Project Description

Chemical traces, such as gunshot or arson accelerant residues, are common evidence types that can assist in the investigation of many serious crimes. Despite, however, the inherent abundance of information that could be extracted from their analysis, often just a small proportion is exploited in current routine analysis and, usually, also only for the purpose of identifying the type of material involved. Questions with a potentially higher impact in crime investigation, such as establishing the source of the analysed residues and/or inferring the specific activity that generated them, are still rarely addressed, mainly due to the complexity associated with the extraction and interpretation of the related chemical features.
This project aims to develop new inter-disciplinary approaches to extract enhanced forensic evidence and/or intelligence from chemical traces and, therefore, improve their role in the criminal justice system. In this regard, recent literature has shown that the application of non-targeted, omics-inspired methods coupled to next-generation chemometrics, as used in other analytical fields, could also assist forensic scientists in efficiently approaching complex problems in chemical criminalistics. The potential of these approaches will thus be explored throughout the project, in order to provide easy-to-use solutions to be implemented in an operational context. In particular, new comprehensive, multi-residue techniques will be developed for the analysis of common chemical residues and coupled with modern chemometric methods, based on machine learning and artificial intelligence, for the interpretation of extracted data. This will allow new tools to be proposed to effectively model relationships between physical traces, as well as their formation and transfer phenomena. The future benefits will be broad, with potential opportunities for extension to other scientific fields, such as environmental sciences.
