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

Chapter 470 Specialization in Trace Inspection

At [-]:[-] p.m. in Cuizhuyuan Community, Xu Zheng's team worked overtime temporarily, and he brought the trace inspectors to knock on the door on the first floor of Unit [-], Building [-] again.

The last time I left a phone number, Xu Zheng had already contacted the host before coming.

In fact, if the leader hadn't been in a hurry, there would be no need to bother people at night, but this fingerprint can pinpoint the direct evidence that Ping Mengmeng's disappearance is definitely related to Du Longtao.

Think of a missing girl's bloody fingerprints left on the wall of your house, you don't suspect who is suspicious.

With this evidence, Du Longtao can be directly arrested.

It can be seen that the leaders attach great importance to fingerprints, but after ten years, everyone can't wait to know whether fingerprints can be under the wallpaper without damage.

If this fingerprint exists, it is direct evidence. If it is damaged, you can only use the photo on the short video of the hostess Douyin. This is indirect evidence. Of course, it is best to have direct evidence in such an important case.

Also, the leaders hoped that there would be more direct evidence in this room, so when it was almost time to get off work, Director Nie spoke directly, and overtime work was also needed to find out.

This time, Xu Zheng was well prepared for the door-to-door visit. Because the fingerprint comparison was successful, the procuratorate approved an online search warrant, which sealed the operation.

And he came with sincerity.

Seeing the police comrades coming to the door again, the host and hostess opened the door hesitantly and entangled. After the two parties were seated, Xu took out his ID and search warrant and told the host the reason for this visit. The first floor of Shen and the master bedroom may contain evidence and evidence that our police need, so we need to uncover the wallpaper of your two rooms.

Also, please rest assured that our police will compensate for all losses and compensations, and you will not suffer losses.

And because we have to work at night, we also asked the lady to take the child to a nearby hotel to rest for the night, and the police paid all the expenses.

In addition, is the wallpaper replaced by our police, or should we pay you directly? "

Compensation is necessary, and the male host wanted to be polite and said no, there is not much money, but this is a procedure and must go.

In the end, the husband and wife had a discussion, and it was enough for the police to pay the money, and they would handle the rest themselves. As for the damaged quotation, according to Xu Zheng's statement, it was enough to report the wallpaper and labor costs of the two rooms to him truthfully.

Xu Zheng promised, "Please don't worry about one thing. After you report the account, we should transfer the account to you within three working days."

The male owner smiled and nodded. As the owner of the house, he staggered his body to block the view of Zhuang Qiang and Ji Meiyue while his wife kept pulling his clothes, and stuffed Xu Zheng a red envelope, "Xu Zheng Police officer, may I ask if our house is a murder scene?"

Xu Zheng discussed this issue with Zhuang Qiang and Ji Meiyue on the way here. Although there is no evidence to say that this is the first crime scene, the wall with Ping Mengmeng's fingerprints has been spattered a lot blood.

After returning the red envelope, Xu Zheng still decided to tell the truth, because these things cannot be concealed, and when the case is solved, the police will inevitably publicize it to the outside world, so what's the point of hiding it from them now.

"Mr. Xie, the case is currently under investigation. It is inconvenient for me to tell you too much. We have not found any evidence of murder or other criminal cases in this house. As for the others, we will not know until the evidence is conclusive. "

Mr. Xie tightly clutched the red envelope in his hand, and understood what Xu Zheng meant. Now that he could find evidence here, it meant that the police had already suspected him. His expression suddenly became ugly, and Mrs. Xie was similar. Where their son lives, this worries them even more.

Seeing that they were sad, Xu Zheng didn't say anything to comfort them.

How to say this thing, the city expands, many communities are built in the former cemetery, and some messy things may happen when the house is built.

Now that Xu Zheng is also studying forensic medicine, he himself doesn't care much about these things, but obviously the Xie family and his wife are going to suffer from insomnia tonight.

Now that they agreed to the police's arrangement, Ji Meiyue sent Mrs. Xie and their children to a nearby hotel. As for Mr. Xie, he could only stay at home as a living monitor.

Next, the trace inspectors brought tools into the venue. This house was renovated by Du Longtao before, and the walls were painted with latex paint. Later, Mr. Xie used high-grade woven wallpaper when decorating. The glue is imported plant glue, which is basically non-corrosive to the wall.

"Officer Xu, I remember that when we were renovating three or four years ago, those masters didn't clean up the wall, but directly constructed it. I think there is a high probability that what you are looking for under the wallpaper is no problem." Mr. Xie looked The police who arrived at the trace inspection took out the steam engine and knew that they were going to remove the wallpaper.

Xu Zheng nodded, "To be honest, we definitely want the things under the wallpaper to be undamaged. Let's wait and see."

The main purpose of the steam engine is to heat and moisten the wallpaper, so that it will not damage the wall as much as possible when the wallpaper is removed later.

Xu Zheng and Zhuang Qiang watched the trace inspectors busy here, and they had to say that these people were very professional in their techniques. In addition to the steam engine, they also took out alcohol spray cans, hair dryers, salt, and various other shovels and tweezers to operate The steps are set in a set.

Xu Zheng really didn't understand this professional technique of removing wallpaper, so he took it very seriously at this time.

Even Mr. Xie was a little moved at this time, "Officer Xu, your colleagues are very professional, can we buy wallpaper, and you can help paste it?"

After speaking, he felt that these policemen from the technical department could not help him, so he smiled and shook his head and walked out.

The homeowner's going out did not affect the people of the trace inspection to continue working. After working on the steam engine for 5 minutes, Captain Yang, the leader of the trace inspection, asked Xu Zheng, "Squadron Xu, shall we start?"

Xu Zheng looked at the camera at work, "Captain Yang, you can follow your own pace. You have seen the photo of the approximate location of the fingerprints just now. As long as you ensure that the fingerprints are not damaged, you can do a great job."

Captain Yang laughed twice, "Don't worry, the two previous owners of this house used very modest materials for decoration, and besides, our technique of peeling off the wallpaper is no worse than those who do the decoration."

Xu Zheng didn't know much about decoration, but Zhuang Qiang had been in contact with it before. He watched Captain Yang and the others use a small shovel to remove the wallpaper little by little, and spray some alcohol on places that were tightly adhered to the wall...

Zhuang Qiang nodded to Xu Zheng, meaning there is no need to worry.

It was a lie to say that they were not worried about it, and soon the wallpaper on the gable wall at the entrance was about to reveal the fingerprints, and everyone's spirits were highly concentrated.

As Captain Yang slowly removed the piece of wallpaper, what was presented to everyone was a snow-white wall with the unique graininess of latex paint.

However, everyone was mentally prepared for this situation. Captain Yang took out the blood trace form agent from his bag and sprayed it lightly on the wall. After a while, a mark the size of a grain of rice really appeared on the wall.

It wasn't until he saw this scene that Xu Zheng's heart sank. Such faint traces can no longer be tested for DNA, but as long as there are fingerprints, it will still have the same effect.

Captain Yang took out the blue contrast agent and sprayed it on. Only a quarter of the fingerprints were exposed in front of Xu Zheng and the others under the action of the contrast agent.

This time, it was 100% confirmed. This fingerprint belonged to Ping Mengmeng. Xu Zheng had a high-definition photo processed by the technical department in his mobile phone. After manual comparison on the spot, it was 100% the same.

"Captain Yang, and brothers, thank you so much today." Xu Zheng was very happy to get this fingerprint at the scene, because there was finally direct evidence for Wumei's disappearance.

Fortunately, after more than 20 days of painstaking investigation, this case finally has substantial evidence, which is not easy.

Captain Yang was also very happy, "Squadron Xu, what you said is wrong. Although we have different departments, we are all one family. Isn't that right?"

Xu Zheng was afraid of disturbing the neighbors, "Captain Yang, you have to continue working. Check all four walls of this room, including the roof, to see if there are any other fingerprints and signs." Dried blood."

After he finished speaking, he arranged for Zhuang Qiang to stay here and wait for Captain Yang and the others to complete their mission before returning home.

As for himself, he called Ji Meiyue, who had just returned from the hotel, and rushed towards the city bureau.

The first thing to do when there is good news is of course to ask the leader for credit, but the only superior Xu Zhengneng reports to is Zhang Yuqi.

At this time, no matter how close he was to Team Wan, he could not surpass his captain.

After hanging up Zhang Yuqi's phone call, Xu Zheng finally breathed a sigh of relief, "I've been busy for so long, but I never thought that the clues would come in this way inadvertently. It always feels too easy and unreal."

On the contrary, Ji Meiyue felt that the progress of the case was too slow, "According to the cases you have handled in the past, this is the longest investigation clue.

In any case, everyone can finally breathe a sigh of relief after finding this fingerprint, which proves that our efforts during this period are in the right direction.

By the way, today I heard that the people from the Guohe Escapement Office are planning to return to Beijing in the next two days, so they didn't invite you to the Guohe Escapement Office? "

With Xu Zheng's current qualifications, he is simply not qualified enough to join the National Cooperative Escape Investigation Office. Even if their leaders value him, there are 200 million domestic police officers. Who would want to be transferred to the Ministry of Public Security, even if it is for further study or "listing".

Xu Zheng didn't feel sorry, "At best, I can only shake my head in Changming. This is also dependent on the elders to take care of me. There are too many capable people in this world, and there are many people who have more credit than me. I didn't think about it at all. Pass.

Also, I just got married, and sister Xiaorui is just pregnant, so I don't want to leave Changming. "

Ji Meiyue felt that Xu Zheng would also be unwilling to leave Chang Ming, so she talked about some light news, "There is one more thing that you may not expect, I heard that the Provincial Office of Chasing Escapes was named and criticized by Chief Ou this time.

Say they have caught more A and B wanted criminals than you alone in the past year. "

Speaking of this, Xu Zheng also felt wronged, "Generally wanted criminals will group together to commit crimes, or join social organizations, and it's just a coincidence that I caught those.

It's a pity that I seem to have caught all the wanted criminals A and B on Changming's side. We have caught Jin Weiwei in the past six months. "

Ji Meiyue smiled, "I see you, you can go to the province to chase and do work, and if you have the ability, you can arrest the wanted criminals in our province."

"Miss Meiyue, don't give me too much credit. Catching wanted criminals is mainly based on luck." Xu Zheng said this, thinking that it still depends on the system. Unfortunately, his system no longer directly locates wanted criminals for him.

Moreover, the case he is handling now takes a very long time, and the system has not rang for a long time.

Now Xu Zheng is waiting for the final approval of the serial murder case of Jing Wei and Gao Liying in Suyun City. He heard that it is impossible for Teacher Jing Wei to plead guilty to all of them. Now the progress of the case has slowed down.

By the way, there is also the case of the death of a superstar assistant. The current interrogation of Jin Weiwei is not progressing satisfactorily, so the case is not considered closed, and the system will not reward them until they are closed.

Finally, there is Professor Chi Guoming, who is No.9 in the hidden killing list of the system. Xu Zheng has already guessed what he is advancing, and there is no rush for this matter.

When these cases are over, he can get three rewards. Just thinking about Xu Zheng makes him happy.

Back at the Municipal Bureau, Zhang Yuqi was still in the office, and she was relieved when she got all the video footage of the fingerprint inspection and found the fingerprint. This fingerprint was found in the video, which shows that it is safe now.

Looking at the time, it was already 09:30 late, Zhang Yuqi first called Wan Haihong to report the good news, and then said to Xu Zheng and Ji Meiyue: "It's so late, you two get off work first, I'll go to the scene to see. "

The leader didn't get off work and had to go to the scene of the crime to work overtime. Xu Zheng didn't have the interest to go home directly, so he had no choice but to follow Zhang Yuqi to the Cuizhuyuan Community.

In the room on the first floor, the wallpaper on the four walls has been removed, and the trace inspection basically covered the four walls with blue contrast agent. Unfortunately, except for a few traces of blood, no other useful clues were found. .

However, Captain Yang found a curvy hair in the gap of the wardrobe track in the master bedroom on the first floor. After Zhang Yuqi and Xu Zheng arrived, he closed the door and said, "You guys, this hair was found in the gap of the wardrobe track door.

It looks like it should be the hair of an adult woman, but according to my observation, that Mrs. Xie probably has no hair at all. He paused, "Do you want to ask me how I found out?" "

He pointed to the wardrobe and the bottom of the bed, "Mrs. Xie and the others didn't renovate the wardrobe when they redecorated it, they just changed the bed and wallpaper.

Look at the bottom of the bed, it is not spotless, but the most conspicuous thing inside is that there is no hair of the hostess, only her hair and the hair of the host..."

Having said that, he looked at Zhang Yuqi again, and said in a low voice: "According to my experience, I have observed Mrs. Xie, this woman is naturally charming, she speaks softly with a little clip sound, the most important thing is her lips.

Full lips correspond to the fact that there is no dark jungle there, so I think there is a high probability that this hair belongs to other women, and it is still in the crack of the wardrobe track, so I think it may belong to the missing person. "
