Forensic Fiber Analysis
Fibers are considered a form of trace evidence that can be transferred from the clothing of a suspect to the clothing of a victim during the commission of a crime. Textile fibres can be transferred from rugs or blankets, between individuals, between and individual and an object or between two objects.
Locards Exchange therory:- Put forward by Locard states that with contact between two items, there will always be an exchange.. This is the basis of trace evidence collection at a crime scene.
Direct or primary transfer:- Transfer from fibre source such as carpet furnature etc
Secondary transfer:- Transfer of fibres from clothing of suspect to victim
Unfortunately fibres are not alwways transfered. Some fabric types donot shed fibres well and some fabrics do not hold or retain fibres.
With this in mind it is worth considering
i) Fabric construction and the fibre composition. ii) Force and duration of contact. iii) Damage to clothing
