The evidential value of crime scene investigation in child rape cases

Coetzee, Theo 31 May 2008 (has links)
The main focus of this dissertation was to evaluate the evidential value of crime scene investigation in child rape cases. There are two kinds of crime scenes that needed to be processed in sexual crimes. Firstly is the location of occurrence and secondly is the victim's body. The crime scene is in any crime the major source of information if correctly approach, but even more so in a child rape investigations. A few crimes rely so heavily upon physical evidence as does the crime of rape. It is therefore essential that all rape investigators have first-class knowledge of proper crime scene investigation methods and techniques. Since crime scenes not properly protected or process may fail the investigation in court and as a result see the suspect acquitted. The following physical evidence could link and assist the investigator to individualise the suspect during thorough crime scene investigation; body fluids such as semen, blood, saliva. Other evidence of physical nature commonly found at crime scenes includes fingerprints, footprints (impression evidence); soil evidence, hair evidence, and anything in general handled or left behind by the rapist at the crime scene. This dissertation strives to provide the Investigator with answers on, how, where, and when to process the crime scene. / Criminology / M.Tech. (Forensic Investigation)

Pointing out of crime scenes : a technique used to link a suspect with a crime

Van der Merwe, Dirk, 1964- 10 1900 (has links)
Crime in South Africa is very close to getting out of control. There is a dramatic increase especially in violent crimes such as murder, hijacking, business robberies, house robberies, rapes and armed robberies where innocent people get killed daily. This has the public shivering in fear. The South African Police Service are responsible for the prevention and investigation of all crimes committed. The Detective Service has the unpleasant task of hunting down the criminals that are responsible for committing these crimes. When a crime is committed and a suspect is arrested, the detectives must use all techniques and methods available to them to connect the suspect with the crime. The positive linkage of a suspect with a crime can lead to a conviction in court and one less criminal on the streets of South Africa. One technique that can be used is pointing out of a crime scene. This research is all about the pointing out of crime scenes. / Police Practice / M. Tech. (Forensic Investigation)

The significance of biological exhibits in investigation of rape cases

Dintwe, Setlhomamaru Isaac 11 1900 (has links)
Democratic and accountable policing is one of the hallmarks of democracy. In a healthy democracy, a police service exists to protect and support the rights of its community by successfully listening to those who are laying complaints and resolving to assist them by bringing the perpetrators to the grinding wheels of justice. Encouraging and ensuring that police officials utilise the most modern means of investigation such as the DNA technology, provides the necessary balance to the exercise of professional discretion and heightened conviction rate by the police officials. The utilisation of biological evidence in investigation of rape cases is such a modern intervention – a way of providing insulation against internal and external interference with the proper and successful investigation of rape cases. / Forensic Investigation / M.

The Net Worth method as technique to quantify income during investigation of financial crime

Botha, Andre Eduan 11 1900 (has links)
It is a well-known fact that criminals derive an income from their illegal activities, live lavish lifestyles, flaunt their wealth for all to see and acquire luxury goods. It is also a well known fact that criminals living from the proceeds of crime do not want to not want to keep financial records of their transactions or illegitimate business for fear of being detected by the authorities and to escape being taxed. It is also a known fact that criminals do not declare income from criminal activities for income tax purposes to the revenue authorities for fear of the illegal origin of the income being made known to the investigating authorities and law enforcement. During the investigation of financial crimes, such as tax evasion and money laundering, it may be required that the amount or value of money, income or assets accrued by a subject is determined in order to determine for instance their liability to pay tax. This research project examines the Net Worth method as an indirect method to circumstantially quantify income during the investigation of financial crime. / Police Practice / M.Tech.

The analysis of a cell phone record as a source of intelligence in the investigation of copper cable theft

Van Niekerk, Anna-Marie 02 1900 (has links)
Copper cable theft (CCT) has a devastating effect on the South African economy, and essential services such as TELKOM, ESKOM AND TRANSNET have been seriously disrupted, due to CCT. This dissertation focuses on the value of the cell phone record as a source of intelligence during (CCT) investigations. The cell phone industry is growing each year, and millions of people worldwide possess a cell phone. Some of these people are involved in criminal activities – which mean that cell phones, with their advanced capabilities, hold evidence which relates to crime. The activation of cell phone activity is contained on a cell phone record, and, when analysed, such information becomes intelligence which has a positive impact on CCT investigations. The purpose of this study is to assist and give guidance to investigators, in order to analyse the cell phone record(s) of CCT thieves. / Criminology and Security Science / M. Tech.

The nature and extent of problems experienced by detectives in the collection, processing and utilisation of crime information at the Rustenburg detective service

Govender, Doraval 31 May 2008 (has links)
This research is concerned with the nature and extent of problems experienced by detectives in the collection, processing and utilisation of crime information for the investigation of crime. The problems gave rise to poor detective performance. The development of information-led policing offers an alternative to the traditional ”reactive” model of investigation of crime. Information-led policing advocates the targeting, gathering, analysis and dissemination of information which is used to inform decisions about the prioritisation of problems and allocation of resources to address the problems (Cope, as quoted by Alison, 2005:93). The purpose of this study is to determine the strengths and weaknesses in the collection, processing and utilisation of crime information at the Rustenburg Detective Service, to find new knowledge that can improve the situation, and to apply the found knowledge to enhance the performance of detectives. / Criminology and Security Science / M.Tech.

Combating financial crime : evaluating the prospect of a whole-of-government approach

Botha, André Eduan 28 June 2018 (has links)
Tax crimes, money laundering and other financial crimes threaten the strategic, political and economic interests of developed and developing countries. The problems encountered by the researcher, is the broad and vague meaning of financial crime compounded by the confusing and ill-considered use of the term by law- and policymakers, politicians, government agencies, agency officials and practitioners weakening effective communication about the phenomenon. The literature shows that given the complexity and multi-faceted nature of financial crime, combating financial crime in all its facets cannot be undertaken by investigative agencies acting in isolation. This study was undertaken with the aim to describe and systematically categorise financial crime and evaluate the prospect of using a Whole-of-Government approach as a framework to harness the capacity of the existing government agencies to combat financial crime more effectively. The research was underpinned by a pragmatic paradigm allowing the researcher to apply a qualitative research methodology using an exploratory and evaluation research design. A detailed review of the literature available nationally and internationally was conducted to establish a conceptual and practical understanding of the issues under investigation. An interview schedule with predetermined questions was developed, pre-tested and administered to participants who are active practitioners involved in combating financial crime in the primary government agencies responsible for combating financial crime based on a purposive sample. The data obtained from the literature and participants were analysed, interpreted and thematically listed according to the frequency with the aim of identifying and comparing similarities and differences between the data. The data was used to develop a system to categorise financial crime systematically based on descriptors used to describe the meaning and application of the term financial crime and to propose practical methods practises and models to combat financial crime more effectively. This research indicates that financial crime can be systematically categorised according to descriptors of the unlawful conduct and that the whole of government approach is a viable approach to combat financial crime more effectively according to the available models for arranging Whole-of-Government work. / Police Science / D.Litt. et Phil.

Use of the biological body-fluid detection dog for investigation of rape cases

Maharaj, Vishyal 02 1900 (has links)
Serious and violent crime in South Africa (SA) has been on the rise in the last few years. The SAPS has been stretched to the maximum in its efforts of trying to stabilise the situation, and has applied various tactics and strategies to eradicate crime. This included, among other things, changes to the basic training programme and reintroduction of specialised units. The success or failure of any criminal investigation will still often depend on the detection and analysis of physical evidence found on the crime scene. Crimes such as rape will always leave behind physical evidence in the form of body-fluids. The detectives need not be experts in order to detect or analyse this physical evidence, but should be experienced enough to know which experts or investigative aids must be used to ensure maximum recovery of the evidence. The purpose of this study was to determine how the Biological Body-fluid Dog (BBFD) can assist detectives in the investigation of rape cases. The researcher has chosen a unique investigative aid in the form of man’s best friend, namely “The Police K9” (canine). The literature shows that trained police dogs have achieved outstanding success in numerous fields around the world, i.e. from narcotic busts, detection of explosives, to countering terrorist threats, to the most chilling search-and-rescue operations. The SAPS has sent its search-and-rescue dogs to many countries abroad to assist in natural disasters. Dogs have been trained by various police agencies for various purposes, but the BBFD dog is unique to the SAPS, and is trained to detect only human blood and semen. The use of K9s in the complex forensic science environment can never be doubted or overlooked. The main problem facing the Booysens SAPS was the low arrest and conviction rate in rape cases, due to a lack of evidence. The researcher hopes to broaden the detectives’ knowledge and skills regarding the objectives of crime investigation, with special focus on detection of physical evidence at rape crime scenes. The BBFD dog is trained to detect minute amounts of body fluid on any type or size of surface, including veld, bush areas, vehicles, carpets, grass, bedrooms, etc. / Police Practice / M.A. (Criminal Justice)

Examining the unique security features of a credit card with the aim of identifying possible fraudulent use

Budhram, Trevor 09 1900 (has links)
The use of credit cards has become a way of life in many parts of the world. Credit cards have also created many new opportunities for criminal activity. It is in this light that organizations such as VISA International have explored a variety of security alternatives by constantly reviewing security measures that may be applied to cards and devote considerable resources to the maintenance of security systems and programmes. These programmes mandated by the association, include uniform card standards, security standards for manufactures, embossing and encoding of cards, standards for mailing the cards and credit background investigations of applicants. These standards assist investigators in examining counterfeit cards and distinguish a counterfeit card from a genuine card. The constant reviewing of security features and methods by the association is to create a card that is technically difficult to alter or counterfeit. / Criminology and Security Science / M.Tech.
