Identification of novel psychoactive substances (NPS) based on comparisons of electron-ionization (EI) mass spectra continues to pose challenges in seized drug analysis. In this webinar, a method to statistically compare EI mass spectra is described, and an application of the method to distinguish several structural and positional isomers of NPS analogs are demonstrated.

The Bureau of Justice Statistics (BJS) conducts the Census of Publicly Funded Forensic Crime Laboratories (CPFFCL) to provide insight into federal, state, county, and municipal crime labs that are funded solely by the government or whose parent organization is a government agency. The most recent CPFFCL provides national-level data on the workload and operations of crime labs during 2020. Of the 326 eligible crime labs and multilab systems in the 2020 CPFFCL, 293 (90%) provided responses to at least some of the survey questions.

This presentation explores a series of research studies aimed at assessing the accuracy, repeatability, and reproducibility of forensic pattern evidence examination decisions across various disciplines, including latent prints, firearms, shoeprints, and handwriting.  Key topics covered include a comprehensive overview of the design factors in these four large-scale research studies, as well as a response to common critical observations regarding the experimental design and the interpretation of results.

This webinar provides a means and rationale to prepare and execute the various steps of this process, including planning, gap analysis, educating key staff members, executing and delivering work products. The webinar introduces the process of standards implementation stepwise for key senior administrators whose laboratory system has not yet formally initiated a program.
