“…Issues that a latent print examiner might face include only having a partial print to compare to the exemplars, or being given smudged and distorted prints to analyze (Saks and Faigman, 2008;Ulery et al, 2011). The latent prints could also overlap with other prints (Ulery et al, 2011), or be found on a surface where the difficulty of collection is greater (van Dam et al, 2016). It is also possible for a print to become distorted as it is made, influencing distances or angles between two traits on a latent print to misleadingly differ from an exemplar (National Research Council, 2009).…”

“…The potential variability of surface -porous, non-porous, coloured, etc. -has also been identified as an obstacle for past studies on error rates of latent print examiners, which have typically used latent prints placed under controlled conditions on an appropriate or lower-difficulty surface (van Dam et al, 2016). In addition to this, two prints from the same source can appear different due to environmental influences or factors such as pressure distortion (Thompson and Cole, 2007).…”

“…Latent print evidence has been used as a means of identification for almost a century and has played a major role in convictions across North America (van Dam et al, 2016;Cole, 2007). With efforts from policeman Edward Foster ), remembered as the "Father of Canadian Fingerprinting", an Order of Council was passed on July 21, 1910, authorizing the use of the first fingerprint system in Canada (Lee and Ramotowski, 2001).…”

“…Furthermore, the disadvantage of latent prints often being smudged or only partially formed presents challenges to latent print examiners in making comparisons (Kumar et al, 2015). During transport, it is possible for fingerprint evidence to be contaminated, lost, or damaged (van Dam et al, 2016). Additionally, cognitive bias from examiners could interfere with their judgement when making an analysis (Expert Working Group, 2012).…”

Fingerprint Identification: Potential Sources of Error and the Cause of Wrongful Convictions

Fingerprint identification has long been used by law enforcement to either identify or eliminate potential suspects in a case. It relies on friction ridges -the upraised skin that forms grooves on fingers -and friction ridge impressions, which form from natural secretions of sweat and other trace components. Latent prints, a common term for friction ridge impressions, have many benefits and advantages as a type of forensic evidence. However, they are not a perfect tool: wrongful convictions identified by post-conviction DNA testing and the re-evaluation of forensic evidence have spawned criticism and investigation into the scientific basis of this branch of forensics. This literature review examines literature in both the scientific and legal fields, and investigates three main themes: the principle of uniqueness assumed in individualization, the presence of cognitive bias and human error in analysis, and the changing role of expert testimony in court. There are arguments both for and against uniqueness, but it is still difficult to prove using statistical models and data analysis. Bias in examiners, on the other hand, undeniably exists in different ways, and should be actively guarded against in fingerprint analysis and expert testimony. Expert witness testimony that misleads, exaggerates, or is scientifically unsupportable has been linked to wrongful convictions in the past, highlighting the importance of careful regulation of how an expert witness is advised to testify. In addition to these topics, the techniques of collecting latent print evidence and the standard procedures of analysis have also been examined and evaluated for potential sources of error.Le maintien de l'ordre public utilise depuis longtemps les empreintes digitales pour identifier et éliminer des suspects d'une affaire criminelle. Les empreintes digitales se fient aux crêtes papillaires -les crêtes et les creux qui formes des rainures sur les doigts -et des empreintes des crêtes papillaires, ce qui se forme par les sécrétions naturelles de transpiration et autres composantes de traces. Les empreintes latentes, un terme courant pour les empreintes digitales, possèdent plusieurs avantages en tant qu'élément médico-légal de preuve. Toutefois, ce n'est pas une ressource fiable; des condamnations injustifiées identifiées par un test d'ADN post-condamnatoire et la réévaluation de l'évidence médico-légale ont frayé des critiques et des enquêtes de la base des sciences des empreintes digitales. Cette revue examine les textes dans les domaines scientifiques et médico-légaux, et examine trois thèmes : le principe d'unicité assumé par l'individualisation, la présence d'un biais cognitif et l'erreur humaine dans l'analyse, et le rôle changeant de témoignages experts devant la Cour. Il existe des arguments pour et contre l'unicité, mais l'unicité est tout de même difficile à prouver en utilisant les modèles statistiques et l'analyse de données. Un préjugé chez les examinateurs, d'autres parts, existe incontestablement, et devrait être activement...

“…KEYWORDS: forensic science, latent fingerprint detection, nile red, mesoporous silica nanoparticles, thermal papers, water submerged surfaces Fingerprint is one of the most important evidences in the scene of crime due to its usage for personal identification based on the fact that there is no one whose ridge patterns are identical to another (1). Therefore, technology for visualizing latent fingerprints is vital, especially for latent fingerprints deposited on the porous substrates, such as paper, fiber, and leather.…”

Evaluation of Nile Red‐Loaded Mesoporous Silica Nanoparticles for Developing Water‐Soaked Fingerprints on Thermal Paper

Nile red has been an alternative reagent for detecting latent fingerprints on wetted substrates. However, the presence of methanol in nile red solution could make injury to handlers and destroy the traces on surfaces, such as texts on thermal papers. A novel small particle reagent formulation constituting of mesoporous silica nanoparticles (MSNs) based on nile red was prepared to overcome the problem. Compared with the conventional reagents Oil Red O or nile red solution, the nile red‐loaded MSNs are highly selective to lipid residues of fingerprints and showed a greater ability to develop clear, sharp, and detailed fingerprints on thermal papers after these were immersed in water. In addition, it can retain texts on the thermal papers well and use only water as a solvent. These suggested that nile red‐loaded MSNs are a safe, efficient, and convenient method to develop latent fingerprints on wide range of substrates of forensic importance.

Towards Fingermark Dating: A Raman Spectroscopy Proof‐of‐Concept Study

et al. 2017

Fingermarks have, for a long time, been vital in the forensic community for the identification of individuals, and a possibility to non‐destructively date the fingermarks would of course be beneficial. Raman spectroscopy is, herein, evaluated for the purpose of estimating the age of fingermarks deposits. Well‐resolved spectra were non‐destructively acquired to reveal spectral uniqueness, resembling those of epidermis, and several molecular markers were identified that showed different decay kinetics: carotenoids > squalene > unsaturated fatty acids > proteins. The degradation rates were accelerated, less pronounced for proteins, when samples were stored under ambient light conditions, likely owing to photo‐oxidation. It is hypothesized that fibrous proteins are present and that oxidation of amino acid side chains can be observed both through Raman and fluorescence spectroscopy. Clearly, Raman spectroscopy is a useful technique to non‐destructively study the aging processes of fingermarks.
