Yuan Chaoyang was taken to the interrogation room of the criminal police brigade, Ling Xu and Jiang Yue were in charge of the interrogation, Huang Yanchen was in charge of taking notes, Liu Xiaoyong, Han Xiaoyan, Cao Shangru, Peng Zhengang, and others sat in front of the screen in the monitoring center, watching every move in the interrogation room through the monitoring screen.

Looking at the cold handcuffs on his wrists, feeling the cold iron chair under him, and looking at the environment in the interrogation room, Yuan Chaoyang said faintly: "I have been to this interrogation room before, when I was escorting a robber over, at that time, the other party was sitting on this interrogation chair, and I was sitting in your place, I didn't expect that I would sit here today." ”

"I didn't expect to sit here interrogating you." Ling Xu said sincerely.

"How did you find this thing?" Yuan Chaoyang looked at the items in Ling Xu's hand.

Ling Xu looked at the white item in his palm and gently put it on the table: "After helping him with the funeral from Yang Shanyong's house, I checked the physical evidence room, the police dormitory, and the garage in the office, because I knew the contradiction between you and Yang Shanyong at that time, so when I checked it, I deliberately paid attention to the people and things related to you."

This is what I found in the physical evidence room of our police station, I looked at the storage label on it, and found that this is the evidence extracted from the scene when you investigated and dealt with a black workshop that manufactured plastic particles, and the person who extracted the physical evidence was yourself, and Mao Jinfeng, who approved the storage and filing, is also the only piece of physical evidence involved in the case in the physical evidence room that was placed and archived by you.

After finding this kind of particles, I found that it could be used as a material for repairing tires, so I asked someone from the technical department to help with the test, and it turned out that this material was consistent with the residual material traces on the tires at the scene. ”

After Ling Xu finished speaking, Yuan Chaoyang smiled lightly: "Hide the wood in the forest, hide the water in the sea." Tibetan cloth in the clothing store, hidden books in the scripture pavilion. I thought that the more dangerous the place, the safer it is, but I didn't expect that you, the director of the police station, had worked as a mechanic and knew the fault mechanism of the vehicle well. ”

After sighing, Yuan Chaoyang glanced at the white plastic object on the interrogation table, and said to himself: "Polypropylene particles, the main components are zinc oxide, chlorinated hydrocarbons, thiodipropionic acid, and dilaurate.

Colorless, odorless, insulation, tough, soft and brittle, wear-resistant, the disadvantage is that it will immediately solidify and form when encountering a low temperature environment, and it will melt and soften when encountering a high temperature environment.

Polypropylene is the raw material for making glue items, according to the different added materials, different types of gum products can be produced, it is the same as water, water can add saccharin can be turned into beverages, added pigments will become ink or various colors of color materials, polypropylene can also be turned into many plastic products containing different ingredients.

The principle of using polypropylene is very simple, after heating it and softening it, plugging it in the hole of the tire, using the air pump to solidify it into shape, so that it can completely block the hole, and then you can pump air into the tire, because the hole is blocked and fused by polypropylene, and the air pressure in the tire is not too sufficient, so the tire can be installed back to ensure normal driving.

However, this tire cannot run for a long time, because the air pressure in the tire is too low, and the tire becomes hot when it rotates, so when the tire is spinning, the polypropylene in the hole will slowly melt and soften as the tire gradually heats up.

When the polypropylene filled in the hole melts to a critical point, the strong air pressure in the tire will blow the melted and softened polypropylene out of the hole, at this time, the tire will appear rapid air leakage, once the left front tire of the car fails, the steering wheel can not grasp the direction normally, so it will cause a traffic accident, when the tire will burst, I did not expect before. ”

"According to what you said, if Mao Jinfeng didn't drive away the police car at that time, but was driven by Yang Shanyong, then he would have had a traffic accident at most, and he would not have encountered fatal danger.

Hearing Ling Xu's inquiry, Yuan Chaoyang paused, and then he told Ling Xu with a calm expression: "So far, I don't have to hide from you, the purpose of what I did at that time was just to teach Yang Shanyong a lesson, and I didn't mean to kill him at all, if I really wanted to kill him, I would definitely carefully arrange a seamless game, instead of this method full of flaws." ”

"There is no such thing as a seamless modus operandi in this world, unless you don't do it, and that's the only way to leave no trace. But once you do something you shouldn't do, no matter how elaborate you set it up, it will definitely leave a flaw afterwards. After saying this, Ling Xu took a deep breath and said in a deep voice, "Tell me about the process of your crime." ”

After hearing this, Yuan Chaoyang sighed, raised his head and pondered for a moment, and said lightly: "Do you know my ideals? I have dreamed of being a police officer since I was a child, and in my heart, the police are sacred, they can arrest criminals, they can bring justice to criminals, and they can also get justice for those victims.

When I grew up, I knew that the police didn't want to be a police officer, I made a lot of efforts for this dream, but every time I was disappointed, 6 years ago, our police station recruited auxiliary police, I didn't want to sign up, but even if it was only more than 1,000 yuan a month for the auxiliary police, it was not easy to be, my father entrusted a lot of relationships, so he sent me in.

I cherish this opportunity, after becoming an auxiliary policeman, I rushed to clean the house every day, as soon as I had time, I learned to handle cases with those formal policemen, in order to be able to assist those formal police officers to handle cases, I found out all the case files, one by one to watch and study, in order to be able to keep a good record, I insisted on practicing calligraphy every night, I had motion sickness when I was a child, but for work, I learned to drive, test driver's license.

I have paid so much for the police career, but because I am an auxiliary policeman, I either go to the village every day to visit the masses, or go to the community to promote legal knowledge, or I am on duty in the police station, and occasionally I encounter two cases, which are also some small disputes caused by trivial matters.

I was a little disappointed when I looked at this kind of mundane work, but even so, I had no intention of leaving, and I tried to stick to it for the ridiculous dream of my childhood.

When my classmates were earning five or six thousand yuan a month, I was still at the police station to earn more than 1,000 yuan, and for this reason, my girlfriend broke up with me, she said that I had no interest, and the little money I earned was not enough for her to buy new clothes, and said that even if I worked as an auxiliary police officer for the rest of my life, I would not be able to turn positive.

Just when I was in a mess every day, Director Mao was transferred to the police station, Mao was different from the previous director, he did things public and private, dared to act, was not afraid of offending people, and arrested many people with backgrounds when handling cases, as long as the crime was committed, no matter how hard the relationship between that person was, no matter how deep the background was, and no matter how many people helped intercede, Director Mao handled it impartially.

I'm not a sycophant, when I saw Director Mao's style, I suddenly had a feeling of seeing an idol, and it was precisely because of this that when Yang Shanyong went on strike to go home, Director Mao asked people to pry open the door of the household registration room, and other auxiliary police officers didn't dare to do it, only I dared to stand up and carry out the order.

Although I knew that doing so would offend Yang Shanyong, I didn't care at all.

It was precisely because of the matter of prying the door, and Director Mao had no manpower when he first arrived, so Director Mao chose me, he didn't care about my identity as an auxiliary policeman, and let me lead the team to participate in the handling of cases in the jurisdiction like those formal policemen, and at the same time, Director Mao also asked me to be responsible for the management of special industries and the submission of forms in the jurisdiction.

During that time, I felt my value, although I was only an auxiliary policeman, but none of the cases I handled were delayed or shelved, I did not let a victim be wronged, I did not have to deal with some confused cases like Song Yang, and my case completion rate reached 100%.

In the management of the special industry, I did not have a trace of favoritism, because I was responsible for the management, registration and reporting of the special industry, and many owners of baths, bars, and K/T/V/ knew that they were not qualified, and in order to avoid being suspended for rectification, they gave me gifts in private, and asked me to help them hide it when I made the report.

But I didn't promise them, seeing that I refused to show mercy to my subordinates, those people asked my friends, relatives, classmates to intercede, and even some people invited Song Yang out, but I still didn't compromise, afterwards, I asked Director Mao to come forward to coordinate, and united several departments to form a law enforcement team to ban those places.

After the establishment of the law enforcement team, Song Yang and those formal police officers were afraid of offending people, and they were unwilling to come forward to lead the team, in this case, I was not afraid of offending people, I led people to ban those unqualified places, for this reason, my relatives and friends have cut off relations with my family, my family was splashed with feces, I was intercepted when I went home, my mobile phone was called every day to threaten me, and even someone sent me a threatening letter, but I am not afraid, and I don't care.

I thought that I would always cooperate with Director Mao, but I didn't expect that a chance discovery would change this qiē......"
