The International Association of Bloodstain Pattern Analysts held its annual conference in Salt Lake City, Utah October 4-7th. There were approximately 100 attendees from across the U.S. and around the world. Ross Gardner and Tom “Grif” Griffin of Bevel, Gardner and Associates conducted two four-hour workshops about the examination and analysis of bloodstains on fabrics, including clothing. Each workshop averaged 26 participants.
During the workshop, participants were able to:
- examine fabrics with respect to impact and directional angles
- explore the use of various methods for visualization of blood especially on dark fabrics
- employ the use of the BGA decision tree for classification of bloodstain patterns on fabrics
- use magnification as a means of possibly determining contact versus spatter stains.
The last hour of the workshop allowed participants to put what they learned into practice. Each team examined a different set of clothing, all sets created under identical circumstances, to decide if the analysis supported or refuted a suspect's statement.
This workshop is a small portion of the BGA course dealing with BPA on fabrics. More information on full BGA courses can be found here.
