secondary blood splatter

Secondary blood splatter occurs when blood that's already been projected or spilled onto a surface causes additional droplets to disperse upon contact. For example, when a blood-covered surface hits or strikes another object, small blood droplets can break off and scatter outward. This pattern helps investigators understand the movement and direction of blood during a violent event. Secondary splatter often appears as smaller droplets surrounding or near the initial bloodstains and provides clues about the force and angle of impact. Analyzing these patterns helps reconstruct the sequence of events in a crime or accident involving bloodshed.
