Medium-velocity blood spatter patterns are typically produced by a forceful impact, such as a beating or stabbing. These types of incidents usually generate blood patterns that range in size from small droplets to larger stains, often caused by the kinetic energy imparted during the act. The force involved in such violent actions creates a distinct spatter pattern characterized by numerous droplets that can show directionality and variability in size due to the manner in which the blood is expelled.

Additionally, the nature of medium-velocity spatter is crucial in forensic investigations as it can help forensic analysts determine the type of mechanism that resulted in the bloodshed, distinguishing these patterns from those resulting from high-velocity sources like gunshots, or low-velocity sources, such as blood dripping from a height. Each of these scenarios produces different patterns, aiding investigators in reconstructing events leading up to the bloodshed.
