The purpose of this paper is to investigate whether aggression and substance use assessed during treatment differ based on risk level for substance-using male offenders of intimate partner violence (IPV).

Secondary analyses were conducted using data from Easton et al.’s (2017) study on substance-dependent IPV offenders. A cluster analysis was utilized in order to classify participants into typology groups. Analyses of covariance were conducted in order to determine group differences in aggression and substance use during treatment.

The paper provides results-related response to treatment based on offender typology. Results appear to reflect two typology groups with significant differences in psychopathy among groups. High-risk offenders demonstrated higher rates of violence throughout treatment compared to moderate- and low-risk offenders; however, no differences in substance use outcomes were found.

A limitation of the study is the extent to which the results can be generalized beyond substance using IPV offenders. Further investigation of treatment outcomes including alternate measures is needed in order to better translate theoretical typologies to clinical settings.

Results provide support for differentiating treatment for substance-using male offenders of IPV based on typology as those with low/moderate risk level appear to be distinctly different and have different treatment outcomes compared to high risk level offenders.

Although the relationship between risk level and treatment outcomes has been researched with Drug Court Offenders, treatment outcomes based on typology has not been evaluated among substance using male offenders of IPV.

The purpose of this paper is to identify offender typologies based on aspects of the offenders’ psychopathology and their associations with crime scene behaviours using data derived from the National Confidential Enquiry into Suicide and Safety in Mental Health concerning homicides in England and Wales committed by offenders in contact with mental health services in the year preceding the offence (n=759).

The authors used multiple correspondence analysis to investigate the interrelationships between the variables and hierarchical agglomerative clustering to identify offender typologies. Variables describing: the offenders’ mental health histories; the offenders’ mental state at the time of offence; characteristics useful for police investigations; and patterns of crime scene behaviours were included.

Results showed differences in the offenders’ histories in relation to their crime scene behaviours. Further, analyses revealed three homicide typologies: externalising, psychosis and depression.

These typologies may assist the police during homicide investigations by: furthering their understanding of the crime or likely suspect; offering insights into crime patterns; provide advice as to what an offender’s offence behaviour might signify about his/her mental health background. Findings suggest information concerning offender psychopathology may be useful for offender profiling purposes in cases of homicide offenders with schizophrenia, depression and comorbid diagnosis of personality disorder and alcohol/drug dependence.

Empirical studies with an emphasis on offender profiling have almost exclusively focussed on the inference of offender demographic characteristics. This study provides a first step in the exploration of offender psychopathology and its integration to the multivariate analysis of offence information for the purposes of investigative profiling of homicide by identifying the dominant patterns of mental illness within homicidal behaviour.

Intimate partner violence (IPV) perpetrated by women is an infrequently discussed topic. The lack of knowledge about female perpetrators of IPV results institutionally in insufficient prevention training and discursively in inadequate appreciation of the women's realm. Thus, this chapter will examine the debates on female IPV in the area of tension between violence prevalence research and the gender-based approach in social sciences and shows that female IPV as a women's reality of life is not limited to resistance violence and is far more complex. By collecting data from 58 female IPV cases, the author develops a typology of female offenders of IPV. Case files documented by the counsellors at violenTia, a German counselling specialist working with women perpetrating violence in their partnership, were examined. The counsellors' notes in the case files were analysed by methods of the empirically grounded type construction, that is the notes were thematically coded and dimensionalised and the case files were grouped according to empirical regularities, followed by an analysis of the contexts of meaning, the type construction and the characterisation of the types constructed. As per the findings, four types (1–4) and one subtype (3′) of female IPV were developed. The main dimensions of the typology are the structure of violence (asymmetrical/symmetrical), the pattern of violence (systematic/situational), the agency of violence (who has the ability and capacity to use violence) and attribution of meaning to violence (for example, explanations and legitimisation). The author concludes that types of female offenders show strong external heterogeneity. A finding which is important for appropriate treatment settings. Female perpetrators often lack the words to describe violent behaviour and repeatedly have unprocessed trauma. Accordingly, to understand and prevent IPV, it is necessary to widen perspectives on female offenders without reducing them to traditional gender stereotypes.

Previous criminological research has examined the causes and correlates of violent juvenile offending, but failed to explore the developmental taxonomies of crime throughout history. Theoretically, developmental trajectories of offending (i.e. life‐course persistent and adolescence‐limited offenders) should be identifiable irrespective of time and place. This study aims to examine the pre‐offense characteristics of nineteenth‐century American parricide offenders.

Using archival records of two major newspapers (New York Times, Chicago Tribune), the study examines 220 offenders who committed attempted and completed parricides during the latter half of the nineteenth century (1852‐1999).

Results reveal that a small group of adult parricide offenders displayed antisocial tendencies at an early age that persisted into adulthood. These findings are consistent with the developmental literature, thus providing support for identification of pre‐offense characteristics of parricide offenders across historical periods.

The findings reported in this paper are of value to psychologists, historians, and criminologists, for they illuminate the similarities in predictors related to violent behaviors in a small subsection of adult offenders across two centuries.

Most burglaries are property offenses yet some offenders perpetrate burglary for the purpose of violent instrumental crimes. Sexual burglars are distinct from non-sexual burglars because the former seek to rape or sexually abuse victims within the homes they burgle whereas the latter seek theft and material gain. It is unclear to what degree burglars who are armed with firearms or knives represent a type of sexual burglar, or perhaps a more severe type of offender who enters homes not merely to rape a victim, but to perhaps murder them as well. The paper aims to discuss these issues.

Drawing on data from 790 felons in Florida, t-test and negative binomial regression models were used to compare armed burglars to offenders who were not convicted of armed burglary.

Compared to offenders not convicted of armed burglary, armed burglars were involved in significantly more instrumental crimes of violence including first-degree murder, kidnapping, armed rape, armed robbery and assault with intent to murder. Armed burglary may be a marker of extreme instrumental violent offending and warrants further study.

To the authors’ knowledge, this is among the first studies of armed burglary offenders and adds understanding to the heterogeneity of burglary offenders and their criminal careers.

All societies in the modern world are troubled by crime, and the general public is equally fascinated by criminals and fearful of criminal behaviour. In the United Kingdom, events such as the murders of Jack the Ripper, the Yorkshire Ripper and Harold Shipman, and the Soham tragedy, coupled with film and television programmes including Silence of the Lambs, Cracker and Crime Scene Investigation, have fuelled the public's consciousness of the criminal mind.In the fight against crime, the development of offender profiling by the FBI in the USA has further captured people's imagination. The technique was introduced to help law enforcement agencies solve serious crimes such as serial rape or murder, and to a lesser extent arson and property crime. At the heart of profiling lies the belief that by combining psychological principles with crime scene analysis, it is possible to identify the likely characteristics of a perpetrator.Although advances in crime detection are welcomed, the profiling field appears riddled with contradiction and disagreement. Social scientists argue that the discipline is unscientific due to methodologically weak research, while police officers appear sceptical about its benefits for solving crime. In Britain, profiling has witnessed both notable successes, for example Canter's profile of the serial rapist and murderer John Duffy, and dramatic failures, such as the Colin Stagg profile in the Rachel Nickell inquiry. This article reviews the offender profiling literature, examines its applicability in the legal system and identifies areas for future research.

The purpose of this paper is to identify the demographic characteristics, psychological and mental health difficulties, victimisation histories, and offending behaviours of New Zealand child pornography offenders (CPOs) who presented to community-based treatment. Findings are compared with national and international research, and with population norms. Such comparisons can help identify factors that may play a role in the development of child pornography (CP) consumption and potential treatment needs for this population.

A file audit of assessment information and service exit reports was conducted of 46 CPOs who were referred to community-based treatment service in New Zealand.

CPOs were predominantly male, European, and unemployed. Most CPOs were single or separated/divorced, and had no friends or one to five friends, which indicates possible social functioning difficulties, including intimacy. Mental health issues, such as depression and anxiety, loneliness, and childhood abuse appear to be elevated among CPOs in comparison with general population norms. Prior to referral, one-third had engaged in contact sexual offending and most had no non-sexual offending history. CP was often in the form of photos or images, and contained European pre-pubescent females. CPOs’ mental health, social isolation, intimacy deficits, and childhood abuse could be treatment targets for this population.

Limited research has been conducted concerning New Zealand CPOs. Furthermore, studies often do not compare findings with general population norms, which can help identify factors prevalent among the CPOs and treatment needs for this population.

Criminology has produced more than a century of informative research on the social correlates of criminal behavior. Recently, a growing body of theoretical and empirical work has begun to apply evolutionary principles, particularly from life history theory (LHT), to the study of crime. As this body of research continues to grow, it is important that work in this area synthesizes evolutionary principles with the decades of sociological research on the correlates of crime. The paper aims to discuss these issues.

The current paper reviews the brief history of research applying life history concepts to criminology, providing an overview of the underlying framework, exploring examples of empirically testable and tested hypotheses that have been derived from the theory, discussing cautions and criticisms of life history research, and discussing how this area of research can be further integrated with existing theory.

A growing body of research has, with relative consistency, associated indicators of a faster life history strategy with aggression and violence in humans and across the animal kingdom. Research into these associations is still vulnerable to genetic confounding and more research with genetically sensitive designs is needed. The use of hypotheses informed by evolutionary insight and tested with genetically sensitive designs provides the best option for understanding how environmental factors can have an impact on violent and criminal behavior.

The current paper provides an updated review of the growing application of LHT to the study of human behavior and acknowledges criticisms and areas of concern that need to be considered when forming hypotheses for research.

Early classification systems of fire setting have suffered from several limitations, including the lack of empirical validation and the focus mainly on the offender motivation behind this type of crime. More recent research shows that looking at the crime scene behaviors may present a more fruitful approach for helping to solve fire setting offenses. The purpose of this study is to advance current scholarship by developing a new typology of fire setting based on the combination of offender motive and crime scene behaviors.

Latent class analyses were used with a sample of 134 fire setters who committed 275 arsons from the Korean National Police Agency to identify distinct fire setter motivations and crime scene contexts. Chi-square and crosstabulation analysis were then conducted to determine whether crime scene behaviors were associated with distinct offender motives and vice versa. Lastly, to improve the external validity of each of the latent classes, chi-square analyses were performed using variables related to the fire setters' criminal history, sociodemographic characteristics and arson classification.

Five motive subtypes were identified as well as five distinct crime scene contexts in which serial fire setting occurs. A significant association among these classes suggests that it is possible to infer fire setters’ motive from crime scene behavior and vice versa.

This comprehensive typology of fire setters has potential for profiling of unknown offenders as well as for suspect prioritization in police investigations.

Factors influencing crime location choices are not only significant to rape investigations, but they are especially important for geographic profiling. The purpose of the current study is to use temporal, hunting behavior, and modus operandi factors to determine those variables that influence the victim encounter and release locations in serial sexual crime.

Due to the possible correlated nature of serial rapes, the authors use generalized estimating equations (GEE) on a sample of 361 rapes committed by 72 serial sex offenders.

Results indicate that temporal factors, offender hunting behavior, and modus operandi strategies are significant predictors of both the victim encounter and release sites, but the importance of these factors varies depending on whether the location is in a residential land use area, a private site, inside location, or a site that is familiar to the offender.

Police can learn from the current findings and apply them to subsequent rapes within a series by recognizing the timing of the offense, the type of hunting pattern and attack method used in prior sexual crimes committed by the same offender, and modus operandi strategies, to determine the type of location where the rapist is likely to offend next.

This paper is the first attempt to predict factors related to both the encounter and the victim release site in serial rapes using GEE.
