Sexual homicides (SHs) demand nuanced research for effective prevention, treatment, risk assessment and theoretical insights. Intimate‐partner sexual homicides (IPSHs), comprising approximately 20% of SHs, have received limited attention. This study compares IPSHs (n = 56) and non‐intimate partner sexual homicides (NIPSHs) (n = 236) in Australia and New Zealand by investigating offender, victim, and crime‐scene characteristics. While IPSH perpetrators were typically older, separated, and had prior domestic violence convictions, victims were more often non‐white with histories of domestic violence and substance use. Although crime‐scene locations and post‐offence behaviours differed, similar crime scene behaviours were displayed across offender groups, which seemed to be routed in different underlying motives. Whereas drivers of IPSH commonly were grievance and anger, associated with offences occurring after arguments, drivers for NIPSH were more often sexual deviance and sadism. Overall, IPSH encompasses aspects of domestic violence, homicide, and sexual violence, distinguishing it from SH. [ABSTRACT FROM AUTHOR]

The present study examined distinctions between child (n = 30) and adult (n = 212) sexual homicide offenders (SHOs) in Australia and New Zealand, contributing to the limited international research on the subject. Data, primarily sourced from judges' sentencing comments on AustLII and New Zealand Legal Information Institute, revealed significant differences. Child SHOs displayed elevated rates of pedophilia, sexual deviance, and adverse childhood experiences, including sexual abuse. They were more likely to be married, cohabitate, and target familial victims. Their crimes were more often committed during daylight and outdoors, involving tactics such as victim conning, restraints, strangulation, and hiding victim's bodies. No significant group differences emerged regarding offenders' psychopathy or sexual sadism scores. Results were interpreted in line with child SHOs' deviant sexual preferences and the routine activity theory. The study, as the first investigating child sexual homicides in Australia and New Zealand, sets the foundation for an evidence‐based approach to policy and practice. [ABSTRACT FROM AUTHOR]

Research on female sexual homicide has been very scarce. In Europe, it has rarely been examined, and in Scotland, it has never previously been studied. This exploratory study aims to examine the characteristics of sexual homicides involving female offenders between 1990 and 2015 in Scotland. Using data from the Scottish Homicide Database between 1990 and 2015, female sexual homicides (n = 7) were compared to nonsexual homicides committed by females (n = 106) and to sexual homicides committed by men (n = 89) using Fisher's exact tests. The findings show that although female sexual homicide offenders are similar to both female nonsexual homicide offenders and male sexual homicide offenders in certain aspects, there are important differences that distinguish sexual homicides involving female offenders from both groups. Female sexual homicide offenders can arguably be seen as a distinct group of offenders, with specific characteristics and specific needs. [ABSTRACT FROM AUTHOR]

Background International literature is consistent on there being a significant relationship between psychosis and violence, less so on its extent and nature, but two main presentational types are increasingly recognized. In one, people are unremarkable before onset of illness and psychotic symptoms commonly drive violence; in the other, psychosis is preceded by childhood conduct problems, associated with personality disorder, and psychotic symptoms seem less relevant. Aims To explore the extent to which variations in aspects of social and service context in different jurisdictions affect presentational type among people admitted to high security hospitals. Hypotheses There will be differences between jurisdictions in proportions of patients with pure psychosis or with psychosis and antecedent personality disorder, but symptom drive to violence will be more common in the pure psychosis group regardless of social, legal and service context. Method Independently conducted record studies were used to compare high security hospital patients with psychosis in Scotland and England, all resident between 25 August 1992 and 13 August 1993. Results The cohorts were similar in offence histories, predominance of schizophrenia, age at first hospitalization for psychosis and first high security hospitalization. More Scottish patients had co-morbid substance misuse diagnoses and/or personality disorder than patients in England. Psychotic symptom drive to the index offence was, however, four times more likely in the pure psychosis groups, regardless of sex, ethnic group or country. Scottish patients spent less time in high security after the index act. Conclusions Our hypotheses were sustained. Knowledge about lifestyle before onset of psychosis is important for interpreting literature on how psychotic symptoms relate to violence. This may also influence longer term outcome, although the shorter length of secure hospital stay in Scotland was perhaps affected more by greater availability of open ‘step-down’ beds.
