The case shocked Nanjing, and Nanjing police invested a lot of police force to investigate in many ways, but there was no breakthrough.
With the progress of social science and technology, various scientific and technological means have played a huge role in solving crimes, which is one of the reasons why major cases can be solved quickly. Secondly, major cases have great social harm and bad influence, and leaders attach importance to them. People have economic security.
Extended data:
DNA identification technology and computer fingerprint automatic identification, both of which rely on the remarkable high-tech in the fields of biotechnology and computer science and technology, have become new means to solve crimes and extraordinarily serious cases, and are the most revolutionary development and breakthrough in the field of criminal investigation in recent years.
For example, DNA identification technology, a new scientific achievement, has been well used in material evidence identification technology, which has enabled us to solve many extraordinarily serious cases and also enabled many extremely important cases to identify whether the suspects are criminals according to this technology.
The rapid development of computer has also greatly changed the identification technology of "fingerprint" as the first evidence to solve the case. Many cities have established computer automatic identification systems, thus greatly improving the detection rate.
It can be seen that the progress of science and technology promotes the development of our material identification technology. At the same time, it plays an increasingly prominent role in solving crimes.
