Xu Zheng and Zhang Yuqi strongly agreed with Wei Yi's conjecture of placing a fourth poison in the ventilation ducts.
Peng Yue couldn't wait to urge everyone, "Then why should we hold a meeting? Let's go directly to the eucalyptus discovery site and determine the type of poison first."
Zhuang Qiang also stood up and waved his hand, "That's it, once we are sure it is the air outlet of the central air conditioner, we can start from here. Maybe we can find the murderer by checking the surveillance a few days before the incident."
】
Xu Zheng and Lang Shaobai also had this idea. Maybe it was like Zhuang Qiang said, and there would be clues once they checked.
But Zhang Yuqi pressed her hands down, but did not give a direct order, "You guys stay here, don't go anywhere, and don't plan to make a call. I'll go out."
After she finished speaking, she left here without looking back, leaving everyone looking at each other in confusion. Xu Zheng was moved in his heart and said jokingly: "Brother Lang, have many people invited you to dinner in the past two days?"
"Well, don't tell me, there are all kinds of people looking for me. Even one of my former university teachers called me. Wow... there's a lot of energy behind it." Lang Shaobai took out his mobile phone and put it on the table. Above, its intention is self-evident.
Then Xu Zheng smiled and put his phone on the table.
Anyone who can join the criminal police detachment is not a fool. Now the second brigade is responsible for Su Guangquan's case. Some people hope that the police will solve the case as soon as possible, while others hope that the police will postpone the case. Of course, some people do not want the police to solve the case.
When Zhuang Qiang took out his mobile phone, he also sighed, "Yesterday, my old colleague suddenly invited me to dinner. At this time, none of us policemen know what the busiest thing is in the second brigade right now."
Ji Meiyue gave a bitter smile, "It is estimated that no one in our second brigade, only Captain Zhang, would dare to ask her to go through the back door. What about you, Wanwan, is there someone asking you to find out about Su Guangquan?"
"No, I go home after get off work now. I basically don't have any extra energy for socializing. I don't want to move when I get home." As the Second Brigade began to investigate Su Guangquan's case, Li Wanwan's work increased exponentially. If it weren't for Ji Meiyue helped her share some of the workload, and her overtime work had to be extended by one hour.
Wei Yi covered the phone on the table and fumbled with the back of the phone with his hand, "There are so many of us frontline investigators, so there are probably more people looking for leaders. Whether this operation is fast or slow depends on what it means. .”
Xu Zheng tapped the table with his finger, "It doesn't make any difference to us whether the progress of the eucalyptus is slow or slow. The worst we can do is collect the clues and find the murderer without arresting him. We can just catch fish."
There are only seven people in the second brigade including the captain. Li Wanwan is not yet a formal investigator. Unlike the first brigade, they are also divided into two squadrons, but there are five or six people in one squadron.
Therefore, the second team can only try its best to complete one piece, and it will be too busy for any more.
I think at the beginning, the focus of the establishment of the second brigade of the Municipal Bureau was to focus on old and old eucalyptus. However, after half a year of establishment, it only completed two old eucalyptus. But overall, the total number of eucalyptus completed by the second brigade was no less than that of the first team. How many.
Basically, a eucalyptus will not last more than a month.
This also led to the fact that the Second Brigade did not even have time to fish during work. They were either looking for clues or on the way to catch suspects.
Ten minutes later, Zhang Yuqi appeared at the door of the trial room, waved her hand, "Let's go, set off immediately, remember the confidentiality principle."
It was only when everyone got downstairs that they realized that Zhang Yuqi did not bring anyone with her for spot inspection or trace inspection when she went to the discovery site this time, but she borrowed tools from the Technical Investigation Brigade, which meant that the Second Brigade had to personally carry out the investigation at today's discovery site. Started to investigate.
Fortunately, Xu Zheng is a professional field survey technician.
Seven people and two cars went straight to Wanda Plaza in Hitotsubashi District, while Li Wanwan stayed at home to sort out information.
On the way, Zhang Yuqi did not notify the Liulihe Police Station, but she said to Xu Zheng: "Call your master Anru and ask her to go to Wanda Plaza alone first, and then meet up there."
"Team Zhang, there's no need to keep it so strictly confidential. It's been six days since the incident occurred. Even if the murderer couldn't destroy the scene of the incident, it's hard to say whether there are any traces after these days." Ji Meiyue used her mobile phone to connect to the Second Brigade. The surveillance cameras installed at the discovery site unfortunately never found anyone sneaking in.
There are only two reasons why no one sneaked in. One is that the murderer did not leave any obvious traces when he committed the crime, and the other is that Wei Yi's guess was wrong.
Zhang Yuqi sighed, "This eucalyptus seems simple, but the fact that the murderer could buy 9-hydroxydopamine neurotoxin abroad has attracted the attention of the ministry. Unfortunately, there has not yet been an investigation abroad to find out who bought it. This toxin.
The immigration administration department found no trace of toxins flowing in.
Now some of the leaders above are worried that the murderer will commit suicide again and ask us to solve the problem as soon as possible. "
"If traces of murder are found at the crime scene later, we can follow this line to investigate. By the way, Captain Zhang, Xiao Zheng previously assumed that the murderer used the technique of flying needles through the air to kill milkshakes and acid. Have you reported the suggestion of injecting toxin into plum juice to Team Wan?" Ji Meiyue asked curiously.
Zhang Yuqi opened her phone and took a look. There was no new message from Team Wan on it. She shook her head, "I must have told him about this. It's just that the plastic cups containing milkshakes and plum juice are currently in the laboratory of the Ministry of Public Security.
In that place, even if our director calls them personally, the news will not be returned quickly. "
Xu Zheng smiled and said, "This is not a problem. Let's assume that there are tiny pinholes on the two cups or that the murderer used very small things to inject the venom. Then let the detective team do some research. Su Guangquan bought milkshakes and acid. Video of plum juice along the way.”
Because what Xu Zheng guessed was an extremely small thing that could not be seen with the naked eye, even if he watched this video on the computer, he could not find it. He could only use special equipment to process the video slowly. While playing it, you have to enlarge the picture 50-100 times, so that you can see clearly whether there is anything like what Xu Zheng guessed.
"That's right." Zhang Yuqi also responded, "You assume it first and then let the picture detective do the operation. I think it will definitely work. When I reported it to the Wan detachment and the director, I actually forgot about it."
Zhang Yuqi shook her head with a wry smile. As for why she hadn't thought of this, she was mainly worried that the leaders above her would not agree to continue to investigate the case.
She did not tell Xu Zheng and others that the attitude of the leaders at higher levels towards this case was unclear, mainly from the government side. She hoped that the Changming police could cooperate with the film's distribution company, Xuanfa Company, in promoting it. In this case, the film would be If the popularity of the film continues unabated, the box office will continue to rise. For these people, the advantages far outweigh the disadvantages.
Besides, the outside world does not understand the speed of police investigation. In the past, people believed that catching the murderer did not mean that the case had been solved. The criminal case would not be over until the court confirmed the murderer's crime.
Therefore, a eucalyptus lasts for six months, not a year.
Six months!
After six months, no one will pay attention to this eucalyptus.
Even if there are, there won't be too many people.
Therefore, the film promotion company came up with a new idea, which was to first announce that the movie had turned into a murder movie, triggering new interest in this news point.
Besides, it's only been six days since Su Guangquan's murder, so it's understandable that the police can't find the real culprit.
Therefore, if according to the government's statement, the Second Brigade should be slower in investigating the case, and it is best to have results after three days, and during these three days, Zhang Guoshi's film promotion company will claim to the public that Su Guangquan did not die suddenly. But he was killed.
As for the murderer, the police have not identified it yet. It is suspected that there may be something wrong with the Peach Shake that Su Guangquan drank last time.
The propaganda department of Changming City and even Pingjiang Province approved the film promotion company's article. The attitude of the provincial department was a bit immodest, but on the Changming Municipal Bureau, Director Li Nie and Team Wan were opposed.
The main reason is that there is something wrong with the last sentence of this announcement. According to this article, Mixue Bingcheng and big star Zhao Jinmai are directly placed at the forefront.
There is also the fact that the first team of the city bureau’s heavy duty team that originally investigated this case was not capable enough.
Of course the Municipal Council does not agree with this article.
In three days, this news will become an established fact in the minds of netizens. Even if the Changming City police announce the true situation of Eucalyptus three days later, the losses caused to Mixue Bingcheng and Zhao Jinmai will be irreparable. of.
Zhang Yuqi is now the captain of the Second Heavy Duty Brigade of the Changming Municipal Bureau. For the sake of her own honor, she does not want the film promotion company to release such news. Doesn't this show the incompetence of the police?
Ordinary people don't understand the process of handling the case. Most netizens agree, but there are also many who know the truth. If the government's wishes are truly followed, the Changming police will have a handling agency that takes care of the capital.
Therefore, the two directors Li and Nie were firmly opposed.
But after all, the Municipal Public Security Bureau is under the dual leadership of the government and the provincial department. Therefore, the investigation of this case does not depend on whether the murderer can be found immediately, but on the game between all parties.
As for Zhao Jinmai and Fan Huihui, they took the initiative to give Xu Zheng benefits in the morning, which showed that they were very eager to cooperate with the Changming City Police. As women, why not use their greatest advantage.
If Xu Zheng could take the initiative to reveal something in the morning, or negotiate, or coerce, or cooperate with each other for mutual benefit, maybe Zhao Jinmai might treat him to dinner.
Of course, Zhang Yuqi knew the ins and outs of these things and could see the motives of Zhao Jinmai and Fan Huihui, but Xu Zheng at that time did not understand the true meaning of the beauty because of poor information, which was really funny.
Ji Meiyue looked at her team leader, who was also her best friend in private, and was stunned as she was talking. But now, she started laughing inexplicably.
She secretly stretched out her right hand and pinched Zhang Yuqi, "Captain Zhang, why don't you call the Wan detachment and ask him to tell the detective detachment?"
Zhang Yuqi came to her senses and looked at Xu Zheng, who was driving in front, and Ji Meiyue, who was next to him. They were low-level investigators who knew how to immerse themselves in the investigation and did not care about the difficulties of their leaders.
If there are no clues, forget it. Now that there are clues, will Nie Bureau and Wan Detachment support it or not?
Fortunately, the leaders of the municipal bureau are relatively strong. With the instructions of the boss at the Ministry of Public Security to "seek truth from facts," they can investigate the case as they please.
"I thought about it, and after a while I personally called Qi Haibing, the deputy detachment on the map detective side, and asked him to help find a few new colleagues to help us investigate." Zhang Yuqi finally decided to contact the map detective herself. .
You can’t blame everything on your leaders.
Now she also wants to understand that as long as she detects the case by herself, it will be useless for the leaders at one level above to play "drag tricks".
Xu Zheng glanced at Zhang Yuqi through the rearview mirror in confusion, "Can you do this?"
"Huh...what do you mean, how can the Wan detachment still find fault with me?" Zhang Yuqi rolled her eyes at him, "I'm not going to kill it first, but I'm going to try another idea. After all, we need to make our own guesses." Find a way to prove it.”
Ji Meiyue also nodded in support, "If we break the eucalyptus in two days and identify the murderer, then how do you think Zhao Jinmai will thank us? What about you, Xu Zheng?"
"You shouldn't ask me, you should ask Brother Qiang and Peng Yue. You two must hope that Zhao Jinmai will marry you, otherwise you can use the walkie-talkie to ask them." Xu Zheng is not ignorant of style. This morning Zhao Jinmai If he were Zhuang Qiang, he would definitely think too much about the abnormality of Jin Mai and Fan Huihui.
It's a pity that Xu Zheng has no idea about them at all.
While talking, everyone rushed to the parking lot of Wanda Plaza. As soon as they got off the car, the high temperature around three o'clock in the afternoon made people feel like they were in a boiling water pot. I don't know why, but the summer in Changming City is always hot and long.
Everyone got off the car without delaying for a second and walked quickly into the mall. It was still cooler here. Xu Zheng looked around the first floor of Wanda. Maybe because of the summer vacation, there were a lot of people, and most of them were girls.
One is dressed cooler than the other, with short sleeves and hot pants, and a pair of long legs wearing small slippers. They are very dazzling.
It's a pity that as police officers, Xu Zheng and the others really didn't dare to stare at these female college students in this scene with cameras everywhere.
Rushing to the Wanda Cinema on the second floor, Anru was sitting alone in a corner of the waiting hall. She was fat and old. She was sitting with these boys and girls and was particularly conspicuous. When she saw Xu Zheng and the others arrived, she Breathed a sigh of relief.
"Master, why are you sitting here, like a mother catching her child in early love." Xu Zheng walked up to Anru and teased her. Although Anru was vigorous and resolute at work, she was a complete cat mother to her daughter and son. .
Feng Tingting and her brother are not afraid of Anru at all. No, she is 17 years old this year, and Anru has begun to worry about her premature love. She wants to watch a movie without anyone to accompany her. In the past, Xu Zheng could take her with him when he had a rest. Came here to watch a movie.
But now Xu Zheng doesn't have time on his own.
Anru and Zhang Yuqi said hello, and then smiled and scolded Xu Zheng: "You stinky boy, I told Tingting the day before yesterday that her grandma Xu misses her. No, she has been shouting at me to send her off every day for the past two days. Go to your house, I see, she just wants to go out and play."
"Haha, if Master doesn't do this, if Tingting wants to go, I'll ask Sister Xiaoxin to pick her up, or she can take a taxi herself. She's already so old, and you still want her to attend cram school during the summer vacation."
While Xu Zheng and An Ru were talking, everyone walked to the No. 2 screening room. As the door lock opened, Manager Chu from Wanda Cinema who followed them was about to turn on the central air conditioner.
Zhuang Qiang quickly grabbed him and said, "Manager Chu, let's not turn on the air conditioner today. We want to do a test inside. By the way, can you help us find a telescopic ladder for us to use?"
Manager Chu looked at Zhuang Qiang a little doubtfully. If the air conditioner is not turned on on such a hot day, even if Hall 2 is cooler, it will make people sweat after a while.
Anru came over and whispered a few words to him. Manager Chu nodded, turned around and walked out without asking any more questions. After a while, he came over personally carrying a telescopic ladder, put it down, and asked someone to take it away. I left after a bag of mineral water from Nongfu Spring.
"Team Zhang, if there are no other arrangements, should I wait for you outside the door, or should I go back first?" Anru saw that the Second Brigade was about to check the ceiling of Hall No. 2, and realized that they might have found some clues, so she asked Say goodbye.
Zhang Yuqi thought for a while, this case is still not easy to involve too much, but there are still some things that need Anru's help here, "Director An, can you wait for us outside for a while and do us a favor by the way? If anyone wants to join in, Come here, no matter what he did.
You just need to keep an eye on it for us. "
This time all the members of the Second Brigade rushed here. Maybe by this time, those who are paying attention to this case have already got the news, and even the murderer may know it.
At this time, no one can say whether he will come to Wanda Cinema.
Of course Anru didn't know this. She came here today to cooperate with Zhang Yuqi's actions. She walked out of Hall 2, helped close the door, thought about it, and sat back down where she was.
After Anru left, Zhuang Qiang and the others quickly stretched out the ladder, and then Xu Zheng took the equipment for the current survey and waited for the ladder to climb to the air outlet of the air conditioner.
Because this hall is nearly 1,000 square meters, has a total of 161 seats, and has four air outlets. Among them, the air outlet in the front left is facing where Su Guangquan was sitting at the time, the second seat in the front row from the left.
So this is where the murderer most likely placed the toxin.
Sure enough, when Xu Zheng climbed up, the screws of the air outlet did look like they had just been loosened. Because this is the ceiling, there will always be a little dust on it over time, but these four screws clearly showed signs of being rubbed. .
Xu Zheng was wearing gloves, a mask, a hood, and a tool bag on his body. He quickly removed the four screws and handed the plastic plate over. "There may be fingerprints on this thing. You guys can pick it up." Wear gloves all the time.”
"Xu Zheng, do you mean that someone has touched this air outlet?" Peng Yue immediately asked excitedly.
"Well, it looks like it to me. Wait a moment, and I'll take a closer look inside. I haven't found any traces of toxins yet." Xu Zheng raised his neck and felt a little uncomfortable. It was dark inside the air-conditioning vents. He could only use tools to I found a flashlight in my bag.
