一、技术勘查事实认定针对一部分现场具备限定条件的案件,可通过现场勘查,临场对案犯作案过程中所造成的某些关键性事实做出事实认定,缩小侦察范围,明确嫌疑目标,达到技术破案目的。事实认定所检验研究的对象是案犯所侵害的客体和现场能够反映犯罪情况的痕迹与物证,具有不需要真实的嫌疑人和嫌疑物体作为比对样本的特点。因此,在案件的初动侦察阶段,它可以起到发现线索,判定案件性质,甚至直接揭示犯罪真实情况,引导案件侦破的实效。事实认定内容主要包括:□伪造与伪装现场的勘查与认定。□案件性质的认定。□对案件中某一具体问题的事实认定。如对作案人某些生理特征的认定等。□对现场所反映的因果关系的事实认定。如犯罪的动机、目的等。在事实认定过程中应注意掌握,必须要以对现场痕迹物证勘验的结果为依据,在案件具体的限定条件下加以认定,排斥带有超前性质的分析与推理,避免失误。
I. Confirmation of Technical Investigation According to the fact that some of the cases with limited conditions on the scene can be identified through on-the-spot investigation, some key facts caused in the process of committing the crime are spotted, the scope of reconnaissance is narrowed, the target of suspicion is clear, purpose. Facts determine that the object of investigation and study is that the offender infringed on the scene and the scene can reflect the traces of the crime and physical evidence, with no need for real suspects and suspects as a comparison of the characteristics of the sample. Therefore, during the initial reconnaissance stage of the case, it can play a clue to find out the nature of the case and even reveal the real situation of the crime directly to guide the detection of the actual effect of the case. Facts found that the contents include: □ forged and camouflaged on-site exploration and identification. □ the nature of the case. □ Facts about a specific issue in the case. Such as the identification of some physical characteristics of the perpetrator. □ Confirmation of the causal relationship reflected in the scene. Such as the motive of crime, purpose and so on. In the course of confirming the facts, attention must be paid to the fact that it must be based on the results of the on-the-spot evidence verification and be identified under specific conditions of the case, excluding analysis and reasoning with advanced nature to avoid mistakes.
