Book excerpt: This book provides a line of communication between academia and end users/practitioners to advance forensic science and boost its contribution to criminal investigations and court cases. By covering the state of the art of promising technologies for the analysis of trace evidence using a controlled vocabulary, this book targets the forensics community as well as, crucially, informing the end users on novel and potential forensic opportunities for the fight against crime. By reporting end users commentaries at the end of each chapter, the relevant academic community is provided with clear indications on where to direct further technological developments in order to meet the law requirements for operational deployment, as well as the specific needs of the end users. Promising chemistry based technologies and analytical techniques as well as techniques that have already shown to various degrees an operational character are covered. The majority of the techniques covered have imaging capabilities, that is the ability to visualize the distribution of the target molecules within the trace evidence recovered. This feature enhances intelligibility of the information making it also accessible to a lay audience such as that typically found with a court jury. Trace evidence discussed in this book include fingermarks, bodily fluids, hair, gunshot residues, soil, ink and questioned documents thus covering a wide range of possible evidence recovered at crime scenes.

Book Synopsis Scanning Electron Microscopy and X-Ray Microanalysis by : Joseph Goldstein
Download or read book Scanning Electron Microscopy and X-Ray Microanalysis written by Joseph Goldstein and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 679 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has evolved by processes of selection and expansion from its predecessor, Practical Scanning Electron Microscopy (PSEM), published by Plenum Press in 1975. The interaction of the authors with students at the Short Course on Scanning Electron Microscopy and X-Ray Microanalysis held annually at Lehigh University has helped greatly in developing this textbook. The material has been chosen to provide a student with a general introduction to the techniques of scanning electron microscopy and x-ray microanalysis suitable for application in such fields as biology, geology, solid state physics, and materials science. Following the format of PSEM, this book gives the student a basic knowledge of (1) the user-controlled functions of the electron optics of the scanning electron microscope and electron microprobe, (2) the characteristics of electron-beam-sample inter actions, (3) image formation and interpretation, (4) x-ray spectrometry, and (5) quantitative x-ray microanalysis. Each of these topics has been updated and in most cases expanded over the material presented in PSEM in order to give the reader sufficient coverage to understand these topics and apply the information in the laboratory. Throughout the text, we have attempted to emphasize practical aspects of the techniques, describing those instru ment parameters which the microscopist can and must manipulate to obtain optimum information from the specimen. Certain areas in particular have been expanded in response to their increasing importance in the SEM field. Thus energy-dispersive x-ray spectrometry, which has undergone a tremendous surge in growth, is treated in substantial detail.
Book Synopsis On the Integrated Analysis and Forensic Interpretation of Gunshot Residues by : Callum Bonnar
Download or read book On the Integrated Analysis and Forensic Interpretation of Gunshot Residues written by Callum Bonnar and published by . This book was released on 2023 with total page 0 pages. 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.
