Workbook On Crime Scene Reconstruction Of Shooting Incidents

This workbook is designed to help the Crime Scene Analyst, Technician or Investigator in documenting the bullet holes and or indentations present at the crime scene, find the vertical and horizontal impact angles and determine the location of the muzzle of the weapon at the time of the shooting.

This workbook is designed to assist the Crime Scene Analyst, Technician or Investigator in documenting any bullet holes and or indentations that may be present at the crime scene. This documentation could be accomplished with overall, midrange and close-up photographs, rough sketches with the required measurement and notes. The workbook is also designed to assist the Crime Scene Analyst, Technician or Investigator in understanding the different ways of determining: a. The upward (inclined) or downward (sloped) bullet impact angles to the horizontal plane and the horizontal bullet impact angles, to the left or right when facing the surface with the bullet hole, that would be needed to reconstruct the shooting incident. b. The approximate location(s) of the muzzle of the gun at the time of the shooting. The determined or calculated bullet impact angle(s) to the horizontal plane could be used by the Crime Scene Analyst, Technician or Investigator to determine the horizontal distance(s) below the path of the bullet and the distance(s) the bullet(s) traveled from the muzzle of the gun to the hole(s) in the victim or object. These distances could then be used to determine / calculate the location of the shooter for any known or assumed muzzle height(s) based on the orientation of the shooter. Also, having the horizontal bullet impact angle the Crime Scene Analyst, Technician or Investigator could determine the perpendicular horizontal distance(s) from the muzzle of the gun to the surface with the bullet hole(s) and or indentation(s). A trajectory or shooting reconstruction could be accomplished by the utilization of one or more of the following methods. The emphasis of this workbook would be on the reconstruction of crime scene shooting incidents utilizing these methods: Strings and dowels rods Scaled drawings Calculations using the trigonometric ratios Computers programs The workbook would also provide the Crime Scene Analyst, Technician or Investigator with an opportunity to reconstruct and review fifteen real cases. More emphasis was placed on solution of these cases (which are located in the back of the book) by calculations using the trigonometric ratios and the Pythagorean Theorem since this method could be utilized to verify the accuracy of the other methods. Potentially, very valuable investigative information could be developed through a trajectory or shooting reconstruction of the crime scene that would assist the Analyst, Technician or Investigator when interviewing a subject to determine if he or she is truthful in the sequence of events or the manner in which the incident took place. Specific information may be logically inferred if the Crime Scene Analyst, Technician or Investigator is knowledgeable about trajectory or shooting reconstruction.

Forensic scientists, law enforcement, and crime scene investigators are often tasked with reconstruction of events based on crime scene evidence, and the subsequent analysis of that evidence. The use and misuse of firearms to perpetrate crimes from theft to murder necessitates numerous invitations to reconstruct shooting incidents. The discharge of firearms and the behavior of projectiles create many forms of physical evidence that, through proper testing and interpretation by a skilled forensic scientist, can establish what did and what did not occur. This book is generated from the authors' numerous years of conducting courses and seminars on the subject of shooting incident reconstruction. It seeks to thoroughly address matters from simple to complex in providing the reader an explanation of the factors surrounding ballistics, trajectory, and shooting scenes. The ultimate objectives of this unique book are to assist investigators, crime scene analysts, pathologists, ballistics experts, and lawyers to understand the terminology, science, and factors involved in reconstructing shooting incident events to solve forensic cases. The book will cover the full range of related topics including the range from which a firearm was discharged, the sequence of shots in a multiple discharge shooting incident, the position of a firearm at the moment of discharge, the position of a victim at the moment of impact, the probable flight path of a projectile, the manner in which a firearm was discharged and much more. Written by the most well-respected shooting scene and ballistics experts in the world Contains over 200 full-color diagrams and photographs that support and illustrate key concepts Case studies illustrate real-world application of technical concepts

The ultimate goal of collecting, preserving, and examining physical evidence is individualization - associating each piece with its responsible source. Firearms evidence in particular has the potential to individualize its source. Accessible and comprehensive, Practical Analysis and Reconstruction of Shooting Incidents provides the foundation necessary to develop and sharpen the skills used to investigate shooting incidents. It provides an explanation of what constitutes pertinent evidence and appropriate results pertaining to autopsies, forensic laboratory analysis, and reenactments. The text also reviews basic firearm design, function, ammunition components, and the terminology required for understanding evidence encountered at the scene. The book explains the basic mathematics of shooting reconstruction and includes sample problems at the end of each chapter. It presents case studies that feature those involving the John F. Kennedy and Robert F. Kennedy assassinations. It also details proper photographic documentation and effective courtroom techniques used to present the results of shooting reconstructions to juries, with examples of acceptable demonstrative evidence. Arming the investigator with the means to successfully examine and evaluate what transpired at the scene, Practical Analysis and Reconstruction of Shooting Incidents is an important resource to have accessible at all times.

Shooting Incident Reconstruction, Third Edition, offers a thorough explanation of matters from simple to complex to help the reader understand the factors surrounding ballistics, trajectory, and shooting scenes.
