In a country where judicial institutions are known to be inefficient and where activists have traditionally not engaged in legal mobilization, what explains the emergence of NGO strategic litigation? The author argues that a change in the legal opportunity structure impacts how activists interact with the legal system. Comparing two states in Mexico, the author demonstrates that the introduction of private prosecution rights opened the door for activists to litigate femicide cases. The emergence of strategic litigation has helped improve compliance with international human rights law and has had a demonstration effect on how to use the law to press for accountability.

Rapid sequence homicide offenders (RSHOs), formerly spree killers, are an understudied population due to the confusion surrounding their classification in relation to serial murderers. The paper aims to discuss this issue.

An exploratory, comparative analysis of 56 RSHOs and 60 serial murderers was conducted on US-based data from 2014 to 2018 derived from the Consolidated Serial Homicide Offender Database to determine similarities and differences between the cohorts.

RSHOs and serial murderers are similar in that they often kill their victims using a singular method, have limited mobility, kill a similar number of victims both known and unknown to them and are both supremely motivated by domestic anger. There is an inverse relationship between serial murderers and RSHOs: as one group increases in prevalence the other decreases.

In order to divert men into more pro-social activities, attention must be dedicated to increasing mental health services that provide them with the tools to diffuse their hatred and couple that with effective gun control strategies and ways to enhance the compromised anger management skills of a generation of volatile men.

Academicians have been hesitant to juxtapose these offenders but based this conclusion on surface-level differences. A reimagining of these categorical structures is needed. The once clear delineation between these cohorts may continue to shrink and synchronize until one subsumes the other.

The purpose of this paper is to propose a methodological approach to increase the clearance rate of cold cases in The Netherlands and to contribute to the development of intelligence-driven criminal investigations in general police practice and within cold case investigations in particular.

This proposal is based on practical investigative experience and academic knowledge.

Reconstructing scenarios helps convert cold case information into intelligence, which is beneficial to law enforcement agencies in terms of time, resources and prioritising cold cases. Intelligence contributes to the formulation of more effective queries and to a more efficient adaptation of new and existing investigation methods, leading to a higher cold case clearance rate. Moreover, scenario reconstruction creates a link between intelligence and investigation, i.e. between science and practice, which adds to the further development of intelligence-driven investigations.

When carrying out scenario reconstructions, practical implications are expected, as intelligence products are currently not or barely used in practice and science is not yet embedded in the investigational practice.

To move from scenario reconstruction to intelligence-driven criminal investigation, the gap between science and the investigational practice needs to be bridged by persons familiar with both. This study hopes to provide the necessary and relevant impetus to this dialogue.

Case linkage theory and practice have received growing empirical support; however, they have yet to be examined fully within Australia. For sexual assault case linkage to be successful, it is assumed that a serial rapist will behave relatively consistently across offences yet distinctively compared to other offenders. The purpose of this paper is to test the underlying principles of case linkage, behavioural consistency and distinctiveness, as well as distinguishing accuracy.

In total, 250 solved stranger rapes by 171 offenders (46 serial rapists, 125 one-off rapists) were taken from Queensland Police Service (QPS) crime records. All possible crime pairings were created and cross-crime similarity was assessed using Jaccard’s coefficient. Receiver operating characteristics (ROC) analysis was used to examine the ability to distinguish between linked and unlinked offence pairs.

Serial linked pairs had the highest Jaccard’s coefficient (0.456), followed by non-serial unlinked (0.253) and finally, serial unlinked pairs (0.247). Within the ROC analysis, an area under the curve value was found of 0.913, indicating excellent distinguishing accuracy. Both the underlying principles of behavioural consistency and distinctiveness were supported through theoretical and practical methods. This paper provides the first analysis of serial rape case linkage in Australia, adding validity to this practice.

The authors wish to acknowledge the support and assistance from the QPS in undertaking this research. The views expressed in this publication are not necessarily those of the QPS and any errors of omission or commission are the responsibility of the authors.

This paper provides validity to the practice of case linkage using a database within Australia. The results of this paper can be used to inform investigators of serial offender behaviours. The theories of offender consistency and distinctiveness are supported, highlighting the importance of behavioural evidence for practitioners. This paper provided a practical increase of the quantity and quality of offences uploaded on the Australian violent and sexual crimes database, which will assist further linkage efforts.

This paper is the first in Australia to examine consistency, distinctiveness and case linkage of serial stranger rape. Thus is contributes significantly not only to an increased understanding of serial rape and case linkage in Australia but also brings Australia closer to modern research practices in this field.

The study aims to examine the effect of detective experience on the likelihood of clearing a homicide, while controlling for additional extralegal and case/investigative characteristics.

This study uses homicide and policing data collected from case files in a mid-sized US city. Detective experience is measured in multiple ways. Analytical models include extralegal variables, case characteristics, and proxies of investigative quality as controls. The study uses logistic regression with a dichotomous clearance outcome.

The results suggest a robust and significant inverse relationship between the years spent as a homicide detective and the likelihood of case closure. However, years of experience with the department overall has a significant and positive relationship to clearance. Investigation-related variables and case characteristics contribute more to model explanatory power than extralegal factors.

The potential role of experience has not been fully explored, with contradictory findings over time. This work builds on previous research to highlight the potential role of experience in clearing cases, while questioning previous assumptions tied to the belief that more experience improves investigative outcomes.

In England and Wales, on average one child every week is a victim of homicide. The purpose of this paper is to explore whether different victim-risk profiles and suspect variables can be differentiated for specific victim ages.

This paper presents a preliminary analysis of more than 1,000 child homicides committed in England and Wales between 1996 and 2013, from data provided through the Homicide Index. Statistical techniques such as cluster analysis were used to identify specific victim-risk profiles and to analyse suspect variables according to the age of victim.

The findings present a clearer picture of the risk-age relationship in child homicide, whereby several specific risk profiles are identified for specific child ages, comprised of crime variables including; likely victim and suspect demographics, the most likely circumstances of the homicide and methods of killing. Using similar techniques, a number of tentative clusters of suspects implicated in child homicide are also described and analysed, with suggestions of further analysis that might prove of value.

The practical implications cannot be understated. For those professionals working in the fields of child protection and criminal investigation the identification of risk profiles promises to provide a back-cloth with which to practice when confronted with complex and distressing child homicide scenarios. This research promises most to those currently training in related professions.

Although the statistical level of risk has been linked with the age of a child (with younger children being most vulnerable to killing by a parent or step-parent and older children most vulnerable to killing by acquaintances and strangers), extant research is yet to progress beyond the identification of broad age-risk categories. The paper concludes with a discussion of the likely implications for those charged with reducing and investigating child homicide and outlines the possibility of future research.

Although many studies have examined the correlates of homicide clearance rates, few analyses have examined the factors related to the clearance of burglary offenses. The purpose of this paper is to address several gaps in the literature to determine if burglary clearance rates are due to discretionary, non-discretionary, and/or neighborhood contextual factors.

Data are analyzed from more than 10,000 burglary incidents in Philadelphia from 2010 using multilevel models to simultaneously test for the influence of multiple perspectives of the factors of crime clearance.

The results indicate that variables representing broken windows enforcement, discretionary factors, and non-discretionary factors are related to the increased likelihood that burglaries are cleared, but processes associated with social disorganization within communities is not.

The findings contribute to the literature by showing that future examinations of the factors of burglary clearance should consider community contextual factors, and specifically, that broken windows police enforcement appears to be a more important predictor of burglary clearance than do factors related to social disorganization theory. As a result, it is suggested that law enforcement also consider their tactics regarding low-level offenses if they wish to address the clearance rate of burglaries.

This analysis is among the first to examine multiple perspectives of the factors of crime clearance on burglary incidents.

The purpose of this paper is to explore the issue of suicide, a violent act against one’s self, as it relates to white- and red-collar crimes. White-collar crime can be described as nonviolent crime committed for financial gain. Red-collar crime describes a situation where a white-collar criminal commits an act of violence, often murder, to silence someone who is in a position to report a fraud they have perpetrated. Previous research has not addressed the issue of suicide, as it relates to white- and red-collar crime.

The analysis is conceptual, focusing on the historical underpinnings of white- and red-collar crime and reviewing the evolution of white-collar criminals. Sources of information consisted of published news media, scholarly articles and articles retrieved from the web.

A suicide may be linked, directly or indirectly, to a financial crime. Law enforcement must be careful not to jump to conclusions, as there is a possibility that a staged suicide has occurred.

Law enforcement individuals may want to consider an additional motive when investigating a suicide, especially when the victim has some type of connection to a known fraud. This type of connection may not be readily apparent and may require a new approach on the part of a law enforcement investigation.

Detective work is a mainstay of modern law enforcement, but its effectiveness has been much less evaluated than patrol work. To explore what is known about effective investigative practices and to identify evidence gaps, the authors assess the current state of empirical research on investigations.

The authors assess the empirical research about the effectiveness of criminal investigations and detective work in resolving cases and improving clearance rates.

The authors’ analysis of the literature produced 80 studies that focus on seven categories of investigations research, which include the impact that case and situational factors, demographic and neighborhood dynamics, organizational policies and practices, investigative effort, technology, patrol officers and community members have on case resolution. The authors’ assessment shows that evaluation research examining the effectiveness of various investigative activities is rare. However, the broader empirical literature indicates that a combination of organizational policies, investigative effort and certain technologies can be promising in improving investigative outcomes even in cases deemed less solvable.

From an evidence-based perspective, this review emphasizes the need for greater transparency, evaluation and accountability of investigative activities given the resources and importance afforded to criminal investigations.

This review is currently the most up-to-date review of the state of the research on what is known about effective investigative practices.
