An analysis of Korean homicide crime-scene actions

Recent studies have focused on how different styles of homicides will be reflected in the different types of behaviors committed by offenders at a crime scene. It is suggested that these different types of behaviors best be understood using two frameworks, expressive/instrumental aggression and planned/unplanned violence, to analyze the way the offender acts at the crime scene. Multidimensional analysis is carried out on the crime-scene actions of 70 Korean homicides. The proposed frameworks are found to be a useful way of classifying homicide offenses, assigning 80% of homicides to a dominant theme. Results also indicate that behavioral differences can be related to the differences in the offender-victim relationship. Finally, implications and suggestions for future research are discussed.     

Differentiating sexual violence: A comparison of sexual homicide and rape

Abstract

The present study sought to identify consistent patterns in the actions of sexually violent offenders to determine whether sexual homicide and rape reflect different behavioral emphasis of a single thematic model of sexual assault. Crime scene behaviors of 74 (37 sexual homicides and 37 rapes) solved cases of sexual assaults were compared, and results of a multi-dimensional analysis revealed three thematic styles of interacting with the victim during a sexual assault (Exploit, Control, and Violent). Further analysis indicated that offender–victim interactions in sexual homicide and rape are predominantly distinguished by the degree of violence, such that behaviors associated with each type of offense were found to occur in two discrete areas along a single continuum. Findings are discussed in terms of producing a general framework for understanding sexual violent interactions.     

Prostitute homicides: a descriptive study

It has been estimated that women involved in street prostitution are 60 to 100 times more likely to be murdered than are nonprostitute females. In addition, homicides of prostitutes are notoriously difficult to investigate and, as such, many cases remain unsolved. Despite this large risk factor, little literature exists on homicides of prostitutes, and there is a lack of basic statistics and knowledge regarding this very specific victim group that could possibly help investigators. The aim of the current study is to conduct an exploratory study to explore the key characteristics of this group and how they differ from other subgroups of homicide. Forty-six cases of U.K. prostitute homicides are analyzed and compared to 59 male offender-female victim nonsexual homicide cases and 17 male offender-female victim sexual homicide cases.     

A Multidimensional Approach to Ascertaining Individual Differentiation and Consistency in Serial Sexual Assault: Is It Time to Redefine and Refine?

Whilst investigative use of behavioural evidence to help link and solve serial offences has long been in use, the empirical and theoretical grounds for whether and how to use this evidence effectively have begun to emerge only in recent decades. The present study empirically tested (a) the potential for effectively differentiating between rape offence crime scenes using quantitative and qualitative distinctions within the behavioural dimensions of control, violence, and sexual activity, and (b) the extent to which redefining behavioural consistency more broadly to include dynamic trajectories of behavioural change may be more effective than limiting this definition to behavioural stability. Results confirmed that sexual offences can be successfully differentiated based on the specific degree and subtype of these behavioural dimensions present in each crime scene. The analysis of consistency and behavioural trajectories showed that whilst none of the offenders exhibited complete consistency across behavioural dimensions, a subsample of offenders remained fully consistent in at least one. Furthermore, of those who were not consistent, the vast majority followed an identifiable trajectory of change. Findings are discussed in the context of psychological theories of behavioural consistency as well as practical aspects of advancing the utility of behavioural linkage.
