“…For example, difficulties remain with definition and objective identification criteria, sample selection bias is unavoidable, base rates are low, and researchers face a particular challenge in the reliability and availability of information pertaining to this population (Chan, 2015;Clarke & Carter, 2000). (Beauregard & Proulx, 2002;Beech, Fisher, & Ward, 2005;Myers et al, 1999;Stefanska et al, 2015). Perpetrators of these grievance-driven offenses kill in the context of sexual activity, which may or may not be immediately assaultive; often anger precedes or is triggered in a consensual situation (Stefanska et al, 2015).…”

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 non-post mortem sexual interference sexual murderers and 72 rapists on developmental factors, adult lifestyle, and criminal history. An overall model was built using a series of multinomial logistic regression analyses. Results. Unlike rapists, both groups of sexual murderers experienced a lack of success in sexually intimate relationships. Perpetrators of post mortem sexual interference were rarely necrophiles, but having a history of sadistic behaviors or interests uniquely predicted sexual murder involving post mortem sexual interference. Chronic violent and sexual offending was characteristic of rapists. Psychopathy, measured using the screening version of the Psychopathy Checklist (Hart, Cox, & Hare, 1995), was not predictive of any outcome. Conclusion. Results support criticism of existing theoretical models; that they do not apply to non-sadistic sexual murder. Findings are discussed in relation to gaps in theoretical understanding of sexual murder, and concerning implications for forensic policies and practice.

“…Beech, Fisher, and Ward (2005) types were based on motive: urges to rape and/or murder, grievance, or motivated to sexually offend. Similarly, Stefanska, Carter, Higgs, Bishop, and Beech (2015) identified deviancy driven, grievance driven and sexually driven types. While attempting to test two different typologies, Sewall, Krupp, and Lalumière (2013) found three different types of serial sexual homicide offenders using cluster analysis labelled sadistic, competitively disadvantaged and slashers, as well as a fourth heterogeneous group.…”

“…Although previous studies have compared different types of sexual homicide across countries , no previous study has empirically compared sexual homicides across countries using a sophisticated method such as LCA to improve classification accuracy. Many of the previously identified typologies furthermore utilises variables unlikely to be available to the police at the time of investigation, particularly relating to the offender, such as for instance social skills or school performance (Sewall et al, 2013), psychometric measures (Stefanska et al, 2015) or affect associated with the crime (Beauregard & Proulx, 2002). While valuable when identifying types of sexual homicide, the investigative utility of such typologies is limited.…”

Although similar subtypes of sexual homicide have been described crossnationally, no study has directly examined whether two samples from different jurisdictions are comparable. This study therefore aimed to examine whether any substantively meaningful subtypes of sexual homicide cases could be identified in each sample, and if so, whether these subtypes were similar across jurisdictions. Two samples of male sexual homicide offenders were compared: a Scottish sample (n = 89) and a Canadian sample (n = 150). Subtypes were identified in each sample using LCA, identifying a 3-class solution in each sample. Despite differences between samples on the bivariate level, two very similar subtypes (Controlled-Organized and Diverse) emerged in both samples. Despite differences at the bivariate level, the similarities at the multivariate level indicate similarities in underlying offence pathways which underpin heterogeneity in sexual homicide offenders. The similarities between the subtypes identified suggests potential universality of types of sexual homicides cross-nationally.

“…This analytical strategy has been used further to develop typologies of a range of offenders, including nonserial sexual killers (Stefanska, Carter, Higgs, Bishopp, & Beech, ), sex offenders who target marginalized victims (Horan & Beauregard, ), extrafamilial sexual aggressors against women (Proulx, Beauregard, Lussier, & Leclerc, ), intrafamilial child sex offenders (Leclerc, Beauregard, Forouzan, & Proulx, ), extrafamilial sexual aggressors against adolescents (Brouillette‐Alarie & Proulx, ), and marital rapists (Proulx & Beauregard, 2014). Hence, there are grounds to believe that this strategy can be applied to develop a meaningful typology of person–environment interactions that span the lone‐actor terrorism offending process.…”

Research Summary:The lone-actor terrorist population can be extremely heterogeneous and difficult to detect. Intelligence is vital to countering this threat. We devise a typology of person-exposure patterns (PEPs) that could serve as a framework for intelligence gathering and threat assessment. We use cluster analysis and a risk analysis framework (RAF) to identify relations among three components: propensity, situation, and network.The results of the analysis reveal four PEPs: solitary, susceptible, situational, and selection. The solitary PEP lacks common indicators of a propensity to pursue terrorist action. The susceptible PEP reveals cognitive susceptibility, manifesting as mental illness, to be a key factor in the emergence of a terrorist propensity. The situational PEP demonstrates how situational stressors may act as warnings of acceleration toward violent action. Lastly, the selection PEP demonstrates higher frequencies of leakage and antecedent violent behaviors.Policy Implications: Our findings have two key policy implications. First, given the multifinality of terrorism risk indicators, we suggest a move toward a structuredprofessional judgement approach to the risk analysis of lone-actor terrorists. Second, we present the PEP typology as a framework for intelligence gathering. Existing frameworks are predominantly focused on mobilization 452 CLEMMOW ET AL.indicators. We suggest expanding data collection to include propensity and situational indicators, as operationalized here, and using the PEP typology to inform decisions about the emergence of the motivation to commit an attack. To do so, it is necessary to pursue a multiagency approach to intelligence gathering.
