随着犯罪嫌疑人反侦查能力的提高,加之现场客体的多样性、复杂性以及手印保存条件的限制等,使得其在实际应用中出现了不同程度的困难。但只要作案人步入犯罪现场就会留下足迹,因此对于足迹的研究利用,给案情分析、作案人数的分析、作案手段的分析和后期侦查方向的确定提供了依据,为澄清案件事实和破案提供了有利证据。在犯罪现场,运动鞋的出现率是比较高的,对运动鞋鞋底足迹特征的稳定性及产生原因的研究,其重要性是不言而喻的。
With the improvement of anti-detection ability of criminal suspects, combined with the variety and complexity of on-site objects and the restriction of handprint preservation conditions, difficulties have appeared in different levels of practical application. However, as long as the criminals walked into the crime scene, they would leave footprints. Therefore, the research on footprints provided the basis for the analysis of the case, the analysis of the number of committing the crime, the analysis of the means of committing the crime and the determination of the direction of the later investigation. Provided favorable evidence. At the crime scene, the appearance of sports shoes is relatively high. The importance of the research on the stability of the characteristics of the sports shoes sole and the reasons for their occurrence is self-evident.
