Comparing serial homicides to single homicides: A study of prevalence,offender, and offence characteristics in Sweden

Multiple and serial homicides constitute around 1.6% of all homicides but have unusually tragic outcomes. The aims of this study were to report the prevalence serial‐homicide offences and the characteristics of serial‐homicide offenders in a non‐North American context. The study included all convicted serial‐homicide offenders in Sweden from 1973 to 2012 (n = 25), as well as a population‐based control sample of single‐homicide offenders collected during 2007 and 2009 (n = 201). Similar to U.S. findings, approximately 1.6% of homicides could be attributed to serial‐homicide offenders. Serial offenders were more often diagnosed with personality disorders and autism‐spectrum disorders compared with single offenders; and serial offences more often involved victims who were female and unacquainted with the offender, as well as planning, sexual motives, and asphyxia as method of violence. One third of serial offences involved actions aimed at disguising the manner of death; such actions were considerably less common in single‐homicide offences. Few offenders displayed the traditional profile of a serial‐homicide offender; however, one third displayed sexual motives, a rate roughly 10 times higher than that in the single‐homicide group. The study concludes that serial‐homicide offenders should be subjected to forensic‐psychiatric examinations and that research involving cross‐contextual differences and similarities in serial‐homicide offenders is needed.     

Integrating flow theory and the serious leisure perspective into mental health counseling

This article explores how flow theory and the serious leisure perspective (SLP) can be integrated into mental health counseling. Although different counseling models have acknowledged the role of leisure in the counseling process, leisure is largely an unknown and superficial concept in the mental health counseling literature. Four broad-based pragmatic ideas regarding how flow theory and the SLP can be integrated into the counseling process include mental health counselors (1) understanding the concepts of serious leisure, casual leisure, project-based leisure, flow (enjoyment), and hedonistic pleasure; (2) becoming aware of various assessment instruments that measure flow and serious leisure; (3) using the provision characteristics of entering flow into the counseling process; and (4) empowering clients to becoming community change agents through serious leisure pursuit, resulting in flow experiences.     

South African Serial Homicide: Offender and Victim Demographics and Crime Scene Actions

There is an abundance of literature on serial homicide from a Western perspective that outlines operational definitions, types of offenders and how they prey upon their victims. However, currently, there is a lack of studies that compare serial homicide in different countries. The current study aims to give an overview of the demographics of serial homicide offenders and victims in South Africa and compare these to the demographics of offenders and victims from other currently available empirical studies of other countries. The sample consisted of 33 out of the total 54 solved series in South Africa between 1936–2007, which includes a total of 33 offenders, 302 victims, and 254 crime scenes. Results of the sample as a whole showed that South African serial homicide offenders are similar to offenders in other countries in terms of their actions at the crime scene and victim choice, with some notable exceptions. Additional analysis looked at the offender's consistency of targeting certain types of victims across their homicide series in comparison with the patterns of serial homicide offenders in other countries.

An examination of behavioral consistency using individual behaviors or groups of behaviors in serial homicide

Establishing behavioral consistency in serial homicide offending behavior is essential when linking homicides together and to a common offender. An examination of 35 serial homicide behaviors utilized by 90 offenders in 450 serial homicide cases was carried out to identify whether these offenders consistently performed the same behaviors across their series of homicides and whether it is more effective to examine individual behaviors or groupings of behaviors in order to identify behavioral consistency. This study provides the first empirically based evidence testing the use of using single behaviors as linking factors in linking homicide cases in a series, and shows that this method has inherent difficulties in accomplishing this, thus providing the first wave of empirical testing that questions current theories in the literature on serial homicide, which has suggested that signatures or specific key behaviors are important in understanding the consistency in an offender's behavior across the crimes. Recommendations for future studies on linking using signatures are suggested, including a more in-depth qualitative empirical evaluation of individual series.     

Comparing single and serial homicide offenses

Serial homicide has attracted much attention, but little empirical scientific investigation. This exploratory study reports demographic information on a large sample of serial homicide offenders (157 offenders, 608 victims), and compares a subsample of serial homicide offenses with a control group of single homicide offenses. Results show that serial homicide offenders target more women than men, and kill more strangers than family or friends. Single homicide offenders kill men and women in equal frequency, but kill family and friends more often than strangers. Serial homicide offenders kill for apparent sexual motivation more often than for any other reason, while single homicide offenders kill most often out of anger.     

Classification of Planning and Violent Behaviours in Serial Homicide: A Cross‐National Comparison Between South Africa and the US

Recent literature suggests that different ‘styles’ of homicide will most appropriately be reflected in the different types of behaviours committed by offenders during the crime. In the last few years, there has been a move to standardise classification systems of single homicides and establish their cross‐national generalisability. Literature on serial homicide to date has mostly centred on homicides occurring in the US. However, national differences due to factors such as culture, national identity, political, and socio‐economic circumstances may decrease the applicability of these models or certain aspects thereof in other countries and thus must be evaluated. The present study tested the applicability in the South African context of a recently developed US‐based serial homicide crime scene classification framework. Specifically, this study compared the thematic differentiation in planning and violent behaviours that the offenders engage in and how this differentiation compares with that in the US. The sample consisted of 25 homicides that were in total responsible for the murder of 267 victims. Results indicated that overall, the framework is useful and applicable in the South African sample, but important environmental and contextual constraints must be taken into account.

Serial homicide: an investigation of behavioural consistency

To examine if serial homicide offenders are consistent across their crimes, a model was developed empirically that could be used to distinguish between crimes that were instrumental and those that were expressive. The first known three offences in each series of 69 US serial homicides committed by 23 offenders, were examined and the instrumental and expressive themes determined. Three models were then explored that test for consistency across these themes. The most liberal model was found to classify all of the offences effectively and to reveal complete consistency across the three crimes for all offenders. The implications of these results for offender profiling and further study of serial homicide are discussed. Copyright © 2005 John Wiley & Sons, Ltd.     

South African Serial Homicide: Consistency in Victim Types and Crime Scene Actions Across Series

Key to understanding the significance of behavioural evidence for linkage purposes is in establishing how consistently an offender displays the same or similar behaviours across their series. There have however to date been very few studies aiming at identifying salient components of offending behaviour that can be used reliably for linking individual crimes as part of a single series. In addition, studies that have been conducted have all dealt with serial homicide in the Western world and have been based on small samples of cases from each country. Some of the recent literature has started to disentangle some of these salient features, notably the victim, violence levels, control, and planning. The current study focused on evaluating the consistency of these features across series, using a sample of serial homicides from South Africa consisting of 30 offenders with a total of 283 victims and 235 crime scenes. Results indicate that the level of interaction with the victim may be influential to the stability or instability of offending patterns across the series. How offenders approach planning in their offence also showed a certain degree of consistency, with patterns of violence being the least consistent across the series of all components tested.

Rational cognitive therapy with public offenders

In addressing the issue of how offenders may help themselves face the world in prison and outside, this article outlines how the principles of rational emotive therapy as outlined by Ellis and Maultsby can be simplified for use with this population in order to provide them a method for understanding and alleviating unhelpful emotional reactions. An example is provided to illustrate how a rational self-analysis model can be taught as written homework in individual or group sessions. Using the RSA model, offenders are taught to review and better understand the meanings of irrational words and how they upset themselves. Overall, our experience has been that offenders of many persuasions can be taught to be more rational and logical—an essential foundation for successful rehabilitation.

Testing Existing Classifications of Serial Murder Considering Gender: An Exploratory Analysis of Solo Female Serial Murderers

Serial murder is a genre of crime that has received a great deal of media and academic attention, yet, serial murder committed by women has only begun to garner a portion of this attention within the last 15 years. This study examines the reliability of Kelleher and Kelleher's classification rubric, the only classification system developed for female serial murderers, as well as considering Hickey's classification of serial offenders by location. Other variables associated with homicide research have also been examined to determine their roles in both these crimes and classifying offenders. The current research will demonstrate that offender motivation is not an ideal basis for the classification of female serial murderers, who tend to defy simple or singular classification within existing typologies. The other variables analysed indicate that victim–offender relationship and victim approach are important to understanding these female offenders and their crimes, as well as the possible development of more accurate classification systems.

Relationship Context,Body-Esteem,Religiosity, and Sexual Experience: Associations with Well-Being and Relationship Status

Abstract

In this study we explored why there are sometimes conflicting findings regarding the influence of past sexual experience on relationships. Consequently, we studied the effects of body-esteem and religiosity on sexual experience in two relational contexts (casual or committed relationships) and how all of these variables were associated with life satisfaction, and the likelihood that a person would be married by their early thirties. With a national sample of 4966 participants, our results indicated that sexual experiences in casual relationships had negative associations with life satisfaction and relationship status, whereas sexual experiences in committed relationships had positive associations.     

Children Who Murder: A Review

Despite considerable research on juvenile homicide, pre-adolescent homicide offenders have received less attention. This paper reviews the existing literature on preteen murderers in order to characterize the current state of research knowledge about this population, and draws on some of the work on adolescent homicide as well. The analysis of this literature considers historical context, methodological issues, previous attempts to classify youthful homicide offenders, and predictors of preteen homicidal behavior. While there is a high degree of heterogeneity within this population, several developmental similarities emerged across cases that were associated with the perpetration of homicide by preteens. A high percentage of preteen homicide offenders come from homes characterized by physical abuse, domestic violence, poor or absent parenting, and overall instability. Gun availability may have been a facilitating factor. Support for different etiologies of preteen versus adolescent homicide is weak. Recommendations for future research directions are offered.     

Recidivism among four types of homicide offenders: An exploratory analysis of 336 homicide offenders in New Jersey

Despite a great deal of information on various types of offenders, there is only limited longitudinal research on the offending patterns, typologies, and recidivism of different types of homicide perpetrators. A random sample of 336 homicide offenders who were released between the years 1990 and 2000 from the New Jersey Department of Corrections were identified and followed for a minimum of 5 years. These offenders were tracked to determine if incarcerated homicide offenders who had no criminal histories prior to their homicide conviction recidivated less, and which specific variables correlated with recidivism. As a result of our analysis, we conceptualized a new four-fold typology of homicide offenders: 1) homicide that was precipitated by a general altercation or argument, 2) homicide during the commission of a felony, 3) domestic violence-related homicide, and 4) a homicide after an accident. In conclusion, none of the 336 homicide offenders committed another murder. However, we found the highest recidivism for new violent or drug crimes occurred in the felony homicide group (slightly over one-third), followed by the altercation precipitated homicide offenders (27%), which was in sharp contrast to the domestic violence homicide offenders with less than 10% recidivism due to a new violent or drug offense.     

South African Serial Homicide: A Victim‐Focused Behavioural Typology

This current study assessed the value of the Interpersonal Model in differentiating serial homicide offences in South Africa, notably in terms of how the offender may display behavioural patterns that are indicative of them dealing with the victim as a Person, an Object, or a Vehicle. The sample consisted of 302 offences committed by 33 offenders that occurred from 1953 to 2007 in South Africa. Multidimensional scaling analysis was used to test the Interpersonal Model and results indicated that crime themes did not directly correspond to the threefold model. Instead, two crime scene types were present: Victim as Object (where the focus was on tangible gains, interaction with the victim throughout the phases of the crime was limited, and victims included men and live women) and Victim as Vehicle (where the victim might be construed as a conduit through whom the offender could realise their specific psychological needs, the interaction was extensive, and victims tended to be vulnerable). South African serial homicides did not appear to have a specific sub‐theme of Victim as Person, suggesting that the themes engaged in centred more on instrumentally focused actions but in qualitatively different ways. However, victim types were integral to the overall behavioural model. Using the Victim as Object/Vehicle dichotomy, 85.7% of the offences could be seen to engage dominantly in one of the two patterns at the crime scene. This not only supported the results of a twofold model, but having these many offenders showing a dominant crime scene type also shows that the model is an excellent representation of serial homicide offending in South Africa.

Healthcare Serial Killers as Confidence Men

Although there is adequate coverage of serial murder in the extant homicide literature, there is a lack of systematic examination of healthcare professionals who serially murder their patients. Using a sample of 58 healthcare serial killers located within North America, South America, and Europe between the years of 1970 and 2010, this study examines notable pre‐offense and post‐offense behaviours of healthcare serial killers. Patterns related to offender aetiology, victim cultivation, crime scene behaviour, and techniques of evasion were explored. The findings from this study suggest that the pre‐offense and post‐offense behaviours of healthcare serial killers can be conceptualised from the theoretical framework of confidence men or ‘con men’. The findings from this study also suggest that healthcare serial killings and offenders who perpetrate them continue to be elusive and warrant additional scholarly attention to reduce their likelihood of engaging in homicide undetected for extended time. Policy implications are also discussed. Copyright © 2013 John Wiley & Sons, Ltd.     

Pathways in the offending process of sex offenders who target marginalised victims

Prior literature shows that although marginalised populations are at a high risk of severe violence and homicide, research has focused on their offenders as if they constituted a homogeneous group. On the basis of a sample of 213 sex offenders who targeted marginalised individuals (i.e., sex trade worker, homeless individual, and severe drug user), we investigate the different pathways that these offenders take both prior to and during the commission of their crimes. Results of 2‐step cluster analysis regarding the offender's development, criminal history, crime context, and modus operandi revealed 3 distinct pathways of the offending process. The coercive pathway was characterised by the amount of violence used against the victim. The explosive pathway was defined by offenders who were in a state of rage at the time of the offence. Finally, offenders in the situational pathway committed their crimes out of opportunity and used very little violence. Differences between pathways were investigated with regard to characteristics of the index offence.     

Offender-Victim Relationships in Criminal Homicide Followed by Offender's Suicide,North Carolina, 1972–1977

ABSTRACT: An analysis of 90 cases of criminal homicide followed by suicide in North Carolina, 1972 to 1977. Homicidal victim-offender relationships were investigated in regard to age, sex, race and whether victim and offender were member of the same family, friends, acquaintances, or strangers. These results were compared with victim-offender relationships in 994 criminal homicide cases in North Carolina in which offenders did not commit suicide. Married white males over 30 years were much more involved in homicide-suicide than they were in homicide alone. In these homicide-suicide cases, the victim was usually the spouse. Except for marital status, characteristics of homicide offenders who killed themselves resembled those of suicide-only individuals much more than those of homicide-only offenders. In the homicide-suicide cases, the killing of someone in close relationship to the offender, often a wife, appeared to be part of the evolving process of suicide. This clearly has implications for intervention into marital strife and also for immediate treatment of homicide offenders who kill spouses and other family members.     

The collectors: Serial sexual offenders who preserve evidence of their crimes

In our prior research, we have encountered a distinct category of serial, sexual offenders who invest themselves in developing unique collections of artifacts that link them to their victims. This behavior is counter-intuitive as it represents irrefutable proof of their responsibility for multiple serious crimes. Nonetheless, the process of collecting these artifacts and the experience of maintaining them together, and in proximity to the offender, appear to represent a psychological experience that is central to the motivation for perpetrating the crimes. In this paper, we explore five modalities of recording used singularly or in combination by some of the most prolific and egregious sexual offenders prosecuted in the past 40 years. We use these case studies as a platform for exploring the psychological dynamics underlying this behavior, and to further alert law enforcement and forensic evaluators to the existence and significance of these unique forms of crime evidence.     

Understanding Intimate Partner Sexual Assaults: Findings from Sexual Assault Kits

ABSTRACT

In 2013, Cuyahoga County, Ohio, began DNA testing and investigating nearly 5000 previously unsubmitted sexual assault kits (SAKs) from 1993 through 2009. We examined case files from a sample of SAKs that were tested but not previously adjudicated (n = 429). More than 10% (n = 45) involved victims who reported to police that a former or current intimate partner sexually assaulted them. This article integrates the available data on the offenders, the victims, the initial investigation, and the specifics of the assaults to provide a more complete understanding of intimate partner sexual assault (IPSA). More than one-third of the IPSA offenders were serial sex offenders; that is, the offenders sexually assaulted an intimate partner and another person(s). Comparing IPSAs to all other sexual assaults, IPSAs more frequently involved bodily force, less frequently involved a weapon, and IPSA investigations were more frequently closed because (1) the victims stated they lied or the police doubted the victims and (2) the victims declined to prosecute. The most common sequencing of events was a demand for sex by the offender followed by a verbal refusal by the victim and the use of bodily force in the sexual assault. The findings, however, indicate a great deal of variation in the sequencing of events surrounding the sexual assault, with over 25% involving no physical confrontation before or after the sexual assault and no demands for sex. Unsubmitted SAK data provide a unique window into understanding the understudied and underreported issue of IPSA.
