The INTREPID program: Linking illicit fentanyl‐containing tablets and powders seized at US...
Three US government agencies, the Drug Enforcement Administration (DEA), Customs and Border Protection (CBP), and Food and Drug Administration (FDA), established a collaborative program to leverage each agency's expertise and capabilities to characterize illicit fentanyl‐con...
Effects of iTunSMPB metadata on decoded PCM stream hash reproducibility in iOS AAC audio...
Decoded pulse‐code modulation (PCM) stream hashing is used for forensic content verification, yet its reliability depends on decoder output stability. This study examines whether the iTunes Seamless Playback (iTunSMPB) metadata field affects decoded PCM alignment and stream hash ...
Characterization and differentiation of aluminum powders used in improvised explosive...
Many readily available online videos and instructional manuals provide information on how to manufacture aluminum (Al) powder, a component in pyrotechnics and improvised explosive devices (IEDs) using common household materials. Given the ease in acquiring and producing Al powder...
Comparative evaluation of adhesive tapes and stamps for touch DNA collection from textile...
A substantial proportion of forensic evidence consists of skin or contact traces, commonly referred to as touch DNA. The collection of such biological material remains challenging due to its invisibility and low abundance. Further, depending on substrate type and surface properti...
Firearm sexual homicide offenders: Criminal careers, psychopathology, and offense conduct
Most homicides are firearm‐perpetrated, but in sexual homicide, offenders are more likely to utilize personal weapons (e.g., hands and feet), contact weapons (e.g., blunt object), or edged weapons (e.g., knife) to comport with their fantasy life, motivational states, and psychopa...
MobDedup: Mobile data deduplication for enhancing digital forensics
Smartphones provide crucial but duplicate information in forensic investigations. The major deduplication tools designed for the cloud ignore constraints on phone storage, power, data fragmentation, and dynamic handling, leading to processing delays and limiting their efficient u...
A comparison of forensic anthropology casework across two urban Midwest Medical Examiner's...
Forensic anthropology has garnered greater attention in the academic and medicolegal communities with more practitioners embedded in Medical Examiner's and Coroner's offices. Practitioners have varied roles and responsibilities, leaving few opportunities to compare the ...
Development of latent fingermarks on the surfaces of photo paper
Photo paper is frequently encountered in forensic investigations; however, latent fingermark development remains challenging because its surface characteristics vary according to the manufacturing process and coating structure. This study investigated suitable methods for develop...
Effect on the likelihood ratio when under‐ and over‐assigning the number of contributors...
The availability of highly sensitive multiplex kits has resulted in the more common observation of low‐level and more complex (multiple contributors) DNA profiles within forensic casework. With the emergence of probabilistic genotyping software these complex DNA mixture profiles ...
Comparison of automated and manual DNA differential extraction in mock vaginal sexual...
Differential extraction is a core forensic DNA technique separating sperm cells from epithelial cells in sexual assault evidence, facilitating recovery of male DNA profiles from mixed biological samples. Effective physical separation reduces the occurrence of mixed DNA profiles, ...
Forensic characterization of transparent traces: A spectroscopic and chemometric approach...
Clear or unpigmented lip gloss, in particular, has become quite popular among people of all genders. Their unpigmented characteristics make them less noticeable at the crime scene; thus, they are less likely to be intentionally removed by the perpetrators. Therefore, in the prese...
Enhancing PRNU‐based camera identification by denoising filters and similarity metrics
Source camera identification through photo response nonuniformity (PRNU) analysis is a well‐established forensic technique, yet the choice of experimental conditions and parameters of the algorithms critically impacts identification reliability. For the first time, this study sys...
New PMCT multi‐indicator ossification standards for age estimation of the knee in modern...
Skeletal age estimation is crucial to medicolegal work, aiding subadult identification, and living age assessments in legal contexts. This study aims to document the ontogeny of knee skeletal indicators on post‐mortem computed tomography (PMCT), and quantify interpopulation varia...
Noncoronary sinus of Valsalva aneurysm with rupture into the right atrium
Sinus of Valsalva aneurysm (SVA) is a rare cardiac anomaly, with autopsy‐confirmed fatal cases remaining uncommon. This report presents a rare case of sudden death in a 13‐year‐old male adolescent caused by rupture of a noncoronary SVA into the right atrium, resulting in acute ci...
Explainable copy‐move forgery detection in videos: Generative adversarial network‐based...
With the nascent reliance on unmanned aerial systems as a means of surveillance, security, and monitoring, it is essential to ensure that video data legitimacy is assured. Object‐based Copy‐Move Forgery (CMF), in which an object is either copied or moved in the frame or across a ...
