Following a firearm discharge, a “high-velocity” blood spatter (5) is created and often characterized by a finely spattered pattern (2). The spatter pattern is usually circular when the projectile droplet lands at right angles to the surface, and a narrow elongated pattern forms when the projectile impacts at an oblique angle (6). These larger elongated patterns may be analyzed to determine the angle of impact and origin (6,7). The distance traveled by backspatter is reported as highly variable in the literature. For example, close gunshots to the head of live calves produced backspatter between 0 and 50 cm with a maximum distance of 119 cm (7). A case study of typical gunshot wounds by Verhoff and Karger (8) involved a suicide where extensive backspatter was observed to travel up to 4.6 m. Physical experiments from shots to a bloodied sponge covered in a rigid material resulted in backspatter traveling 30–60 cm (2,5).
