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

Chapter 426 Two Clues
The vertical distance from the air outlet of the No. 2 projection hall to the ground was 5.2 meters. Xu Zheng could only stand on the top of the ladder, holding a small flashlight in his mouth and working with both hands.

It's not good at all.

After a while, his face was sweating.

But he was excited because there was indeed a dry mark inside the air outlet baffle.

After a long period of time, some soil will be deposited on the air outlet, and when it is blown by the cold air from the air conditioner, it will stick to it. Now the trace that Xu Zheng found is light gray, which is very prominent compared with the surroundings.

"Brother Qiang, hand me the camera quickly. There are really marks the size of the bottom of the bottle on it, haha. Wei Yi's guess is right." Xu Zheng said excitedly towards the bottom.

"Ha, come down first, and I'll pass it to you." Zhuang Qiang raised the camera, and while Xu Zheng was down, he turned his head and gave Wei Yi a thumbs-up with his right hand, "It's still you, a boring gourd cow, who doesn't usually Make a sound, it's amazing to make a sound!"

Wei Yi smiled embarrassedly. After all, he was not as thick-skinned as Zhuang Qiang and Peng Yue. "It's all thanks to everyone's discussion. If Xu Zheng hadn't put forward a conjecture, if it hadn't been for everyone's discussion, I would never have thought of it."

Zhang Yuqi looked at the unity of her subordinates with satisfaction. Wei Yi and Ji Meiyue were assigned from the first team. It is true that they are not active in speaking, but as long as they speak out, there must be a real hammer. The power of the collective, handling a case has never been a matter of one person.”

Even though she said so, Zhang Yuqi sighed in her heart. Ordinary cases can definitely be solved step by step, but some tricky cases need someone like Xu Zheng who can lead everyone out of the bottleneck of handling the case.

Otherwise, why would Xu Zheng be called the little detective? It was because of his active performance in every case that everyone recognized him.

Xu Zheng took over the camera and took a few photos as evidence before sampling.

This kind of sampling is very simple. Take a cotton swab and dip it in water, put something on the trace on the cotton swab, and then put the cotton swab into the evidence bag.

Of course, the rest is to clean the entire area, because it is toxin after all. Although experts say that a single toxin is less toxic, since you have seen it, you have to clean it up no matter what.

After working for a long time, Xu Zheng was still dissatisfied. Although the air outlet on the left front is not big, there is a lot of dust stuck inside, "Team Zhang, I suggest telling the theater that this air outlet should be cleaned up. "

Zhang Yuqi saw that Xu Zhengre was sweating profusely, and his light blue short sleeves were also wet with sweat, "Well, you go down to drink some water first, this iron plate doesn't need to be installed yet."

Do not install?
After thinking about it, Xu Zheng understood Zhang Yuqi's meaning. Today, the Second Brigade dispatched to the movie theater and brought a ladder. Now the baffle is not installed. As long as the murderer knows this, he will know that the police have discovered what he did. matter.

To be honest, if it was a suspect in another case, the police would not startle the snake, but for the suspect in the Su Guangquan case, the police would not be afraid that the suspect would run away, and they would run away as long as the second brigade solved the case and identified the suspect. .

As for whether the suspect can be brought to justice when he goes abroad, this is not the task of the Second Brigade. The Ministry of Public Security can just issue a wanted warrant or activate the extradition regulations.
On the way back, Zhang Yuqi called Wan Haihong to tell Wan Haihong what she had just discovered. So far, she finally had some clear clues in this case. Even though the traces on the air outlet of the air conditioner have not been tested, she is [-]% sure that this is the murderer. left traces.

Besides the murderer, who else would put this thing on the air outlet of the second hall? Besides, although the trace is a bit dry, it will not last more than ten days, and according to the director Chu of the theater, the air outlet has been there for two years. Not dealt with.

Wan Haihong praised the second brigade on the phone, and then asked Zhang Yuqi to send him the photos of the evidence collected just now, "Just now the provincial department called, let's cooperate with Huaxian Media Company to release a new case report .

Ju Nie temporarily evaded the case on the grounds of insufficient evidence.

Now that we have new clues, we can finally deal with the government and the provincial government. "

Wan Haihong didn't mention Huaxian Media on the phone, which shows that he doesn't care about this big company with a market value of tens of billions. Maybe he, like all the members of the Second Brigade, can't understand how these capitals want to slander Zhao Jinmai for the movie box office. reputation.

Now that we have this clue, it can be proved that the possibility of Zhao Jinmai being the murderer is very small, otherwise she would not be able to crawl to the air conditioner outlet after being poisoned, right?

As for saying that she is the mastermind, it is really impossible for her to buy this 9-hydroxydopamine neurotoxin according to the international black market price of 50 U.S. dollars, plus the minimum cost of hiring a killer is 50 RMB.

Plus other miscellaneous money, even if she spends 300 million to kill her work assistant, is she out of her mind?

This is just a motive. Now that there is evidence of the air-conditioning outlet, it can completely prove that she does not have the ability and time to do it directly.

Ji Meiyue patted Xu Zheng's car seat with a smile, "Xiao Zheng, now that we have evidence, the suspicion of that big star has been reduced by one point. Do you want to take some time to visit?"

"Sister Meiyue, this joke isn't funny at all." Xu Zheng asked Zhang Yuqi while driving, "Team Zhang, is there any news from Tuqi Qi Detachment?"

"Not yet, maybe the conjecture you raised is hard to find?" Zhang Yuqi flipped through her phone, thought about it, and then called Qi Haibing, "Hey, Qi Detachment, have you found anything?"

Qi Haibing on the other end of the phone scratched his head. He didn't know how to answer Zhang Yuqi's question, because the computer screen in front of him had been slowed down by 100 times, and the video image was zoomed in. It seemed that something had shot into the device. There are milkshakes in plastic cups.

It’s just that although the current high-definition camera can achieve 25600 million frames per second, if it is slowed down according to 25 frames, it will be 1024 times, that is, the original 1-second image takes 1024 seconds to play, which means that the slowest can be slowed down by a thousand times .

But obviously the equipment of the provincial department is still not powerful enough. On the computer screen, slow playback a hundred times and enlarge the resolution, the video picture is a bit blurred, and the speed of the thing is very fast and the size is small, it is difficult to determine at all.

Therefore, Qi Haibing didn't dare to be sure, so he had to reply to Zhang Yuqi: "Team Zhang, so, when you return to the Municipal Bureau, you come over in person, the video is a bit blurry, it's not easy to deal with, and I'm not sure if there is something wrong with it." something."

Zhang Yuqi hung up the phone and told Xu Zheng what Qi Haibing had said, "It seems that the murderer's method of poisoning should be high-tech."

In recent years, with the development of 6G networks, there have been more and more cases of various high-tech remote control. Some capable people shoot and kill targets remotely by modifying drones, and they have truly managed to take the head of a person thousands of miles away.

Moreover, this kind of high-tech is very difficult to find out. For example, the annual sales of drones in China have reached 100 million units, and most of them are used to spray pesticides on crops except for young amateurs.

This kind of drone sold out is not like a car with a license plate. It is small, fast, and more concealed. If a drone is used to launch a tiny poison at the target in the dark and then evacuate directly, this This modus operandi completely evades the SkyEye system that pervades the city.

Although Xu Zheng is a young man, he doesn't have much research on these high technologies, such as drones, which he only learned to operate when he was in the police station, and some tiny electric shock devices used by criminals, like a small flashlight , but it can stun people all at once.

What impressed him the most was that there was an online murder case in Nanhai Province. The murderer was able to kill the victim during the online chat. Music, and the murderer shared a lot of videos and articles with very negative energy to the victim. Over time, the victim did not commit suicide and died of heart failure.

As for the kind of suicide website mentioned on the Internet, Xu Zheng has been a policeman for so many years, and he has never heard of such a case in China.

When everyone returned to the detachment, Zhang Yuqi took Xu Zheng and Lang Shaobai to the picture investigation detachment. The remaining team members checked the videos of the Wanda Cinema in Yiqiao District. Anyone with a backpack or sneaking into Hall Two must be screened carefully.

On the way back just now, Lang Shaobai and the others analyzed how the murderer used the method to put the venom into the air-conditioning outlet. After discussing for a long time, they didn't think of a way, because they all thought that the murderer couldn't use a ladder because the ladder was too conspicuous.

Even if the movie theater closes at three o'clock in the morning, but at this time, the murderer carried a ladder and entered Hall No. [-]. Could the camera not be able to capture it?

Xu Zhenglu also thought about what method the murderer used, but he was also at a loss. There is no need for a ladder. Could it be that the murderer is Spider-Man?

When we arrived at the Tusun Detachment, everyone was polite, and Qi Haibing pointed to the paused screen of the computer and said: "Look at Team Zhang, this is the result of zooming in on the video 50 times, the picture is a bit blurry, but it can be seen that something has stuck into the milkshake cup above."

Zhang Yuqi only needs to make sure there is something, as for what it looks like, she doesn't care much, what she cares more about is how the murderer operates it.

Regarding this question, Qi Haibing and several scouts under him became interested, pointed to a picture of Su Guangquan standing in front of the guardrail eating ice cream and analyzed: "We demonstrated it just now, according to the ballistic analysis of the thing on the screen , it should come from Su Guangquan's left body, a woman three meters away from him."

As a scout operated the computer, a stylishly dressed girl soon appeared on the screen. Why did she say girl, because the girl had a ponytail, a black mask, and a pink backpack behind her back.

Wearing a light blue princess dress, no matter how you look at it, she looks like a young girl.

Moreover, in the picture, the girl is playing with her mobile phone three meters away. The model of the mobile phone is unclear, but the mobile phone case should be in the shape of a rabbit and pink.
