Bloodstain pattern analysis training videos
These short training videos demonstrate practical bloodstain pattern analysis methods used in real-world crime scene investigations. For example, the demonstrations show how stain size, distribution, directionality, and scene context can affect interpretation.

Explosive force can disperse liquid blood into fine droplets and produce complex impact patterns on nearby surfaces. However, interpretation should be grounded in the overall scene context and the pattern’s features. Therefore, when the staining is suitable for analysis, the evidence may support distinctions such as forward spatter versus backspatter.
Stain size in impact patterns can correlate with the force applied to a liquid blood source, but droplet size alone does not identify the mechanism. A reliable interpretation considers the suspected object/event dynamics and whether the pattern contains sufficient characteristics to support an area-of-origin analysis.
Individual bloodstains can range from circular to elliptical, and their shape reflects the angle at which blood impacts a surface. When enough suitable stains are present, impact-angle interpretation can be correlated across the pattern to support an area-of-origin determination.
Cast-off patterns are linear to semi-linear bloodstain trails—sometimes with slight curvature—formed when blood is released from an object in motion. They commonly result from swinging movements of a blood-bearing object, such as a hammer, pipe, or hand.
