Conference Paper
Background: Stalking, IPV and Sexual Violence are serious public health issues, where women are disproportionally victimized. However, there is a lack of research on how these forms of violence are linked, stressing the need for more research and the elaboration of evidence-based prevention programmes. The worldwide situation has led to an increase...
Article
Paraphilia is a condition in which the sexual excitement rely on fantasizing and/or participating in unusual sexual behaviours although the line between “normal” and “abnormal” has been disputed. The project aimed to explore which sexual fantasies and behaviours are common and uncommon in the general population. Furthermore, the relationship betwee...
Preprint
Abstract Purpose: Stalking can be defined as a pattern of repeated and unwanted behaviours that cause another person to be afraid. The consequences for the victims can be severe and potentially happen over a long period of time. While stalking is considered as a taxon, all empirical evidence, and an absence of pathognomonic criteria, point toward...
Article
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...
Article
Full-text available
The Federal Bureau of Investigation coined the term ‘emotional cool-off period’ in relation to serial homicide defining it as any amount of time between kills where the perpetrator returns to their everyday life (Douglas et al., 1986). Since the term’s conception, cool-off periods have become a fundamental aspect of defining serial versus non-seria...
Article
Stalking is a significant social issue. The inconsistency as to what defines stalking has resulted in the creation of different methods to measure the crime. However, there has been minimal work done that assesses the severity of individual stalking behaviors. The aim of the present study was to assess the level of stalking behavior in terms of sev...
Article
Purpose The study aimed to develop an empirically driven checklist guiding clinicians in the decision-making process that would enable them to determine the functional role of the killing in a newly proposed classification of sexual homicides. Methods Classical Test Theory, Exploratory Factor Analyses and Two-parameter item response theory were co...
Article
Stalking can be defined as a pattern of repeated, unwanted behaviours by one person to another. These behaviours may take the form of communicative intrusion, third-party contact and physical or sexual assault. The individual stalking behaviours experienced by victims have been found to differ in every case, specifically dependent on their stalker-...
Article
This chapter focuses on the assessment of forensically relevant sexual sadism. Assessing sadism is a complex and challenging task in the course of legal proceedings and in forensic‐clinical settings, given the specific contextual demands at the different stages of the criminal justice process. The same principles that apply generally to effective s...
Article
The study investigated whether different types of sexual homicide perpetrators are more or less skilled at delaying detection. A newly proposed direct/indirect typology was used alongside information about the time of arrest, the frequency of specific precautions as well as the impact of forensic strategies used by the perpetrators to examine skill...
Article
Sexual sadism is assumed to be a crucial factor in sexual homicide. Prevalence estimates vary greatly due to differences in the definition of sexual sadism. A nationwide sample of 350 male perpetrators who had committed a sexual homicide offense against a female 14 years of age or above in England or Wales was assessed based on archival records. Se...
Article
Degree of injury, as measured by the Homicide Injury Scale (HIS), was examined to advance understanding of the dynamics of sexual killing. A total of 350 nonserial, male sexual killers were included, and the different ways that the sexual element of their offenses and the act of killing were connected was accounted for by determining that cases wer...
Chapter
Diversity in the types of offences included in the broad category of sexual murder demands attention in research seeking to understand this form of offending. Further, such an understanding should be situated within the wider context of sexual aggression, especially the factors leading to fatal and non-fatal outcomes. Categorising sexual murder int...
Chapter
This chapter considers what is known about sexual murderers, in relation to subtypes of these perpetrators as well as through comparison of sexual murderers to sexual aggressors who have not killed. Two problems encountered in this field of research are discussed. Namely, that 1) amalgamation of subtypes of sexual murderers in comparison studies in...
Article
Purpose Identifying factors that may predict sexual aggression in the context of directly sexual murder, indirectly sexual murder, and non-fatal outcomes is necessary for advancing a field lacking a substantiated multifactorial theoretical model. Methods Eighty-nine sexual murderers engaging in post mortem sexual interference were compared to 92...
Article
Purpose This paper considered the different ways the sexual element and the act of killing could be connected in sexual homicide cases by assigning each case as belonging to either directly or indirectly related groups. Methods A total of 350 non-serial male sexual killers of females aged 14 years or over, who had been convicted and served a custod...
Article
This 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 analys...
Article
Establishing a model of sexual assault reflecting psychosocial and behavioural characteristics of perpetrators of sexual killing and rape is necessary for development in risk assessment and intervention. Methodological variations in defining sexual killing have amalgamated serial and non-serial offenders and perpetrators with direct and indirect as...

Conference Paper
This presentation will summarize the results of two studies exploring sexual killing which were designed to begin empirically considering operationalization difficulties in sexual homicide research. In the first study, offending pathways of sexual killers were explored with a focus on whether the pathways for those with a previous conviction for ra...
Conference Paper
In order to understand the phenomenon of sexual killing, researchers have compared the perpetrators of these crimes and their offenses with those of non-homicide sexual aggressors. Findings suggesting more similarities than differences between the groups have led some scholars to theorise that sexual killing and sexual aggression occur on the oppos...
Article
Full-text available
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 info...

Research on stalking is moving at a fast pace. In the recent years, research from our lab shows that the so-called predator stalker was not the biggest threat and that the ex-intimate stalker was the most dangerous sub-type (i.e., White et al., 2020). Recently, we published a new scale to guide professionals in the assessment of stalking (i.e., Severity of Stalking Behaviours Scales; Stefanska et al., 2021). Exploratory Factor Analysis and Two-parameter IRT analysis revealed that Stalking seems to be a unidimensional construct, with 6 sub-factors. However, the question remains, is stalking a dimensional construct? A recent study, under review, revealed that stalking presents a dimensional structure and no taxonic peaks emerged. Results were consistent across analyses (MAMBAC, MAXEIG and L-Mode), indicators (CCFI, Curves) and measures (Items, Factors). These results have several implications, ranging from a change in the measurement and assessment of stalking, the research strategies used, to the assessment of risk. The present results suggest that the language and conceptualization of stalking should be modified. Scales that measure stalking should provide adequate discrimination along the entire continuum rather than focusing on putative taxonic boundaries and arbitrary threshold. Our lab is now moving forward and will study the nomological network of stalking and its relationship with PDs, sexual violence and domestic violence, both among the general population and in forensic settings. Divergent and non-redundant analyses will be used to understand the nomological network of stalking across populations, settings and genders. Furthermore, Cross-Validation of previous findings will be conducted. Consistency across procedures, measures, and samples is both a cornerstone and necessary component of a scientific investigation and is at the foundation of Meehl’s philosophy.
