Global interlaboratory study: Assessing consistency and accuracy for determining source of...
Images containing faces, body parts, vehicles, weapons, clothing, luggage, furniture, landscapes, and buildings are routinely sent to forensic laboratories for comparison. Trained forensic practitioners offer an opinion regarding a common source or a different source. Results fro...
Study on the thermal damage traces of common textile fibers after simulated transient...
Gas explosions often result in the loss of biological evidence. This is due to transient thermal exposure and extreme destructiveness. Such conditions pose significant challenges to the identification of suspects and the reconstruction of their behavior. Clothing fibers act as di...
Evaluating the use of a novel expert system for interpretation of media authentication...
The evolution of artificial intelligence has enabled the creation of hyper‐realistic synthetic images and videos, significantly complicating the authentication of media evidence. Many algorithmic approaches to media authentication have proven ineffective in digital forensics, par...
Area of origin analysis for expirated patterns using HemoVision
Although bloodstain pattern analysis (BPA) can be performed on various types of patterns, there is a lack of research looking into whether the area of origin (AO) can be determined for expirated patterns. Expirated patterns are formed when blood is pushed out of an opening in the...
Illegal electric fencing acting as a death trap in a suspected homicide
Electrocution fatalities most commonly occur in domestic or occupational settings. When such deaths are found in remote outdoor locations, they often raise suspicion of homicide or deliberate body disposal. Deaths due to illegal electric fencing are rare and usually accidental, o...
Not a firearm: A case report of a fatal penetrating pseudo‐ballistic neck injury from...
Fatal injuries caused by defective airbag inflators are increasingly recognized as a distinct forensic and medicolegal issue. We describe the case of a 51‐year‐old male driver who was transported by emergency medical services following a low‐speed frontal collision with a palm tr...
Deep learning in image forgery: A systematic review for risk of bias (RoB)
Image forgery (IF) is a critical issue that can lead to the misinterpretation of visual information. Conventional strategies for IF detection are primarily manual feature‐based and therefore require further analysis. Artificial intelligence (AI) has shown a positive impact in the...
A forensic evaluation method of stable diffusion‐generated images using feature‐based...
With the increasing realism of artificial intelligence (AI)‐generated images from Stable Diffusion and similar models, forensic practitioners face significant challenges in image authenticity verification. This study proposes a feature‐based likelihood ratio model based on deep l...
Quantitative study on the discriminative value of fingerprint minutiae
Traditional fingerprint identification primarily relies on the number of matching minutiae between the questioned and reference prints, where identity is determined by whether the match count exceeds a fixed threshold. However, this "minimum matching pair threshold method&qu...
Eyes on the water: How local mariners can accurately detect a submerged human proxy in...
It has recently been demonstrated that modern recreational fish finders with high‐frequency (800 kHz) Sidescan transducers can detect submerged human bodies. This ubiquitous technology is widely used on the water and has the potential to be utilized for the rapid detection of sub...
Considerations for multivariate approaches to classify blow fly species based on cuticular...
Blow flies are early colonizers of human remains, allowing their developmental rates to be used to estimate postmortem interval (PMI). Accurate species identification is essential for PMI estimation, yet traditional methods can be subjective. Recently, the use of cuticular hydroc...
Automated particle analysis of D.B. Cooper's tie
Automated particle analysis (APA) using scanning electron microscopy (SEM) and energy‐dispersive x‐ray spectrometry (EDS) is a well‐known method in forensics, especially as it is applied to gunshot residue analysis. Here we describe the analysis of particles lifted from D.B. Coop...
Determination of mitragynine concentrations in medicolegal death investigations at the...
The prevalence of mitragynine, the major psychoactive component in kratom, has increased in forensic toxicology casework due to its current legal status and ease of accessibility in local shops and the online community. This study presents 28 death investigation cases from 2022 t...
Evaluation of illicit drug contaminants in seized cannabis in Arizona and California, 2023...
Despite public health concerns, fentanyl, cocaine, and other illicit drug contaminants remain largely understudied in unregulated cannabis. Here, we developed an analytical method to quantify a panel of common illicit drugs in cannabis and tested the law enforcement seizures in A...
From 15,000 to near zero: Cuyahoga County's eight‐year effort to address lawfully “owed”...
This study presents the final outcomes of an eight‐year, countywide initiative to address "lawfully owed" DNA (LODNA) among individuals who should have had a DNA sample in the Combined DNA Index System (CODIS) following a qualifying arrest or conviction but did not. Bui...
Discriminative features and contextual cognitive bias effects between robotic and natural...
This study aims to systematically identify the discriminative features between robotic and natural handwriting and explore how contextual conditions influence the classification accuracy of two groups of discriminators: forensic document examiners and nonexaminers. Repeated measu...
Analysis of circumstances in police‐related fatalities comparing medical examiner records...
Assessing circumstances surrounding police‐related deaths is hampered by the absence of an official national database. The National Vital Statistics System, which compiles death certificates filed by medical examiners and coroners, misses approximately one‐half of deaths due to p...
Diagnostic correction based on toxicology: A case of combined dichlorvos (DDVP), ethanol,...
Organophosphate pesticides (OPs) are commonly encountered toxic substances in poisoning incidents, often associated with severe clinical symptoms. The diagnosis and treatment become more complicated, especially when mixed with other toxic substances, requiring detailed toxicologi...
Investigation of eosin Y as a colorimetric sensor for the detection of fentanyl...
The increasing prevalence of fentanyl within the illegal global drug market underscores the need for rapid, low‐cost, and straightforward detection methods. Eosin Y demonstrates a measurable color change in the presence of fentanyl, making it a promising candidate for colorimetri...
