Principles of Bloodstain Pattern Analysis

GMS6359

Elective Course
Credits: 3

This course provides foundational knowledge in the field of bloodstain pattern interpretation. It covers the scientific principles and practical applications of bloodstain pattern analysis in real casework. Emphasis will be placed on the accurate identification, thorough documentation, informed interpretation, and effective presentation of bloodstain patterns. The curriculum also addresses the analysis of multiple bloodstain events and the influence of cognitive bias.
