Evaluation of Crime Scene Blood Spatters and Other Traces: Scope and Reliability [Engage & Exchange]

This presentation describes the scope of bloodstain pattern analysis (BPA), a forensic discipline which mainly aims at evaluating the physical events responsible for blood traces. The large error rates of about 10% are explained by the nature and methods of the discipline. By its nature, BPA associates activities to blood traces, a task inherently more complex than comparing two traces of the same nature, like DNA or fingermarks.
