【摘要】：长期以来,警犬鉴别屡屡用于刑事侦查领域,是侦查人员破案的好帮手,但在实践中,警犬鉴别能否作为法庭证据使用,在法学界颇具争议。笔者认为,从证据的合法性、客观性、科学性等方面来看,警犬鉴别尚不具备证据资格,只能作为一种侦查手段使用。DNA鉴定在证据学中被称作“证据之王”,然而,DNA鉴定在某些情况下并不能百分之百地证实案件情况,更有甚者得出一个模棱两可的结论,因此,司法人员在办案时需持审慎的态度对待DNA鉴定的证明力。确定行为人有罪,须全案的证据达到“确实充分”的证明标准,证据所证实的事实没有疑点,得出唯一性结论,形成闭合的证据链条,否则只能作出“疑罪从无”的判决。本文以徐辉强奸杀人案为例,着重分析、探讨该案的争议证据问题—警犬鉴别、DNA鉴定、证明标准。笔者试图通过对徐辉案焦点问题的分析,进一步反思该案背后的问题:司法人员在实践中应当细致深入地审查证据的证据能力及证明力,各项证据环环相扣地加以印证才能防止错案的产生;当面对证据不足的疑罪案件时,司法人员应当秉承“无罪推定”的司法理念,坚持疑罪从无。
[Abstract]:For a long time, police dog identification is often used in the field of criminal investigation, it is a good helper for investigators to solve cases, but in practice, whether police dog identification can be used as court evidence is controversial in the field of law. In the author's opinion, from the aspects of legitimacy, objectivity and scientific nature of evidence, police dog identification is not qualified as evidence, and can only be called "king of evidence" in evidence science by using .DNA identification as a means of investigation. However, in some cases, the case can not be confirmed 100% by DNA identification, and even an ambiguous conclusion can be reached. Therefore, the judicial personnel should treat the proof of DNA identification with caution when handling the case. To determine the perpetrator's guilt, the evidence in the whole case must meet the proof standard of "true sufficiency", and the facts proved by the evidence have no doubt, so that the conclusion of uniqueness is reached, and a closed chain of evidence is formed, otherwise, the judgment of "no doubt crime" can only be made. Taking the case of Xu Hui rape homicide as an example, this paper focuses on the analysis of the controversial evidence in this case-the identification of police dogs and the standard of proof. Through the analysis of the focus of Xu Hui case, the author tries to reflect on the problems behind the case: the judicial personnel should carefully and deeply examine the evidence ability and power of proof in practice. In order to prevent the occurrence of the wrong case, the judicial personnel should uphold the judicial idea of "presumption of innocence" and insist that the suspected crime should never be committed in the face of the suspect case with insufficient evidence.
