Fingerprint evidence recovery from gunshot casings presents considerable challenges for forensic researchers. While both fired and unfired casings are frequently discovered at the scene of violent crimes, recovering fingermarks and establishing a link between the perpetrator and the gun has consistently proven to be difficult due to the states that the projectile housings can reach during shooting and the techniques used to create and capture the fingermarks.

Specialists were prompted to look at the physical science involved by a real-life forensic puzzle, and in Physics of Fluids, they provide hypothetical findings that reveal a connection between the approaching vortex ring of force muzzle gases and the in reverse blood splash. This group has previously provided a point-by-point analytical theory of such ferocious self-comparative vortex rings that is mathematically related to the theory of quantum oscillators.

To assist the observation of chronic drug usage among originators, a team of specialists from the National University of Singapore (NUS) has come up with a different alternative. Three novel urine biomarkers have been identified by the team, led by a professor from the NUS Department of Pharmacy, that could be used to detect use of the growing synthetic cannabinoid ADB-BUTINACA, a new psychoactive chemical (NPS). It is possible to discriminate between other natural and synthetic cannabinoids using the same ground-breaking technology.

Legal researchers may still be constrained by the most prevalent method of preparing samples (blood, urine, etc.) for analysis and searching for more effective methodologies as logical instrumentation (gas- and liquid chromatographs combined with mass spectrometers) expands in responsiveness and speed.

Individual identification is one of the main objectives of the forensic anthropological examination of human remains. Authoritative techniques are used in the comparison between the recorded data gathered during one’s life and the data obtained by examining the corpse. The superimposition technique, frequently used in the craniofacial segment, was applied in the maxillomandibular segment in the cases presented herein. Studies on bi-dimensional photographic superimposition were performed by means of computer-generated images, using Adobe^® Photoshop^® CS 6.0 © (1990-2003 Adobe Systems Incorporated) for Windows. Image superposition can be an auxiliary means in the identification process and greatly contributed to the conclusion of the forensics of individual identification.
