Research and development

Plastic bags are present in many criminal cases. Analyzing these bags in a forensic case can sometimes identify the manufacturer. More importantly, forensic comparison of bags from a known box or other known source can determine whether the bag could have originated from that source. This webinar discusses the manufacturing process, class and randomly acquired characteristics, examination techniques, and comparisons between questioned and known bags. The final segment includes a discussion of recent research in this area, followed by a question-and-answer period.

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.
