Controversial Suicide Case Using a Submachine Gun with a Sound Suppressor—The Need of Team Work of Forensic Chemistry and Firearm Examiners

Evidence materials in a presumed suicide case were studied by a firearm examiner and a forensic chemist. The victim's body with double gunshot wounding in his forehead, a machine gun in the sustained fire mode with a silencer, and four cartridge cases were found. Examinations of the evidence, the case file studies, and experiments dedicated to the case were carried out. Relationships between the placement of cartridge cases and the gun were established using a fast camera. The distributions of gunshot residues on the evidence materials and within the comparative gunshot patterns were studied by means of optical and electron microscopy, X‐ray microanalysis, and infrared spectroscopy. The shooting distance was assessed to be 30 cm or more, whereas the greatest distance that could have been achieved by the victim himself was about 11–13 cm. The obtained results supported the version of homicide rather than suicide.     

A Fatal Shot with a Signal Flare—A Crime Reconstruction*

Abstract: A reconstruction of an incident of a fatal wounding of a football fan with a parachute flare was performed. Physical and chemical examinations of the victim’s trousers and parts of a flare removed from the wound in his leg were performed by means of an optical microscope and a scanning electron microscope coupled with an energy dispersive X‐ray spectrometer. Signs of burning were seen on the front upper part of the trousers, including a 35–40 mm circular hole with melted and charred edges. Postblast residue present on the surface of the trousers contained strontium, magnesium, potassium, and chlorine. Also the case files—the medical reports and the witnesses’ testimonies—were thoroughly studied. It has been found that the evidence collected in the case supported the version of the victim being shot by another person from a distance.     

There's more to it than data protection – Fundamental rights,privacy and the personal/household exemption in the digital age

Heated debates triggered by the plans to introduce the “right to be forgotten” exposed problems the all-encompassing application of rules on data processing may cause in practice. The purpose of this article is to discuss the compatibility of these rules with the rapidly evolving online environment in the context of the need to guarantee human rights on the internet. The author argues that there is an imbalance in the protection of individual rights online. It results from the limited application of personal/household exception and, in general, the narrow understanding of the concept of online privacy. According to the author in order for data protection laws to flesh out not only the fundamental right of data protection, but also play a mediatory role in balancing other rights, the application of the personal/household exception should be extended to include private online activities. This would reflect the complex character of the very concept of online privacy, diversity of actors and activities shaping online “territories”, as well as the increasingly heterogeneous fabric of the Web.     

Anti-immigrant Attitudes in Russia: The Group Position Model Reconsidered

Abstract

This article analyses the relationship between relative group position in an ethnically stratified social order and anti-immigrant attitudes in Russia. Based on data from the Russia Longitudinal Monitoring Survey of the Higher School of Economics, it studies the role of two objective indicators of group position: relative ingroup size and the group’s dominant political status within a region. The findings show that when a group position is measured in numerical terms, the attitudes of ethnic Russians seem to follow social dominance theory, while titulars tend to conform to the alienation-based extension to the group position model.     

Grouping of ammunition types by means of frequencies of occurrence of GSR

An attempt was made to build a classification scheme for gunshot residues (GSR) samples originating from four types of ammunition, collected from shooters' hands immediately after shooting. The secured material was examined with the use of SEM-EDX method in the automatic manner. The obtained results were expressed as frequencies of occurrence of particles assigned to various chemical classes. In order to establish the most discriminative of these features the Mann-Whitney test was performed. Cluster analysis was performed for grouping the analysed samples according to their origin, i.e. the type of ammunition. It has been found that samples of GSR originating from Browning 7.65 mm and Luger 9 mm ammunition can be fairly easy differentiated from the remaining samples, whereas samples of GSR originating from of Makarov 9 mm and these of Tokarev 7.62 mm could not be differentiated using frequencies of occurrence of particles in the selected chemical classes.     

Sacred or Secular? ‘Memorial’, the Russian Orthodox Church,and the Contested Commemoration of Soviet Repressions

The reconstruction of the history from the late 1980s to the mid-1990s of Soviet repressions critically influenced the social formation of Gulag memory in Russia. Amongst those re-narrating the past, the ‘Memorial’ Society and the Russian Orthodox Church most actively shaped the collective memory of Soviet repressions, trying to establish multi-layered explanatory constructs of the Gulag. Their interpretations were crystallised through contemporary memorialisation acts in significant landscapes of the past. Focusing on Solovki, Ekaterinburg, Butovo and Magadan, and analysing tensions in their memorialisation processes, we discuss secular and Orthodox interpretations of the Gulag, and their impact on the memory of the Soviet repressions in contemporary Russia.     

Variation of the chemical contents and morphology of gunshot residue in the surroundings of the shooting pistol as a potential contribution to a shooting incidence reconstruction

A study of the chemical contents and sizes of gunshot residue originating from 9×18mm PM ammunition, depositing in the vicinity of the shooting person was performed by means of scanning electron microscopy and energy dispersive X-ray spectrometry. Samples of the residue were collected from targets placed at various distances in the range 0-100cm as well as from hands and clothing of the shooting person. Targets were covered by fragments of white cotton fabric or black bovine leather. In the case of cotton targets microtraces were collected from circles of 5 and 10cm in radius. Results of the examinations in the form of numbers of particles, proportions of their chemical classes and dimensions revealed a dependence on the distance from the gun muzzle, both in the direction of shooting and in the opposite one, i.e., on the shooting person. The parameters describing gunshot residue differed also depending on the kind of the target substrate. The kind of obtained information gives rise to understanding the general rules of the dispersion of gunshot residue in the surroundings of the shooting gun. Thus, it may be utilised in the reconstruction of shooting incidences, especially in establishing the mutual positions of the shooter and other participants of the incident.
