IAI-Approved 40-Hour Course
Bloodstain Pattern Analysis Training
This 40-hour bloodstain pattern analysis training course is approved by the International Association for Identification (IAI) and is designed for personnel investigating violent and bloody crime scenes.
The training covers bloodstain patterns, blood spatter interpretation, event reconstruction, and sequence interpretation through lecture and hands-on practical exercises.
15 practical exercises and related subtests using animal blood
200-plus-page manual provided to each attendee

Instruction by John Calvin Gaziano, a retired police sergeant with 32 years of law enforcement experience and 24 years in crime scene investigation. While serving with the Fremont Police Department, he was an IAI-certified bloodstain pattern analyst and senior crime scene analyst. He has also been qualified as an expert in court in bloodstain pattern analysis and crime scene investigation.

Explosive force can disperse liquid blood into fine droplets and produce complex impact patterns on nearby surfaces. Interpretation should be grounded in overall scene context and the pattern’s features and may help distinguish forward blood spatter from backspatter when the staining is suitable for analysis.
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 or event dynamics and whether the pattern contains sufficient characteristics to support 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.

Bloodstains and bloodstain patterns
A quick visual reference to the bloodstain patterns and blood spatter patterns commonly evaluated in casework.
Examples include cast-off, drip trails, transfer and wipe patterns, projected and impact patterns, voids, saturation stains, and altered patterns.
Microscopy in bloodstain analysis
Microscopy can help evaluate fine bloodstains on fabric and support distinctions such as transfer versus blood spatter when pattern features are subtle. Findings are interpreted in the context of the full case record and documented for clear reporting.
