This diploma thesis is devoted to the investigation methodology of murders. The main emphasis is given to the procedure of the police authority within the investigation of murders. Since this topic is very extensive and the methodology comprises of the great amount of activities, I dedicate this diploma thesis only to the selected areas thereof. The first chapter describes the specification of the crimes against life, in particular legal regulation and related aspects. I focused on the legal regulation in Czech law with respect to a crime of murder, homicide and murder of a new born by its mother. Only marginal attention is given to a crime of negligent manslaughter and a crime of assisting with suicide. The second chapter comprises of the statistics of the committed murders. I analyse the statistics of the numbers of murders committed within the European Union, the Czech Republic and the Ústí region. Another part of the thesis is theoretically orientated. I concentrate on the criminalistics characteristic of a murder and the fundamental aspects thereof - the mode of committing a crime, the personality of a murderer, the personality of a victim and a criminal motive. The following chapter forms the crucial part the diploma thesis in which I analyse typical investigation situations, in particular in...

in English The topic of the thesis is the " The Methodology of Investigation of Murders (selected issues)". The topic is too broad for the limited capacity of the dissertation. While writing the thesis, after the necessary theoretical introduction (which contains the definition of crimes against life, medical definition of death, etc.), I focused only on the initial stage of the investigation of the crime of murder. I specifically focused on the discovery of the body, on securing the crime scene, on autopsy and on the demarcation of investigative versions. Next stage of the investigation is only briefly summarized in the ninth chapter. The thesis is divided into ten chapters. The first chapter explains basic terms, especially murder, murder of a newborn baby by its mother and other crimes against life, such as manslaughter, negligent homicide and assistance to suicide. This chapter also includes medical definition of death, and a brief description of the post-mortem changes. The second chapter consists of brief statistics on the number of murders in the Czech Republic between the periods 2000 to 2012. It contains two graphs; the first graph shows the evolution of the total number of murders each year and their solving. The second graph divides murders according to the specific motives. The third...

This research, situated at the intersection of sociology, science and technology studies and police studies, provides the first sociological account of Crime Scene Investigator (CSI) training in England and Wales. Focusing on the acquisition and everyday enactment of CSI expertise, this qualitative, ethnographic investigation asks (1) what are the roles, practices and expertise of the CSI and (2) how is the CSI’s expertise developed in training and enacted in everyday work. These questions are explored through participant observation at the main training centre for UK CSIs, observation at crime scenes, interviews with trainees during and after their training and visual methods. By unpicking the visible and invisible components of CSI work, I analyse how CSIs are trained to document crime scenes and explore the practices of transforming a potentially relevant object from these locations into artefacts that meet the requirements of courtroom scrutiny. I demonstrate how CSIs engage actively and reflexively with the requirements of different conceptions of objectivity and the changing demands placed on them. They continually and performatively negotiate and delimit multiple boundaries, from the very literal in demarcating a crime scene to claiming their position within the investigative hierarchy in each interaction. Unlike other discussions of boundary work, for the CSI this is iterative, requires constant effort and is embedded in their routine practice. Within police environments, the CSI has scope for such boundary work. In the courtroom, however, crime scene investigation is narrowly defined. This thesis develops our understanding of the CSI and crime scene investigation as a practice. It stresses the significance of taking this actor seriously in any account of forensic science and investigative practices. By viewing the CSI as simply an evidence collector, or not considering her work at all, the expertise and pivotal role of this actor in the meaningful and efficient use of science in policing is blackboxed. My detailed qualitative analysis of the CSI’s role, work and specialist expertise contributes a necessary account of a key actor in the police and criminal justice system.

Bloodstain Pattern Analysis is a rapidly growing area of research in the forensic science field. It is not uncommon for blood to be present on surfaces such as clothing, furniture, carpet, and more, during the commission of a crime. . Research of how blood interacts with different porous surfaces, such as textiles and fabrics, is relatively unexplored in the field of forensic science. Prior to a bloodshed event in which blood may be deposited onto clothing, the fabric may have been laundered in a variety of ways. In this research, swatches of a 100% nylon, water resistant fabric were subjected to seventeen different laundering and soiling processes. The laundering products used included Tide® Liquid Laundry Detergent, Downy® Fabric Softener, Downy® Unstoppables In-Wash Scent Boosters, Bounce® Dryer Sheets, Clorox® Zero Splash Bleach Packs, and OxiClean™ Max Force Laundry Stain Remover. Soiling included wearing swatches of fabric and leaving them in direct sunlight. Whole human blood was inverted, vortexed, then transferred using a disposable transfer pipette. The sample was held 36 in./3 ft. above each sample at a 90-degree angle, using an apparatus made from a flat edge and a protractor to ensure consistency. Blood drops were deposited onto each swatch of fabric, photographed, and microscopically examined. The drip stains were measured and characteristics of the blood, fabric, and the interaction of the two were recorded. Results showed some trends, such as an increased breakdown of fabric structure when bleach was used, and an increase in wicking when treated with scent boosters. Overall, the results were varied in all comparisons.

The topic of my thesis is the methodology of murder investigation. The thesis deals with trace evidence formed during commission of the crime of murder, typical investigative situations faced by crime investigators, and some of the subsequent acts. The aim of this thesis is to familiarize with the offense of murder and the specifics of crime scene investigation. Furthermore, this work provides a summary of the knowledge obtained through the study of monographs, articles in professional journals, and some of the court relevant decisions. Finally, the work further outlines some selected questions and points out the potential problems related to crime scene investigation. The thesis consists of five chapters, which are further divided in to subchapters. Following the introduction, the first chapter describes the murder under criminal law and outlines the various classifications of murder, which include plain murder, murder committed with forethought or prior consideration, and manslaughter. Moreover, the chapter discusses the legislation pertinent to the concept of murder, and explores its roots under the criminal law of England and Wales. The second chapter describes the various disciplines of criminalistics. Additionally, the chapter provides an assessment of murder investigation by exploring...

Literature Review: Expertise, decision making and situation awareness literature have allowed a better understanding of practitioner performance in Engineering, Healthcare and Sport. Discourse is thin in the domain of Crime Scene Examination, although Hierarchical Tasks Analysis, Distributed Cognition, Team Working and Perception have all received attention in recent years. The use of camera technology to uncover performance has also found footing in diverse professions, notably Firefighting and Social Work. Crime Scene Investigator practice is proposed as being a fertile area of study, to make apparent aspects of the work that are tacit, as well as to ascertain if performance metrics in the sector connect with the tacit knowledge expressed in the role. Methodology: This study explored the differences in searching strategies between expert and novice Crime Scene Examiners (n=12) in a simulated environment, before discussing a longitudinal ethnographic examination of how Volume Crime Scene Investigators (n=4) make sense of their practice. Eye-tracker and head-mounted camera technology was used to capture performance from an own point of view perceptive. Nvivo 9 was utilised to collate and code video data, field notes and interview transcriptions. Results & Discussion: Results from verbal protocol analysis and eye-tracker recordings indicate that expert examiners target fewer objects within the crime scene space however spend longer on the objects being viewed. Field study results report that Volume Crime Scene Investigators engage in sharing tacit knowledge, this impacted on their strategies or perception of obtaining forensic evidence. In addition the analysis of coded data from video and verbal protocol reports found that specific physical aspects of examination practice such as fingerprint powdering were aligned to decision making or analysis processes. For example, commenting on the morphology of the surface being examined. Furthermore examiners engaged in and highlighted aspects of their role they felt were important but were not captured in any metrics. Conclusion: It is proposed this new understanding will be of use to those in developing crime scene investigation practitioners as well as presenting related literature on how expertise in the domain can be recognised, elicited and developed in others. This work also sheds light on the value of sector standards for this field along with what is needed to make them more user- friendly for the developing practitioner.

Crime Scene Investigation is without a doubt one of the most important step in criminal proceeding, which allows us to gain a complete picture over events, that really happened. To helps us attain this knowledge, there are certain reflections of perpetrators actions in form of physical evidence, that needs to be found and professionally secured. The task of crime scene investigation team of the relevant department of the Police of the Czech Republic, which intervenes on the scene, is to examine the scene and to provide all the evidence that could help clarify the case. Procedure on the crime scene requires a perfect organization by the head of the crime scene investigation team, which puts high demands on expertise and practical experience of the lead investigator. This procedure is one of the most difficult in the entire criminal proceedings, because even small neglect od duties can have a fatal consequence. This thesis compiles a specific legal texts, that are designated to the students of the law faculties, and for the students of the Police academy of Czech republic, and also knowledge attain from practical guides and guidelines directly for the police officers in Czech republic and tries to create a set of law sources, that will not only compare them, but it will also include authors opinions....

Television shows, in particular CSI: Crime Scene Investigation, have captured the attention of the majority of Americans. As a consequence of these shows, the "CSI effect" has evolved. The CSI effect primarily occurs when people watch crime or law related shows resulting in them gaining an unrealistic expectation of what they think should occur in real trials. This is a concern for prospective jurors who take part in criminal trials. This thesis will reveal how the CSI effect has swept the nation. A large part of this study will be devoted to illustrating how the CSI effect has had an impact on jurors, criminals and the American court system. This thesis will shed light on how television has the power to alter a juror's mind, even if it is a decision that could completely change the defendant's life. This thesis will also examine how legal professionals have strategically begun to mention the CSI effect during their trials in court. Nowadays, it is an ordinary procedure for attorneys, during voir dire, to question prospective jurors about their television viewing habits, as it pertains to CSI. This study will also examine how the producers of CSI discount the effect in its entirety. The creators believe that their creation has been a helpful milestone in the evolution of our criminal justice system.

In contemporary crime drama there has been a shift of main character from the forensic scientist to the consultant. This put the representation of knowledge in a different light. In this study the focus is on how, and what kind of cognitive processes and knowledge are represented in two crime dramas with consultants as main characters; CSI: Crime Scene Investigation and Sherlock. Basing the analysis on concepts of cognitive processes and knowledge, it becomes evident that due to the shift in main character the representation of knowledge also has changed; from an institutionalized and science based view on knowledge to the legitimization of a personal, uncritical and fast way of gathering knowledge.

Crime Scene Investigation offers an innovative approach to learning about crime scene investigation, taking the reader from the first response on the crime scene to documenting crime scene evidence and preparing evidence for courtroom presentation. It includes topics not normally covered in other texts, such as forensic anthropology and pathology, arson and explosives, and the electronic crime scene. Numerous photographs and illustrations complement text material, and a chapter-by-chapter fictional narrative also provides the reader with a qualitative dimension of the crime scene experience. / https://dc.etsu.edu/etsu_books/1085/thumbnail.jpg
