WHO KILLS WHOM IN SPOUSE KILLINGS? ON THE EXCEPTIONAL SEX RATIO OF SPOUSAL HOMICIDES IN THE UNITED STATES*

A hitherto unremarked peculiarity of homicide in the United States is that women kill their husbands almost as often as the reverse. For every 100 US. men who kill their wives, about 75 women kill their husbands; this spousal “sex ratio of killing” (SROK) is more than twice that in other Western nations. Our analyses of spousal homicide samples from the United States, Canada, Australia, and Great Britain indicate that this contrast cannot be attributed to greater gun use in the United States, nor to a domain-general convergence of the sexes in their uses of violence. Significant predictors of the spousal SROK include registered versus de facto marriage, coresidency versus separation, ethnicity, and age disparity, but the impacts of these variables are not sufficient to explain the differences between US. and other nations’victim sex ratios.     

Homicide–Suicide in China: an Exploratory Study of Characteristics and Types

This study explores 63 homicide–suicide cases that include two or more homicide victims, in the People’s Republic of China. This is the first study to examine homicide–suicide in the Chinese context, following calls to develop a research strategy outside of the USA and Europe. Data are derived from a content analysis of Chinese news sources from 2000 to 2014. Findings show homicide–suicide offenders are likely to be married males living in rural cities who kill their intimate partners and/or children inside a residence using knives. Intimate partner conflict and extramarital affairs are precipitating factors in almost half of the incidents. Patterns of homicide–suicide in China are comparable to those in high-income countries, except that firearms are not the primary means in China and there is no evidence of “mercy killing” among older persons, as described in western homicide–suicide studies. Findings are related to the social and economic structure of Chinese society. Clinical and policy implications include the need for greater transparency and a nationwide homicide and suicide tracking system in China, stricter domestic violence laws, postmortem studies of the brains of homicide–suicide offenders, and psychological autopsies on homicide–suicide perpetrators.     

Abused South Korean women: a comparison of those who do and those who do not resort to lethal violence

This study compares two groups of women in South Korea: one group incarcerated for the deaths of their male partners and the other staying in a shelter for battered women. The analysis serves to answer two questions: First, are the findings regarding women who kill their intimate partners in Western societies generally applicable to their counterparts in South Korea? Second, how are abused South Korean women who resort to lethal violence against their abusers different from those who do not? Regarding both abused and nonabused women incarcerated for criminal homicide against their partners, results indicate that they have less experience of psychological and physical abuse by their partners and that they are less educated, underemployed, and more supportive of traditional patriarchal norms than are the women who utilize domestic violence shelters. This research explores implications for intervention strategies to encourage abused women to seek help from legal and extralegal sources.     

Incarcerated Battered Women: A Comparison of Battered Women Who Killed Their Abusers and Those Incarcerated for Other Offenses

The present study compared battered women incarcerated for killing/seriously assaulting their abusers with battered women incarcerated for other offenses to explore possible similarities and differences in the characteristics and experiences of the two groups as well as to determine what factors may lead some battered women to use lethal force against their partners. Comparisons were made on a number of variables including sociodemographic factors, characteristics of the battering relationship, alcohol/drug use of battered women and their abusers, perceived social support, actions taken to end the violence, prior criminal behaviors, and childhood trauma factors. Findings revealed that women in the homicide/assault group were older, in the relationship longer and experienced a longer duration of violence in this relationship. They also experienced more frequent and severe battering, including sex assaults and sustained more injuries than those in the comparison group. Further, battered women who killed/seriously assaulted their partners were more likely to believe that their lives were in danger, were less likely to use violence against their partners, and were less likely to have a prior criminal record or to have served time previously. The implications of the findings are discussed.     

Hands-on Killing of Intimate Partners as a Function of Sex and Relationship Status/State

Guided by evolutionary psychology and a situational perspective on violence, we generated three hypotheses to investigate whether the percentage of intimate partner homicides by beating, a hands-on homicide method, varies with the victim-offender relationship. We tested these hypotheses with a national database that includes incident-level information on over 50,000 intimate partner homicides. Results indicate that: (1) men are more likely than women to kill a partner by beating, and (2) men are more likely to kill their partners by beating when the relationship is dating or non-marital cohabiting (versus legal marriage). We argue that the lack of commitment in these non-marital relationships may produce greater jealousy in men, driving the perpetrator to kill his victim in a more violent manner (i.e., beating), relative to men who kill their wives.     

Homicide Trends and Illicit Drug Markets: Exploring Differences Across Time

Ample speculation and some evidence suggests that the decline in homicide rates since the early 1990s was partially attributable to declining levels of drug market activity. This analysis explores that explanation, along with an alternative: the strength of the drug market–lethal violence relationship has weakened over time. We outline several conceptual reasons to expect period‐specific differences in the drug market–homicide relationship. These include the aging of market participants, shifts in the normative and transactional climate of markets, and changes in structural factors affecting the magnitude of the relationship between drug market indicators and homicide rates (such as socioeconomic disadvantage). These arguments are evaluated for a sample of large US cities. The results generally show a pattern of attenuation in the drug market–homicide relationship and lead us to conclude that part of the homicide decline is likely due to a drop in the amount of drug market activity, some of it is attributable to the aging of drug market participants, and some appears to be due to unmeasured factors which may have created a “kinder and gentler” drug market.     

DISENTANGLING THE EFFECTS OF GENDER AND INTIMACY ON VICTIM PRECIPITATION IN HOMICIDE*

Research indicates that incidents in which women kill their husbands are more likely to involve victim precipitation than incidents in which men kill their wives. Formulating a causal interpretation of this finding, however, is complicated because the observed pattern may reflect gender differences in violence rather than any special dynamics between husbands and wives. In this research, we introduce and illustrate a framework for disentangling the effects of intimacy and gender on violence. We examine the additive and multiplicative effects of the gender of the offender, the gender of the victim, and the relationship between the offender and victim on victim precipitation. For the most part, the pattern of victim precipitation in homicide reflects the fact that males tend to be more violent than females. However, we find some evidence of special dynamics for intimate partner homicides: Men who are killed by their partners tend to have more violent records than men who are killed in other circumstances.     

Helping women understand their risk in situations of intimate partner violence

Only approximately one-half of the 456 women who were killed or almost killed by a husband, boyfriend, or ex-husband or ex-boyfriend in a recent national study of homicide of women accurately perceived their risk of being killed by their abusive partner. Women are unlikely to overestimate their risk; however, many will underestimate the severity of the situation. From the same study, it was found that relatively few of the victims of actual or attempted intimate partner femicide were seen by domestic violence advocates during the year before they were killed; they were far more likely to be seen in the health care system. Implications are drawn as to innovative ways that women who are abused can be identified and with skilled assessment of the danger in their relationship helped make more informed plans for their safety.     

DOES VIOLENCE INVOLVING WOMEN AND INTIMATE PARTNERS HAVE A SPECIAL ETIOLOGY?*

We used data from a survey of inmates who have committed homicide or assault to examine whether men and women who have killed or assaulted their intimate partners are different from other violent offenders. A “gender perspective” implies that intimate partner violence and violence between the sexes have different etiologies than other types of violence, whereas a “violence perspective” implies that they have similar etiologies. Our evidence supports a violence perspective. In general, offenders who attack their partners are similar to other offenders in terms of their prior records, alcohol and drug use, and experiences of abuse. We observed some differences between men who attack women (including their female partners) and other male offenders, but the differences were opposite those predicted by a gender perspective. For example, men who attacked their partners were particularly likely to have been abused by their partners. In addition, men who attacked women were particularly likely to have experienced sexual abuse during childhood and to have been intoxicated at the time of the incident. These results suggest that some well-known predictors of violence are particularly strong predictors of male violence against women and female partners.     

Heterosexual intimate partner homicide: review of ten years of clinical experience

Most of the literature on intimate partner homicide addresses violence between the two partners, spousal abuse, and family violence. There is less focus on the relationship of mental illness, intellectual functioning, and drug and alcohol abuse to these homicides. We investigated this type of homicide in a collection of forensic cases seen by the first author over a period of 10 years. Twenty-eight patients who underwent forensic psychiatric evaluation for heterosexual intimate partner homicide from August 1993 to June 2003 were studied using a retrospective case review methodology. We found that firearms were used as the method of killing more often by females than by males. We also compared method of killing with substance abuse and intoxication at the time of the homicide. Educational status indicates that this group of accused perpetrators is functioning at higher intellectual levels compared with a previously studied sample of filicides. We also found significant presence of serious mental illness in our sample of accused perpetrators of heterosexual intimate partner homicide.     

Young women and gang violence: Gender,street offending,and violent victimization in gangs

Drawing on multiple data sources in St. Louis, this article examines how gendered situational dynamics shape gang violence, including participation in violent offending and experiences of violent victimization. Combining an analysis of in-depth interviews with young women in St. Louis gangs with an examination of homicide reports from the same city, we find that young women, even regular offenders, highlight the significance of gender in shaping and limiting their involvement in serious violence. They use gender both to accomplish their criminal activities and to temper their involvement in gang crime. Consequently their risk for serious physical victimization in gangs is considerably less than young men's. St. Louis homicide data collaborate these qualitative findings. Not only are young women much less likely to be the victims of gang homicide, but the vast majority of female gang homicide victims were not the intended targets of the attack. In contrast, homicide reports suggest that the majority of male gang homicide victims were the intended targets. We suggest that gendered group processes and stratification within gangs are key factors explaining both violent offending and victimization risk in gangs.     

Women who kill: a comparison of the psychosocial background of female and male perpetrators

The purpose of this study was to compare the psychosocial background of female and male perpetrators convicted of homicide in Sweden between 1995-2001. All women (n=43) who were convicted for lethal violence during the period and a corresponding number of randomly chosen men (n=43) were examined. In total, information about 86 individuals was collected retrospectively. Areas of interest were psychosocial variables during childhood and at the time of the current crime. Results showed that both female and male perpetrators were psychosocially encumbered already at an early age. Homicidal women had more severe childhood circumstances, but less aggressive childhood behaviour than did their male counterparts. At the time of the crime, women had a more ordered social situation, had more often been exposed to violence and searched for help than had the men. These gender differences suggest that specific actions are needed for preventing women's homicidal behaviour.     

Crime is Part of the Problem: Contexts of Lethal Violence in Finland and the USA

According to Zimring & Hawkins, the exceptionally high level of homicide in the USA is unrelated to the nation's overall crime problem. In contrast to this statement, a critical review of their evidence suggests that criminal activity may explain a significant share of the excess levels of lethal violence in the USA. As a first step towards testing this hypothesis, we have created a uniform victim-level data file of information on the method and the situational context of homicide cases in Finland and the USA. In support of the hypothesis, we find that homicides that occur in the context of another crime are much more prevalent in the USA than in Finland. This difference accounts for 35% of the overall gap in the homicide rate between these two nations. Moreover, our research indicates that the effect of the criminal context cannot be reduced to the 'instrument effect', i.e. the fact that handguns are much more prevalent in the USA. In light of these findings, it would be premature, in terms both of theory and of public policy, to treat lethal violence as a problem entirely independent of other crime.     

EXAMINING THE CONDITIONAL NATURE OF THE ILLICIT DRUG MARKET-HOMICIDE RELATIONSHIP: A PARTIAL TEST OF THE THEORY OF CONTINGENT CAUSATION

Recently, Zimring and Hawkins (1997) have suggested that drug markets are a “contingent cause” of the increase in homicide rates. That is, where structural conditions known to produce violence are already in place, the drug distribution‐homicide link may be exacerbated. This analysis uses hierarchical linear modeling to investigate two key research questions: (1) Is within‐city variation in illicit drug market activity positively associated with within‐city variation in homicide rates during the 1984–1997 period? (2) Is the illicit drug market‐homicide association contingent on preexisting violence conducive socioeconomic conditions? Using three measures of drug market activity, analyses provide affirmative evidence on both questions. Theoretical and research implications of these findings are discussed.     

Female juvenile murderers: Biological and psychological dynamics leading to homicide

The increasing involvement of girls under 18 in violent crime has been a matter of growing concern in the United States in recent years. This article reviews the arrests of female juveniles for violent crime and then focuses specifically on their involvement in homicide. Arrests of girls for murder, unlike arrests for assault, have not risen over the last 30 years, suggesting that the dynamics that propel female juveniles to engage in lethal violence differ from those contributing to assaultive behavior by this same group. A review of the literature indicates that theories as to why female adolescents kill do not take into account recent scientific findings on brain development and the biological effects of early trauma in explaining serious violent behavior by girls. Three cases, evaluated by the authors, involving female adolescents charged with murder or attempted murder, are presented. The authors focus on the biological and psychological dynamics that help explain their violent behavior. They discuss the effects of insecure attachment and child maltreatment, and trace a critical pathway between these early experiences and future risk of violent behavior. The dynamics of child maltreatment in fostering rage and violence are discussed thereafter in terms of offender accountability. The article concludes with a discussion of treatment and recommendations for future research.     

Fighting back: Lethal responses to predatory attacks

Each year millions of Americans become victims of predatory crimes. The way victims respond to these attacks varies from complicance with offenders' requests to physically challenging offenders. In some cases, the physical defense of self and property has lethal consequences for the initial offender. While much is known about felony murder victims and typical homicide offenders, little is known about individuals who fight back against predatory attack by using lethal violence. In this paper, we use data from the Homicides in Chicago, 1965–1995 study to describe the characteristics of defensive homicide offenders and to determine how they compare with felony murder victims and defensive homicide offenders. Our results indicate that defensive homicide offenders are more similar to typical homicide offenders than felony murder victims, and are even more likely to have violent criminal histories and to use firearms than typical homicide offenders. Our results challenge the common perception that individuals who fight back against predatory attack are simply “law-abiding citizens.” We conclude the paper with a discussion of the implications of our study for additional research and police practice.

Economic Development,Change of Age Distribution,and Stream Analogy of Homicide and Suicide: A Cross-National Assessment

The current study tests the stream analogy of lethal violence, proposed by Unnithan et al. on a large sample of 124 nations. Spatial econometric regression models confirm that economic development decreases homicide rate and increases suicide–homicide ratio (SHR). The SHR developed by Unnithan et al. accounts for the impact of economic development better than original measure of suicide rate. The most important finding of the current investigation is that the increase in the population size of the elderly, consequent to economic development, is partially responsible for elevated suicide rates and SHRs.
