Have you found a clue after shaking around? Liu Hongsheng didn't believe it. He has been engaged in criminal investigation for many years, and his professional qualities are the best in the entire Luzhou Criminal Police Team. I have asked where I should have seen it. I have not missed anything and found no valuable clues. He What can a layman who graduated from the political and law department see?

I was n’t a criminal investigator, but we had a plug-in. There were no witnesses at the time of the incident, but there were street trees outside the house. Shen Long just leaned on the street tree to smoke. He had already asked about the incident from the street tree. It is much easier for him to find evidence after reversing according to the case. It is no surprise that he found useful things so quickly. WWWW.SUIMENG.com

"According to the data on the dossier, the man in this family is frugal. I just looked at the ashtray. Most of the cigarette butts in the ashtray have been drawn into the filter. Only one has a long cigarette butt. This Obviously not in line with the character of the male owner, it is likely that the criminal suspect left it; according to the results of the interrogation, all the suspects we find now deny that they have ever entered this house, so as long as we can find this cigarette **** is the suspect He must be the one who left the crime. "Shen Long learned from the street tree that the suspect had smoked a cigarette before committing the crime, and the cigarette **** was thrown into the ashtray.

"How can a small cigarette **** determine who is the murderer? I remember that these criminal suspects all have the habit of smoking. This is not a murder weapon, and there are blood stains on the criminal suspect." Liu Hongsheng still did not understand. Even if the cigarette **** was really left by the criminal suspect, there is no way to convict him through this. He thought about it and asked, "Are you using this detail to review the criminal suspects again? Take some measures to make them plead guilty?"

In any case, Shen Long also found clues that he did not find, and Liu Hongsheng's tone changed unconsciously. For an old criminal like him, those with skill are worthy of respect.

"No, let's not deal with those illegal things." Shen Long knew what he meant by the measures. Sometimes the Criminal Police Force was rushed and it was normal to engage in actions such as forced confession. This approach also has certain effects. However, it is easy to create wrong, false and wrong cases, and Shen Long is not willing to take it.

What's more, this method is not in line with the rules. Other people doing this may still open one eye and close one eye. If he dares to do it, Li Mingjian will take the opportunity to drive him away. Not only will this case be solved, but also We must use absolutely legal methods to break.

"You go back to pack things, and tomorrow I will go to Shenghai with me for a business trip. I may have to stay in Shenghai for two or three days." Shen Long lowered his head into the car and said to Liu Hongsheng.

"Why do you want to go to Shenghai?" Liu Hongsheng was even more ignorant this time. Has the real murderer been controlled by Shenghai Public Security Bureau? This time, the criminals were taken back to Luzhou?

"You will know when you go." Shen Long did not disclose more information. He still has no idea of ​​Liu Hongsheng's details. He can't guarantee that telling him the truth will cause any accidents.

Back in the bureau and told Li Mingjian that he was going to Shenghai on a business trip, Li Mingjian immediately agreed. He didn't think Shen Long had to go to Shenghai at this time to solve the case. I wish he could stay in Shenghai for as long as possible. As soon as the time limit for the 72 major cases has arrived, it is time for accountability. Before that, it is definitely not conducive to solving the case if he wants to leave Luzhou City.

I went down to make a few calls, made some preparations, went back to the dormitory to rest for one night, took Liu Hongsheng to the train to Shenghai the next afternoon, slept in the hard sleeper for one night, and arrived on the third morning Shenghai.

"Captain Qi, here!" From the exit, he saw Qin Siyuan waiting outside, beside him was a police officer in a police uniform.

"Come, let me introduce to you, this is Comrade Qi Tongwei, the commander of the Luzhou Criminal Police Detachment, and Qi Team. This is Officer Lu Husheng of the Shenghai Public Security Bureau." Qin Siyuan introduced them.

"I have long heard of Captain Qi's name, and I am glad to meet you." Lu Husheng shook hands with him enthusiastically. The title of first-class hero is still very popular in the system.

Shen Long also introduced Qin Siyuan's identity to Liu Hongsheng, and then the four people got on the police car brought by Lu Husheng; Qin Siyuan was informed by Shen Long that what he had to do this time was extremely newsworthy, and he also knew that in the system To work inside, you must not only know how to make achievements, but also determine the attribution of the work, so as not to be robbed by others.

If you break the case silently, it is difficult to ensure that Li Mingjian will not give credit to others. It will be different if accompanied by Qin Siyuan. When the time comes, an article will be published in the "Public Security Newsletter", and the credit will be solid. .

"Qi team, shall we go to the guest house to rest first, or?" Lu Husheng asked as he started the car.

"Go directly to the DNA laboratory, do the business first." Shen Long replied, his purpose of coming to Shenghai this time is to use DNA detection technology to determine who the criminal murderer is. At present, there is no DNA identification technology in China. Large-scale application in criminal investigation, only the public security system in Shenghai and other three places has a DNA laboratory, so Shen Long will only make a trip ~ www.wuxiaspot.com ~ What is this DNA laboratory doing? "Liu Hongsheng was confused.

"This is a very advanced technology and won the Nobel Prize. The human chromosome is composed of DNA. Each human cell has a pair (46) pairs of chromosomes, and the human body has about 0 billion nucleotides. It constitutes the entire life chromosome system, and the exchange and combination before the formation of the germ-colonial cells are random; if they are not identical twins, no two people in the world have exactly the same sequence of 0 billion nucleotides. It is the theoretical basis of DNA comparison and identification. "This detail is what Shen Long looked from an online novel called" Han Police Officer ", but I did not expect it to come in handy here.

"The cigarette **** contains the smoker's saliva and oral epithelial cells, which can be compared with the suspect's hair to determine the identity of the smoker." Shen Long took out the evidence bag. "As early as 1984, the British used The DNA technology has cracked a **** murder case. This technology is booming in Western developed countries and is widely used in criminal investigations. There are cases of DNA identification in the United States and the United Kingdom. The Shenghai Public Security Bureau has just established a DNA laboratory. Do this test. "

"Is there such a powerful high-tech?" Liu Hongsheng, who graduated from technical secondary school, opened his mouth wide. Some of what Shen Long said just now was too mysterious, which is beyond his understanding.
