Abstract
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 (n = 732) and unsolved (n = 309) stranger sexual assault cases involving theft. We used binary logistic regression to determine whether behavioral indicators of criminal expertise predicted case status. Findings showed that the most relevant factors related to case solvability were not related to detection avoidance strategies used by the offender, but rather, whether semen evidence was found at the crime scene and the number of sexual acts performed against the victim. Interestingly, cases involving fetish theft were also more likely to remain unsolved. Implications for theory and practice are discussed.

Abstract
This study examined the relationship between the actual level of physical violence in sexual offenses and dark triad, empathic and impulsive personality traits of their perpetrators. Sixty-four male perpetrators of sexual offenses without any serious mental illness were included. A 5-point Likert-type coding system based on Violence Profile for Current Offense was applied to assess the severity of physical violence of each sexual offense. Personality traits of dark triad (psychopathy, Machiavellianism, narcissism), trait empathy and impulsiveness were also evaluated. Multivariate analyses indicated that non-stranger victim, secondary psychopathy, narcissism and empathy could significantly predict greater involvement of physical violence in a sexual offense. In addition, empathy was negatively correlated with all dark triad traits. Sexual violence should be conceptualized in the form of a continuum, and, considering such an approach, offenders with high secondary psychopathy and narcissism may show preference for sexual assaults that are more violent in nature.

Abstract
This study presents psychiatric and forensic characteristics of people accused of a sexual crime and sent for evaluation. Data were drawn from the only institutional psychiatric forensic assessment center in Croatia, during a 9-year period, from January 1, 2010 to December 31, 2018. There were 72 cases of sex offenses: 37 with child victims and 35 with adult victims. People accused of sex offenses with child victims were more often sexually abused during childhood and treated psychiatrically as inpatients. They used alcohol less often. Sex offenders with child victims were diagnosed with narcissistic and antisocial personality disorder, dementia, and pedophilic disorder. Those with adult victims were diagnosed with antisocial personality disorder, alcohol related disorders and dementia. Due to these differences, the management of these two groups of offenders in both mental health and penal systems should be different.

Abstract
Introduction: Sexual violence is a substantial public health problem that is associated with a major impact on victims, and in Croatia, more than half of reported cases of sexual violence involve rape. To help understand their general profiles and consider any implications arising, the aim of this research was to describe the forensic psychiatric characteristics of people charged with rape. Methods: All evaluations of people charged with rape and sent for evaluation at the largest assessment centre in Croatia during the period 2010-2018 were analysed (n = 56). Results: Alleged offences most often took place in a perpetrator or victim's home (71%), while the next most frequent location was the street (15%). Over 80% of alleged victims were known to the accused. Alcohol use and abuse were present in 73% of the accused, and 29% were drinking at the time of the alleged offence. Alcohol-related disorders were presented in 38% of the accused, while 38% had a personal history of drug use, and antisocial and narcissistic personality disorders were present in 48% and 29%, respectively. Psychotic disorders were rare (1.8%). Most of the accused were found to be criminally responsible; however, forensic psychiatric assessment procedures were inadequate when considering psychosexual assessments. Conclusions: Interventions based around public health and education should be considered in this field, and forensic psychiatric assessments should be prioritized for improvement.

Abstract
Although sexual homicide offenders (SHOs) evince personality disorders, few prior studies have examined all personality disorders or utilized control groups of offenders. Drawing on data from 616 adult male sex offenders including 85 who were SHOs, the current study examined the personality profile of the SHOs, by comparing them with a group of violent nonhomicidal sex offenders (VNHSOs) and a group of nonhomicidal sex offenders (NHSOs) on clinical diagnostics of personality disorders and various crime characteristics. The personality profile of SHOs is comprised primarily of Schizoid and Borderline Personality Disorders, and these offenders were significantly likely to select a victim, use a weapon, and use drugs and alcohol before their offenses, but less likely to force their victim to engage in sexual acts or humiliate them. The comorbidity of Schizoid, Borderline, and Antisocial Personality Disorder features presents unique personality dysfunction that facilitates the lethal sexual violence of SHOs relative to their nonhomicidal sexual offender peers.

Abstract
There is a lack of knowledge on mentally disordered sex offenders (MDSOs) targeting adult victims, especially regarding recidivism patterns and the specific subgroup with psychiatric disorders. This paper presents index offense data, clinical data, and recidivism patterns over up to 24 years in a cohort of 146 MDSOs, with and without psychotic disorders, sentenced in Sweden between 1993 and 1997. At the time of the offense, all offenders were affected by clinical, developmental, and criminal history factors. MDSOs with psychotic disorders only marginally differed from those without, the former being less likely to have been institutionalized during childhood, intoxicated during the index offense, or diagnosed with a personality disorder, substance use disorder, or paraphilic disorder. In the cohort, 3.4% of the MDSOs were reconvicted for a new sex offense over 2 years, 9.6% over 5 years, 13.0% over 10 years, and 17.1% over the entire follow-up period of 24 years. In MDSOs with psychotic disorders, no subjects were reconvicted during the first 2 years, while 2.6% were reconvicted over 5 years, 5.3% over 10 years, and 7.9% over 24 years. Recidivism rates for violent and general reoffenses were 39.0% and 37.7%, respectively, for the cohort of MDSOs, and subjects with psychotic disorders reoffended significantly later in general offenses. In conclusion, MDSOs with psychotic disorders showed the same recidivism pattern as MDSOs without psychotic disorders. Furthermore, recidivism research may preferably focus on follow-up periods of 5-10 years since most offenders appear to recidivate within this timeframe.

Abstract
Sexual sadism and psychopathy are often considered synonymous with sexual homicide, but there is limited research on their associates in sexual homicide offenders. Associates of dimensional measures of sexual sadism (Sexual Sadism Scale; SeSaS) and psychopathy (Psychopathy Check List-Revised [PCL-R] total, Factor 1, and Factor 2) were examined in 51 male Scottish cases. Over a third were DSM-IV (Diagnostic and Statistical Manual of Mental Disorders-IV) sexual sadists, just under a third screened in with the SeSaS, and a quarter were "Hare psychopaths." Sexual sadism and PCL-R measures were moderately associated. Sexual sadism predicted control, sexual deviance, and unusual behaviour at crime scenes; attempted homicide and having a co-accused; and multiple sexual homicides and previous sexual offending. PCL-R Factor 1 predicted violent, exploitative, and evading detection behaviours at crime scenes; completed homicide; and previous violent offending. PCL-R Factor 2 predicted impulsive behaviours at crime scenes, substance misuse, and previous general offending. Psychopathy and sexual sadism play key roles in sexual homicide, interact with each other, and determine different aspects of offences and offenders.

Abstract
BACKGROUND Personality disorders (PDs) have been associated with both violent crimes and homicides in many studies. The proportion of PDs among prisoners reaches up to 80%. For male prisoners, the most common PD in the literature is antisocial PD. The aim of this study was to investigate the association between PDs and violent crimes/homicides of male prisoners in Greece. METHODS A sample of 308 subjects was randomly selected from a population of 1300 male prisoners incarcerated in two Greek prisons, one urban and one rural. The presence of PDs was assessed using the Mini International Neuropsychiatric Interview (MINI) and the Personality Diagnostic Questionnaire-4 (PDQ-4). Using logistic regression models PD types and PD "Clusters" (independent variables) were associated with "violent/non-violent crimes" and "homicides/non homicides" (dependent variables). RESULTS "Cluster A" PDs (Paranoid, Schizoid, and Schizotypal) were diagnosed in 16.2%, "Cluster B" (Antisocial, Borderline, Histrionic, Narcissistic) in 66.9% and "Cluster C" (Obsessive-Compulsive, Dependent, Avoidant) in 2.9% of the studied population. Violent crimes and homicides were found significantly associated with "Cluster A" PDs (p = 0.022, p = 0.020). The odds ratio of committing violent crimes was 2.86 times higher for patients with "Cluster A" PDs than the ones without PDs. In addition, the odds ratio of committing homicides was 4.25 times higher for patients with "Cluster A" PDs. In separate analyses, the commitment of violent crimes as well as homicides, was significantly associated with Schizoid (p = 0.043, p = 0.020) and Schizotypal PD (p = 0.017, p = 0.030). CONCLUSIONS The majority of prisoners was found to suffer from a PD, mainly the Antisocial "Cluster B", but the commitment of violent crimes and homicides was significantly associated only with "Cluster A" PDs and specifically with Schizoid and Schizotypal PD.

Abstract
Despite the growing incidence of child exploitation offences, there is little knowledge of the neuropsychological function of older child exploitation material offenders (CEMOs). Given that studies have reported that sex offenders demonstrate deficits attributed to frontal and temporal lobe function, the aim of this pilot study was to investigate the frontotemporal function of older first-time child exploitation material offenders (FTCEMOs). The neuropsychological performance of 11 older FTCEMOs was compared with 34 older historical sex offenders (HSOs) and 32 older nonsex offender (NSO) controls. Forty-five percent of FTCEMOs admitted to a pedophilic interest, which was significantly lower than those reported by HSOs. FTCEMOs provided significantly higher intellectual function scores than HSOs. Results revealed no evidence of mild or major neurocognitive disorder in FTCEMOs. Although the groups were not significantly different, compared with normative data, FTCEMOs reported a high incidence of impairment on a measure of decision making and on a measure of facial emotional recognition.

Abstract
Establishing a model of sexual assault reflecting psychosocial and behavioral 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 associations between killing and sexual arousal. This study defined sexual killing specifying that killing should be directly linked to sexual arousal, and sampled 48 sexual killers, operationalized to include only those engaging in post-mortem sexual interference, with one or two known female victims (non-serial), from prison service national (England and Wales) databases. These sexual killers were compared with 48 non-homicide, life or indeterminately sentenced sexual aggressors on psychological and crime scene characteristics. Contrary to previous research, fatal outcomes were associated with neither stranger victims nor weapon presence; sexual killing was characterized by severity of violence less so than non-fatal assault. Sexual killers more often reported problems with emotional loneliness, empathic concern, and sexual entitlement than the sexual aggressors. Theoretical and applied implications are discussed.

Abstract
INTRODUCTION Personality disorders impair several aspects of intrapsychic and interpersonal life. In particular, mating strategies and sexual functioning could manifest in different and/or dysfunctional ways in people with personality disorders. AIM To describe, through a comprehensive review of the literature, the mating strategies and sexual functioning in patients with personality disorders. METHODS We listed and discussed the principal studies on the relation between mating strategies and sexual functioning in personality disorders. The search strategy used search terms in PubMed for the main studies published from January 2000 to December 2016. MAIN OUTCOME MEASURES We considered two main sections for our selection according to the aim of the present review: mating and sexuality. RESULTS Interesting evidence on mating strategies in personality disorders was found. In particular, the major items were found in the dramatic-unpredictable cluster, with borderline personality disorder being the most studied. In contrast, the bizarre-eccentric cluster had fewer items, with the schizoid personality disorder being the least studied. For sexual behavior, borderline personality seems to be the unique disorder sufficiently studied, with evidence of major histories of child sexual abuse, the presence of sexual dysfunctions, and paraphilic interests. CONCLUSION A large spectrum of mating strategies characterizes different personality disorders, although an inconsistent knowledge about the relation between sexual function and personality disorders emerged from our analysis of the literature. Hence, we invite clinicians and researchers to integrate psychodiagnostic and sexual assessments in psychiatric disciplines for people with personality disorders.

Abstract
This study aims to examine the psychopathological profile of non-homicidal sexual offenders (NHSOs) and homicidal sexual offenders (HSOs). Using an incarcerated sample of 96 NHSOs and 74 HSOs in a federal penitentiary in Canada, these offenders are compared in terms of their offending process, maladaptive personality traits, and paraphilic behaviors. A number of cross-tabular and sequential logistic regression analyses are performed. Relative to their counterpart, findings indicate that a higher percentage of HSOs select a victim of choice, report deviant sexual fantasies, mutilate their victim, and admit to their offense upon apprehension, whereas a higher percentage of NHSOs select victims with distinctive characteristics. In addition, a higher percentage of HSOs manifest paranoid, schizotypal, borderline, histrionic, narcissistic, obsessive-compulsive, and impulsive personality traits, and overall odd and eccentric personality traits compared with NHSOs. Similarly, a higher percentage of HSOs engage in exhibitionism, fetishism, frotteurism, homosexual pedophilia, sexual masochism, and partialism compared with NHSO. These findings are discussed with their implications for offender profiling.

Abstract
Posthumous diagnoses are not uncommonly given to notorious public and historical figures by applying retrospectively, and typically in the absence of the individual being diagnosed, contemporary diagnostic criteria. Although this may be relatively easy and free of consequences when it concerns clear-cut medical conditions, it may have unintended repercussions in the case of psychiatric disorders by creating myths and perpetuating stigma. The case of serial killer Jeffrey Dahmer is a typical example where a somewhat facile and almost syllogistic application of perhaps over-inclusive criteria may have contributed to the legend of solitary murderers as possibly suffering from an autism spectrum condition. Although there may be an understandable human need to explain abominable and heinous behaviors, the lack of the possibility to verify a diagnostic theory and the ill-advised attempt to make a diagnosis fit may de facto be the basis of prejudice and profiling that do not correspond to clinical reality. Although there is no doubt that the brain is the organ of behavior, the authors caution against a budding neo-Lombrosian approach to crime and criminality and against the all too common use of widely differing terms in the study of deviance, such as crime, delinquency, and aggression, the operational use of which, often used interchangeably even in association studies, often erroneously leads to further confusion.

BACKGROUND Information on psychopathological characteristics of sexual homicide offenders is scarce. AIMS To investigate criminal, paraphilic and personality trait differences between serial and single-victim sexual homicide offenders. METHODS All 73 single-victim and 13 serial sexual homicide offenders presenting within a cohort of 671 men sentenced for sexual crimes between 1994 and 2005 and serving their sentence in one high-security Canadian prison and who consented to interview were assessed and compared on their offending patterns, personality pathology and paraphilic behaviours. RESULTS Serial sexual homicide offenders were more likely than the single offenders to report deviant sexual fantasies, having selected victims with distinctive characteristics, to have targeted strangers, structured premeditation and/or verbal humiliation of their victims during the offences. Personality pathology, defined by at least two Diagnostic and Statistical Manual of Mental Disorders IV criteria for personality disorder, was common in both groups, but the serial offenders were more likely to have narcissistic, schizoid and/or obsessive-compulsive traits; they were also more likely to engage in sexual masochism, partialism, homosexual paedophilia, exhibitionism and/or voyeurism. IMPLICATIONS FOR PRACTICE Samples of serial sexual homicide offenders will, fortunately, always be small, and it may be that more could be learned to assist in preventing such crimes if data from several studies or centres were pooled. Our findings suggest that an investigation of sexual homicide offenders should include strategies for evaluating premeditation as well as personality and paraphilic characteristics. Crime scene features that should alert investigators should include similar characteristics between victims and particular aspects of body exposure or organisation.

Abstract
The importance and relevance of forensic practice to societal evolution has increased exponentially in recent years. As society evolves in its understanding of the complex relationships between mankind and society, we rely more and more on the services of forensic experts. This article elucidates the professions of forensic psychiatry and forensic psychology. We examine the two distinct professions from the spectrum of collaboration, integration of services, differences, and similarities. We also compare and contrast the educational background and training requirements for these two professions; and present illustrative scenarios and real life examples of the daily functions of both professionals. Lastly, we present demographic data for the areas of employment, numbers, and geographic distribution of the two professions. Forensic psychiatry is the interface between medicine and law, while forensic psychology is the interface between psychology and law. As such, these professions are mired with complexities and challenged by vulnerabilities. Professionals from both fields can serve as expert witnesses in court and therefore face similar challenges in their course of professional practice. Collaboration between these two professions has the potential to increase both the credibility and utility of forensic services to the courts, the individuals served, and the general public.
