Individuals lacking ridge detail: A case study in adermatoglyphia
Adermatoglyphia is a very rare autosomal‐dominant condition that is genetically inherited and causes an individual to be born without conventional ridge detail on either their palmar or plantar surfaces (the fingers and palms of the hands and the toes and the soles of the feet). ...
A Semi‐quantitative method for the detection of fentanyl using surface‐enhanced Raman...
A handheld, spatially offset Raman spectroscopy (SORS) system was successfully used to obtain Surface‐enhanced Raman Scattering (SERS) spectra of fentanyl under simulated field conditions. A series of aqueous fentanyl solutions were prepared with commercially available gold nanop...
Corneal‐Smart Phone: A novel method to intelligently estimate postmortem interval
The changes of postmortem corneal opacity are often used to roughly estimate the postmortem interval (PMI) in forensic practice. The difficulty associated with this time estimate is the lack of objective means to rapidly quantify postmortem corneal changes in crime scenes. This s...
A rapid and nondestructive approach for forensic identification of car bumper splinters...
The proper identification of car bumper splinters at hit‐and‐run crime scenes is imperative to forensic investigations, as splinters yield crucial pieces of vehicle information that can lead to subsequent investigation resolution and criminal justice. A method based on attenuated...
The first step in an investigation of quantitative ultrasound as a technique for...
This study's purpose is to evaluate whether bone speed of sound (SOS) data, a parameter of quantitative ultrasound, collected from an infant autopsy sample are comparable to data collected from healthy, living infants. We hypothesize that SOS values obtained from deceased te...
Language use in ancestry research and estimation
Recent discussions have revolved around the concept of ancestry and ancestry estimation; however, the associated terminology and its theoretical underpinnings have not been similarly examined. This research evaluates the concepts (e.g., race, ancestry, ethnicity) currently in use...
A test of the Bulut et al. (2016) landmark‐free method of quantifying sex differences in...
The skull, along with the pelvic bone, serves an important source of clues as to the sex of human skeletal remains. The frontal bone is one of the most significant sexually dimorphic structures employed in anthropological research, especially when studied by methods of virtual an...
Results of the 3D Virtual Comparison Microscopy Error Rate (VCMER) Study for firearm...
The digital examination of scanned or measured 3D surface topography is referred to as Virtual Comparison Microscopy (VCM). Within the discipline of firearm and toolmark examination, VCM enables review and comparison of microscopic toolmarks on fired ammunition components. In the...
Beretta barrel fired bullet validation study
A report published in 2016 by the President's Council of Advisors on Science and Technology (PCAST) criticized studies that have been published regarding the discipline of firearm identification. This study was designed to answer some of these criticisms and involved 30 cons...
A comparison of three shoe sole impression lifting methods at high substrate temperatures
Footwear impressions are a common form of evidence found at crime scenes, and the accurate recovery and recording of such impressions is critical for shoe sole comparison and identification. The lifting of shoe sole impressions from hot surfaces (>30°C/86°F) and in hot environ...
Novel O‐propyl, S‐propyl, and N‐propyl substituted 1,4‐naphthoquinones and 1,4...
Lawsone is a 2‐substituted‐1,4‐naphthoquinone derivative, which has been proposed as an alternative to the reagents currently used for fingermark detection on porous surfaces. 2‐substituted‐anthraquinones, which contain an additional conjugated benzene ring, have a similar chemic...
Dermestes maculatus (Coleoptera: Dermestidae) development under fluoxetine effect using...
Fluoxetine is a selective serotonin reuptake inhibitor, commonly used for the treatment of a variety of psychopathological conditions. As such, fluoxetine may be expected to appear in clinical and forensic cases. Dermestes maculatus De Geer (Coleoptera: Dermestidae) has been reco...
Portable high‐resolution automated 3D imaging for footwear and tire impression capture
The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a majo...
Primary intimal sarcoma of the pulmonary artery misdiagnosed as pulmonary thromboembolism:...
Misdiagnosed PAS confirmed at medicolegal autopsy Pulmonary artery sarcoma (PAS) is a rare disease and usually indistinguishable from acute or chronic thromboembolic disease of the pulmonary arteries. We present a case of pulmonary artery sarcoma in a 54‐year‐old male, who was cl...
3D forensic facial approximation: Implementation protocol in a forensic activity
The primary objective of this paper is to report on the successful implementation of forensic facial approximation in a real case in the forensic context. A three‐dimensional (3D) facial approximation protocol of the skull was performed with free software, applying techniques in ...
Identification of furosemide in hair in a post‐mortem case by UHPLC‐MS/MS with guidance on...
Testing for drugs in hair raises several difficulties. Among them is the interpretation of the final concentration(s). In a post‐mortem case, analyses revealed the presence of furosemide (12 ng/mL) in femoral blood, although it was not part of the victim's treatment. The pro...
Evaluation and applicability of Alere iCup DX 14 for rapid postmortem urine drug screening...
Performing point‐of‐care urine drug screen testing at autopsy by a forensic pathologist may provide an early indication of the presence of analytes of interest during autopsy. An evaluation for the screening of 14 classes of common drugs of abuse in postmortem urine by the point‐...
Increased risk of fatal intoxication and polypharmacy among psychiatric patients at death
Patients suffering from psychiatric disorders have an excess mortality and a shorter life span expectancy compared to the general population. Furthermore, they are treated with multiple drugs and are known to have an increased risk of drug abuse. In this study, we aimed at invest...
Relevance analysis using revision identifier in MS word
Electronic documents often contain personal or confidential information, which can be used as valuable evidence in criminal investigations. In the digital investigation, special techniques are required for grouping and screening electronic documents, because it is challenging to ...
Characterization and differentiation of aluminum powders used in improvised explosive...
Aluminum (Al) powders are commonly used in improvised explosive devices as metallic fuels, a component of explosive mixtures. These powders can be obtained readily from industrial‐scale and consumer products, and produced using unsophisticated "kitchen chemistry" techni...
