 50,000 people died. Their bodies were buried secretly, and most places are still unknown. The research presents the results of identification of people buried in one of many mass graves, which were found at the cemetery Pow?zki Military in Warsaw, Poland. Exhumation revealed the remains of eight people, among which seven were identified genetically. Well‐preserved molars were used for the study. Reference material was collected from the closest living relatives. In one case, an exhumation of victim's parents had to be performed. DNA from swabs was extracted with a PrepFiler^® BTA Forensic DNA Extraction Kit and organic method. Autosomal, Y‐STR amplification, and mtDNA sequencing were performed. The biostatistical calculations resulted in LR values from 1608 to 928 × 10¹⁸. So far, remains of more than 50 victims were identified.     

DNA Identification of Commingled Human Remains from the Cemetery Relocated by Flooding in Central Bosnia and Herzegovina

The floods in Bosnia and Herzegovina in May 2014 caused landslides all over the country. In the small village of ?eri?i, near the town of Zenica, a landslide destroyed the local cemetery, relocated graves, and commingled skeletal remains. As the use of other physical methods of identification (facial recognition, fingerprint analysis, dental analysis, etc.) was not possible, DNA analysis was applied. DNA was isolated from 20 skeletal remains (bone and tooth samples) and six reference samples (blood from living relatives) and amplified using PowerPlex^® Fusion and PowerPlex^®Y23 kits. DNA profiles were generated for all reference samples and 17 skeletal remains. A statistical analysis (calculation of paternity, maternity, and sibling indexes and matching probabilities) resulted in 10 positive identifications. In this study, 5 individuals were identified based on one reference sample. This has once again demonstrated the significance of DNA analysis in resolving the most complicated cases, such as the identification of commingled human skeletal remains.     

The Applicability of the Lamendin Method to Skeletal Remains Buried for a 16-Year Period: A Cautionary Note

The Lamendin method is widely reported as one of the most reliable means of age estimation of skeletal remains, but very little is known concerning the influence of burial in soil. This study aimed at verifying the reliability of the Lamendin method on corpses buried for 16 years in a cemetery. The Lamendin and the Prince and Ubelaker methods were applied. In all age groups except the 40- to 49-year–olds, the error was higher in the buried sample. The age-at-death error ranged between 10.7 and 36.8 years for the Lamendin method (vs. the reported 7.3–18.9 years) and 9.5 and 35.7 for the Prince and Ubelaker one (vs. the original 5.2–32.6 years); in all age groups, the error is closer to that found on archeological populations. These results suggest caution in applying the Lamendin method to forensic cases of human remains buried even for a brief period under soil.
