Evaluation of the ForenSeq™ MainstAY workflow for forensic DNA samples

This study evaluated the performance and limitations of the ForenSeq™ MainstAY chemistry on the MiSeq FGx® Sequencing System, which is approved for National DNA Index System (NDIS) use. This study included baseline performance, sensitivity and reproducibility studies, challenging...

Toward a documentary standard for performance testing of terrestrial laser scanners used...

This paper documents efforts by members of the Crime Scene Investigation and Reconstruction (CSIR) subcommittee within the Organization of Scientific Area Committees (OSAC) for Forensic Science, in collaboration with researchers at the National Institute of Standards and Technolo...

Semen extraction efficiency and recovery before and after washing from reusable period...

When sexual assault evidence kits do not yield biological evidence demonstrating sexual contact, clothing such as undergarments is evaluated for the presence of semen. Menstrual underwear is a new type of undergarment and feminine product encountered as evidence in sexual assault...

Occupational burnout in forensic pathology practice: Balancing caseload, emotional...

This mixed‐methods study investigates occupational burnout among forensic pathologists in Pakistan, incorporating a quantitative survey of 250 participants and qualitative interviews with 20 pathologists. This study investigated burnout using the Maslach burnout inventory (MBI) a...

Development of artificial latent fingerprint solution using a novel lipid composition and...

Latent fingerprint research requires reproducible test materials that realistically mimic natural prints for the evaluation of development techniques. This study presents a novel artificial latent fingerprint solution that incorporates lipid components derived from the human body...

A research‐focused framework for empirical method validation in digital and multimedia...

This article presents a research‐focused structured framework for validating empirical methods in digital and multimedia forensic science. Grounded in foundational principles from traditional forensic disciplines, the framework bridges methodological gaps by adapting validation s...

An experimental study of bullet mass and velocity and their relation to fracture patterns...

This study investigated relationships between bullet mass, velocity, kinetic energy (KE), and fracture propagation in flat bones. Sixty full metal jacketed 9‐mm bullets of different masses were fired at pig (Sus scrofa) scapulae. A chronograph measured bullet velocity prior to im...

Comparative study of alkaline digestion and solvent‐assisted grinding methods for the...

Hair can trace drug use history, but prevailing extraction methods often struggle to fully extract analytes because of tight encapsulation by hair keratin. Since etomidate (ET) was controlled as a Category II psychotropic drug in China in 2023, developing an analytical method to ...

Fatality due to falling bullet

Falling bullets, resulting from celebratory or random gunfire, represent a predictable yet often overlooked public safety problem. Unlike classical firearm injuries, they usually lack external findings typical of close or intermediate‐range gunshot wounds, which complicates diagn...

Assessment of risk factors and preventive measures for inorganic and organic GSR secondary...

This study monitored the transfer of inorganic and organic gunshot residues (IGSR and OGSR) in cases where indirect exposure might be questioned, such as during arrests. Mock arrest scenarios (n = 180) were created to assess the effect of two variables on the secondary transfer. ...

Introduction to JFS Special Section on Vicarious Trauma in Forensic Scientists

Forensic interpretation of zolpidem in South Korea (2022–2024): Postmortem specimen...

Zolpidem, a non‐benzodiazepine hypnotic, is one of the most widely prescribed sleep aids in South Korea and is frequently implicated in forensic toxicology. A retrospective analysis was conducted on zolpidem‐positive autopsy cases (N = 1583) investigated by the National Forensic ...

Prior bleaching of virgin or colored hair has minimal impact on SERS‐based hair dye...

In many criminal investigations, scalp hair is commonly used as physical evidence that can be used to identify the suspect. People commonly dye their hair, which requires prebleaching of virgin and previously colored hair. Surface‐enhanced raman spectroscopy (SERS) is a minimally...

Enhancing DenseNet networks for improved forensic image analysis and tampered image...

The increasing sophistication of image manipulation techniques challenges traditional forensic image analysis (FIA) methods. Detecting tampered images accurately and efficiently has become crucial, particularly in sectors like law enforcement and media. The objective of this rese...

Recognizing and mitigating the effects of occupational exposure to traumatic death in...

Forensic anthropologists regularly come into direct contact with decedents affected by skeletal trauma, and consequently can experience high levels of indirect trauma exposure. However, beyond their nominal inclusion in self‐reported surveys of the general forensic science popula...

Non‐destructive identification of correction pens and tapes in document fraud using ATR...

A significant portion of document fraud cases, often associated with organized crime, involves the manipulation of physical records using correction materials such as pen or fluids and tapes. Although these materials are visually similar, they differ in chemical composition. Flui...

A preliminary investigation into the classification of wipe and swipe bloodstain patterns...

Bloodstain pattern types, such as wipes and swipes, are frequently encountered at crime scenes and can offer critical insight into the sequence of events. However, these pattern types can be difficult to reliably distinguish, highlighting the need for modern, objective approaches...

Enhanced trauma‐informed policing (E‐TIP): A neurocognitive, organizational, and...

Police officers operate at the intersection of pervasive community trauma and persistent organizational stress, making them uniquely vulnerable to potentially psychologically traumatizing and morally injurious events. The impact of this chronic trauma exposure can be either mitig...

Assessing vicarious trauma and attitudes toward mental health services for forensic...

Research indicates that forensic science professionals operate under significant pressure, the magnitude of which varies depending on their field, workload, case type, tenure, and the evidentiary significance of their testimony in court. This study conducted a needs analysis of f...
