紧紧围绕案件的特点,确定勘查的重点谋财害命案件中,犯罪分子的目的是获取财物,杀人是为了达到目的而采取的一种犯罪手段,这是谋财害命案件有别于其他杀人案件的根本点。同时,从作案手段上看,谋财害命案件又往往兼有盗窃案或抢劫案的特点。所以,在现场勘查中要抓住这些特点,紧紧追寻罪犯活动的轨迹,确定现场勘查的重点。做好中心现场的勘查,对特殊痕迹进行分析研究罪犯要进入中心现场时,就要排除在进口上的障碍。这些障碍如窗栅、铁门等往往牢度高、强度大;因此罪犯所做的动作多、幅度大,最容易留下犯罪痕迹(工具痕迹),这也就是我们中心现场的勘查重点。例如1994年6月14日发生在上海市吴兴路270弄1号3002室的盗窃杀人案,罪犯确定了厨房窗子未关、位置离电梯远,离楼梯近的3002室为作案目标后,即利用自制的特殊工具(长一市尺左右,顶端开有凹槽的自来水管),将厨房的扁铁窗栅扳断两根,后钻窗进入室内作案。现场勘查时,我们获取了窗栅上的工具痕迹以及罪犯留于室内的蒂婀多娜鞋
Tightly around the characteristics of the case, to determine the focus of the investigation of murder and fortuitous cases of murder, the purpose of criminals to obtain property, murder is to achieve the purpose of a criminal means, which is different from other murder cases The basic point of a murder case. At the same time, from the point of view of modus operandi, the cases of murder and fortune often have the characteristics of theft or robbery. Therefore, we should seize these characteristics in the scene investigation, closely follow the trajectory of criminal activities, to determine the focus of on-site exploration. Do a good job at the scene of the center of the investigation, the special traces Analysis of criminals to enter the center scene, it is necessary to rule out obstacles in the import. These barriers, such as window grilles and iron gates, tend to be fast and powerful. Therefore, criminals are more likely to act with more scope and are most likely to leave traces of crime (tool marks). This is also the focus of our on-site exploration. For example, on June 14, 1994, a robbery occurred at Room 3002, No. 1, Lane 270, Wuxing Road, Shanghai. The offender identified the kitchen window as it was not closed, its location far from the elevator, and the room 3002 near the stairs as the target of committing the crime. Homemade special tools (about a foot or so long, the top of a grooved tap water pipe), the flat iron fence in the kitchen off two, after the drill window into the indoor crime. During the on-site investigation, we obtained the tool marks on the window grilles and the pedlar shoes left by the criminals in the room
