“…10 In addition, a study by Vanderheyden et al showed that it is possible to recover DNA evidence on submerged improvised explosive devices. 11 Based on the aforementioned information, cellular retention on a substrate and how well the substrate protects deposited cellular material seems to play a role in the quality of DNA recovered from different items.…”

Background: Both duct tape and items retrieved from water are common pieces of evidence in forensic casework. However, there is little research uniting DNA recovery from immersed tape evidence. The goal of this study was to test the effects of submersion duration and initial cellular concentration on the ability to recover DNA and short tandem repeat (STR) profiles from folded duct tape that has been submerged in ocean water for up to 2 weeks (336 h), as well as the ability to recover touch DNA from such evidence. Methods: Strips of duct tape spiked with human cells or latent prints were submerged in the Delaware Bay. Samples were retrieved at specific intervals between 1 and 336 h of immersion in ocean water. After sample retrieval, DNA was extracted from the tape's adhesive surface and processed for STRs. Results:The results indicate that it is possible to recover enough DNA to yield a complete STR profile from folded duct tape that has been submerged in ocean water for up to 336 h, provided that the initial amount of cellular material is sufficient. It is also possible to recover touch DNA from latent prints, with full STR profiles recovered from samples submerged for up to 168 h (1 week). Overall, the durability and adhesive nature of duct tape seem to provide protection to cellular material on its surface while submerged in aqueous environments.

“…Several studies continue to elucidate the ability to generate DNA profiles from samples taken from touched objects [61][62][63][64]. Additional studies evaluated means of generating human DNA profiles from traces of biological material left on various items, includ-ing hair [65], bricks [66], dogs [67], bite marks in food [68], paper documents [69], eye wear [70], superabsorbent polymer-containing products (commonly found in nappies and sanitary towels) [71], improvised explosive devices [72], rifle magazines [73] and bullet cartridges [74][75][76][77][78]. Further, Gray et al [79] demonstrated that STR DNA profiles can be generated from human blood found in Anopheles mosquitoes, from one or multiple individuals, and that the quality of the profiles declined as the duration between mosquito blood meal and sample collection increased.…”

Understanding the factors that may impact the transfer, persistence, prevalence and recovery of DNA (DNA-TPPR), and the availability of data to assign probabilities to DNA quantities and profile types being obtained given particular scenarios and circumstances, is paramount when performing, and giving guidance on, evaluations of DNA findings given activity level propositions (activity level evaluations). In late 2018 and early 2019, three major reviews were published on aspects of DNA-TPPR, with each advocating the need for further research and other actions to support the conduct of DNA-related activity level evaluations. Here, we look at how challenges are being met, primarily by providing a synopsis of DNA-TPPR-related articles published since the conduct of these reviews and briefly exploring some of the actions taken by industry stakeholders towards addressing identified gaps. Much has been carried out in recent years, and efforts continue, to meet the challenges to continually improve the capacity of forensic experts to provide the guidance sought by the judiciary with respect to the transfer of DNA.

Fast characterization of compounds and components of explosives

Finding markers to detect and identify compounds and components related to an explosive is an important task that could reduce threats of unlawful uses of explosives. The capability of Raman spectroscopy to characterize chemical composition of explosive compounds and the analysis of stable isotope ratios could be useful to identify specific markers to identify the origin of the material used. Using Raman spectrometer directly on-site after the accident scene could be a useful tool for an immediate characterization of the components. In addition, carbon and nitrogen analysis on some fragments collected on the accident scene will then confirm the characterization of the components. The proposed configuration of double technique, coupled with a digital database and algorithms, could be useful to run analysis, with fast response time, in work environment related to emergency situations.
