Chapter 418 Seeking truth from facts

In the next two days, Xu Zhengzhen followed Wan Haihong's instructions when he should 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.

Including that lawyer Tan Zhongxin.

He even rejected some city bureau leaders and former colleagues on the grounds that they were too busy investigating cases.

However, as the case of big star Zhao Jinmai made new progress, Xu Zheng and the Second Brigade also turned their attention to this case.

During the regular meeting on Thursday morning, Wan Haihong, Yang Zhengchang and Yan Zizhong all came to the interrogation room. Xu Zheng was moved. It seemed that a decision was finally made on how to investigate this case. I heard that the capital companies related to Zhang Guoshi's movie and

In the past few days, all parties have been relying on relationships to capitalize on the capital behind the cinema.

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

They even wanted to work through connections and let the police from another place take over the case or the Ministry of Public Security directly sent people. Unfortunately, it is said that a big boss in the ministry was not satisfied with these people's random interference in police affairs and directly approved it with four words, "Seek truth from facts!"

"

Only then can the investigation of this case continue.

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

As expected, the provincial department did not detect it, but only wrote the word "suspected" on the inspection report. The inspection report from the ministry directly showed that the deceased Su Guangquan was killed by a synthetic poison.

This is named 9-hydroxydopamine neurotoxin. It is the first time it has appeared in China. I have heard that it is sold in the black market abroad. It is synthesized from four weak toxins that are not fatal.

It mainly acts on the nerves of the human body. For example, Su Guangquan gathered four toxins. They synthesized 9-hydroxydopamine neurotoxin in Su Guangquan's body. Within 30 minutes, this toxin will affect the brain and body to secrete dopamine, which the human body lacks.

Dopamine can cause congestive heart failure, shock syndrome, and eventually death.

This is why Su Guangquan looked like he died suddenly.

The truth is indeed what Xu Zheng guessed before. This kind of poison can also be said to be Qianji poison. It is a highly toxic substance formed by the confluence of several weakly toxic things, and it cannot be detected by ordinary instruments.

It is said that the Ministry of Public Security did not initially detect the 9-hydroxydopamine neurotoxin. Later, it borrowed instruments from the relevant department’s research base to obtain the results.

Of course, the police will not admit its reliability.

However, the origin of such gossip is often true, otherwise why would Team Wan and Zheng Chang Yang be attending the morning meeting of the Second Brigade today?

At the meeting, Wan Haihong took the two inspection reports that Li Wanwan had just printed and said, "I just got informed by my superiors that this case can be investigated according to normal procedures, and neither the provincial department, the Ministry of Public Security, nor the Ministry of Land and Resources will intervene.

No police from other places joined in.

Of course, if criminals from other places are later involved, let’s talk about it separately.”

Yang Zhengchang also added: "While you are handling the case this time, someone may use huge amounts of cash, women, or other tempting things to seduce you. Some may even use your shortcomings or use your family as a threat to force you."

serve it.

If you encounter this kind of thing, you should report it to the leader immediately. I think you all know from the painful experience of our police in the past. Don’t be brave when things fall on you. You must trust your colleagues and the person on your hat.

Police badge.”

Xu Zheng and the others looked at each other, good guys, in the past, although Chief Yang liked to nag, most of what he said was just instructions. Unexpectedly, he said such serious words this time. Could it be that this case could also involve some big shots and big capital?

?

When Wan Haihong saw that Yang Zhengchang's words frightened everyone, he did not comfort him, "Everyone can handle the case with a normal mind and do whatever they want. Of course, if this involves actors or even directors, this matter should be reported first

, we will make arrangements after discussion."

Yes, after all, the boss will let you handle the case normally, but at the same time ask you to ask for instructions when it comes to important people.

It is estimated that if this is really the case, even the Wan Detachment 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 team of the case. They thought that Ji Meiyue would make a simple case report first. This time, she handed over the task to Li Wanwan.

Bend.

After all, Li Wanwan had an extraordinary background, and he was not discouraged after reporting for the first time. “Through various channels of investigation in the past few days, we found that on July 12, the deceased Su Guangquan basically had the same diet as the big star Zhao Jinmai.

Same as her life assistant Fan Huihui.

If there are any differences, maybe they use different bottles for drinking water, and they don’t use the same pair of chopsticks and spoons to eat packaged food.

In addition, their rooms are different. If there is a problem with the water in the bathroom, the various skin care products they use when bathing, washing their face, or even using various skin care products, it is difficult to check whether there is any problem with these.

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

As for the deceased Su Guangquan and Zhao Jinmai, apart from working, they did not have an alternative relationship as 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 privately that although Zhao Jinmai was unmarried, big shots were paying attention to her, and Su Guangquan didn't dare to have other thoughts at all.

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

."

Li Wanwan then briefly described the investigation in recent days, including the interpersonal relationships around Su Guangquan, his nightlife, and the evaluation of him by his colleagues.

Of course, these tasks are all surveys commissioned by local colleagues.

The Second Brigade just summarized the information from these investigations and there are several questions:

First, the Second Brigade has not yet determined how Su Guangquan was poisoned;

The second question is whether Su Guangquan’s poisoning has anything to do with Zhao Jinmai or Fan Huihui;

The third is whether the murderer is one of the people at the scene;

The fourth question is whether this nerve poison is manufactured domestically or abroad, whether there is an antidote, and whether it will cause widespread poisoning.

It could be said that the Second Brigade did not know anything about 9-hydroxydopamine neurotoxin, and 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 top priority now is to 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, the entire crew, and more than a hundred people at the scene were collected, including various bottles of water and various snacks, and even the perfume carried by the audience were detained by the police.

Even Director Zhang Guoshi’s favorite thermos cup was detained by the police.

But we were in a movie theater at that time. After leaving the movie theater, we were in Wanda Plaza. There were four or five milk tea shops here. Su Guangquan had been here all the time and there was no way he could collect everything he had come into contact with.

The items collected by the on-site survey team have now been packed and will be sent to the Capital Ministry of Public Security for inspection upon orders from leaders.

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 contains these four non-lethal toxins?”

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

case.

As for the other four weak toxins, experts say it only 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 toxins were put into something by the murderer, whether it was the milkshake, the tea Su Guangquan drank before, the breakfast he ate, or even the cigarettes he smoked.

Once something is identified, you can call up surveillance to find out who has tampered with these four things. Only in this way can you determine who is the murderer.

Otherwise, we can only use stupid methods to investigate them all. Unfortunately, in the past few days, Xu Zheng and the others have repeatedly looked at the cameras and the confessions of the merchant waiters, as well as the confessions of more than a hundred people in the screening room, and they can't determine who is the suspicious person at all.
