Handwriting as individualisation technique in fraud investigation

Aschendorf, Cynthia Bernice 21 October 2013 (has links)
The aim of this research is to investigate how handwriting as an individualisation technique in fraud investigation can be used by police detectives, SARS investigators and forensic investigation specialists, who are responsible for the investigation and linking the perpetrator, with a view to criminal prosecution. A further intent was to share and introduce a number of important concepts, namely: criminal investigation, identification, individualisation, fraud, evidence and handwriting. The research will explain the sophisticated investigation techniques used to obtain sufficient information to prove the true facts in a court of law. Identification is the collective aspect of the set of characteristics by which an object is definitively recognisable or known, while the individual characteristics establish the individuality of a specific object. Many types of evidence may be used to link an individual with a crime scene, and associate that individual with the performed illegal handling. It also explained that during a cheque/document fraud investigation, it is in most cases the only link to information to trace, identify and individualise the perpetrator, and to obtain a handwriting specimen. It is also discussed how to eliminate a person being a writer of a document, and how to collect, package and mark a disputed document during the investigation. If the investigators use their knowledge of these concepts, it should enhance their investigative skills, and empower them to be become better equipped for the challenges they face in identifying, individualising and linking the perpetrators, in order to ensure successful prosecution and conviction. / Police Practice / M.Tech.

n Ondersoek na ernstige geweldsmisdaad : voorstelle vir opleiding ('n gevalstudie)

Siegelaar, Leslie 12 1900 (has links)
Thesis (MPA)--University of Stellenbosch, 2000. / ENGLISH ABSTRACT: Not a single day passes in South Africa without various violent crimes making the front pages of the local media. The Cape Flats in the Western Cape is one of areas which is seriously affected by violent crime. During the past three years serious violent crimes committed with a firearm have shown a sharp increase. The investigation of such crimes is, just as its prevention, a priority of the SAPS. Investigation of serious violent crime has also changed since the amalgamation of the eleven police agencies in 1996. Whereas the Murder and Robbery Unit was responsible for investigation crimes such as murder and attempted murder using a firearm before 1996, most of these crimes are nowadays investigated by members attached to local detective units. Specialist knowledge is required for the investigation of the said crimes whereas local detectives have only received training in conducting general investigations. The question arising is what is the influence of this training on the investigation of serious crime and more specifically their solution. Against this background the current state of training received by local detectives is investigated as well as the influence on the investigation of serious violent crimes. The SAPS Ravensmead Detective Service is used as a case studyforthis purpose. Practice is compared to the theory and conclusions are drawn about the influence of training on the success rate during the investigation of serious violent crimes. / AFRIKAANSE OPSOMMING: Nie 'n enkele dag gaan in Suid - Afrika verby sonder verskeie geweldsmisdade as voorbladnuus nie. Die Kaapse Vlakte in die Wes -Kaap is van die gebiede wat erg deur ernstige geweldsmisdaad geraak word. Die afgelope drie jaar het ernstige geweldsmisdaad wat gepleeg word deur die gebruik van 'n vuurwapen skerp gestyg. Die ondersoek van dié misdade is net soos die voorkoming daarvan vir die SAPD 'n prioriteit. Die ondersoek van ernstige geweldsmisdaad het na die amalgamering van elf polisie - agentskappe in 1996 verander. Waar die Moord - en - Roofeenheid voor 1996 vir die ondersoek van misdade soos moord en poging tot moord met 'n vuurwapen gepleeg, verantwoordelik was, word die meeste van die misdade nou deur lede verbonde aan plaaslike speureenhede ondersoek. Gespesialiseerde kennis word benodig vir die ondersoek van die genoemde misdade. Plaaslike speurders het slegs opleiding ontvang om algemene ondersoeke waar te neem. Die vraag wat nou ontstaan is wat is die invloed hiervan op die ondersoek van ernstige geweldsmisdaad en meer spesifiek die oplossing daarvan. Teen hierdie agtergrond word ondersoek ingestel na die huidige stand van opleiding van plaaslike speurders en die uitwerking daarvan op die ondersoek van ernstige geweldsmisdaad. Vir hierdie doeleindes word SAPD Ravensmead Speurdiens as gevalstudie gebruik. Die praktyk word met die teorie vergelyk en gevolgtrekkings word gemaak oor die invloed van opleiding op die suksessyfer in die ondersoek van ernstige geweldsmisdaad.

An analysis of the prosecution-led investigation model in murder cases

Myeza, Nkosinathi Wonderboy 15 August 2019 (has links)
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 processing of firearms during investigation of a crime scene

Pillay, Povendran Dorasamy 31 May 2008 (has links)
The study was conducted with the intention of identifying the current procedure employed by investigators for processing firearms evidence at a crime scene. The researcher identified shortcomings which prevent firearm evidence being found to be inadmissible in criminal proceedings. The researcher also analysed other aspects relating to the processing of firearm evidence at a crime scene, namely: Locard principle, identification, individualisation and physical integrity. In order for investigators to be successful in their investigation of cases involving firearms, it is imperative for investigators to have a clear understanding of the basic concepts surrounding firearm evidence processing. It is the strong belief of the researcher that because of improper handling, contamination and lack of integrity pertaining to firearm evidence, such evidence is being found to be inadmissible in criminal proceedings. This negative impact has a roll over effect on the conviction rate for serious crime. / Criminology and Security Science / M. Tech. (Forensic Invesigation)

Enhancing the validity of the SAPS gold fingerprinting database through improved sample-collection techniques

Crundwell, Gordon Rhodes 30 April 2008 (has links)
This study's main focus was to analyse the methodology used by gold mines when obtaining reference samples required for gold fingerprinting analysis. Such methodology is also regulated by legislation in that in terms of the Precious Metals Act 37 of 2005 sect 22(1), "Any producer or any person who imports precious metals must submit to the Forensic Science Laboratory (FSL) of the South African Police Service (SAPS) such specimens of any precious metals produced or imported by him or her as may be prescribed". The gold mines are producers of precious metals, specifically gold, and they are therefore required to submit reference samples, which are then used by the SAPS FSL to maintain a database of gold samples. This database can then be used for comparison purposes during the forensic science of gold fingerprinting. The supporting regulations of the Precious Metals Act, Section 19 stipulate seven requirements for the submission of reference samples and this study intends to give guidelines to security officials employed on the gold mines of South Africa to ensure that these requirements are met and that the validity of the SAPS gold fingerprint database is enhanced through improved sample-collection techniques. The use of gold fingerprinting is part of the forensic investigation process used when trying to establish the origin of gold confiscated as an exhibit during police and mining security crime operations and recoveries, and this allows for victim identification in the resultant criminal trial and proper disposal of recovered gold-bearing materials that are recovered. It is important for the mine security official responsible for reference sample collection to keep in mind that the methodology used when obtaining these samples could be challenged in court and that, therefore, definitive guidelines should be followed to ensure that the most representative samples are collected and that the collection and handing over of samples meet chain of evidence requirements. / Criminology and Security Science / M.Tech (Forensic Investigation)

The use of blood pattern analysis to reconstruct a crime scene

Wiid, Antoinette Bedelia 02 1900 (has links)
The success or failure of any criminal investigation often depends on the recognition of physical evidence left at a crime scene and the proper analysis of that evidence. Crime scenes that involve bloodshed often contain a wealth of information in the form of blood patterns, the location, and its cause. Any criminal investigation has specific tasks, from the time when the crime is reported to the reconstruction of crime scenes. A lot of work needs to be done. Once the investigation starts at the crime scene, BPA needs to be done at the crime scene and the investigating officer must identify this evidential tool. The investigating officer should not necessarily have specialised training in blood pattern analysis, but rather know when to use these experts at their bloody crime scenes. With the interviews and docket analysis done, the researcher found that this was a problem as the investigating officers, either had no knowledge on the subject of BPA or very little knowledge on this research. The purpose of this study was to determine the use of BPA to CSR, and for the investigating officer to realise that it is not just a bloody crime scene, but also contains a wealth of evidence. The researcher had two research questions. Once the investigating officer follows the objectives of criminal investigation, they should be able to have a strong case against the perpetrators. How could BPA be used in the reconstructing of a crime scene? The researcher wanted to bring it to the investigating officers’ attention that it is not just a bloody crime scene, but rather that it contains a wealth of evidence, which can give them a perspective of the movement of both the victim and perpetrator during the commencement of the crime. Regardless of the lack of knowledge of BPA, it is proposed that investigating officers are to be informed, either through station lectures or by yearly refresher workshops and courses of the evidential tool of BPA. When the bloody crime scene is reconstructed with the use of BPA, an insight of what transpired at the crime scene will help them to finalise their cases. For recommendations, it is proposed that investigating officers are to be trained in more in depth courses in criminal investigation as well as crime scene reconstruction and evidence collection using FSL. / Criminology and Security Science / M.Tech.

Investigating serial murder : case linkage methods employed by the South African Police Service

Govender, Pariksha 01 1900 (has links)
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)

Observing a rape crime scene with the intent to identify evidence

Gounden, Manisagaree 09 1900 (has links)
Investigating a crime of rape relies heavily upon physical evidence, which provides the court with tangible objects that are not subject to memory loss. The recognition ofphysical evidence plays a critical role in the investigation process. The first step of crime scene investigation is to conduct observation to locate valuable physical evidence; a task that depends on the skills of the investigating officer. The more common types of physical evidence that could link a suspect to the crime were identified in this study. This dissertation endeavours to provide crime scene investigators with answers on how to conduct observation at a rape crime scene. This research is based on interviews and a literature study, and will furnish insight and information about the observation process at rape crime scenes. The findings of the research may generate guidelines for crime scene observation. Recommendations and conclusions are indicated in the final chapter. / Police Practice / M.

The use of firearm evidence in the investigation of murder

Tshishonga, Mpho 02 1900 (has links)
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)

The analysis of a cheque to identify crime

Kruger, Deidre Jacoba 28 February 2006 (has links)
In this study the main focus of the researcher was to analyse a cheque to identify crime. This study intends to give the forensic investigator a guideline to follow during the analysis of a cheque under investigation. Crimes that could be detected during the analysis of a cheque are fraud, forgery and uttering. Other aspects were also explained to ensure a better understanding of the study, namely: forensic investigation, forensic investigator, identification and crime scenes. Forensic investigation is a systematic search for the truth with the primary purpose of finding a positive solution to a crime. Forensic investigation is not a game of chance, or based on storybook types of coincidences. Therefore, forensic investigators cannot rely on coincidental success to come their way. It is true that luck sometimes plays a role in forensic investigations, but it is the thorough investigator who creates his/her own opportunities and arrives at the right place at the right time. In order for a forensic investigator to strive for excellence, he/she must have a good knowledge of his/her field of work. It is important for the forensic investigator to understand that identification plays an important role in forensic investigation. An additional benefit is derived when one can individualise something because it makes the identification much more valuable. All crime scenes should furthermore be managed in such a way that all physical evidence can be collected in order to ensure successful prosecution and conviction in a court of law. It is the belief of the researcher that because cheques are not acknowledged as crime scenes and therefore not properly handled or protected, many investigations fail in court and the accused are acquitted. / Criminology and Security Science / M.
