"Yu Su, you'd better look at the mop!" Niu Bing said lightly. Although he did not find any other problems with Yu Jiankun, the mere fact that Yu Jiankun came out to cheat his car was enough to show that Yu Jiankun had a problem. At this time, Yu Jiankun was just arguing and insisting on committing suicide, but he did not give Yu Jiankun much face.

"...He can also use a rag..." Yu Jiankun walked into the toilet and looked at the mop hanging on the water pipe, but his face turned red. The mop may have not been used for too long. The cloth of the mop has been minored. With a little force, the cloth on the mop will fall off. In other words, the mop cannot be used at all and the mop cannot be used. The conclusion of Zhong Xunan's diligence is no longer important, because he has no way to mop the floor. However, he is still unwilling to admit defeat. From the bottom of his heart, he is very dissatisfied with Niu Bing pressing him. For this director, he has done too much effort and work, but the result is always disappointing. Niu Bing is so furious.

The child who had not grown up had climbed up to his head, which made him not only disappointed, but angry. He had been at least twenty years of police officers, and he was better than a young boy. And he didn't really care about such a case, not only him, but also the same group of people in the criminal police team. A drug addict is a cancer of society. Such a person will die if he dies. No one takes it too seriously. Otherwise, the people in the criminal police team would not dare to ignore it. Therefore, at first, he did not take it too seriously and made a judgment in a hurry. After Niu Bing made the opposite judgment, he tried his best to prove that his judgment was correct.

"Director Yu, please go and find a rag." Niu Bing became even more rude.

"...Captain Xiao is here!" Yu Jiankun's face turned redder. He actually noticed that there was indeed a piece of rag in the room, a piece of rag that was not much bigger than a palm. If you use that piece of rag to wipe the floor, it would not be an easy task. Fortunately, at this time, Captain Xiao from the technical squadron of the Criminal Police Team rushed over and a murder case occurred. The criminal investigation personnel dared to give up and throw the case to Niu Bing. The person in charge of the inspection did not dare to be lazy. The police station did not have the ability in this area. Even if they had the ability in this area, they did not have the qualifications in this area.

"Director Yu, is this Director Niu?" Xiao Zhiqiu looked at Niu Bing more of his eyes. He had heard of Niu Bing, but had never seen Niu Bing. Niu Bing was obviously much more immature than he thought, but he couldn't understand why Captain Tao of the Criminal Police Team threw the case to Niu Bing so confidently. This was a murder case, not another case. This was the work of the Criminal Police Team. If the police station didn't ask if something happened, Tao Huanle would have an unshirkable responsibility.

"I am Niu Bing!" Niu Bing nodded.

"What did Director Niu find out..." Xiao Zhiqiu looked at Niu Bing.

"Judged by the degree of decay of the deceased body, the death time should be about two days. In addition, we found that... based on these situations, it can be basically confirmed that he killed him." Niu Bing understood that Xiao Zhiqiu didn't believe in his ability. He had experienced too much of such suspicion and had no effect at least, and his mentality had no effect. Therefore, he still briefly told Xiao Zhiqiu of what he discovered.

"I have heard that Director Niu is more skilled in on-site investigation than us professionals. I still don't believe it. I finally saw it today." Xiao Zhiqiu was a little surprised. There seemed to be nothing that Niu Bing discovered, but it was definitely not easy to find these things. Especially when he found a problem in such a short time, he came over when he received the call. It took about ten minutes for Niu Bing and the others to arrive here. The cordon outside had not been completely pulled out. It was difficult for him to find these problems in such a short time.

"Captain Xiao, I just have a little stronger eyesight, so I can't understand what to do to investigate." Niu Bing smiled and shook his head.

Next, they quickly arranged the matter and determined to kill him. It would naturally be a check on the murderer and look for witnesses as much as possible. Niu Bing also asked about the personnel of the security department. The management of the electronics factory is relatively formal, and there are also many old cadres here. Xu Guangli is obviously a person who respects the old leaders more. The management of the old family district is also in order. He also specially arranged the old comrades in the security department to be responsible for the doorman and specially arranged people to manage the place. Therefore, the order of the old family district is still relatively good.

Usually, the door is closed, and only a small door is open. Moreover, many people like to chat with the guards, or play chess, etc. The family area is full of old acquaintances, strangers, or people from society, so it is difficult to enter the family area. It can be said that it is more strict than ordinary communities. This situation makes Niu Bing feel a little relieved, at least, it makes the investigation much easier. According to the situation provided by the security department staff, the last time I saw Zhong Xunan was at dusk the day before yesterday.

However, Niu Bing did not participate in the investigation. He carefully checked around. The family area was not big. The two corner buildings were side by side, all three units. There were only half a unit in the corner. The middle of the two corner rooms was the gate, and the other side was a high wall, which was about four or five meters high, and there was a primary school outside the wall. The entire family area seemed impossible to be able to pass in. The only entrance was the gate.

"Xiao Mo, what do you think?" Niu Bing glanced at Mo Chaohong beside him and asked. Since he brought people, he naturally wanted to give Mo Chaohong some place to play.

"According to the protection situation here, it is difficult for strangers to enter here and not be discovered. Moreover, according to the investigation by Director Niu, the other party should be the place where he mopped with a mop. Therefore, the murderer should be an acquaintance, and it is likely that someone in the community committed the crime." Mo Chaohong analyzed in a low voice.

"If you were asked to investigate this case, how would you investigate?" Niu Bing continued to ask. Such a conclusion was easy to draw. Mo Chaohong had been in the criminal police team for a year, but he could not draw this conclusion, and he could not become a criminal policeman.

"I think we should look for people who have contact with Zhong Xunan, find witnesses or people who often have contact with him."

"He is a drug addict. Perhaps no one would be willing to contact him for such a person, and no one has come to report it yet. I think no one has ever contacted him. At least, no one has found out who he has contacted with these days. How should we check in this situation?" Niu Bing continued to ask.

"We should start with the motive of killing and investigate those who have conflicts with Zhong Xunan." Mo Chaohong said in a low voice.

"Yes, start with the motive of murder. If you kill someone, there must be a motive. However, do you really think you should investigate people who have conflicts with Zhong Xunan?" Niu Bing looked at Mo Chaohong.

"If you don't check for people with conflicts, then what should you check?" Mo Chaohong was a little confused.

"Think about the murder scene again." Niu Bing reminded.

"The deceased should not have had much struggle before his death, and the doors and windows were intact, and there were no suspicious signs in the room... The murderer entered the victim's house through the gate. The murderer should have a good relationship with the victim. The victim let the murderer in. But how could he not resist?" Mo Chaohong quickly figured out something. If there was a conflict, it would obviously not be easy to enter the victim's house. Moreover, the murderer could not be completely unprepared for those with conflicts, but even if he was not prepared, Zhong Xunan should have resisted and struggled a little. After all, that was killed. Before he died, he should also struggle.

"It may not be that they have a good relationship with the victim, or it may be that the murderer has the key to the victim's home. As for why Zhong Xunan did not struggle, it would be difficult for ordinary people to explain this, but he is a drug addict, which is easier to explain. After taking or injecting drugs, the entire body, head, and nerves of the person will quickly produce an explosive pleasure. Then, within two or three hours, the absorber is immersed in a semi-anthemia state!" Niu Bing explained.

"Oh, that's right!" Mo Chaohong really didn't know much about drugs. He just heard about drugs. They did not learn about drugs. When they were internship in Linshan County, the criminal police team had never encountered drug cases. The drug-related cases in Linshan were all small cases, and the police station solved it. There was no need for the criminal police team to take action. Therefore, he had never been exposed to drugs at all and had no knowledge of drugs.

"Now, what do you think should be checked?" Niu Bing continued to ask. Only by letting him think on his own can he truly learn something.

"We should focus on checking people who have something to do with him and checking his family's keys." Mo Chaohong thought for a while and said, the people in society were excluded, and acquaintances in the family area were much smaller. Except for those who were usually related to Zhong Xunan, they were those who might have the keys to Zhong Xunan's family.

"Why do you think the murderer wants to kill him?" Niu Bing continued to guide the investigation of the case, not simply investigate, but more importantly, thinking from all aspects. Only by fully thinking about the situation in all aspects, excluding what should be eliminated and what should be investigated can we find the final result.

"From his situation, there should be two situations. One is that he may often get involved or something, and the other is that he may have done something shameful, which makes people want to kill him." Mo Chaohong thought for a while and said.
