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.

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

Crime scene investigation involves the use and integration of scientific methods, physical evidence, and deductive reasoning in order to determine and establish the series of events surrounding a crime. The quality of the immediate crime scene response and the manner in which the crime scene is examined are critical to the success of the investigation. Evidence that is missed or corrupted by incomplete or improper handling can have a devastating effect on a case and keep justice from being served. The Practice of Crime Scene Investigation covers numerous aspects of crime scene investigation, including the latest in education and training, quality systems accreditation, quality assurance, and the application of specialist scientific disciplines to crime. The book discusses a range of basic and advanced techniques such as fingerprinting, dealing with trauma victims, photofit technology, the role of the pathologist and ballistic expert, and signal processing. It also reviews specialist crime scene examinations including clandestine laboratories, drug operations, arson, and explosives.

This workbook is designed to assist the Crime Scene Analyst, Technician or Investigator in documenting bloodstained patterns that are located at the crime scene or on bloodstained items that are submitted for an analysis. It is also designed to assist the Crime Scene Analyst, Technician or Investigator in reconstructing or analyzing a bloodstained crime scene or a bloodstained item for which a bloodstain pattern analysis is requested The documentation could be accomplished with overall, midrange photographs and close-up photographs with 2, 3 or 6 centimeter stick-on tapes that should be placed in the center of each rectangular area. The documentation should also consist of notes and rough sketches with measurements. The close-up photographs of the rectangular areas with the 2, 3 or 6 inches stick-on tapes that were placed in the center of those areas should be taken with a parallel film /camera plane. The stick-on tapes should be labeled according to the surface on which they would be placed. Example: West wall of living room #1 (ww of lr #1) and west wall of living room #2 (ww of lr #2) etc. The number of close-up photographs would be determined by the number of rectangular areas with the stick-on tapes. Example: At least ten (10) close-up photographs should be taken if ten (10) stick-on tapes were placed on the bloodstained surface. The bloodstain pattern reconstruction or analysis should be done by first recognizing and or identifying the many different types of patterns in a bloodstained scene or on a bloody item. The next step should involve the reconstruction of the points or areas of convergence and origin and then a determination of how the other patterns were most likely created. The workbook contains several tasks and assignments that would provide the student with the tools to accomplish the documentation and analysis. The Crime Scene Analyst, Technician or Investigator after successfully completing the workbook / workshop should be aware that: 1.0 Single drops of blood in a crime scene or on an item were influenced by the surface from which the blood fell (the volume); the diameter, the shape, the impact angle, the scalloping of the perimeter and the direction of travel of the dropped blood that impacted the target surface (the volume, the height from which the blood fell, the texture of the target surface on which the blood fell, the angle of the targeted bloodstained surface and the horizontal speed of the source that issued the blood). 2.0 Numerous drops of blood in the same pattern in a crime scene or on an item were influenced by the force or the impact (less than 25 feet per second – dropped blood and cast-off bloodstain); (25 to 100 feet per second – medium velocity bloodstain); (over 100 feet per second – high velocity bloodstain); projected blood (arterial bleeding); transfer of blood from one object to another (contact or transfer bloodstains, imprint bloodstains, smears or swipes and wipes); large volumes of blood (splashed or pooled blood) 3.0 The reconstruction or analysis of the points or areas of origin could be determined by strings, scaled drawings or calculations. The interpretation of the other patterns (non impact) along with the Medical Examiner’s autopsy report should allow the crime scene analyst, technician or Investigator to complete a bloodstain pattern analysis report and if possible explain and or testify to the sequence of events that occurred at the crime scene.

This specially developed workbook can be used in conjunction with the Complete Crime Scene Investigation Handbook (ISBN: 978-1-4987-0144-0) in group training environments, or for individuals looking for independent, step-by-step self-study guide. It presents an abridged version of the Handbook, supplying both students and professionals with the most critical points and extensive hands-on exercises for skill enhancement. Filled with more than 350 full-color images, the Complete Crime Scene Investigation Workbook walks readers through self-tests and exercises they can perform to practice and improve their documentation, collection, and processing techniques. Most experienced crime scene investigators will tell you that it is virtually impossible to be an expert in every aspect of crime scene investigations. If you begin to "specialize" too soon, you risk not becoming a well-rounded crime scene investigator. Establishing a complete foundation to the topic, the exercises in this workbook reinforce the concepts presented in the Handbook with a practical, real-world application. As a crime scene investigator, reports need to be more descriptive than they are at the patrol officer level. This workbook provides a range of scenarios around which to coordinate multiple exercises and lab examples, and space is provided to write descriptions of observations. The book also supplies step-by-step, fully illustrative photographs of crime scene procedures, protocols, and evidence collection and testing techniques. This lab exercise workbook is ideal for use in conjunction with the Handbook, both in group training settings, as well as a stand-alone workbook for individuals looking for hands-on self-study. It is a must-have resource for crime scene technicians, investigators, and professionals who want a complete manual of crime scene collection and processing techniques.
