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.

Serial crime recognition is a critical task. Usually, police officer investigates the serial crime behavior based on their heuristics, evidence or prior information from public. Sometimes, the police officer makes inadequate decision when handling the serial crime problems due to lack of preliminary study on relationship between serial crime and amenities. Therefore, this study explores k-means to identify pattern of surroundings area at serial comersial crime scene. In Malaysia, precisely Selangor, Wilayah Persekutuan Kuala Lumpur and Wilayah Persekutuan Putrjaya, a set data of serial crime including index and non-index, and its surroundings area at crime scene are being investigated. Experimental result shows that ‘hot spot’ amenities such as bank, commercial center, restorant, place of worship, resident and school are highly involved with three types of crime namely house breaking at night, day and robbery without firearm. Furthermore, radius distance with 0.2 km and 0.3 km between the crime scene location and its amenities at surroundings area captured from Safe City Monitoring System are also being evaluated and analyzed. Consequently, our finding helps the police to easily observe and prevent criminal behavior by assigning necessary human resource based on their ‘hot spot’ amenities.

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.
