Victims of sexual homicide may be deceived by perpetrators who use a friendly approach to gain access to them, making it difficult for the victim to assess the danger posed by the stranger. When investigating sexual homicides committed by strangers, investigators often lack direct information, including how the perpetrator gained access to the victim. To identify potential predictors of the approach method used in sexual homicides, this study analyzed the preferences and behaviors of sexual murderers who target strangers based on their approach method.

The current study was conducted to confirm the characteristics in sexual homicide and to explore variables that effectively differentiate sexual homicide and nonsexual homicide. Further, newer methods that have received attention in criminology, such as the machine learning method, were used to explore the ideal algorithm for classifying sexual homicide and patterns for sexual homicide in Korea. To do this, 542 homicide cases were analyzed utilizing eight algorithms, and the classification performance of each algorithm was analyzed along with the importance of variables.

Sexual homicide (SH) research has focused on those who commit these crimes and the crimes themselves. This leaves the victim, an equally crucial piece to the puzzle, left as a sort of afterthought, despite the valuable insight that victimology provides to the crime. For the current study, victim information related to their routine activities and lifestyles was taken from an international database containing 662 solved cases of SH.

Although most people have heard the terms 'souvenirs', 'trophies', and 'mementos', discussed in books and movies on the true crimes of sexual murderers, limited research has delved into the phenomenon of theft in sexual homicide (SH). Using a sample of 762 SH cases coming from the Sexual Homicide International Database, the current study examines the crime-commission process of the pre-crime, crime, and post-crime phases of sexual homicide offenders (SHOs) who engaged in theft during a SH. Additionally, this study seeks to determine if a specific type of SHO engages in this behaviour over others.

Purpose Of Review: This review presents recent research on the sexual abuse of older adults and examines this phenomenon from a criminological perspective. Much of the previous work has neglected to consider the entirety of the crime-commission process. Therefore, the work highlighted in this review showcases important information regarding the individual who committed the crime, the victim, and the criminal event as a whole.

Despite the widespread public concern regarding abduction, research on this type of crime is scarce. This lack of research is even more pronounced when looking at cases that end with the death of the victim. In fact, all of the research looking at lethal outcomes in cases of abductions has focused exclusively on child victims and has failed to consider the interactions at the multivariate level between the factors related to the death of the victim.

Background: Developmental victimology theory suggests that developmental features of risk and impact stemming from various types of victimization depend on the age of the child or adolescent.

Objective: A next step is studying the developmental victimization trajectories of individuals involved in sexual crimes by focusing on traumatic events occurring during childhood and adolescence respectively. Building on the developmental victimology perspective, the study's specific aims encompass two key objectives: 1) exploring the diverse trajectories of Adverse Childhood Experiences (ACEs) within a sample of individuals involved in sexual crimes, and 2) assessing whether these ACEs trajectories influence the emergence of distinct high-risk behaviors.

Although most homicides involve the use of a weapon, some offenders still prefer killing with their own hands, using strangulation. In fact, when disaggregating the various types of homicides, sexual homicide offenders appear as having a preference for "personal weapon" to kill the victim. Personal weapons, such as strangulation, asphyxiation, and beating, are the most commonly used killing methods in sexual homicide.

Individuals who commit sexual offenses against children have been shown to be distinctive from adult offenders across both individual and crime characteristics. However, an examination of the literature shows that there are gaps in the research related to whether sadism manifests differently between those who target child compared to adult victims. The current study therefore aimed to explore the differences in the characteristics, crime-commission process, and the dimensions of sadism between sadistic crimes of children ( = 101) compared to those of adults ( = 433).

Criminological theories and widespread assumptions about crime suggest that the modus operandi involved in sexual crimes should have changed over time given various contextual changes, such as better criminological knowledge (e.g., forensic awareness) as well as improved investigative techniques (e.

Research focusing on the role of adverse childhood experience (ACE) of individuals involved in sexual homicide (SH) is scarce. Theoretical models of SH have postulated a connection between these adverse experiences and the development of internal risk factors. However, such assumptions have never been empirically tested.

The focus of the current study is to examine the collection and analysis of traces that are related to crime scene behaviors in sexual homicide cases as well as the factors influencing the solving of these crimes. Using 230 sexual homicide cases from the SHielD database, we computed two neural network models based on the multi-layer perceptron algorithm. First, we determined whether certain crime scene characteristics predicted the collection and analysis of traces (dependent variable for Model 1).

Background: Although sadistic child sexual abuse (SCSA) is rare, existing typologies of child sexual abuse have identified the existence of sadistic subtypes in child molestation, as well in the sexual homicide of children. Nonetheless, no study has sought to determine whether there is heterogeneity in the manifestation of sexual sadism between sadistic child abusers.

Objective: The present study seeks to examine how SCSA manifests differently between offenders, and whether these differences are associated with specific victim, offender, and offense characteristics.

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.

Although there has been considerable variation in the application of expertise to offending populations, one aspect that is widely agreed upon is that expertise is best represented on a continuum from novice to expert. The present study, therefore, investigated criminal expertise in 877 hybrid offenses that involve sexual assault and robbery (i.e.

Past studies on criminal expertise showed that some sexual offenders possess skills related to avoiding detection. An important question that remains unaddressed in the literature, however, is whether unsolved cases can be used as a "proxy" for expertise. The present study sought to provide the first empirical examination of criminal expertise in a sample of solved ( = 732) and unsolved ( = 309) stranger sexual assault cases involving theft.

The phenomenon of "senseless" or "motiveless" homicide refers to homicides that lack an objective external motivation. Despite the unique challenges these homicides pose to police, few empirical studies have been conducted on the topic and existing studies are limited to clinical studies using small samples. To overcome existing empirical shortcomings, the current study used a sample of 319 homicide cases where no motive was established during the investigation to describe the "who" (offender and victim characteristics), "what" (modus operandi, crime characteristics), "where" (encounter, crime, and body recovery associated locations), and "when" (time of the crime) of the entire criminal event.

Filicide is the purposeful killing of one or more children by a parent, step-parent, or other parental figure. Revenge filicide is a poorly understood, rare form of filicide in which a parent murders their child to cause emotional harm to the child's other parent. This descriptive study presents an international case series consisting of 62 revenge filicide cases from nine countries.

The concept of expertise applied to the criminal context assumes that offenders are driven by the abilities to both maximize the payoffs and minimize the risks associated with the crime-commission. This study tested the articulation between these two types of decisions taken by stranger rapists to successfully commit their crime. Specifically, this study aims to identify whether offenders whose modus operandi is indicative of criminal expertise are more likely to use forensic awareness strategies.

Foreign object insertion (FOI) is considered as an unusual behavior and has been defined as the involuntary insertion of any object, by another individual, into any orifice of the victim. Although there is some research on the prevalence and nature of FOI in sexual homicides, there is very little on the characteristics of cases where FOI occurs, and no previous research has compared cases with and without FOI. Given the lack of research on FOI in general and the dissemination of untested ideas regarding the correlates of this behavior specifically, the current study aims to shine new light on sexual homicide cases involving FOI by examining the offender, victim, and crime characteristics associated with FOI.

Background: Research on sexual homicide of child victims is scarce. Studies focusing on the lethal outcome in sexual crimes involving adult victims suggest that those offenders who end up killing their victims present both specific individual and crimecommission process characteristics. Nevertheless, recent studies indicate that findings with adult victims may not adequately explain the lethal outcome in sexual crimes of children.
