Several forensic sciences, especially of the pattern-matching kind, are increasingly seen to lack the scientific foundation needed to justify continuing admission as trial evidence. Indeed, several have been abolished in the recent past. A likely next candidate for elimination is bitemark identification. A number of DNA exonerations have occurred in recent years for individuals convicted based ...
In forensic science, soil, dust, and vegetable traces have as high a value as evidence as classical traces such as fingerprints or toolmarks. It is imperative that the potential information in these traces can be identified by a combination of analytical methods selected by a qualified expert. Experience has shown that the best results can be expected when all of the aspects of evidence, includ...
A model that is based on the knowledge of experienced investigators in the analysis of serial crime is suggested to bridge a gap between technology and methodology. Its purpose is to provide a solid methodology for the analysis of serial crimes that supports decision making in the deployment of resources, either by guiding proactive policing operations or helping the investigative process. Form...
The science in forensic science has received increased scrutiny in recent years, but interest in how forensic science is managed is a relatively new line of research. This paper summarizes the literature in forensic science management generally from 2009 to 2013, with some recent additions, to provide an overview of the growth of topics, results, and improvements in the management of forensic s...
To improve inferences about psychological and social evidence contained in pictures and texts, a five-step algorithm-Systematic Analysis (SA)-was devised. It combines basic principles of interpretation in forensic science, providing a comprehensive record of signs of evidence. Criminal justice professionals evaluated the usefulness of SA. Effects of applying SA were tested experimentally with 4...
Certification is the process by which individual practitioners of a profession are deemed competent, by a peer review process, to practice that profession. Criminalistics is a rather young profession, and until the recent publicity occasioned by a myriad of television dramas and documentaries, a rather obscure one. There has been little oversight of the profession and little call for such overs...
I express my gratitude to the Royal Society. It has played a key role in bringing together scientists and others interested in forensic science. By hosting the conference ‘The paradigm shift for UK Forensic Science’ it has provided a true forum to share developments and engage in discussion. I wish to pay particular tribute to Professors Sue Black and Niamh Nic Daeid for their vision, their org...
The presence of smeared or unsmeared ink on the skin resulting from the writing process has been observed in a number of suicide victims who have left suicide notes. The authors report a case of a palmar "cutaneous ink sign" and discuss its forensic science import.
This paper provides a review of recent investigations on the image processing techniques used to match spent bullets and cartridge cases. It is also, to a lesser extent, a review of the statistical methods that are used to judge the uniqueness of fired bullets and spent cartridge cases. We review 2D and 3D imaging techniques as well as many of the algorithms used to match these images. We also ...
