At the morning meeting the next day, Zhang Yuqi brought bad news to everyone. Except for that fingerprint, no other fingerprints were found yesterday, and DNA could not be extracted. The hair found by Captain Yang had been tested for DNA, but It was not matched with anyone related to this project, nor did it belong to the hostess.
As for whose hair it belongs to, I guess I have to ask Mr. Xie first. However, since it has nothing to do with this article, Zhang Yuqi did not talk about it.
"Now that Wu Mei is missing, Du Longtao, Xue Jiaping, and Bai Shuting can be officially listed as suspects. It is difficult to say whether there are other suspects. However, the actual evidence currently available is only the blood of the missing person Ping Mengmeng. Fingerprints, the evidence chain is relatively thin, so I think we need to follow this clue to investigate further.
Ping Mengmeng was injured on the first floor of the sinking, and there were blood marks in the bedroom. This shows that Du Longtao was indeed seriously injured that day, because anti-noise devices were used in the bedrooms on the fifth floor of the sinking. I have already inquired, and Du Longtao’s neighbors basically I have never seen him or heard any special noises from his house.
In this case, I suggest that we, on the one hand, investigate the doctors and nurses who performed the surgery on Du Longtao.
On the other hand, we will re-investigate Ping Mengmeng’s life circle. This time, we will focus on asking passers-by, Ping Mengmeng’s family, relatives, neighbors, friends, etc. who were interviewed to see if they have seen Du Longtao or these three people. The scene of three people getting along with each other peacefully and cutely.
Please add, what else needs to be investigated today? "
Lang Shaobai frowned, "I have seen the previous investigation of Ping Mengmeng's life circle by the special team. If we check it again, we will have to apply for police force from the Wan Detachment again.
Will such a big news be known to the suspect? "
The story about the disappearance of Wumei is relatively influential in Changming, mainly because it was widely spread on the Internet at that time. It took two or three years for this story to be constantly mentioned on the Internet by interested people, and the special team at that time was covered up. He has nicknames with ironic meanings such as "Idiot Detective" and "Not as good as the Sweet Potato Team".
Now that the investigation has reached this level, a total of more than 200 police officers have been dispatched, and four to five hundred people have visited and investigated. If the investigation was to investigate Wumei's living circle, even more police officers would be deployed.
Lang Shaobai was worried that such a big news would be known to Du Longtao and even to Xue Jiaping. If he knew, Xu Zheng's plan would be difficult to carry out.
Although the targets of the investigation will sign confidentiality agreements, some people may take risks for money.
Zhang Yuqi obviously thought about this problem, "This is inevitable. As long as we restart this case, people like Bai Shuting or her husband Yan Hongqiang will know sooner or later that we are investigating Du Longtao.
However, yesterday I discussed with several leaders of the Wan detachment that it is not important whether Xue Jiaping returns to the country or not. Even if he is absent from the court, the Ministry of Public Security can initiate his extradition as long as the verdict is issued.
Therefore, we follow our own pace. The demolition plan has been approved by the Wan Detachment. At this time, the Ministry of Public Security is also preparing an arrest warrant for Xue Jiayun, an online fugitive. Although it has no real legal effect, it is enough to block his return to the country. "
Xu Zheng felt that this was the way to go. The Second Brigade couldn't ignore clues for the sake of confidentiality. "I think if we find the doctor and nurse back then, we might be able to get some clues from them. There's also the question that Wanwan raised yesterday." At that time, the department directors of major hospitals were investigated. I think this suggestion is very good. However, there are 400 to 50 second-level and above hospitals in Changming. It is estimated that there must be 400 to 500 doctors who can perform surgical operations. This also requires a lot. Police force.”
Zhuang Qiang slapped the table, "Since you don't have to worry about the suspects knowing that we are investigating them, and the leaders also pay attention to it, captain, you can feel free and bold to make requests to the Wan Detachment. It would be best to have more police force, so that we don't have to go out in person." Field service.”
It's not that the Interpol Office can't do field investigations, it's that the workload is too heavy. There are more than 200 people in Ping Mengmeng's circle of people to investigate. This would take just a few people from the Second Brigade, at the fastest, a week.
Therefore, at this time, it is much easier to ask the leader to borrow colleagues from other fraternal units to conduct investigation.
Zhang Yuqi feels that there is no need for too much police force, “Surgeons are not general practitioners, and many doctors are proficient in one category.
Think about it again, what kind of doctor would perform surgery on members of a community organization?
Generally, far-sighted societies will invest in surgeons when they are still students. However, it takes at least ten years for such surgeons to perform secondary surgeries, which is too long.
Therefore, most societies are looking for people who are in urgent need of money or who have bad personal ethics, such as losing money playing cards or borrowing money they shouldn't.
We only need to focus on investigating which hospital's surgeons often take leave before February 2025 but their medical skills are constantly improving. Because there are many community members, there must be a lot of surgical operations, and the changes in the medical skills of the doctors under their command must not be hidden from the department director. "
No one knows how many social organizations there are in Changming. They have all been cleansed and moved ashore these days, but they still have illegal activities in private, which requires them to set up their own operating rooms and prepare doctors.
In this case, there will definitely not be too many doctors, and it may even be said that the fewer the better.
Peng Yue saw that everyone was discussing how to investigate the doctor back then, but he put forward another suggestion, "Is it possible that this doctor was fired from the hospital and disqualified from practicing by the country? If he wants to continue to make money in surgery, For money, you can only go to the black market or work as a black doctor.
Is this also a possibility? "
Zhang Yuqi smiled and nodded, admitting that her idea just now was not comprehensive, "Peng Yu is right. A normal and promising doctor will most likely not participate in an operating room organized by a society.
Those are doctors who are short of money or have questionable conduct, and some who have been fired from the hospital.
Let's investigate these three types. As long as the police support from the Wan Detachment is in place, I think I can see this doctor before getting off work in the afternoon. "
After talking about this topic, Zhang Yuqi asked if anyone else had any other ideas. At this time, Xu Zheng said: "I went back last night to think about this case and established the causes, consequences and process of the murderer's murder." As he said this, he The mobile phone is connected to the big screen via Bluetooth. "Everyone, take a look. I wrote this with my own hand. If there is anything wrong, please discuss it."
Everyone looked at the big screen, which was filled with more than two thousand words, which probably meant Xu Zheng's assumptions about Du Longtao and the others.
To put it simply, Xue Jiaping graduated in July 2023 without taking the postgraduate entrance examination or looking for a job. Then his brother Xue Jiayun opened a mobile phone repair shop for him on Shuyuan Road, University Town, Yiqiao District.
In January 2024, or even longer, Xue Jiaping met Fang Xinhua. Most likely, when he repaired Fang Xinhua's mobile phone, he placed a miniature camera behind the lens of Fang Xinhua's mobile phone, and he also set up a Trojan horse , so Fang Xinhua’s next every move will be under Xue Jiaping’s surveillance.
This hobby of secretly photographing beautiful women is in line with the psychological assessment of Xue Jiaping by various criminal investigation experts. He is introverted, sensitive and has low self-esteem, and likes to pry into other people's privacy.
Xu Zheng guessed that the cause of the eucalyptosis was that Xue Jiaping often met Fang Xinhua by chance, and Fang Xinhua became suspicious. The two might have had a quarrel in the park, or it might be that Xue Jiaping followed Fang Xinhua halfway back to school. Knocked her unconscious.
The specific details of the execution are various. In short, Xue Jiaping killed Fang Xinhua. At this time, it was his first time to kill someone. He should be very hesitant and scared. He should look for the person he trusts most. It should be his brother Xue Jiayun, but His brother is far away in Australia.
Then he could only ask his brother's good friend Du Longtao to help dispose of the body.
It is also possible that Xue Jiaping, who has already had a relationship with Du Longtao, will feel that Du Longtao is his support at that time?
After the first time, there will be a second time, a third time... and the method they used was that Xue Jiaping came forward to flatter the beauty, and then...
Zhang Yuqi looked at the idea written by Xu Zheng, "Maybe what you wrote is not comprehensive. I always feel that there are others involved in this project. For example, people with greater status and power than Du Longtao participated in their game, or helped them deal with it. Follow up."
Xu Zheng asked: "You mean, someone helped them dispose of the body?"
"It should be." Zhang Yuqi was very sure, "Ten years have passed and Wu Mei's body has not been found in Changming. Whether it was buried in the ground or thrown into the lake, it should surface one day. But in this case, there are no clues at all about the victim’s body.
At that time, Xue Jiaping was just a shop owner, Bai Shuting was just Du Longtao's lover, and Du Longtao was just a small leader of the community organization. "
It is indeed possible. Xu Zheng explained his intention in writing this idea, "I think our current investigation is based on the results of inference. So, after we determined that Du Longtao and the others were the murderers, have you considered victimization?" Where will the human remains be?”
"This..." Zhuang Qiang and Peng Yue ran out to play as soon as they got off work these days. They called it a change of mind and a change of thinking. "In the past ten years, our police have almost searched Changming. Didn't the criminal investigation experts say so? , Wumei’s remains were either packed and thrown into the Yangtze River, or they were buried out of the province in other places where they were not easily discovered.”
Lang Shaobai reacted quickly, "Xiao Zheng, do you mean that the body may have been disposed of according to the tradition of the community organization?"
It is impossible for those who run associations without killing people. At this time, they have to dispose of the corpses. Their traditional method of disposing of the corpses is simple and efficient, which is to burn them into a handful of ashes and throw them into any river. There is no evidence of this. Do not stay.
In order to burn the body, their club would need a device that could burn the corpse. The crematorium would definitely not work, that would be a large boiler in a factory. After the smoke-free treatment, no one knew.
However, Changming was already a first-tier city ten years ago, so this kind of boiler definitely could not be used.
Therefore, the community organization has made improvements. One is to use chemicals, and the other is to use ice burial, which is to freeze the body into ice cubes and crush it.
Both methods leave no trace.
However, Gaotian Construction Engineering Group is mainly engaged in real estate equipment and real estate development. It is very easy to dispose of corpses. They can throw them on the foundation and build a building on top. If the building does not collapse, the corpse will not come out, and the corpse may even be mixed into the concrete...
Therefore, Xu Zheng suggested: "It is still necessary to let the anti-hijacking brigade conduct a thorough investigation of Yan Hongqiang's Gaotian Construction Group to find out how Gaotian Group disposed of corpses in 2024.
I have always believed that throwing corpses into the Yangtze River was not a method that a large society like theirs would adopt. "
Zhang Yuqi also felt that throwing it into the Yangtze River and Changming lakes was not as effective as the methods Xu Zheng said. "Gaotian Construction Group, a star enterprise in our city, has many involvements, so our Second Brigade cannot carry out investigations on this group." Investigation, however, because of this case, the anti-hijacking brigade is investigating Yan Hongqiang’s Gaotian Construction Group. I will call after a while and ask them to share the information of Gaotian Construction Group."
Xu Zheng and Lang Shaobai both understood that even though they were criminal police, if they were to investigate the city's star entrepreneurs, they would not be of sufficient weight. Only special investigation teams like the provincial department had such great power.
After discussing the work, everyone had no ink stains. After assigning tasks, each team began to go out to conduct inspections. Xu Zheng just walked downstairs to the open space and felt that the nine o'clock sunshine could kill people.
He looked at Li Wanwan and said, "It's so hot. Go back quickly and follow us out in the field. You, a thin-skinned person like you, will be tanned and red in a day."
Li Wanwan shook her head firmly, "It just so happens that I can go out to work while Sister Meiyue is not around. No one can stop me today."
Zhuang Qiang chuckled and said: "Zheng'er, let her follow. There is a lesbian here. It's okay to meet a female leader in the hospital."
Today, Xu Zheng's team received the task of going to three Grade A hospitals in Hitotsubashi District for investigation, and the remaining hospitals were handed over to the 30 policemen sent by the Wan Detachment.
Ji Meiyue and Wei Yi did not come today. She found a few connections and actually contacted the chef of Bai Shuting's cafe in Xinjiekou Pedestrian Street. No, through the introduction of the chef, her fake My cousin Wei Yi went for an interview at nine o'clock this morning.
Zhang Yuqi asked Ji Meiyue to follow her and asked her to give a gift to the chef. It was not much, two bottles of Jian Nanchun and a piece of Huazi. This increased Wei Yi's interview success by 50%.
Neither Ji Meiyue nor Wei Yi came, and both groups one and two were short of people, so Zhang Yuqi and Li Wanwan joined one group alone. It just so happened that it was more convenient for each group to have a female police officer to do the investigation.
Taikang Hospital was the jurisdiction of Xu Zheng when he worked at Liulihe Police Station. He came here often and was particularly familiar with the security department and medical office here. After arriving here, he took the two of them directly to the medical office.
When he found Director Huang, he explained his intention.
Even though Xu Zheng no longer works at the Liulihe Police Station, Director Huang still remembers him. As soon as they met, he extended his hand to Xu Zheng, "Isn't this Squadron Xu? Long time no see, but I heard that you have been promoted." Yes, you went to the city bureau, right?"
Director Huang's face became tangled as he spoke. He first asked Xu Zheng to follow him into the office and asked in a low voice: "Squadron Xu, do you have any major plans for coming?"
He suddenly remembered that Xu Zheng had been transferred to the Criminal Police Detachment of the Municipal Bureau, which was the department responsible for major criminal cases. Realizing this, he saw that Xu Zheng had not come alone. This posture gave him the feeling that something big was going on. happened.
Xu Zheng smiled quickly and said: "Haha... Director Huang, you are worrying too much. We are here today to ask about the director of surgery of your hospital ten years ago. We need his information."
Director Huang just breathed a sigh of relief when he was pushed back by Xu Zheng, "Commander Xu, did you make a mistake? Dr. Song is an old expert with high medical ethics. How could he commit a criminal case?"
As expected of the leader in charge of the medical department, he was always thinking wildly. Not to mention Xu Zheng, even Zhuang Qiang and Li Wanwan had to admire him. Did the criminal police think that he was also a criminal just after investigating?
"Director Huang, don't worry, we just have some things that require the cooperation of Expert Song." Xu Zheng said quickly, fearing that the director who specializes in doctor-patient relations would be anxious and imaginary, "Don't worry, we are the criminal police of the Municipal Bureau. , We really just need experienced experts to help us break a eucalyptus, which is very important."
The criminal police had to cooperate when they came to the door. After hearing Xu Zheng's assurance, Director Huang finally gave some simple information about Mr. Song.
