An Exploration of Rapists' Motivations as Illustrated by Their Crime Scene Actions: Is the Gender of the Victim an Influential Factor?

An aim of this paper was to examine if the rapist's motivations of anger and power as inferred from rape crime scene behaviours differentiates between rape victim genders. In addition, it was sought to analyse the resistance strategies employed by rape victims to investigate whether gender influences victim–offender behavioural interactions. A sample of 24 female and 12 male rape victims aged from 13 to 39 years were analysed. The data were extracted from the US National Crime Survey, which contained 12 reported cases of male rape. It was hypothesised that the theme of power would be evident from the rapists' behaviour as illustrated by the crime scene actions and victim–offender interaction. Smallest Space Analysis, a multi‐dimensional scaling technique, was employed to identify the themes present in the perpetration of rape. The crime scene actions illustrated several distinctions relating to the theme of power present in the offender's motives irrespective of the victim's gender. An additional finding was that victim resistance strategies differentiated between male and female rape victims. Copyright © 2014 John Wiley & Sons, Ltd.     

When is profiling possible? Offense planning and aggression as moderators in predicting offender age from victim age in stranger rape

Debate continues with regard to the possibility of inferring an offender's characteristic features from crime scene details (the process of so-called "offender profiling"). We argue that psychology generally has benefited from appreciating context in predicting behavior. In the same way, profiling would benefit from an appreciation of context in predicting characteristics. This "reverse" process is contingent on various "if...then" relationships. As one example, this paper demonstrates how profiling offender age from victim age is contingent on (i) the level of planning and (ii) the level of aggression displayed during the offense. Eighty-five stranger rape case records formed the data set. Moderated regression analysis revealed that victim age is a significant predictor of offender age only in cases where the offender has (i) shown evidence of planning the attack and/or (ii) acts in a gratuitously aggressive manner. The theoretical bases for these findings may lie in the extent to which offenders disparately plan and target victims and how extreme aggressiveness in stranger rapes may relate to a near-peer proxy for an offender's anger. The implications of the results for the processes and methods involved in offender profiling suggest that certain crime scene factors can have differential moderating effects on predictive outcomes.     

Investigating the nature of expressiveness in stranger,acquaintance and intrafamilial homicides

This study explores the role of the victim–offender relationship in the dynamics of homicide, by examining the crime scene behaviour of 25 intrafamilial, 30 acquaintance and 27 stranger homicide offenders (n = 82). Six crime scene variables were examined: ‘Weapon from the scene’, ‘Excessive wounding’, ‘Facial trauma’, ‘Multiple wounds to a single area’, ‘Post‐mortem activity’ and ‘Manual violence’. The first objective was to identify whether these variables could be combined to form a partially ordered scale of expressiveness. The second was to examine whether the nature of this expressive crime scene varied according to the victim and offender relationship. It was hypothesised that the intrafamilial homicides would be characterised by a more expressive crime scene. This was examined by Partial Order Scalogram Analysis which supported the hypothesised link between the level of expressed emotion evident in the crime scene and the nature of the victim–offender relationship. Further analysis on the individual variables revealed that the best single predictor of the relationship between victim and offender was the presence of multiple wounding. These findings are discussed both as contributing to a theoretical understanding of the emotional salience of crime scene actions when killing a family member, and in practical terms in relation to the significance of these variables for both police investigations and clinical interventions with homicide perpetrators.

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.

Offending Patterns of Serial Sex Offenders: Escalation,De‐escalation,and Consistency of Sexually Intrusive and Violent Behaviours

A series of stranger sexual assaults poses considerable obstacles for law enforcement officials. One such preoccupation is concerned with whether or not the offender will escalate in the severity of his behaviours with subsequent victims. The current study uses transition matrices to address whether or not the offending patterns of 72 serial stranger sex offenders change from one victim to the next as it pertains to their sexual acts and level of physical force used during the crime. Findings indicate that stability, specifically the offender's intrusive sexual acts and use of physical force, and versatility are present in this sample's offending patterns. To explain changes in offending patterns between victims, multinomial regression analyses indicate that situational factors and modus operandi strategies are important considerations. Implications for investigations are discussed. Copyright © 2013 John Wiley & Sons, Ltd.     

'NEVER TWICE WITHOUT THRICE' AN OUTLINE FOR THE UNDERSTANDING OF TRAUMATIC NEUROSIS

Following the review of Freud's work on trauma (1916-17, 1920, 1926, 1933, 1939), this article proposes to view the traumatic scene as a screen which acts as an active process in the case of many victims who, like Mrs D, break down a few days after being assaulted. After a first attempt at denial, the ego is submerged with repressed content. Repetition is seen as a means of abreacting the trauma by seeking to bind the enormous quantity of excitations that cannot find discharge. Repetition, because of its compulsive quality, fails. The victim remains in a state of helplessness against which she resorts to denial, splitting and projection (Freud, 1920, 1926). This strategy is seen, however, as maintaining the victim in a state of helplessness. Thus, I suggest that, overwhelmed, the ego finally resorts to a multi-levelled system of defence. On a first level, fixation to the trauma, like in screen-memories, gives way to a first displacement. On a second level, the adoption of an identity built upon being a victim contributes to the strength of this displacement. On a third level, identification with the aggressor consolidates this defensive strategy by giving meaning to the hostility awakened by the sexual assault.     

Victim Gender,Number of Perpetrators,and Interpersonal Interaction in Stranger Rape: An Analysis of Direct and Moderator Effects

This study examined the direct and moderator effects of number of perpetrators and gender of victim on interpersonal behaviour in stranger rape. Crime scene behaviours representative of hostility, involvement, control, and offender penetration in rape were examined for 496 UK, police‐recorded cases of stranger rape. Cases were grouped according to victim gender (male or female) and number of perpetrators (lone or multiple). This resulted in four groups (lone female, lone male, multiple female, and multiple male) with 124 cases in each. Binary logistic regression and one‐way analysis of variance were used to investigate the relationships between the two predictor variables and 11 criterion variables. Significant direct effects of number of perpetrators were found whereby multiple perpetrator offences were more likely to involve violence and less likely to involve involvement interactions than lone perpetrator offences. Significant direct effects of victim gender were also found whereby male victims were more likely than female victims to experience hostile interactions and be threatened with a weapon and were less likely to experience offender penetration and involvement interactions. Significant crossover interactions were also found for four hostility variables. The utility of the findings are discussed in relation to crime prevention, victim support, and offender intervention.

Examining the Role of Similarity Coefficients and the Value of Behavioural Themes in Attempts to Link Serial Arson Offences

When relying on crime scene behaviours to link serial crimes, linking accuracy may be influenced by the measure used to assess across‐crime similarity and the types of behaviours included in the analysis. To examine these issues, the present study compared the level of linking accuracy achieved by using the simple matching index (S) to that of the commonly used Jaccard's coefficient (J) across themes of arson behaviour. The data consisted of 42 crime scene behaviours, separated into three behavioural themes, which were exhibited by 37 offenders across 114 solved arsons. The results of logistic regression and receiver operating characteristic analysis indicate that, with the exception of one theme where S was more effective than J at discriminating between linked and unlinked crimes, no significant differences emerged between the two similarity measures. In addition, our results suggest that thematically unrelated behaviours can be used to link crimes with the same degree of accuracy as thematically related behaviours, potentially calling into the question the importance of theme‐based approaches to behavioural linkage analysis.

Public Perceptions of Sexual Harassment: An Empirical Analysis in Israel from Consensus and Feminist Theoretical Perspectives

Sexual harassment (SH) includes men as harassers and women as victims. It is defined in many Western countries as a criminal offense. However, the social response to SH may be characterized by clear leniency toward harassers. The present study investigated the roots of such response. Respondents from a large, representative, random, Israeli sample (630) were asked to evaluate hypothetical short crime scenarios, constructed by the factorial-survey approach, representing cases of sexual harassment and other offenses. The study hypothesized that respondents’ perceptions of SH scenarios will be affected significantly by their gender-role attitudes to women. The findings indicate that such criminal acts are perceived as serious by the whole public, challenging the consensual basis of the lenient approach to harassers.     

Enhancing the salience of free speech rights increases differential perceived free speech protections for criminal acts against Black versus White targets

Hate crime charges offer enhanced sentences for prejudice‐motivated acts in recognition of the injury that extends beyond the victim to other members of the targeted group. The present study builds upon and extends previous work illuminating how anti‐Black prejudice influences application of free speech protections to justify criminal acts against Black (vs. White) targets, which subsequently reduces support for hate crime charges for the act by investigating the potential effects of environmental cues that increase the salience of free speech rights. The present work tested the main and interactive effects of act target (Black vs. White), anti‐Black prejudice, and the salience of freedom of speech on perceived free speech protections for a prejudice‐motivated criminal act and the consequent influence on support for hate crime charges. Replicating previous findings, greater anti‐Black prejudice predicted more perceived free speech protections for Black‐targeted acts, which predicted less support for hate crime charges. Low‐bias participants viewed Black‐ versus White‐targeted acts as less protected by free speech rights and more deserving of hate crime charges; high‐bias participants viewed the two acts similarly. Making the right to free speech (compared to protections from search and seizure) salient amplified differential perceptions of free speech protections based on prejudice and target group, which predicted support for hate crime charges. This work holds implications for justification processes and highlights the importance of studying culture‐specific values.     

Differentiating stranger murders: profiling offender characteristics from behavioral styles.

The literature on "offender profiling" suggests that different "styles" of homicide will reflect differences in the background characteristics of the offender. To test this suggestion, hypotheses were drawn from studies of aggression to propose that murder crime scenes would reveal stylistic distinctions in the role of the aggression in the offense. It was further hypothesized that these distinctions would be clearest for those crime scene indicators that reflect the instrument (cognitive) actions that shape the offense rather than the more expressive (impulsive and emotional) components. Hypotheses about associated offender characteristics were also deduced on the assumption that the murder scene theme revealed the killers' typical styles of interpersonal transaction. To test these hypotheses MDS analyses were carried out on the crime scene and offender characteristics derived from 82 single offender, single victim stranger homicides. A multivariate structure resulted, including all three hypothesized styles, allowing 65% of the cases to be assigned to unique styles and a further 36% to be assigned to appropriate hybrids. Offender characteristics related in the anticipated way to the different crime scene styles, providing a basis for law enforcement inferences about offenders in stranger murders.     

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.

Placing the Blame for crime in press reports

This study examined the attributions of responsibility contained in factual accounts of crime in a number of Canadian daily newspapers. The focus was upon the relative amount of coverage accorded crime suspects and victims, as well as upon the presence or absence of references to the victim's contribution to the offense. Also, examined were the effects of the type of crime involved and the gender of the parties to an offense upon offender/victim coverage and references to victim contribution.

As expected, offenders tended to receive greater coverage than victims. The coverage of the offender, relative to the victim, tended to be greatest when the offender was a male and a property, rather than violent crime was involved. The victim's gender did not exercise an effect on offender/victim coverage. In about one‐quarter of the articles, a mention was made of the victim's contribution to the offense. Such references to the victim's role were more likely to be found where the offender was a female, the victim a male and where the offense was violent in nature. These findings about the media portrayals of the respective roles in crime of offenders and victims, as well as the effects of the type of crime and gender on these roles, conformed, in large part, to what is known about the actual dynamics of criminal behavior.     

From marine ecology to crime analysis: Improving the detection of serial sexual offences using a taxonomic similarity measure

Jaccard has been the choice similarity metric in ecology and forensic psychology for comparison of sites or offences, by species or behaviour. This paper applies a more powerful hierarchical measure—taxonomic similarity (Δ_s), recently developed in marine ecology—to the task of behaviourally linking serial crime. Forensic case linkage attempts to identify behaviourally similar offences committed by the same unknown perpetrator (called linked offences). Δ_s considers progressively higher‐level taxa, such that two sites show some similarity even without shared species. We apply this index by analysing 55 specific offence behaviours classified hierarchically. The behaviours are taken from 16 sexual offences by seven juveniles where each offender committed two or more offences. We demonstrate that both Jaccard and Δ_s show linked offences to be significantly more similar than unlinked offences. With up to 20% of the specific behaviours removed in simulations, Δ_s is equally or more effective at distinguishing linked offences than where Jaccard uses a full data set. Moreover, Δ_s retains significant difference between linked and unlinked pairs, with up to 50% of the specific behaviours removed. As police decision‐making often depends upon incomplete data, Δ_s has clear advantages and its application may extend to other crime types. Copyright © 2007 John Wiley & Sons, Ltd.     

Classifying homicide offenders and predicting their characteristics from crime scene behavior

A theoretical distinction between instrumental and expressive aggression was used in analyzing offender characteristics and their associations with crime scene actions in Finnish homicides. Twenty-one variables reflecting the offenders' criminal activity, previous relationships with intimates and victims, and general social and psychological adjustment were derived from files of single-offender/single-victim homicides occurring between 1980 and 1994 (n = 502). Additionally, three variables describing post-offense actions and police interview behavior were included. A multidimensional scaling procedure was used to investigate the interrelationships between the variables. A distinction between expressive and instrumental characteristics was observable in the empirical structure, which was divided into three subthemes of Instrumental, Expressive: Blood, and Expressive: Intimate. Associations between the characteristics with five previously identified subthemes of crime scene actions were computed. In addition, the subthemes of crime scene actions were related to post-offense actions and police interview behavior, with Expressive themes being associated with less denial as well as a greater likelihood of surrendering and confession. The practical usefulness for police investigations and theoretical implications of the results are discussed.     

Profiling Korean sex crimes: Offender characteristics and crime scene actions

The present study aimed to examine the demographic information of sex offenders in South Korea and explore whether a U.K. thematic model of criminal behaviour could be replicated in the Korean context. The 27 variables of crime scene actions derived from 50 Korean sexual offences through a content analysis were analysed with smallest space analysis. Chi‐square was also administered to explore the differences in offender characteristics among behavioural themes. Consequently, three separate action themes, hostility–involvement, theft, and control, were revealed. Next, each case was assigned to one of the dominant or hybrid themes, with 84% of the total cases being classified to the dominant themes. Moreover, there were significant differences in four offender characteristics between the themes: “previous conviction of robbery,” “previous conviction of sexual crime,” “knowing the victim,” and “vehicle use.” These outcomes have implications for the development of the Korean profiling system.     

Sex offenders of the elderly: Classification by motive,typology, and predictors of severity of crime

A sample of 77 convicted sex offenders of elderly victims was classified by severity of and motivation for the crime. The opportunistic and non-sadistic rapists committed the lowest level crimes of no penetration. Offenders classified as pervasive anger and vindictive had the highest severity of crime scores and committed the full range of crimes from no penetration to multiple rapes and murders. Although the sample and power were small for this study, the predicting factors by severity of crime were expressive aggression, mood state — anger, victim restrained, and offense planning. Continued study on gerontophilia is necessary to discern if this behavior constitutes a paraphilia.     

Instrumental and expressive violence in Belgian homicide perpetrators

The present study aimed to examine offender types in a sample of Belgian single‐perpetrator/single‐victim homicide cases. First, it was investigated if the distinction between instrumental and expressive aggression could be documented in crime scene and offender background characteristics. Second, the instrumental and expressive themes from the first analysis were examined in relation to the motives the perpetrators themselves provided for their offence. A sample of 97 solved homicide cases was analysed using the non‐metric multidimensional scaling procedure Proxscal. The results revealed that 62% of the homicide crime scenes and 67% of the offender backgrounds could be classified as either expressive or instrumental. The self‐reported motives did not correspond with the themes according to the Proxscal analysis. Copyright © 2010 John Wiley & Sons, Ltd.     

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.
