bloodstain pattern analysis
Bloodstain pattern analysis (BPA) is a forensic tool used to interpret the physical characteristics of bloodstains at a crime scene. By studying the size, shape, distribution, and location of blood patterns, experts can infer details about the events that occurred, such as the position of the victim and attacker during an incident, the type of weapon used, or the number of blows delivered. BPA helps reconstruct the sequence of events in violent crimes, providing crucial insights for law enforcement and legal proceedings. It combines knowledge from physics, biology, and criminalistics to enhance understanding of crime scenes.
