Fibre persistence on immersed garment—Influence of knitted recipient fabrics

摘要: The persistence of fibre traces is a critical factor in the evaluation findings forensic casework. Many studies have examined loss on living subjects or bodies exposed to open-air conditions but none them ever considered underwater conditions. This first part larger study focuses transferred fibres various recipient garments during an immersion/emersion process as common step all casework involving A smooth polyester garment leads weak values around 20%, while higher values, ranging between 80% and 90%, are obtained for more structured textured (cotton T-shirts, fleece acrylic pullovers). More thus less affected by closer their initial amount distribution before immersion. protruding density rough fibrous network at surface both key factors that increase value. Therefore, these should be taken into account when evaluating evidence recovered immersed bodies.
