EBOOK SYNOPSIS:

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

EBOOK SYNOPSIS:

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

 What Are The Features Of A Bloodstain Pattern

Available Language: English, Spanish, And French
EBOOK SYNOPSIS:

The discipline of Bloodstain Pattern Analysis (BPA) is founded on the visual evaluation of the diagnostic properties of bloodstain patterns and an interpretation of the mechanistic cause(s) leading up to their deposition at scenes of violent crime. The lack of objective bloodstain pattern measures and the often subjective opinions of bloodstain pattern analysts are among some of the main criticisms of the discipline. It is also argued, that the process of characterising the main properties of a bloodstain pattern is tantamount to assigning a cause to the bloodstain pattern. These persisting issues reflect the dire need for an established and discipline-standard BPA methodology. In light of this, an argument exists for the development of a completely new method of bloodstain pattern characterisation, that is based on objective and measurable pattern features. In this thesis, it is proposed that leveraging on technology could potentially assist with the development of specific solutions to problems associated with the interpretation of bloodstain patterns. To that end, the role of digital image-processing, eye tracking technology and pattern recognition were each considered in three important areas of bloodstain pattern characterisation. These areas were: data collection, understanding the mindset of the BPA analyst and the development of an automated bloodstain pattern recognition system. One of the major outcomes of this research, and an original contribution to the discipline, is the validation of an automated system capable of distinguishing bloodstain patterns. This system is fundamentally reliant on the extraction of bloodstain pattern features. Upto now, this has remained a process confined to the opinions and subjective experience of a bloodstain pattern analyst. These features, based on common spatter bloodstain pattern properties, were extracted using a comprehensive image-processing methodology. It is noteworthy to mention that this thesis provides a unique insight into the mindset of the bloodstain pattern analyst. To do this, eye tracking technology was used to capture the viewing behaviour of BPA analysts during a pattern classification task. The eye tracking study demonstrated that BPA analysts tend to focus greater attention on distinct regions of a bloodstain pattern. It is shown that these regions may reflect properties that are crucial in forming a pattern classification. An understanding of the properties as they related to these diagnostic regions formed an important outcome of this study. Overall, this research exposes the immense possibilities that technology could contribute to improving objectivity and consistency in the discipline.

ISBN:
Available Language: English, Spanish, And French
EBOOK SYNOPSIS:

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.

EBOOK SYNOPSIS:

Graphical abstract: Highlights: A method for sequencing overlapping blood stains is proposed. Characteristic visual features are indicative for deposition sequence of transfer and drip stains. Expert decisions improve with knowledge about visual characteristics and their occurrence rates. Abstract: The deposition sequence of overlapping bloodstain patterns can be valuable reconstructive information. A formal method for sequencing overlapping bloodstain patterns has yet to be published. We present a method for sequencing overlapping transfer and drip stains using visual characteristics. A survey was held amongst educated bloodstain pattern analysts to determine whether the newly acquired method will assist them in correctly sequencing these overlapping bloodstain patterns. Results showed a significant improvement of expert decisions: the percentage of overlapping stains correctly sequenced by participants increased from 57 to 79% using the visual characteristics defined in this study. These results suggest that a decision support system can be built, which helps investigators at the crime scene to sequence overlapping bloodstain patterns.
