I don't want to solve the case when I'm a little policeman.

Chapter 418 Seek Truth From Facts
In the next two days, Xu Zhengzhen followed Wan Haihong's instructions to go to work and go home directly after get off work. During this period, many people contacted him through connections and asked him to go out for dinner, but he refused.

Including Li Wanwan's cousin, including several bosses of Haichi Palace.

It also includes the lawyer Tan Zhongxin.

There were even some city bureau leaders and former colleagues, who he refused on the grounds that he was too busy investigating the case.

However, as the case of big star Zhao Jinmai made new progress, Xu Zheng and the second brigade also shifted their minds to this case.

At the regular meeting on Thursday morning, Wan Haihong, Yang Zhengchang, and Yan Zizhong all rushed to the judgment room. Xu Zheng was moved. It seemed that the investigation of this case was finally going to be decided. I heard that the capital companies and The capital behind the theater, in the past few days, all parties are entrusting relationships.

Because they all want to suppress this matter, or the police can investigate the case, but they cannot announce it.

They even wanted to get through the relationship and let the police in another place take over the case or the Ministry of Public Security would send someone directly. Unfortunately, it is said that a big boss in the Ministry was dissatisfied with these people meddling in the police affairs indiscriminately, and directly approved four words, "Seek truth from facts! "

Only then can the investigation continue.

And as the boss spoke, the inspection departments of the provincial government and the ministry issued inspection reports one after another.

Sure enough, the provincial department did not detect it, but only wrote the word suspected on the inspection report, and the inspection report of the Ministry directly showed that the deceased Su Guangquan was killed by a synthetic poison.

This neurotoxin, named 9-hydroxydopamine, appeared for the first time in China. I heard that it was sold on the black market abroad. It was synthesized from four non-lethal weak toxins.

It mainly acts on the nerves of the human body. For example, Su Guangquan gathered four kinds of toxins. They synthesized 9-hydroxydopamine neurotoxin in Su Guangquan's body. Within 30 minutes, this toxin would affect the brain and body to secrete dopamine, which the human body lacks. Dopamine can cause congestive heart failure, trigger shock syndrome, and finally death.

This is why Su Guangquan looked like a sudden death.

The truth is indeed the kind that Xu Zheng guessed before. This kind of poison can also be said to be a thousand-machine poison. It is a highly poisonous mixture of several weakly toxic things, and it cannot be detected by ordinary instruments.

It is said that the Ministry of Public Security did not detect the 9-hydroxydopamine neurotoxin at first, and later, it borrowed the equipment from the research base of the relevant department to get the results.

Of course, this alleged police is not going to admit its reliability.

However, the origin of this kind of gossip is often true, otherwise Team Wan and Chief Yang Zheng would come to the morning meeting of the Second Team today.

At the meeting, Wan Haihong held the two inspection reports that Li Wanwan had just printed out, "I just got a notification from my superiors that this case will be investigated according to the normal procedures, and the provincial department, the Ministry of Public Security, and the Ministry of Land and Resources will not intervene.

Nor did the police from other places join in.

Of course, if criminals from other places are involved later, that's another story. "

Yang Zhengchang also added: "During your handling of the case this time, someone may lure you with huge amounts of cash, women, or other seductive things, and someone may even take advantage of your shortcomings, or use your family as a threat to force you to serve it.

If you encounter this kind of thing, you must report it to the leader immediately. I think you all know the painful experience and lessons of our police in the past. Don’t be brave when things happen to you. Believe in your colleagues and trust your hat Badge."

Xu Zheng and the others glanced at each other, good guy, although Zheng Zhang used to be nagging, he mostly said things like exhortations, but he didn't expect to say such serious things this time. Could it be possible that this case could involve some big names and big capitals? ?

Wan Haihong frightened everyone when he saw Yang Zhengchang's words, and he did not comfort them, "Everyone can handle the case with a normal heart, and do whatever you want. Of course, if it involves those actors or even directors, this matter should be reported first. , we will arrange after discussion."

Well, after all, the leader asked you to handle the case normally, and at the same time asked you to ask for instructions when it comes to important people.

It is estimated that if this is the case, even Team Wan and Director Nie will have to ask their superiors for instructions.

After Wan Haihong and Yang Zhengchang encouraged everyone, they asked Li Wanwan to talk about the current situation of the second brigade of this case, thinking that it was Ji Meiyue who first made a simple case report. This time, she handed over the task to Li Wanwan. curved.

After all, Li Wanwan came from an extraordinary background, and he was not discouraged when he reported for the first time, "Through investigations through various channels in the past few days, we found out that on July 7th, the deceased Su Guangquan basically ate all the same diet as the superstar Zhao Jinmai. Same with her life assistant Fan Huihui.

If there are differences, it may be that different bottles are used for drinking water, and the same pair of chopsticks and spoons are not used for eating packaged food.

In addition, their rooms are different. If there is a problem with the water in the bathroom, and the various skin care products they use to wash their faces in the shower, it is difficult to check whether there is a problem with these.

However, the current survey department has taken samples of what I said and kept them in the Municipal Bureau, but they have not been sent to the capital for inspection.

As for the deceased Su Guangquan and Zhao Jinmai, apart from their work, they had no other relationship with lovers or bedmates. This was not only proved by Zhao Jinmai and Fan Huihui, but also by the rest of the crew.

Someone from their crew revealed in private that although Zhao Jinmai was unmarried, but there were important people following her, Su Guangquan didn't dare to have other thoughts at all.

However, we found a piece of women's underwear among his relics. According to analysis, in addition to Su Guangquan's DNA, this underwear also has the DNA of Zhao Jinmai and Fan Huihui. Therefore, it is not easy to determine the specific relationship between them. . "

Next, Li Wanwan briefly described the investigations in recent days, including Su Guangquan's interpersonal relationships, his nightlife, and his colleagues' evaluation of him.

Of course, these tasks are commissioned by local counterparts to do surveys.

It's just that the Second Brigade has summarized the information from these investigations, and has a few questions:
One is that the Second Brigade has yet to determine exactly how Su Guangquan was poisoned;
The second is whether Su Guangquan's poisoning has anything to do with Zhao Jinmai or Fan Huihui;
The third is whether the murderer is a member of the scene;
The fourth is whether the nerve poison is manufactured domestically or abroad, whether there is an antidote, and whether it will cause large-scale poisoning.

It can be said that the Second Brigade didn't know anything about the 9-hydroxydopamine neurotoxin. Xu Zheng felt that they should contact an expert in this field.

Of course, apart from these, there are still many questions that need to be investigated, but the most urgent task now is to first determine how Su Guangquan was poisoned. When the first team took over the case that day, they did not collect all the suspicious evidence at the scene.

Only the things in the hands of the deceased, all crew members and more than 100 people at the scene were collected, including various bottled water and various snacks, and even the perfume carried by the audience was detained by the police.

Even Director Zhang Guoshi's beloved thermos was detained by the police.

But at that time, it was in a movie theater, and Wanda Plaza was just outside the movie theater. There were four or five milk tea shops here. Su Guangquan had wandered around here, and there was no way to collect all the things he touched.

Now the things collected by the current survey team have been packed, and they will be sent to the Ministry of Public Security of the capital for inspection after the leadership orders.

Zhang Yuqi took the test report issued by the Ministry of Public Security and said: "This neurotoxin named 9-hydroxydopamine is composed of four other toxins. According to this test report, the other four are not fatal. People don’t feel anything after eating it, so can they detect what is carrying these four non-lethal toxins?”

Wan Haihong couldn't answer this question, "According to the explanation of relevant experts, this 9-hydroxydopamine neurotoxin is a toxin that recently appeared in the international black market. This is the first case of 9-hydroxydopamine neurotoxin poisoning in China. case.

As for the other four weak toxins, experts say it depends on luck. If the objects we provide carry these four toxins, the Ministry of Public Security can still detect them. "

It was detected that the four kinds of toxins were put into something by the murderer, whether it was the milkshake, the tea that Su Guangquan drank before, the breakfast he ate, or even the cigarette he smoked.
Once you have identified something, you can call up the monitoring in a targeted manner to find out who tampered with these four things, so that you can determine who the murderer is.

Otherwise, we can only use a stupid method to investigate everything. Unfortunately, Xu Zheng and the others have repeatedly watched the cameras, the statements of the waiters in the business, and the statements of more than 100 people in the screening hall, and they can't determine who is suspicious at all.
