A singular case of murder-suicide committed with a homemade firearm

The authors illustrate a peculiar case of murder-suicide committed with a homemade firearm loaded with 12-gauge cartridges (buckshot). The structure and function of this handcrafted firearm were simple but effective: an iron tube did duty as a barrel in this primitive firearm. The cartridges (modified by winding sticky tape around the external surface of the base) were inserted down one end of the tube (serving as the breech). A second iron tube with a larger diameter (so as to be able to run over each of the preloaded barrels) and with a jutting, cone-shaped metal wedge soldered to the base, was used as a rudimental firing pin. After loading the "barrel" with the modified cartridge, the gunman would ram the "firing pin" tube violently down to fire the shot. Autopsy of the woman's body showed the presence of 3 gunshot wounds caused by buckshot, while the man had a single buckshot wound in the head. Subsequent ballistic investigations enabled reconstruction of the event (typical of murder-suicide) and the functioning of the firearm, demonstrating its lethal nature, remarkably easy handling, and simplicity of production.

DNA identification of sperm cells collected and sorted by flow cytometry

In cases of rape, obtaining enough biologic material for DNA identification of the attacker is often difficult because the methods for distinguishing and separating sperm cells from vaginal cells are not sufficiently efficacious. This article describes a new, innovative method for spermatic DNA extraction from the vaginal washing fluid by means of flow cytometry. The high specificity and sensitivity of the flow-cytometric sorting method provides enough sperm cells for DNA typing. The ease of execution of this method, involving vaginal washing with physiologic solution and flow-cytometric reading of the fresh sample, substantially increases its cost-benefit ratio.     

Positional asphyxia: reflection on 2 cases

Positional asphyxia, a fatal condition arising because of the adoption of particular body positions, causing mechanical interference with pulmonary ventilation, can occur in various circumstances that are likely to come under the observation of the specialist in legal medicine (work, car accidents, torture, kidnapping, etc.). It is difficult to diagnose the cause of death in such cases because they generally present with an aspecific anatomopathologic picture. In some situations, positional asphyxia can be hard to distinguish from asphyxia because of chest compression. The main difference is in the way the event occurred: whether the particular position causing the asphyxia had been adopted by choice or by compulsion or necessity when an extrinsic mechanical action would result in traumatic asphyxia. The diagnosis of positional asphyxia is essentially based on 3 criteria: the body position must obstruct normal gas exchange, it must be impossible to move to another position, and other causes of natural or violent death must be excluded. To illustrate the main physiopathologic and diagnostic causes of positional asphyxia, the authors report 2 cases taken from the records of events that came under the observation of the Medico-Legal Sector of Bari University Hospital throughout the last 10 years.     

Population data for 12 Y-chromosome STRs in a sample from Brescia (northern Italy)

Twelve Y-chromosome STRs--DYS19, DYS389-I, DYS389-II, DYS390, DYS391, DYS392, DYS393, DYS385, DYS437, DYS438, DYS439--were typed in a population sample (n=104) of unrelated males from Brescia (northern Italy). A total of 91 haplotypes were identified by the 12 Y-STR loci. The haplotype diversity (98.68%), discrimination capacity (87.50%) and gene diversity were calculated.

A law and economics perspective on terrorism

This paper reviews the existing law and economics literature on crime, noting where various models might apply to the terror context. Specifically, it focuses on two strands of the literature, deterrence and incapacitation. It considers anti-terror measures enacted by different countries, highlighting how the details of the laws correspond to the insights from economic models of crime. In conclusion, the paper proposes an efficient sorting mechanism in which individuals will be provided with incentives to reveal their type to law enforcement authorities.     

Self‐Strangulation Through A Sphygmomanometer: An Uncommon Suicide

Suicide by asphyxia is quite a common event in forensic practice and may be implemented in different ways. The authors report a unique case of a 16‐year‐old youth who committed suicide by means of a standard mercury sphygmomanometer. This manner of suicide has never been described in the literature reviewed. A complete forensic investigation led to the conclusion that the cause of death was mechanical asphyxia, ascribed to self‐strangulation by means of an atypical item. The victim suffered from attention‐deficit/hyperactivity disorder (ADHD) syndrome and was assisted by support teachers. He had a solitary and depressive personality. The exceptional nature of this case suggests that sphygmomanometers may be regarded as possible means of self‐strangulation. The case also highlights the importance of managing patients with psychiatric or cognitive disorders; indeed, particular caution is required to keep them away from objects that, although apparently harmless, can become lethal.     

Ties that Bind: Dynamics of Group Radicalisation in Italy’s Jihadists Headed for Syria and Iraq

In recent years, thousands of radical citizens and residents from Europe have joined the so-called ‘Islamic State’ (IS) in Syria and Iraq. Unlike other European countries, Italy has traditionally been characterised by the prevalence of individual pathways of radicalisation over group mechanisms. Nevertheless, recent cases show interesting indications of the increasing role of small groups based on pre-existing personal relationships (family and friendship ties). This kind of bond can be particularly salient for IS, a jihadist “proto-state”, which needs not only ‘foreign fighters’ but also new ‘citizens’ of different sexes and ages, including entire families.
