ABSTRACTThe 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. 相似文献

Criminological research has shown the relevance of examining offender–victim interaction and related factors to understand crime event outcomes. In sexual offenses against children, an obvious lack of knowledge exists regarding this issue. From a criminological perspective, we seek to improve our understanding of the offender–victim interaction in sexual offenses against children and, in particular, what factors might increase the risk of a more intrusive offense. We argue that modus operandi strategies play a central role in crime event outcomes and examine this hypothesis with data obtained from a semistructured interview conducted with offenders. As expected, modus operandi was found to have a strong effect on crime event outcomes, especially victim participation during sexual episodes. Victim effects also emerged from the analyses. Specifically, a strong interaction effect between age and gender of the victim was found for victim participation, which suggests that as the victim gets older, offenders are more likely to make their victim participate in sexual episodes when abusing a male victim but are less likely to do so when abusing a female victim. 相似文献

Deception is often associated with economic gain and white‐collar crime. But studying deception highlights the need for criminologists and practitioners to move beyond legal definitions and conviction rates when attempting to achieve depth in understanding criminality, its motivations and possible specialisms. Further, to explore the complexity of deception requires recognition of the range of skills inherent in this modus operandi, which is better recognised as a potentially‐criminal tool found in much criminal behaviour. Theories that attempt to explain specialisation need to move on from a focus on crimes committed and give appropriate attention to skills employed. 相似文献

Homicide rate in Lithuania between 2004 and 2013 decreased and reached an average of 6.7 per 100,000 people in 2013. The data regarding forensic autopsies of intentional homicide victims were obtained from the State Forensic Medicine Service. Spearman's correlation test was used to assess trends in the homicide rates. A significant correlation was observed between homicide distribution and the following variables: Lithuania's gross domestic product (r = ?0.85, p = 0.003), the number of alcohol intoxication cases of victims (r = 0.97, p < 0.05). After regression model adjustments, these variables remained significantly associated with the homicide distribution (p < 0.05). 73% of victims were men, with a mean age of 45.5 ± 15. Alcohol intoxication was present in 58% of victims. 66% of homicides were carried out indoors, 57% in urban area. The presented findings help decide which prevention programs may be the most effective in homicide rate reduction. 相似文献

ABSTRACT This study explores the role and function of homicidal and sexual violence in cases of stranger sexual homicide. The aim was to determine whether the instrumental/expressive hypothesis of physical violence and the overt/covert hypothesis of sexual violence applies to this crime. The method involved an analysis of the crime scene actions of 81 British stranger sexual killers using multidimensional scaling. Results suggest the instrumental/expressive hypothesis of physical violence and the overt/covert hypothesis of sexual violence does apply to stranger sexual homicide but they manifest as instrumental/overt and expressive/covert superordinate themes comprising four sub-themes reflecting rape, impersonal sexual assault, overkill and control. Although these superordinate themes can explain some stranger sexual homicides, a key hypothesis of this study is that the four sub-themes can also combine into different superordinate themes, knowledge of which can aid our understanding of this serious and deviant form of interpersonal violence. 相似文献

The issue of false allegations is arguably the most controversial topic in the area of sexual violence. Portrayals of women who make false allegations are largely negative and leave little room for a comprehensive understanding of the complex motivations behind false complaints of sexual assault. The current study uses detailed qualitative data on 55 sexual assault cases that were reported to the Los Angeles Police Department in 2008 and that were subsequently unfounded. Our study focuses on identifying the factors that motivated complainants to file false allegations. Results reveal that motivations for false allegations fall into five overlapping categories: avoiding trouble/providing an alibi, anger or revenge, attention seeking, mental illness, and guilt/remorse. In addition, our findings more obviously suggest that motivations for filing false reports are varied and complex, often resulting from a need to alleviate social and personal distress. Given that we centered our study on motivations, this research is more comprehensive than prior examinations of motivations that have tackled numerous facets of false sexual assault reports. 相似文献

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. 相似文献

ABSTRACTThere is virtually no literature on child sexual abuse committed by “powerful perpetrators”, who, use position, reputation, wealth and/or power, to become influential members of their organisation. Seventeen cases relating to youth serving organisations were identified using a comprehensive search of databases covering case reviews from England, Australia and the US. A Quantitative Content Analysis was used to analyse the sample with a focus on identifying offenders’ “modus operandi”. Findings revealed a number of critical differences between powerful perpetrators and other child sexual offenders described in the literature. Findings are discussed in relation to their implications for creating safer youth serving organisations. In particular, focusing on educating YSOs to recognise and address risks posed by powerful perpetrators; expanding organisational safety policies and practices and taking steps to develop a strong, positive organisational safety culture are commended as key approaches. 相似文献

美国学者帕卡的犯罪控制模式与正当程序模式对我国的理论研究和立法实践都产生了深远的影响。但帕卡的学说还是有不足之处 :忽视了被害人的存在 ,也没有意识到对犯罪除了运用国家的刑罚权外 ,还有大量的私力救济以及官方的非正式惩罚与预防行为 ;在诉讼模式与具体制度的设计上 ,犯罪控制模式与正当程序模式学说过于强调了二者之间的对抗 ,而没有注意其相互统一和兼容之处。帕卡学说对我国的启示体现在 :学界过于强调了职权主义与当事人主义之间的差异 ,对它们在侦查制度上共同之处的研究失之准确 ;刑事诉讼法的再修改应该以职权主义模式为主 ,适当借鉴英美当事人主义中的合理因素 ;对犯罪嫌疑人、被告人与被害人的利益应该同等尊重 ,保障被害人参与诉讼过程并影响判决结果的权利 相似文献

Research on the nature of bias homicide has experienced increased interest in the academic literature. To date, few studies have compared the similarities and differences between anti-race/ethnicity bias homicides and average American homicides. Consequently, we know little about how the offender, victim, and situational characteristics compare across these two homicide types. Drawing from doing difference theory of bias crime, the aim of this study is to comparatively analyze the attributes of anti-race/ethnicity homicides to average homicides between 1990 and 2014. Anti-race/ethnicity homicide data is extracted from the U.S. Extremist Crime Database and paired with average homicides from the Federal Bureau of Investigation’s 2000 Supplementary Homicide Reports. The results of this study suggest that the characteristics of anti-race/ethnicity homicides are both similar and different from average homicides. Implications for bias crime theory, research, and policy are discussed. 相似文献

The frequent absence of a documented history of sexual assault/rape in the prior research on serial sexual murderers is curious. In order to address several methodological problems in prior research, a closed-case archival review of a nonrandom national sample of 53 serial sexual homicide cases was conducted which identified 14 offenders with a history of sexual assault/rape for an overall prevalence rate of 26.4%. Of the 14 offenders with a prior known history of sexual assault/rape, 11 (78.6%) sexually penetrated at least one of their homicide victims at the crime scene. Implications for investigation of serial sexual homicide as well as for further understanding of this exceptionally rare crime are presented. 相似文献

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. 相似文献

Recent research has expanded our understanding of sexual homicide offenders (SHOs). However, little exists beyond case reports for older SHOs. We characterized male SHOs ≥ 55 years, comparing them to typical adult male SHOs who are in their 20s. Analysis of 37 years (1976–2012) of US Supplementary Homicide Reports data provided a large SHO sample (N = 3453). Three case reports provide clinical context for the diverse nature and patterns of older SHOs. Only 32 older male SHOs and no older female SHOs were identified. Murders by older SHOs accounted for only 0.5% of US sexual homicides. Unlike typical SHOs that generally target young adult females, over two‐thirds of older SHO victims were ≥40 years, and one‐third were ≥55 years. Sexual homicides by older SHOs, like sexual homicide in general, decreased over the study period. These crimes, while exceedingly rare, do occur, warranting special consideration. 相似文献

ABSTRACTThis 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. 相似文献

This paper examines the utility of previous attempts to subcategorize child molesters. We argue that research based on these categorizations has resulted in confusion due to differences across studies concerning which offenders belong in each group. For example, there are no agreed-upon guidelines for identifying a child molester as an incest offender or as a ‘stranger’ offender. We examine research findings associated with previous attempts to subcategorize child molesters as well as the literature on modus operandi. From this, we conclude that current attempts to subcategorize child molesters are flawed. We propose that distinguishing child molesters according to new criteria – that is, whether or not they have been previously associated with their victim – should result in more productive research and provide a better guide for treatment and postdischarge supervision. In our terminology, nonaffiliative child molesters are those offenders who are truly strangers to their victims whereas affiliative child molesters are characterized by an established caregiving relationship with the child for some period prior to the offense. These men, unlike nonaffiliative offenders, engage in a protracted grooming process before offending. Finally, we outline research, treatment, and risk-management strategies relevant to each of our subcategories. 相似文献

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. 相似文献

Adverse childhood experiences are associated with a wide range of behavioral, health, and psychiatric deficits and have recently been used to study the development of serious offending careers. Unfortunately, this research paradigm has largely ignored forensic populations. This study utilized the adverse childhood experiences framework to examine the associations between exposure to violence, victimization, and total adverse childhood experiences on sexual homicide using a sample of 616 incarcerated adult male sexual offenders from Canada 85 of whom committed sexual homicide. Epidemiological tables of odds revealed that a gradient of adverse childhood experiences was associated with sexual homicide, but that the most significant risks were for offenders who had the most extensive abuse histories. In adjusted models, exposure to violence, victimization, and total adverse childhood experiences increased the odds of sexual homicide by 334%, 249%, and 546%, respectively. These effects intensified in models adjusted for childhood enuresis, cruelty to animals, parental abandonment, deviant sexual behaviors, poor self‐image, and sexual problems to 559%, 326%, and 849%, respectively. The adverse childhood experiences framework is a systematic way to organize the criminogenic developmental sequela in sexual homicide. 相似文献

We use 1984–1986 data to estimate lifetime risks of being murdered in each of 50 large American cities and then compare these projections to others made earlier from 1971–1972 and 1976–1977 data. We find strong constancy over time in the average urban resident's murder risk (essentially a 1 in 68 chance of eventually being slain). Moreover, we find a high stability in the dispersion of risk by region, race, and city size and in the relative rankings of the 50 cities by murder risk. We comment briefly about such recent phenomena as the proliferation of crack and the resumption of capital punishment.Throughout this paper, we use the words murder, homicide, killing, and slaying interchangeably, meaning in all cases murder and nonnegligent manslaughter as defined by the FBI. 相似文献
