The Application Of Mathematics In The Criminal Investigation

Mathematics as a human society of knowledge in a field of knowledge, not only play a huge role in physics, astronomy, but also in the field of social sciences such as economics, history, politics, and so on. In the article, I focuses on the Mathematical Applications in Criminal Investigation. Show that this discipline is not just a stand-alone, single discipline, and it Combined with the Criminalistics, become a criminal investigation methods.Firstly, in the first section, I verify the possibility and necessity of mathematical applications in criminal investigation, provide theoretical support for mathematics can be applied to the field of crime Criminal Investigation.Secondly, in the second section, I introduce several applications of mathematics in the criminal investigation, and describe the types of applications of mathematics in the criminal investigation process as well as specific operation through real-world examples and simulated case, we can find the huge value of the mathematical applications in criminal investigation.This part is the most important part of this article, three cases were cited:The first case relates to reality comic means of criminal investigation of cases, mathematical methods in detecting such cases investigators, saving a lot of man power costs and time costs for law enforcement agencies; The second case relates to a real case, about how to determine the suspects of criminal suspects, and mathematics through its operation, to help law enforcement agencies to decide ultimately whether to arrest the suspects and censorship increased persuasive evidence; The third case is about reality may encounter a situation, is to hunt down fugitives, mathematical methods provided here can help law enforcement agencies to find fugitive criminals in a very short period of time, do not need to invest a lot of man power the city raids, greatly improving the accuracy.Finally, in the third section, I give a brief description of the development situation of the country at the moment, in this regard, and the use of penetration, and why the field of China’s Criminal Investigation in the application of mathematical methods to lag behind foreign reasons, further to find a way to solve this kind of problem for China’s successful use of mathematics to find support.With this article, we can recognize mathematics as a tool of criminal investigation when it is fully applied to the criminal investigation work which, not as exists between the two areas as people think an unbreakable barriers. Between the combination of their respective areas have opened up a new path, playing enrich each discipline system, and a very practical composite disciplines, so we should pay more to learn and use.
