ABSTRACT
Adequate training in bloodstain pattern interpretation includes hands-on performance of controlled laboratory experiments which duplicate the types of bloodstain patterns encountered at the scenes of violent crimes. This chapter outlines the basic laboratory experiments determine the average volume of a single drop of blood falling from the tip of a 5-ml volumetric glass pipette for reference purposes. It is recognized that the average volume of a drop of blood will vary depending upon the type of object from which it falls. The objective of this experiment to study the oval or elliptical nature of bloodstains produced by drops of blood falling onto nonhorizontal surfaces compared with blood drops falling onto a horizontal surface producing more or less circular bloodstains relative to the surface texture of the target surfaces. The objective of this experiment is to study the bloodstain patterns produced by high-velocity impact produced by gunshot.
