"Our laboratory has just been established, and it has not yet begun to be applied to formal investigation work, so Team Qi's news is really well-informed." Lu Husheng interjected with a smile, because it was a newly established department, they also wanted to make achievements as soon as possible, but DNA testing technology is still a new thing in China, and the local police in Shenghai are not very trusted, and they also lack cases.

"I think that DNA testing technology is the future development direction of criminal investigation, in the past criminal cases, case-handling personnel have been gullible confession of false evidence, and even in pursuit of confession to use torture and other illegal means, and DNA testing technology can reduce the importance of confession, and even achieve zero confession case, can help us avoid the use of these illegal means, but also reduce the occurrence of unjust, false and wrongful cases, is of great significance." Half of these words were said to Qin Siyuan.

"Zero confession case? That's an interesting statement. Qin Siyuan really won Shen Long's full set, and hurriedly took out his notebook to write down what Shen Long just said, he has been doing publicity and reporting work in the public security system for many years, and he has also been in contact with torture to extract confessions and unjust, false and wrongful cases.

Although there are extenuating circumstances, but illegal means are illegal means, there is no way to put it on the table, some old oilers also deliberately provoke the case-handling personnel to torture, and then take the opportunity to attack the police for illegal torture to get rid of the crime, if you can really use DNA testing technology to achieve zero confession to handle the case, the existing case solving rate will definitely be greatly improved, and at the same time, this illegal means can be avoided, which is a great thing for the public security system.

"When the test results come out, you can go back to Luzhou with me and see how we use DNA technology to find evidence." Well, Qin Siyuan is already tempted.

"Team Qi is a top student of Handong University in the end, and his thinking is active." Qin Siyuan said with admiration, there was a matter of demolishing houses to break the hearts of drug traffickers, and now there is a DNA testing case, these methods are not something that ordinary people can think of, and he has begun to think about how to use this material to write a big article.

When they went to the DNA laboratory of the Shenghai Public Security Bureau, they handed over the cigarette butts, as well as the hair taken from the suspects and family members of the victims, to the experimenters for testing.

Qin Siyuan kept taking pictures with his camera, and it took some time to detect, so after taking pictures, Qin Siyuan followed Shen Long to the guest house of the Shenghai Public Security Bureau, and grabbed Shen Long to ask about the situation of the 7.23 case.

"This case was previously in charge of Officer Liu, and the suspects were all found out by him, so you can ask him about the specific situation." Shen Long doesn't mind giving some credit to his subordinates, judging from the observation in the past two days, Liu Hongsheng is a high-quality criminal policeman, and he is not a person from Li Mingjian, so he can completely take it under his own hands.

"Thank you, Team Qi." Liu Hongsheng nodded to Shen Long gratefully, he knew the weight of the "Public Security Newsletter", and Shen Long gave him the work of introducing the case, which had a heavy explanation of the role he played in this case, which meant that if the case was really solved, his name would also have the opportunity to appear in this magazine and be seen by colleagues in the national public security system.

These are not only honors, but also the capital of promotion, although Liu Hongsheng has excellent professional quality, but because his temper is too hard, he will not please his superiors, so he has not come out for a long time, and now the opportunity has finally come.

He introduced the case 1510, except for some information that must be kept secret, it can be said that he knows everything and says everything, and after listening to it, Qin Siyuan is also very emotional, "This case is really difficult to handle, if it wasn't for the Qi team to find the cigarette butt, it would really be difficult to convict the murderer." ”

Although he works in the propaganda department, he can easily judge the difficulty of this case after more contact, if it were not for the cigarette butt and no DNA testing technology, it would be really difficult to determine the murderer.

"Now we have only found a few clues, and if the test results show that the DNA on the cigarette butt is a family member of the victim, or does not match the DNA of the suspect we found, then we have to continue to look for new clues." Shen Long said modestly, in fact, with the reminder of the street tree, he was very sure who the real murderer was.

A day later, the results came in, and the test showed that the DNA left on the longest butt of the cigarette butt was exactly the same as the DNA extracted from the hair follicle of one of the suspects.

"It is true that some people saw him near the scene of the crime, but I have interrogated him several times before, and he has always denied that he had ever entered the victim's home, and now I have finally found evidence." Liu Hongsheng's face was excited, with this evidence, the next interrogation work would be much easier.

"Okay, then let's go back tonight, and re-interrogate this suspect tomorrow, and you still do the work." Qi Tongwei didn't intend to monopolize the credit, with the cigarette butt and the suggestion to put forward DNA as evidence, he had already got the lion's share, and letting Liu Hongsheng share the profit would not affect his political performance at all.

"I'll go back with you, I've already applied with the editor-in-chief to do a special report for you in the next issue." Qin Siyuan realized that this case might become another model case in the ministry, and it would be of great benefit to him if he wrote this article.

He is now looking at Shen Long more and more pleasing to the eye, since he came into contact with him, this article material is really endless.

After inviting Lu Husheng and the staff of the laboratory to have a meal, Shen Long took Liu Hongsheng and Qin Siyuan on the train back to Luzhou City, where Liu Hongsheng kept holding the materials obtained from the laboratory to look through the research.

The more he looked, the more interested he became in the application of DNA detection technology in criminal investigation work, and even asked Shen Long, "Team Qi, do you think you can set up a DNA laboratory in our Luzhou Public Security Bureau?" If there is such a laboratory, I feel that many of the cases that have been backlogged before can be solved quickly. ”

"It's not easy, now these testing equipment have to be imported from abroad, if you want to build a laboratory, you have to give one or two hundred million, and we are afraid that we can't get it." It's not a problem for you to let Shen Long get 10 or 20 million in a short period of time, it's a big deal to go to Macau, but there is no reason to use your own money for office work, but it seems that it can be ......
