Suicide by shooting is correlated to rate of gun licenses in Austrian counties

[Forensic aspects of gunshot suicides in Germany]

Suicidal gunshot wounds are a common appearance in forensic casework. The main task of the coroner lies in the detection of typical pathomorphological correlates, thus differentiating between homicide, suicide and accident. Apart from characteristic bloodstain patterns on the gun and shooting hand, the localisation of the entrance wound and the position of the weapon, additional details such as family background or medical history are important aspects of forensic investigation. An uncommon choice of weaponry and its unusual morphological manifestation often complicate the examination and reconstruction of such cases. Furthermore, due to social stigmatisation, the possibility of secondary changes by relatives at the crime scene should be considered. In addition to autopsy findings, a careful crime scene investigation and bloodstain pattern analysis, a ballistic reconstruction can be an essential tool to gain knowledge of the shooting distance and position of the gun.

Recent firing range suicides in South Australia

Two cases are reported from South Australia, where deaths occurred that were due to single self-inflicted gunshot wounds to the head in individuals who were visiting indoor firearm ranges. Case 1: A 54-year-old man visiting an indoor firing range placed a .357 magnum handgun to his head and fired one shot. Case 2: A 23-year-old woman who was being instructed in firearm usage at an indoor firing range placed a 9 mm handgun to her head and fired one shot. In both cases, deaths were due to cerebral laceration with skull fracture. Firing ranges may be utilized by individuals who are seeking weapons for suicide attempts, and suicide may be successfully undertaken at such locations even while a victim is under direct supervision. In jurisdictions, where firearm ownership is strictly legislated, it may be that clubs can inadvertently provide access to firearms for this type of activity.

Characteristics of police officer suicides in the Federal Austrian Police Corps

BACKGROUND

Suicide rates among police officers may be high because of strong occupational stressors.

AIMS

This study examined the suicide rate and suicide characteristics among police officers in the Federal Austrian Police Force.

METHODS

All suicides among policemen during the period 1996-2006 were analyzed retrospectively on the basis of personalized police record files from all Austrian police departments. Information on sex, age, marital status, children, region, method and place of suicide, suicide notes, position, and length of service was extracted from these files. The general Austrian population, adjusted for sex and age composition, served as the comparison group.

RESULTS

The suicide rate among male police officers was 30.2/100,000 (SD 11.0), which was comparable to the suicide rate in the adjusted general population (30.5/100,000; SD 2.9). The female police officer suicide rate was 1.8/100,000, while the corresponding suicide rate of the adjusted female general population was 12.5/100,000 (SD 1.7). Firearms were the most frequent suicide method (77.8%), and the incidence of suicide notes was 30.8%.

CONCLUSIONS

Suicide rates among police officers seem comparable to those of the age-adjusted general population. Given the healthy-worker effect, these results still suggest an increased risk of suicide among police officers. These findings should stimulate further research on stressors and risk factors for suicide among officers and should also encourage departments to increase awareness regarding suicidal signs among officers.

Child and adolescent suicides in Bosnia and Herzegovina before and after the war (1992-1995)

BACKGROUND

Evidence on youth suicides from Southeastern Europe is scarce. We are not aware of previous reports from Bosnia and Herzegovina, which experienced war from 1992 to 1995. Durkheim's theory of suicide predicts decreased suicide rates in wartime and increased rates afterward.

AIMS

To compare child and adolescent suicides in Bosnia and Herzegovina before and after the war.

METHODS

Data on youth suicide for prewar (1986-90) and postwar (2002-06) periods were analyzed with respect to prevalence, sex and age differences, and suicide methods. Suicide data from 1991 through 2001 were not available.

RESULTS

Overall youth suicide rates were one-third lower in the postwar than in the prewar period. This effect was most pronounced for girls, whose postwar suicide rates almost halved, and for 15-19-year-old boys, whose rates decreased by about a one-fourth. Suicides increased among boys aged 14 or younger. Firearm suicides almost doubled proportionally and were the predominant postwar method, while the most common prewar method had been hanging.

CONCLUSIONS

The findings from this study indicate the need for public education in Bosnia and Herzegovina on the role of firearm accessibility in youth suicide and for instructions on safe storage in households. Moreover, raising societal awareness about suicide risk factors and suicide prevention is needed.

Firearms, Hanging, and Drowning Suicides in the Republic of Ireland

Background: The firearms climate in Ireland is rapidly changing, and there is currently no research on the risk profiles of those dying through firearms suicides. Aims: To compare the sociodemographic profile of firearms suicide deaths with hanging and drowning suicides. Methods: Analyses are based on data for 9,674 suicides that occurred between 1980 and 2005 and provided by the Central Statistics Office of Ireland (CSO). Risk factors included were gender, place of residence, employment status (agri-employed/not agri-employed), marital status, and age. Results: Those dying by shooting were twice as likely to be male than those dying by hanging (95% CI = 1.5 to 2.6) and 6.7 times more likely than those dying by drowning (95% CI = 4.9 to 9.1). They were also more likely to have resided in a rural location (hanging OR = 3.8, 95% CI = 2.8 to 5.0; drowning OR = 4.2, 95% CI = 3.1 to 5.6) and to have been agri-employed (hanging OR = 1.3, 95% CI = 1.1 to 1.6; drowning OR = 1.4, 95% CI = 1.1 to 1.7). Firearms suicides were significantly younger (H = 458.9, p < .0005). Model fit statistics from logistic regressions are presented. Factors included in the study were limited to those recorded by the CSO. Conclusions: The findings have implications for awareness training for suicide prevention workers and for those concerned with Ireland’s increasingly liberal firearms climate.

Firearm-assisted suicide: legislative, policing and clinical concerns

Until recent years the Republic of Ireland had one of the most restrictive regimes on firearms access with the Irish police (An Garda Siochana) consistently refusing to grant certificates for a wide range of guns including handguns, high calibre rifles and shotguns capable of holding more than three cartridges. In 2004 the High Court ruled that this policy was without legislative backing and since then the police began to issue certificates for firearms where the applicant is not disentitled under law from possessing a gun. Set against this backdrop, this paper explores the consequences of liberal gun regimes in the context of access to firearms by those suffering from mental illness and who pose a threat of parasuicide or suicide. Consideration is given to experiences in other jurisdictions and international research on firearm suicide prevention. Finally some recommendations for changes in legislation, policy and protocol in the Irish context are presented.

Rural-urban differences in Austrian suicides

OBJECTIVES

The answer to the question whether suicide rates are higher in urban than in rural areas may have changed over the years. This study analyzes the longitudinal trends of rural and urban suicides in Austria from 1970 to 2005. The most recent decade, 1995-2005 was also investigated cross-sectionally in terms of age groups, gender, suicide methods and family status.

METHODS

Official suicide statistics were calculated in a Poisson regression model to determine trends in suicide rates according to gender in rural and urban regions as well as the ratios of rural- to urban-suicide rates. Population density levels were used as a measure of urbanization. Differences in suicide rates across the rural-urban categories were investigated in terms of genders, age groups, suicide methods and family status using Spearman correlations.

RESULTS

The ratio of rural to urban suicide rates has continuously increased in both genders over the past 35 years, indicating a growing risk in rural areas. Suicide methods used in rural and urban areas vary significantly and suicide rates among men, but not women, were found to decrease with increasing urbanicity.

CONCLUSION

In line with recent findings from other western countries, we showed a growing gap between rural and urban suicide rates. This suggests a need for rural-specific suicide prevention efforts, especially aimed at the male rural population.

Genetics of suicide: a systematic review of twin studies

OBJECTIVES

Convergent evidence from a multitude of research designs (adoption, family, genomescan, geographical, immigrant, molecular genetic, surname, and twin studies of suicide) suggests genetic contributions to suicide risk. The present account provides a comprehensive and up-to-date review of the twin studies on this topic.

METHODS

A total of 32 studies (19 case reports, 5 twin register-based studies, 4 population-based epidemiological studies, 4 studies of surviving co-twins) located through extensive literature search strategies are summarized and discussed here. This literature corpus was published between 1812 and 2006 in six languages and reports data from 13 countries.

RESULTS

A meta-analysis of all register-based studies and all case reports aggregated shows that concordance for completed suicide is significantly more frequent among monozygotic than dizygotic twin pairs. The results of co-twin studies rule out exclusively psychosocially based explanations of this pattern. Population-based epidemiological studies demonstrate a significant contribution of additive genetic factors (heritability estimates: 30-55%) to the broader phenotype of suicidal behavior (suicide thoughts, plans and attempts) that largely overlaps for different types of suicidal behavior and is largely independent of the inheritance of psychiatric disorders. Nonshared environmental effects (i.e. personal experiences) also contribute substantially to the risk of suicidal behavior, whereas effects of shared (family) environment do not.

CONCLUSIONS

The totality of evidence from twin studies of suicide strongly suggests genetic contributions to liability for suicidal behavior. To further research progress in this area, an extensive discussion of design limitations, shortcomings of the literature and further points is provided, including sources of bias, gaps in the literature, errors in previous reviews, age and sex effects and twin-singleton differences in suicide risk, and notes from a history-of-science view.

Surname study of suicide in Austria: differences in regional suicide rates correspond to the genetic structure of the population

OBJECTIVES

There is convergent evidence from adoption, family, geographical, immigrant, molecular genetic, twin and, most recently, surname studies of suicide for genetic contributions to suicide risk. Surnames carry information about genetic relatedness or distance and, in patrilineal surname systems, are a close substitute for Y-chromosome markers and haplotypes, since surname transmission is similar to the transmission of the nonrecombining part of the Y chromosome. This study investigated whether differences in regional suicide rates correspond to the genetic structure of the Austrian population.

METHODS

Differences in district-level standardized suicide rates 1988-94 between the five major surname regions identified for Austria were analyzed. The surname regions used in the analysis reflect the contemporary population structure and closely follow the natural borders found in the topography of Austria, less so its administrative division into nine states.

RESULTS

Surname region accounted for a significant (P < 0.001) and substantial (38%) portion of the variance in district-level suicide rates. Adjusting the suicide rates for a set of five social and economic indicators that are established ecological correlates of suicide prevalence (income, and rates of the divorced, unemployed, elderly and Roman Catholics) left the results essentially unchanged.

CONCLUSIONS

Regional differences in suicide rates within Austria correspond to the genetic structure of the population. The present evidence adds to related findings from geographical and surname studies of suicide that suggest a role for genetic risk factors for suicidal behavior. Genetic differences between subpopulations may partially account for the geography of suicide. Study limitations and directions for future research are discussed.

Firearm legislation reform in the European Union: impact on firearm availability, firearm suicide and homicide rates in Austria

BACKGROUND

The availability of firearms in homes and at aggregate levels is a risk factor for suicide and homicide. One method of reducing access to suicidal means is the restriction of firearm availability through more stringent legislation.

AIMS

To evaluate the impact of firearm legislation reform on firearm suicides and homicides as well as on the availability of firearms in Austria.

METHOD

Official statistics on suicides, firearm homicides and firearm licences issued from 1985 to 2005 were examined. To assess the effect of the new firearm law, enacted in 1997, linear regression and Poisson regressions were performed using data from before and after the law reform.

RESULTS

The rate of firearm suicides among some age groups, percentage of firearm suicides, as well as the rate of firearm homicides and the rate of firearm licences, significantly decreased after a more stringent firearm law had been implemented.

CONCLUSIONS

Our findings provide evidence that the introduction of restrictive firearmlegislation effectively reduced the rates of firearm suicide and homicide. The decline in firearm-related deaths seems to have been mediated by the legal restriction of firearm availability. Restrictive firearm legislation should be an integral part of national suicide prevention programmes in countries with high firearm suicide rates.
