Qualitative transformations of street-seized ecstasy over a decade: A case study in Rio de Janeiro (Brazil)
This study presents the chemical fingerprinting of ecstasy tablets seized in the state of Rio de Janeiro (Brazil) between 2012 and 2021. The tablet samples were weighed, extracted, diluted with methanol, and acidified before analysis using gas chromatography high-resolution mass spectrometry and attenuated total reflection Fourier transform infrared spectroscopy. The major constituents found were MDMA and clobenzorex, with fewer occurrences of MDA, MDEA, and 2C-B. The results also indicate that the occurrence of mega-events in the study location impacted the chemical fingerprints of ecstasy. A total of 27 combinations of c...

Evaluating the impact of hot water killing larvae on gene expression using the transformer gene in Cochliomyia macellaria (Diptera: Calliphoridae)
J Forensic Sci. 2024 May 1. doi: 10.1111/1556-4029.15532. Online ahead of print.ABSTRACTIn forensic entomology, determining the age of a larva from a body to estimate time since death is commonly performed through the measurement of a physical trait. Gene expression has been studied as an alternative age estimation approach, but the storage conditions required for these studies are different than those used in forensic entomological casework. Studies analyzing gene expression prioritize the preservation of RNA, which requires fresh tissue and ultra-cold storage. Casework, in contrast, utilizes hot water killing specimens t...

Personal identification using frontal sinus coding methods: The effect of mixed image modality comparisons
J Forensic Sci. 2024 Apr 29. doi: 10.1111/1556-4029.15533. Online ahead of print.ABSTRACTSeveral code-based methods have been created for comparing the frontal sinus in skeletal identification scenarios. However, little is known regarding matched-pair accuracy rates of these methods or how varying image modalities may affect these rates. The goals of this study were to validate the exclusion rates and to establish matched-pair accuracy rates of two well-cited coding methods, Cameriere et al. [23] and Tatlisumak et al. [24]. Additionally, individual variables were assessed for consistency in scoring between image modalities...

The false promise of firearms examination validation studies: Lay controls, simplistic comparisons, and the failure to soundly measure misidentification rates
This article therefore utilizes such a group, specifically 82 attorneys, as a post hoc control and juxtaposes their performance on a comparison set of cartridge case images from one commonly cited study (Duez et al. in J Forensic Sci. 2018;63:1069-1084) with that of the original participant pool of professionals. Despite lacking the kind of formalized training and experience common to the latter, our lay participants displayed an ability, generally, to distinguish between cartridge cases fired by the same versus different guns in the 327 comparisons they performed. And while their accuracy rates lagged substantially behind...

Optimization of crystal violet technique for enhanced fingerprint detection on various surfaces
J Forensic Sci. 2024 Apr 29. doi: 10.1111/1556-4029.15534. Online ahead of print.ABSTRACTThe crystal violet (CV) staining technique represents a prevalent approach for the development of latent fingerprints, especially on adhesive tape surfaces. Nevertheless, the technique necessitates intricate formulations to augment its performance. In this investigation, an optimized CV staining protocol was developed, characterized by the absence of residual dye on the target substrates and the capability of facilitating fingerprint visualization under ambient light conditions. Four donors, comprising two males and two females, deposi...
