Description
Technical Field
The utility model relates to the technical field of criminal investigation, in particular to a multifunctional on-site material evidence signboard.
Background
The material evidence refers to various objectively existing articles, substances, documents and traces which are related to the case according to law collection, and can be proved to be in two forms of real objects or traces by the appearance characteristics, the carried text characteristics or the substance attributes of the case through scientific identification or investigation measures. The material evidence is one of the most important forms in forensic science, has extremely high investigation and use frequency in various cases, is also an important basis in the subsequent criminal litigation stage, and is an important means for on-site reconstruction. The material evidence identification plate is an extremely important indicating tool in field reconstruction, is mainly used in a material evidence preservation stage in field investigation, plays roles in classifying, marking, warning, proving, auxiliary fixing, extracting and the like on the field material evidence, and is important equipment indispensable in evidence collection work.
The federal survey agency (Federal Bureau of Investigation, english abbreviation FBI) in the united states requires 12 steps in the field survey procedure. In the step of photographing the scene, firstly photographing the discovered material evidence, then placing a material evidence identification plate for photographing, and simultaneously recording the photographing time of the material evidence by a photographing recorder; the material evidence identification plate is listed as one of equipment in the field investigation box in China and is mainly used in the field investigation stage, but the application range and the application method of the material evidence identification plate are not specified in detail.
The field material evidence signboard developed by manufacturers in China is generally made of paper or plastic, numerals are marked on two sides of the field material evidence signboard, and right-angle scales are attached to the field material evidence signboard and can be bent into different angles. Because the current laws and regulations do not make corresponding standard specifications for the material evidence identification plate, and other manufacturers cannot fully understand the public security service, the requirements of the basic public security technology cannot be met sometimes, for example, more than hundred marks and material evidence exist on the major case site, the variety and distribution are wide, and great difficulty is caused to the on-site identification and fixing work.
Specifically, the conventional material evidence signboard has the following disadvantages:
the serial number of the material evidence identification plate is limited
At present, the serial numbers of the material evidence identification plates produced by most factories are generally 1-30 or 1-50, for example, the number of left traces and articles are more on the scene of a major criminal case in some outdoor environments, and the limited serial numbers can not meet the requirement of a fixed scene; even for the same type of trace, articles, such as a large number of drop-like blood stains, a large number of cartridge cases, there are also indistinguishable cases. Therefore, the existing methods can not meet the demands of the event and case sites far.
(II) material evidence signboard single color form
The identification plate in the site investigation box is often single-color, and can not meet the independent identification of different kinds of marks and physical evidence in the site. The trace and the article in the field are rich in variety, and the trace and the article are summarized to have the traditional trace material evidence such as hands, feet, workers, guns and the like, the physical material evidence such as a working tool and the like, and the biological material evidence containing DNA, the trace material evidence and the like. At present, the material evidence identification is only in the traditional colors of black, white, yellow and the like, and the requirement that the material evidence identification plate is utilized to know the current field environment in the later field analysis process can not be met completely.
(III) the material of the material evidence identification plate is easy to damage
For special sites, especially complex sites, explosion, fire case sites and the like in field environments, paper, plastic and other material identifiers are extremely easy to damage, and great difficulty is brought to site reconstruction.
Therefore, the field material evidence signboard is used as important equipment for classifying, marking, warning, proving and fixing the field in the field investigation, plays a role in the investigation of the case and the event field, and has important significance for standardized construction of police equipment.
