Differences Between Sexual and Nonsexual Homicides of Women in the United States: Findings From the National Violent Death Reporting System

Sexual homicide (SH) is the most severe outcome of sexual violence and disproportionately affects women. While SH is rare (<1% in the U.S.) and gravely understudied, it is among the most violent, feared, and well publicized forms of murder. Thus, examining predictors is pertinent to identifying targets for prevention and response efforts. Secondary analysis of 2015–2018 National Violent Death Reporting System data on 6461 female homicide victims age 20–64 was conducted to determine if SH represents a unique killing characterized by specific offender, victim, and incident profiles. Law enforcement and coroner/medical examiner narratives were reviewed to identify cases with sexual elements ( N=324). Logistic regression estimated odds ratios with 95% confidence intervals. Findings highlight important differences between SH and non-SH. SH victims were more likely to be single (AOR=1.7, p=.006), have a substance abuse problem (AOR=1.4, p=.04), or engaged in prostitution (AOR=10.4, p<.001). SH suspects were more likely to be male (AOR=2.5, p=.04), use an illicit substance in the preceding hours (AOR=1.6, p=.03), or had recent contact with police (AOR=1.6, p=.01). SH was more likely to occur in a hotel/motel (AOR=3.0, p=.002), by asphyxiation (AOR =13.38, p<.001), be perpetrated against an acquaintance (AOR=1.64, p=.007), or be precipitated by another serious crime (AOR=2.1, p<.001). Findings advance our understanding of SH victim, suspect, and incident profiles, which can help to better inform police/investigative practices and crime prevention strategies/interventions as well as to improve how SH cases are managed in correctional programs for offenders who have the opportunity for release back into society.

Futile Sexual Homicide in Nepal: A Case Report

Although cases of sexual offenses are not uncommon in children, they present to the Emergency Department seeking treatment for a medical cause. Sometimes the history of abuse is missed by the treating clinicians who are only focused upon the presenting complaint and not upon the underlying cause. Furthermore, the lack of reporting of sexual abuse in medical literatures makes them a rarity in the Nepalese scenario. We present an uncommon case of a child where the perpetrator who tried to silence her during the sexual intercourse made a futile attempt to kill her cutting her throat with a sickle.

The Unusual Case of Sexual Homicide Against Males: Comparisons and Classification

This study examines the specificities of sexual homicides involving male victims. First, this study aims to identify characteristics specific to SH involving male victims by comparing them to SH involving female victims and determine whether rational choice approach and routine activities theories are useful to explain the crime-commission process. Second, this study aims to provide the first empirical classification of SH involving male victims. The sample used in this research comes from the Sexual Homicide International Database (SHIelD) including 662 cases of cases—100 cases involving male victims and 552 involving female victims. Bivariate and multivariate analysis are performed to examine the differences between the two groups and latent class analysis is used to generate an empirical classification of cases involving male victims. Findings indicate the victim’s gender plays an important role in the different choices made by sexual homicide offenders of male victims to successfully complete their crime. They adapted their crime-commission process to overcome the risks associated with a physical confrontation with a male victim (i.e., target selection, approach strategy, method of killing). Classification analysis suggests that it exists three different types of sexual murderers assaulting male victims: the robber sexual murderer, the sadistic sexual murderer, and the pedophile murderer. This research proposes the first empirical typology of sexual homicide involving male victims and provides both a true picture of the reality and a comprehensive understanding of this phenomenon.

Our love was a two-person game. At least until one of us died, and the other became a murderer: sexual homicide perpetrated by intimate partners

Purpose The analysis of previous studies showed that research pertaining to the examination of the crime scene and Modus Operandi variables in intimate partner homicide (IPH) is scarce. Additionally, to our knowledge, there are no studies investigating sexual homicide perpetrated by intimate partners. This study aims to address that void. Thus, the study examined various components of the crime event and as such, it was exploratory in nature. Design/methodology/approach The study consisted of male sexual killers, who perpetrated against pubescent female victims (14 years old and over) and served a custodial sentence within Her Majesty’s Prison Service in England and Wales. Variables for the study were chosen on the basis of previous research examining IPH and sexual homicide. Descriptive analyses were used in this exploratory study. Findings Descriptive analyses indicated that the most prevalent aggravating circumstances in the lead up to the killing included conflict with the victim before the offence and substance use by the perpetrator around the time of the killing. Stalking was present in approximately a quarter of cases. The results of the analyses of sexual behaviours showed that in 54.9% of the sample the act of killing was purely instrumental whereas in 39.4% of the sample the underlying drive of the act of killing was closely related to the sexual aspect. Originality/value This is a unique study on a topic not yet explored.

Revisiting the anger/sadistic typology of sexual homicide

PurposeThe anger/sadistic model is one of several typologies proposed for sexual homicide events. This paper aims to empirically test this model by examining sexual homicide cases. Empirically validating these typologies provides greater validity and reliability toward the sexual homicide classification systems that are useful in police investigations. Design/methodology/approachSecondary data analysis was conducted using police data on 249 solved sexual homicide cases in Canada from 1948 to 2010. Through a robust classifying method, latent class analysis was used to examine variables from the anger/sadistic typology. Additionally, variables from the pre-crime, crime and post-crime phases were examined in relation to the classes’ external validity. FindingsThree classes emerged, namely, expressive, methodical and instrumental. Expressive and methodical were similar to the anger/sadistic model in terms of the presence of premeditation, victim-offender relationship and body disposal location. Instrumental was characterized by the absence of mutilation on the victim’s body, targeted acquaintances and the use of physical restraints. The three-class typology resembled evidence found in a previous systematic review and also reinforced the notion of heterogeneity in sexual homicide offenses. Originality/valueThis is the first study to empirically test the anger/sadistic typology. Such validation is important given that sexual homicide classification systems can aid in police investigations (e.g. narrowing down the list of potential suspects). Replication of studies is needed to lend credibility to research processes, which, in turn, allows practitioners and policymakers to integrate the results into policies effectively.

Patterns of overkill in sexual homicides

Purpose This paper aims to explore the presence of overkill in sexual homicide. More specifically, the study examines whether overkill is a valid indicator of an organized or disorganized sexual homicide. Moreover, the study tests the presence of various patterns of sexual homicide involving overkill. Design/methodology/approach The sample used in this study consists of 662 cases of extrafamilial SHs with (n = 145) and without (n = 517) evidence of overkill, respectively. A binomial regression was used to compare at the multivariate level the two groups of crimes, while a latent class analysis was used to determine whether overkill could be associated with different patterns of sexual homicide. Findings Findings from bivariate and logistic regression analyses show that the presence of overkill may be associated with both organized and disorganized sexual homicides. Moreover, latent class analysis suggests that there are three distinct patterns of overkill in sexual homicide: impulsive, sadistic and personal. Originality/value This study is the first to empirically analyze overkill in sexual homicides and to propose a classification using crime-commission process characteristics.
