At the morning meeting the next day, Zhang Yuqi brought everyone a bad news, except for the fingerprint yesterday, no fingerprints were found in other imprints, and DNA could not be extracted, and the hair found by Captain Yang was tested for DNA, but it was not matched with the relevant personnel of this eucalyptus, and it was not the hostess.

As for whose hair it is, it is estimated that Mr. Xie will have to be asked first, but because it has nothing to do with Ben Yu, Zhang Yuqi did not talk about it.

"Now Wumei's missing eucalyptus can officially list Du Longtao, Xue Jiaping, and Bai Shuting as suspects, and it's hard to say whether there are other suspects. However, the only substantive evidence currently available is a bloody fingerprint of the missing person Ping Mengmeng, and the chain of evidence is relatively thin, so I think it is necessary to follow this clue to investigate.

Ping Mengmeng was injured on the first floor of the sunken, and there were blood marks in the bedroom, which shows that Du Longtao was indeed seriously injured that day, because the bedrooms on the fifth floor of the sinking floor are equipped with anti-noise devices, I have already asked, Du Longtao's neighbors basically have not seen him, nor have they heard any special sounds from his house.

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

On the other hand, re-investigate Ping Mengmeng's life circle, this time focusing on asking the passers-by, Ping Mengmeng's family, relatives, neighbors, friends, etc., to see if they have seen Du Longtao and the three of them, or have seen the scene of these three people getting along with Ping Mengmeng.

Let's add, what else needs to be investigated today? ”

Lang Shaobai frowned, "I've seen the previous investigation of Ping Mengmeng's life circle by the special group, and if I check it again, I have to apply to the 10,000 detachment for police force again."

Will such a big move be known to the suspects? ”

Wumei's missing eucalyptus is relatively influential in Changming, mainly because it was widely spread on the Internet that year, dragging on for two or three years, this eucalyptus was constantly mentioned on the Internet by people with a heart, and the special eucalyptus group was stamped with ironic nicknames such as "straw bag scout" and "not as good as the sweet potato team".

Now that the eucalyptus has been carried out to this extent, more than 200 police officers have been dispatched, and four or five hundred people have been visited and investigated.

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

Although the subjects of the investigation will sign a confidentiality agreement, some people may really take risks for the sake of money.

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

However, yesterday I discussed with several leaders of the Wan detachment that it does not matter whether Xue Jiaping returns to China or not, even if he is absent from the court, only after the verdict is issued, the Ministry of Public Security can start his extradition.

Therefore, let's come at our own pace, the demolition plan has been approved, and at this time, the Ministry of Public Security is also preparing Xue Jiayun's wanted warrant for online fugitives, although it has no real legal effect, but it is enough to block his way back to China. ”

Xu Zheng felt that this should be done, and the second team could not fail to investigate clues for the sake of confidentiality, "I think that if I find the doctor and nurse back then, I may ask for some clues from their mouths." I think this suggestion is very good, but there are forty or fifty hospitals above the second level in Changming, and it is estimated that there are four or five hundred doctors who can do surgery, which also requires a lot of police force. ”

Zhuang Qiang slapped the table, "Since you are not worried about the suspects knowing that we are investigating them, and the leaders also attach importance to them, captain, you can rest assured and boldly make requests to the 10,000 detachments, and it is best to have more police forces, so that we have to go out in person." ”

It's not that the Criminal Police Office can't say that it can't do investigation in the field, but the workload is too large, like Ping Mengmeng's circle of more than 200 people to investigate, and this just relies on the people of the second brigade, and it will take a week at the earliest.

Therefore, at this time, it is much simpler to borrow colleagues from other brother units from the leader to do the investigation.

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

Think about it, what kind of doctor would perform surgery on members of the community?

Visionary societies invest in surgeons when they are still students, but it takes at least 10 years for such surgeons to perform secondary surgery, which is too long.

Therefore, most associations are looking for those who need money urgently, or who have personal shortcomings, such as losing money playing cards or borrowing money that should not be borrowed.

Let's just focus on investigating which hospital surgeons often ask for leave before February 2025 and their medical skills are constantly improving, because there are many members of the community, there must be a lot of surgeries, and the changes in the medical skills of the doctors under them will inevitably not be hidden from the department director. ”

No one knows how many community organizations there are in Changming, they have all been washed and landed ashore these years, but they still have illegal activities in private, which requires them to set up their own operating rooms and prepare doctors.

In this case, the doctor will definitely not be too much, and even say that less is 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 by the state, and if he wants to continue to make money in surgery, he can only go to the black market or become a black doctor."

Isn't this also a possibility? ”

Zhang Yuqi nodded with a smile, admitting that his 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 community.

That is the doctor who lacks money or has a problem with his character, and there are those who have been fired from the hospital.

Let's investigate these three, as long as the police force supported by the 10,000 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 any other ideas, and at this time Xu Zheng said: "I went back last night to think about this eucalyptus, and established the causes, consequences and process of a murderer. Saying that, he connected his mobile phone to the big screen through Bluetooth, "Let's take a look, this is what I wrote by hand, let's discuss anything wrong." ”

Everyone looked at the big screen, which was full of more than 2,000 words, which probably meant that Xu Zheng was imagining Du Longtao and the three of them.

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

In January 2024, or even longer, Xue Jiaping met Fang Xinhua, and he most likely placed the miniature camera behind the lens of Fang Xinhua's mobile phone when he repaired Fang Xinhua's mobile phone, and he also set up a Trojan horse, so Fang Xinhua's every move will be under Xue Jiaping's monitoring next.

This hobby of secretly photographing beauties is very in line with the psychological assessment of Xue Jiaping by various criminal investigation experts, who is introverted, sensitive and inferior, and likes to spy on other people's privacy.

The reason for the eucalyptus hair Xu Zheng guessed that Xue Jiaping could often meet Fang Xinhua by chance, and Fang Xinhua became suspicious, the two may have quarreled in the park, or Xue Jiaping followed Fang Xinhua when he returned to school and knocked her unconscious.

There are various details for the specific actions, in short, Xue Jiaping killed Fang Xinhua, at this time, he should be very hesitant and scared when he killed someone for the first time, and he should be looking for the person he trusts the most, it is said that 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 he feel that Du Longtao is his reliance at that time?

With the first, there will be a second, a third... And the method they used was that Xue Jiaping came forward to hang the beauty, and then...

Zhang Yuqi looked at the eucalyptus idea written by Xu Zheng, "Maybe you didn't write it comprehensively, I always feel that there are still people involved in this eucalyptus, such as people with more status and power than Du Longtao who participated in their game, or helped them deal with the follow-up." ”

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

"It should be." Zhang Yuqi is very sure, "It's been ten years, and the great Changming didn't find Wumei's body, whether it was buried in the ground or thrown into the lake, there should always be a day when it surfaced, but this eucalyptus, the victim's body has no clue 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 the community organization. ”

There is indeed such a possibility, Xu Zheng explained his intention in writing this idea, "I think that our current investigation is based on the results of the reverse extrapolation, so have you considered where the victim's body will be after we determined that Du Longtao is the murderer?" ”

"This..."Zhuang Qiang and Peng Yue ran out to play as soon as they got off work these days, and Mei said that his name changed his mind and his thinking, "In the past ten years, our police have almost searched Changming, didn't the criminal investigation experts say, Wumei's body was either packed and thrown into the Yangtze River, or it was buried in other places that are not easy to be found." ”

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

It is impossible for the community not to kill people, at this time they have to dispose of the corpse, and their traditional method of disposing of the corpse is simple and efficient, that is, burning, burning into a handful of ashes and throwing it into a river, leaving no evidence at all.

And to carry out the fire, their community needs a device that can burn the corpse, and the crematorium is definitely not good, that is, the large boiler of the factory, and after the smokeless treatment, no one knows.

However, ten years ago, Changming was already a first-tier city, and this kind of boiler must not be used.

Therefore, the community organization has made improvements, one is the use of chemicals, and the other is the use of ice burial, that is, the body is frozen into ice and crushed.

Both methods are the same as leaving no trace.

However, Gaotian Construction Engineering Group is mainly engaged in real estate equipment and real estate development, and it is very easy to dispose of the corpse itself.

Therefore, Xu Zheng suggested: "We still have to let the anti-hi brigade conduct a thorough investigation of Yan Hongqiang's Gaotian Construction Engineering Group to find out how Gaotian Group disposes of the corpse in 2024."

I've always believed that throwing corpses into the Yangtze River is not a method that a large community like theirs would use. ”

Zhang Yuqi also felt that throwing into the Yangtze River and Changming lakes was not as good as the methods Xu Zheng said, "Gaotian Construction Engineering Group, a star enterprise in our city, is very involved, so our second team can't investigate this group, however, because of this eucalyptus, the anti-hi team is investigating Yan Hongqiang's Gaotian Construction Engineering, and I will call after a while and ask them to share the information of Gaotian Construction Engineering Group." ”

Xu Zheng and Lang Shaobai both understand that they don't look at them as criminal policemen, if they investigate the star entrepreneurs in this city, the weight is still not good, and only a special investigation team like the provincial department has such great power.

After talking about the work, everyone didn't have ink, and after the assignment of tasks, each team began to go out to investigate, Xu Zheng just went downstairs and walked to the open space, and he felt that the sun at nine o'clock could kill people.

He looked at Li Wanwan, "It's so hot, hurry back, follow us out on the field, you thin skin and tender meat, you will be tanned black and red for a day." ”

Li Wanwan shook his head firmly, "It's just because Sister Meiyue is not here that I can go out on field duty, and no one can stop me today." ”

Zhuang Qiang said with a smile: "Zheng'er, let her follow, there is a female comrade here, and it is also okay to meet the female leader in the hospital." ”

Today, Xu Zheng's group was given the task of going to the three Grade A hospitals in Yiqiao District to conduct investigations, and the rest of the hospitals were handed over to the 30 police forces sent by the 10,000 detachment.

Ji Meiyue and Wei Yi didn't come today, she found a few relationships and really contacted the back kitchen chef of the café opened by Bai Shuting on Xinjiekou Pedestrian Street, no, through the introduction of the chef, let her fake cousin Wei Yi go for an interview at nine o'clock this morning.

Zhang Yuqi asked Ji Meiyue to follow and asked her to give gifts to the chef, not much, two bottles of Jian Nanchun and one Huazi, which increased Wei Yi's interview success by fifty percent.

Ji Meiyue and Wei Yi didn't come, and there was a shortage of people in the first and second groups, so Zhang Yuqi and Li Wanwan joined the group, and it just so happened that it was more convenient for each group to have a female policeman to do the investigation.

Taikang Hospital, which is the jurisdiction of Xu Zheng when he worked at the Liulihe Police Station, he often comes here, and is especially familiar with the security department and medical office here.

When I found Director Huang, I explained my intention.

Don't look at Xu Zheng no longer working at the Liulihe Police Station, this Director Huang still remembers him, as soon as they met, he stretched out his hand to Xu Zheng, "Isn't this Xu Squadron, I haven't seen you for a long time, but I heard that you were promoted and went to the city bureau, right?" ”

Director Huang's face became tangled as he spoke, and he first let Xu Zheng follow him into the office, and asked in a low voice, "Squadron Xu, didn't you come here for any major eucalyptus, right?" ”

He suddenly remembered that Xu Zheng was transferred to the criminal police detachment of the Municipal Bureau, which was the department responsible for major criminal cases, and when he realized this, he saw that Xu Zheng was not coming alone, and this posture gave him a sense that something big had happened.

Xu Zheng hurriedly smiled: "Haha... Director Huang, you are too worried, we are here today to ask about the director of surgery of your hospital ten years ago, and we need his information. ”

Director Huang just breathed a sigh of relief, and was pushed up by Xu Zheng again, "Squadron Xu, are you mistaken?" Dr. Song is an old expert with noble medical ethics, how could he commit a criminal case? ”

is worthy of being the leader in charge of the medical department, and he is thinking crankily all the time in his heart, let alone Xu Zheng, even Zhuang Qiang and Li Wanwan have to admire, could it be that the criminal police just investigated and thought that they were also criminals?

"Director Huang, don't worry, we just have some things that need the cooperation of this old expert Song." Xu Zheng hurriedly said, and he was afraid that the director who specializes in doctor-patient relations would be in a hurry, "Don't worry, we are the criminal police of the Municipal Bureau, and we really just need old experts to help us break a eucalyptus, which is very important." ”

The criminal police had to cooperate when they came to the door, and after hearing Xu Zheng's assurance, Director Huang finally gave a simple information about the old expert Song.
