The use of body language (behaviour pattern recognition) in forensic interviewing

Naidoo, Shantell 02 1900 (has links)
With this study, the researcher wants to establish whether investigators are able to effectively interpret, report on, or pay cognisance to body language during interviews, and whether they are sufficiently trained therein. Knowledge of body language can provide the interviewer with vital clues during the interview process. Regardless of the availability of numerous literatures on nonverbal behaviour in interviewing, the application of this knowledge is lacking among investigators. An empirical research design and a qualitative research approach were used for this research. National and international literature sources were consulted, and the researcher conducted interviews with two experts, knowledgeable investigators and semi-structured interviews with detectives from the East London South African Police Service (SAPS) and forensic investigators from the Special Investigating Unit (SIU) in East London. The importance of the skill of interpreting body language during forensic interviewing was established. Evidently, many investigators do not apply their knowledge and skill to enhance the outcomes of a forensic interview. / Criminology and Security Science / M. Tech. (Forensic Investigation)

A critical analysis of the procedures followed in child rape cases in Mpumalanga Province

Boodhoo, Vinesh 02 1900 (has links)
This study reflects a critical analysis of the procedures followed in child rape cases in Mpumalanga Province and in the process to enhance investigative capabilities with sound detective development. Empirical research was conducted with a literature review, docket analysis and interviews as methods to obtain information where the following important aspects were addressed: an overview of the field of forensic investigation, the shortcomings with regard to child rape investigations and correct procedures for conducting child rape investigations formulated. The study found that generally rape cases were not properly investigated, correct procedures were not followed (biological/physical evidence was not readily identified nor correctly handled) and applicable directives pertaining to child rape investigations not complied with. Investigators had a narrow understanding of the concept forensic investigation. In child rape investigations it would be of more evidential value and reliable to collect physical evidence such as blood, semen, vaginal fluids and saliva as the child’s testimony at court might not be reliable, particularly when subjected to cross examination. Rape is both a contact crime as well as a psychologically motivated crime and both aspects of the trauma needs attention during the investigation process. Crimes against women and children are also a national concern, thus making child rape a priority crime for the South African Police Service. For any successful prosecution it is necessary that policy and correct procedures are not compromised but rather strictly adhered to. The Locard Principle in relation to physical evidence such as body fluids at the crime scene needs to be focussed on during the investigation process. The research suggests that the current standing operating procedures be amended to include the critical aspects of child rape investigation such as processing of the crime scene, the search for biological evidence as well as the packaging and preservation of biological evidence. / Police Practice / M.

The value of the automated fingerprint identification system as a technique in the identification of suspects

Mokwele, Madimetja Edward 02 1900 (has links)
This research is concerned with the value of the Automated Fingerprint Identification System (AFIS) as a technique in the identification of suspects. A problem was identified in the withdrawal of cases where suspects had been identified by means of fingerprints. The study attempted to determine the value of AFIS in the identification of suspects, to find new knowledge that could improve the situation and suggest ways to apply this knowledge to enhance the performance of AFIS experts, criminal investigators and the prosecution in a court of law. The study adopted a multi-method approach to data collection, with the researcher using a literature review, docket analysis and interviews with AFIS experts from Limpopo Province as his sources of data. The results of the study showed that AFIS is a valuable system for the identification of fingerprints in that it is fast and accurate but that in South Africa AFIS experts encounter a number of challenges with the system. The main challenges identified were the potential for the system to be attacked by computer hackers; the slowness of creating an SAPS 69 record, particularly when dealing with prints of poor quality; which leads to cases being closed where AFIS experts’ evidence is not tested/accepted; and the fact that in South Africa AFIS is not applied across government departments, which would allow a more comprehensive database. On the basis of these findings, the study recommends that steps be taken to improve the quality of prints taken at crime scenes, that attention be paid to speeding up the process of dealing with the relevant SAPS 69 records, that investigators and prosecutors be informed about the AFIS process and that the AFIS database be extended to include the fingerprints of all South Africans and immigrants to the country. Lastly, the study suggests that the databases of government departments such as Home Affairs, Public Works Roads & Transport and Safety Security & Liaison (Traffics) be combined to form one national database. / Police Practice / M.

An evaluation of identification methods used in the investigation of counterfeit card fraud

Geldenhuys, Nicolaas D. C. 02 1900 (has links)
Today, the use of one's bank card to pay or withdraw money is common. Modern technology provides us with the convenience of instant transactions at the automated teller machine or point of sale but unfortunately, it has also brought the reality and risk of card skimming and counterfeit card fraud. Criminals have become very efficient and technologically advanced in skimming and counterfeiting cards, to such an extent that counterfeit card fraud has become a significant threat to the public, banking, retail and business in South Africa. Counterfeit card fraud is a complex, multi-faceted crime, requiring specific skills and knowledge of card counterfeiting methods from police and bank investigators. The scope of its investigation is wide. It includes different crime scenes and offenders, sophisticated equipment and various aspects that need to be identified positively. Investigators find it difficult to identify perpetrators and certain aspects unique to this crime and, as a result, many investigations are unsuccessful. This research endeavours to establish what identification methods are available to investigators and which are effective. / Police Practice / M. Tech. (Forensic Investigation)

An analysis of the importance of semen in investigation of rape cases at Venda (Thohoyandou)

Mulaudzi, Ratshilumela 27 February 2020 (has links)
The use of technology and science in the investigation of crime plays a major role in the resolution of complicated cases that cannot be solved by means of other available evidence during the prosecution of rape cases. The study details the importance of semen in investigation of rape cases and emphasizes that semen discovered during the investigation must be analysed in all cases of rape and used as evidence in court. The use of semen as evidence in the investigation of rape cases is a modern intervention aimed at producing evidence that is reliable and relevant. / Criminology and Security Science / M. Tech.

A comparison of the performance of three multivariate methods in investigating the effects of province and power usage on the amounts of five power modes in South Africa

Kanyama, Busanga Jerome 06 1900 (has links)
Researchers perform multivariate techniques MANOVA, discriminant analysis and factor analysis. The most common applications in social science are to identify and test the effects from the analysis. The use of this multivariate technique is uncommon in investigating the effects of power usage and Province in South Africa on the amounts of the five power modes. This dissertation discusses this issue, the methodology and practical problems of the three multivariate techniques. The author examines the applications of each technique in social public research and comparisons are made between the three multivariate techniques. This dissertation concludes with a discussion of both the concepts of the present multivariate techniques and the results found on the use of the three multivariate techniques in the energy household consumption. The author recommends focusing on the hypotheses of the study or typical questions surrounding of each technique to guide the researcher in choosing the appropriate analysis in the social research, as each technique has some strengths and limitations. / Statistics / M.

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 / M.Tech. (Forensic Investigation)

Utilising advanced accounting software to trace the reintegration of proceeds of crime, from underground banking into the formal banking system

Botes, Christo 30 April 2008 (has links)
The aim of this paper is to research how advanced accounting software can be used by police detectives, financial risk specialists and forensic investigation specialists, who are responsible for the investigation and tracing of the reintegration of proceeds of crime, from underground banking into formal banking system (pro active and reactive money laundering investigation) with a view on criminal prosecution. The research started of by looking at the basic ways how proceeds of crime are smuggled before it is integrated into the formal banking system. In that context, the phenomenon of Underground banking was researched. Currency smuggling, Hawala currency transfer schemes and the way in which it is used to move proceeds of crime were discussed in detail. Thereafter Formal banking and the way in which proceeds of crime is reintegrated from underground banking structures into formal banking systems were discussed. The use of advanced accounting software to trace the point where proceeds of crime are reintegrated into formal banking were researched extensively. Accounting software and investigative techniques on how to trace financial transactions which might be tainted with proceeds of crime were discussed. Accounting software which can be used on office computers such as laptops were discussed and more advanced automated systems which can be used to trace proceeds of crime transactions in the formal banking systems were also discussed. In specific, the investigative techniques on how to use these systems as investigative tools were discussed in great detail. This research paper gives a truly unique perspective on the financial investigative and analytical angle on proceeds of crime and money laundering detection. / Criminal Justice / 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 / M.Tech.

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)
