Bloodstain Patterns: Identification, Interpretation and Application combines material from Blood Dynamics (2001) and Bloodstain Pattern Evidence (2007) with updated case work and scientific advances from medical and hard sciences. The text expands coverage of such areas as arterial damage pattern identification, staging of crime scenes, legal applications and problems from both sides of the bench, and extending teaching and training to those outside criminal justice. With violent offenders more aware of crime scene investigation techniques and attempting to frame others, the text expands outdated basic training programs that are insufficient to identify attempts to confuse the investigation. This book clarifies previous understandings as well as bridges the gap toward future advance courses. Based on the work of Paul Leland Kirk, the book’s focus is on first line investigators’ accuracy in identifying specific bloodstain patterns, correctly interpreting and applying them to casework. Combines and updates material from Blood Dynamics and Bloodstain Pattern Evidence into one comprehensive reference Covers new topics, including arterial damage pattern identification, staging of crime scenes, legal applications, and problems from both sides of the bench More than 300 full color photographs, some with line overlays showing the objective criteria which identify patterns

Bloodstain evidence has become a deciding factor in the outcome of many of the world's most notorious criminal cases. As a result, substantiation of this evidence is crucial to those on either side of the courtroom aisle. The challenge is to obtain an authoritative reference that provides the latest information in a comprehensive and effective manner. Principles of Bloodstain Pattern Analysis: Theory and Practice presents an in-depth investigation of this important subject matter. A multidisciplinary approach is presented throughout the book that uses scene and laboratory examinations in conjunction with forensic pathology, forensic serology, and chemical enhancement techniques. Emphasis is on a thought process based on taxonomic classification of bloodstains that takes into account their physical characteristics of size, shape, and distribution, and the specific mechanisms that produce them. Individual chapters analyze case studies, with two chapters specifically discussing the details of legal issues as they pertain to bloodstain pattern analysis. Information highlighted throughout the book includes an examination of bloodstained clothing and footwear and information on bloodstain interpretation for crime scene reconstruction. Dramatic color images of bloodletting injuries, bloodstains, and crime scenes are also presented to compliment the technical content of this resource. Features § Provides 500 full color photographs - the first bloodstain pattern book presenting dramatic full color images of bloodletting injuries, bloodstains, and crime scenes § Contains appendices with scientific data that includes trigonometric tables and metric equivalents, as well as crime scene and laboratory check lists, and biohazard safety precautions § Discloses court decisions relating to bloodstain pattern analysis and presumptive blood testing § Written by authors with many years of experience in the field, and features chapters contributed by qualified and respected forensic scientists and attorneys

Academic Paper from the year 2019 in the subject Chemistry - Analytical Chemistry, grade: A, , language: English, abstract: This text is focussing on the effectiveness of oxidizing reagents in removal of blood stains. Adjustments, amendments, and concealing of the crime evidence have resulted in an increment in the world’s crime rate. One such recurring hindrance can be seen with the most vital forms of evidence; bloodstains. Bloodstains are considered to be one of the most difficult stains to remove and even after cleaning them off the clothes through the detergents available in the market, there are some colored traces left which do not disappear completely and can be detected. Forensic scientists use luminol to detect bloodstains which when reacted with iron in blood stains exhibit chemiluminescence. This led to thinking of to what extent were these criminals able to manage the escape by washing the stains and hinder the evidence. After researching about the detergents from journals and websites like "The Science of Stain Removal, Study of Oxyper- H2O2, and Study of sodium perborate" and also studying the effect of various compounds present in them, it was found out that the active oxygen reagents were the sources through which bloodstain removal was possible. This helped in framing a research idea: To what extent does the change in mass of the oxidizing reagent, sodium perborate, sodium percarbonate and hydrogen peroxide found in detergents is effective in removing bloodstains, measured by spectrophotometric analysis of change in chemiluminescence intensity of luminol due to the oxidation of ferrous to ferric ions in stock solution containing oxidizing agents and iron solution imitating blood at room temperature (30°C)? In this essay, the correlation between the removal of the stains and the extent to which it depends on the amount of reagent was measured. The decrease in chemiluminescence signifies the extent to which the stains are removed. On this basis, the cleansing action of various oxidizing agents like hydrogen peroxide, sodium perborate, and sodium percarbonate was compared. Seeing the competence of the strongest oxidizing reagent, it can be considered that this research will be useful for forensic science departments to detect the extent to which evidence was tried to be concealed as all the oxidizing agents contain H2O2 and even after washing the clothes, some content of H2O2 is left. It will also be valuable for the detergent manufacturers because, through this research, they will opt for a better oxidizing agent to yield a better cleansing action.
