Since 1995 heroin sample comparisons have been carried out in Viet Nam to establish links between wholesalers and retailers. To that end, the physical and chemical characteristics of samples are analysed: their colour, the packaging material, including fingerprints, diacetylmorphine (heroin) content and the composition of some main alkaloids. At the beginning of 2002, having acquired expertise ...

Over the course of the last two decades, DNA profiling has grown to be one of the most widely known and applied techniques for the identification of biological samples in forensic science. Arguably, the “fame” of DNA profiling is responsible for the courts’ current interest in the raising of standards for scientific examination of all forms of physical evidence (e.g., toolmarks, soils, fingerpr...

Since 2009, when Matrix Assisted Laser Desorption Ionisation Mass Spectrometry Imaging (MALDI MSI) was firstly reported for the molecular mapping of latent fingermarks, the range of information and operational capabilities have steadily increased. Pioneering work from our Fingermark Research Group exploited different modalities, including Profiling (MALDI MSP), tandem mass spectrometry (MS/MS) ...

STR-based DNA profiling is an exceptionally sensitive analytical technique that is often used to obtain results at the very limits of its sensitivity. The challenge of reliably distinguishing between signal and noise in such situations is one that has been rigorously addressed in numerous other analytical disciplines. However, an inability to determine accurately the height of electropherogram ...

Currently, criminal’s profile (CP) is obtained from investigator’s or forensic psychologist’s interpretation, linking crime scene characteristics and an offender’s behavior to his or her characteristics and psychological profile. This paper seeks an efficient and systematic discovery of non-obvious and valuable patterns between variables from a large database of solved cases via a probabilistic...
