故意杀人罪量刑情节与宣告刑量关系实证研究——基于SPSS软件包所作的“相关”分析

作为联结故意杀人罪罪量与宣告刑量纽带的量刑情节与宣告刑量之间存在着紧密联系。在目前的司法实践中,各种量刑情节对宣告刑量的影响程度迥然不同,如是否共同犯罪与宣告刑量的相关系数高达0.481,危害结果变量与宣告刑量的相关系数高达0.412,被告人过错变量与宣告刑量的相关系数达到-0.279;而是否累犯变量与宣告刑量的相关系数仅为-0.145,是否残忍变量与宣告刑量的相关系数公为-0089.     

论系列杀人案件的信息披露工作

侦查工作的成败,很大程度上取决于案件信息占有量和信息利用程度。系列杀人案件的社会危害性大,侦查难度大,必须正确地串并案件,充分利用已掌握的信息,结合对犯罪嫌疑人进行的犯罪心理画像,通过适当的案件信息披露方式来发动群众协助破案,并警示群众自我防护。     

Sharp Force Homicide in Denmark 1992–2016

Sharp force trauma is a common homicide method. The weapon is typically a knife, which is easily accessible and does not require special skills. We have analyzed all 471 sharp force homicides in Denmark during 1992–2016 with special focus on aspects that are relevant to forensic pathologists, including the distribution of wounds and organ injuries. Most homicides were committed inside with a kitchen knife. The front left thorax was the most common area to be affected by sharp force trauma. In 18.9% of the victims, there was only one sharp injury, the majority on the thorax. The most common trajectory for stab wounds was directly posterior with no deviation to the sides or up/down followed by directly anterior. The heart (including pericardium) and lungs (including hemo- and pneumothorax) had injuries in more than 75% of the victims. 67% of victims were males. Female victims had more sharp force injuries and defense wounds than male victims. Most females were killed in domestic homicides (73.7%), most commonly in partner killings (56.4%). In contrast, many male victims were killed in a setting of nightlife/intoxication (34.0%) most by a friend/acquaintance delivering a few stab wounds. The results clearly show strong sex differences in both victims and offenders. This could be useful for shaping policies and public opinion, and as a route for understanding the developments in interpersonal violence. In the narrow setting of death investigation, our results will provide an evidence-based approach to understanding the injury patterns in sharp force homicide.     

Murder in Mexico: are journalists victims of general violence or targeted political violence?

Journalists in Mexico face hundreds of attacks each year, ranging from online harassment and physical intimidation to outright murder. The official narrative typically claims that murdered journalists are the victims of general criminal violence. This article finds that despite the rampant violence in Mexico, the murder of journalists cannot be attributed to the country’s general criminal violence problem alone. Instead, the evidence points to the targeting, and even political targeting of journalists. First, journalists are at a much higher risk of being murdered than the general population. Second, the divergence between homicide rates among the general population and among journalists varies considerably between Mexican states. While recent scholarship has shown that subnational governments can successfully remain authoritarian despite democratization at the central or federal level, this literature has largely ignored the use of political killings in subnational undemocratic regimes. This article attempts to understand the murder of journalists not just as a problem of criminal violence, but also of political violence, and thereby connects the findings to the existing scholarship on subnational authoritarianism.     

Asphyxia Homicides in Finland, 1983–2012

Finland has one of the highest homicide rates in Western Europe, and almost every tenth homicide is caused by asphyxiation. Reliable statistics, a strict legislation, and an exceptionally high medico-legal autopsy rate formed a base for a nationwide analysis of asphyxia homicides (n = 383) during 30 years. The cases were identified through multiple records, and all the forensic pathology case files were studied in detail. In more than one out of five cases, there were indications of staging, and the homicide was revealed first at autopsy in close to one in ten cases. The vast majority of the homicides took place in private locations and involved persons known to each other. Every third victim was an intimate partner, and every tenth a child. Almost half of the victims died from manual strangulation, one in three from ligature strangulation. Smothering, choking, neck compression with a firm object, and thoracic compression were more rare methods. Drownings were excluded from this study material. Of all the victims, 7% had no observable external injuries. Petechiae were recorded in approximately in 61%, laryngohyoid fractures in 47%, and vocal cord hemorrhages in 16% of the cases. Every tenth female victim had genital injuries. Toxicological analyses were performed in close to all of the cases, and almost three out of four victims tested positive for blood alcohol. The various aspects of the demographics and autopsy findings covered in this study contribute reliable and accurate data to further strengthen the spectrum of observable medico-legal characteristics of asphyxia homicides.     

Homicide by unusual‐edged weapons: Forensic considerations of two cases

Homicide by stab wound is common worldwide. However, the use of unusual edged weapons is rarely reported in the forensic literature. Here, we report two cases of homicide involving a Japanese sword, or katana, and a sickle. Both of these weapons can create either stab or incised wounds with some particularities. In our cases, characteristics of the external wounds, internal injuries, and the depth of penetration raised the possibility of an unusual weapon. Meticulous forensic examination of these injuries (morphological characteristics, depth of penetration, trajectories, and cut marks in the bone) may allow the forensic expert to determine the type of weapon used.     

Identifying Unit-Dependency and Time-Specificity in Longitudinal Analysis: A Graphical Methodology

Longitudinal analysis in criminology and other social sciences has become an important research tool because it allows us to draw conclusions from observing how multiple units change over time. Unfortunately, its results are more vulnerable to potential influences of unusual observational units or periods of time. Current leverage diagnostics are designed for cross-sectional analysis and are fallible when applied to longitudinal models. This article introduces a graphical diagnostic methodology to systematically examine the sensitivity of longitudinal results to extreme observational units and periods of time—unit-dependency and time-specificity. Further the article illustrates its use with an example testing policy effects on black and white female victimization of intimate partner homicide. Results are displayed in an easily understood graph that provides a snapshot of the results' time-specific patterns and robustness to unit-dependency. Currently, comparable tests for panel analysis are tedious and cumbersome. With this new illuminating methodology, researchers and policy-makers can easily decide whether a time-specific or unit-dependent pattern is consequential.     

Crime patterns and their relation to subjective social stress and support indicators: The role of gender

This study investigated the relationship between the subjective perception of stress and support in the population (as independent variables) and the prevalence of homicide, robbery, and property offenses in society, while controlling for the effect of gender, i.e., how these crimes are related to the differential perception of stress and support among males and females. The theoretical framework is provided by a stress-support model which postulates that crime in society will be positively related to stress factors and negatively related to support systems. Eight stress indicators and four support (solidarity) indicators were included. The data regarding these indicators were derived from continuing surveys of representative samples of the urban population in Israel during the years 1967–1979. The theoretical model was supported by the findings, especially those relating to property offenses. The effects of the female indicators were strongest (and greater than those of males) with regard to property offenses. The regression coefficients of the female indicators were also consistently larger than those of males, indicating that women's perceptions of stress are better predictors of crime rates than those of males. The results are compared to those of previous studies and suggestions are made for future studies in this new line of criminological research.
