Parricide

Following a review of the literature on parricide, family violence theory is briefly explored regarding its applicability to understanding the parricidal family. Characteristics of the adult perpetrator, including the role of the victim, is discussed and two cases illustrating successful prevention are presented. Finally, two case illustrations are presented and the issue of preventive intervention based on the psychoeducation model is discussed.     

Twenty years of homicide and robbery in Chicago: The impact of the city's changing racial and age composition

Uniform Crime Reports (UCR) arrest and offense data for Chicago for 1960 to 1980 and population data from the 1960, 1970, and 1980 censuses are used to assess the extent to which demographic changes help explain trends in the city's homicide and robbery arrests. The results indicate that a changing racial composition contributed to changes in the age composition of Chicago's population as well as to changes in the homicide rate. Age-specific analysis by race and gender suggests that as much as 24% of the total increase in homicide arrests and 45% of the increase in robbery arrests (from 1962 to 1980) can be attributed to an increase in the number of nonwhite men in the population. Increasedrates of arrest of nonwhite men appear to account for large parts of the increases in homicide and robbery arrests, with increased rates for white men and nonwhite women also accounting for some of these increases. The paper closes with a discussion of the issues raised by these trends for Chicago and other urban areas.Revision of a paper presented at the 1984 Annual Meeting of the American Society of Criminology, Cincinnati.     

Temporal regularities in homicide: Cycles,seasons, and autoregression

It has long been assumed that there exists a relationship between crime (including homicide) and season. After discussing three analytic approaches to this problem (looking for seasonality, a general autoregressive process, and cycles), we review the literature and show that confusing and conflicting findings have been reported about the temporal regularities of homicide. Employing monthly data from the Supplementary Homicide Reports (1976–1989), we find evidence for seasonality, autoregression, and cyclicality of homicide. Our modeling approaches clarify the previous conflicting research; implications for theory and future research are discussed.The data utilized in this study were made available by the Inter-University Consortium for Political and Social Research. The data originally were collected by the Federal Bureau of Investigation. Neither the collector of the original data nor the Consortium bears any responsibility for the analyses or interpretations presented here. The authors contributed equally to this article.     

Aggregation,ratio variables,and measurement problems in criminological research

Issues of measurement error, level of aggregation, and ratio variables have been considered serious problems in criminological research. Although there have been many recent discussions of these issues in sociology and criminology, studies designed to assess the impact of these problems on the results of empirical research have, for the most part, been absent. After reviewing what is known theoretically and conceptually about these issues, an investigation which compares empirical analyses of a particular type of crime, homicide, that use different measurement strategies, different levels of aggregation, and ratio versus nonratio variables is presented. Utilizing homicide data from the mid-1970s and selected independent variables, the results of this investigation indicate that these three problems can interact in an empirical setting such that potential solutions to these problems do not always apply in the manner suggested in previous studies. The results also indicate that there is great risk in ignoring one or more of these problems in empirical research, in that different substantive conclusions can be reached from analyses that ignore these issues compared with analyses that deal directly with them.     

关于命案概念的思考——兼评“命案必破”之承诺

命案是一个历史范畴,从不同角度可以进行多种分类。人们对当前公安机关使用的命案概念分歧较大。从公安机关关注命案的目的着手,针对命案具有严重的社会危害性的特点,命案即经刑事诉讼定性的、行为人故意实施犯罪致死人命的案件。当前社会治安形势下,公安机关积极关注命案意义重大,但命案的侦破必然有其现实的底线,“命案必破”在理论上固然有其必然性,但在实践中只具有偶然性和可能性。     

质疑“命案必破“

以"命案必破"为目标固然在一定程度上有助于提高破案率,但却在根本上违背了马克思主义认识论的基本原理,违背了客观实际,曲解了实事求是原则的本来含义.如果用以指导侦查实践,极有可能导致有罪推定,侵犯犯罪嫌疑人的程序性权利和人身权利,甚至造成冤假错案.     

Urban homicide: Still the same

We use 1984–1986 data to estimate lifetime risks of being murdered in each of 50 large American cities and then compare these projections to others made earlier from 1971–1972 and 1976–1977 data. We find strong constancy over time in the average urban resident's murder risk (essentially a 1 in 68 chance of eventually being slain). Moreover, we find a high stability in the dispersion of risk by region, race, and city size and in the relative rankings of the 50 cities by murder risk. We comment briefly about such recent phenomena as the proliferation of crack and the resumption of capital punishment.Throughout this paper, we use the words murder, homicide, killing, and slaying interchangeably, meaning in all cases murder and nonnegligent manslaughter as defined by the FBI.     

Domestic Homicide: Neuropsychological Profiles of Murderers Who Kill Family Members and Intimate Partners

Domestic homicide is the most extreme form of domestic violence and one of the most common types of homicide. The objective was to examine differences between spontaneous domestic homicide and nondomestic homicide offenders regarding demographics, psychiatric history, crime characteristics, and neuropsychological status, utilizing neuropsychological test data from forensic examinations of 153 murderers. Using standard crime classification criteria, 33% committed spontaneous domestic homicides (SDH) and 61% committed nondomestic homicides (NDH). SDH offenders were more likely to manifest psychotic disorders, but less likely to be diagnosed with antisocial personality disorder or to have prior felony convictions. SDH offenders manifested significantly worse neuropsychological impairments than NDH offenders. The mean number of victims was lower for the SDH than the NDH group and only 14% of SDH offenders used a firearm, whereas 59% of NDH offenders used a firearm. These findings corroborate the notion that spontaneous domestic homicide may represent a discernible criminological phenotype.     

Beyond sticks and stones: Human capital enhancement efforts in response to violent crime in Latin America

Violent crime has been commonplace in Latin America over the past decades. While existing research has made progress in explaining the rationale and outcomes of government coercive strategies against crime, it has overlooked the non‐coercive strategies implemented to improve public security. It is argued in this article that political authorities make human capital enhancement efforts to shape actors’ incentives about criminal activity and mitigate crime. Accordingly, it is hypothesised that violent crime increases human capital enhancement efforts, and that the effect of violent crime on human capital enhancement efforts is larger when left‐oriented governments are in power because they stress actors’ motivations over windows of opportunities as the main drivers of crime. Support for these hypotheses is found in a sample of Latin American democracies in the period 1990–2007.     

Homicidal electrocution disguised as an accidental death

Deaths due to electrocution are mostly accidental. Homicide by electrocution is rarely reported in the literature. However, the location and pattern of the electrocution wound can raise concern for a possible homicidal manner of death. We are reporting an unusual case wherein the dead body of a middle-aged man was found lying in a suspicious condition on the roadside of desolated area. There were circumferential, grooved electrocution lesions over the left and right second toes with oval electrocution lesions on the medial aspects of both the left and right third toes. There were split lacerations over the right high parietal region, right pinna, and forehead. There was avulsion of the nail of the left thumb. Pressure abrasion was consistent with a ligature mark on the lower part of the left leg. The locations and pattern of these injuries raised the possibility of torture infliction. Death was attributed to electrocution, which was confirmed by histopathology. Autopsy findings and possible inferences were furnished to the police. This case highlights the careful observation of different characterizations and locations of the wounds and deducing inferences about the possible manner of death. This information can be useful to investigating agencies.
