Unraveling the Secrets: Characteristics of Bloodstains

Abstract

Dharam Pal

Bloodstain patterns are valuable forensic evidence that can provide crucial insights into a crime scene. By examining the size, shape, distribution, and characteristics of bloodstains, forensic experts can reconstruct events, determine the type of weapon used, identify the number of blows or shots, and even establish the relative positions of individuals involved. When blood is shed, it forms unique patterns based on factors such as the velocity and angle at which it impacts a surface, the texture of the surface, and the volume of blood present. Different types of bloodstain patterns include spatter, splatter, cast-off, arterial spurts, and passive drops.
