Homicide-suicide and other violent deaths: an international comparison

Homicides followed by the suicide of the perpetrator constitute a serious form of interpersonal violence. Until now no study has directly compared homicide-suicides to other violent deaths from multiple countries, allowing for a better understanding of the nature of these violent acts. Using country-specific data, this study describes and compares the incidence and patterns of homicide-suicide as well as the relationship between homicide-suicide, homicide, suicide and domestic homicide in the Netherlands, Switzerland and the United States. The results indicate that cross-nationally, homicide-suicides are more likely than other types of lethal violence to involve a female victim, multiple victims, take place in a residential setting and to be committed by a firearm. Although homicide-suicides display many similarities across the different countries, differences exist regarding age and the use of firearms in the offence. This study indicates that homicides followed by suicides differ from both homicides and suicides in similar ways internationally. Cross-national differences in the availability of firearms may explain the international variation of homicide-suicide rates and patterns.     

Can Situational and Structural Factors Differentiate Between Intimate Partner and “Other” Homicide?

A large body of research has identified strong and consistent correlates of aggregated intimate homicide incidents; however, the bulk of these studies focuses on the influence of either case or neighborhood characteristics on homicide types, but not both. This study examines data collected from 739 homicides in two distinct metropolitan cities to determine which factors differentiate intimate and non-intimate homicide. Findings reveal that intimate partner homicides (IPH) are more likely to involve females both as victims and offenders when compared to non-IPH incidents. In addition, IPH homicides are more likely to be committed with weapons than non-IPH, but this finding only appears in Indianapolis homicides. Indeed, one of the stark contrasts between Indianapolis and Newark was the much greater prevalence of firearms involved in IPH homicides in Indianapolis. This suggests the need for future research that sorts out patterns of household gun possession, factors influencing community levels of household gun possession, and the use of legally- or illegally-possessed firearms in IPH homicide.     

Homicide–Suicide in Cuyahoga County,Ohio, 1991–2016

Research on homicides followed by suicides has relied heavily on small samples and relatively short time spans of data. This study helps to fill this gap by examining 26 years of homicide–suicide data from Cuyahoga County, Ohio, between 1991 and 2016. The main data source for the study is medical examiner files. Analyses of the data indicate the rate of homicide–suicide in Cuyahoga County is consistent with other studies but fluctuates considerably across years studied. The majority of victims are female while perpetrators are overwhelmingly male. Black people are overrepresented as victims and offenders. Use of drugs and/or alcohol leading up to the incident is common among perpetrators. Both the homicides and suicides were overwhelming committed with firearms. When comparing our results to the typology of murder–suicides developed by Marzuk, Tardiff, and Hirsch (JAMA 1992;267:3179), we find amorous jealousy is a significant motivating factor in a many cases, including those involving nonintimate partners. Our findings underscore the importance of widespread use of lethality assessment instruments.     

HOMICIDE TRENDS IN ATLANTA

In recent years in Atlanta, homicide has been the most common cause of death in males 20–40 years of age. To study homicide trends in this city we analyzed data for 591 resident victims of criminal homicide in two time perid. 1961–1962 and 1971–1972. Large increases occurred in the homicide rates for both black and white residents. In both races, these rate increases could be accounted for almost entirely by homicides involving firearms Homicide rates for black and whites in 1971–1972 were highest in census tracts with low indices of socioeconomic status; this association was found only for homicides in which the victim and assailant were relatives or acquaintances. There was little geographic overlap between areas with high rates of homicide in the home and high numbers of homicides in public. Using population-based rates facilitates comparisons of homicide occurrence between time periods and/or places.     

Aggression homicide and rejection homicide: a communicative classification of homicide

Based on a 10-year sample of homicides (n = 50), the hypothesis was tested that it is possible to differentiate between aggression and rejection homicide. The aggression homicide results from the offender/victim relationship, which is no longer accepted for some reason. In contrast, in the rejection homicide the offender radically strives for a goal which can only be reached if the victim is eliminated. Based on forensic-psychiatric expert opinions (n = 50), the case analyses yielded 31 aggression homicides and 18 rejection homicides, one case could not be classified. Aggression homicides differed significantly from the rejection homicides with regard to their main motives. Hate in quarrel (n = 8), violent occupation of the victim (n = 7), delusions (n = 5), revenge (n = 3), self-defence (n = 2), and jealousy (n = 1) characterized the aggression homicides, whereas rejection homicides were dominated by economic motives (n = 14). Two offenders intended to get rid of the victim and one offender wanted to rescue a third person. From a forensic-psychiatric point of view, the pertinent statistical data (social data, diagnosis, criminal responsibility) are reported and the significance of the differentiation between aggression homicide and rejection homicide for medico-legal or criminological case profiling and for the prognosis of the risk potential is discussed.     

State background checks and firearms homicides

This study examined the relationship between state firearms homicides and background checks for firearms purchases. Controlling for economic and social conditions, the estimated number of firearms in circulation, offenders under community supervision, and violent crime it was found that states with less stringent background checks on firearms purchases were significantly associated with firearms homicides. The large number of firearms circulating within the United States makes it likely that a motivated—but ineligible—person could obtain a firearm over the long-term in the secondary firearms market. Effective state background checks, however, may temporarily frustrate an unauthorized person from obtaining a firearm that, in turn, may contribute to lower firearms homicide rates. Implications for further research are examined.     

Prostitute homicides: a descriptive study

It has been estimated that women involved in street prostitution are 60 to 100 times more likely to be murdered than are nonprostitute females. In addition, homicides of prostitutes are notoriously difficult to investigate and, as such, many cases remain unsolved. Despite this large risk factor, little literature exists on homicides of prostitutes, and there is a lack of basic statistics and knowledge regarding this very specific victim group that could possibly help investigators. The aim of the current study is to conduct an exploratory study to explore the key characteristics of this group and how they differ from other subgroups of homicide. Forty-six cases of U.K. prostitute homicides are analyzed and compared to 59 male offender-female victim nonsexual homicide cases and 17 male offender-female victim sexual homicide cases.     

Covering Victims in the News: What Makes Minority Homicides Newsworthy?

The current study builds on the homicide and media criminological literature by examining the newsworthiness of 866 homicide incidents that occurred in Newark, NJ between 1997 and 2007. Recognizing that indicators of newsworthiness may vary by homicide victim gender and race/ethnicity, this study comparatively assesses the effects of suspect, victim, and incident variables on homicides against female, black, and Hispanic victims. A news media distortion analysis is employed which matches specific homicides to their respective local print news coverage. Overall, offense seriousness and victim vulnerability increase the odds of homicides receiving news media attention and being displayed prominently. We also find that different homicide characteristics serve as indicators of newsworthiness depending on victim gender and race/ethnicity. We discuss how cultural stereotypes may shape evaluations of newsworthiness and conclude with implications for theory and future research directions.     

Differences in female and male involvement in lethal violence in Russia

Relatively little is known of the distributions of homicide event characteristics in non-Western nations in which women relative to men are involved. This article utilizes unique homicide narratives drawn from Russian court and police records to compare homicide victim, offender, and event characteristics by sex of victim and separately by sex of offender. Results from logistic regression show that homicides in which a female was the victim or offender were more likely to occur between intimates and to occur in the home, whereas homicides involving males were more likely to occur in a public place, to be alcohol-related, to involve a firearm, and to involve a victim and offender who did not know each other well. These results not only present an important first glimpse at women as homicide victims and offenders in Russia specifically, but also provide a point of comparison with findings from similar analyses undertaken in the West, and present further initial observations upon which to construct a cohesive theory about female involvement in serious violent events.     

A 28-year (1963-90) study of homicide in Marion County, Oregon.

We describe 240 consecutive homicidal deaths that occurred in Marion County, Oregon, over a 28-year period (1963-90). An epidemiological assessment of the homicides yielded the following information: More than 91% of these deaths were primary homicides. In primary homicide, 63% of the victims and 88% of the offenders were male. In secondary homicide, 76% of the victims and all of the offenders were male. A high percentage of victims (83%) and offenders (84%) in primary homicide were Caucasian, as were 100% of victims and offenders in secondary homicide. About 12% of victims and 10% of offenders in primary homicide were Hispanic. Fifty-nine percent of primary homicides were intrasexual, as compared to 87% of secondary homicides. An intraracial pattern was found in 90% of primary homicides and in 100% of secondary homicides. The most frequent means of death in both primary and secondary homicides were firearms, physical beating, and stabbing. Strangers committed 80% of secondary homicides. This was in marked contrast to the victim-offender relationship found in primary homicides, where strangers were responsible for approximately 16% of the total, acquaintances for approximately 36%, and family members for approximately 48%. The overall clearance rate (i.e., the identification and charging of a suspect for the death) was 88%.     

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.     

Fatal head injuries from firearms. An autopsy study of 270 cases

Autopsy findings in 270 fatal head injuries from firearms are reported, including 243 suicides and 27 homicides. The most frequent weapon used for both groups were shot guns which are easily available in Norway. For suicides the most favored sites were right tempoparietal, frontal, and mouth. Twenty-six percent of the victims from homicides had multiple wounds in their head. Suicide by firearms showed marked male predominance, whereas the sex ratio for homicide was rather equal between the two sexes.     

A case of suicidal hanging staged as homicide

Suicides staged as homicides are rarely encountered by crime scene investigators. The case of one such staged homicide is presented in which the victim used restraints during a hanging. No other cases of suicidal hangings staged as homicides could be found in the forensic literature. Similar cases should be reported so additional data can be gained from these deaths to help reveal indicators of suicide rather than homicide.     

Comparing Homicide‐Suicides in the United States and Sweden

Research on homicides followed by suicides has largely relied on very localized samples and relatively short time spans of data. As a result, little is known about the extent to which patterns within cases of homicide‐suicides are geographically specific. The current study seeks to help fill this gap by comparing twenty years of homicide‐suicide data for Sweden and a large U.S. county. Although some of the underlying patterns in the two countries are similar (e.g., decreasing rates), a number of important differences emerge, particularly with respect to incidence, weapons used, perpetrator age, and relationship of the perpetrator to the victim.     

Accomplishing Difference: How Do Anti-race/Ethnicity Bias Homicides Compare to Average Homicides in the United States?

Research on the nature of bias homicide has experienced increased interest in the academic literature. To date, few studies have compared the similarities and differences between anti-race/ethnicity bias homicides and average American homicides. Consequently, we know little about how the offender, victim, and situational characteristics compare across these two homicide types. Drawing from doing difference theory of bias crime, the aim of this study is to comparatively analyze the attributes of anti-race/ethnicity homicides to average homicides between 1990 and 2014. Anti-race/ethnicity homicide data is extracted from the U.S. Extremist Crime Database and paired with average homicides from the Federal Bureau of Investigation’s 2000 Supplementary Homicide Reports. The results of this study suggest that the characteristics of anti-race/ethnicity homicides are both similar and different from average homicides. Implications for bias crime theory, research, and policy are discussed.     

Differentiating sexual violence: A comparison of sexual homicide and rape

Abstract

The present study sought to identify consistent patterns in the actions of sexually violent offenders to determine whether sexual homicide and rape reflect different behavioral emphasis of a single thematic model of sexual assault. Crime scene behaviors of 74 (37 sexual homicides and 37 rapes) solved cases of sexual assaults were compared, and results of a multi-dimensional analysis revealed three thematic styles of interacting with the victim during a sexual assault (Exploit, Control, and Violent). Further analysis indicated that offender–victim interactions in sexual homicide and rape are predominantly distinguished by the degree of violence, such that behaviors associated with each type of offense were found to occur in two discrete areas along a single continuum. Findings are discussed in terms of producing a general framework for understanding sexual violent interactions.     

CIRCUMSTANCES IN SUPPLEMENTARY HOMICIDE REPORTS: VARIETY AND VALIDITY*

This paper presents a critical examination of homicide circumstances as reported in supplementary homicide reports (SHR). Different types of homicides can be distinguished by the circumstance codes and victim/offender relationship recorded on the SHR. Delineating murder by type invites analysis of this offense from a victimization perspective–homicides have much in common with nonlethal offenses. Different types of homicide present different policy problems to police. The paper also discusses various sources of error in SHR data, which must be recognized by researchers interested in theoretical or policy questions.     

Cocaine and homicide in Memphis and Shelby county: an epidemic of violence

In Memphis and the surrounding county, there were a record number of homicides (179) in 1986. During the same year, there was a marked increase in medical examiner cases where tests were positive for cocaine or its metabolites. Review of medical examiner and toxicology records from 1980 to 1986 found 87 cocaine related deaths; 46 of these were homicides. In 1986 alone, there were 53 cocaine related deaths, all manners, and 31 cocaine related homicides. In this year, 17.3% of the homicides were positive for cocaine or metabolite. The cocaine related homicides were similar to other homicides in terms of age, race, sex, blood ethanol concentration, and cause of death being due most often to firearms. In homicide cases in which an abuse drug was detected, cocaine accounted for the entire increase in 1986. Police records indicated that cocaine directly contributed to the homicide in 39% of the cases in which the drug was found. In other cases, we speculate that cocaine altered behavior may have contributed to the victim's being murdered either during the drug "high" or during the posteuphoric depression or withdrawal phase.     

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.
