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

Chapter 870 The most important witness

Lan Yuying knew that the moment she brought the police home, the so-called friendship between the couple was gone, and she not only had to hand over evidence of her husband's crimes.

We also need to prepare witnesses to testify against him.

She didn't know what she was feeling at this moment, but looking at Luo Jun's affectionate and tearful eyes, she didn't hesitate at all.

After many years of marriage, she has already confessed her role in this family. The so-called love has never happened at all. Luo Jun just needs a wife who does not whore, gamble or be romantic, has a sufficient sex life, and is usually considerate...

In Lan Yuying's eyes, all Luo Jun did was just fulfilling the obligations of a husband. Facts have proved that he is a qualified husband.

But for Lan Yuying, this is a cage, a tragedy that started when they met.

At this time, the seven-year-old daughter looked timidly at Xu Zheng, then at her father, and finally took Lan Yuying's hand, raised her head and asked, "Mom, you..."

Lan Yuying just gently hugged her daughter's shoulders and looked sideways at Xu Zheng, "Officer Xu, please, let's do business first."

Next, there was no difficulty in getting the ten-year-old wet wipes. Behind the makeup mirror in Lan Yuying's bedroom, there was a half-meter-high safe hidden in a hollow in the wall.

It looked very hidden, but Xu Zheng felt that Luo Jun must have known about it for a long time. If he had been alert enough, he would have guessed that Lan Yuying wanted to keep evidence against him at home.

The most likely thing is this safe.

Maybe the wet wipes had been kept in the safe and had long since turned into a dry piece of paper, with dark brown blood stains as big as fingernails obvious on them.

Xu Zheng put the wet wipes into the evidence bag, and suddenly had a strange idea in his mind. He looked at the wet wipes carefully through the evidence bag, but he couldn't see any difference with the naked eye.

"Ms. Lan, are you sure this wet wipe is yours and is the one you kept ten years ago?"

Lan Yuying looked at Xu Zheng strangely, then took a closer look at the wipes, "That's right, you saw it just now. It's been in that cosmetic bag. I haven't touched it in ten years."

"That's okay, I'm just asking casually." Xu Zheng felt that he might have been overthinking it. The most important thing now was to rush back to the city bureau and let the people in the laboratory department work overtime.

See if you can extract DNA from this wipe.

As long as the DNA belongs to the deceased Zhao Meijuan, coupled with Lan Yuying's accusation, and proof of the time when the wipes and blood dried up, it can be used as one of the substantive evidences.

Of course, this evidence alone is not enough to completely identify Luo Jun as the murderer.

More witnesses, as well as physical evidence, are needed.

When leaving, Lan Yuying took her daughter away on the pretext of a friend's gathering. She knew that her fate with Luo Jun was over, even though the house was a private real estate property that his parents bought for her before marriage.

But she turned and left without stopping.

Fan Yu rushed to the city bureau and asked someone to take Lan Yuying and her daughter to a nearby hotel for shelter. She herself rushed to the laboratory department with her evidence bag.

Xu Zheng and others returned to the archives room where Mr. Yan was. Pei Tianshi told the story. Mr. Yan asked strangely: "So smooth? It's a bit unlike Luo Jun's style."

"Do you always feel this way?" Xu Zheng put down the water glass he had just taken a sip from and his expression became serious. When he was at Lan Yuying's house, he felt that everything was going too smoothly.

When Mr. Yan mentioned it again, a thought came to his mind, "Is there something wrong with that wet wipe?"

Yan Lao's white eyebrows were bunched up, "Based on Luo Jun's past work experience and the cases he has handled, he attaches great importance to details. Lan Yuying has not grasped evidence of his violation of law and discipline for so many years.

This shows that he is very cautious, or that he really did not violate discipline.

If you think about such a careful person, he would definitely find the safe hidden by Lan Yuying behind the makeup mirror.

Then after he found out, he saw his wife putting a cosmetic bag alone in the safe, with a bloody wipe inside. In this case."

Facts have proved that Mr. Yan's guess was correct. The laboratory department soon had the answer. The blood stains on the wet wipes provided by Lan Yuying did not contain the DNA of the deceased Du Meijuan.

But it belongs to Luo Jun.

Pei Tianshi was amazed, "No wonder Luo Jun wasn't nervous at all just now. I thought his city was deep, but it was deeper than I thought."

At this time, Xu Zheng recalled his calm demeanor when he met Luo Jun, and his tone when talking to him, which seemed to be an invisible ridicule.

It's a pity that I didn't feel it at that time.

Zhu Qing was a little discouraged. He finally found a piece of substantive evidence, but he didn't expect someone to be more skilled. "Mr. Yan, team leader, what should we do next?"
Can more clues be found on Lan Yuying?
It is estimated that this woman is now happy to overthrow her husband, recover the inheritance left to her by her parents after the divorce, and then immigrate abroad to join her mother. "

Xu Zheng held his chin in his hands and stared at the computer desktop in a daze. Lan Yuying should have no evidence, so all the suspects involved in Du Meijuan's death case.

Luo Jun and Luo Shikai are in public official positions and cannot go to investigate openly for the time being.

So the only way to start is from Sun Chuanbin and Liu Bin. As the saying goes, to untie the bell, you must tie the bell. How did Du Meijuan know them?
Didn't he meet Sun Chuanbin first? After the two had sex, they got together with Liu Bin and others.

"Mr. Yan, I think we should try Sun Chuanbin and Liu Bin again. Although the former had teachers and roommates testifying that he had not left school at the time of the crime.

But he could definitely guess that Du Meijuan's death was related to Luo Shikai and others.

As for Liu Bin, the police did not investigate him back then, and now it is very difficult to find out where his crime scene was.

But Lan Yuying can testify that the two of them once had sexual relations with Luo Shikai and Du Meijuan. "

Mr. Yan heard the helplessness in Xu Zheng's words, and he also understood in his heart that the main reason was that the time span was too long. Even if many witnesses could come forward to testify, after all, ten years had passed.

Even if some people remember it, they must have forgotten some details. Under the attack of the other party's lawyer, these details will often become riddled with holes and cannot be accepted by the court.

"If you only interrogate Liu Bin or Sun Chuanbin based on the relationship between the three of them and Du Meijuan, I don't think the hope is very high."

Xu Zheng now had various details of the case in his mind. He walked to the desk in the office and looked at the standard relationships between various characters on it.

He took out his oil pen and drew another line on Sun Chuanbin's character, and wrote a name, Shi Liqiong.

"Mr. Yan, everyone, perhaps we have all forgotten a key figure, and that is Sun Chuanbin's mother Shi Liqiong.

The time of death of forensic doctor Du Meijuan should be around one o'clock in the morning.

Du Meijuan's roommate Chang Lele discovered and called the police after three o'clock in the morning.

Lan Yuying said that Luo Jun left home probably after ten o'clock in the evening.

According to the time inference, Luo Jun should have gone to the funeral parlor to steal the body first. He had to avoid cameras while going back and forth, stealing the body and climbing over the community.

It's possible in two hours.

After all this back and forth, there is no elevator in Tianlu Community. Shi Liqiong lives below Du Meijuan, so maybe it’s not that she didn’t hear any sound.

I think we can visit her at home. I always feel that ten years have passed and their family has not moved out of Tianlu Community.

Not just because of lack of money. "It's considered good if ordinary people can afford a house in their lifetime. Although Tianlu Community is old, it is in a school district and the housing prices are not low.

When the murder first occurred, the Sun family's house was not easy to sell, but in a year or two, who would care about it. Besides, Sun Chuanbin and his sister have already gone to college.

Are they planning to let their grandchildren go to school here if they don’t move?

Xu Zheng, Fan Yu and Zhu Qing drove here. They had contacted Shi Liqiong before coming and knew she was at home.

And told her about her son being temporarily kept in the city bureau to cooperate with the police investigation.

Shi Liqiong is only 52 years old this year. After meeting Xu Zheng and others, the look of panic on her face became more and more obvious.

She was not alone at home. Her husband and her daughter were also there at this time. Xu Zheng protected his identity after entering the house and observed the three of them.

Shi Liqiong stopped talking, her eyes filled with fear and nervousness, but what really made Xu Zheng suspicious was her daughter, Sun Chuanbin's sister, Sun Qian, a woman about 24 years old.

She actually trembled slightly.

This was because he was so scared that he couldn't control the shaking of his muscles. Xu Zheng felt that it shouldn't be done. At the age of 24, he had already graduated from college.

If you haven't gone to graduate school, you should already be working.

Xu Zheng still remembered that the information showed that Sun Qian seemed to have gone to work and was still a primary school teacher. They were both teachers. How could she still tremble when seeing the police?

As a man, Shi Liqiong's husband took the lead and asked: "Comrade police, what crime has my son committed, and why is he connected to the case that happened ten years ago?"

Xu Zheng found that Shi Liqiong's husband was the only man in their family who behaved normally. Although he was a little nervous, he was more concerned about his son's urgency.

"You should all know about the murder of a woman upstairs ten years ago. Now our police have reopened the case, and someone has accused your son of having an intimate relationship with the victim.

Well, that's the kind of relationship between a man and a woman. "

"This... how is this possible! My son is a graduate student at Renmin University, how could he have a relationship with that kind of woman?" Shi Liqiong's husband was angry and helpless.

He pointed at Shi Liqiong and shouted: "You are used to it, so I will say that woman is not serious, and sooner or later she will pester our son.

I told you how many times I would move, but you just didn’t listen! "

Shi Liqiong was not a good person. She immediately took advantage of a middle-aged woman and shouted at the top of her lungs: "Sun Jinli, are you a man? Whenever something goes wrong, blame me. Your son was admitted to the National People's Congress and you said you have good genes. Now you still have good genes." You have the nerve to blame me."

"What are you shouting for? If you call me again, I'll invite you to go to the police station together." Xu Zheng's face turned cold, and he instantly calmed the couple. He found that these two people were quite interesting. They seemed to be quarreling and shirk responsibility.

But after they had such a quarrel, their emotions were vented, and Shi Liqiong, mother and daughter, visibly calmed down.

Xu Zheng originally thought that asking alone might yield unexpected results, but he felt that doing so too suddenly would make them more cautious, so he had no choice but to drop a bomb.

"Sun Chuanbin may not have participated in the murder of Du Meijuan, but he must know who the murderer is, after all, there is someone who can testify.

He, Liu Bin, and Luo Shikai slept with Du Meijuan at the same time.

If he insists on not cooperating with the police, then the crime of concealment will be inevitable. This is criminal responsibility, no matter how many years in prison he is sentenced to.

In his lifetime, and for the next three generations, he has no way to join the military and take the civil service examination.

So, he is a graduate student at Renmin University..."

"This, this, this..." Sun Jinli's body weakened. As a man, he couldn't hold on for the first time. Perhaps his son who was admitted to the National People's University as a graduate student was his greatest pride in his life.

When he heard about the crime of covering up, he was so excited that he couldn't say anything.

Shi Liqiong was similar. As an ordinary person, she was born to be afraid of going to jail. When she heard that her son's future was gone, her first reaction was to look at her daughter Sun Qian.

As for Sun Qian, she was a little confused to begin with. After seeing her mother's eyes, she became even more panicked.

Xu Zheng watched the mother and daughter's performance from the sidelines, and became more aware that they were indeed hiding something.

When the police conducted an investigation, Shi Liqiong was the top priority because she lived downstairs. As an adult, if she heard anything, she could help the police solve the case.

But she always insisted that she was sleeping soundly and didn't hear anything.

Sun Qian was 14 years old at the time. The police were not very strict with her investigation and only made two transcripts for her. The content was very simple and similar to what her mother said.

"Comrade police, is it because my son Sun Chuanbin didn't cooperate with you? If he cooperated, would he have made a meritorious service? Then what? Didn't you say that surrendering can reduce the sentence? Is there any leniency for confessing?"

Sun Jinli was a little confused and begged Xu Zheng to let him go to the police station to persuade his son.

But Xu Zheng shook his head and looked at Shi Liqiong, "Actually, our police now have a lot of evidence and have basically locked in the suspect.

Now your son, Liu Bin and their classmates have all been summoned to the police station.

But Luo Shikai didn't, and neither did his father Luo Jun, because they are both public officials! "

Xu Zheng's last words were sarcastic, and he wanted to give Shi Liqiong and her daughter the illusion that they would only bully ordinary people when handling cases and would not arrest Luo Shikai, who was also a policeman.

Shi Liqiong's face instantly turned pale, her lips were trembling and she could not speak. She was worried that the police would use her son as a scapegoat and make the case unjust and false.

"Why don't you arrest Luo Jun? Why don't you arrest Luo Shikai? They are the murderers!"

Xu Zheng turned around and looked at Sun Qian, who was yelling at him. This woman's finger was about to point to his nose.

"Obviously the father and son and Liu Bin are the murderers, what does what they do have to do with my brother?

Why did you wrongly accuse my brother?
I want to sue you..."

"Sissi, what are you talking about?"

At the critical moment, Sun Jinli interrupted Sun Qian with a loud roar. He looked at his daughter and then at his wife. With many years of life experience, he immediately realized that the mother and daughter must be hiding something from him.

Xu Zheng did not blame Sun Jinli for interrupting Sun Qian, he struck while the iron was hot, "As long as Sun Chuanbin cooperates with us, you just need to cooperate with us to arrest the real criminal suspect.

I can tell you responsibly that helping us is helping yourself.

Help Sun Chuanbin. "

Xu Zheng was still worried that they didn't trust him, so he quickly asked Fan Yu to come forward and tell their family in detail the importance of the Municipal Bureau's Serious Case Brigade.

"Sissi, tell them." Shi Liqiong sighed, looked at her daughter, and encouraged: "Tell the police exactly what you saw that day."
