By the time Xu Zheng and the others rushed back to the criminal police brigade with a smell, the relevant test results had come out.

A bad news, in addition to proving that this was used by the murderer, there are no other clues to what was fished out of the bucket, if there is, it is to check the source of the mask and gloves, but this is undoubtedly looking for a needle in a haystack.

The good news is that the plastic bag found at the base of the wall wrapped the clothes, and not only a man's fingerprints were extracted from the plastic bag.

There are also on clothes, but only fingerprints, without any hair or dander or nails carrying DNA.

However, this good news is not easy to say at the moment, because it is not certain that this jacket was left by the murderer.

The first thing Lu Shen did when he came back was to ask people to search the fingerprint in the fingerprint library to see if they could compare it, as expected, as long as the Chinese people have ID cards, they can find out who the owner of this fingerprint is.

Zheng Jun, aged 31, native of Pingjiang Province, ID card address: No. 72, Matian Road, Tiexinqiao Street, Yuhuatai District, Changming, Ming'an Community

This address is less than five kilometers away from Mak Jingwei's home, and the relationship between the two should be more than just one case and two murderers.

I should have known each other before, but I can't figure it out if it's either a classmate or a friend.

After Lu Shen got the news, he quickly asked people to check Zheng Jun's mobile phone number and locate his location.

But soon, his colleagues reported, "Brigade Lu, at present, the two mobile phone numbers under Zheng Jun's name cannot be located, and the SIM card cannot be read, so the card should be pulled."

And the last call on his mobile phone showed that he had been turned off for three days.

Also, his two mobile phone numbers have no record of contacting Mai Jingwei and Mi Yu. ”

A colleague who investigated the means of transportation under Zheng Jun's name then reported, "Zheng Jun's name, no, he doesn't have a car under his name, but he usually drives a black Tesla with a flat license plate A3698F.

The owner of the car is his father's name, Zheng Dongshan.

The Tianyan system showed that the car was parked in the parking space outside his community and had not been touched for a week. ”

"It seems that this Zheng Jun has a very strong anti-reconnaissance ability." Lu Shen instructed again: "You check his relationship with Mai Jingwei again, starting from elementary school, no, starting from kindergarten, check their school records." ”

He named a squadron leader under their criminal police brigade again, "Lao Yang, you lead the team to go to the Ming'an community quickly."

At the same time, notify the community staff where the Ming'an community is located, as well as the police station in the jurisdiction, and ask them to send someone to assist you in investigating this Zheng Jun's social relations.

After you get there, first check whether he is hiding at home, focusing on whether Mak Jingwei is there. ”

After Lu Shen finished arranging, he asked Xu Zheng again, "Do you think I have something inappropriate?" ”

Xu Zheng thought about it for a while, before Lu Shen's investigation of Mai Jingwei's social relations, his relatives, friends, classmates and colleagues had all checked, and it seemed that there was no such person named Zheng Jun.

But now that this person suddenly appeared, it was very suspicious, not to mention the relationship between the two, let's just say that they are the same age and live not far from home, it cannot be ruled out that they have a small relationship.

But if it's really small, why can't you find it before?

"Brigade Lu, should we investigate Zheng Jun's family relationship again, maybe he knows that it is easy to be located with his mobile phone number, so will he use his wife's or other people's mobile phone number?"

Lu Shen thought about it and immediately arranged for his colleagues to investigate this.

At this time, the colleague who had just investigated Zheng Jun's mobile phone number reported again: "Brigade Lu, Zheng Jun has no criminal record, but he is a dishonest person enforced by the court, and the bank card, WeChat and Alipay in his name have not made money transactions for three years."

In addition, he does not have any property in his name, and the title deed of the house in the Ming'an community is in his mother's name. ”

"You check his wife's situation, is she also a dishonest person?" Lu Shen asked.

"No, the household registration information shows that Zheng Jun and his wife have been divorced for three years, and the two have a daughter and are now living with the woman.

I also found out that Zheng Jun cut off the unfinished building in Xinhuamen Community, Yuhuatai District in October 2032, and he should have divorced his wife before the confession. ”

If the supply of unfinished buildings is cut off, the bank will still sue if the negotiation fails.

No wonder Zheng Jun will become a dishonest person, not to mention bank card transactions, he can't even receive WeChat red envelopes.

In this case, how can he still use bank cards, WeChat, Alipay and other third-party transactions.

Even, he can't use the bank cards of relatives and friends to make transactions, which is illegal.

Of course, this is the case, but in fact, there are too many dishonest people who have become dishonest in China, and the police and banks cannot fully supervise the use of other people's mobile phone numbers and bank cards for transactions.

Because there are so many of them.

In this way, it will be difficult to find out whose mobile phone number and bank card Zheng Jun usually uses in a short time.

Xu Zheng lowered his head and pondered, could it be that Zheng Jun became a dishonest person because the house was cut off, and he couldn't make money, so he thought about stealing Mi Yu's money.

But this is impossible, because on the day of the crime, Mi Yu's family did not lose money and jewelry.

Then why did Zheng Jun appear at the scene of the crime, could it be that he had a grudge against the deceased?

The more Xu Zheng thought about it, the more he felt that the death of the deceased should not be as simple as Mai Jingwei going home to find his lover and killing him in anger, "Brigade Lu, do you say that this is possible, I remember that you checked before, and Mai Jingwei returned to the country a day in advance."

When he called Mi Yu and transferred money, he was already in Yuhuatai.

Then he went straight home and saw the deceased in bed with his wife.

Although according to Mi Yu, she was excited to receive the transfer, and her husband was coming back soon, she wanted to save money with her lover for the last time a year ago, so she drove out to bring the deceased home.

But the question is, why did Mai Jingwei come back early, did he already know that Mi Yu was cheating, why did everyone go to China and transfer money to Mi Yu, why didn't he knock on the door but went home over the wall?

Look at it now, did you say that Zheng Jun reported it to him? ”

"You mean to say that Mak Jingwei asked Zheng Jun to help find out if his wife was having an affair?" Lu Shen thought down Xu Zheng's train of thought, "This help shouldn't be free, right?"

If the two are still friends, whether it is for the morality of friends or for money, Zheng Jun has no reason not to agree.

It's just how did he get in touch with Mak Jingwei?

We checked all the calls and chat records of Mak Jingwei after returning to China, and found nothing suspicious. ”

It took about more than ten hours to take a plane back from North Africa, and Xu Zheng thought of a possibility, "You said that we can reason as policemen, so can Zheng Jun, who has strong anti-reconnaissance capabilities, also reason?"

For example, after the two of them met, it was he who asked Mai Jingwei to call Mi Yu, and guessed that Mi Yu would definitely contact the deceased after hanging up her husband's phone, and then pick up the deceased to come to the house to cheat. ”

Gu Jia and Zhuang Yongshan were not sent out to carry out the mission this time, after listening to Xu Zheng's analysis.

Zhuang Yongshan expressed his opinion, "Director, Brigade Lu, is it next, Mai Jingwei jumped in, and in a fit of anger, he hit the deceased with a stick on the back of the head, and knocked Mi Yu unconscious.

And he ran out.

Then he told Zheng Junyi that he felt uneasy, so he made up for the deceased with another stick, and blood was splashed on his body, so he wiped it with Mi Yu's underwear, and finally disposed of the things on his body when he left. ”

Xu Zheng nodded, "Judging from the scene of the crime, this is indeed a possibility, but the location of Zheng Jun and Mai Jingwei has not yet been locked, where can these two people hide?" ”

Gu Jia looked at the satellite map of Yuhuatai District, and suddenly pointed to the unfinished community of Xinhuamen, "You say, will the two of them hide here, I think Zheng Jun should be very familiar with this unfinished building." ”

Every owner of an unfinished building must be dreaming that the construction site can continue to start, and will definitely pay attention to it often, and even go around inside, at present, this place is indeed a good place for them to hide.

"Whether they're hiding here or not, let's send someone to check first." Lu Shen looked at the colleagues who were still in the conference room, and named several of them, including Gu Jia and Zhuang Yongshan, and asked them to take people to the unfinished building, Zheng Jun's parents and ex-wife's house respectively.

After arranging, he asked people to continue to investigate Zheng Jun's social relations.

Just as Lu Shen wanted to continue discussing with Xu Zheng where the two suspects would hide, he found that he walked up to his busy colleague and asked him to investigate the mobile phone number of Zheng Jun's ex-wife.

Check the short videos hosted by this woman's mobile phone number on WeChat, Douyin, Weibo, and Xiaohongshu.

Lu Shen didn't know what Xu Zheng meant, so he walked over and didn't ask, to see what he was doing.

As Xu Zheng opened the woman's circle of friends and Douyin videos, Lu Shen naturally also saw the content posted by the woman, she used to post content about children, but in recent months, it has been her own.

The content is not to travel everywhere, or to shop and dress up, and people are getting more and more beautiful.

In this case, it is very likely that the woman has started to fall in love, and she subconsciously wants to shield herself from the outside world that she has a daughter, dressed so beautifully, and uses pink lipstick.

This kind of route of pretending to be tender and pure is either to fall in love or to prepare for a blind date.

Lu Shen watched it for a long time, but he didn't see what Xu Zheng was going to do, it stands to reason that Zheng Jun and his wife have divorced, so if a woman wants to fall in love or get married on a blind date, it is her personal freedom.

"Xiao Xu, do you think this woman will help Zheng Jun and Mai Jingwei hide?

Or think that this woman is also their accomplice? ”

Xu Zheng shook his head and denied it, "My thoughts are just the opposite, Brigade Lu, do you think this case looks like an exchange for killing a wife?"

Although the evidence is insufficient now, if you think about it, the bank only sued Zheng Jun alone, indicating that the house that was cut off was Zheng Jun's pre-marital property, and the woman's name was not added.

In addition to the pressure of the mortgage, it is estimated that the man wants to take responsibility for himself, and after the divorce, the bank will not sue the woman.

If the marriage breaks down, then everything is fine.

But if the two divorce and don't leave home, and the woman suddenly doesn't want to live with him, she falls in love with other men.

What do you think he thinks? ”

"Then Zheng Jun will definitely be crazy, after all, he has become an executor after his divorce, doesn't he just want his wife and children not to bear debts.

If his ex-wife is unwilling to live with him, he will definitely not be able to swallow this breath in this situation. ”

According to previous cases of exchanging wives, the two suspects should testify to each other and provide each other with an alibi, or the two pretend not to know each other, or even the two will not have any contact, so as to confuse the police.

But in this case, Mai Jingwei and Zheng Jun both killed Mi Yu's lover, so are they still exchanging wives to kill them?

Xu Zheng shook his head and said: "It seems that this case is not an exchange for killing his wife, Mai Jingwei is a crime of passion, of course, it may also be instigated by Zheng Jun."

As for Zheng Jun, he automatically became Mak Jingwei's accomplice when he hit that stick.

If he uses this to blackmail or ask Mak Jingwei for something, do you think Mak Jingwei will agree to him? ”

"That's for sure!" Lu Shen sighed, "Both of them have committed crimes as a gang, and the grasshoppers with a rope must advance and retreat together." We agreed before that Mak Jingwei had not seen his children for two years abroad.

Then when he comes back this time, why should he meet his son and parents?

As a result, we squatted for four days and didn't see him show up, and now we look at it, it should be Zheng Jun who stopped him. ”

The colleague who inquired according to Xu Zheng's instructions just now reported: "Director Xu, I found out the trajectory of Zheng Jun's ex-wife, Luan Yiyi's actions in the past four days, she either went to supermarkets or scenic spots in Changming.

I haven't been to the Xinhuamen community, nor have I been to Jiangjun Mountain.

Moreover, there is nothing abnormal in the content of her calls and WeChat chats.

Do you want me to call up the surveillance near the community where she now lives, and check if Zheng Jun and Mak Jingwei are here? ”

Xu Zheng patted him on the shoulder, "Of course you have to check, but you tell me now, where is this Luan Yiyi now?" ”

The criminal policeman operated for a while, and quickly locked Luan Yiyi's location through her mobile phone number, "Her mobile phone location shows that she is now in RT-Mart Supermarket on Shangyuan Street."

Do you want to notify the ground patrol police and go over in advance for tracking and protection? ”

"That's not good, the patrol police are wearing police uniforms, in case it is not good to startle the snake, you first check the monitoring of the community near Luan Yiyi, if necessary, you can notify the police station in the jurisdiction to get the community monitoring."

After Xu Zheng finished arranging, he proposed to Lu Shen again: "Brigade Lu, why don't we go and follow this Luan Yiyi, or I go alone, I always feel that people like Zheng Jun dare to bear the punishment of dishonesty after the confession is broken."

Moreover, he was decisive and ruthless, and his anti-reconnaissance awareness and ability were very strong.

There is an element of tyranny in his personality, so he will not let go of a woman who wants to put a hat on him, even if it is his ex-wife. ”

Lu Shen was a little embarrassed, he was now the person in charge of the 12.16 case, and it was the right topic to stay in the conference room to be responsible for the overall work at this time, but now, he felt that Xu Zheng's analysis made sense.

To go or not to go?

He made his own decision, "Xiao Xu, then you will lead the team, should I match you with a female colleague or a male colleague?"

Easy for you to perform tracking tasks?

Also, I will apply to the Yuhuatai Criminal Police Brigade to send someone over to cooperate with your work. ”

Xu Zheng looked around at the colleagues who stayed in the conference room, but unfortunately the only two female colleagues were either older or not talented and beautiful with him, he pouted slightly, "Team Lu, let's follow it alone."

Rest assured, tracking and monitoring, I'm professional. ”

Lu Shen saw Xu Zheng's small action just now, and smiled secretly in his heart, the two female criminal policemen under him, walking with Xu Zheng, will indeed have a high return rate, after all, handsome men and beautiful women are the standard.

"Okay, whatever you arrange, I'll send someone to contact the police station where Luan Yiyi Community is located, and ask them to send someone to the community to extract surveillance video, let's do it at the same time to see if we can find Zheng Jun and Mai Jingwei."

"Just arrange it for the Lu brigade, now I am a soldier under you, and everything is under your command." Xu Zheng was originally a consultant, but now he took the initiative to participate in the case, so he had to put himself in a correct position and not disrupt Lu Shen's arrangement.

Lu Shen laughed and slapped Xu Zheng's arm, "Although I know that your strength is super strong, I still remind you to pay attention to safety." ”
