An Assessment of the Quality of Homicide Data in the Supplementary Homicide Reports: A Research Note

The Federal Bureau of Investigation (FBI)’s Supplementary Homicide Reports (SHR) is a national-level incident-based data clearinghouse for homicide events in the USA used in countless research studies to track homicide trends, test theory, and analyze policy. Despite its wide use, the SHR has well-known limitations. This research note examines the accuracy of the information in the SHR by comparing homicide cases in Newark, New Jersey with their respective data to determine the level of disagreement between the data sources, which variables exhibit the greatest disagreement, and the case-related variables related to the disagreement. Uniquely, we do this for cases where offenders are known in the SHR. Our findings suggest that variables such as victim-offender relationship and circumstance have high disagreement even when the SHR reports an offender, and that the most important covariate of this is time to close the homicide investigation with an arrest. Research implications of the results are discussed.     

A case of stalking in the workplace and subsequent sexual homicide

A case of stalking in the workplace and subsequent sexual homicide by a 33-year-old male is reported. Following several months of stalking a 38-year-old female, the male subject went to the woman's office after business hours and restrained, raped, and murdered her. The cause of death was multiple stab wounds. The facts of the case reveal that the subject fits a predatory-type stalker, which represents a small subgroup within stalkers that has received little attention. Unlike other types of stalkers, the predatory stalker gives little warning to their victim (or multiple victims), as their stalking behaviors tend not to be very invasive or harassing. In general, most stalkers are not physically violent; however, predatory-type stalkers, given their tendency for sexual violence, are dangerous and the importance of identifying them is emphasized. Factors associated with perpetrators of sexual homicide are discussed.     

A Comparison of Ideologically-Motivated Homicides from the New Extremist Crime Database and Homicides from the Supplementary Homicide Reports Using Multiple Imputation by Chained Equations to Handle Missing Values

This study took advantage of the new open-source Extremist Crime Database (ECDB) to overcome obstacles to studying domestic far-right terrorism from a criminological perspective. In the past, exclusive definitions and inclusion criteria have limited available data on violent crimes committed by domestic far-right terrorists, and official data on violent crimes fail to capture offenders’ links to domestic far-right terrorism and ideological motivation (e.g., anti-government, anti-abortion, anti-religion). Therefore, little is known about the nature of far-right terrorist violence and how such violence is similar to and different from routine or more common forms of violence. Focusing on homicides, this study addressed why and how open-source terrorism data and official crime data can be comparatively analyzed. In doing so, we also demonstrate the utility of synthesizing terrorism and official crime data sources. Data on 108 far-right terrorist homicides were taken from the ECDB. Data on 540 common homicides (five comparison homicides for each far-right terrorist homicide) were randomly sampled from the 2000 Supplementary Homicide Reports. Using multiple imputation by chained equations and logistic regression, we imputed missing values and estimated models to compare the two homicide types on 12 different victim, offender, and event characteristics. Relative to common homicides, we found that far-right terrorist homicides were significantly more likely to have white offenders, multiple victims, multiple offenders, and to occur between strangers, and they were significantly less likely to have white victims, to be carried out with a firearm, and to occur in cities with more than 100,000 residents.     

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.     

An analysis of Korean homicide crime-scene actions

Recent studies have focused on how different styles of homicides will be reflected in the different types of behaviors committed by offenders at a crime scene. It is suggested that these different types of behaviors best be understood using two frameworks, expressive/instrumental aggression and planned/unplanned violence, to analyze the way the offender acts at the crime scene. Multidimensional analysis is carried out on the crime-scene actions of 70 Korean homicides. The proposed frameworks are found to be a useful way of classifying homicide offenses, assigning 80% of homicides to a dominant theme. Results also indicate that behavioral differences can be related to the differences in the offender-victim relationship. Finally, implications and suggestions for future research are discussed.     

Discovery,assessment and reconstruction of homicide with photographs of the murder

Report on a case in which photographs of the murder were the first hint pointing to homicide. Due to the advanced decomposition of the body the photographs were essential for the reconstruction of the homicide, in particular for the differentiation of the intravital injuries against postmortem lesions and the chronological order of the acts of violence.     

Homicide as Infectious Disease: Using Public Health Methods to Investigate the Diffusion of Homicide

This study examined the spatial and temporal movement of homicide in Newark, New Jersey from January 1982 through September 2008. We hypothesized that homicide would diffuse in a similar process to an infectious disease with firearms and gangs operating as the infectious agents. A total of 2,366 homicide incidents were analyzed using SaTScan v.9.0, a cluster detection software. The results revealed spatio-temporal patterns of expansion diffusion: overall, firearm and gang homicide clusters in Newark evolved from a common area in the center of the city and spread southward and westward over the course of two decades. This pattern of movement has implications in regards to the susceptibility of populations to homicide, particularly because northern and eastern Newark remained largely immune to homicide clusters. The theoretical and practical implications of the findings, as well as recommendations for future research, are discussed.     

凶杀案件主体责任能力评定影响因素分析

目的探讨20年来凶杀案件主体(被鉴定人)责任能力评定中的影响因素。方法将1985~2004年288例凶杀案件资料分成A期(1985~1989年)、B期(1990~1997年)和C期(1998~2004年),用SPSS 11.0统计软件进行相关分析和逐步判别分析,筛选出对责任能力评定有重要影响的判别因子。结果A、B、C期责任能力的相关因素稍有差异,但均与作案动机、自我保护能力、医学诊断、情感障碍、行为障碍、自知力障碍、辨认能力和控制能力呈显著相关(P<0.01)或相关(P<0.05)。A、B、C期责任能力的判别因子也不尽相同,环境辨认、危害行为的突然性、自我保护能力和自知力障碍为A期责任能力评定的判别因子;案前先兆、作案动机、环境辨认、自我保护能力、情感障碍、自知力障碍、医学诊断、感知障碍和思维障碍为B期的责任能力评定的判别因子;作案动机、自我保护能力、情感障碍和自知力障碍为C期责任能力评定的判别因子。结论影响A、B、C期凶杀案件主体责任能力评定的因素有所差异,“动机论”对责任能力评定的影响较大。     

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.     

An unusual case of child abuse homicide/suicide

This case report examines a child abuse homicide in which the perpetrator committed suicide a few hours after the infant's death. At the time of the perpetrator's suicide he was not under investigation, nor was he a suspect in the death of the child. Although the literature does not contain reports of similar cases, we are sure they exist. This report raises the question of the degree of social stigma attached to the accusation of child abuse. It also serves as a warning to those who must deal with the potentially suicidal child abuser.     

The impact of population heterogeneity and income inequality on homicide rates: a cross-national assessment

The current research produces regression models with sample sizes from 127 to 131 by initially employing a data set of 170 nations. The current study finds that ethnic heterogeneity and linguistic heterogeneity lead to higher homicide rates. However, religious heterogeneity has no impact on homicide rates. The present article also tests an interaction effect between population heterogeneity and income inequality. Unlike J. R. Blau and Blau (1982) and Avision and Loring (1986) proposition, the interaction term is not related to national homicide rates. The current study also discusses the theoretical implications of those findings.     

An analysis of a prehistoric homicide from northern California

An analysis was performed on a prehistoric human vertebral column recovered during an archaeological excavation in the Sierra of northern California. Fifteen burials believed to represent the Maidu culture of 400 to 700 years ago were recovered. The vertebral column from one of the individuals is particularly significant because of three embedded projectile points. The analysis attempts to recreate the trajectory of each point; to determine the possible extent of damage done by each with emphasis upon which could have been fatal; and by employing available ethnographic and archaeological data, to suggest the possible circumstances surrounding the violent event. The conclusion suggests that death may have resulted from any of the three wounds and was probably the result of an intratribal dispute.     

Families of Homicide Victims: Service Utilization Patterns of Extra- and Intrafamilial Homicide Survivors

Homicides precipitate numerous problems for victims' families that can be eased, in part, by counseling, case management, and court advocacy services. Guided by a crisis theory framework, the records of 112 homicide victims' family members (or survivors) served by a public victims assistance agency were examined to discern typical service utilization patterns and differences for survivors of intrafamilial homicides (i.e., cases in which the perpetrator was a family member of the victim). Results indicated that survivors of intrafamilial homicides utilized services during the initial 8-week crisis period following the homicide more than other survivors, yet used services less during the subsequent 8-week period. The findings substantiated the application of crisis theory to studying the experiences of survivors and underscored the importance of considering survivors' familial relationships to perpetrators in the provision of services.     

Homicide in the elderly. A study of homicide in the aged based on an Aachen autopsy sample of the 10-year period 1976-1985

Investigations on the peculiarities of homicides of the elderly are missing in the German literature up to the present date. Therefore we undertook an evaluation of the case files collected at the Aachen Institute of Forensic Medicine from the ten-year-period 1976-1985. Among 3736 autopsies we found 183 cases of homicide with 35 victims of 60 years and older. We collected peculiarities of modus operandi related to victim, suspect and offence and compared the data with such from police criminal statistics and partially with German population statistics. Two types of homicide of the elderly can be differentiated: One is independent of the victim's age whereas the other exploits the living conditions in the higher age (living alone, socially isolated, ailing, helpless etc.) For these latter cases the name "Gerontocide" is proposed. The paper deals with the peculiar difficulties of criminal investigation and clarification in such cases, resulting on the one hand from the lack of suspicion if elderly people die, on the other hand from the more difficult detection of causal relationship between offence and death--especially in the presence of severe illness of the victim.     

Southernness, migration, and homicide risk: An analysis of individual-level data

The regional culture of violence literature has neglected the effect migration out of the South has on individual-level homicide risk. The present paper tests the hypothesis that moving away from the South reduces exposure to a relatively large class of motivated offenders and lowers the risk of homicide victimization to non-Southern levels. The data come from the National Mortality Detail File and include 2,647 homicides and 403,184 natural deaths. A multivariate logistic regression analysis shows that migration out of the South does not normalize homicide risk. Thus, former Southerners continue to remain at a relatively high risk of homicide victimization in spite of relocating to a safer environment. An earlier version of this paper was presented at the annual meeting of the Academy of Criminal Justice Sciences, Albuquerque, New Mexico, March 1998. Data were provided by the Inter-University Consortium for Political and Social Research.     

Reducing homicide: A review of the possibilities

This paper explores the potential for reducing homicide, with a particular focus on the United Kingdom. It draws upon data from the Homicide Index, international research on homicide, and the general crime reduction literature. Homicide is highly diverse in its characteristics, causes and dynamics, so effective strategies to reduce it are likely to require tailoring to specific forms. The paper focuses upon four important categories: domestic (partner) homicide; the killing of infants; alcohol-related homicide; and homicide involving guns and knives. Attention is also paid briefly to issues around dangerous offenders and mental disorder, and to homicide victimisation in relation to specific occupations.This paper was written in 2001 and accepted for publication by Crime Law and Social Change in 2002. Some minor updating has been undertaken by the authors, but due to the delay some sections will inevitably not refer to the most recent research. An earlier version of the paper was published online by the Home Office in 2003.     

Beyond the Social Production of Homicide Rates: Extending Social Disorganization Theory to Explain Homicide Case Outcomes

This paper examines the intersection of social disorganization at a community level with responses to crime. In contrast to other works examining the impact of social disorganization on the production of crime rates, we examine the role of social disorganization theory in responses to crime rates (i.e. the arrest and conviction of perpetrators of crime). In an effort to examine these dynamics, we use law enforcement data from Cleveland, Ohio to explore the role of social disorganization in the ability of police and the courts to respond to homicide cases. Such an examination suggests not only how far the law extends in community responses to homicide but also reveals an extension of social disorganization theory beyond its established role in explaining the production of crime rates.
