目的:提高残缺足迹的利用率,从残缺足迹的外延中重建特征,挖掘深层次的现场信息,提高破案率。方法:犯罪现场重建理论为基础,依据残缺足迹成痕机理及其变化规律,参照各种鞋底花纹的设计制作特点,形成逻辑推理和科学技术方法。结果:结合办案实践,就现场足迹的充分利用,重建残缺足迹的外延特征破获案件。结论:对利用残缺足迹的现场勘查和利用足迹外延特征重建现场提供了可供参考的方法。
OBJECTIVE: To improve the utilization rate of incomplete footprints, to reconstruct the features from the incompleteness of footprints, to tap deeper field information and improve the detection rate. Methods: On the basis of crime scene reconstruction theory, according to the mechanism of the incomplete footprints and its variation, with reference to the design features of various soles, forming logical reasoning and scientific and technological methods. Results: Combining with the practice of handling cases, the case of using the full coverage of the scene footprint and rebuilding the epitaxial feature of the incomplete footprint was solved. Conclusion: This paper provides a reference method for site reconstructing the site using incomplete footprints and using the feature of footprint extension.
