Blood stain patterns

Welcome to our virtual poster session! The Forensic Technology Center of Excellence (FTCoE) would like to highlight student research in the forensic sciences! The FTCoE is grateful for all the universities, faculty, and students who took the time to prepare poster presentations for submission to this year’s event. We recognize your hard work, and we are here to celebrate and learn from your research.

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.

It is well-known that bloodstain pattern analysis (BPA) on textiles is difficult and subject to many errors or misinterpretations. In this webinar, we probe the reason for this and suggest useful information that a bloodstain pattern analyst may be able to extract from the observed bloodstains. The data set demonstrates the roles of drop volume and impact speed in bloodstain formation on textiles.
