The forensic footprint: Elemental and microbial evidence in relocated remains
Here, we investigate the microbial and elemental signatures left behind at the sites of relocated remains, providing insights into postmortem processes that can assist forensic investigations of clandestine burials and relocated remains. We allowed two 90.7 kg (200lbs) clothed po...
Air embolism as evidence of antemortem sexual activity
In the forensic autopsy examination of sexual assault cases, two essential questions must be addressed: whether sexual activity occurred, and whether sexual activity occurred antemortem or postmortem. However, confirming sexual activity can be challenging, particularly when the a...
Quantitative assessment of barrel wear from solid copper bullets
Forensic firearm and toolmark identification is based on the principle that firearms possess and impart individual characteristics on fired ammunition, which can be used to identify a bullet back to the barrel from which it was fired. However, these characteristics may change due...
Impact of Marabunta ants on post‐mortem interval estimation in pigs: Insights from Okuku,...
The rising homicide rates in Nigeria underscore the necessity for comprehensive post‐mortem interval (PMI) estimations to enhance the reliability of forensic investigations. This study investigates the impact of Marabunta ants (Hymenoptera: Formicidae) on the decomposition proces...
Determination of erythrocyte degradation levels and estimation of age blood spot using...
Blood stains can be used to understand the dynamics of a crime, to verify the identity of a suspect, to perform pattern analysis in reconstructing the incident, or to determine the time when a crime was committed. Changes in the cell and cell membrane surfaces of erythrocytes, wh...
Forensic analysis of small architectural and vehicle glass fragments using recent...
Glass fragments are frequently recovered during criminal investigations as they can provide links between the crime scene, suspects, or victims. The elemental composition of glass is often used to determine if there is a source commonality between glass samples. Micro‐X‐ray fluor...
Effects of sodium fluoride on serum concentrations of selected psychotropic drugs
Caution is imperative when interpreting drug concentrations in blood, plasma, or serum, given the potential variance in the distribution of a compound across these fluids. Preservatives, such as sodium fluoride, prove beneficial in preventing drug degradation in collected blood s...
