Evaluation of latent fingerprint storage conditions by friction ridge volume and clarity
The storage and preservation of latent fingerprint (LF) evidence prior to processing is vital to forensic investigations. This study introduces a method to objectively quantify the degradation of LF topography by examining the effects of four different temperatures (40, 22, 4, an...
Fatal hyponatremia by massive ingestion of water to commit suicide
Hyponatremia (blood sodium level <136 mmol/L) is common in routine medical practice and is usually quickly resolved. Symptoms include headaches and edema. In the most severe cases, it can lead to neurological disorders and even death. A 33‐year‐old woman, who had been hospital...
Quantifying pairwise similarity of ignitable liquids analyzed by GC–MS: A comparison of...
For analyses that require the extraction and concentration of ignitable liquids, quantitatively comparing the similarity between samples obtained under experimental conditions to reference samples provides a straightforward way of defining the experimental response. Various metho...
Guardianship as a back‐door insanity strategy: Parricide, antisocial personality disorder,...
Intrafamilial homicide, particularly parricide, sits at a critical intersection of forensic psychiatry, criminal justice, and civil rights protection, and diagnostic labels generated in custodial settings may later shape high‐stakes civil decisions. We report the case of a 24‐yea...
Population‐specific validation of long bone linear discriminant analysis against...
Sex estimation represents a fundamental step in forensic identification protocols, traditionally relying on morphoscopic pelvic assessment. However, the increasing integration of machine learning approaches and population‐specific validation requirements necessitate comprehensive...

Effects of chemical and biological warfare agent decontaminants on trace survival: Impact...
Chemical and biological events present a challenging environment for forensic scientists to perform their work. This research is the follow‐up of the previous article that investigated the impact of decontaminants on fingermarks deposited on glass. In the present study, the focus...
Trends in toxicological findings and drug seizures of MDMA in New Zealand from 2010 to...
3,4‐Methylenedioxymethamphetamine (MDMA) or "ecstasy," is a commonly used drug worldwide, including in New Zealand, where 4.8% of the population aged 15 years or over reported using it in a 2023/2024 survey. This study provides additional insights on MDMA prevalence dat...
Fired bullet matching candidate retrieval algorithm based on Siamese neural network
In gun‐related crime investigations, analyzing fired bullets is critical. Traditional examination via comparison microscopes is labor‐intensive and time‐consuming, hindering investigation efficiency. To address these issues, this study uses a Siamese neural network (SNN) to suppo...
