Download or read book Shooting Incident Reconstruction written by Michael G. Haag and published by Academic Press. This book was released on 2020-10-10 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. 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. New chapters on special reconstructive properties and value of shootings involving sub-machine guns or pseudo automatic firearms, rate of fire with special attention on shot-to-shot time intervals, human factors in shooting incidents Updated and revised glossary terms to fit with new technology and the emergence of standardization of terms by groups such as the Organization of Scientific Advisory Committees Provides clear practice standards and ethical guidelines for those involved in reconstructing shooting scenes

Available in PDF, EPUB and Kindle. Book excerpt: Gunshot residue (GSR) is a type of trace material that can be very important to the investigative, coronial, or criminal justice outcomes of incidents involving firearms. If scientists can identify and interpret these traces, they can contribute valuable information to the forensic process. The intent of this body of work was to improve the capabilities available to forensic practitioners, regarding this particular category of trace evidence. -- Specifically, it was identified that contemporary GSR analyses largely target the inorganic portion of gunshot residues (IGSR). Forensic scientists already recognize that firearms also produce organic residues (OGSR). Research into the exploitation of OGSR traces as evidence has been well documented in academic literature, but as yet no single technique has been adopted into routine laboratory use. It is even rarer for an integrated (IGSR/OGSR) methodology, using data on both components of the trace, to be used forensically for either detection or evaluation of traces. The original contribution to knowledge made by this PhD project was the exploration of options for this unified approach. -- New data on the subject were generated using combinations of laboratory experimentation, firing range fieldwork, and collection of survey samples. Authentic GSR samples were collected both from shooting experiments performed under controlled conditions and also following “natural” shooting activities undertaken by recreational shooters. It was found that liquid chromatography-mass spectrometry instrumentation, already available to forensic chemistry laboratories, could detect known OGSR compounds from recovered traces. A process for preparing subsamples for this organic analysis, while still retaining the possibility of inorganic analysis by scanning electron microscopy (SEM-EDS), was developed. Further samples were collected alongside written surveys asking about recent firearm use. Analysis of the pool of “non-shooter” background samples gave confidence that the combination of analytical methods was specific for the detection of GSR, with few to no false positives. This tandem approach offers potential improvement over current methodologies, as it increases the mass of material that can be targeted for detection. It also allows greater confidence when discriminating between GSR and inorganic, environmental GSR-like interferences by providing more chemical data to the analyst from each trace. These data are applicable to sub-source and activity-level evaluations used by experts in some jurisdictions when presenting their findings. -- Next, different strategies for combining the outputs of each test into a single reportable result were investigated. Initially, the inorganic and organic laboratory tests were judged to indicate whether samples were either “positive” or “negative” for GSR using separate, predetermined categorical requirements. A Bayesian updating approach was then used to show that a statistical improvement in diagnostic accuracy was achieved when using two categorical tests in tandem. More advanced statistical methods including both univariate and multivariate models were also used to generate likelihood ratios representing the potential strength of evidence that could be provided to an investigator or courtroom. Of several techniques evaluated, artificial neural networks were chosen as the preferred method for synthesising multivariate data into a cohesive output without needing to discard any underlying information. Some perceived advantages and disadvantages of choosing categorical or likelihood ratio-based reporting are discussed. Data were also used as examples to perform certain sub-source and activity-level evaluations. -- Finally, two separate spectrometers featuring ambient-ionisation capability were assessed for possible use as rapid and selective detectors for analysing GSR. Both “Direct Sample Analysis” (DSATM) and “Direct Analysis in Real-Time” (DART®) ion-sources were found to be capable of desorbing and ionising relevant OGSR compounds. Either instrument was suitable for analysing, and potentially discriminating between, smokeless powders collected in their unburned state. However, the outcomes for GSR samples collected using adhesive stubs were poor due to a significant background signal arising from the adhesive in the stubs themselves. Therefore it is suggested that any future efforts to incorporate AIMS into a GSR detection procedure should focus on sample collection or isolation procedures. -- In summary, the integrated analysis of GSR traces was found by the author to both be technically feasible and to offer greater value to forensic scientists than the sum of its parts.

Available in PDF, EPUB and Kindle. Book excerpt: Firearms evidence examination and fingerprint comparison have had a long and interesting history. The role of fingerprints in human identification can actually be traced back several thousand years. The development of the science of fingerprint comparison and the scientific examination of firearms, however, began in the early 19th century. The goal of the preservation of physical evidence is to associate each piece of evidence with its responsible source, allowing forensic scientists to answer questions regarding the who, what, when, where, how, and why of a crime. Firearms and Fingerprints, Revised Edition traces these early beginnings and the icons that laid the groundwork for the current science. Coverage includes the highly specialized education, training, and experience required for current practitioners in the modern forensic laboratory. Providing a thorough examination of the capabilities and limitations of firearms and latent print evidence, this eBook also looks at future possibilities as these fields continue to evolve and looks at the recent legal challenges that have arisen. Author Edward Hueske uses his extensive experience as a forensic scientist, professor, and consultant to paint a detailed picture of this fascinating science, which is sure to engage students.
