The Forensic Examination and Comparison of Plastic Garbage Bags
August 2024
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.
