Investigation of the impact of a sound suppressor on the weapon's memory effect and...
The firearm's memory effect describes circumstances where particles from previous firing cycles are deposited with or incorporated in the new ammunition debris. Even though this phenomenon is well studied, the influence of a sound suppressor on the strength of the memory eff...
Issue Information
Combining virtual endoscopy and postmortem computed tomography to identify airway...
Peritonsillar abscess (PTA) is the most common deep neck infection, with well‐known complications such as airway stenosis and aspiration pneumonia. However, death due to asphyxia caused by PTA is extremely rare in forensic research reports. Traditionally, the autopsy is the stand...
A retrospective search of postmortem examination reports indicates that death following...
The aim of this study was to review the deaths associated with chiropractic treatment in Australia. The National Coronial Information System (NCIS) was searched for cases in Australia for which chiropractic treatment was determined to have contributed to death. Closed, completed ...
Identifying bromazolam, etizolam, and flualprazolam in blood using gas chromatography–mass...
Designer benzodiazepines are a commonly misused class of novel psychoactive substances (NPS) that present challenges for forensic toxicology laboratories and public health. Due to the difficulty in detection by routine toxicology methods, it is important to enhance the analytical...
Latent fingermark degradation processes by 3D imaging: The impact of substrate type and...
Friction ridge patterns, including those from latent fingermarks, are valuable physical evidence in the identification of individuals in criminal and humanitarian investigations. Although latent fingermarks may persist over extended periods, their time‐dependent degradation remai...
Hair root sonication washing impact on nuclei counts
In a previous study, hair samples were washed by sonication in Terg‐a‐zyme™ (Alconox, White Plaines, NY, USA) as part of the DNA extraction protocol. The sonication wash step was deemed necessary in the previous study because the DNA extracts could be used for both mitochondrial ...
A forensic engineering technique for analysis of an explosion incident
This article investigates the validity of current forensic practices to analyze an explosion event. The purpose of this study is to use forensic engineering techniques with the integrated models for the simulation of blast fragments and blast pressure to determine an explosive we...
The influence of perceived difficulty, availability of marks, and examination time on the...
Concurrent with studies on the accuracy, repeatability, and reproducibility of decisions based on comparisons of fired bullet and cartridge cases, we also collected the opinions of the participating examiners as to the characteristics of the specimens provided and the difficulty ...
Skeletal recovery rates in a New England environment
The present research examined the recovery rates of skeletal elements from forensic anthropology case report inventories at the Office of the Chief Medical Examiner, Massachusetts, with cases from 1979 through 2023 and from five contexts: terrestrial ground surface (n = 65), mari...
Documentation, investigation, and disclosure of contamination events
Examination of customized questioned digital documents
With the increasing trend of digitization of business processes and personal communication across the globe, digital documents of intrinsic value continue to be created. Whereas the questioned document examination (QDE) field of forensic science deals with the examination of &quo...
Sampling techniques and genomic analysis of biological material from artworks
The genomic analysis of biological material from artworks can be used to guide curation, preservation, and restoration. Additionally, human DNA recovered from artworks may provide other insights. However, the recovery of biological samples from artworks is dependent on the sampli...
Redefining the documentation of outdoor surface scatter scenes using geographic...
The field of forensic archaeology has been primarily associated with the search, location, and excavation of clandestine graves, and thus, other deposition types have been commonly neglected in research. Current literature typically addresses the use of traditional methods implem...
Impact of bifenthrin and clothianidin on blow fly (Diptera: Calliphoridae) oviposition...
Blow flies (Diptera: Calliphoridae) can detect decomposing remains and begin colonizing the resource through oviposition soon after. The estimated time between colonization and insect evidence collection is referred to as the time of colonization (TOC). Forensic entomologists use...
Improve the visualization effect of fingerprint immunolabeling based on biotin‐avidin...
Immunolabeling based on fluorescence is a new technique that has been recently applied in the field of forensic science. In this paper, a new immunofluorescence method based on signal amplification was applied to develop fingermarks and improve the quality of pattern recognition ...
A novel method for linking reciprocating saw blades, suspected of being used for theft, to...
In recent years, there has been a significant increase in metal prices, particularly precious metals. Consequently, property crimes involving metal theft, including the theft of auto parts and catalytic converters, have also increased dramatically. The surge in catalytic converte...
Methods to prevent overdevelopment of fingermarks with 1,2‐indanedione/zinc
A piece of paper submitted as evidence can both have fingermarks with a high and low amount of sweat. When such paper is treated with 1,2‐indanedione/zinc and subsequently heated at 160°C for 10 s, fingermarks with high sweat content may become overdeveloped. Attempts to prevent ...
Development of the house fly, Musca domestica L. (Diptera: Muscidae), on pork tissue at...
The house fly, Musca domestica, L. (Diptera: Muscidae), is a filth fly that is often associated with criminal and civil investigations surrounding abuse, neglect, and death of humans and other vertebrates. However, development data, which are crucial for determining the age of im...
Visual assessment for frontal sinus radiographic identifications: Documenting accuracy and...
Decedent positive identification via visual comparisons of frontal sinus radiographs is commonly used in the medicolegal field; however, only a handful of studies have empirically tested this method. This study aimed to test the accuracy of visual assessment in frontal sinus iden...
