Document Summary

Bloodstain pattern analysis (bpa) is the study of the shapes, sizes, locations and distribution of bloodstains in order to provide interpretation of the physical events that gave rise to their origin. Bpa is an applied science based on the sciences such as physics, mathematics, biology and chemistry. The more acute the impact angle is the longer the ellipse. As the angel is closer to 90 degrees, the resulting stain appears more circular: bloodstain patterns are predictable and reproducible. There are basic pattern types that are reproducible and that are easily distinguished from one another in most circumstances. Bloodstain patterns can be grouped in three different categories: passive, spatter, transfer. Passive bloodstains are stains that are created or formed by the force of gravity acting alone. The following bloodstain patterns are grouped with this category: drip stain, drip trail, drip pattern, splash pattern, pool, saturation stain, flow pattern.
