An understanding of prevalent work methods is essential to decipher the underlying decision-making logic in latent print comparisons, thereby fortifying the discipline's reliability. Despite the pursuit of standardized working practices, a burgeoning body of scholarly work has revealed that the impact of contextual elements extends to every component of the analytical process. In contrast, the available information regarding the types of data accessible to latent print examiners, and the kinds they frequently review, is quite limited. A survey of 284 practicing latent print examiners investigated the nature of accessible information and the types of information usually reviewed during their casework. We inquired as to whether variations in access to and the motivation to review different information types were evident across units of varying sizes and examiner roles. The data demonstrated that access to information about the physical evidence was almost universal among examiners (94.4%); the majority also possessed access to the type of offense (90.5%), the way evidence was collected (77.8%), and the names of both the suspect (76.1%) and the victim (73.9%). In contrast, the portrayal of the evidence (863%) and the means of its collection (683%) represented the only consistently analyzed information types by the majority of examiners. The study's findings reveal that examiners in smaller labs frequently review more diverse information types compared to examiners in larger labs, however both groups exhibit a similar tendency to avoid reviewing specific information. Examiner supervisors are more inclined to decline the act of reviewing information than examiners without supervisory responsibilities. While examiners generally agree on the categories of information they regularly review, findings reveal a marked disparity in their access to information, highlighting two key sources of variation in their methodologies: the work environment and the specific examiner function. This finding is significant, given initiatives to maximize the consistency and robustness of analytical processes (and the resulting conclusions). Further investigation is vital for future advancements in the field.

Psychoactive substances of different chemical and pharmacological profiles, encompassing amphetamine-type stimulants and emerging psychoactive substances, constitute the wide variety within the illicit market for synthetic drugs. In order to handle poisoning emergencies and devise standard forensic chemical and toxicological testing protocols, the chemical makeup, encompassing the type and quantity of active substances, holds significance. This research sought to determine the prevalence of amphetamine-type stimulants and novel psychoactive substances within the northeastern Brazilian states of Bahia and Sergipe, employing samples of drugs seized from 2014 to 2019 by regional police forces. A study of 121 seized and thoroughly examined samples, predominantly featuring ecstasy tablets (n = 101), uncovered nineteen different substances. Employing GC-MS and 1D NMR techniques, the substances identified included both established synthetic drugs and novel psychoactive substances (NPS). To analyze the components in ecstasy tablets, a GC-MS technique, previously validated, was used. A study on 101 ecstasy tablets indicated MDMA as the main substance in 57% of the samples, with quantities fluctuating from 273 to 1871 mg per tablet. Samples of MDMA, MDA, synthetic cathinones, and caffeine were also found in a combined total of 34 instances. The findings from northeast Brazil highlight a consistency in the types and makeup of seized substances, echoing prior studies conducted across various Brazilian regions.

Soil samples, assessed using environmental DNA, elemental, and mineralogical analyses, exhibit source-specific properties, prompting the exploration of airborne soil (dust) for forensic applications. Dust, found throughout the surroundings, readily attaches itself to items belonging to a targeted individual, making dust analysis an ideal method for forensic cases. The groundbreaking technology of Massive Parallel Sequencing enables metabarcoding of eDNA, exposing the genetic traces of bacteria, fungi, and plants hidden within dust. Analysis of the elemental and mineralogical characteristics of this dust sample offers multiple avenues of investigation into its origin. polymers and biocompatibility Dust analysis from a suspect is especially relevant for identifying potential travel locations. Nevertheless, before proposing dust as a forensic trace material, it is essential to determine the ideal sampling procedures and detection limits to delineate its applicability in this field. Several dust collection strategies, applied to various materials, were assessed to establish the lowest quantity of dust yielding results interpretable for eDNA, elemental composition, and mineralogical analysis, allowing for site distinction. The study confirmed the ability to obtain fungal eDNA profiles from diverse sample types. Tape lifts exhibited the highest efficacy for site-specific differentiation. Our results indicate successful recovery of fungal and bacterial eDNA signatures down to 3 milligrams, the lowest quantity tested, and also yielded elemental and mineralogical compositions for each sample tested. Dust extraction from various samples using diverse techniques is proven reliable, and the generation of fungal and bacterial profiles, along with elemental and mineralogical data, is shown to be possible from small sample sizes. This highlights dust's significant potential for forensic intelligence.
