Abstract This article presents the position of the Document Section of the Canadian Society of Forensic Science (CSFS) regarding the use of an evaluation and reporting scheme often referred to as “the logical approach to evidence evaluation.” The section’s position is the logical approach to evidence evaluation and reporting, and is an appropriate and effective option for forensic document examination (FDE) work when implemented as outlined in this paper.

Abstract The superglue fuming process is widely used to develop latent fingermarks in the forensic community. That is why we confidently submitted this method for accreditation both in our central and departmental forensic laboratories. A review by non-practitioner auditors raised a point for which we had no answer. “Why must you heat cyanoacrylate to 120 °C?”. While the influence of humidity on the quality of fingermark development has been abundantly studied and published, we found no publications about the optimal cyanoacrylate fumigation temperature. We wonder if the quality of a fingermark developed by the superglue fuming process could be better at a different temperature. The aim of this study is to estimate the influence of the fumigation temperature on the quality of developed fingermarks for a constant humidity rate. The results show that the quality of a fingermark is appreciably better at 150 °C but a temperature of 120 °C gives very satisfactory results.

Abstract The majority of forensic laboratories use powder suspensions such as “wet powders” to develop fingerprints on adhesive tapes. These solutions are made of water, detergent, and particles that colour the mixture black or white. They are applied with a brush onto the surface to be treated. The operation may be complicated according to the length of the adhesive and the ability to wash off the tape using running water. In order to simplify the use of this method involving powder suspensions, the Fingerprints Unit of the Forensic Science Laboratory of the French Gendarmerie has developed a new working tool to facilitate treatment, rinsing and waste management.

Abstract Two cases where elemental mercury was intentionally added to the victim’s food are briefly described. Elemental mercury may be identified by using a combination of physical properties (appearance and specific gravity) and elemental analysis (scanning electron microscopy-energy dispersive X-ray spectrometry).

Abstract Fraudulent mislabeling of fish products has been reported with some frequency, representing an important problem in the food industry and regulatory agencies of many countries. This case reports a fraudulent substitution of shark fillets for the much cheaper Striped-catfish, in a large purchase for public elementary school meals in a Brazilian town. The economic and nutritional aspects involving such mislabeling demonstrate a serious fraud that should alarm governmental regulatory agencies to implement a more rigorous and frequent monitoring system on the species verification to guarantee the safety and quality of seafood.

Abstract This research validates the accuracy and efficacy of Sherlock, a recently developed program that estimates the area of origin (AO) of an impact pattern. Sherlock is an open-access, web-based software that conducts trajectory analysis by using the tangent method to estimate the area of origin. Fifty impact patterns were created at known X-, Y-, and Z-coordinates and were analyzed by upper year forensic science undergraduate students at Trent University. Individual stain data collected for each pattern were analyzed by both Sherlock and BackTrackTM/WIN. In this validation, we assess two objectives. The first evaluates the overall accuracy of the Sherlock program and the second compares the AO results between Sherlock and BackTrackTM/WIN when analyzing the same stain data. The average absolute deviation from the known using Sherlock was found to be 5.6 cm for the X-coordinate, 2.3 cm for the Y-coordinate, and 6.6 cm for the Z-coordinate. Further, when comparing the three-dimensional (3D) coordinate vector values, which considers all three coordinates as a single value, the Sherlock and known 3D AOs were shown to be similar with an average absolute deviation of 3.5 cm. Comparison between BackTrackTM/WIN and Sherlock provided statistically similar results for all comparisons (p > 0.05 in all cases), with average absolute deviations of 0.28 cm, 0.13 cm, and 0.75 cm in the X-, Y-, and Z-coordinates, respectively. This research demonstrates that the accuracy of the Sherlock program is comparable to a previously validated AO analysis program with similar absolute deviation from the true AO for single surface impact patterns.

Abstract A document expert is often asked to evaluate the authenticity of writings. In a normal situation, the evaluation of the similarities and the discordances observed between a questioned sample and the reference material allows to support or infirm the hypothesis of authorship. However, when dealing with writing from aged people or people affected by a disease, the examination is more complex and natural variation can sometimes be confused with simulation’s characteristics. It is the case with Alzheimer Disease (AD), a pathology that often develops in elderly and can change considerably, sometimes in a really short period of time, a person’s handwriting. In those cases the expert can benefit from specific literature on the subject. Unfortunately, most of the papers are relevant to the medical fields and the impact of the disease on the writing process is presented in relation to a disruption at a particular writing process’ level. In order to better understand the influence of AD on handwriting it is therefore fundamental to first understand the normal, healthy, process of text production. Once all the steps reviewed, it will be possible to decipher the impact of a deficit on a particular level on the resulting handwriting. This review aims at offering an overview of the influence of AD on handwriting by analyzing medical papers from a forensic point of view. This article is meant to help the document expert in cases where the questioned writing sample has been produced by a person affected by AD.

Abstract We report a case of a shooting incident where analysis of airbag residue was of critical importance to interpret the forensic significance of gunshot residue (GSR) found on a suspect. The suspect had allegedly fired a gun at the victim after having been involved in a motor vehicle collision. Airbags in the suspect’s vehicle had deployed during the collision, potentially exposing the suspect to a non-firearm source of GSR-similar particles. Samples collected from the interior of the deployed airbags were analyzed using scanning electron microscopy and energy-dispersive X-ray spectroscopy (SEM-EDS) and no particles similar to particles characteristic of GSR were found, eliminating the airbags as a potential source of GSR found on the suspect.

Abstract Research literature shows that different forms of aqueous electrolytes develop latent fingermarks on metals, glass and plastic surfaces. These reports describe the development of latent fingermarks using specific electrolytes for specific surfaces. Surface dependency is still a challenge in the fingerprint development process. The current study involves a newly formulated aqueous electrolyte reagent (AER) applied on a variety of surfaces. A proposed reaction mechanism has also been studied and supported by SEM-EDS. A large variety of porous, semi-porous, and non-porous surfaces have been tested for the development of latent fingermarks. Satisfactory response of AER has been observed.
