The air-conditioning outlet of Screening Hall 2 is 5.2 meters vertically from the ground. Xu Zheng could only stand on the top of the ladder, holding a small flashlight in his mouth and working with both hands.
Not exciting at all.
After a while, my face was sweating.
However, he felt excited because there was indeed a dry mark inside the air outlet baffle.
Over time, some dirt will accumulate on the air outlet, and when it is blown by the cold air from the air conditioner, it will stick to it. The trace that Xu Zheng found now is light gray, which is very prominent compared with the surroundings.
"Brother Qiang, hand me the camera quickly. There are really traces on it as big as the bottom of a bottle, haha. Wei Yi's guess is correct." Xu Zheng said excitedly downwards.
"Haha, come down first, and I'll hand it to you." Zhuang Qiang raised the camera, and while Xu Zheng was coming down, he turned around and gave Wei Yi a thumbs-up with his right hand, "You are still a boring gourd cow, you don't usually do this. Speak up and it will be amazing!”
Wei Yi smiled sheepishly. 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 made the conjecture, if it hadn't been for everyone's discussion, I wouldn't have thought of it."
Zhang Yuqi was satisfied to see how united her subordinates were. Wei Yi and Ji Meiyue were both assigned from the first team. They usually don’t speak actively, but they must be concrete when speaking out. With the power of the collective, handling a case is never one person’s business.”
Although she said this, Zhang Yuqi sighed in her heart. Ordinary cases can definitely be solved step by step, but some tricky cases require people like Xu Zheng who can lead everyone out of the bottleneck of case handling.
Otherwise, why would he, Xu Zheng, be called the Little Detective? It is because of his active performance in every case that he is recognized by everyone.
Xu Zheng took the camera and took a few photos to keep as evidence before taking samples in the next step.
This kind of sampling is very simple. Dip a cotton swab in water, put the traces on the cotton swab, and then put the cotton swab into the evidence bag.
Of course, the only thing left is to clean the entire area, because this is a toxin after all. Although experts say that a single toxin is less toxic, since you see it, you must 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. "Captain Zhang, I suggest you tell the theater and let them clean this air outlet." "
Zhang Yuqi saw that Xu Zhengre was sweating profusely and his light blue short sleeves were wet with sweat. "Well, you come down and drink some water first. There is no need to install this iron plate now."
Not installing?
Xu Zheng understood what Zhang Yuqi meant as soon as he thought about it. Today, the entire second brigade came to the cinema and brought in a ladder. If this baffle is not installed now, as long as the murderer knows this, he will know that the police have discovered what he did. matter.
To be honest, if it were a suspect in other cases, the police would not alert the snake. But for the suspect in the Su Guangquan case, the police were not afraid that the suspect would run away. They would just 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 after traveling abroad, this is not the task of the Second Brigade. The Ministry of Public Security can directly issue a wanted warrant or activate extradition regulations.
On the way back, Zhang Yuqi called Wan Haihong and told Wan Haihong what she had just discovered. So far, this case finally had some clear clues. Even if the traces of the air conditioner outlet have not been tested, she is 80% certain that this is the murderer. traces left behind.
Who else but the murderer would put this thing at the air outlet of Hall 2? Besides, although the traces are a little dry, judging from the quality, they cannot be more than ten days old. According to the cinema's manager Chu, the air outlet is two years old. Not processed.
Wan Haihong praised the Second Brigade on the phone, and then asked Zhang Yuqi to send him photos of the evidence just collected, "I just got a call from the provincial department and asked us to cooperate with Huaxian Media Company to release a new case report. .
Bureau Nie temporarily ignored the case due to insufficient evidence.
Now that we have new clues, we can finally deal with the government and provincial departments. "
Wan Haihong did not mention Huaxian Media on the phone, which shows that he does not care about this large company with a market value of tens of billions. Maybe he, like all the members of the second team, cannot understand that these capitals want to slander Zhao Jinmai for the sake of 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 have been able to crawl to the air conditioner outlet if she had been poisoned, right?
As for saying that she is the mastermind, it is really impossible for her. The price of buying this 9-hydroxydopamine neurotoxin is 500,000 US dollars according to the international black market. In addition, hiring a killer must cost at least 500,000 yuan.
Including other miscellaneous money, even if she spends three million to kill her work assistant, is her brain going crazy?
This is just a motive. Now that there is evidence of the air conditioner outlet, it can be proved that she does not have the ability and time to take action directly.
Ji Meiyue smiled and patted Xu Zheng's car seat, "Xiao Zheng, now that we have evidence, the suspicion of the big star has been reduced by one point. Do you want to take some time to visit?"
"Sister Meiyue, this joke is not funny at all." Xu Zheng asked Zhang Yuqi while driving: "Team Zhang, is there any news from the Detective Qi detachment?"
"Not yet. I guess it's because the conjecture you proposed is difficult to discover, right?" Zhang Yuqi flipped through her phone, thought for a while, and called Qi Haibing, "Hey, Detachment Qi, have you discovered it?"
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 100 times, and the video image was enlarged. It seemed like something had been shot into the device. There were milkshakes in plastic cups.
It's just that although the current high-definition cameras can achieve 256 million frames per second, if the slow playback is based on 25 frames, it will be 1024 times. That is, the original 1 second image took 1024 seconds to play back, which means that the slowest playback can be a thousand times. .
But obviously the equipment of the provincial department is not powerful enough. On the computer screen, when slowed down a hundred times and the resolution enlarged, the video picture is a bit blurry. Moreover, the thing is very fast and small, making it difficult to determine at all.
Therefore, Qi Haibing didn't dare to be sure, so he had to reply to Zhang Yuqi: "Team Zhang, when you return to the city bureau, you can come over in person. The video picture is a bit blurry and not easy to handle. I'm not sure if there is any Something."
Zhang Yuqi hung up the phone and told Xu Zheng what Qi Haibing said, "It seems that the murderer's poisoning method must have used high technology."
In recent years, with the development of 6G networks, there have been more and more cases of various high-tech remote control cases. Some capable people have truly achieved the goal of killing people thousands of miles away by modifying drones to kill target people remotely.
And this kind of high technology is very difficult to check. For example, the sales volume of this drone in China every year reaches one million units, and most of them except teenage enthusiasts are used to spray pesticides on crops.
This kind of drone sold does not have a license plate like a car. It is small, fast, and more concealed. If you use a drone to launch a tiny poison at a target in the dark, and then evacuate directly, this will This modus operandi completely avoids the Sky Eye system spread throughout the city.
Although Xu Zheng is a young man, he has not done much research on these high technologies, such as drones. He only learned how to operate them when he was at the police station. There are also some micro electric shock devices used by criminals, like small flashlights. , but it can stun people instantly.
What impressed him most was the online murder case in Nanhai Province. The murderer was able to kill the victim while chatting online. The method was that the murderer played a depressing and sad video while chatting online. Music, and the murderer shared many very negative videos, articles, etc. with the victim. Over time, the victim did not die of suicide, but died of heart failure.
As for the suicide websites mentioned on the Internet, Xu Zheng has never heard of such a case in China for so many years as a police officer.
Everyone returned to the detachment. Zhang Yuqi took Xu Zheng and Lang Shaobai to the picture investigation detachment. The remaining team members checked the video of the Wanda Cinema in Yiqiao District. The surveillance video of 15 years ago from the day of the incident was checked. All the people with Anyone who carries a backpack or sneaks into Hall 2 must be carefully screened.
On the way back just now, Lang Shaobai and others analyzed the method used by the murderer to put the venom into the air-conditioning vent. After discussing for a long time, they could not think of a method because they all believed that the murderer could not have used a ladder, which was too conspicuous.
Even if the cinema closes at three in the morning, if the murderer enters Hall 2 with a ladder at this time, can the camera not capture it?
Xu Zhenglu also wondered what method the murderer used, but he was also at a loss. There was no need for a ladder. Could it be that the murderer was Spider-Man?
When they arrived at the picture reconnaissance detachment, everyone was polite. Qi Haibing pointed to the paused computer screen and said: "Commander Zhang, look, this is the result of a video magnified 50 times. The picture is a bit blurry, but it can be seen that something has definitely penetrated into the milkshake cup. above."
Zhang Yuqi only needed to make sure there was something. As for what it looked like, she didn't really care. She was more concerned about how the murderer operated it.
Regarding this issue, Qi Haibing and several of his scouts became interested. They pointed to a picture of Su Guangquan eating ice cream and standing in front of the guardrail and analyzed: "We just demonstrated it. Based on the ballistic analysis of the thing on the screen, , it should have come from a woman on the left side of Su Guangquan’s body, three meters away from him.”
As a picture scout operated the computer, a fashionably dressed girl soon appeared on the screen. Why do I say girl? Because this girl had a ponytail, a black mask, and a pink backpack behind her back.
Wearing a light blue princess dress, she looks like a young girl.
Moreover, in the picture, the girl is playing with her mobile phone three meters away. It is not clear what model the mobile phone is, but the mobile phone case should be rabbit-shaped and pink.
