交通肇事案件中尼龙纤维对油漆物证检验的干扰问题研究
Research on the Interference of Nylon Fiber on Paint Evidence in Traffic Accident Cases
摘要
Abstract
Objective In traffic accident cases involving collisions between people and vehicles,paint evidence is attached to clothing fibers due to collision contact.Due to the instantaneous high temperature of the impact,some synthetic fibers will melt into the paint evidence,which will interfere in the comparison and inspection of the components of the paint attached to the clothing and the paint on the vehicle.Methods This article reports a case of a pedestrian vehicle collision traffic accident in which fibers melted into paint evidence and could not be physically separated.The interfering fibers were separated by using chemical reagent cleaning method.Results The paint attached to the clothing was suceessfully compared with the vehicle paint.Conclusion The chemical reagent cleaning method can effectively separate interfering fibers.Finally,a summary and discussion were conducted on the processing methods of paint evidence attached to clothing fibers to promote their application in investigation and case handling practices.关键词
