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 a Police/Victim Assistance Crisis Team Approach to Domestic Violence

A police/victim assistance crisis intervention program was evaluated over a 6-month period for its effect on police-related outcomes. Police report data on crisis team cases (N = 96) were compared to a random selection of family violence cases (N = 80) that were not served by the crisis team. The crisis team cases generated more arrests; however, victim cooperation was lower than in noncrisis intervention cases. Implications for work with family violence and victim assistance are discussed, as well as needs for future research.     

Domestic violence: A national study of the nature, size and effects of domestic violence in the Netherlands

This article reports on a large-scale nation-wide study conducted by Intomart among 1,000 randomly selected Dutch adults (male and female) about their experiences with domestic violence. An important goal of the survey was to generate general information on domestic violence. It turns out that nearly half of the Dutch population (45%) has at one time been a victim of some form of non-incidental domestic violence. It was also demonstrated that both men and women become victims of domestic violence, and the high percentages of victimization during childhood are particularly striking. Furthermore, it turned out that domestic violence often involves a combination of physical, mental and sexual forms of violence.     

Juvenile and Adult Offenders Arrested for Sexual Homicide: An Analysis of Victim–Offender Relationship and Weapon Used by Race*

Abstract: Limited information is available on racial offending patterns of sexual homicide offenders (SHOs). This study used a 30‐year U.S. Supplementary Homicide Reports sample of SHOs arrested in single‐victim situations (N = 3745). The analysis strength was used to determine whether the findings yielded meaningful patterns for offender profiling. Several important findings emerged for the juvenile offenders. Juvenile White SHOs were likely to target victims with whom they shared a mutual relationship. In contrast, Black juveniles were equally likely to murder strangers and those with whom they had prior and familial relationships. Notably, no juvenile Black SHOs were arrested for murdering intimate partners. Juvenile White SHOs were twice as likely to use edged weapons as their Black counterparts. Black juveniles, conversely, were more likely than White juveniles to use personal weapons. Beyond these findings, known victim–offender relationships and weapon used may not have significant utility for investigators in identifying the SHO race, even after controlling for offender age. Limitations and future directions are discussed.     

The Prediction of Young Homicide and Violent Offenders

Aim was to investigate a range of potentially modifiable risk factors for boys in late childhood for later violence and homicide convictions. Boys from the Pittsburgh Youth Study (N = 1,517) were measured through self-reports and official records in late childhood (ages 11–13) on a large number of potentially modifiable risk factors, and were followed up in juvenile and adult criminal records in terms of violence and homicide. Predictors of conviction for homicide largely overlapped with predictors of conviction for violence. Twenty three out of 28 possible risk factors significantly predicted later violence convictions. Regression analysis identified four significant modifiable risk factors in late childhood for any violent offenders: physical abuse, parental stress, bad friends and low school motivation. The higher the number of early risk factors, the higher the probability of later conviction for violent offenses including homicide. The discussion focus on single-, and multi-modal interventions in late childhood to reduce later violence and possibly homicide.     

From Victim to Offender: The Effects of Male Initiated Violence on Women Arrested for Using Intimate Partner Violence

A number of theorists posit that most women who are arrested for using violence against their intimate partners are in-fact victims of IPV themselves and should be treated as such. However, in this population of women IPV arrestees empirical investigation has yet to explore how physical and emotional victimization experiences are associated with arrest related factors, propensity to be abusive or attitude toward using relationship violence. The current study explores these factors finding no difference in arrest factors between women who (a) deny abuse, (b) report rare/occasional abuse and (c) report frequent/very frequent abuse. However, mixed results were found with regard to participants’ responses on scales measuring propensity to be abusive and attitudes about using violence in marriage. Theoretical and practical related issues are addressed.     

An Empirical Analysis of 30 Years of U.S. Juvenile and Adult Sexual Homicide Offender Data: Race and Age Differences in the Victim–Offender Relationship

Abstract: Little is known about the racial patterns of crimes committed by sexual homicide offenders (SHOs). This study examined race and age influences on victim–offender relationship for juvenile and adult SHOs. A large sample (N = 3868) from the Supplemental Homicide Reports (1976–2005) was used. Analyses of victim–offender patterns included examining victim age effects (child, adolescent, adult, and elderly). The findings revealed several race‐ and age‐based differences. Black offenders were significantly overrepresented in the SHO population. This finding held for juveniles and adults independently. White SHOs were highly likely to kill within their race, “intra‐racially” (range 91–100%) across four victim age categories, whereas Black SHOs killed both intra‐racially (range 24–82%) and inter‐racially (18–76%), with the likelihood of their killing inter‐racially increasing as the age of the victim increased. This study underscores the importance of considering victim–offender racial patterns in sexual murder investigations, and it offers practical implications for offender profiling.     

From Victim to Offender: Female Offenders of Child Sexual Abuse

Historically, women have been seen to have a much lower recorded rate of crime than men. In the area of child sexual abuse, women have figured prominently in official statistics as victims but have had virtually no official recognition as offenders. It is difficult for many people to accept that women do sexually abuse children and this can result in discounting by personnel in child protection services and police. This article discusses female offenders of child sexual abuse and the way in which these cases are processed by the criminal justice system.     

The Unusual Victim: Understanding the Specific Crime Processes and Motivations for Elderly Sexual Homicide

Sexual homicides involving elderly victims are rare and unusual crimes, and research specifically focusing on these homicides is almost inexistent. The current study investigates the crime commission process as well as the motivations underlying elderly sexual homicides. The sample comes from the Sexual Homicide International Database (SHIelD) including sexual homicide cases from Canada and France. A total of 56 cases involving victims aged 65 years or more were compared with 513 cases involving victims aged between 16 and 45 years old. Bivariate analyses and two-step cluster analysis are performed. Findings show major differences in the crime commission process of the two groups of offenders. We also identified a four-cluster typology of elderly sexual homicide offenders based on their motivations (sexual, robber, sadistic, experimental). Although sexual homicides involving elderly victims are rare, these crimes are different, presenting specificities and should be studied as a group on its own.     

Examining the relationship between sexual offenders and their victims: Interpersonal differences between stranger and non-stranger sexual offences

Abstract

The present study examined the behavioural differences in sexual assault offences in relation to the offender–victim relationship (stranger versus non-stranger). These differences were examined specifically in the context of four interpersonal themes of interaction: dominance, submission, hostility and cooperation. The details of 100 sexual offence cases (50 stranger and 50 non-stranger) were content-analysed, generating 58 dichotomous variables, covering offender and victim behaviour during the offence. χ² tests comparing the two samples found that offenders who were strangers to their victims were more likely than non-stranger offenders to display behaviours that indicate a hostile, violent offence style. In contrast, those offenders who knew their victims were more likely than strangers to display a less violent and more personal, compliance-gaining offence style. These findings are discussed in terms of their implications for offender rehabilitation and victim support.     

Education and Marriage as Protective Factors Against Homicide Mortality: Methodological and Substantive Findings from Moscow

This study examines the protective effects of education and marriage against homicide mortality in Russia. Individual data are obtained from death records and population data from the 1994 micro-census, and differentials in mortality from homicide are estimated employing two different methods: a straightforward approach using census data and proportional mortality analysis. We find that the latter underestimates the impact of education on homicide mortality. Despite differences in effect sizes, however, both methods reveal a significantly higher risk of homicide victimization for those that are unmarried and less educated. We conclude that education and marriage likely provide social capital and coping skills that protect individuals against violent victimization, even during times of dramatic social change and dire economic circumstances such as those faced in transitional Russia.

The Institution of a Standardized Investigation Protocol for Sudden Infant Death in the Eastern Metropole,Cape Town,South Africa,,

The rate for the sudden infant death syndrome (SIDS) in Cape Town, South Africa, is estimated to be among the highest in the world (3.41/1000 live births). In several of these areas, including those of extreme poverty, only sporadic, nonstandardized infant autopsy, and death scene investigation (DSI) occurred. In this report, we detail a feasibility project comprising 18 autopsied infants with sudden and unexpected death whose causes of death were adjudicated according to the 1991 NICHD definitions (SIDS, n = 7; known cause of death, n = 7; and unclassified, n = 4). We instituted a standardized autopsy and infant DSI through a collaborative effort of local forensic pathology officers and clinical providers. The high standard of forensic investigation met international standards, identified preventable disease, and allowed for incorporation of research. We conclude that an effective infant autopsy and DSI protocol can be established in areas with both high sudden unexpected infant death, and elsewhere.

Female Sex Offenders: A Controlled Comparison of Offender and Victim/Crime Characteristics

The current study was a chart review of 31 female sex offenders (FSO), 31 male sex offenders (MSO), 31 female violent offenders (FO), and 31 male violent offenders (MO) using a 2 (female or male) by 2 (sex or violent offender) design. This is the first known study to employ three control groups when researching female sex offenders. Multiple variables appeared related to gender and crime. However, some variables emerged as FSO specific. They reported the least alcohol abuse history and had fewer admissions of guilt to the crime than the two violent offender samples. More FSOs knew their victim and were biologically related to their victim than MSOs. Lastly, the FSO sample was the least discriminating as to their victim’s gender and had the highest overall rate of sexual victimization.     

A history of the use of the concept of parental alienation in the Australian family law system: contradictions,collisions and their consequences

ABSTRACT

This paper presents insights into the history and current deployment of the concept of parental alienation in the Australian family law system. It begins in 1989, when an article on parental alienation syndrome was first published in an Australian law journal. It then traces aspects of the socio-legal and social science research, gender politics, law reform and jurisprudence of the following 30 years, paying attention to moments of significant change. The impacts of major amendments that emphasise the desirability of post-separation shared parenting outcomes in 1996 and 2006 are specifically considered. More recently, in 2012, reforms intended to improve the family law system’s response to domestic and family violence were introduced. The history reveals an irreconcilable tension between the ‘benefit’ of ‘meaningful’ post-separation parent-child relationships and the protection of children from harm. When mothers’ allegations of violence in the family are disbelieved, minimised or dismissed, they are transformed from victims of abuse into perpetrators of abuse – alienators of children from their fathers. Their actions and attitudes collide with the shared parenting philosophy. This is arguably an inescapable consequence of a family law system that struggles to deal effectively with family violence in the context of a strong shared parenting regime.     

U.S. child custody outcomes in cases involving parental alienation and abuse allegations: what do the data show?

ABSTRACT

Family court and abuse professionals have long been polarized over the use of parental alienation claims to discredit a mother alleging that the father has been abusive or is unsafe for the children. This paper reports the findings from an empirical study of ten years of U.S. cases involving abuse and alienation claims. The findings confirm that mothers’ claims of abuse, especially child physical or sexual abuse, increase their risk of losing custody, and that fathers’ cross-claims of alienation virtually double that risk. Alienation’s impact is gender-specific; fathers alleging mothers are abusive are not similarly undermined when mothers cross-claim alienation. In non-abuse cases, however, the data suggest that alienation has a more gender-neutral impact. These nuanced findings may help abuse and alienation professionals find some common ground.     

Long-Term Follow-Up of Young Children Placed in Foster Care: Subsequent Placements and Exposure to Family Violence

This study examined the quality or characteristics of permanent placements at 6 years of age for 254 children who had been removed from their homes prior to attaining 3.5 years of age (mean = 13 months). Although the primary objective when removing children is protection, subsequent permanent placements are prioritized by federal legislation with a stable family environment, especially one with the biological parent(s), being preferred. Three a priori comparisons (i.e., reunified vs. nonreunified, adopted vs. foster care, relative vs. nonrelative foster care) were conducted for caregiver and child reports of exposure to family violence. The results indicate that both reunified children and their parents report more family violence (witnessed and child victimization) than do nonreunified children and their caregivers. Adoptive parents did report that they used more minor violence in disciplining their children than did foster caregivers, but their children reported witnessing significantly less physical violence in the home. Recognizing that the development of children removed from their homes because of maltreatment is likely a function of both the maltreatment as well as the quality of subsequent family experiences (i.e., violence exposure), implications of the findings for determining placements are discussed.     

The Relationship Behavior Networks of Young Adults: A Test of the Intergenerational Transmission of Violence Hypothesis

The purpose of this study was to determine how negative relationship behaviors are structured in the semantic networks of young adults from violent versus nonviolent homes. Participants included 110 students (72 females and 38 males) from a large Midwestern university who were enrolled in an introductory psychology class. They completed a sorting task that involved relationship behavior stimuli. As hypothesized, differences were found in the composite sorting patterns, as represented by multidimensional scaling (MDS) solutions, for three different groups categorized by their family-of-origin violence history (i.e., nonvictimized by/did not witness parental violence, None; victimized only, Victim; and both witnessed/victimized, Both). Interpretations of the MDS solutions revealed different associations between violent and nonviolent conflict behaviors for victimized versus nonvictimized individuals, suggesting different semantic associations for conflict for individuals in the two groups. In a second set of analyses, separate solutions were generated for perpetrating and nonperpetrating individuals from violent families. Perpetrator and nonperpetrator solutions were also found to differ significantly. These findings suggest that relationship-specific semantic networks are associated with both past and current experiences with violence. One interpretation of these findings is that cognitive differences, generated in the family of origin, may serve to perpetuate a cycle of violence in subsequent romantic relationships.     

A fatal interaction: The role of the victim and function of aggression in intrafamilial homicide

Abstract

This study examines the interaction between the victim and offender during intrafamilial homicide. It is hypothesised that in order to understand the fatal consequences of the interaction, a psychological model must take into account both the role of the victim, as either a significant person or non-significant object, and the function of the aggression, as either instrumental or expressive. The combination of these two proposed facets gives rise to four hypothesised styles of intrafamilial homicide. This hypothesis was tested by analysing 191 intrafamilial homicide cases from the Chicago HITS database. Fifty two crime-scene actions were analysed using Smallest Space Analysis which revealed four distinct thematic clusters of variables. These themes corresponded to the hypothesised facets of victim role and function of aggression. Two related to expressive acts, (a) those murders where the offender kills multiple members of his family and subsequently takes his own life, and (b) cases where the victim is not treated as a significant person in the interaction but is simply used as a target for the offender's rage. The other two relate to instrumental acts, (c) those murders that are a culmination of years of abuse in which the offender sees the killing as the only means of escape, and (d) homicides where the victim is seen as an obstacle to the offender achieving a goal and is removed.

A further test of the validity of these four themes in describing distinct forms of interaction within intrafamilial homicide was to examine the proportion of cases which could be classified according to the framework. The hypothesis that each relationship would map onto just one of the interactional styles was tested by χ² which confirmed that such exclusive relationships existed at the p < .001 level of significance. This has theoretical as well as practical implications in that in using this method of classification it may be possible to infer which family member is responsible for killing their relative.
