实践证明,现场勘查的好与坏、现场分析准确与否,直接关系着刑侦工作的成败。在实际工作中,一些侦察人员,甚至我们一些侦察决策领导人由于缺乏对刑事技术科学性、专业性认识,不尊重现场情况,对勘查技术人员提出的现场分析意见持有疑虑(或不相信),侧重于调查访问所得的情况或线索,致使侦察工作步入迷途,贻误了战机。发生在我市某县一起特大抢劫杀人案件就很具有代表性。1994年10月15日,西安市某县安家大队十一组曹平均一家三口被杀害于家中,并被纵火焚尸,现场遭到严重破坏。市局刑侦处技术科经全面认真的勘查现场发现提取了案犯鞋印。根据现场特点、尸体位置、变动情况和痕迹物证分布等进行综合性分析,勘查技术人员在临场分析会上提出了如下几点意见(结论):①这是一起有预谋的抢劫杀人案件;②根据案犯鞋印分析,系一人作案,案犯身高170cm左右,年龄20-25岁;③从现场环境及大门关闭情况分析,案犯从大门出入,系叫门入室,案犯与死者有某种熟人关系;④案发当晚下大雨,而且适逢停电,说明案犯居住地离现场不远,排除流窜作案;⑤现场有血手套印痕反映,说明案犯带手套作案。后根据现场勘查过程中所提取的滴落血迹检验结果证明案犯受了伤。 Practice has proved that the site survey of good and bad, on-site analysis is accurate or not, is directly related to the success of criminal investigation. In actual work, some reconnaissance officers, some of our leaders in reconnaissance and decision-making, have doubts (or do not believe) in the on-site analysis opinions of survey technicians due to their lack of scientific and professional understanding of criminal technology and lack of respect for the scene. , Focusing on the investigation of the proceeds or clues to visit, resulting in the reconnaissance work into a lost, delaying the fighters. Occurred in one of the city together with a large robbery murder case is very representative. On October 15, 1994, a group of three in the eleven groups of the Anji Brigade, a county in Xi’an, were killed at their homes and were set on fire at their homes. The scene was severely damaged. City Bureau of Criminal Investigation Department of Technology by a comprehensive and serious investigation of the scene found that the perpetrators extracted shoes. According to the characteristics of the scene, the location of the body, the changes and the distribution of the marks and evidences, the prospecting technicians put forward the following opinions (conclusions) at the spot analysis meeting: ①This is a premeditated robbery and murder case; ② according to Case analysis of shoes and India, the Department of committing the crime, the perpetrators height 170cm or so, aged 20-25 years old; ③ from the scene and the door closed the situation analysis, the perpetrators from the door, the Department called the door into the room, the offender and the deceased have some acquaintance relationship; Heavy rain occurred on the night, but also on the blackout, indicating that the offender living far away from the scene, excluding the fled to commit crimes; ⑤ on-site blood glove impressions reflect the case of committing a crime with a glove. According to the scene of the investigation during the extraction of blood test results show that the offender was injured.
