Summary:Bloodstain pattern analysis can be an important investigative aspect to solving crimes involving bloodletting events. Swipe patterns on hard, nonporous surfaces have been the subject of numerous previous studies. Swipe patterns on fabrics have been less studied and are often more complicated because of wicking, backing materials, previous laundering cycles, and other factors. This study was conducted to ascertain whether distinct repeatable characteristics are observable from unassisted viewing and under microscopic view that would provide knowledge of the directional component of the swiping action. Several observable characteristics were identified that showed that the direction of swipes on fabrics could be determined with fairly high accuracy.
