Sexual murderers of children: developmental, precrime, crime, and postcrime factors

The amount of empirical research on men who commit sexual murders is scarce, and no distinction has been made between those who have victimized adults and those who have victimized children. Therefore, to better understand specifically sexual murderers of children (n = 11), comparisons were performed with a group of sexual murderers of adult women (n = 66) on developmental, precrime, crime, and postcrime factors. It appears that sexual murderers of children are more often victims of sexual abuse during childhood and present more often deviant sexual fantasies as compared to sexual murderers of women. The results show also that sexual murderers of children more often use pornography prior to crime, have contact with the victim prior to crime, and commit a crime more often characterized by premeditation, strangulation, the hiding of the body, and its dismemberment than the sexual murderers of women.     

The influence of brain abnormalities on psychosocial development, criminal history and paraphilias in sexual murderers

The aim of this study was to investigate the number and type of brain abnormalities and their influence on psychosocial development, criminal history and paraphilias in sexual murderers. We analyzed psychiatric court reports of 166 sexual murderers and compared a group with notable signs of brain abnormalities (N = 50) with those without any signs (N = 116). Sexual murderers with brain abnormalities suffered more from early behavior problems. They were less likely to cohabitate with the victim at the time of the homicide and had more victims at the age of six years or younger. Psychiatric diagnoses revealed a higher total number of paraphilias: Transvestic fetishism and paraphilias not otherwise specified were more frequent in offenders with brain abnormalities. A binary logistic regression identified five predictors that accounted for 46.8% of the variance explaining the presence of brain abnormalities. Our results suggest the importance of a comprehensive neurological and psychological examination of this special offender group.     

The Motivation Behind Serial Sexual Homicide: Is It Sex,Power, and Control,or Anger?*

Controversy exists in the literature and society regarding what motivates serial sexual killers to commit their crimes. Hypotheses range from the seeking of sexual gratification to the achievement of power and control to the expression of anger. The authors provide theoretical, empirical, evolutionary, and physiological support for the argument that serial sexual murderers above all commit their crimes in pursuit of sadistic pleasure. The seeking of power and control over victims is believed to serve the two secondary purposes of heightening sexual arousal and ensuring victim presence for the crime. Anger is not considered a key component of these offenders' motivation due to its inhibitory physiological effect on sexual functioning. On the contrary, criminal investigations into serial sexual killings consistently reveal erotically charged crimes, with sexual motivation expressed either overtly or symbolically. Although anger may be correlated with serial sexual homicide offenders, as it is with criminal offenders in general, it is not causative. The authors further believe serial sexual murderers should be considered sex offenders. A significant proportion of them appear to have paraphilic disorders within the spectrum of sexual sadism. "sexual sadism, homicidal type" is proposed as a diagnostic subtype of sexual sadism applicable to many of these offenders, and a suggested modification of DSM criteria is presented.     

Murderer vs investigator: factors influencing the resolution of sexual homicide cases

ABSTRACT

The objective of this study was to identify the factors associated with the duration of criminal investigations and determine whether these factors influence the seriality of sexual murderers. To this end, data on the investigation of 62 sexual homicides (homicides committed by a serial sexual murderer = 24; homicides committed by a nonserial sexual murderer = 38), were analyzed. Organized behaviors, typical of serial sexual murderers, were not all associated with a longer criminal investigation. However, it was possible to develop a model of the duration of investigations, and predict the seriality of sexual murderers, by taking into account the decisions of murderers and investigators.     

Journey to murder: examining the correlates of criminal mobility in sexual homicide

Although the empirical research on the journey to crime seems to indicate that most crimes are committed close to home, only a few studies have specifically examined the journey to crime in cases of sexual homicide. Using a sample of 214 sexual homicide cases, the current study investigates, using logistic regression, offenders who travel during the crime to those offenders who commit their crime, all at the same location. Current findings suggest that sexual murderers who engage in intra-crime travel tend to use a vehicle in the commission of their offence, target adult victims who are involved in the sex trade and move the body post murder.     

Toward a quantitative typology of burglars: a latent profile analysis of career offenders

Burglary is a serious, costly, and prevalent crime but prior typologies of burglars are mostly speculative and based on qualitative data. Using a sample of 456 adult career criminals, the current study used latent profile analysis to construct a methodologically rigorous quantitative typology. Four classes of burglars emerged: young versatile, vagrant, drug-oriented, and sexual predators. All groups demonstrated significant involvement in varied forms of crime, but the sexual predator group was the most violent and had the most serious criminal careers. Connections to the criminal career literature are offered and suggestions for further empirical study of offender typologies are discussed.     

Performance intelligence,sexual offending and psychopathy

Abstract

Previous studies have suggested that offenders have lowered verbal intelligence compared to their performance intelligence. This phenomenon has been linked traditionally to childhood risk factors (e.g. deficient education, abuse and neglect). Substantial discrepancies between performance intelligence quotients (PIQ) and verbal intelligence quotients (VIQ), however, might also point to neurobiological impairments which may be associated with specific types of criminal behaviour. From the files of 133 male hospitalized offenders, PIQ, VIQ, full scale IQ (FSIQ) scores and Psychopathy Checklist–Revised (PCL-R) scores were derived, along with information about their criminal histories. PIQ over VIQ discrepancies were most pronounced in sexual offenders, particularly in those who had committed sexual crimes against adult victims. Furthermore, PIQ as well as PIQ higher than VIQ discrepancies correlated modestly, but significantly, with PCL-R scores. The results suggest that lower verbal compared to visual and spatial abilities may be connected specifically to egocentric and narcissistic personality traits which, in turn, may be involved in raising the risk of sexual offending.     

Gender difference or indifference? Detective decision making in sexual assault cases

Prior research examining sexual assault case decision making has failed to account for the demographic characteristics of the criminal justice practitioners charged with making case decisions. Inclusion of such information is important because it provides researchers with a greater understanding of how criminal justice practitioners' own gender, race, age, and past experiences affect their judgments. This study seeks to examine whether gender differences exist in detectives' arrest decisions in sexual assault cases. Victim, suspect, incident, and detective characteristics are collected from police case and investigatory files on 328 criminal sexual assault cases involving adult female victims reported to a large Midwestern police department in 2003. Logistic regression is used to determine whether detective gender predicted the odds of arrest after controlling for incident, victim, and suspect characteristics. It is hypothesized that cases involving female detectives would be more likely to result in arrest after controlling for other incident, victim, and suspect characteristics. However, contrary to expectations, female detectives are significantly less likely than male detectives to arrest suspects in sexual assault cases even after controlling for the influence of other factors shown to predict arrest. The findings support prior research that suggests female practitioners may not necessarily be more sensitive toward female victims despite previous assumptions that this would hold true. The findings suggest that efforts to hire female police officers for the purposes of dealing with female-related victimization may ultimately undermine efforts to improve victim experiences with the criminal justice system. They further suggest that both researchers and police administrators need to rethink the best ways to serve female victims beyond hiring mandates.     

Profiles in the offending process of nonserial sexual murderers

The aim of this study was to investigate specific pathways in the offending processes of nonserial sexual murderers and to examine possible relationships with different precrime, per-crime, and postcrime factors. Included in this study were 36 offenders who have committed at least one sexual murder against a female victim and they were classified using cluster analysis. Participants using the sadistic pathway planned their offenses and used physical restraints during the offenses. Furthermore, they mutilated and humiliated their victims. Finally, they hid the bodies of the victims. Participants using the anger pathway had not premeditated the homicide. Mutilation, humiliation, and physical restraints were less predominant with these participants than with those using the sadistic pathway. Moreover, these offenders were more likely to leave the bodies at the crime scenes after the killings occurred. These two profiles are compared with empirical studies addressing sexual homicide.     

Procedural Justice and Psychological Effects of Criminal Proceedings: The Moderating Effect of Offense Type

It is well-established that victims of crime have numerous preferences when encountering the criminal justice system. Often, research examines these preferences in terms of procedural justice, asserting that elements such as voice, respect, and fair treatment may lead to greater satisfaction and more positive experiences. Positive experiences also entail preventing secondary victimization by the legal system. Much of the research surrounding this topic, however, discusses victims of crime as a single entity. The current research examines if differences among crime victims, namely whether they suffered sexual or non-sexual victimizations, influence their legal preferences. Victims of sexual assault have undergone particularly traumatic and stigmatizing experiences that may warrant a greater need for expression and understanding of their harm. It is hypothesized that for victims of sexual assault, there will be a stronger association between procedural justice and negative psychological effects of criminal proceedings. Therefore, type of offense is examined as a moderator variable of this relationship. Hierarchical regression analysis indicated that there is in fact an interaction effect for procedural justice and psychological effects, suggesting that these preferences are more desired by victims of sexual assault.     

The pathology and medicolegal aspects of sexual activity

The pathology of injury and its complications related to sexual activities has changed remarkably when compared with that of the past, which usually involved assaults or murders of female victims of varying ages, with moderate to serve beatings that may have accidentally resulted in the victim's death. Serial murderers, serial rapists, and molesters of both boys and girls have become much more prevalent in the last two decades in the United States. Unorthodox sexual behavior, such as "fisting," has increased in frequency, as has sexual violence related to cults, such as satanism. All of these present many challenges to medicolegal investigators. This report describes general and specific pathological sexual activities and injuries, some characteristics and methods of the perpetrators, and some specific cases as examples.     

Rosemary west: Motives and meanings

Abstract

This article originally appeared in Trouble and Strife (Winter 1996/97, pp 44-52) and is reproduced, by kind permission of the original publishers, as Deborah Cameron's thought-provoking analysis of the Rosemary West case is felt to deserve a wider audience.

In the article, Deborah Cameron reports that feminists were mostly silent about the Rosemary West case in spite of having an analysis of sex crime, because female perpetrators of sexual murder seemingly did not fit that analysis. She argues, however, that female sexual murderers can be understood within a feminist framework. Identifying Rosemary West as one of only a handful of female sexual murderers, Cameron theorises that Rosemary and Fred West, like other sexual murderers, were constructing a form of identity based on sexual transgression and existential transcendence, perhaps as a strategy for dealing with their own history of abuse. What Cameron also provides us with is an explanation for why sexual murderers are overwhelmingly male, an analysis based on an understanding of the context of patriarchy.     

Juvenile Sexual Murderers: Examination and Classification of the Crime-Commission Process

This study aims to empirically explore the crime-commission process of juvenile sexual homicide offenders (SHOs). First, a comparison between the crime-commission process of juvenile and adult SHOs is undertaken, while as a second step, this study also provides an empirical classification specific to juvenile SHOs. The sample used in this study consists of 55 juvenile SHOs and 281 adult SHOs. A sequential binomial regression was used to compare at the multivariate level the two groups of offenders, while a latent class analysis was used to examine the relationships between each step of the crime-commission process of juvenile SHOs. Our findings suggest that the crime-commission process of juvenile SHOs present differences when compared with adult SHOs. Moreover, we identified four different patterns in juvenile sexual homicide: explosive opportunistic, sadistic, overcontrolled anger, and predator. Theoretical and practical implications in terms of criminal investigations as well as offenders’ management and treatment are discussed.     

Sexual and violent recidivism by offender type and actuarial risk: reoffending rates for rapists,child molesters and mixed-victim offenders

Abstract

The current study examines sexual and violent reoffence rates for a sample of 2474 sexual offenders over an average of 15 years following release from prison. Reoffence rates are reported as a function of the offenders' victim type and level of risk as assessed by the Automated Sexual Recidivism Scale, a computer scored measure of relevant historical risk factors. Observed sexual recidivism rates for offenders with child victims, adult victims, and mixed victims were quite similar. Results indicate that offenders with exclusively female child victims not only showed a lower rate of sexual reoffending, but that the reoffence rates were relatively low across all levels of actuarial risk. In contrast, those with male child victims and adult victims showed a pronounced escalation of reoffence rates as actuarial risk increased. Results also indicated that adult victim offenders are less consistent in the victim type of their reoffences, with 37% sexually reoffending against child victims. Finally, combined rates of sexual and violent reoffending were particularly high for those with adult victim sexual offence histories. Risk assessment and public policy implications are discussed.     

Forms of Social Support That Moderate PTSD in Childhood Sexual Abuse Survivors

Although social support has been found to attenuate psychological symptoms in victims of sexual abuse, literature does not identify the specific forms of social support that mitigate maladjustment following a sexual abuse experience. This study sought to distinguish the specific types of perceived social support that buffer the development of post-traumatic stress disorder (PTSD) in victims of childhood sexual abuse (CSA). One hundred and seventy-two adult females reporting CSA were administered the Interpersonal Support Evaluation List (ISEL) and the Impact of Events Scale (IES). The ISEL measures the perceived availability of 4 support types. The IES measures core PTSD symptoms of intrusion and avoidance. Regression analysis indicated that social support significantly buffered PTSD development. The best model was one which contained self-esteem and appraisal support. Tangible and belonging support added little to prediction. Further, self-esteem support was identified as the most important variable in preventing PTSD development.     

刑事被害人当事人化的反思与制度重构

刑事被害人当事人化的实质是犯罪损害追诉方式的公私合一,该制度设计混淆了公益和私益两种不同性质的诉讼,导致两种权益保护相互冲突进而对刑事司法结果公正造成负面影响。公私分离是刑事被害人去当事人化的当然制度选择,其立法对策主要包括在刑事立法中确立被害人为特殊诉讼参与人、废除被害人在刑事审判中就定罪量刑发表意见的权利、废止被害人刑事自诉权和切断其引起刑事二审、再审的程序路径。同时需要完善相关配套举措,如允许被害人对其物质和精神损害单独提起民事诉讼、完善精神损害赔偿制度、建立刑事被害人国家补偿制度等。     

Offending histories and offending behaviour: A Ten year follow-up of sex offenders tried by Sheriff and District Courts in Grampian,Scotland

From criminal complaint records all incidents of sexual misbehaviour resulting in charges in three North East Scotland courts during 1981 and 1982 were traced. Of the 80 alleged offenders, 75 were followed up for 10 years using current criminal records.

Offending behaviour ranged from obscene telephone calls to rape. Half the offenders made no physical contact with their victims. These “hands-off” offenders were compared with “hands-on” offenders and were found to show a higher prevalence of sexual convictions both before the index offence and in the follow-up period. Those offenders who removed their victims clothes or had sexual intercourse with their victims were found to have the lowest prevalence of sexual reoffending. Degree of intrusiveness was inversely related to sexual recidivism in this sample and there was no evidence of progression over time to more intrusive offending.
