并案侦察作为一种侦破途径,目前已在刑事侦察的实践中获得广泛应用。它能使许多疑难案件迎刃而解。它的难点就在于如何确定两个乃至数个形式上独立的案件系同一人或同一伙人所为。这是并案侦察的前提。实际工作中,我们往往是从这三个方面制定的:①痕迹物证的同一性;②作案手段的内在联系;③作案时间、作案地点、袭击目标的类似性。除了痕迹物证的同一性可作独立的直接认定依据外(但这种情况并不多见),后两者都只能是间接认定依据。比较而言,作案时间、作案地点、袭击目标类似性的依据作用更逊与作案手段的内在联系。因为作案手段与罪犯具有更直接的联系。罪犯或犯罪团伙的作案经验一旦形成,其作案手段就有了一定的稳固性。这种稳固性反映在他 Reconnaissance case as a detection method, has been widely used in the practice of criminal reconnaissance. It can solve many difficult cases. The challenge is how to identify two or even several formally independent cases as belonging to the same or the same group of people. This is the premise of reconnaissance. In practical work, we often formulate the following three aspects: ① identity of trace evidences; ② internal connection of modus operandi; ③ the time of committing the crime, the place of committing the crime and the similarities of attacking the target. In addition to the identity of trace evidence can be used as an independent basis for direct recognition (but this is rare), the latter two can only be indirectly recognized. In comparison, the basis of the time of committing the crime, the place of committing the crime, the similarity of the target of the attack is less effective than the intrinsic link of the means of committing the crime. Because of the means of committing crimes and criminals have a more direct link. Once a criminals or criminal gangs experience the crime, once formed, its means of crime have a certain degree of stability. This stability is reflected in him
