Blood+Article+AF

you can determine the direction the blood was traveling, the angle of impact, and the point of origin of the blood blood-spatter patterns can help determine the manner of death, based on the blood velocity blood is a mixture of blood cells and plasma -gravity acts on blood pulling it down, the blood drop has a tendency to become longer than it is wide as a result of gravity -small secondary droplets-satellites -size and shape of blood droplets help identify the direction from which the blood originated -spatter patterns help investigators determine type of wound -circular drop of blood the blood fell straight down (90-degree angle of impact) -blood dripping from a wound -point of impact may appear to be darker and wider than the rest of the drop of blood spatter -the tail points in the direction the blood was moving -the location of the blood source can be determined if there are at least tow drops of blood spatter -by drawing straight lines down the long axis of the blood spatter and noting wehre the lines intersect (lines of convergence) -source of blood where the lines meet -
