Available in PDF, EPUB and Kindle. Book excerpt: The range at which a weapon has been fired is an important measurement for the reconstruction of firearms offenses (murder, suicide, accident). All changes caused by a shot and which vary according to the distance from the weapon are suitable in principle for determining this distance. However, some procedures are very elegant in theory but hardly applicable in practice. The constructions of ammunition and the sequence of events during a shot are dealt with first as this knowledge forms a basis for understanding the various methods. \ The individual zones (classes) of firing distances (contact shot, intermediate shot, distance shot) are described. In this connection, the morphological methods for determining the firing distance are discussed. From the shape and size of the powder residue distribution (soot stains, powder tattooing) and with the knowledge of the weapon and ammunition, the distance from the target can be elucidated. In this chapter, the methods of making an invisible distribution visible are also dealt with. In order to determine the range of the shot from the appearance of the wound no complicated apparatus is necessary. One can judge with the naked eye. These procedures have a great advantage over the methods discussed in the following chapter in that they give stronger proof. They are more vivid and convincing for the uninitiated (judge or jury) than abstract measurements obtained by scientific devices.

Book excerpt: An improved method for firing distance determination on exhibits that cannot be processed in the laboratory such as cars, doors, windows, or furniture is described. The novel part of the method includes transfer of total nitrite (nitrite ions and smokeless powder residues) from the target to an adhesive lifter. After the transfer, vaporous lead and copper deposits around the bullet entrance hole are visualized on the target by sodium rhodizonate and rubeanic acid, respectively. The Modified Griess Test is carried out after alkaline hydrolysis of the smokeless powder residues on the adhesive lifter.
Download or read book Shooting Incident Reconstruction written by Michael G. Haag and published by Academic Press. This book was released on 2011-06-29 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shooting Incident Reconstruction, Second Edition, offers a thorough explanation of matters from simple to complex to help the reader understand the factors surrounding ballistics, trajectory, and shooting scenes. Forensic scientists, law enforcement, and crime scene investigators are often tasked with reconstruction of events based on crime scene evidence, along with 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. Written by the world's most well-respected shooting scene and ballistics experts, the book addresses the terminology, science, and factors involved in reconstructing shooting incident events to solve forensic cases. It covers 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; and the position of a victim at the moment of impact. The probable flight path of a projectile and the manner in which a firearm was discharged are also discussed. Case studies illustrate real-world application of technical concepts, supported by over 200 full-color diagrams and photographs. This book will be of value to practicing forensic scientists (firearm and toolmark examiners), ballistics experts, crime scene personnel, police departments, forensic consultants (generalists), attorneys and judges, medical examiners (coroners), and forensic pathologists. 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

Download or read book Wound Ballistics written by Beat P. Kneubuehl and published by Springer Nature. This book was released on 2022-08-11 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: The definitive interdisciplinary reference work for wound ballistics Basics The book begins by providing the necessary basic knowledge about physics, ballistics and ammunition and weapons. Then it describes the behaviour of projectiles in humans and animals (the physics of gunshot injuries) and introduces the experimental simulation of gunshot wounds, including the materials suitable for this purpose. Applications These basic principles can be applied in forensic medicine and criminalistics. The gunshot wound provides some forensic traces and the experimental reconstruction helps to understand the dynamic crime process. The wounding potential of non-lethal weapons can be determined. In emergency and war surgery, injuries caused by small arms bullets and fragments as well as by gas jets (of gas weapons) can be assessed. International conventions could be freed from undefined terms (such as “unnecessary suffering”) with the help of physical quantities. Reference work Detailed tables as e. g. ballistic data of numerous cartridge types, also older ones, material properties, as well as many otherwise difficult to access data and a trilingual glossary of ballistic and technical terms in the languages German, English and French. NEW Wound Ballistics of European Police ammunition References to recent research results Partly coloured illustrations Due to the increase in terrorist and criminal activities worldwide, it is not only members of the armed forces who are affected. Surgeons, forensic doctors, police officers and criminalists also need to know and be able to assess the specifics of gunshot wounds.
Download or read book Determination of Shooting Distance from Deformation of the Recovered Bullet written by ML. Fackler and published by . This book was released on 1987 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method is reported for estimating shooting distance by comparing the amount of bullet deformation of a recovered bullet with that produced in a series of test bullets fired into 10% ordnance gelatin at 4°C. Bullet deformation and fragmentation pattern in this gelatin was previously found to be comparable to that seen in living animal muscle. Striking velocities of the test bullets were lowered stepwise until a test bullet was produced with less deformity than the evidence bullet. Two shots were then made through the abdomen of a fresh swine cadaver at velocities approximating those of the last two test shots in gelatin. This served as verification of the gelatin's calibration against animal tissue and gave an additional set of bullets whose degrees of deformation bracketed that of the evidence bullet. Separate interpolations were done for bullet length, average bullet tip diameter, and bullet weight using both sets of bracketing test bullets. The resulting velocities were then converted to distances using the manufacturer's velocity tables. The average of the interpolations was 256 yds (234 m); all six fell within a range of 33 yds (30 m) (from 238 to 271 yds [218 to 248 m]).

Download or read book Shooting Trajectory Reconstruction Workbook written by N. Leroy Parker and published by AuthorHouse. This book was released on 2013-01-08 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Use of Image Analyzing Software for Muzzle to Target Distance Determination written by Kimberly A. Edwards and published by . This book was released on 2011 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Muzzle to target distance can be an important aspect in criminal investigations. For most distance determination opinions to be of value to an investigation, the range must be stated such that it gives meaningful information and the resulting bracket of muzzle to target distance must also be defended during courtroom testimony. Current measurement tools lead to subjective opinions by examiners. With objective measurements, examiners can provide improved investigative conclusions that may be defended in court with quantifiable data. Due to the rapid advancement in software technology in recent years, the ability exists to analyze targets with more accurate measurements. Currently, test targets are measured by approximate methods which utilize a high degree of subjectivity. This study examined the application of Image J, image analyzing software, for use in determining muzzle to target distance. This research examined objective data to include particulate density and Gunshot residue dispersion and carried out a statistical replicate study to determine the number of targets needed at a given distance for each gun and ammunition combination. One pistol, revolver, rifle and shotgun were selected for this study. Test targets were shot five times at distances of: 4, 8, 12, 16, 20, 24 and 28 inches for the pistol, revolver and rifle, and at distances of: 4, 8, 12 and 16 feet for the shotgun. Visual and chemical examinations were performed on test targets using standard protocol procedures, published through the National Institute of Justice (NIJ) Distance Determination Training Module (2011). The targets were digitally photographed through each step and analyzed using the aforementioned protocol and Image J, image analyzing software. Comparisons were made between the National Institute of Justice model and Image J. Data were obtained and reported using the image analyzing software for particulate count and GSR dispersion."--Abstract.
