学习新刑事诉讼法后结合一起杀人抛尸案中相关证据存在问题的反思,旨在为法医现场勘查及物证提取提供参考。现在很多现场定罪的证据是很充分的,但因为关健证据之间有矛盾,排除不了,最后也判不了死刑。随着新刑诉法的实施,这就给我们从事现场勘验的法医和痕迹人员以及侦查人员提出了更高的要求。笔者认为可以对重要物证、书证从提取、固定、程序、关联性、保存等方面下功夫,把案件做成铁案。 After studying the new Criminal Procedural Law combined with a murder case of the corpse of evidence in the review of the existing problems, aimed at forensic site investigation and evidence extraction provide a reference. At present, there is ample evidence for the conviction on the scene, but because of the contradiction between the key evidences, it can not be ruled out and the death penalty can not be finalized. With the implementation of the new Criminal Procedure Law, this has put forward even higher demands on forensic and trace workers and investigators who conducted on-site inspections. I believe that the important material evidence, documentary evidence from the extraction, fixing, procedures, relevance, preservation and other efforts, the case made of iron case.
