通过现场勘查,就是要查清事件的性质,即研究和了解犯罪分子作案情况、作案动机和手段;研究和了解犯罪分子本人的特点和特征;发现和提取犯罪分子作案遗留的痕迹、物证;为侦查破案提供各方面的犯罪信息。侦查人员依靠这些犯罪信息,“再现犯罪”,确定侦查范围,制定侦查计划,采取侦查措施,进行侦查破案。  相似文献

“四战”对刑事技术和侦查工作提出了新的要求,现场勘查工作还存在如现场勘查不到位、现场勘查指挥不力、信息化手段运用不充分、侦查员与技术员缺乏沟通等诸多问题,强化现场勘查工作是适应“四战”需要。  相似文献

犯罪现场层次是犯罪现场存在表现及其被侦查人员认知的程度。犯罪现场是由犯罪时间、犯罪空间、犯罪嫌疑人条件、犯罪痕迹物证、犯罪活动过程、犯罪心理、犯罪证据等各种层次构成的复合体。研究犯罪现场层次论也是研究犯罪现场构成要素的存在及其在不同层面的联系。犯罪现场层次也是研究和揭示犯罪现场存在的一种认知。研究犯罪现场层次问题,也可以使我们对犯罪现场状况及其勘查工作质量给以程度判定。  相似文献

现场勘查工作对刑事案件的侦破起着十分重要的作用,随着法制化进程的不断推进,对现场勘查各环节的规范化要求日益提高。当前各级公安机关都十分重视犯罪现场勘查仪器、设备的投入,然而硬件的完善只能为做好犯罪现场勘查工作提供技术支持,因此加强对犯罪现场勘查的环节控制,提出有针对性的解决对策就显得十分重要。  相似文献

模拟画像是实现对犯罪嫌疑人相貌视觉形象刻画的技术手段。模拟画像应成为犯罪现场勘查工作的一项基本的规范性内容。模拟画像技术要求勘查现场的应解决的主要问题和勘查重点有:(一)寻找、发现目击犯罪嫌疑人的受害人和其他证人;(二)访问、记录目击者对犯罪嫌疑人的感知过程;(三)提取、记录目击者对犯罪嫌疑人体貌特征的记忆;(四)对目击者的调查访问要讲究技巧。模拟画像在侦查中运用应注意的问题:(一)相貌学知识非常重要;(二)必须注意目击者的个体差异对模拟画像的影响;(三)证人之间不要有互相影响的情况;(四)对重要目击者的保护;(五)必要时重新进行模拟画像;(六)划定侦查范围非常重要;(七)可以确定犯罪嫌疑人,不能否定犯罪嫌疑人。  相似文献

This study tests the effect of three common oxidizing cleaners on the ability of the Bluestar Forensic® presumptive test for blood to identify the presence of blood on ceramic tile after cleaning. The cleaners tested were Lysol®, OxiClean®, and Arm & Hammer®. This study also tested which cleaner was the most effective at removing blood, measured by the intensity of chemiluminescence, which was quantified using RGB values in ImageJ. A “hasty” 1‐min cleaning of a blood droplet was simulated using the three cleaners. The chemiluminescence of the Bluestar® reactions after cleaning the blood‐treated region was compared to an untreated region of the same tile for each cleaner, as well as to the treated regions of tiles between the three cleaners. Results indicate that none of the three cleaners removed all of the blood (all < 0.001) and that Lysol® removed more blood compared to the OxiClean® and Arm & Hammer®.  相似文献

近年来,面对国内非法偷猎、走私野生动物刑事案件增幅较大的现状,如何提高案件现场勘查水平是我国森林公安机关必须解决的最迫切的问题。由于野生动物案件现场勘查的对象不同,在证据固定的方法上有其特殊性,因此,需要制定必备的技术操作规范。通过对现场勘查、物证提取和保存等关键环节的研究,提出可作为重要参考依据的技术标准。  相似文献

犯罪现场概念是一个随着社会发展而不断演化的概念.狭义的犯罪现场概念是与犯罪行为有关的场所及载体.广义的犯罪现场概念是与犯罪行为有关的人、物、时、空存在及其内在联系的总和.大数据时代的到来,让我们对犯罪现场广义概念的认知更加具有现实层面的应用意义.树立与大数据模式相应的犯罪现场观,通过各种与犯罪现场构成要素及其联系相关数据库的发掘与应用,可以带来侦查破案思维与工作模式的大变革.  相似文献

Management of a crime is the process of ensuring accurate and effective collection and preservation of physical evidence. Forensic botany can provide significant supporting evidences during criminal investigations. The aim of this study is to demonstrate the importance of forensic botany in the crime scene. We reported a case of a woman affected by dementia who had disappeared from nursing care and was found dead near the banks of a river that flowed under a railroad. Two possible ways of access to crime scene were identified and denominated “Path A” and “Path B.” Both types of soil and plants were identified. Botanical survey was performed. Some samples of Xanthium Orientalis subsp. Italicum were identified. The fall of woman resulted in external injuries and vertebral fracture at autopsy. The botanical evidence is important when crime scene and autopsy findings are not sufficient to define the dynamics and the modality of death.  相似文献

Bloodstain photography is important in forensic applications, especially for bloodstain pattern analysis. This study compares the enhancement effect of bloodstain photography using three different types of light source: fluorescent white light, near‐ultraviolet (UV) light‐emitting diode (LED) light, and 410 nm LED light. Randomized complete block designs were implemented to identify the lighting that would statistically produce the best enhancement results for bloodstains on different types of surfaces. Bloodstain samples were prepared on white cotton, brown carpet, tar road, and wood. These samples were photographed in darkroom conditions using a Canon EOS 50D digital SLR camera, with Canon EFS 60 mm f/2.8 Macro USM lens. Two‐way analysis of variance and Fisher's least significant difference test were used to analyze the contrast of the images. The statistical analysis showed that 410 nm light is the best among the tested lights for enhancing bloodstains on the tested surfaces, where the contrast of bloodstain to background was the highest.  相似文献

A large body of research has described the influence of context information on forensic decision‐making. In this study, we examined the effect of context information on the search for and selection of traces by students (N = 36) and crime scene investigators (N = 58). Participants investigated an ambiguous mock crime scene and received prior information indicating suicide, a violent death or no information. Participants described their impression of the scene and wrote down which traces they wanted to secure. Results showed that context information impacted first impression of the scene and crime scene behavior, namely number of traces secured. Participants in the murder condition secured most traces. Furthermore, the students secured more crime‐related traces. Students were more confident in their first impression. This study does not indicate that experts outperform novices. We therefore argue for proper training on cognitive processes as an integral part of all forensic education.  相似文献

Currently, a series of promising new tools are under development that will enable crime scene investigators (CSIs) to analyze traces in situ during the crime scene investigation or enable them to detect blood and provide information on the age of blood. An experiment is conducted with thirty CSIs investigating a violent robbery at a mock crime scene to study the influence of such technologies on the perception and interpretation of traces during the first phase of the investigation. Results show that in their search for traces, CSIs are not directed by the availability of technologies, which is a reassuring finding. Qualitative findings suggest that CSIs are generally more focused on analyzing perpetrator traces than on reconstructing the event. A focus on perpetrator traces might become a risk when other crime‐related traces are overlooked, and when analyzed traces are in fact not crime‐related and in consequence lead to the identification of innocent suspects.  相似文献
