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.

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.

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

As witnessed in landmark criminal cases, the quality and integrity of bloodstain evidence can be a crucial factor in determining a verdict.

The work of a crime scene investigator requires stellar organizational skills and razor-sharp attention to detail. Developing these skills is best achieved through hands-on training simulating actual case events. Crime Scene Processing and Investigation Workbook takes students from the classroom to the field and into the lab to explore a range of scenarios they will likely encounter on the job. Exercises presented in this practical handbook include assessing the scene, crime scene photography and mapping, fingerprint evidence, documentation, impression-casting, bloodstain pattern recognition, and advanced techniques for scene processing. The book also examines the actions of the initial responding officer, highlights special scene considerations, and describes the role of crime scene analysis and reconstruction. Designed to complement Gardner’s Practical Crime Scene Processing and Investigation, this manual uses a consistent format throughout to ensure assimilation. Each chapter begins with a list of key terms and provides learning outcomes that describe the goal of the chapter. Tasks are then broken down into specific segments, with objectives, necessary materials, and a concept overview provided to promote heightened focus on salient points in the chapter. Post-lab questions enable students to test their grasp of the material and sample worksheets are provided that can be duplicated and used in actual case scenarios. By practicing the techniques described in this manual, students will be ready when they encounter them for the first time on the job.

This book addresses every aspect of the analysis and reconstruction of the events surrounding a crime. Beginning with established protocols for crime scene processing, the authors outline their unique methodology for event analysis. This technique defines specific actions, discusses the order of those actions, and offers significant insight into determining what did or did not happen in the course of the incident under investigation. Using case studies and more than 200 color photos, the book demonstrates how the method can be used to explain clues that would otherwise be puzzling or ambiguous.

This book introduces the core concepts of bloodstain pattern analysis that help to understand and make independent contributions to crime scenes accurately. It presents a bridge between new research results and the practical work field of crime scene investigation in bloodstain pattern analysis, by showing and detailing reports of two different scenarios. The scenarios presented have an extensive description of gathered evidence and are diversified with real crime scene photography and sketches. This kind of case report is rare in scientific books, but the author, as a researcher, has permission from the authorities to present the cases. The book finally concludes with the main problems of modern bloodstain pattern analysis and discusses the way forward.
