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

Chapter 471 Next Step

In the morning meeting the next day, Zhang Yuqi brought a bad news to everyone. Except for the fingerprint yesterday, no fingerprints were found in other imprints, and DNA could not be extracted. The hair found by Captain Yang was tested for DNA, but It did not match with the relevant personnel in this case, nor did it belong to the hostess.

As for who the hair belonged to, it is estimated that Mr. Xie should be asked first. However, because it has nothing to do with this case, Zhang Yuqi did not talk about it.

"Now the case of Wumei's disappearance can officially list Du Longtao, Xue Jiaping, and Bai Shuting as suspects. As for whether there are other suspects, it is hard to say. However, the actual evidence currently available is only a blood of the missing person Ping Mengmeng." Fingerprints, the evidence chain is relatively weak, so I think it is necessary to follow this clue to investigate.

Ping Mengmeng was injured on the first floor of the sinking, and there were blood marks in the bedroom, which shows that Du Longtao was indeed seriously injured that day, because the bedrooms on the first floor of the sinking 5 were equipped with anti-noise devices. I have already asked, and Du Longtao's neighbors basically I haven't seen him, and I haven't heard any special sounds from his house.

In this case, I suggest that we investigate the doctors and nurses who operated on Du Longtao on the one hand.

On the other hand, re-investigate Ping Mengmeng's life circle, this time focusing on asking passers-by, Ping Mengmeng's family members, relatives, neighbors, friends, etc. who were questioned back then, to see if they have seen Du Longtao and the other three, or seen this The scene of the three of them getting along peacefully and cutely.

Let me add, what else needs to be investigated today? "

Lang Shaobai frowned, "I've seen the investigation of Ping Mengmeng's life circle by the task force before, and if we do the investigation again, we have to apply to the Wan Detachment for police force.

Will such a big movement be known by the suspect? "

The case of Wumei's disappearance is considered to have a relatively large influence in Changming, mainly because it was widely spread on the Internet and dragged on for two or three years. "Idiot Scout", "Not as good as the Sweet Potato Team" and other homophonic stalks with ironic nicknames.

Now that the case has progressed to this level, a total of more than 200 police officers have been mobilized, and 500 people have been visited and investigated. If this is the investigation of Wumei's life circle, more police forces will be mobilized.

Lang Shaobai was worried that Du Longtao, and even Xue Jiaping, would know about such a big movement. If he knew, Xu Zheng's plan would be difficult to carry out.

Although the investigation objects will sign a non-disclosure agreement, some people may really take risks for money.

Zhang Yuqi obviously thought of this question, "This is unavoidable, as long as we reopen the case, people like Bai Shuting or her husband Yan Hongqiang will know that we are investigating Du Longtao sooner or later.

However, yesterday I had a discussion with several leaders of the Wan Detachment. Whether Xue Jiaping will return to China is not important. Even if he does not appear in court, the Ministry of Public Security can initiate his extradition only after the verdict is issued.

So, let's go at our own pace. The demolition plan has been approved by Wan Detachment. At this time, the Ministry of Public Security is also preparing Xue Jiayun's Internet fugitive arrest warrant. Although it has no real legal effect, it is enough to stop him from returning to China. "

Xu Zheng felt that this was the way it should be done, and the Second Brigade couldn't just keep the secrets secret. "I think that if we find the doctor and nurse back then, we might get some clues from them. There is also the question from Wanwan yesterday. When the department directors of the major hospitals checked it out, I think this suggestion is very good. However, there are forty or fifty hospitals above the second grade in Changming, and it is estimated that there are four to five hundred doctors who can perform surgical operations, which requires a lot. police force."

Zhuang Qiang slapped the table, "Since you don't worry about the suspect knowing that we are investigating them, and the leaders also pay attention to it, Captain, you can safely and boldly make demands on the Wan Detachment. It is best to have more police force, so that we don't have to go out in person. field work."

The criminal police handling the case is not to say that they can't do field investigations, but that the workload is too large. For example, there are more than 200 people in Ping Mengmeng's circle of people to investigate. It will take a week at the fastest with just a few people from the second brigade.

Therefore, at this time, it is much easier to ask the leader to borrow colleagues from other brother units for investigation.

Zhang Yuqi felt that there was no need for too many police forces, "Surgeons are not general practitioners, many doctors are proficient in one category.

Think 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, but it takes at least ten years for such surgeons to perform secondary surgery, which is too long.

Therefore, most clubs are looking for those who are in urgent need of money, or who have personal moral disadvantages, such as losing money playing cards or borrowing money that should not be borrowed.

We only need to focus on investigating which hospital's surgeons often ask for leave but their medical skills are constantly improving before February 2025. Because there are many members in the club, there must be many surgical operations, and the changes in the doctors' medical skills must not be hidden from the director of the department. "

No one knows how many social organizations there are in Changming. They have been cleaned up and landed ashore these years, but they still have illegal activities in private, so they need to set up operating rooms and prepare doctors by themselves.

In this case, the doctor will definitely not have too many, or even say the less 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 by the hospital and disqualified by the state. If he wants to continue to make money in surgery If you don’t have money, you can only go to the black market or work as a black doctor.

Is this also a possibility? "

Zhang Yuqi nodded with a smile, admitting that her thoughts just now were not comprehensive, "What Peng Yu said makes sense, a normal and promising doctor will most likely not participate in the operating room organized by the society.

That is doctors who are short of money or have bad conduct, and those who have been expelled from the hospital.

Let's investigate these three types. As long as the police force supported by the Wan Detachment is in place, I think I can see this doctor before I get off work in the afternoon. "

After talking about this topic, Zhang Yuqi asked if other people had other ideas. At this time, Xu Zheng said: "I went back last night to think about this case, and established the ins and outs and process of the murderer's crime." Bluetooth connected to the big screen, "Let's take a look, this is written by myself, if there is anything wrong, let's discuss it."

Everyone looked at the big screen, which was filled with more than 2000 characters, which roughly meant Xu Zheng's idea of ​​committing crimes against Du Longtao and the other three.

To put it simply, Xue Jiaping graduated in July 2023, did not take the postgraduate entrance examination, and did not find a job. Then his brother Xue Jiayun set up a mobile phone repair shop for him on Shuyuan Road, University Town, Yiqiao District.

In January 2024, or even longer, Xue Jiaping got to know Fang Xinhua. Most likely, he put a tiny camera behind the lens of Fang Xinhua's phone when he repaired Fang Xinhua's phone. In addition, he also set up a Trojan horse , so Fang Xinhua's next move will be under Xue Jiaping's surveillance.

This hobby of secretly taking pictures of beautiful women fits well with the psychological evaluation of Xue Jiaping by various criminal investigation experts. He is introverted, sensitive and inferior, and likes to spy on other people's privacy.

The reason for the incident, Xu Zheng guessed, was that Xue Jiaping often ran into 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 out.

The specific rules of the crime are various. In short, Xue Jiaping killed Fang Xinhua. At this time, he should be very hesitant and afraid to kill Fang Xinhua for the first time. He should find the person he trusts the most. Ordinarily, it should be his brother Xue Jiayun, but he Brother is far away in Australia.

Then he could only ask his brother's good friend Du Longtao to help him dispose of the corpse.

It's also possible that Xue Jiaping, who has already had a bond with Du Longtao, will feel that Du Longtao is his reliance at that time?
Once there is the first time, there will be the second time, and the third time. The method they used was that Xue Jiaping came forward to tease the beautiful woman, and then...
Zhang Yuqi looked at the case scenario written by Xu Zheng, "Maybe you didn't write comprehensively, I always feel that there are still people involved in this case, for example, people with greater status and rights than Du Longtao participated in their game, or helped them handle it." Follow up."

Xu Zheng asked: "You mean, someone helped them dispose of the corpse?"

"It should be." Zhang Yuqi was very sure, "It's been ten years, and the huge Changming has not found Wumei's body. Whether it was buried in the ground or thrown into the lake, it must surface one day. But in this case, the victim's body has no clues at all.

Back then, Xue Jiaping was just a shop owner, Bai Shuting was just Du Longtao's lover, and Du Longtao was just a small leader of a social organization. "

There is indeed such a possibility. Xu Zheng explained his intention for writing this idea, "I think our current investigation is based on the results and reversed, so have you considered victimization after we judged Du Longtao and the others as the murderers?" Where will the human remains be?"

"This." Zhuang Qiang and Peng Yue ran out to play after get off work these days, pretending to change their minds and ideas, "In the past ten years, our police have almost searched Changming. Didn't the criminal investigation experts say that five Mei’s remains were either packed and thrown into the Yangtze River, or they were buried outside the province and buried in other places where it would not be easy to find.”

Lang Shaobai reacted quickly, "Xiaozheng, what do you mean, the corpse may have been disposed of according to the tradition of the community organization?"

It is impossible for those who engage in associations not to lose their lives. At this time, they have to dispose of the corpses. Their traditional method of disposing of corpses is simple and efficient. Do not stay.

And to carry out the incineration, their association needs a device that can burn the corpse. The crematorium will definitely not work, that is the large boiler of the factory, and no one will know after the smoke-free treatment.

However, Changming was already a first-tier city ten years ago, and this kind of boiler must 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 corpse into ice cubes and crush them.

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 the corpse itself. Throw it on the foundation and build a building on it. The building will not collapse and the corpse will not come out, and the corpse will even be mixed into the concrete.
Therefore, Xu Zheng suggested: "It is still necessary to let the anti-hey brigade conduct a thorough investigation of Yan Hongqiang's Gaotian Construction Engineering Group, and find out how Gaotian Group handles the corpse in 2024.

I have always believed that throwing corpses into the Yangtze River is not the method that a large society like theirs would adopt. "

Zhang Yuqi also felt that throwing them into the Yangtze River and Changming lakes was not as effective as the methods Xu Zheng said, "Gaotian Construction Engineering Group, a star enterprise in our city, has a lot of involvement, so our second brigade cannot conduct investigations on this group. Investigation, however, because of this case, the Anti-Hey Brigade is investigating Yan Hongqiang's Gao Tian Construction Engineering, and I will call after a while and ask them to share the information of Gao Tian Construction Engineering Group."

Both Xu Zheng and Lang Shaobai understood that even though they were criminal police officers, if they were to investigate the city's star entrepreneurs, they would still not have enough weight, and only a special investigation team like the provincial department had such great power.

After talking about work, there was no ink marks on everyone, and after assigning tasks, each team started to go out to do investigations. As soon as Xu Zheng went downstairs and walked to the open space, he felt that the nine o'clock sun could burn people to death.

He looked at Li Wanwan, "It's so hot, go back quickly, and follow us to the field, you skinny and tender, you'll be black and red in the sun all day."

Li Wanwan shook his head resolutely, "I can only go out to work when Sister Meiyue is not around. No one can stop me today."

Zhuang Qiang said with a chuckle: "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 was given the task of going to the three first-class hospitals in Yiqiao District for investigation, and the rest of the hospitals were handed over to the [-] policemen sent by the Wan Detachment.

Ji Meiyue and Wei Yi didn't come today. She found a few contacts and actually got in touch with the head chef of Bai Shuting's coffee shop in Xinjiekou Pedestrian Street. No, through the chef's introduction, her fake Cousin Wei Yi went to the interview at nine o'clock this morning.

Zhang Yuqi asked Ji Meiyue to follow along, and asked her to give the chef a gift, not many, two bottles of Jiannanchun and one Huazi, which increased Wei Yi's interview success by [-]%.

Ji Meiyue and Wei Yi didn't come, and both the first and second groups were short of people, so Zhang Yuqi and Li Wanwan joined the group alone. It happened to be more convenient for each group to have a policewoman to do the investigation.

Taikang Hospital was the area under the jurisdiction of Xu Zheng when he was working at the Liulihe Police Station. He often came here and was very familiar with the security department and medical department here. After arriving here, he took the two of them directly to the medical department.

When he found Director Huang, he explained his purpose.

Regardless of the fact that Xu Zheng is no longer working at the Liulihe Police Station, Director Huang still remembers him. He reached out his hand to Xu Zheng after seeing each other, "Isn't this Xu Squadron? Long time no see. I heard that you were promoted. It’s time to go to the city bureau, right?”

Director Huang's expression became tangled as he spoke, first let Xu Zheng follow him into the office, and asked in a low voice, "Squadron Xu, you guys have some serious case here, right?"

He suddenly remembered that Xu Zheng had been transferred to the Criminal Police Detachment of the City Bureau, which is the department in charge of major criminal cases. Realizing this, he saw that Xu Zheng was not here alone. This posture gave him a feeling that something serious was happening. up.

Xu Zheng quickly smiled and said, "Haha. Director Huang, you are overthinking. We are here today to inquire about the surgical director of your hospital ten years ago. We need his information."

Just as Director Huang breathed a sigh of relief, he was pushed up again by Xu Zheng, "Squadron Xu, did you make a mistake? Old Doctor Song is an old expert with noble 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. Could it be that the criminal police thought he was also a criminal just after investigating?

"Director Huang, don't worry, we just need the cooperation of this old expert Song." Xu Zheng said hastily, fearing that the director who specializes in doctor-patient relations would be impatient, "Don't worry, we are criminal police from the Municipal Bureau , really just need old experts to help us solve a case, which is very important.”

The criminal police had to cooperate when they came to the door. Hearing Xu Zheng's assurance, Director Huang finally gave the simple information of old expert Song.
