lets decreases. An object moving at more than 100 feet (30.4 meters) per
second when it hits the victim causes high-energy spatter. Blood droplets
created by high-energy spatter are usually one millimeter in diameter or
smaller. This sort of spatter is commonly associated with gunshot wounds
and bomb blasts because of the high speed needed to create them. Most
other objects just do not move that fast. Image 8 is a picture of the blood-
spatter stain left when a bullet passed through a victim. The individual
droplets are very small. An inspection of the shape of the droplets indicates
the spatter flew directly onto the surface in the picture.
An object traveling between five- and twenty-five feet (between 1.5 and
7.6 meters) per second when it hits an individual causes medium-impact
