Back to 1990. Criminal Investigation

Ding Chong: "What are we talking about? Liang Cheng's death has nothing to do with us."

Leng Jiucheng was not in a hurry to speak. He lit a cigarette, took a puff close to his mouth, and slowly exhaled the cigarette. In the wisps of smoke, his eyebrows and eyes were slightly raised, which seemed to be a smile but not a smile. Showed countless contempt and ridicule.

Ding Chong's back felt chilly, as if being entangled by icy vines, and at the same time, a wave of anger was aroused. He could see that Leng Jiucheng not only did not believe what he said, but also despised and hated him very much. He said angrily: "If you don't believe me, go and investigate. What's the point of handcuffing me here? Extorting a confession by torture?"

Leng Jiucheng put out the smoke, and leaned back on the back of the chair with his arm, "The tools in the utility room are messy, and the shoe prints on the ground are messy. According to the shape of the shoe prints, there were at least five people in the utility room at that time. There were footprints on Liang Cheng's body." , there are broken stool legs and a hammer in front of him, which means that he fought with people before his death. After being beaten, his skull was smashed to death with a hammer. Unfortunately, a classmate saw you and walked past that classroom in the evening self-study , if you didn't kill anyone, what did you guys do in the utility room? Play hide-and-seek with Liang Cheng?"

Ding Chong: "My friend beat him, but he didn't kill anyone. We left after teaching him a little lesson. We didn't expect him to die."

Leng Jiucheng's shoulders trembled, and he snorted softly, "Whose owns the hammer?"

"The hammer was used to scare Liang Cheng, and it never touched him."

"Then why is there Liang Cheng's blood on the hammer?" Leng Jiucheng asked back.

Ding Chong was silent for a moment, "I don't know, anyway, what I said is all the truth, if you don't believe me, call Bai Ren and the others to ask."

Leng Jiucheng suddenly moved forward, approaching Ding Chong, pinched his chin again, and said through gritted teeth: "You are ants on a rope, equally ugly, asking them to ask is no different from asking you alone."

Ding Chong smelled the faint smell of tobacco on Leng Jiucheng's fingers, and felt a strange sense of familiarity in vain. He raised his hand and pushed Leng Jiucheng away, and subconsciously touched his chin, "Speak as you speak, don't touch me."

"Disgusting?" Leng Jiucheng stretched out his hand to support the back of Ding Chong's head, and bumped his forehead hard. The moment the pain came, he let go and sat back down again.

Squeezing his chin and bumping his forehead are two of Ding Chong's favorite actions when he is angry. Leng Jiucheng still remembers that expression of arrogance and contempt for everything. At that time, Ding Chong regarded himself as the God who ruled the world, but in Leng Jiucheng's eyes It was the clown without clothes. The corners of his mouth curled down imperceptibly, and his eyes showed deep disgust. He said coldly, "You may fall in love with these two movements in the future."

Ding Chong rubbed his painful forehead, "I like to hit my forehead? Is my brain sick or have iron head skills? Do you have a memory disorder and think of me as someone you knew in the past? Mr. Leng, Officer Leng, please be sober. We've only known each other for a day or two."

Leng Jiucheng said word by word: "Ding Chong, one day you will remember me."

Ding Chong was calm on the surface, but in fact he pulled out the eighteenth generation of Leng Jiucheng's ancestors to greet him again.

Leng Jiucheng looked indifferent, and spoke confidently, "Smash Liang Cheng's head with a hammer, and fingerprints will be left behind. It doesn't matter if you don't admit it. When the fingerprints on the crime tools are extracted, I will ask you to come to the police station to compare them one by one. of."

"If we killed Liang Cheng, you wouldn't find fingerprints at the scene at all. You have left so many traces and clues, and you still have to leave fingerprints on the murder weapon. Isn't it obvious that the police will catch you? It's better to surrender yourself, I Wouldn't do something so stupid."

Hearing the words Leng Jiucheng raised his eyes to meet Ding Chong's. At this moment, he saw the shadow of Ding Chong in 2021. Ding Chong has a high IQ, an arrogant personality, and hates all stupid behaviors. From this perspective, so many people left at the crime scene It's really not like Ding Chong's style.

In order to convince Leng Jiucheng, Ding Chong said: "If I were the murderer, first of all, I would not kill someone at school. The school where the crime happened, and the time for self-study in the evening, these two points are enough for the police to immediately suspect that the murderer was in the school. Because it is inconvenient for people outside the school to enter and leave the school, and it is easy to be recognized, if people outside the school enter during the incident, they will definitely be seen by guards, teachers, and classmates.

In Liang Cheng's case, no one saw social personnel entering the school, so you must first lock the murderer among the students, which undoubtedly increases the risk of exposure for the murderer.

If it were me, the place where the crime happened would be outside the school, and the time of the crime would not be during the class period. I would ask him out during the holidays, take him to some remote areas, kill him and throw them into the river silently. The river water can wash away some fingerprints Or evidence, and the corpse rots quickly in summer, no one finds it in a few days, the corpse will rot to the point where your mother doesn't recognize it, and after you find it, it will take a lot of time to verify your identity.

Or bury it in the soil or in the grave. Take the grave as an example. Generally, no one will move the tomb easily, and they will not visit the cemetery often, especially those old graves with no descendants. When the rain washes away, it is even more difficult for anyone to find that the tomb has been moved, and the corpse is secretly buried in the tomb. You will not find it for ten or twenty years. Even if you find it one day, the corpse will rot into bones. There are many, many methods for one person, why bother to let people die in school with great fanfare, waiting to be caught by you.

Secondly, Liang Cheng hates me, and often has trouble with me. This time the fight was started by Liang Cheng. He openly provoked him many times, but I ignored him. He went to challenge my friends outside the school. Li Jingwei wanted to teach him a lesson and let him live in peace. , Just went to the classroom to fight.

There is no impenetrable wall. Sooner or later you will know about the relationship between me and Liang Cheng. You usually have a bad relationship with the deceased, and you fought with him before you died. You are still a student at school. Based on these points, you must be the first Doubt me, the whole thing is colluding, which is equivalent to digging a hole and jumping on your own. How stupid am I to do such a stupid thing? "

The reason why the case became an unsolved case is inseparable from the social environment at that time. In the era of underdeveloped criminal investigation technology, the police really had no choice but to meet a murderer with a strong sense of anti-reconnaissance, and the public did not have such a high awareness of criminal investigation. Fang Yuanyuan's parents have not reported their child's disappearance for many years. Under such circumstances, the police may not be able to detect Ding Chong's murder method immediately.

The grave, the bones, and no one found it. Leng Jiucheng was shocked for a moment. Fang Yuanyuan's body was dug up in the Leng family's ancestor's grave after a thousand years. Could it be that he killed Fang Yuanyuan like this?

Ding Chong's remarks, if viewed from the perspective of 2021, are not so superb criminal ideas, but 30 years ago, he had such subconsciousness in his youth, which is enough to see that his mind is more mature than his peers, and his reasoning and logical thinking are also higher than those of his peers. ordinary people.

Devil or angel, lunatic or genius, the two extremes are sometimes only for a moment, a terrible thought suddenly popped up in Leng Jiucheng's mind, if Ding Chong was the leader of that gang, and Chen Ling was just a cover, he gasped suddenly Angry, I dare not think about it anymore.

Leng Jiucheng looked at the young man in front of him, and suddenly he didn't hate him so much. To be precise, the rebellious Ding Chong was not the same as the young man in front of him. Now that nothing happened, there is still hope to make amends.

Ding Chong flexed his wrist, seeing Leng Jiucheng got up and wanted to leave, then sat down unwillingly and asked the deepest question in his heart, "Why do you always have trouble with me?"

Leng Jiucheng recovered from the complicated thoughts, "I didn't have trouble with you."

Typical of talking nonsense with eyes open, Ding Chong clenched his fists, gritted his teeth and asked, "Then why do you want to strangle me?"

Leng Jiucheng said casually, "Crash evil."

Ding Chong: "..."

Hit you bastard.

He got up to leave, when he suddenly heard Leng Jiucheng say, "Why does Liang Cheng hate you?"

Ding Chong shrugged, "I don't know, maybe there is no reason, like you hate me."

The door was closed, and the youthful aura came from the room. Ding Chong's words still echoed in Leng Jiucheng's ears. Of course, there was a reason why he didn't like Ding Chong, but Ding Chong didn't know it now. Similarly, Liang Cheng must also hate Ding Chong. There is a reason, this may become the key point to solve the case, the police still know too little about Liang Cheng.

Leng Jiucheng chased after him quickly, Ding Chong was climbing up the fence, Leng Jiucheng went over and put his arms around his waist for someone to hug him, and walked directly into the house, "I'll go back later, I still have a few questions."

Ding Chong put his arm against Leng Jiucheng's chest, and felt his hot body temperature through the thin T-shirt. It was strange to be hugged by a man. He forcibly broke away from Leng Jiucheng's arms, and said in a bad tone, "What else do you want to ask?"

"Tell me about the incident before the incident, and tell me every detail."

Ding Chong sat down at the table, and said to Leng Jiucheng like an old man, "I'm so thirsty that my throat is smoking and I can't speak."

Seeing that he didn't speak, Leng Jiucheng silently turned around and poured a glass of water, put it in front of him, and said sarcastically, "Are you hungry? Do you want to make you a table full of Chinese people?"

Ding Chong: "..."

He took a sip of water and said: "Bai Ren and I went home to eat normally during the evening break. At that time, we didn't know that Liang Cheng asked Li Jingwei for an appointment. Cheng didn't dare to provoke me anymore. After learning what happened, when I rushed to the utility room, Liang Cheng had been beaten by Li Jingwei, Zhang Chengbin, and Chen Ling. He spat and scolded my parents very badly, I kicked him on the leg in a fit of anger, and then dragged Li Jingwei and the others away."

Leng Jiucheng: "Who proposed to have a fight at school?"

"Liang Cheng, he said that he would call Li Jingwei everywhere at school to find his teeth, and let his classmates see the class monitor's friends. He is just a young man, and Li Jingwei was so impulsive. Hearing such words, he immediately agreed to the appointment."

"Whose hammer is it?"

"It's Li Jingwei's. After he dropped out of school, he didn't find a serious job. He usually hangs out with Wang Zhongren and the others on the street. He often fights and fights. The supervisor of knives is with him. We got into a gang fight once. Later, Li Jingwei's father put those knives on him Everything was confiscated, and he had nothing to protect himself, so he bought a hammer because he felt uneasy, and he never hurt anyone with the hammer, but he used it to scare Liang Cheng before."

Leng Jiucheng frowned. There was a loophole in this passage. According to Ding Chong, that hammer was Li Jingwei's only self-defense tool at present. How could such an important thing not be taken away at the scene?
