Homicide by a Forensic Female Sample in Brazil: A Preliminary Study

The objective of the study was to evaluate the mental status of all women (n = 14) who were acquitted by reason of insanity of charges of murder or attempted murder and committed to a forensic psychiatric hospital in the state of Rio de Janeiro, Brazil. All cases were retrospectively examined, including medical files, technical records, and forensic experts' official reports. A conclusive psychiatric diagnosis was established using the Structured Clinical Interview for DSM‐IV Axis I and II Disorders and clinical and forensic records. The most common diagnosis was schizophrenia/schizoaffective disorders (n = 8; 57.3%). Most victims (n = 12; 75%) were close relatives of the patients. We found that 43% (n = 6) of the patients had a previous history of violent behavior. According to the initial psychiatric forensic evaluation, 5 patients (35.7%) had psychotic symptoms. It is expected that a growing understanding of motivational factors underlying homicidal behavior in mentally disturbed female offenders may further the implementation of effective preventive and therapeutic interventions.     

Autopsy Reenactment – A Useful Technique in the Evaluation of Adhesive Tape Asphyxia

A 19‐year‐old woman was found dead with her face and head wrapped in plastic adhesive tape in a cupboard beside an opened helium cylinder. Despite the alleged presence of a suicide message on a social networking website, the unusual circumstances raised the possibility at the time of autopsy of either accidental death from sexual asphyxia or homicide. A carefully monitored reenactment demonstrated, however, that the type of commercial adhesive tape that had been used did not cause complete airway obstruction and that it was possible to wrap a considerable length of tape around the head and neck with the breath held. All of the features at autopsy were, therefore, compatible with self‐infliction. Asphyxial death was attributed to the combined effects of smothering from tape and anoxia from helium, an extremely rare combination in young females.     

故意杀人案件的主要特点及其讯问要领

故意杀人案件是一种严重危及人身安全的暴力性犯罪案件。该类案件呈现出案前多有预谋、现场留有丰富证据、因果关系较为明显、犯罪嫌疑人讯问中畏罪心理比较突出等特点。对故意杀人案件嫌疑人的讯问要遵循熟悉研究案情、采取恰当的突破方式、采取适当的讯问策略以及深挖犯罪的基本思路。同时,还应从犯罪事实和犯罪证据方面把握对故意杀人案件嫌疑人的讯问。     

Unemployment and Crime: Toward Resolving the Paradox

While official crime statistics from many countries show that unemployed people have high crime rates and that communities with a lot of unemployment experience a lot of crime, this cross-sectional relationship is very often not found in time-series studies of unemployment and crime. In Australia there have been no individual-level or cross-sectional studies of unemployment and adult crime which have failed to find a positive relationship and no time-series which have supported a positive relationship. Consistent with this pattern, a time series of homicide from 1921 to 1987 in Australia reveals no significant unemployment effect. A theoretical resolution of this apparent paradox is advanced in terms of the effect of female employment on crime in a partriarchal society. Crime is posited as a function of both total unemployment and female employment. When female employment is added to the model, it has a strong positive effect on homicide, and unemployment also assumes a strong positive effect.     

INTEGRATING RACE,PLACE AND MOTIVE IN SOCIAL DISORGANIZATION THEORY: LESSONS FROM A COMPARISON OF BLACK AND LATINO HOMICIDE TYPES IN TWO IMMIGRANT DESTINATION CITIES*

In this paper, we examine and compare the impact of social disorganization, including recent immigration, and other predictors on community counts of black and Latino motive‐specific homicides in Miami and San Diego. Homicides for 1985 to 1995 are disaggregated into escalation, intimate, robbery and drug‐related motives. Negative binomial regression models with corrections for spatial autocorrelation demonstrate that there are similarities and differences in effects of social disorganization and other predictors by motive‐specific outcomes, as well as for outcomes across ethnic groups within cities and within ethnic groups across cities. Recent immigration is negatively or not associated with most outcomes. Overall, the study shows the importance of disaggregating homicide data by race/ethnicity and motive and demonstrates that predictions based on existing theories are qualified on local conditions.     

The Application of Missing Data Estimation Models to the Problem of Unknown Victim/Offender Relationships in Homicide Cases

Homicide cases suffer from substantial levels of missing data, a problem largely ignored by criminological researchers. The present research seeks to address this problem by imputing values for unknown victim/offender relationships using the EM algorithm. The analysis is carried out first using homicide data from the Los Angeles Police Department (1994-1998), and then compared with imputations using homicide data for Chicago (1991-1995), using a variety of predictor variables to assess the extent to which they influence the assignment of cases to the various relationship categories. The findings indicate that, contrary to popular belief, many of the unknown cases likely involve intimate partners, other family, and friends/acquaintances. However, they disproportionately involve strangers. Yet even after imputations, stranger homicides do not increase more than approximately 5%. The paper addresses the issue of whether data on victim/offender relationships can be considered missing at random (MAR), and the im-plications of the current findings for both existing and future research on homicide.     

The effects of marital status on adult female homicides in the United States

With data from the 1992 Mortality Detail File, we examine the effects of marital status on female homicide victimization in the United States. Multivariate logistic regression was fitted to all female homicide deaths occuring in 1992. Results indicate that, controlling for race, education, nativity, city size, region of the country, occupation, age, day of the week, and month of the year, divorced females were 55.3% more likely to be homicide victims than married females. Notably, single women did not differ from married women with respect to homicide risk. Finally, widowed women were significantly less likely to be homicide victims than married women. The results suggest a complicated relationship between marital status and female homicide victimization.     

Sociostructural Considerations of Domestic Femicide

Previous research on the domestic murder of women is relatively scant. Domestic femicide data collected from 32 state domestic violence coalitions was regressed on variables associated with three theoretical explanations: economic stress and inequality variables, criminal justice variables, and community variables. Findings suggest that state size has the largest impact on the number of domestic femicides, perhaps because of the relationship between state size and other variables such as poverty and public services. Not related to domestic femicide are variables such as the number of officers on the street, the number of violent crimes, or household income.     

论命案防破环境的和谐构建

公民的生命健康权是我国人权保障最重要的部分之一,公安部从改革发展稳定的大局和加强党的执政能力建设的高度出发,提出了"命案必破"。命案防范与命案侦破紧密联系,二者相互促进、相互统一,相互依赖,相辅相成,必须两者相结合,才能更好的保障公民的生命健康权。     

Determined to Die! Ability to Act Following Multiple Self‐inflicted Gunshot Wounds to the Head. The Cook County Office of Medical Examiner Experience (2005–2012) and Review of Literature

Cases of multiple (considered 2+) self‐inflicted gunshot wounds are a rarity and require careful examination of the scene of occurrence; thorough consideration of the decedent's psychiatric, medical, and social histories; and accurate postmortem documentation of the gunshot wounds. We present a series of four cases of multiple self‐inflicted gunshot wounds to the head from the Cook County Medical Examiner's Office between 2005 and 2012 including the first case report of suicide involving eight gunshot wounds to the head. In addition, a review of the literature concerning multiple self‐inflicted gunshot wounds to the head is performed. The majority of reported cases document two gunshot entrance wound defects. Temporal regions are the most common affected regions (especially the right and left temples). Determining the capability to act following a gunshot wound to the head is necessary in crime scene reconstruction and in differentiation between homicide and suicide.
