Fingerprints hold a crucial position in forensic science, primarily for identification purposes, with thumbprints emerging as the most frequently recovered evidence at crime scenes. The main purpose of the present study was to conduct a comparative analysis of thumbprints of siblings and non-sibling pairs to investigate resemblance and similarities in fingerprint patterns. Thumbprints of 144 individuals (72 siblings and 72 non-siblings) from 36 families were obtained.

Technological advancements have allowed the detection of increasingly complex forensic genetics samples, as minimum amounts of DNA can now be detected in crime scenes or other settings of interest. The weight of the evidence depends on several parameters regarding the population and sample-related analytical factors, the latter in a greater number when the DNA amount is considered. This led to the development of probabilistic genotyping software (PGS), able to deal with the associated complexities.

Despite cultural references to the dangers of hitchhiking, particularly for sexual homicide, no published research investigates these incidents from both an offender and crime scene perspective. Using the Sexual Homicide International Database (SHIelD), we explore lifestyle risk by comparing sexual homicide cases involving hitchhiking victims to those involving victims engaged in sex trade work. The results, based on the use of bivariate and multivariate statistics, indicate that offenders view hitchhiking victims as opportunities for confinement without physical restraint, often engaging in sexual acts and theft.

Matrix-assisted laser Desorption/Ionization Mass Spectrometry Imaging (MALDI MSI) is an analytical technique used for the spatial mapping of drugs, explosives, and organic samples, making it a game-changer in Forensic examination. It detects a wide range of biomolecules in their native state without specific tags, antibodies, labels, and dyes. This review aims to highlight the advancement of MALDI-MSI over time and its impact on Forensic Science due to high-resolution molecular imaging.
