Characteristic Features of Pediatric Firearm Fatalities—Comparisons Between Australia and the United States

Abstract:  Gunshot deaths in children less than 17 years of age from Adelaide, SA, Australia (1969–2005) and from San Diego County, CA, United States (1988–2005) were compared. Forty-two pediatric gunshot fatalities occurred in South Australia (1.1 cases/year; M:F = 30:12). There were 6 accidents (14%), 14 suicides (33%), and 22 homicides (52%). In San Diego there were 185 cases ( c. 10 cases/year; M:F = 148:37). There were 6 accidents (3%), 42 suicides (23%), 130 homicides (70%), and 7 undetermined cases (4%). The incidence of homicide was significantly higher in San Diego County compared to Adelaide ( p  < 0.001), with a higher proportion of murder–suicides occurring in Adelaide. There were markedly more accidents and suicides involving males in Adelaide and a far higher number of male homicide victims in San Diego County compared to females. Rifles of 0.22-caliber were preferred weapons in South Australia, compared to handguns in San Diego County.     

Six‐Year Retrospective Study of Suicidal Hangings: Determination of the Pattern of Limb Lesions Induced by Body Responses to Asphyxia by Hanging*

Abstract: The objective of the present study was to estimate the proportion of hanging victims presenting with limb lesions, to compare this rate between hanging in restraint spaces and in more open settings, and to describe the usual pattern of limb lesions associated with hanging. Two hundred and seven cases of suicidal hanging were retrospectively reviewed and compared to 45 homicidal nonhanging strangulation victims. Bruises incidence was significantly lower in hanging victims (19.8%) compared to homicidal strangulation victims (55.6%). Bruises were more commonly encountered in restraint areas such as closets and staircases (56.3% and 66.7%, respectively) than in more open settings such as barn, bridge, fence, and park. Limb bruises on hanging victims were generally located on the posterior upper limb or the anterior lower limbs, whereas strangulation victims did not display this preferential bruises concentration. Possible suspicion criteria for limb bruises distribution are discussed, in relation to physiopathology of human asphyxia by hanging.     

Characterization of lesions in hanging deaths

Hanging is a common method of committing suicide and a routine task in medico-legal autopsies. The hanging mark is the most relevant external sign and its characteristics are well known, but, for unknown reasons, there are major differences in reports on internal findings. We retrospectively studied 228 consecutive cases of hanging deaths. A complete standard autopsy was performed for every case. We investigated the association between the characteristics of the hanging mark and the frequency of bone, cartilage, soft tissue, and vascular injuries with the mode of suspension. Most cases (75.3%) presented some kind of bone or cartilage fracture, but these were unrelated to any of the variables studied. Vascular lesions are clearly more infrequent: intimal injuries were found in the carotid artery (9.1%), the jugular vein (2.2%), and ruptures of the carotid adventitial layer (21.7%). These could be partially associated with the use of a hard fixed noose and body weight.     

Criminological and Medico-legal Aspects in Homicidal and Suicidal Sharp Force Fatalities

The interpretation of sharp force fatality dynamics may be difficult in some cases, but a contribution to analysis of the phenomenon may be provided by case studies. Therefore, the purpose of our study is focused on identifying, in observed sharp force fatalities, reliable parameters that can differentiate a homicidal and suicidal manner of death, with particular reference to criminological parameters. Data derived from sharp force fatality cases in Padua and Venice from 1997 to 2019, anonymized and collected in Excel, included personal, circumstantial, clinical, and psychopathological–criminological data, as well as crime scene investigation, necroscopic, and toxicological data. Statistical analyses were performed using chi-square and Wilcoxon rank-sum tests. Possible predictors of homicide were analyzed by logistic regression. Six parameters (bloodstains distant from the body, clothing lacerations, hesitation/defense wounds, number of injuries, and potential motives) were significantly different in the two groups (p < 0.05). An independent statistical association between potential motives explaining the crime (p < 0.001; OR 27.533) and homicide on multiple logistic regression analysis was highlighted. The absence of clothing lacerations was inversely related to homicide (p = 0.002, OR 0.092). To the best of our knowledge, this is one of very few Italian studies concerning the differential diagnosis between homicidal and suicidal sharp force fatalities. The dynamics of the event is established in most cases by the integrated evaluation of data from crime scene investigation and the autopsy. Nevertheless, in an atypical scenario, a psychopathological–criminological analysis may provide essential elements, and particular attention should be given to the identification of potential explanatory motives.     

Correlations Among the HLA-DQB1 Alleles and Suicidal Behavior

Suicide is a worldwide health problem with multiple causes, including genetic factors. The major histocompatibility complex (MHC) is represented by an assembly of gene encoding the human leukocyte antigen (HLA). The purpose of our study was to determine associations between the HLA profiles and predisposition for suicidal behavior. We harvested blood samples from persons with history of suicidal attempts (case group) and persons never exhibiting such behavior (control group). The DNA was extracted and amplified via polymerase chain reaction (PCR) to determine the HLA-DQB1 profiles. Statistical data processing was performed with the Epi Info program. We found that the presence of the HLA-DQB1*02 allele increases the risk of suicidal behavior, while HLA-DQB1*05 alleviates such risk. The genotype that presented the most increased risk for suicidal behavior was found to be HLA-DQB1*02/HLA-DQB1*03. Our study has demonstrated the presence of several associations between HLA profiles and suicidal behavior.     

“New Terrorism” = Higher Brutality? An Empirical Test of the “Brutalization Thesis”

This article focuses on the so-called “brutalization” of terrorism. The brutalization thesis as part of the larger theoretical concept of “new terrorism” argues that “new terrorism” is more brutal than “old terrorism.” Many scholars claim that the 9/11 attacks mark the beginning of a new era of terrorism that has lifted international as well as domestic terrorism to a new level of violent brutality. Others argue that this process had already started in the early 1990s. After discussing possible ways to operationalize a brutalization of terrorism, for example focusing on suicide bombings or terrorist attacks against soft targets, this article tests the empirical credibility of the brutalization thesis regarding both potential starting points. Data from the Global Terrorism Database (GTD) shows that only three out of nine indicators increased significantly during the 1990s, partially backing the idea of a general brutalization, whereas increasing numbers of suicide attacks and beheadings after 9/11 support the notion of a qualitative change in terrorism and its brutality connected with the idea of maximizing media and public attention. Yet, these developments are regionally limited and the brutality of this “new terrorism” exceeds the levels known from the zenith of “old terrorism” in the 1970s and 1980s in only a few cases.     

Competing to Kill: Terrorist Organizations Versus Lone Wolf Terrorists

Are organizationally linked suicide attacks deadlier than those launched by lone wolf terrorists? This article elaborates a perpetrator-based distinction among suicide terrorist attacks between organizations and lone wolf terrorists, who operate in the absence of a financially or physically supportive terrorist organization. The expectation is that terrorist organizations would serve as commitment tools that increase the loyalty of suicide bombers to their missions through material and non-material incentives. Findings demonstrate that when terrorist organizations are involved in the planning and execution of suicide terrorist attacks, not only do they increase the lethality of these attacks but they also accentuate the tactical advantages of suicide terrorism. These findings suggest that despite the recent upsurge and concern about lone wolf terrorism, the lethality and security impacts of suicide terrorism continue to be driven by terrorist organizations.     

A Response to Yang,Burrola, and Bryan: Suicide Ideation among Participants in an After-School Program: A Convenience Sample

The exploratory study conducted by Yang, Burrola, and Bryan (2009) provides an excellent platform for calling attention to the issue of suicide risk among elementary and middle school youth. Using their study as a catalyst, with this commentary I consider the finding that 12% of the young people surveyed acknowledged that they had “seriously considered suicide during the past year.” I offer an alternative interpretation that focuses more explicitly on youth resilience and discuss how youth organizations can become more intentional and proactive in their overall suicide prevention aims.     

Genetic analysis of suicide: a sample study in Tuscany (Central Italy)

Many studies have examined the genetic contribution to suicide. However, data on suicide in the Italian population are scarce. We therefore aimed to address this gap by investigating a cohort of 111 Italians for whom a verdict of suicide had been declared in court in Florence, Italy between 2007 and 2017. This cohort included 86 men and 25 women. DNA samples were obtained from tissues or blood, and 22 genes from multiple neurobiological pathways previously shown to be associated with the pathogenesis of suicide were analysed. Next-generation sequencing was used to compare these gene sequences with those from a large, normal population. In this study, we identified 19 gene variants that were present at significantly lower frequencies in our Italian cohort than in the general population. In addition, four missense mutations were identified in four different genes: Monoamine Oxidase A (MAOA), 5-Hydroxytryptamine Receptor 2 A (HTR2A), Sodium Voltage-Gated Channel Alpha Subunit 8 (SCN8A), and Nitric Oxide Synthase 3 (NOS3). Our study identified several potential genetic links with suicide in a cohort of Italians and supports a relationship between specific genetic variants and suicidal behaviour in this population.
