Practical Implications

This study investigates the role of sexual sadism in the crime-commission process of sexual homicide (SH) involving child victims. A comparison between sadistic and nonsadistic cases involving child victims is conducted by examining the crime context, crime characteristics, methods of killing, body recovery characteristics, and forensic awareness strategies used by offenders. The sample comes from the Sexual Homicide International Database (SHIelD) including 135 cases of solved SHs involving child victims—35 cases with sexual sadism and 101 cases without sexual sadism. The Sexual Homicide Crime Scene Rating Scale for Sexual Sadism (SADSEX-SH) scale is used to identify sexual sadism from crime scene actions. Bivariate and multivariate analysis are performed to examine the differences between the two groups. Findings indicate that sadistic SH of children are characterized by an important level of structured premeditation, the commission of more diversified sexual acts, the use of specific method of killing, and the partial use of forensic awareness strategies. Practical implications in terms of criminal investigations are discussed.

This article—based on a national data set ( N = 173)—focuses on extrafamilial sexual homicides and their spatial mobility. The study combines the location of the crime scene and the offenders and victims’ residences in mobility crime triangles. The findings reveal that most of the homicides fall within the categories of offender mobility and total mobility. Our results show the validity of the distance decay function, with over 70% of homicides occurring within 10 km of the offender’s residence. It appears that under certain circumstances, sexual murderers perceive their surroundings as a safe place to commit a homicide. Finally, the study proposes a four-category spatial typology of sexual homicide.

Serial Sexual Homicide

As with other sexual offenders, sexual homicide perpetrators can be reluctant to talk about their criminal behavior. Therefore, in homicide cases, forensic practitioners frequently rely on crime scene information to identify any sexual behavior associated with the offense. This study aims to identify objective and readily available crime scene information, alongside information about victims and perpetrators, based on 65 cases from England and Wales in the United Kingdom of men convicted of homicide who had committed a non-serial sexual homicide and 64 cases of men convicted of homicide where the available evidence indicated that it was a non-serial non-sexual homicide. Chi-square tests and logistic regression were used to analyze the data. There were few differences in terms of demographic information and criminal histories between the two perpetrator groups. There were crime scene indicators supporting the use of Ressler et al.’s definition of sexual homicide. The victims of sexual homicide were generally found in their home with the lower half of the body exposed and with evidence of vaginal sex. Furthermore, extreme injuries and strangulation were more frequent in sexual homicides. Use of weapon was associated with a non-sexual homicide. Victims of sexual homicide were as likely to know the perpetrator as not. Potential benefits of the characteristics reported to investigators and forensic practitioners tasked with identifying sexual homicides are discussed and areas for further research suggested.

Purpose The purpose of this paper is to investigate whether it is possible to identify different types of sadistic offenders within a sample of sexual homicide offenders (SHOs). Design/methodology/approach The study addresses this research question through the use of two-step hierarchal cluster analysis and binary logistic regression utilizing a sample of 350 cases of sexual homicide from Canada. Findings Results from cluster analysis show that three groups emerge: a non-sadistic group, a mixed group that show evidence of some sadistic behavior and a sadistic group that have high levels of sadistic behavior. Additionally, the sadistic cluster was more likely to destroy or remove evidence at the crime scene than the mixed and non-sadistic cluster and was more likely to leave the victim’s body at a deserted location than the non-sadistic cluster. Originality/value This is the first study to examine the dimensionality of sadism within a sample of SHOs.

This study examined the organized/disorganized model to determine if support exists for two discrete offender types among a sample of 350 Canadian cases of sexual homicide. Variables related to crime scene characteristics and the offender’s modus operandi were tested using latent class analyses. Results suggest that sexual murderers can be separated into two distinct profiles that share similarities with the organized/disorganized dichotomy in terms of the detection avoidance strategies, control, and type of violence used by the offender. The latent class results show further support for the FBI model in relation to the offender’s approach, sexual acts, and postmortem activities.
