A systematic review of the literature comparing male non-serial sexual killers and sexual aggressors: examining homogeneous and heterogeneous characteristics of these groups

ABSTRACT

This systematic review considers what is known about the characteristics of sexual killers and sexual aggressors. The aim was to identify which characteristics have consistently been shown to be similar (homogeneous) and which are different (heterogeneous) across these two groups. Ten studies, including approximately 300 sexual killers, were analysed. Only studies where the samples were directly compared and where sexual killers were male, predominantly non-serial and perpetrated against adult female victims were included. Results indicate that levels of loneliness and anger appear to be more prevalent in the sexual killer sample while mental health disorders, criminal history, family structure and history of sexual abuse as well as some crime scene behaviours seem to be similar across the two groups. The results of this review have also highlighted some methodological problems inherent to these types of studies and these issues are discussed from the perspective of improving research on these crimes.     

Dating Violence Victimization,Relationship Satisfaction,Mental Health Problems,and Acceptability of Violence: A Comparison of Men and Women

Two of the most common reported consequences of dating violence are its impact on the victim’s satisfaction with their romantic relationship and its impact on the victim’s mental health. Recent research suggests that the strength of these relationships may be moderated by the degree to which the dating violence is acceptable to the victim. However, studies of these relationships have been limited to samples of women. The purpose of the present research was to examine the relationships among dating violence victimization, relationship satisfaction, mental health problems, and acceptability of violence for a sample that includes not only female victims, but also male victims. Using a sample of 155 male and 417 female college students, hierarchical regression analyses found that dating violence victimization is associated with relationship satisfaction and mental health problems for both men and women. For men, acceptability of violence moderated the relationship between dating violence victimization and the mental health problems of depression, anxiety, and somatization. For women, acceptability of violence moderated the relationship between dating violence victimization and relationship satisfaction only.

REASSESSING RACE DISPARITIES IN MARYLAND CAPITAL CASES*

A generation of research studies that were conducted in multiple states and covered different time periods has found evidence that individuals who kill white victims encounter a greater risk of facing the death penalty than killers of black victims. More recently, research has also examined the likelihood of death penalty processing for black defendants who kill white victims in comparison with other defendant–victim race groups. In particular, a study in Maryland conducted by Paternoster et al. (2003) found evidence that offenders in black defendant–white victim cases were more likely to be death noticed by prosecutors and to receive a death sentence than other offenders. A recent analysis by Berk, Li, and Hickman (2005) raised questions about some of these findings. In this article, we conduct new analyses and conclude that black defendants who kill white victims face a greater risk of adverse treatment than other types of defendants.     

The violent female perpetrator and her victim

The aim of the present study was to examine the relationship between violent female offenders and their victims as well as the putative differences in the motives and specific psychological factors among three groups of female offenders: women who have victimised someone closely related to them, those who have victimised an acquaintance and lastly women who have victimised a stranger. More than half (N=61) of all violent female offenders hospitalised or incarcerated in Finland during the year of study were interviewed and assessed by Structured Clinical Interview II for DSM-IV (SCID-II) and Hare's Psychopathy Checklist-Revised (PCL-R). In 34% of the cases the victims were persons close to the offender, in 41% the victims were acquaintances and in 25% strangers. The victims in homicide offences were more often both male and closer to the perpetrator than in assault offences. Although motives were related to interpersonal problems, self-defence and long-term physical or psychological abuse were reported by only a few women, even for the small proportion of women whose victims were intimate partners. The most frequent reason for offences stemmed from confrontational situations in connection with alcohol use. Women who victimised acquaintances and strangers were also more likely to have a history of criminality and substance abuse than women who victimised those in close personal relationships. The latter were also more likely to have an antisocial personality disorder (PD) and psychopathic characteristics. There were, however, no significant differences found between those who had experienced physical or psychological abuse in childhood or adulthood and those who had no adverse experiences. These findings suggest that the violent behaviour by females leads more often to the death of the victim, when the victim is closely related to the perpetrator. The commonly-held view that violent female offending occurs primarily as a consequence of precipitation by the victim was not supported.     

Homicide-suicide (dyadic death), homicide, and firearms use in England and Wales

Homicide-suicide forms a distinct form of homicide. An analysis of cases in the Yorkshire and Humberside region of England between 1991 and 2005 revealed 37 episodes with 42 victims. Previous studies have shown a high rate of use of firearms. Over the last 2 decades firearms legislation has become more restrictive. In this study all assailants were male, mean age 46.8 years. The commonest method of homicide was strangulation (36%) with 16% killed by firearms. This is a reduction compared with a previous study in the same region. All killers who shot their victims killed themselves with firearms. There were no multiple killings with firearms in this study and no stranger killings. Hanging was the commonest method of suicide. During the same period the use of firearms as a method of homicide increased in England and Wales with handguns, the most common weapon. Nationally, suicide after homicide has remained at a similar rate over the half century and is an uncommon phenomenon. Firearms use remains low in both homicide and homicide-suicide episodes in England, and further analysis is required to determine changes in patterns of killing.     

Sex-symmetric effects of coercive behaviors on mental health? Not exactly

The present study tested a section of the model of coercion in intimate partner violence (IPV) by investigating the relationships among coercion, IPV and mental health symptoms. The study's sample consisted of 573 culturally diverse university students (age M = 21.4) who completed a survey that measured past IPV victimization, coercive behaviors, and mental health symptoms. Structural equation modeling analyses revealed that coercion was a stronger predictor of adverse mental health symptoms than was IPV victimization. In addition, the study found that the adverse effect of coercive behaviors on mental health symptoms was stronger among female victims of IPV than among male IPV victims. The results have implications for theory building, future research, and mental health professionals who work with female and male victims of IPV.     

Effects of victim gender,victim sexual orientation,victim response and respondent gender on judgements of blame in a hypothetical adolescent rape

Objectives. Few studies have examined the judgements made towards adolescent rape victims, and none have investigated attributions towards gay male or lesbian adolescents. The current study examined the effects victim gender, victim sexual orientation, victim response, and respondent gender, on attributions of blame in the depicted rape of a 15‐year old adolescent. Methods. A total of 164 respondents read details of this assault before completing 15 attribution judgments. Results. Respondents were expected to attribute more blame to a victim who was male, gay, and who failed to resist the perpetrator. Male respondents were also expected to be more blaming of the victim than females. Overall these hypotheses were supported. Conclusion. Results are discussed in relation to the role gender stereotypes and homophobia play within attributions blame in sexual assault cases. Specifically, it seems male adolescent rape victims are subjected to the same negative stereotypes as male adult victims. Implications and ideas for future research are considered.     

Sexual assault nurse examiners' perceptions of their relationship with doctors, rape victim advocates, police, and prosecutors

In response to the negative and inefficient treatment of rape victims by emergency room personnel, the first Sexual Assault Nurse Examiner (SANE) programs began in the late 1970s. While SANEs, doctors, rape victim advocates, police officers and prosecutors work together to ensure the most comprehensive and sensitive care of rape victims, they all have very different roles and objectives. This research explores SANEs' perceptions of their relationships with other professionals who treat or interact with rape victims. Data from interviews with 39 Sexual Assault Nurse Examiners from four East Coast states indicate positive relationships are marked by open communication, respect shown towards SANEs as well as rape victims, and a sense of appreciation among SANEs. On the contrary, negative relationships result when SANEs believe police treat victims poorly, when advocates overstep boundaries and question SANEs about evidence collection or the exam, and when prosecutors fail to properly prepare them to testify during a trial.     

Appropriately Upset? Emotion Norms and Perceptions of Crime Victims

Victims who express less emotion in response to a crime are perceived as less deserving, less sympathetic, and they have less punishment assigned to the offender who committed the crime. This study considers the extent to which emotion norms underlie perceptions of victims who testify. Two studies investigate the circumstances in which emotional reactions to a crime are seen as "unusual" and whether a more general emotion norm underlies responses to victim testimony. We test a "victim-role" norm against a "proportionality" norm by crossing the severity of victim's emotional response (severe or mild) with the seriousness of a crime (serious or less serious). Results across two studies lend greater support to the notion that people expect victims to match the intensity of their emotional response to the seriousness of the event (i.e., a proportionality rule), although we also find instances in which expectations of the victim are not strong. Gender of the victim exhibited small and contingent effects. We discuss the relevance of emotion norms to legal settings.     

Dismemberment and Mutilation: A Data-Driven Exploration of Patterns,Motives, and Styles

Classification of violent behavior, including dismemberment and mutilation, has become increasingly more significant. This study uses a data-driven classification system based upon knowledge drawn from the pertinent literature, and examination of cases of offenders who have dismembered or mutilated their victims. The latter were extracted from the Serial Killer Database, as well as media sources, and assessed for characteristics of the perpetrators and victim(s). An informational form was developed and used to establish quantitative parameters and objectively extract pertinent information that could be used for comparison and pattern analysis. Motives and styles, as well as the organized/disorganized dichotomy for murder and dismemberment/mutilation, were examined for each case. The majority of cases demonstrated defensive styles (60%), with the second most common being offensive styles (26%), which differs from previous studies that do not exclude older cases. Additionally, 68% of cases reflected organized patterns for both murder and the acts of dismemberment or mutilation. The results support a data-driven classification system that may serve as a foundational model for the investigation of specific motives of this type of deviant behavior in future research.     

Managing victim status in group therapy for men: a discourse analysis

In contrast to the abundance of research on women victims, this article sheds light on the discourse of men who are self-identified as victims of their female partners' abuse. The purpose of this study was to investigate the most salient identity constructions and abuse conceptualizations among participants of group psychotherapy for men who have been abused in intimate, heterosexual partner relationships (i.e., Calgary Counselling Centre's 14-week group program titled "A Turn for the Better"). The men's identity work was examined using the methods and theoretical perspective of discourse analysis. Analysis of the talk demonstrated that the group agenda was to work through the ambiguity of abuse in the service of having the men identify themselves as victims. Thus, both the men and the group facilitators actively constructed "true victim" subject positions through their resistance to commonsense orientations of (a) "men as perpetrators" and (b) whether abuse consisted of more than physical violence. The therapeutic language of resistance was a common strategy used to manage victim status but also required further negotiation as it entailed a component of abuse (i.e., risked positioning the men as abusers rather than victims). The discussion focuses on how these findings may differ from the identity work present in women victim therapeutic groups. In addition, we note that it is difficult to uphold the victim-versus-perpetrator dichotomy in therapeutic discourse.     

Victim age,attractiveness and,abuse history as factors in the perception of a hypothetical child sexual abuse case

Abstract

This study examines the effect of victim age, victim attractiveness, the victim's abuse history and respondent gender have on attributions of blame and credibility towards a female victim in a hypothetical child sexual abuse case. A total of 397 respondents from a community sample read a hypothetical child sexual abuse (CSA) scenario in which victim age, victim attractiveness and the victim's abuse history were manipulated. Respondents then completed a 16-item blame attribution questionnaire. Several predictions were made. First, a 10-year-old victim would be deemed less blameworthy and more credible than a 15-year-old victim. Secondly, an attractive victim would be viewed more positively, and attributed less blame, than an unattractive victim. Thirdly, a victim with previous history of being sexual abused—either by the same or different perpetrators—would be deemed more culpable for their own CSA than a first time victims. Finally, female respondents were expected to take a more pro-victim and anti-perpetrator stance than males. Whilst comparatively few differences were found across victim attractiveness and abuse history. Overall findings were broadly in line with predictions. It was concluded that victim age and respondent gender play particularly important roles in the attribution of blame towards victims and perpetrators of child sexual abuse.     

Victim age and capital sentencing outcomes in North Carolina (1977–2009)

Age is prominent among theories of criminology and victimology. It is less conspicuous in punishment theory, despite its emphasis in retributive theory and lawmaking. The present study evaluated competing ‘years of life lost’ and ‘vulnerable victim’ hypotheses to examine the influence of victim age in capital sentencing decisions. Using case file data on the population of capital murder trials in the State of North Carolina (1977–2009), our findings produce mixed results. Our quantitative analyses suggest that death sentences are significantly less likely in direct proportion to victim age. Killers of elderly victims are less likely to receive the death penalty; conversely, the odds of a death sentences are slightly greater for killers of child victims. Supplementary qualitative analyses suggest that while many child and elderly victims were not per se ‘vulnerable,’ a substantial subset of each clearly were treated as such. We discuss implications for vulnerable victim research and the role of quasi-legal factors in case outcomes.     

Asphyxial homicide in two Scandinavian capitals

In the Oslo and Copenhagen capital areas, 94 asphyxial homicides were committed in the 10-year period 1985-1994, accounting for 22% of all homicides in that period. Sixty-nine (73%) of the asphyxia victims were female. The most common method of asphyxiation was manual strangulation. Seventeen (18%) of the victims were below the age of 10, accounting for 59% of all homicides in that age group. Whereas 38% of the female victims were killed by their spouse, this was the case for only one male victim. The motive was not known in a great proportion of cases. Fifty-seven percent of the victims had been subjected to additional violence, and in this respect there was no difference between the sexes. In 12 of the cases the offender was female; in 9 such cases the victim was her offspring. More than half of the victims had no blood alcohol. When disregarding the victims less than 10 years of age, 33% of the male and 49% of the female victims had no blood alcohol. The crime scene was the victim's domicile among 72% of female and 52% of male victims. Forty-two percent of the female and 11% of the male victims above the age of 10 years were married or cohabitant.     

What Distinguishes Single from Recurrent Sexual Victims? The Role of Lifestyle‐Routine Activities and First‐Incident Characteristics

An unsettling reality is that a substantial proportion of women who have been sexually victimized are recurrent victims who experience more than one sexual victimization while young adults. What is not well understood is why some women experience a single sexual victimization whereas others experience recurrent sexual victimizations. Using a sample of 4,399 college women from the National College Women Sexual Victimization study, we examine lifestyle‐routine activities and first‐incident characteristics that could place women at risk of being recurrent sexual victims during an academic year. Our results show that none of the lifestyle‐routine activities variables differentiated single and recurrent victims; the factors that predicted being a single victim are similarly predictive of being a recurrent victim. However, women who used self‐protective action during the first incident reduced their likelihood of being a recurrent victim. Implications for the development of sexual victimization risk‐reduction and prevention programs are also discussed.     

Homicide by sharp force in two Scandinavian capitals

In the Oslo and Copenhagen capital areas, 141 homicides by sharp force were committed in the ten-year period 1985-1994. This method accounted for 33% of the homicides in this period. Thirty-five percent of the victims were female, and most of the victims were between 20 and 50 years of age. The majority of the male victims were killed by an acquaintance, the females by their spouse. Sixty-five percent of the male and 37% of the female victims had alcohol in their blood. The majority of the female victims had lesions in 3-4 anatomical regions, while the males most often had lesions in only one anatomical region. Seventy-nine percent of the females and 36% of the males had self-defence injuries in the upper extremities. In 21 cases (15%) the offender was a woman, 19 of their victims being male; the weapon in these cases was most often a kitchen knife. Seventy-eight percent of the females and 49% of the males were killed in their own home. The most common circumstance was family row when the victim was female, while a fight was the most common circumstance when the victim was male. Three offenders committed suicide after having committed homicide(s) (seven victims; three offenders).     

Factors related to suicide in New York state prisons

OBJECTIVE: Examine factors related to prison suicides to aid prevention. METHOD: Review the mental health records of all 76 suicides that occurred between 1993 and 2001 in New York State Department of Correctional Services (NYSDOCS) prisons that had some contact with mental health services during their incarceration. (This represented 84% of all NYSDOCS suicides.) Extract data from the psychological autopsies for a sample of 40 of these suicides. RESULTS: Of the suicide victims with some mental health contact, 95% had a substance abuse history, 70% displayed agitation or anxiety prior to the suicide, and 48% had a behavioral change. Common stressors preceding the suicide were inmate-to-inmate conflict (50%), recent disciplinary action (42%), fear (40%), physical illness (42%), and adverse information (65%) such as loss of good time or disruption of family/friendship relationships in the community. Forty-one percent had received a mental health service within 3 days of the suicide. Compared to the about 7200 inmates actively receiving mental health services in state prison, African-Americans and patients with a Major Mood (Bi-polar or Major Depression) were under-represented. Adjustment Disorder, Schizophrenia, and Personality Disorder diagnoses were over-represented. Suicide victims were more likely to have been incarcerated for a violent crime. CONCLUSION: Mental illness, anxiety/agitation, behavior change, stressors, history of substance abuse, and non-African-American were important risk factors.
