Lessons Learned from Proficiency Test Results in Bloodstain Pattern Analysis

April 2021

This webinar will evaluate the submitted responses for bloodstain pattern analysis proficiency tests over the past several years with the purpose of gaining insight into trends within the science.  The focus will be on erroneous conclusions and how an evaluation of the most problematic patterns can assist in moving the discipline forward.

This webinar was presented by the NIJ Forensic Technology Center of Excellence on April 15, 2021.
