Bloodstain Pattern Analysis

At a violent crime scene, bloodstains leave behind a silent but powerful testimony. Bloodstain Pattern Analysis (BPA) is a forensic discipline dedicated to interpreting these patterns to reconstruct the events that occurred. By examining the shape, size, location, and distribution of bloodstains, an analyst can uncover crucial information about the nature of the incident, from the type of weapon used to the movement of the victim and assailant.

This section serves as your comprehensive resource for understanding the science of BPA. Here, you will find articles explaining the fundamentals of the physics of blood flight and how to differentiate between various patterns like impact spatter, passive drops, and transfer stains. We provide practical guides on crucial techniques, such as calculating the Angle of Impact, which helps determine the origin of a blood source.
