After eating overtime meals, Chen Weibin returned to the office, thinking about the tasks to be assigned at the evening meeting.

At eight o'clock in the evening, the conference room of the Criminal Investigation Detachment of the Zhongcheng District Public Security Bureau was brightly lit, and everyone arrived at the venue one after another.

Yuan Qing, deputy head of the detachment, gave a briefing on the basic facts of Zhou Yuanliang's case and briefed him on the afternoon's questioning. The interpols who attended the meeting began to speak and began to discuss.

The participants are all the backbone of the criminal investigation detachment, and they are all veteran criminal policemen for many years. Through heated debate and careful analysis, most people agreed that Zhou Yuanliang's death was more likely.

The first is the cause of death, Zhou Yuanliang died of king cobra venom. Using snake venom to kill oneself is what a fetish it must be for the deceased! A person who is ready to die, why does he need so much red tape? Moreover, Zhou Yuanliang has a net worth of tens of billions, the richest man in Miojiang, a successful businessman, and he has no fatal serious illness and no motive to commit suicide. Through the analysis of various signs, the criminal police finally came to a conclusion: Zhou Yuanliang died of murder, which is a serious criminal homicide case!

After listening to everyone's analysis, Chen Weibin nodded and said, "I think the same way." It seems that everyone has reached a consensus, so we will report to the sub-bureau according to the conclusion that he killed. ”

Chen Weibin said to Zhang Peng, the internal staff: "Zhang Peng, you immediately draft a case report, and Captain Yuan and I will take it to report to the leaders of the sub-bureau early tomorrow morning." ”

"Okay." Zhang Peng agreed.

"I thought about it for a while, from now on, the various brigades will start working immediately." Chen Weibin began to arrange the work.

"A large team investigated Zhou Yuanliang's residence to see if there were any clues, and paid attention to letting his family cooperate with us at the scene, and at the same time strengthened the investigation of Zhou Yuanliang's two sons and his wife."

The second team went to Zhou Yuanliang's company office to have a look, and at the same time asked the company's employees if Zhou Yuanliang had any abnormal situation recently. Pay special attention to ask the staff around him to learn more about Liangdong Group and Zhou Yuanliang himself. ”

The three teams immediately retrieved the surveillance video near Zhou Yuanliang's residence and paid close attention to the suspicious situation before and after Zhou Yuanliang's death. When viewing the footage, be careful and careful, and don't miss a second. ”

"The four teams searched the city for a king cobra breeding site and asked if anyone had bought snake venom. This poison is very rare and difficult to find, and the comrades of the four brigades must be patient. ”

"The Fifth Brigade strengthened contact with the communications department and retrieved Zhou Yuanliang's recent call records. Especially the call records of Zhou Yuanliang before his death, it is even more necessary to carefully investigate and find out their relationship with Zhou Yuanliang. ”

After arranging the work tasks, Chen Weibin looked at everyone and said, "Okay! Comrades for your hard work! Let's go our separate ways. ”

After the meeting ended, Chen Weibin returned to his office. There's been so much going on today, and I've never been idle, so I'm so tired. Chen Weibin reclined on the sofa, lit a cigarette, and gradually fell into deep thought.

Zhou Yuanliang's death came too suddenly, who poisoned him? Vendetta? Love killing? Money killing? Or is it another case of a wealthy family's property dispute? Zhou Yuanliang is the richest man in Miojiang City, with wide connections and great influence, this case must be the focus of social attention, and it will also be hyped on the Internet, this case must be solved! With years of experience as a criminal policeman, Chen Weibin has handled many big cases, and this time, Chen Weibin felt unprecedented pressure!

What kind of poison is king cobra venom? Chen Weibin didn't understand either, so he got up and sat on a chair and looked up relevant information on the Internet.

King cobra venom is a toxic protein containing a variety of toxic components, which can cause pathological changes in tissues and organs such as heart, liver, kidney, lung, and brain after entering the human body, and changes such as hemolysis and organ swelling. Snake venom poisoning can cause muscle paralysis, mucinous secretions to fill the airways and cause acute respiratory failure, leading to hypoxia in the body, which in turn promotes heart and brain failure and death.

King cobra venom is a special kind of poison, it is different from pesticides, the venom is into the blood of the human body to cause poisoning and death, if you just swallow the venom into the stomach, the venom will not play a toxic role to cause death, but also act as a protein in the stomach to be digested by gastric juice.

In this way, how did the snake venom enter Zhou Yuanliang's blood? During the investigation of the scene, a pinhole was found in the abdomen of the deceased. According to the deceased's eldest son, Zhou Xianquan, the deceased suffered from diabetes before his death and needed to take insulin. Could someone deliberately switch the insulin to snake venom, so that God would put Zhou Yuanliang to death without knowing it?

Thinking of this, Chen Weibin immediately dialed Yuan Qing with his mobile phone and told Yuan Qing: "Yuan Qing, I just thought of something. You inform the first and second teams, pay attention to Zhou Yuanliang's home and company, find out the remaining insulin, and report to us immediately if there is any situation. ”

Yuan Qing replied on the other end of the phone, "Okay." Notify them right away. ”

Chen Weibin flipped through the transcript of the interrogation and sorted out the conversation in the afternoon. So far, four people have been spoken.

One is Tong Xiaojin, Zhou Yuanliang's wife. What kind of relationship is there between them? Chen Weibin recalled that he did not inform Tong Xiaojin that Zhou Yuanliang died of his killing, how could she be so sensitive and immediately excuse herself. Did she know that Zhou Yuanliang was murdered?

Zhou Yuanliang's eldest son, Zhou Xianquan, is decent, seems to be an honest man, and should have feelings for his father. His performance is by nature, or is it faked. Even if he is indeed an honest man, must an honest man not sin?

That Zhou Xianqing, a slave of money, was an idler at first glance, and judging from his reaction, his father Zhou Yuanliang was far from being interested in money. This kind of person's heart has been distorted, will he kill his father and take wealth for the sake of property?

Nanny Wang Cuiping, looking frightened, can't help but give up, is she a manifestation of real emotions, or is she performing? She is responsible for a lot of Zhou Yuanliang's private life, will she be the murderer? Or was she bought to be a murderer?

Or, none of the four of them are murderers, none of them have anything to do with the case, and the real murderer is actually someone else, maybe he is hiding in the dark and watching quietly.

Or...... A series of question marks filled Chen Weibin's brain. The law is about the innocence of guilt beyond doubt, and that is the principle that judges follow when deciding cases. Chen Weibin is a police officer, and the case is still in the investigation stage, adhering to the principle that there is always a suspicion of guilt, and he does not dare to easily rule out the suspicion of any person. No wonder there is a saying in society: the police have been in office for a long time, and everyone is a criminal suspect.
