After investigating the residents and tenants of the entire building, it was found that none of these people were suspected of committing a crime, so it was time to start investigating the players who played mahjong in the mahjong parlor downstairs that night.

There are a lot of people who come to play mahjong that night, but most of the people who play mahjong here at night are regulars, and many of them know each other, so the investigation can also lead to several card friends from a card friend, and basically there will be no omission in the investigation.

The purpose of the investigation team was to extract the DNA data on these items, and then compare the extracted DNA data with the national DNA database to see if anyone with a criminal record could be found.

Lao Lu believes that this crime may have been committed by someone with a criminal record.

I have not denied his inference, because the proportion of people with criminal records who commit crimes again is still relatively high in all cases. Moreover, in the wealthy community, where there is a large flow of people, a small number of permanent residents, and a large number of foreign tenants, the possibility of people with criminal records committing crimes is still very high.

As far as I know, there are more than 300 pieces of physical evidence that can be extracted from DNA collected at the scene, and it is a heavy task to extract and compare so many physical evidence.

However, no matter how heavy the task was, the public security policemen of the technical department still worked hard and completed the DNA comparison in a short time.

After the results of the comparison came out, it was found that there were three people with criminal records.

The first is Shao Daifeng, who once served a prison sentence for robbery, and has now been released for two years.

The second is named Li Shunkong, who once served a sentence for manslaughter and was released just half a year after completing his sentence.

The third is called Qi Shenghuan, who once served a prison sentence for fraud and was released for a year and a half.

Lao Lu summoned the three people.

Shao Daifeng was the first to come to the criminal investigation team, he was not tall, about 170 cm, but he had a strong physique, flat head, thick eyebrows and big eyes, and a Chinese face. To tell you the truth, the first time I saw him, I felt that he had a righteous and awe-inspiring appearance. It's strange how a former robber could have such an aspect. It seems that people are really unseemly.

The summons was only for the suspects to come and cooperate with the investigation, so they were not allowed to enter the interrogation room, but only to be questioned and recorded in the office area outside.

Lao Lu asked in person, and I stood aside to listen.

Lao Lu's police uniform looks very majestic, and he is tall and burly, this posture can make ordinary people, especially suspects with poor psychological quality, tremble immediately.

However, Shao Daifeng was not shocked by Lao Lu's momentum. I could see in his eyes a sense of calm and composure, not in disguise, but in a visceral expression.

From this glance, I thought that this man was not a murderer. Although it is a bit too subjective, I believe that I can accurately grasp the facial characteristics of the characters, unless he is an Academy Award-winning actor. But I believe that actors are not just available on the street.

The two sat facing each other, Lao Lu had a stainless steel water cup with a lid in front of him, and Shao Daifeng had a disposable plastic water cup in front of him, with a little green tea in the cup, and smoke slowly drifted out of the cup.

Lao Lu asked, "What's your name?" ”

Shao Daifeng said calmly: "Shao Daifeng." ”

"How old are you this year?"

"37 years old."

"What profession?"

"Security."

Hearing this answer, Lao Lu picked up the water cup, lifted the lid, and took a sip of water.

I knew he was thinking, thinking about how a man who had been imprisoned for robbery would take up a job as a security guard after he returned to society.

Of course, I'm thinking about this as well. However, I think it is a good thing, which shows that the society is becoming more and more inclusive, so that former prisoners have a wider range of employment opportunities, which is a kind of help and affirmation for those who have reformed their ways.

Perhaps this is why Shao Daifeng has a righteous and awe-inspiring look. Because now as a security guard, he must have completely abandoned his previous self of breaking the law and discipline, and reshaped a person who abides by the law and can stand up to maintain peace and order.

Lao Lu put down the water glass and continued: "Do you know our intention in calling you to the criminal investigation team this time? ”

Shao Daifeng said: "I know." You want to know how the lady of the mahjong parlor died, right? I know you're suspicious of me, I'm a criminal record, and you have a legitimate suspicion of me. Because it's not the first time I've been suspected. But don't worry, I'm a very open-minded person, Ming people don't do dark things, and I'm not afraid of shadows. You will investigate me, and come, and I will cooperate with it. ”

I wanted to laugh a little, because Lao Lu's expression was a little embarrassed now. Because what Shao Daifeng means is to say, you policemen suspect that the wrong person is wrong, but I have a large number of adults, so I don't care about you, and I still cooperate with you in the investigation.

Lao Lu said: "Okay, then tell me, what are you doing from 1 to 2 o'clock in the morning on the night of the crime?" ”

Shao Daifeng said: "I remember this very clearly, I left the mahjong parlor at about half past one in the morning that day, because I had to go to work for two days and couldn't play all night." I have two brothers who came home from working in other places for the Chinese New Year to testify, because all three of us were playing mahjong there at the time, and you can ask both of them if you don't believe me. Oh, by the way, I bought a pack of cigarettes from the owner at the mahjong parlor when I left, and he can also prove that I was in the mahjong parlor at the time. ”

Lao Lu nodded and asked for the contact information of the two witnesses in Shao Daifeng's mouth.

In the subsequent investigation and understanding, the suspicion of Shao Daifeng was indeed ruled out, and a news related to Shao Daifeng was also excavated.

A year ago, a three-year-old girl fell from the third floor, and Shao Daifeng, who happened to pass by downstairs, desperately caught the falling girl with both hands, so that the little girl survived. Although Shao Daifeng's arm was slightly injured, it also won people's respect for him. It is precisely because of this incident that a company in the district hired him as a security guard, and now Shao Daifeng is already the security captain there.

Lee Soon-kong is the second person to come to the criminal investigation team. This person is tall and thin, with heavy dark circles under his eyes, and it seems that he is either weak or has stayed up late for a long time. He was wearing a knee-length black down jacket, which looked very strange. This down jacket is either worn by ladies or fashionable young people. The age of this person is clearly stated in the information, and it can be easily surmised that he is 51 years old this year.

Because this person had killed people, Lao Lu did a detailed study of his information. It turned out that this man had killed an adulterer who had had an affair with his wife. His murderous modus operandi was also shocking, when he caught the adulterer in bed, he ripped off the bedside lamp of the hotel, and used the lamp to attack the adulterer's head, causing his skull to rupture, and he died after resuscitation. It can be seen that his anger at that time has reached the extreme, so he erupted with terrifying power.

Lee Shun Kong has a son who is nineteen years old. However, this son is quite backbone and very competitive, and would rather live with his grandparents than with his cheating mother. And before his father was released from prison, he gave him a big gift and was successfully admitted to Chongqing University.

After reviewing these circumstances, I guess that the fashionable over-the-knee down jacket should be his son's former clothes.

It's still the same table and chair, it's still a water cup and a plastic cup, the plastic cup is still green tea, and the tea is still steaming.

Lao Lu's opening remarks were no longer asking what name, age, and work unit, he directly asked: "What are you doing from 1 to 2 o'clock in the morning on January 10?" ”

Li Shunkong thought for a while and said, "I should be sleeping, officer, I don't remember clearly." ”

Lao Lu thought about it, took a report from the side, opened it and looked at it.

I have also read this report, which is some basic information of Li Shunkong, and of course, the report of this DNA test. The report said that Li Shunkong's DNA data was extracted from a napkin at the scene of the crime, and there were blood stains on the napkin, which should have been left by coughing up blood in the mouth. From this point, it can be proved that Li Shunkong is suffering from a disease.

Lao Lu said: "Have you ever been to the mahjong parlor in the rich community on January 9? ”

Li Shunkong said: "Yes. Recently, I had nothing to do during the day, and I asked a few friends to go to a friend's house in the Fortune Community. Then we went to a mahjong parlor there to play cards, and before dinner, we ate together at a nearby hot pot restaurant. I remember eating the hot pot and we went home. But then I heard that the proprietress of the mahjong parlor was killed, and you called me here for this matter, right? ”

After Li Shunkong finished speaking, I was sure that he would not be a murderer, and if he was really a murderer, he would not appear in front of us at this time.

He couldn't be pretending to be crazy and stupid? Obviously not, the real murderer's first reaction is to run away, and he won't run to play any psychological tactics with the police like in the TV series.

Lao Lu nodded and said, "After you and your friends separated, is there anyone else who can prove that you were not at the scene of the crime at the time of the crime?" ”

Li Shunkong said: "Proof? I live with my parents and only they can prove it. However, they are old and not very good, and I hope this incident will not bother them. Because I already had a criminal record of murder, I was worried that they would know that I was under suspicion again, and that something would go wrong with my body. Comrade policeman, you have to believe me, I really didn't kill anyone, if I did, would I still come to the police station to throw myself into the net? ”

Lao Lu frowned, picked up the teacup and took a sip of tea.

I patted Lao Lu on the shoulder, Lao Lu turned his head to look at me, and I motioned for Lao Lu to come out with me.

Lao Lu got up, we walked outside the door, Lao Lu asked, "What do you want to say?" ”

I said: "This Li Shunkong is not a murderer, so to speak, the possibility of the person who can be summoned is the murderer is relatively small." ”

Lao Lu said: "Your statement is too one-sided, I can't agree with it." What if the murderer was so confident that he wouldn't be caught? ”

I said, "Others will, but this person won't." I have read his information, he used to be a construction boss, and his parents are also middle-level cadres in banks, and his family background is very superior. He will not kill people because of those gold jewelry, and he is not a person from the rich community, and he will not have any grudges with the deceased Tao Cunfang, he has no motive to kill. Moreover, this person has a disease, and his condition is still relatively serious, and in a one-on-one situation, he may not be able to subdue the healthy Tao Cunfang. ”

Lao Lu thought for a while, glanced at me, and walked into the house.

I didn't go into the house, but lit a cigarette outside, and smoked in the cold wind while looking at a big bare tree, thinking in my heart.

It didn't take long for Li Shunkong to come out of the house. When he came out, he wrapped tightly around the long black down jacket with a white skull printed on the back. This kind of fashionable clothes are worn on this person who is over half a hundred years old and sick, showing nondescript.

As soon as Li Shunkong went out, perhaps because of the cold air outside the door, he began to cough, and the coughing voice was very hoarse, obviously because he had been ill for a long time.

I saw him tremble and take out a napkin from the pocket of his down jacket, wipe it on his mouth, cough a few more times, and spit a mouthful of phlegm on the napkin.

He stood there and looked at it for a moment, then turned around and walked back, throwing the napkin into the trash can behind him.

The moment he threw out the napkin, I could see a touch of red on the napkin. It looks like he's coughing up blood again.

In fact, Lao Lu had been suspicious of Li Shunkong, and it was not until the case was finally solved that he dispelled this idea.

Later, we learned that this Li Shunkong died half a year later, and the cause of death was lung cancer.

The third suspect who was summoned was Qi Shenghuan.

The first time I looked at this man, I almost didn't laugh. Because his walking posture is so bizarre that ordinary people can draw a conclusion at a glance, sissy.

I have studied this person's criminal history, specializing in defrauding women, and the method of fraud is to sell some women's products produced by informal manufacturers at high prices, such as diet pills, breast enhancement creams, face slimming injections, etc.

This kind of behavior of his could only be regarded as peddling fake and shoddy products at high prices. But why was he convicted of fraud? Because he organized a gang and used the form of 'trust' and his incorruptible tongue to successfully deceive many rich women into buying millions of counterfeit and shoddy products from him. In the end, these rich women jointly sued the court and convicted of fraud.

However, it can be seen that this Qi Shenghuan's life after being released from prison is still colorful. He wore a white tweed coat, a black fashionable woolen scarf around his neck, and a pair of black shiny leather pants. To be honest, this is the first time I've seen a man wearing such shiny leather pants on the street. The long black leather shoes on his feet, and I felt that this man had been coquettish to the extreme.

He sat in the same place where the two had sat before, but there was no tea in front of him, as he said he only drank coffee. But this is a criminal investigation team, not a café, and no one will come to serve him. So there is no more boiled water.

He was sitting in front of me now, and I could see his face. The black hair with hair oil is combed with a part, the eyebrows are obviously painted, thick and thick, and the skin on the face is oily and shiny, which seems to be usually well maintained. I don't have a beard, not even stubble, I don't know if it's too clean shaved or not grown at all.

"Sir, what's the matter, I'm a good law-abiding citizen now!" This Qi Shenghuan, before Lao Lu opened his mouth to ask him, he first began to defend himself, and he used nondescript Hong Kong-style Mandarin with salt and pepper Mandarin.

Lao Lu said in a deep and serious voice: "Good talk, I know that you are a native of Wanzhou, don't play tricks with me." ”

Qi Sheng shook his head, glanced at his eyes, and the corners of his mouth were deflated, and the expression of a woman made us laugh. I know that this kind of expression is not something that can be pretended casually, it is an expression that emanates from the bones. It's really weird.

Lao Lu didn't care whether it was a human or a demon sitting opposite him now, and asked in a deep voice: "What are you doing from 1 to 2 o'clock in the morning on January 10?" ”

Qi Sheng rubbed the woolen scarf, looked at the ceiling at a 45-degree angle, frowned, and said in a girly voice in the local dialect: "Officer, I'm very busy every day, how can I remember what I was doing at that time?" I thought about it, I should be sleeping in beauty sleep, my skin needs to be well maintained, and now I am over 30 years old, but I am aging fast, and it is not easy to maintain ......"

"Stop, don't say anything useless, you can answer whatever I ask." Lao Lu said sharply.

Qi Shenghuan is the signature strange expression again.

Lao Lu continued to ask, "Do you know the purpose of our summons for calling you here this time?" ”

Qi Sheng looked around at Lao Lu, and then looked up at me who was standing aside, his Adam's apple squirmed up and down, it turned out that he still had an Adam's apple.

He said timidly, "I...... I really don't know, what the hell did I do? ”

His series of performances shows that he knows what he has done, but it is not related to Tao Cunfang's death, only he knows.

But I'm sure that this weird guy must have done something illegal and undisciplined in private.

Lao Lu said: "Have you ever been to the mahjong parlor downstairs of the Fortune Hotel?" ”

Qi Shenghuan said: "I know, the Tao boss of the mahjong parlor is still my customer. ”

Lao Lu asked, "Your customer?" What do you do now? ”

Qi Shenghuan showed a proud expression on his face, and he said sharply: "I am now doing lady shaping, beauty breast enhancement, and spa. As he spoke, he took out a small golden box from his pocket, took out a business card from it and handed it to Lao Lu, and continued: "Comrade policeman, you can also recommend your wife to come to our store for physiotherapy, and I will give you a seven-percent discount." ”

I laughed in my heart, this kid went to the criminal investigation team to engage in sales promotion.

Lao Lu took the business card, glanced at it, and then looked at Qi Shenghuan, and asked quietly: "Recently, Boss Tao went to your store to take care of business?" ”

Qi Sheng frowned and said, "No, I haven't been here for many days." I still have to contact her quickly, I invested 2,000 yuan in her and asked her to help me speculate in stocks, I don't know if I made any money? ”

Lao Lu hurriedly asked, "You gave her 2,000 yuan and asked her to help you speculate in stocks?" ”

Qi Shenghuan said, "Yes." She is a VIP user in my store, and she has been an old user for more than a year, so it can be said that when my store opened, she came to take care of the business. And every time she comes, she wears a very foreign style, and her whole body is covered in gold jewelry, and she looks like a rich woman. I asked her what she used to get rich, and whether it was just that little mahjong parlor. At first, she was reluctant to say, but after a long time, she told me. It turned out that she was a senior stockholder, and she had a very good set of stock speculation. But I don't know how to speculate in stocks, but I also want to make money, so I gave her 2,000 yuan, and I tried the water first to see if I could make money, even if I lost, it wasn't much. Anyway, she promised me that she would definitely make money. But after a few days, she didn't respond to me. She's not going to be a fraudster, is she? ”

This information is very important, and in the past few days of investigation, no information has been obtained about whether the deceased is a shareholder or a shareholder. It seems that Tao Cunfang speculates in stocks, and not many people know about it. Plus this information doesn't seem to have much to do with the death of the deceased, so the insider hasn't revealed it either.

Lao Lu joked: "How can there be so many fraudsters? ”

Of course, Qi Shenghuan could hear the words, so he made that strange expression.

Lao Lu looked through Qi Shenghuan's information and said, "We found the mineral water bottle you drank in the mahjong hall in the rich community, did you go there on January 9?" ”

Qi Shenghuan put his hands on the table, and his ten fingers began to tap each other quickly, and then grabbed the top of his head with his left hand, showing a thinking expression, and finally he said: "By the way, I remembered, I rested that day, so I went to Boss Tao's mahjong parlor to play a few rounds of mahjong." ”

Lao Lu asked: "Is there anyone who proves the specific time of going to the mahjong hall and the specific time of leaving?" ”

Qi Shenghuan said: "How do I know the specific time, I remember that I went after lunch, and I left before dinner." I'm a go-getter, and I didn't ask anyone else, so no one can prove it. Comrade policeman, what happened to you, you asked me like this, as if you were suspecting that I had done something bad? ”

Lao Lu said: "Boss Tao of the mahjong parlor was killed on the night you went to the mahjong parlor, and everyone who has been there is suspicious." ”

Qi Sheng stood up in a circle, his face full of horror, and his mouth screamed: "Oh my god, no! ”

"Sit down!" Lao Lu said sharply.

Qi Shenghuan hurriedly sat down, and reacted quite quickly and said: "Comrade policeman, I am definitely not the murderer of Boss Tao, you have to believe me!" ”

"Then you'll have to give yourself a reason to be present." Lao Lu said.

Qi Shenghuan began to hit each other with ten fingers at a rapid pace, his hands were very white, his fingers were very long, and it could be seen from the speed of the hitting that his fingers were very flexible, it seemed that these hands had a few brushes for beauty.

He suddenly said, "Oh, yes, yes. I went to the store that night to pick up something, it was late at that time, and there was surveillance footage in my store that could prove that I was not at the mahjong parlor that night. ”

Lao Lu nodded, so he sent someone to investigate the SPA hall around Qi Shenghuan.

Sure enough, this SPA hall is at a street intersection about 800 meters away from the Zhifu Community, and from the surveillance video of the SPA hall, Qi Sheng was indeed seen going in and out, and the time he left the SPA hall was one o'clock in the morning on the 10th. From here to the mahjong parlor in the rich community, it is obvious that the killing time will be missed.

And it can be seen from the surveillance screen that Qi Shenghuan walked towards the back of the façade after leaving the SPA hall. According to the field investigation, behind the façade is a stairwell leading to the second floor, because Qi Shenghuan rents a house, which is on the upper floor of his SPA pavilion.

Obviously, Qi Shenghuan also ruled out criminal suspicion.

However, Qi Shenghuan was arrested by the police afterwards for illegally selling illegal drugs in the SPA hall. That's why he behaved so abnormally when asked.
