Back to 1990. Criminal Investigation

Ding Chong glanced at the handprint on the paper, and raised his eyes to meet Leng Jiucheng's gaze, "What I told you that day was the truth of that day, and I didn't lie."

Leng Jiucheng tapped the fingerprints on the paper, "The fingerprints were extracted from the murder weapon that killed Liang Cheng. The hammer head has Liang Cheng's blood, the hammer handle has fingerprints of Li Jingwei, Zhang Chengbin and you, the size of the indoor shoe prints and The pattern coincides with the five of you. Yesterday, the trace inspection department conducted a second inspection of the crime scene. The results of the two inspections were consistent. The window was not damaged, and there were no valid fingerprints or shoe prints of other people by the window. This classroom, except for the five of you, no one else has ever entered it. The evidence is solid, are you still quibbling?"

Ding Chong said word by word: "I, no, yes, lied to you."

Leng Jiucheng leaned back, put his hands on the back of the chair, "The other day you said that you left the utility room before your self-study last night, and there was no class at that time. Even if he goes in with gloves and shoe covers, there will be scratches on the window. Now there are no scratches on the front and rear windows, and there is no trace of opening to the north. The class near the utility room, we asked the students and teachers, no one heard the miscellaneous that night. There is no sound from the object."

Leng Jiucheng got up and approached Ding Chong, "There can't be a skylight on the second floor. There are no signs of the doors and windows being opened. There are no shoe prints or fingerprints in the rest of the room. Liang Cheng didn't make a sound before he died. Could it be that a ghost went in and killed him?"

Ding Chong rubbed the center of his brows, and there was a wave of ups and downs. The goodwill he had built up for Leng Jiucheng last night disappeared under this strong attack, but it was not Leng Jiucheng's fault. The police investigated the case Talking about the evidence, all the evidence now shows that Liang Cheng's death is related to them. What's going on, Ding Chong can't figure out the reason, so he can only tell the truth: "When I went in, Li Jingwei was threatening Liang Cheng with a hammer. I was afraid of the hammer. When Liang Cheng was hit, he grabbed it and threw it on the ground. Liang Cheng was alive at the time, and there was no blood on the hammer. That's how it happened. I told the truth from the beginning to the end, and I didn't lie to you a single word."

Liang Cheng was fatally wounded on the top of his head. He smashed his head with a hammer and killed Liang Cheng. There is no doubt about it. It is 100% certain that the hammer was the murder weapon. The fingerprints on the murder weapon came from Ding Chong, Li Jingwei, and Zhang Chengbin.

Leng Jiucheng retreated to his seat, recalling his contact with Ding Chong in the past few days. He believed Ding Chong's words for a moment, but he was quickly overthrown because it was illogical. The door has been moved, and no witnesses have seen someone go in. Could it be that Liang Cheng committed suicide?Liang Cheng's fingerprints would be left on the suicide weapon, but now that there are no Liang Cheng's fingerprints on the murder weapon, Ding Chong's words can't stand at all.

Leng Jiucheng stared at Ding Chong, as if he wanted to look into the depths of Ding Chong's soul through his eyes, but Ding Chong's eyes were only honest.

Li Xun rushed in in a panic, "Captain!"

Leng Jiucheng got up and went out, closed the door and asked, "What's wrong?"

Li Xun pointed to the room where Li Jingwei was detained and said, "That Li Jingwei didn't admit to murdering people, but he even attacked our people."

Leng Jiucheng said in a deep voice: "First handcuff him and force him to calm down. Now that the evidence is solid, we have all the time to spend with them."

Li Xun ran away, Gao Qingwu and several other colleagues who were in charge of the interrogation rushed to report the situation, the five unanimously denied the killing of Liang Cheng, and the confession was basically the same as what Ding Chong said.

Gao Qingwu: "The evidence is in front of you and you still refuse to admit it, captain, what should we do?"

Leng Jiucheng: "When I first came in, the confession must be uniform. After a long time, some people will not be able to hold back. As long as they do it, they will definitely show their flaws."

The crowd dispersed, and Leng Jiucheng walked out of the police station. The strong sunlight blinded him. He raised his hand to cover the light, and strode towards a shady place to smoke. If the murderer wasn't Ding Chong, who would they be?Why do you want to do this?How did you kill him?

The murderer did this to frame Ding Chong and others?

Could it be Fang Yuanyuan?

Fang Yuanyuan likes Ding Chong. In order to protect Ding Chong, she deliberately hides the conflict between Ding Chong and Liang Cheng. From this perspective, it is impossible for her to frame Ding Chong, and there is no her shoe print in the utility room. kill.

Liang Guoxiang killed Liang Cheng in order to blackmail the school for compensation?The motive for the murder was established, but how could he enter the classroom and kill someone without leaving a trace?

After Leng Jiucheng thought about it, Ding Chong and the others were the most suspicious, not to mention that they had conflicts with Liang Cheng, but that Leng Jiucheng's attitude towards Ding Chong was not good these days, so they smashed glass and set snakes to retaliate, although their behavior was childish , but it can be seen that these people must take revenge, not to mention that Liang Cheng has troubled Ding Chong since the first year of high school.

The question goes back to the original point, why does Liang Cheng hate Ding Chong?Because Liang Cheng is withdrawn and introverted, he doesn't talk to his classmates, no one knows why he hates Ding Chong.

Leng Jiucheng ran into Li Xun, "Captain, Ding Chong wants to see you."

Leng Jiucheng nodded in response, and walked into Ding Chong's room again. Once the door was closed, they sat face to face. There were only the two of them in the quiet room. "What do you want to say? Thinking of a new lie so quickly?"

"Brother Leng!" Ding Chong showed all his sincerity and respect, "Please believe me once, my mother will be worried if I don't come home for lunch later."

"Don't worry, I'll go back at noon and explain to Aunt Zhang, and we will all go to say hello to your friends' homes."

Ding Chong seemed to be stung by something, and said in a pleading tone: "Can you not tell my mother? He was beaten by my father last night, and today I have another accident. She will go crazy, since we are neighbors." For sake, don't tell her."

Leng Jiucheng raised his eyes and looked at the red envelope on Ding Chong's forehead, thinking of Zhang Juan's steaming bowl of wontons, he was shaken for a moment, seeing the comparison of fingerprints on the table, his personal feelings disappeared again, he would not Letting off criminals due to personal emotions is like being with Chen Ling and the others. No matter how much temptation, touch, or pain he suffered, he never thought of abandoning his faith. There is only justice in his world, and he will never show mercy to those who violate justice, even if Even if he sacrifices himself, he will not let the other party go. This is the fundamental reason why he hated Ding Chong in the past.

In 1990, he was still so cold, it was impossible to let Ding Chong go home because Zhang Juan was sad.

Leng Jiucheng's eyes were like stabbing a knife into Ding Chong's heart, and the begging eyes disappeared in an instant. He stood up and shouted angrily, "I didn't kill anyone, why don't you believe me? Give me a reason to kill someone?"

Leng Jiucheng calmly tapped the fingerprint comparison result on the desktop, "The evidence is here, it's not a question of whether I believe it or not."

Ding Chong laughed wearily: "Since the evidence is clear that I killed Liang Cheng, tell me, what is the motive for the killing?" He looked at the narrow window with iron bars and murmured: "I want to test Department of Chemistry, Tsinghua University, honor my mother, earn money and take her away from Ding Jianmin, to live a good life outside." The tone became more serious: "Why did you kill people? How can you kill someone if you don't do these things?"

At this time, Ding Chong's plan for the future was to study chemistry at university. He was admitted to university, but why did he give up chemistry and go to the police academy?Is it really like in "Infernal Affairs", Chen Ling and the others planned a long time ago to send someone to the police station as an undercover agent. It is precisely because of this that after Chen Ling was arrested, she confessed all the crimes, because she knew that Ding Chong would help her escape .

"What is my motive for killing? Tell me!" Ding Chong pulled Leng Jiucheng back from his wandering thoughts.

"Because Liang Cheng hates you and often has trouble with you, and you guys must retaliate, it is impossible to watch him behaving in front of you and just sit idly by. I have only been unfriendly to you a few times, and you put snakes on the glass. If you don't deal with him for a year or two, how can you let him go so easily?"

Ding Chong looked back at Leng Jiucheng with mocking eyes, "Officer Leng, you targeted me out of nowhere. What's wrong with me trying to teach you a little lesson? I really want to take revenge on you. I will not scare myself like that, Liang Cheng is the same, he often puts glue on my desk, steals homework, and writes threatening letters. If I had the motive to kill because he hates me, I would have done it long ago. ?”

Leng Jiucheng was silent.

Ding Chong said again: "Give me a few days, and I will find evidence to prove that I did not lie or kill anyone."

Leng Jiucheng still didn't speak.

Ding Chong couldn't see what he was thinking, so he could only try his best to prove himself, "This case is very strange, I don't know why the people behind it framed me, but Liang Cheng is a very closed person, if he wants to find the murderer, he must first enter his The world, look for clues from his world, if you look at him with the eyes of an outsider, it is difficult to find a breakthrough from him, if you don’t want to investigate, it’s okay, give me a few days and I will find the murderer.”

Leng Jiucheng finally spoke, "Investigating cases is our duty."

Ding Chong has already developed immunity to his indifferent attitude, "Then let me out, how much better than a murderer who is harmed by an unjust case and a wrong case for a lifetime?"

Leng Jiucheng stared, and sat up straight, "Wrong case? Unjust case? Ding Chong, I admit that I don't like you, but I will never use this kind of thing to deal with you in the name of public welfare. Now the evidence points to you, not me."

Ding Chong knew what he said, which stabbed the stern and selfless police officer Leng, and immediately softened his tone, "Brother Leng, I feel that Liang Cheng hates that I have something to do with Fang Yuanyuan."

Ding Chong's tone softened, and Leng Jiucheng restrained his aggressive temperament, "Why?"

"Sometimes when Fang Yuanyuan talks to me, Liang Cheng will turn his head and stare at me... It's not easy to say, just a kind of intuition." Ding Chong took the opportunity to test: "How about I talk to Fang Yuanyuan?"

Mentioning Fang Yuanyuan, Leng Jiucheng was very nervous, because Chen Ling once said that Ding Chong killed Fang Yuanyuan, and Fang Yuanyuan was indeed dead. The body was in the Leng family's ancestral grave, and the method of burying the body was the same as that of Ding Chong. The reason is that she betrayed her beliefs. The death of Fang Yuanyuan is absolutely true. Fang Yuanyuan is also a key figure in the Liang Cheng case. Is there any connection?

Locking Ding Chong and others in the police station may prevent Fang Yuanyuan from being murdered, but if someone really sets up a trap to frame Ding Chong and the others, the police happen to be in the trap of the real murderer, and wronging someone will bring irreversible harm to Ding Chong and the others. It would really ruin their lives. Although Leng Jiucheng didn't believe Ding Chong's words, he didn't want to wrong him. It would be a good idea to let him out first.

Leng Jiucheng went out and whispered something in Li Xun's ear.

Li Xun opened his mouth into an O, "Captain, the evidence is there, what should we do if we let them go?"

"Send someone to watch the five of them in shifts 24 hours a day. As long as the people on duty don't get lazy, they won't be able to escape."

Li Xun didn't know what Ding Chong said to Leng Jiucheng, and he couldn't understand Leng Jiucheng's behavior, "Captain, can there be false evidence?"

Leng Jiucheng: "The murderer also knows that the police pay attention to evidence in handling cases, and sometimes they will use this to deceive us. If the investigation is too urgent, or the utilitarianism is too strong, they will be confused.

Letting Ding Chong and the others go out temporarily will not cause us any loss. If Ding Chong and the others are the real culprits, they will gather together to discuss the next step in the next few days. Those who are impatient like Li Jingwei may want to escape. If there is an action, arrest them immediately, and then make them speechless.

If they are not the real murderer, the murderer must have spent so much effort to frame them, he must be paying close attention to the case now, the evidence is obvious, but the police let them go, the murderer will be confused, planning such a big game of chess, he can't let him go easily, the police did not If he does not move, he will be restless, and thus continue to commit crimes or show his feet.

For the time being, let's wait and see what happens, and we will take action immediately if there is any action. "
