Protodesnitazene: The identification and tissue distribution of a new nitazene
Multiple new analogues from the 2‐benzyl benzimidazole or "nitazene" class of drugs have emerged on the drug market in recent years. Nitazenes are highly potent μ‐opioid receptor agonists that present a substantial public health concern due to their elevated risk of sev...
Firing cycle dynamics and forensic interpretation of 3D‐printed Ruger 10/22‐pattern .22 LR...
Polymer receivers fabricated by fused filament fabrication (FFF) are increasingly encountered in forensic casework; however, their firing‐cycle behavior and the stability of associated ballistic toolmarks remain poorly understood. In this study, Ruger 10/22‐pattern FFF‐printed re...
Accelerated DNA profiling through workflow reconfiguration: Practical experience from 2...
The identification of human remains in mass‐casualty incidents requires rapid and reliable forensic DNA analysis, particularly when dealing with degraded skeletal material. Although rapid forensic identification is a fundamental objective in all disaster victim identification (DV...
Forensic data deduplication: A comprehensive survey of methods and challenges for digital...
The exponential expansion of digital evidence across traditional computing systems, mobile devices, cloud infrastructures, and IoT ecosystems presents new issues for forensic investigators. Modern forensic acquisitions frequently produce multi‐terabyte datasets with substantial i...
Reconstructing user behavior with Android and iOS app‐switching artifacts
Smartphone operating systems generate artifacts such as snapshots, state databases, and usage logs to manage application state transitions during app‐switching. However, these artifacts differ across operating systems in storage location, format, and retention period, which limit...
A juvenile homicide associated with a left‐sided cerebral arteriovenous malformation
Brain lesions are known to affect cognition, emotions, and behavior, and have been implicated in cases of violence, particularly when involving neural circuits responsible for impulse control, emotional regulation, and judgment. While tumors, traumatic brain injuries, vascular ab...
Performance evaluation of a scent transfer unit for sampling of explosives and their...
Volatile organic compounds associated with explosives such as Composition C‐4 serve as important targets for canine training as well as field analysis. In parallel, 1‐bromooctane (1‐BO) is a benchmark to contextualize canine performance and aid interpretation of results. Improved...
Field validation of blow fly age estimation methods for determining time of placement of...
Forensic entomology currently represents one of the best approaches for estimating the minimum postmortem interval (PMIMIN) in medicolegal death investigations given certain parameters and assumptions are met. However, validation of standard estimation methods used in this field ...
HPLC‐UV quantitation of synthetically derived THC, THCP, and HHC isomers in commercial...
Synthetically derived tetrahydrocannabinol (THC) products, including vaping liquids and edibles, are widely available in the US. Serious adverse events associated with the use of THC products are reported in large‐scale studies for both adults and children and include intoxicatio...
Dura mater‐preserving technique for fetal brain extraction after intrauterine death with...
Examination of the fetal brain represents a crucial step in the diagnostic assessment of fetal death in utero, particularly in cases of unexplained intrauterine fetal death (IUFD). Prolonged intrauterine retention, advanced autolysis, and the intrinsic structural immaturity of th...
Reading between the lesions: Recognizing intent in pediatric burn injuries
Burn injuries are common in childhood and may occur in accidental or non‐accidental circumstances, making forensic interpretation challenging. Evaluation is difficult when clinical findings, reported history, and contextual evidence are incomplete or discordant. We present three ...
Recording living and postmortem friction ridge patterns using image processing and a fiber...
Recording friction ridge patterns is a critical step in personal identification, as only clear impressions can be reliably compared with database records. This study presents two approaches — image processing and a fiber‐optic‐inspired total internal reflection method (FOM) —...
Defining overkill homicide through quantitative criteria: Evidence from a retrospective...
The forensic identification of "overkill" homicide remains challenging due to the absence of a standardized, evidence‐based definition. This study aimed to address this gap by establishing a quantitative criterion and delineating the criminological profile of overkill i...
Forensic challenges in a case of suspected filicide, matricide, and post‐mortem...
Familicide represents one of the most complex forms of domestic violence in forensic practice. Among intrafamilial homicides, filicide and matricide pose major medico‐legal and criminological challenges, particularly when autopsy findings are nonspecific or severely altered by po...
Exploring feature variability in digitally captured signatures—Part I: Variability in...
Digitally captured signatures (DCSs) pose new challenges for forensic handwriting examination compared with paper‐based signatures. While DCSs provide spatial coordinates, time and force values for forensic examination, the variability of the features derived from these data rema...
Family mass murder in the United States, 1970–2019: Perpetrator mental health...
Examining perpetrator characteristics of, and risk factors for, different types of mass murder, such as family mass murder — the most common type — could have important ramifications for preventive efforts. Histories of domestic violence and mental illness are of particular i...
Effects of bleach on carcass postmortem microbiomes and necrophagous beetle carcass...
Forensic entomology, and potentially microbiology in the future, can be used during death investigations to corroborate an estimated time since death. Instances where products are introduced to a cadaver, either in attempt to conceal or by accident, can affect decomposition and s...
Forensic analysis of gasoline residues in urban soil samples: Consequences for vehicle...
A substantial proportion of forensic fire investigations involve vehicle arson, where severe thermal damage often limits direct evidence recovery. Consequently, soil samples from the vicinity are frequently analyzed for ignitable liquid residues (ILRs). This study evaluates the f...
