Fiber Evidence: Laboratory Methods and Observations from Casework

Abstract

Abstract Simple, step-by-step methods are described for developing fibers as evidence. The methods involve recovery of adherent fibers from the surfaces of textile articles with a readily fashioned adhesive rolling device, systematic search of the recovered fibers, segregation, characterization, and comparison. Also described are methods for photomicrographic recording. The methods were developed from experience to meet the practical needs of a forensic science laboratory worker. Observations drawn from case experience are given and case illustrations are described.
