Psychological Profiling of Criminals in Violent Crime Investigations in Nigerian Criminal Justice System

The Nigerian criminal justice system is not entirely ignorant or unaware of the use and the merits of the application of criminal profiling as a tool in crime investigation. 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. However, criminal profiling in Nigeria has not nearly reached the level of recognition, functionality, or institutionalization that it has attained in other jurisdictions. This study aims to examine the feasibility and the practicality of offender profiling in a criminal investigation of violent crimes with a particular focus on the Nigerian criminal justice system. It will also give an expository critique of the loopholes and impediments in the Nigerian criminal justice system and ways criminal profiling can fill up these holes. The research methods employed in this study include a combination of both primary and secondary sources. The work highlighted the effectiveness of this field and thus concluded that criminal investigative analysis should be effectively immersed into the justice system and should also receive as much recognition as it has in other jurisdictions especially in the United States and in major parts of Europe.

Case linkage in Australian serial stranger rape

Purpose 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. Design/methodology/approach 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. Findings 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. Research limitations/implications 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. Practical implications 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. Originality/value 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.

American Serial Rape, 1940–2010

Little is known about the social correlates of serial rape or about trends in offending across time and space in the United States. Furthermore, the limited serial rape scholarship that exists was largely generalized from small, captive samples. The current study aims to amplify our understanding of serial rape by pursuing three fundamental objectives. First, guided by theory and research we propose a new, more precise, and comprehensive conceptualization of serial rape. Next, we draw from media representations of serial rape published in five major American newspapers from 1940 to 2010 to develop an offender social profile and to identify patterns in attack style. Our analysis of a broad and diverse sample of serial offenders described in media accounts ( N = 1,037) produced the following profile estimates—age: 27 years; race/ethnicity: African American, 46%; Caucasian, 29%; Latino, 19%; Asian, 5%. Most offenders were employed in unskilled or semiskilled occupations and the most common attack strategy was the surprise approach (47%). Finally, our data allow us to estimate and interpret historical trends as depicted in media accounts. Our analysis revealed low levels of serial rape in newspaper accounts during the 1940s to 1950s, followed by a steady increase (with periodic decreases) leading to a peak in 1991. This peak is followed by a steady and dramatic decline from 1992 to 2010.

Investigating psychologically motivated crimes: The work of the SAPS Investigative Psychology Unit

The investigation of crimes like serial murder and serial rape requires both experience and proficient detective work. It also requires specialist knowledge to identify the psychological and criminological elements of a serial offence. Within the SAPS, there is a specialist unit that deals with psychologically motivated crimes – the Investigative Psychology Unit (IPU). This article draws attention to the contribution the unit makes to the investigation and prosecution of serial crimes in South Africa.

Reflections on the society’s reaction towards rape victims in Delhi City

In general, most people display stronger beliefs in ?aggravated rape? or ?real rape?; including victims of such rape cases who often identify themselves as ?rape victims? than the victims of ?simple rape?, where none of the aggravating circumstances are present. Despite myths to the contrary these ?simple rape? cases in fact make up the majority of cases. This article considers the implications of ?real rape? and demonstrates how notions about what a ?typical rape? should be, in the form of rape myths, directly impact on societal attitudes towards rape victims and how the media continue to reinforce and perpetuate the notion of real rape through their selective reporting of ?serial rape?, ?stranger rape? or especially ?violent rapes?.
