Book excerpt: An earlier companion paper to the present one dealt with a literature review as well as blood droplet formation and impacts to stationary target surfaces. The present paper discusses the results of experiments with moving target surfaces. These are discussed in the context of their correlation with blood droplet impacts to inclined stationary targets and with respect to the interpretation of bloodstain patterns at crime scenes where the target surface is capable of its own movement. A special belt device was designed and constructed for the experiments reported here. This motorized apparatus was used to drive paper belt target surfaces at various controlled speeds.

Book excerpt: The interpretation of bloodstain patterns at crime scenes has received increased attention in recent years. Important to an understanding of this is knowledge of the fundamentals of blood droplet formation and impact dynamics. A review of the literature reveals that a considerable amount of work has been done with aqueous drop dynamics. Workers in the forensic science area seem to have been unaware of this. In addition, some of the most important and comprehensive early work with blood droplet dynamics seems to have been forgotten. It is not cited in more recent publications dealing with bloodstain pattern interpretation. This literature is reviewed and discussed as well. The present study presents results of experiments with blood droplet dynamics and high-speed photographs of blood droplet impacts on stationary target surfaces. Some longstanding misconceptions of importance to forensic scientists engaged in crime scene reconstruction are discussed.
Download or read book Blood Dynamics written by Anita Y. Wonder and published by Academic Press. This book was released on 2001 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today's resources on bloodstain analysis are still based on methods that were derived in the 1920s. Although medical and clinical research have provided a growing body of information on blood composition and behavior, this information has been ignored in favor of historical bloodstain analysis methods-until now. With 25 years of experience in the field, author Anita Wonder shows how to use these new methods for interpreting bloodstains, including non-Newtonian fluid behavior (a process that does not conform to Sir Isaac Newton's laws of motion) and three-dimensional dispersion modeling. Blood Dynamics focuses on how to accurately identify eight bloodstain pattern types and their permutations. It covers every aspect of bloodstain analysis, and shows how some standard practices of reconstruction are not only unnecessary for identification of blood dynamics, but can even be misleading. This book presents completely new scientific evaluations of blood dynamics and will fundamentally change the way in which bloodstains are interpreted. As such, it will be required reading for anyone who deals with blood evidence at the crime scene, in the lab, or in the courtroom.

Download or read book Blood Traces written by Peter R. De Forest and published by John Wiley & Sons. This book was released on 2021-08-06 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: A guide to the scientific interpretation of blood traces Blood Traces provides an authoritative resource that reviews many of the aspects of the interpretation of blood traces that have not been treated with the thoroughness they deserve. With strict adherence to the scientific method, the authors — noted experts on the topic — address the complexities encountered when interpreting blood trace configurations. The book provides an understanding of the scientific basis for the use of blood trace deposits, i.e. bloodstain patterns, at crime scenes to better reconstruct a criminal event. The authors define eight overarching principles for the comprehensive analysis and interpretation of blood trace configurations. Three of these principles are: blood traces may reveal a great deal of useful information; extensive blood traces, although present, may not always yield information relevant to questions that may arise in a given case; and a collection of a few seemingly related dried blood droplet deposits is not necessarily an interpretable “pattern”. This important resource: Provides the fundamental principles for the scientific examination and understanding of blood trace deposits and configurations Dispels commonly accepted misinformation about blood traces. Contains a variety of illustrative case examples which will aid in demonstrating the concepts discussed Written for forensic scientists, crime scene investigators, members of the legal community, and students in these fields, Blood Traces presents the fundamental principles for the scientific examination of blood trace deposits and configurations.

Download or read book Blood Powder and Residue written by Beth A. Bechky and published by Princeton University Press. This book was released on 2021-01-19 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: A rare behind-the-scenes look at the work of forensic scientists The findings of forensic science—from DNA profiles and chemical identifications of illegal drugs to comparisons of bullets, fingerprints, and shoeprints—are widely used in police investigations and courtroom proceedings. While we recognize the significance of this evidence for criminal justice, the actual work of forensic scientists is rarely examined and largely misunderstood. Blood, Powder, and Residue goes inside a metropolitan crime laboratory to shed light on the complex social forces that underlie the analysis of forensic evidence. Drawing on eighteen months of rigorous fieldwork in a crime lab of a major metro area, Beth Bechky tells the stories of the forensic scientists who struggle to deliver unbiased science while under intense pressure from adversarial lawyers, escalating standards of evidence, and critical public scrutiny. Bechky brings to life the daily challenges these scientists face, from the painstaking screening and testing of evidence to making communal decisions about writing up the lab report, all while worrying about attorneys asking them uninformed questions in court. She shows how the work of forensic scientists is fraught with the tensions of serving justice—constantly having to anticipate the expectations of the world of law and the assumptions of the public—while also staying true to their scientific ideals. Blood, Powder, and Residue offers a vivid and sometimes harrowing picture of the lives of highly trained experts tasked with translating their knowledge for others who depend on it to deliver justice.
