After so many years of work, Yang Qianfeng has a wealth of experience and experience, he believes that the detection of cases is actually a system engineering, especially difficult and complex cases require the participants to have the same goal, careful cooperation and cooperation, each piece can not have the slightest sloppiness, the work must be careful and careful, encounter clues and keep an eye on it, until the investigation is clear, at the same time, the scene investigation, autopsy, visit investigation, case interrogation, etc. Only by working hard in one place can there be a possibility of solving the case. If each party does its own thing, has no information or has a war-weariness, and gives up on the clues that should be investigated without investigating them to the end, etc., these are all taboos in the investigation work.

Whenever he encounters such a major case, he has set strict work discipline for the combatants, who are responsible for each block and who is responsible for the person, and if there is a problem in any of the end, he will conduct a reverse investigation after solving the case, and unceremoniously investigate the responsibility of the person responsible, and at the same time praise and reward the personnel who have made meritorious contributions to solving the case in a timely manner.

Yang Qianfeng and Zhang Lihua, as the main responsible persons for the investigation and visit, did not dare to be sloppy in their work, of course, as he would not be sloppy, in addition to arranging for them to visit the scope of the investigation at the meeting, they doubled the original scope with Li Jiusheng's house as the center, and visited the house day and night, and really did everyone meet, but after more than a day, no clues were obtained, Yang Qianfeng walked on the uneven bluestone road on South Street and said to Zhang Lihua very unconvinced: We have been running around the center of the crime for more than a day, and there is no gain at all. Hearing Su Laining say that he interrogated for a day, Li Jiusheng didn't even say where the family's dog went, and said that the bicycle was stolen, I didn't expect this Li Jiusheng to be so cunning.

Zhang Lihua glanced at Yang Qianfeng while walking on the bluestone slab and said: This is the key thing, he will definitely not say it easily, and the life he says may be gone. After saying that, she heard that Yang Qianfeng's stomach began to make trouble, she looked at her watch and said: It's really fast, it's about two o'clock in the afternoon, let's go eat something first! When you're hungry, you can't do anything.

Yang Qianfeng touched his stomach and said: It's not to find more people when the residents go home for dinner at noon, now that they are going to work again, let's go get something to eat.

Zhang Lihua smiled and said: Yes! The body is the capital of the revolution.

Yang Qianfeng suddenly slapped his forehead and said: By the way, let's go to the sanitation center.

Zhang Lihua also understood and said: Yes! How can they forget about them when they get busy, maybe they can really find something! Let's go to Director Du.

Saying that they sped up their pace and went to the sanitation center, just when all the sanitation workers were in a meeting, the old and rough Du Director was talking, and Yang Qianfeng, who had fought together during the renovation of the city, immediately walked out, Yang Qianfeng explained the intention, the focus is to know if any workers found a dead black pet dog when cleaning the garbage pool, and whether they found a bicycle that was abandoned. Director Du is a straightforward person, he said: Leave this matter to me. As he spoke, he went back to the conference room and said loudly: Has anyone found a dead black pet dog in the garbage pool, has there been? Do you have?

At this time, an old man in his fifties stood up and said: Director, I found a dead black pet dog in the garbage pond on Yunfeng Road at the mouth of Zhengjia Lane, which was packed in an old pillow case at that time, I am a person who believes in Buddhism, and I can't bear to put the puppy in the garbage dump in the garbage dump, so I wrapped it with that pillow and buried it next to the small tree on the edge of the garbage dump.

Director Du said loudly: Well done, very caring. Then he asked: Who has picked up a bicycle that people don't want? Do you have?

A woman in her forties stood up and said: Three or four days ago, I can't remember the specific day, when I went to work at five o'clock in the morning, I found a half-new weighted bicycle next to the garbage pond at the junction of Xinmin Street and South Street and fell to the ground, and when I lifted the car up, I found that the car was locked, I thought it was put there, but the car was still there the next day, and the car was still there on the third day, I thought maybe people didn't want it, so I pulled the car back home with a board car that pulled garbage, and now the car is still at home and has not moved. I don't know if it's the car the police are looking for.

After listening to this, Director Du said: It's good, it's not good if you don't move! After speaking, he asked the women: Do you know that they are the police?

The woman laughed and said proudly: They don't know me, I know them, they are celebrities in our Sunshine City, of course I know.

Zhang Lihua listened to the words inside outside, and excitedly grabbed Yang Qianfeng's hand and said: There is a door, we are hungry for a long time, or your mind is open, and you suddenly thought of taking this shortcut.

Yang Qianfeng was also very excited when he heard this, looked at her hand and said calmly: It hurts me, if you are not your own man, you don't feel distressed!

Zhang Lihua's face turned red, she let go of her hand and hit him, pouting and pretending to be angry: I'm happy, no!

Yang Qianfeng said to the point: Don't be happy too early, I don't know if there is any trace of physical evidence left on it!

Zhang Lihua said happily: It's better than not finding it, haven't you heard? A pillow also appeared. And the bicycle was pulled back with a cart that pulled garbage, and it was left untouched, and I think something of value could be found on it.

Yang Qianfeng couldn't hold back his excitement when he heard her say this: Let them take us to pick up the pillow and bicycle first, and then make materials for these two people later.

Zhang Lihua made an OK hand with her hand and said: OK. After speaking, her stomach also rumbled, and she and Yang Qianfeng both smiled happily.

Opportunities are for diligent and caring people, they immediately informed the criminal technicians of the news, and together with Zhou Jie and others, they dug up the dead black pet dog and the pillow, after checking that the dog was killed, there were many blood stains on the pillow, whether it was Li Jiusheng's family still needs to be identified by his two sons. Then they went to pick up the bicycle non-stop, and Zhou Jie was excited to find that there were blood stains on it.

After finishing the materials of the sanitation workers who found these two things, it was almost four o'clock in the afternoon, and Yang Qianfeng asked Zhang Lihua: Are you hungry?

Zhang Lihua touched her stomach and said: It seems that she is too hungry, but she is not hungry.

Yang Qianfeng was still immersed in the excitement of finding new evidence, stretched his waist and said: I'm not hungry anymore, let's go get something to eat! Think of it as dinner.

Zhang Lihua said with a smile: After eating, the workers got off work again, and they just went to look for them.

After eating at the Linglong Hotel, Zhang Lihua asked: Where do we start?

Yang Qianfeng thought for a while and said: Let's start from Nanshuiguan! In the evening, all the South Street will be visited, and the rest will be almost the same tomorrow morning.

Zhang Lihua said as she walked: I can't see it tomorrow morning, I will be busy until at least two o'clock in the afternoon.

Yang Qianfeng and Zhang Lihua walked side by side, glanced at her and said: Also, many people go to work, and they can only be found when they come back for dinner at noon, but fortunately, Su Laining has more confidence during the interrogation, so that he will not be unable to interrogate.

Zhang Lihua gave him a thumbs up and said: I really convinced you, otherwise Su Laining may lose confidence.

Yang Qianfeng smiled and said: What do you want to serve me? This is our common credit, and besides, I don't know how Li Jiusheng can cheat on these things alone! Completely break through Li Jiusheng's psychological defense, enough for Su Laining and them to eat a pot.

Zhang Lihua said: If we can't break through Li Jiusheng's psychological defense, then we have no choice, but Su Laining still has a hand in interrogation, if he can't get a confession, maybe no one can take it down.

Yang Qianfeng suddenly thought of the new interrogation room and said: Director Ding of the detention center asked for an interrogation system project at the Public Security Department at the beginning of the year, and I heard that it is very advanced, and it is divided into a special interrogation room and a command room, in which you can see all the situations in the interrogation room, and you can also put it on the TV screen on the interrogator's interrogation table in the interrogation room to guide and help the interrogators in the interrogation.

Zhang Lihua glanced at Yang Qianfeng and said: I went in and took a look at it last time I was arraigned, and it was being debugged at that time, and air conditioners were installed in the interrogation room and command room.

Yang Qianfeng and Zhang Lihua entered South Street, and Yang Qianfeng let Zhang Lihua walk in front and said: More delicate than you!

Zhang Lihua turned her head and glared at Yang Qianfeng and said: Am I coquettish? You male policemen can't do anything you can't do.

Yang Qianfeng took a step back and shook his hand and said with a smile: You are not coquettish, you are not coquettish, you are very manly!

Zhang Lihua grabbed Yang Qianfeng and said: You mean I'm a man's wife, I'm not! As he spoke, he pulled Yang Qianfeng and continued: Walk side by side with me, I will eat you!

Yang Qianfeng suddenly remembered the last time he caught a gamble in Feng Xiaolin's old house, and said as he walked: Do you still remember the gamble in Feng Xiaolin's old house?

Zhang Lihua didn't know how Yang Qianfeng mentioned this matter well, and said: Of course I remember, that bet was beautiful.

Yang Qianfeng smiled evilly and said: There must be a sound when you open that door.

Zhang Lihua suddenly came back to her senses, and said while beating Yang Qianfeng hard with her jade fist: What else to say! You can figure it out.

Yang Qianfeng laughed and said while hiding: There are some things that women just can't do.

Zhang Lihua said while chasing: You still say, you still say......

Just as Zhang Lihua stopped the pursuit, a man shouted: Director Yang, do you still know me?

Yang Qianfeng saw that a man was holding a puppy and was so familiar, but he couldn't remember what it was called and where he had seen it, the man pulled his dog over and reminded Yang Qianfeng that he drank wine and beat his wife.

Yang Qianfeng suddenly remembered and said: Yes, yes, your name is Zhu Jianlin, your wife's name is Wang Zhaodi, and you have a daughter named Julie who studies very well.

Zhu Jianlin said happily: Good memory, good memory. It's been a few years, and you can still remember.

Yang Qianfeng jokingly said: I heard that Julie was admitted to college that year, and you still sent me a meal of wine!

Zhu Jianlin smiled embarrassedly and said: Yes, yes, yes, I will make up for it next time.

Yang Qianfeng smiled and said: Forget it, next time Julie gets married, I'll drink her wedding wine, by the way, she graduated, right?

Zhu Jianlin said with a smile: I graduated last year, studied as a doctor, and worked in the obstetrics and gynecology department of the Chinese Medicine Hospital. After speaking, he pulled Yang Qianfeng and Zhang Lihua and said: Let's go, go to my house and sit for a while.

Yang Qianfeng and Zhang Lihua were going to go to these people's homes, so they just followed him to his house, and when they walked to the door, Yang Qianfeng glanced at the door number and said to Zhang Lihua: The new door plate is ceramic, which is much better than the original wood.

Zhang Lihua smiled and said: That week can keep me busy, it's all your doctrine.

Yang Qianfeng entered the door and said: Now that we have door numbers, in addition to us, the people have more people to find someone.

Zhang Lihua said: Yes, although we have worked hard for a week, this is a good thing. As he spoke, he followed Zhu Jianlin to his door.
