Understanding sexual homicide

Abstract

Sexual homicide is a crime that receives much media attention, but one that still has a relatively small research base compared to other crimes. Although the idea of someone deriving sexual gratification from or during the killing of another is an anathema to many, forensic professionals need to understand sexual homicide and the range of circumstances and motivations that lie behind it. This paper explores this complex crime: it illustrates the various definitions and labels used; it suggests that sexual homicide is rare and is committed by individuals who, although having troubled histories, may not differ from other offenders. Then, by examining the various legal and behavioural circumstances in which sexual homicide can occur, this paper illustrates the diversity of sexual homicide and presents it in a more understandable manner. Finally, the paper suggests that knowledge of this diversity is required both for investigative and clinical purposes.     

Performance intelligence,sexual offending and psychopathy

Abstract

Previous studies have suggested that offenders have lowered verbal intelligence compared to their performance intelligence. This phenomenon has been linked traditionally to childhood risk factors (e.g. deficient education, abuse and neglect). Substantial discrepancies between performance intelligence quotients (PIQ) and verbal intelligence quotients (VIQ), however, might also point to neurobiological impairments which may be associated with specific types of criminal behaviour. From the files of 133 male hospitalized offenders, PIQ, VIQ, full scale IQ (FSIQ) scores and Psychopathy Checklist–Revised (PCL-R) scores were derived, along with information about their criminal histories. PIQ over VIQ discrepancies were most pronounced in sexual offenders, particularly in those who had committed sexual crimes against adult victims. Furthermore, PIQ as well as PIQ higher than VIQ discrepancies correlated modestly, but significantly, with PCL-R scores. The results suggest that lower verbal compared to visual and spatial abilities may be connected specifically to egocentric and narcissistic personality traits which, in turn, may be involved in raising the risk of sexual offending.     

Application of the clinical polygraph examination to the assessment,treatment and monitoring of sex offenders

Abstract

Post Conviction Clinical Polygraph Examination Testing (Lie Detector Testing) offers significant opportunities for assessing, treating and monitoring sex offenders. This article briefly reviews the historical development of polygraph techniques including the physiological measures employed, the administration of the polygraph and the interpretation of data collected. Criticisms of polygraphy are explored and information concerning the scientific acceptability of these procedures is given. The current influence of polygraphy in sex offender work is reviewed. Evidence is given of the utility of polygraphy in reducing denial, improving treatment outcomes and more effectively supervising sex offenders on probation or license. Cost benefit considerations are examined, as well as the need for further controlled research and future regulation of the polygraph, if it is to be introduced in Britain. Planned UK Trials are described.     

Revisiting the use of pornography by sexual offenders: Implications for theory and practice

Abstract

Summary: This article examines the extant research on the use of pornography by sexual offenders and some of the debates engendered by such use. The analyses should assist in clarifying a number of issues of concern for all who work in the field of sexual offending.     

The emotional intelligence of adult sex offenders: ability based EI assessment

Abstract

Previous research has suggested that sex offenders are deficient in several areas of emotional functioning such as empathy, emotional perception, emotional management and interpersonal functioning. It is unclear, however, whether sex offenders display a general deficit in emotional functioning or whether their emotional deficits are specific to the circumstances in which offences occur. The present study aimed to provide a broad assessment of the emotional functioning of sex offenders by assessing their emotional intelligence (EI) using an abilities-based emotional intelligence test. Nineteen sex offenders, 18 non-sex offending prisoners and 19 controls were administered the Perception, Assimilation and Management branch subtests from the Mayer Salovey Caruso Emotional Intelligence Test (MSCEIT). The results indicated that the sex offenders were not significantly different than the control group, as assessed by these three branches of the MSCEIT. The results lend support to the suggestion that the emotional deficits displayed by sex offenders may be offence-specific. Implications for the use of the MSCEIT in sex offending populations and the role of EI in relapse prevention programmes are discussed.     

Gender dynamics in the sentencing of white-collar offenders

Theory and empirical research often have agreed that female and white-collar offenders benefit from leniency at the sentencing stage of criminal justice system processing. An untested research question emerging from these distinct bodies of literature is whether the greatest leniency is afforded to female white-collar offenders. We investigate the individual and interactive influences of gender and white-collar conviction on judicial leniency by analyzing Florida sentencing guidelines data from 1994 to 2004 using multinomial logistic regression to model the decision to incarcerate nonviolent economic offenders in jail or prison rather than sentence them to community control. Results indicate that female street offenders sentenced by male judges receive the most lenient sentences, while male offenders are punished the harshest regardless of the gender of the sentencing judge or type of crime. Theoretical and policy implications of the findings are discussed in terms of focal concerns, familial paternalism, and attributional perspectives on judicial decision-making.

“No Remorse,No Repent”: Linking Lack of Remorse to Criminal Offending in a Sample of Serious Adolescent Offenders

Linking emotions to offender decision-making has only recently become of theoretical interest to criminologists, but empirical work in this area has not kept pace nor has such research examined the role of emotions to offending in offender-based samples. Recently, Warr outlined regret as one such emotion that may be useful in thinking about offending. Specifically, he argued that regret may be related to discontinuity in offending, or conversely that a lack of remorse may be related to continuity in offending. This paper uses data from a sample of serious adolescent offenders followed for seven years to investigate this hypothesis. Results provide support for Warr’s hypothesis that remorse-resistant adolescents incur a higher number of re-arrests, while remorse-prone adolescents incur fewer re-arrests, even after controlling for other relevant risk factors.     

Development of impulsivity and risk‐seeking: Implications for the dimensionality and stability of self‐control*

In Gottfredson and Hirschi's self‐control theory, introduced in 1990, they contend that self‐control is a unidimensional construct that develops early in childhood and remains stable throughout the life span. According to findings reported in recent research, however, these arguments are now being challenged, with scholars pointing to ways in which self‐control may be multidimensional in nature and may change beyond the period of alleged stabilization. In this study, we draw on Steinberg's dual systems model, introduced in 2008, to consider this issue further. We examine that model's two key elements of low self‐control—risk‐seeking and impulsivity—to determine whether they are empirically distinguishable from one another and have differing developmental trajectories from childhood to early adulthood. We also consider the consequences of changes in risk‐seeking and impulsivity for within‐individual changes in crime. We examine these issues with data from the National Longitudinal Survey of Youth 1979 (NLSY79) for individuals from 10 to 30 years old. The results of our analyses show support for a multidimensional and dynamic conception of self‐control—from age 10 to age 30, risk‐seeking and impulsivity are empirically distinct and develop in divergent ways that are consistent with the dual systems model. Changes in risk‐seeking and impulsivity also affect changes in crime, but their effects vary with age and changes in the other element. We discuss these findings and their implications for self‐control and the development of life‐course criminology.
