Blood spatter analysis is a forensic technique used to study the patterns of bloodstains at a crime scene. By examining the size, shape, and distribution of blood droplets, experts can determine the type of injury, the position of the victim, and the direction of the blood's movement. This information helps reconstruct the events that occurred during a violent incident. The analysis involves various factors, including the angle of impact and the surface texture where the blood landed. Investigators use this data to create a clearer picture of the crime, aiding in the identification of suspects and understanding the sequence of events.
