Four major disasters in Aquitaine,France: use of odontologic techniques for identification

The 4 mass disasters that have affected the Aquitaine region (France) in the previous 15 years are related through the specificity and the efficiency of dental methodology in identifying the victims. The results point to the decisive influence and the efficiency of dental methodology for identification of bodies that are burned or disfigured after an accident or a prolonged period in water.     

Approaches to setting up the Center for identification of exhumed bodies in Chechen Republic

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.     

A framework for attack patterns' discovery in honeynet data

Collecting data related to Internet threats has now become a relatively common task for security researchers and network operators. However, the huge amount of raw data can rapidly overwhelm people in charge of analyzing such data sets. Systematic analysis procedures are thus needed to extract useful information from large traffic data sets in order to assist the analyst's investigations. This work describes an analysis framework specifically developed to gain insights into honeynet data. Our forensics procedure aims at finding, within an attack data set, groups of network traces sharing various kinds of similar patterns. In our exploratory data analysis, we seek to design a flexible clustering tool that can be applied in a systematic way on different feature vectors characterizing the attacks. In this paper, we illustrate the application of our method by analyzing one specific aspect of the honeynet data, i.e. the time series of the attacks. We show that clustering attack patterns with an appropriate similarity measure provides very good candidates for further in-depth investigation, which can help us to discover the plausible root causes of the underlying phenomena. The results of our clustering on time series analysis enable us to identify the activities of several worms and botnets in the collected traffic.

A study on the standard for forensic anthropologic identification of skull-image superimposition

By means of X-ray photography tests were made of 224 (100 males and 124 females) volunteer Chinese adults of Han nationality to study the related regular patterns of superimposed projection of face landmarks onto the skull. On the basis of these tests, the present article reveals from a forensic anthropology angle the related regular patterns of plane projection of the human face with its skull. Study shows that there exist a strict individual identity and exclusiveness in relation between the human face and skull. The related regularity of displacement of face landmarks appears in projection of the skull with the human head at different photographic positions and angles. On the basis of this discovery, 52 indexes in 4 groups were established as a standard for judging the identification of a skull's body origin by means of skull-image superimposition. Based on forensic anthropology, the technique has raised to a great extent the credibility of unknown skull identification. In the past 8 years, 89 unknown skulls have been identified with their body origins which provided important and accurate evidence for the solution of murders with dismembered bodies, skeletonized bodies, and unidentified dead bodies.

Insects found on a human cadaver in central Italy including the blowfly Calliphora loewi (Diptera, Calliphoridae), a new species of forensic interest

In the case of unidentified bodies the estimation of the period since death or of the season of death plays an important role to focus the attention on a reduced number of people among the ones reported missing. Forensic entomology can be one of the most important methods for these estimations, as occurred in this case. Flies are typically the first insects to colonize a dead body. The case reported here concerns the colonisation by insects of a male body in advanced decay found during the winter in Central Italy. This case is of particular interest as few data are available on the entomological evidence in the cold season. In particular, in this case we recovered Calliphora loewi (Calliphoridae), a species never collected before on dead bodies in Southern Europe. Larvae of the black soldier fly Hermetia illucens (Stratiomyidae), pupae and larvae belonging to genus Hydrothea (Muscidae), and Necrobia rufipes (Cleridae) specimens were also collected. The estimated PMI enabled identification of the cadaver, confirmed by DNA analysis.     

Implantation of radio frequency identification device (RFID) microchip in disaster victim identification (DVI)

The tsunami catastrophe of December 2004 left more than 200,000 dead. Disaster victim identification (DVI) teams were presented with the unprecedented challenge of identifying thousands of mostly markedly putrefied and partially skeletised bodies. To this end, an adequate body tagging method is essential. Conventional body bag tagging in terms of writing on body bags and placing of tags inside body bags proved unsatisfactory and problem prone due to consequences of cold storage, formalin (formaldehyde) embalming and body numbers inside storage facilities. The placement of radio frequency identification device (RFID) microchips inside victim bodies provided a practical solution to problems of body tagging and attribution in the DVI setting encountered by the Austrian DVI team in Thailand in early 2005.     

On the challenge of unambiguous identification of fentanyl analogs: Exploring measurement diversity using standard reference mass spectral libraries

Fentanyl analogs are a class of designer drugs that are particularly challenging to unambiguously identify due to the mass spectral and retention time similarities of unique compounds. In this paper, we use agglomerative hierarchical clustering to explore the measurement diversity of fentanyl analogs and better understand the challenge of unambiguous identifications using analytical techniques traditionally available to drug chemists. We consider four measurements in particular: gas chromatography retention indices, electron ionization mass spectra, electrospray ionization tandem mass spectra, and direct analysis in real time mass spectra. Our analysis demonstrates how simultaneously considering data from multiple measurement techniques increases the observable measurement diversity of fentanyl analogs, which can reduce identification ambiguity. This paper further supports the use of multiple analytical techniques to identify fentanyl analogs (among other substances), as is recommended by the Scientific Working Group for the Analysis of Seized Drugs (SWGDRUG).     

Identification of exhumed remains of fire tragedy victims using conventional methods and autosomal/Y-chromosomal short tandem repeat DNA profiling

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.     

Use of computer software for indirect molecular genetic identification of unidentified bodies

The authors discuss the development and use of computer software for realization of indirect DNA identification, based on identification of biological relation. Estimated algorithms of this method are based on regularities of parental signs inheritance by children and consist in comparative analysis of allele states of nuclear DNA typed locuses in unidentified bodies and probable parents of these dead subjects and subsequent estimation of the coefficients of the likelihood of hypotheses of their probable blood relationship. Available software maintain the database with identification characteristics of VNTR and STR locuses, HLA DQA1 locuses, and PM system (potential set of 23 locuses). The results of identification are presented as lists of exclusions and tables with estimated likelihood coefficients for the probability expert evaluation of relationship. The suggested computer-aided method of indirect identification is a new highly effective tool for personality identification by chromosome markers under conditions of mass information processing in examinations of unidentified corpses.     

Genetic relationships between blowflies (Calliphoridae) of forensic importance.

Phylogenetic relationships among blowfly (Calliphoridae) species of forensic importance are explored using DNA sequence data from the large sub-unit (lsu, 28S) ribosomal RNA (rRNA) gene, the study includes representatives of a range of calliphorid species commonly encountered in forensic analysis in Britain and Europe. The data presented provide a basis to define molecular markers, including the identification of highly informative intra-sequence regions, which may be of use in the identification of larvae for forensic entomology. Phylogenetic analysis of the sequences also provides new insights into the different evolutionary patterns apparent within the family Calliphoridae which, additionally, can provide a measure of the degree of genetic variation likely to be encountered within taxonomic groups of differing forensic utility.     

The role of mobile computed tomography in mass fatality incidents

Mobile multi-detector computed tomography (MDCT) scanners are potentially available to temporary mortuaries and can be operational within 20 min of arrival. We describe, to our knowledge, the first use of mobile MDCT for a mass fatality incident. A mobile MDCT scanner attended the disaster mortuary after a five vehicle road traffic incident. Five out of six bodies were successfully imaged by MDCT in c. 15 min per body. Subsequent full radiological analysis took c. 1 h per case. The results were compared to the autopsy examinations. We discuss the advantages and disadvantages of imaging with mobile MDCT in relation to mass fatality work, illustrating the body pathway process, and its role in the identification of the pathology, personal effects, and health and safety hazards. We propose that the adoption of a single modality of mobile MDCT could replace the current use of multiple radiological sources within a mass fatality mortuary.     

Metrological framework for selecting morphological characters to identify species and estimate developmental maturity of forensically significant insect specimens

Accurate age estimates of immature necrophagous insects associated with a human or animal body can provide evidence of how long the body has been dead. These estimates are based on species-specific details of the insects’ aging processes, and therefore require accurate species identification and developmental stage estimation. Many professionals who produce or use identified organisms as forensic evidence have little training in taxonomy or metrology, and appreciate the availability of formalized principles and standards for biological identification. Taxonomic identifications are usually most readily and economically made using categorical and qualitative morphological characters, but it may be necessary to use less convenient and potentially more ambiguous characters that are continuous and quantitative if two candidate species are closely related, or if identifying developmental stages within a species. Characters should be selected by criteria such as taxonomic specificity and metrological repeatability and relative error. We propose such a hierarchical framework, critique various measurements of immature insects, and suggest some standard approaches to determine the reliability of organismal identifications and measurements in estimating postmortem intervals. Relevant criteria for good characters include high repeatability (including low scope for ambiguity or parallax effects), pronounced discreteness, and small relative error in measurements. These same principles apply to individuation of unique objects in general.

Key points

• Metrological rigour can increase in forensic entomology by selecting measurements based on their metrological qualities.
• Selection of high-quality features for morphological identification of organisms should consider these criteria: (1) pronounced discreteness of features (minimising group overlap or maximizing interval); (2) high repeatability of assessment (such as symmetrical width rather than asymmetrical length); (3) small relative error in measurement (selecting the physically largest continuous rigid feature for measurement).
• These metrological principles also apply to individuation of unique objects in general.

THE MEDIATOR'S ASSESSMENT OF SAFETY ISSUES AND CONCERNS (MASIC): A SCREENING INTERVIEW FOR INTIMATE PARTNER VIOLENCE AND ABUSE AVAILABLE IN THE PUBLIC DOMAIN

Screening for intimate partner violence and/or abuse (IPV/A) in family mediation is important, perhaps particularly among cases without attorney representation. While most mediators agree that it is ideal to consider IPV/A in case planning, there is less agreement regarding the need to universally and systematically screen for IPV/A among all cases. Such attitudes are of concern, given research in other fields (e.g., medicine, couples therapy) and our own research in a family mediation clinic, which documents that the lack of consistent and formal IPV/A assessment results in underdetection of IPV/A. While a variety of IPV/A screening measures exist, each has shortcomings. Thus, our research and clinical experience led us to develop a new IPV/A screening measure, the Mediator's Assessment of Safety Issues and Concerns (MASIC). We discuss features of the MASIC and provide the full measure in the Appendix. The MASIC is a behaviorally specific IPV/A screen that assesses various types of abuse (e.g., coercive control, stalking, physical violence) over the course of the relationship and in the past year. It is administered as an interview to build rapport and assesses lethality indicators and offers optional recommendations for procedural changes in mediation based on IPV/A. Although we have begun relevant research, it is important to note that the MASIC has not yet been validated. Nonetheless, we recommend the use of systematic IPV/A screens in family mediation and suggest that such measures may prove especially important in providing unrepresented parties a safe and appropriate environment for mediation.

Identification and analyses of female civilian victims of the 1991 war in Croatia from the Glina and Petrinja areas

Introduction

The process of recovering and identifying human remains from individual and mass graves has proven to be the most effective method of resolving the fate of missing individuals in the former Yugoslavia. These efforts have two primary objectives: medicolegal—to identify the cause of death, and humanitarian—to bring closure to living family members, thus supporting the human rights of both the living and the deceased. From 1996 to the present, the remains of 388 individuals killed during the 1991 War in Croatia were recovered from the Glina and Petrinja areas (Sisa?ko–Moslova?ka County). The purpose of this paper is to report on the demographic and taphonomic characteristics of the recovered remains, and identify factors responsible for the discrepancy in the identification ratios.

Methods

To identify factors potentially responsible for the noted discrepancy, data were collected on the taphonomic characteristics of the recovered remains, the types of burials, as well as the factors responsible for positive identification. These factors included: forensic DNA testing, dental criteria, special signs (healed fractures, etc.), clothing and personal artifacts.

Results

The age distributions between males and females in the sample are significantly different. The mean age-at-death for males is 51.6 years, for females 67.0 years. In both sexes the majority of identifications (62.9% in females and 45.9% in males) were established through a combination of biological and non-biological features. In terms of the types of graves from which the bodies were recovered, positive identification in both sexes was lowest in mass graves (61.2% for males, and 84.2% for females). Females from mass graves were, however, better preserved than males—36.6% of males recovered from mass graves were completely skeletonized, while the same was true for only 19.3% of females (χ² = 7.06, P < 0.029). Completely skeletonized remains were identified in only 65.1% of cases, while partially skeletonized and saponified bodies were identified in 80.1% of cases.

Conclusion

Since positive identification in both sexes is strongly correlated with preservation of the bodies, the reason why female identification frequencies in the Glina and Petrinja regions are higher than male frequencies lies in the fact that females recovered from mass graves were better preserved than males recovered from mass graves. Identification of the factors responsible for this is a challenge that needs to be resolved in future studies.     

The Personal Concerns Inventory (Offender Adaptation): measuring and enhancing motivation to change

Measuring offenders' motivation for treatment is important for selection and monitoring treatment engagement, yet few psychometrically robust measures of motivation exist. The Personal Concerns Inventory (PCI) was developed to assess motivation to change in people with addictive behaviours. It focuses on identifying goals in a wide variety of life areas, and two profiles have consistently been identified--adaptive and maladaptive. This study aimed to adapt the PCI for use with offenders and assess its suitability. Following amendment, 11 men serving prison sentences were interviewed using the PCI (Offender Adaptation, OA). Personal concerns related to self-change, and partner, family, and relationships were most commonly identified. Scores suggested that offenders show adaptive and maladaptive profiles, similar to those previously identified. The PCI (OA) has promise for use with offenders, although the issue of whether the PCI (OA) is better viewed as a measure of motivation or a motivational enhancer remains for further research.
