Objective establishment of the truth is the goal of any good crime scene investigator. This demands a consideration of all evidence available using proven scientific methodologies to establish objective snapshots of the crime. The majority of forensic disciplines shed light on thewho of a crime, bloodstain pattern analysis is one of the most imp
Mr. MacDonnell's object in writing Flight Characteristics and Stain Patterns of Human Blood was to advance the state of the art in an area of forensic science that has been neglected. The author states that the guides are just suggestions and not firm rules and will rarely be conclusive in and of themselves. The research was initiated because of the author's belief that there is a deficiency in documented knowledge regarding bloodstain evidence. Literature searched by the author contained little beyond elementary rules for establishing the direction of travel or simple correlations of a general character as a function of the distance a drop falls. The literature search included Dr. Kirk's text on Crime Investigation. However, the author states that the most comprehensive source of accurate information on this subject to date is the 1955 affidavit of the late Dr. Paul Kirk regarding his investigation of the Dr. Samuel Sheppard murder case. Mr. MacDonnell often refers to Dr. Kirk and states that in all instances the current investigation has verified both the accuracy and conclusions of Dr. Kirk's earlier work.
As witnessed in landmark criminal cases, the quality and integrity of bloodstain evidence can be a crucial factor in determining a verdict. Since the first edition of Interpretation of Bloodstain Evidence at Crime Scenes was published nearly a decade ago, bloodstain pattern interpretation has continued to grow as a branch of forensic science. Revised and updated to reflect new technology and developments in the field, the second edition is packed with new information and illustrations-including 421 photographs and diagrams of improved quality that will aid in interpretation of evidence. Expanding on a single chapter presented in the bestselling first edition, the second edition details, in four chapters, an introduction to bloodstain interpretation; low-velocity impact and angular considerations; medium and high-velocity impact; and the significance of partially dried, clotted, aged, and physically altered bloodstains in four new chapters. A full chapter on the detection of blood with luminol, featuring high-quality, full-color photographs of luminol reactions, has been added. This new edition also includes 12 new case studies in addition to 8 original case studies from the first edition that have been retained for their interpretative value. Everyone involved in crime scene evaluation and interpretation-law enforcement officers, criminologists, medical examiners, forensic pathologists, medicolegal personnel, and prosecutors and defense attorneys-will benefit from the improved and expanded second edition of this definitive reference.
Since 1955 when Dr. Paul Kirk first presented a bloodstain evidence affidavit in State of Ohio v. Samuel Sheppard, expert testimony on bloodstain interpretation has gained wide acceptance in U.S. courts. Scientific and Legal Applications of Bloodstain Pattern Interpretation brings together some of the most respected and noted experts in forensic science, the law, and bloodstain interpretation to provide a comprehensive overview of the discipline. It discusses research, applications, and the current view of bloodstain pattern interpretation within the legal system at the trial and appellate court levels, as well as scientific approaches and developments in the field. Scientific and Legal Applications of Bloodstain Pattern Interpretation will help attorneys who are questioning and cross-examining expert witnesses have a good working knowledge of bloodstain interpretation. Included is a full-color atlas of bloodstains, in conjunction with a glossary of terms and an outline of basic laboratory experiments that are commonly used in the discipline. Among the outstanding contributions in this volume you will find: An excellent chapter by Carol Henderson discusses the legal and ethical aspects of bloodstain pattern evidence in detail. A post-conviction analysis by Marie Elena Saccoccio evaluates how bloodstain evidence can play a role in the appeal process. Misinterpretation and overinterpretation of bloodstain evidence can occur in our courts of law-be prepared to effectively analyze the evidence and the testimony with Scientific and Legal Applications of Bloodstain Pattern Interpretation.
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.
Bloodstain pattern analysis helps establish events associated with violent crimes. It is a critical bridge between forensics and the definition of a precise crime reconstruction. The second edition of this bestselling book is thoroughly updated to employ recent protocols, including the application of scientific method, the use of flow charts, and the inter-relationship of crime scene analysis to criminal profiling. It provides more illustrations, including color photographs, and explains the use of computer programs to create demonstrative evidence for court.
