At seven o'clock in the evening, in the Cuizhuyuan Community, Xu Zheng's team worked overtime temporarily, and he knocked on the door of the first floor of Unit 3 of Building 2 again with the person who checked the traces.

The last time I left a phone, Xu Zheng had already contacted the male owner before he came.

In fact, if it weren't for the urgency of the leader, there would be no need to disturb people at night, but this fingerprint can lock the direct evidence that Ping Mengmeng's disappearance is determined to be related to Du Longtao.

Think of the bloody fingerprints of a missing girl left on the walls of your home, you are not suspicious 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, whether fingerprints can be damaged under the wallpaper without damage, everyone can't wait to know.

If this fingerprint exists, this is direct evidence, if it is damaged, you can only use the photo on the hostess's Douyin short video, this is indirect evidence, of course, such an important eucalyptus is best to have direct evidence.

Also, the leaders also hope that there will be more direct evidence in this room, so when it is almost time to get off work, Director Nie will speak directly and work overtime.

This time, Xu Zheng was ready, because the fingerprint comparison was successful, and the procuratorate approved an online search warrant, which stamped the official seal on the operation.

And he came with sincerity.

Seeing the police comrades coming to the door again, the male and female hosts opened the door very hesitantly and tangled, and after the two sides sat down, Xu took out his documents and search warrants and informed the male owner of the reason for this visit, "At present, we have investigated that the sunken floor and the master bedroom of your house may have the evidence and evidence that our police need, so we need to uncover the wallpaper of your two rooms."

Please rest assured that all losses and compensation will be compensated by our police and will not let you suffer losses.

And because we have to do homework at night, we also ask the lady to take the children to a nearby hotel to rest for the night, and all the expenses are paid by the police.

In addition, the wallpaper is a new one for our police, or is it directly to pay you the amount? ”

Compensation is a must, and the man still wants to be polite, saying no, there is not much money, but this is a procedure and must be gone.

In the end, the couple discussed, let the police pay the money, and they would deal with the rest themselves, as for the damaged quotation, according to Xu Zheng, the wallpaper and labor costs of the two rooms should be truthfully reported to him at that time.

Xu Zheng promised, "Please rest assured, after you report the account, we should transfer the money to you within three working days." ”

The man smiled and nodded, as the owner of the house or when his wife kept pulling his clothes, he staggered his body to block Zhuang Qiang and Ji Meiyue's field of vision, and gave Xu Zheng a red envelope, "Officer Xu, may I ask if our house is a murderous scene?" ”

Xu Zheng discussed this issue with Zhuang Qiang and Ji Meiyue on the way here, although there is no evidence at present to say that this is the first eucalyptus scene, but now the wall with Ping Mengmeng's fingerprints has been splashed with a lot of blood.

Returning the red envelope, Xu Zheng still decided to tell the truth, because these things can't be hidden, and when the eucalyptus is broken, the police will inevitably publicize it to the outside world, so what's the point of hiding it from them now.

"Mr. Xie, at present, the eucalyptus is in the investigation stage, I am not convenient to tell you too much, we have not found any evidence of homicide or other criminal cases in this house, as for the rest, we will not know until the evidence is conclusive."

Mr. Xie clutched the red envelope in his hand tightly, and understood what Xu Zheng meant, and now that he can find evidence here, it means that the police have suspected it, his face suddenly became ugly, Mrs. Xie is similar, and the sinking floor is still their son's residence, which makes them even more worried.

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

It depends on how to say this, urban expansion, many communities are built in former cemeteries, and there is a possibility that some messy things may happen when building houses.

Now Xu Zheng is also practicing forensic medicine, and he doesn't care much about these things, but obviously the Xie family is going to lose sleep tonight.

Since they agreed to the police's arrangement, Ji Meiyue sent Mrs. Xie and their children to a nearby hotel, and Mr. Xie could only stay at home as a live monitor.

The next thing is that the person who checked the trace brought tools into the field, this house was renovated by Du Longtao before, and the walls were painted with latex paint, and later Mr. Xie used high-grade woven wallpaper when decorating, and the glue used was imported plant viscose, which was basically not 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 much, but directly constructed, I think there is a high probability that there is no problem with what you are looking for under the wallpaper." When Mr. Xie saw the police officers who had checked the traces take out the steam engine, he 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, wait and see." ”

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

Xu Zheng and Zhuang Qiang watched the people who were busy here, and I have to say that these people's methods were very professional, in addition to the steam engine, they also took out alcohol spraying cans, hair dryers, salt, and other shovels and tweezers, and the operation steps were even more set.

Xu Zheng really didn't know much about this kind of professional wallpaper removal technique, so he looked at 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 saying that, he felt that it was impossible for these policemen who were obviously technical departments to help him, so he smiled and shook his head and walked out.

After five minutes of working on the steam engine, Captain Yang, who took the lead in the trace inspection, asked Xu Zheng, "Squadron Xu, then we start?" ”

Xu Zheng looked at the camera that was working, "That line Captain Yang, you can do it at your own pace, you also looked at the photo just now at the approximate location of the fingerprints, as long as you ensure that the fingerprints are not damaged, you will be a great achievement." ”

Captain Yang laughed twice, "Don't worry, the decoration materials of the two owners before and after this house are very good, and our craftsmanship in removing wallpaper is no worse than those who are engaged in decoration." ”

Xu Zheng didn't know much about decoration, Zhuang Qiang had been in contact, watching Captain Yang and them use a small shovel to uncover the wallpaper little by little, and spray some alcohol when they encountered a place that was very tightly adhered to the wall...

Zhuang Qiang nodded at Xu Zheng, meaning not to worry.

Said that he was not worried that it was fake, and soon the wallpaper on the gable wall of the door was about to reveal the fingerprint imprint, and everyone's spirit was highly concentrated.

As Captain Yang slowly uncovered the wallpaper, what appeared in front of everyone was a snow-white wall, as well as the unique graininess of latex paint.

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

It wasn't until he saw this scene that Xu Zheng's heart fell, such a large number of traces could no longer be used for DNA testing, but as long as there were fingerprints, it still had the same effect.

Captain Yang took out the blue contrast agent and sprayed it again, and only a quarter of the fingerprints were exposed in front of Xu Zheng and them under the effect of the contrast agent.

This time, 100% real hammer, this fingerprint is Ping Mengmeng, Xu Zheng's mobile phone has high-definition photos processed by the technical department, manual comparison on the spot, 100% is the same.

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

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

Captain Yang was also very happy, "Squadron Xu, what you said is not right, although we have different departments, we are all a family, is it right?" ”

Then they coaxed each other, and a group of people laughed for a long time, Xu Zheng was afraid of disturbing the neighbors, "Captain Yang, you still have to continue to work, check all four walls of this room, including the roof, to see if there are any other fingerprints and dried blood." ”

After he finished speaking, he arranged for Zhuang Qiang to stay here and wait for Captain Yang and them to complete their tasks before going home.

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

The first thing with good news is, of course, to ask the leader for credit, but Xu Zhengneng's only superior is Zhang Yuqi.

At this time, no matter how close he was to the Wan detachment, he couldn't get past his captain.

After hanging up Zhang Yuqi's phone, Xu Zheng finally breathed a sigh of relief, "I've been busy for so long, but I didn't expect the clues to come so inadvertently, and it always feels too easy to be unreal." ”

Ji Meiyue felt that the progress of eucalyptus was too slow, "According to the eucalyptus you have done in the past, this is now the longest time to investigate clues."

In any case, everyone can finally breathe a sigh of relief when this fingerprint is found, which proves that our efforts are in the right direction during this time.

By the way, today I heard that the gang of the Guohe Fugitive Pursuit Office are preparing to return to Beijing in the next two days, so they didn't invite you to take up a temporary post in the Guohe Fugitive Pursuit Office? ”

With Xu Zheng's current qualifications, he is not qualified to be transferred to the National Cooperation Fugitive Pursuit Office, even if their leaders value it, there are two million domestic police, who does not want to be transferred to the Ministry of Public Security, even if it is for further study or "hanging up".

Xu Zheng didn't feel pity, "At best, I can only tremble in Changming, this is also relying on the care of my elders, 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."

Also, I just got married, and Sister Xiaoxin just got pregnant, so I don't want to leave Changming. ”

Ji Meiyue felt that Xu Zheng would also be reluctant to leave Changming, so she said a light-hearted news, "There is another thing you don't think you can think of, I heard that the Provincial Fugitive Pursuit Office was criticized by Chief Ou this time.

Say that they haven't captured as many A and B wanted criminals in the past year as you have captured alone. ”

Speaking of this, Xu Zheng also felt wronged, "Generally, wanted criminals will commit crimes in groups, or participate in community organizations, and it is a coincidence that I arrested those."

It's a pity that the A and B wanted criminals on Changming's side seem to have been caught by me, and we have caught a Jin Weiwei in the past six months. ”

Ji Meiyue, "I see you, you can go to the provincial fugitive pursuit office to work, and if you have the ability, you can arrest the wanted criminals in our province." ”

】

"Sister Mitsuki, don't put a high hat on me, the arrest of wanted criminals mainly depends on luck." Xu Zheng said this, and felt that he still relied on the system, but unfortunately, his system no longer directly located a wanted criminal for him.

And the eucalyptus he is doing now takes a particularly long time, and the system has not sounded for a long time.

Now Xu Zheng is waiting for the final approval of the serial murder eucalyptus of Jingwei and Gao Liying in Suyun City, and now I heard that it is impossible for Teacher Jingwei to admit all of his guilt, and now the eucalyptus is advancing slowly.

By the way, there is also the big star assistant Eucalyptus Death, and the current progress of interrogating Jin Weiwei is not ideal, so Eucalyptus is not counted as a concluded, and the system will not give a reward until they are concluded.

Finally, there is Professor Chi Guoming, who is ninth on the list of hidden killings in the system, Xu Zheng has already guessed what he is advancing, and this matter is not in a hurry.

When these eucalyptus are over, he can get three rewards, and he feels happy when he thinks about Xu Zheng.

Back at the city bureau, Zhang Yuqi was still in the office, and she was relieved that she personally got all the footage of the fingerprint found by the trace inspection, and the fingerprint was found in the video, indicating that it was foolproof.

Looking at the time, it was already half past nine o'clock in the evening, 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 have a look." ”

The leader didn't get off work to go to the eucalyptus scene to work overtime, Xu Zheng didn't have the interest to go home directly, and had to follow Zhang Yuqi to the Cuizhuyuan community.

Now in the room on the lower floor, all four walls of wallpaper have been removed, and the traces are basically painted all over the four walls with blue contrast agent, but unfortunately no useful clues have been found except for a few traces of blood.

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

It looks like it should be an adult woman's hair, but according to my observation, that Mrs. Xie should probably be a person who has no hair. He paused, "Are you trying to ask how I found out?" ”

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

When you look at the bottom of the bed, it's not spotless, but the most conspicuous thing inside is that there is no hair from the hostess, only her hair and the hair of the man..."

Speaking of this, he looked at Zhang Yuqi again and whispered: "According to my experience, I have observed Mrs. Xie, this woman is a charming woman, and she speaks softly with a little clip sound, and the most important thing is her lips.

The fullness of the lips means that there is no dark jungle there, so I think there is a high probability that this hair belongs to another woman, and it is still in the crack of the wardrobe track, so I think it may be missing. ”
