Targeted recovery of male cells in a male and female same‐cell mixture
DNA mixture deconvolution in the forensic DNA community has been addressed in a variety of ways. "Front‐end" methods that separate the cellular components of mixtures can provide a significant benefit over computational methods as there is no need to rely on models with...
Considerations for age estimation accuracy: Method‐derived outcomes and practitioner...
Recent research observed 92% accuracy for age‐at‐death estimations by U.S. forensic anthropologists. The present study compares this case report level accuracy to method level accuracy for the most commonly used methods in U.S. casework, drawing from the Forensic Anthropology Dat...
Advances in postmortem fingerprinting: Applications in disaster victim identification
Postmortem fingerprinting is the fastest and most reliable way to scientifically identify unknown decedents from mass fatality incidents. In disaster victim identification (DVI), fingerprints, DNA, and dental examinations are the three primary methods of identification. Additiona...
Towards maintaining canine training aid integrity: Effects of environmental factors and...
There are many factors that may affect the longevity of or guide the use of canine training aids. Literature to date has mainly focused on identifying the headspace volatiles associated with training aids or odors and only minimal research exists into how different variables may ...
Isolation and characterization of reference standard candidates for cocaine and...
The area of forensic chemistry has been growing and developing as a line of research due to the high demands of public safety that require increasingly reliable results due to their importance in criminalistics. In this way, the development of new technologies that help this area...
Concentration units used to report blood‐ and breath‐alcohol concentration for legal...
This technical note reviews the plethora of concentration units used to report blood‐alcohol concentration (BAC) and breath‐alcohol concentrations (BrAC) for legal purposes in different countries. The choice of units sometimes causes confusion when scientific papers originating f...
An exploratory view into allelic drop‐out of sequenced autosomal STRs
As massively parallel sequencing is implemented in forensic genetics, an understanding of sequence data must accompany these advancements, that is, accurate modeling of data for proper statistical analysis. Allelic drop‐out, a common stochastic effect seen in genetic data, is oft...
A study on the estimation of area of origin of swing cast‐off pattern
In bloodstain pattern analysis (BPA), a field of forensic science, there has been active discussion on the estimation of the area of origin of impact spatter. However, there is no established methodology to quantitatively analyze the area of origin of a swing cast‐off pattern. To...
Postmortem chondrocyte viability in porcine articular cartilage: Influence of time,...
The aim of the present study was to investigate the effects of time, temperature, and burial in a natural environment on the viability of chondrocytes in porcine femoral condyles using confocal laser scanning microscopy. Hind trotters from 10 pigs were buried or left unburied. Sa...
Development research of latent fingermarks based on aggregation‐induced emission technique
Fingerprints hold evidential value for individual identification; a sensitive, efficient, and convenient method for visualizing latent fingermarks (LFMs) is of great importance in the field of crime scene investigation. In this study, we proposed an aggregation‐induced emission a...
The influence of altitude on the abundance and occurrence of species of the family...
A carcass is defined as a temporary resource that can support high levels of diversity compared to other resources. The level of diversity often depends on the environmental conditions in which the corpse is found. Calliphoridae (Diptera) are the most important necrophagous insec...
An evaluation of the cannabinoid content of the liquid and thermal degradation analysis of...
Cannabidiol (CBD) vape pen usage has been on the rise given the changing political and scientific climate as well as the promotion of these delivery systems as a more accessible and lower‐risk option for consumers. Despite being marketed as a safer way to use cannabis, CBD vape l...
Is it really possible to kill with insulin without leaving traces? From lifesaver to...
Evidence of an insulin overdose is very complicated in the medico‐legal field. The analysis and subsequent interpretation of results is complex, especially when treating postmortem blood samples. The instability of insulin, the special pre‐analytical conditions and the absence of...

Forensic analysis of iOS binary cookie files
iPhone operating system (iOS) devices utilize binary cookies as a data storage tool, encoding user‐specific information within an often‐neglected element of smartphone analysis. This binary format contains details such as cookie flags, expiration, and creation dates, domain, and ...
Targeted enrichment of whole‐genome SNPs from highly burned skeletal remains
Genetic assessment of highly incinerated and/or degraded human skeletal material is a persistent challenge in forensic DNA analysis, including identifying victims of mass disasters. Few studies have investigated the impact of thermal degradation on whole‐genome single‐nucleotide ...
The effect of the anti‐coagulant EDTA on the deposition and adhesion of whole blood...
An investigation into whether the addition of a commonly used anti‐coagulant agent like ethylenediaminetetraacetic acid (EDTA) has an impact on the adhesion potential of blood to non‐porous substrates was conducted. Two non‐porous substrates (aluminum and polypropylene) exhibitin...
Evaluation of porcine decomposition and total body score (TBS) in a central European...
The total body score (TBS) is a visual scoring method to scale the succession of decomposition stages. It compares decomposition between cadavers, to connect it with external taphonomic factors and estimate the post‐mortem interval. To study decomposition in various climatic envi...
Use of thermal drone in detection and assessment of larval mass temperature in decomposed...
Manual ground searches and cadaver dogs are traditional methods for locating remains, but they can be time‐ and resource‐intensive, resulting in the decomposition of bodies and delay in victim identification. Therefore, thermal imaging has been proposed as a potentially useful to...
DNA recovery after sequential processing of latent fingerprints on black polyethylene...
Latent fingerprints on plastic substrates can be visualized by using sequential treatments to enhance the contrast between the fingerprint residues and underlying substrate; however, the extent to which these processes affect subsequent DNA analysis is mostly unknown. Latent fing...
