Serial crime is an element of society that continues to disturb and fascinate scholars. There is thus a need to understand the uniqueness of serial murderers and their psychological development. The field of psychobiography is a qualitative approach to uncover the story of an individual life through greater understanding of psychological concepts. Psychobiographical research is invaluable in the application of theory to the finished lives of exemplary or enigmatic individuals to develop and test theories of human development. Jeffrey Lionel Dahmer (1960 – 1994), a cannibalistic serial killer who killed 17 young men, served as the single psychobiographical subject in this study. Dahmer was selected based on interest value, his uniqueness and the lack of a specifically academic and psychologically focused case study on his life. A qualitative psychobiographical research method was utilized in this study. The primary aim of the research was to explore and describe Jeffrey Dahmer’s personality development across his lifespan. This was achieved by applying Erikson’s (1950) psychosocial theory of staged developmental crises to the lifespan developmental process and Adler’s (1929) dynamic individual psychology to provide a more comprehensive idiographic interpretation of Dahmer as an individual. Jeffrey Dahmer’s life history was uncovered in this psychobiographical case study research through the systematic and consistent collection, analysis and interpretation of life history materials, which highlighted five significant historical periods: (a) Childhood of Fantasy, (b) The Quiet Loner, (c) Hiatus – or Build-up, (d) Seeking a Compliant Partner and (e) Arrest, Trial and Death. The two theoretical frameworks were used to discern, transform and reconstruct his life into a coherent and illuminating narrative of his psychological movement through life. Alexander’s (1988) model of identifying salient themes was used to analyze data for analytical generalization (Yin, 1994). A conceptual framework derived from the two theoretical perspectives was constructed to organize and integrate data and to guide the presentation and discussion of the findings of the study in an integrative and comprehensive manner. The findings suggested that both theoretical perspectives considered the biopsychosocial as well as cultural and historical influences of situations and experiences in Dahmer’s personality development throughout the lifespan. Adlerian theory indicated that Dahmer held a socially useless lifestyle whose movement was guided purposively towards a fictional goal xxii of godlikeness through creative, concrete expressions of personal superiority. Eriksonian theory held that Dahmer remained in role confusion, which was viewed as a functional, fragmented identity to survive in society and achieve a fantasy. Thus, both theories indicated, despite their different conceptualizations, that Dahmer’s personality development was ultimately not socially beneficial. The study of Dahmer’s personality development has provided a positive demonstration of the value of both Erikson (1950) and Adler’s (1929) theories to understand the processes of personality development in an individual life. It has further highlighted the uniqueness of individual responses to life tasks and consequently unlocked the possibility of perceiving people and their actions differently. Recommendations were made for future research undertakings that utilize a psychobiographical research design and methodology to uncover, illuminate and reconstruct the lives of enigmatic personalities.

The investigation of crime is one area in which the South African Police Service is measured on. There is no doubt that poor application of investigation methods results in acquittal of criminals or, at worst, failing to identify the perpetrator. In murder cases, the response from the communities who are directly affected is usually unpleasant and intolerable. This is so because murder is a crime against human life. One death in the family will have significant, undesirable implications to the family involved and, to a certain extent, the community. Violent crime such as murder has a negative effect, not only on the family who has lost the loved one, but also has a severe direct impact on the economy. For instance, no potential investors would want to associate themselves with a country where the incidence of violent crimes has become the norm and where the government appears to be reluctant to take tangible actions to remedy the situation. For years, the South African Police Service applied one methodology in murder investigations, even though their crime statistics showed that this type of crime was constantly increasing and required drastic steps to curb it. This study gives a detailed analysis of the prosecution-led investigation model and its feasibility in murder cases. This research was conducted on the basis that this model appears to work successfully in commercial crimes, judging by the conviction rates reported annually by the National Prosecuting Authority. The study discusses the current investigation model used by the South African Police Service in the investigation of murder and compares it to an intelligence-led investigation model. It then examines the meaning of the prosecution-led investigation. Finally, international experiences in terms of criminal investigation and prosecution procedures are discussed and compared with those of South Africa. The researcher explored the models from the selected countries and interviews conducted were used as a foundation for describing and explaining the future application of the findings emanating from this research. Using the qualitative approach, data was gathered by means of a literature review and qualitative interviews with the sampled participants to answer the research questions. The researcher is of the view that this study (analysing the prosecution-led investigation model in murder cases) presents a significant contribution to the development of practical guidelines that can be used to effectively and efficiently investigate murder cases. / Police Practice / D.

The aim of this descriptive research was to determine the methods of case linkage (methods to link murder cases to each other as well as to link the murder series to one offender) employed by the South African Police Service (SAPS) to investigate serial murder in South Africa and to comprehensively explain them. A qualitative approach was employed with a multi-method data collection process which included case study, interviews and literature review in order to gain an in-depth understanding of the subject. The methods of case linkage are explained within three phases of a serial murder investigation: the identification phase, the investigation and apprehension phase, and the trial and sentencing phase. The main findings of the study revealed the need for further training of the SAPS members and the need for a Standing Operating Procedure to be implemented to specifically govern the system of investigation for a serial murder case. / Criminology and Security Science / M.A. (Criminology)

In this dissertation, the researcher wants to establish the use of firearm evidence in the investigation of the crime of murder. Firearm evidence can be of significance to the investigators during murder investigations. To determine the importance of this evidence the researcher has formulated the following research questions to address the research problem:  What is the role of forensic science in the investigation of crimes?  How can firearm evidence be used in the investigation of murder? An empirical research design and qualitative research approach were used for this dissertation. International and national literature sources were consulted and the researcher conducted semi-structured interviews with the investigators from Akasia SAPS, crime scene experts from the Pretoria North LCRC and ballistics experts from the Forensic Science Laboratory in Silverton, Pretoria. The role of forensic science and the use of firearm evidence in the investigation of murder were established. Recommendations have been made for further research on aspects highlighted by the findings. / Police Practice / M. Tech. (Forensic Investigations)

For decades there has been growing interest into the crime of child murders. Emphasis was placed on victims and those at risk. Not much focus was placed on perpetrators and their families. Evidence suggests that the family and social systems play a vital role in determining adult violent behaviour. This qualitative study aims to explore the experiences of convicted child murderers in their family and social system. Data was collected and analysed, using genogram interviews and analysis. Themes were highlighted using hermeneutic thematic analysis, within a post-modern paradigm. Results were presented in the form of genogram analysis and thematic content analysis. Prominent themes that arose were separation, rejection, abuse, neglect and substance abuse. These life experiences together with poor education are some of the characteristics that may have contributed to the child murderers actions towards children. / Psychology / M. A.

The research is concerned with how the post-mortem report can be used as a source of information in the investigation of murder cases to identify crime, individual crimes and trace suspects, etc. The understanding of the post-mortem report, and the information which can be obtained from it, will assist the police investigators to handle murder cases in a professional way. The purpose of this research was to evaluate the existing manner in which police investigators use post-mortem reports in their investigations, with the intention of determining its strengths and weaknesses, and considering how the usage can be improved. Secondly, the researcher wanted to explore how investigators use postmortem reports as a source of information in their investigations. To accomplish this, the researcher perused international and national literature in an attempt to explore the field. The researcher wanted to apply the new research knowledge in order to develop good practice in the field. This has been done by recommending new procedures to enhance performance and to improve the conviction rate in court cases. / Police Practice / M.Tech. (Forensic Investigation)

This study sought to explore the significance of efficient murder crime scene processing. Data were collected through semi-structured interviews conducted with investigators who investigate murder cases in the Nyanga South African Police Service (SAPS) cluster in the Western Cape, to stimulate knowledge of the significance of efficient murder scene processing. A literature study relating to aspects of crime scene management and crime scene processing was conducted. From the results of this research, it appears that participants did realise the significance of efficient murder scene processing. It is, however, apparent that they experienced challenges and shortcomings with regard to efficiently processing murder scenes. Reasons for this are inexperienced investigators, overload of murder scenes to investigate, lack of human resources, and lack of cooperation between investigators and crime scene experts. The study makes recommendations that could assist the Nyanga SAPS cluster in improving the processing of murder scenes. / Police Practice / M. Tech. (Forensic Investigation)

The researcher attempts to establish the significance of video evidence analysis in the investigation of murder cases against the police. The evidence obtained could be crucial and admissible in court and ultimately resulted in the successful prosecution of an accused person. In order for investigators to conduct an effective investigation, it is important that they become familiar with the application of video evidence, its purpose, benefits and shortfalls. In order to achieve the intended goals and objectives of video evidence, the investigators should know how to collect, package, process and analyse video evidence. The clarification and processing of the crime scene of video evidence as well as the identification of a suspect at the scene of crime is very much important and without video evidence it would be difficult to convict an accused person in a court of law. / Police Practice / M.

In this research, the role of forensic science with the use of forensic photography in the crime scene reconstruction process was evaluated. The researcher identified how SAPS detectives and Crime Scene Technicians (CST‟S) are currently conducting crime scene reconstructions by adopting forensic photography; furthermore, other methods in which forensic photography could be used to conduct crime scene reconstructions were explored. The researcher made use of an empirical design, as the information available on the research topic was limited. The empirical design, together with a qualitative research approach, allowed for real-life observations. The simple random sampling method was used to select 20:10 partcipants for this research as follows: Ten (10) detectives that investigate murder cases, and another ten (10) CST‟S that conducted crime scene reconstructions in the Durban Policing Area (DPA). Data was obtained using qualitative data collection methods that included a literature study and interviews. The findings of this research provide that the value of forensic science, as well as the use of forensic photography in the crime scene reconstruction process, was established. Evidently, detectives and CST‟S are not doing everything possible to reconstruct murder crime scenes. For recommendation, this research suggests that SAPS detectives and crime scene technicians (CST'S) adopt the fundamentals of forensic science when reconstructing murder crime scenes. / Criminology and Security Science / M.
