Chapter 34: The Viper Murder Case (13) There are still many doubts...
[When I have the chance, I will definitely kill her. I have thought of several ways——]
[1. Light coal in the house, then deliberately extinguish the fire to produce carbon monoxide, wait for the carbon monoxide to slowly drift over, and let them die in their sleep. I just need to hide away that night.]
[Second, find a poisonous snake and put it in her bedroom. When the snake bites her to death, others will think it was an accident and will not blame me.]
…
[Sixth, killing people with your own hands. This is the lowest method. Do not use this method unless it is absolutely necessary. If the previous methods have failed, I will consider this one. I will do it at night. After killing the person, I will bury the body and the murder weapon in the farmland to the east. There is a new grave there, and the soil on top has just been buried. The police should not be able to see anything unusual. Even if they suspect something, they cannot dig up someone else's grave.]
The paper was densely written on, and the handwriting was very neat, exactly the same as the handwriting on the small note. Sang Luo could see that it was indeed Zheng Longmen's handwriting, even the strength of the punctuation marks was the same.
Both the master and the disciple were amazed at the piece of paper. They never expected that Zheng Longmen hated He Taohua and her daughter so much that he even made such a long plan to kill them. It seemed that he was not just complaining, but had already hated He Taohua and her daughter in his heart.
Sang Luo could understand it. After all, she was from the modern era and had read a lot of news. Cases like this where neighbors killed each other over noise were not uncommon. Noise could sometimes make people lose their minds, especially in a house with poor sound insulation.
Sang Luo took out the evidence bag, carefully put away the paper, and asked Zheng Wutong: "When did you find this paper?"
Zheng Wutong thought for a moment and said, "It was probably on the night of the crime. On the afternoon of the 31st, Nie Yu returned home and found his wife and child dead. He reported the case to the police, who took the bodies away. Nie Yu also went to sleep somewhere else that night. Considering that my son always complained about the crying next door, I realized that this might be related to my son."
"So my wife and I hurriedly checked his bedroom and searched every corner. We found the hole leading to the next door and also found this piece of paper. Now I am more certain that my son did it."
Sang Luo suddenly became suspicious: "Since you wanted to protect your son, you should have burned this piece of paper right away. Why did you keep it until now?"
Zheng Wutong pursed his lips, "Officer, humans are not machines, how can we be so rational? I was panicking at the time, and I stuffed the paper into my pocket at random, thinking about where to find cement to fill the hole. It was the middle of the night, and all the shops were closed. I asked every store along the street, and finally found a building materials store with someone inside. Then I got the cement and hurried home, filled the hole, and forgot about the paper. It was only when you mentioned it just now that I remembered this thing!"
Sang Luo thought about it and felt that this made sense. She analyzed, "According to this piece of paper, Zheng Longmen had always planned to kill He Taohua and her daughter, but he didn't do it for some reason. On the night of the 30th, he saw Qin Xing's invitation, which stimulated his spirit and caused him to have a mental illness. The anger that he suppressed on a daily basis was released all at once, and that's why he carried out this crime, right?"
Zheng Wutong nodded: "Yes, officer, it's just what you said. On the night of the 31st, we hurriedly patched up the hole, and then lay in bed in fear. No one dared to sleep. Suddenly, I heard my son talking to himself in his room. He said-"
"That's great! That damn kid finally stopped crying. I can finally have some peace and quiet. Hahahaha, that damn kid died well, died well!"
Sang Luo and Ma Shi Tu looked at each other, and it seemed that this was the truth of the case.
A mentally ill patient who was driven crazy by repeating a grade, under the combined pressure of noise and his parents, eventually committed murder.
"But..." Sang Luo was still a little puzzled, "Can a schizophrenic patient commit a crime so meticulously after a mental breakdown? He knew to wear a hood when robbing, and he also knew to threaten others with a gun. This doesn't seem like..."
"There's nothing I can do. My son is not an ordinary patient. He has a high IQ," Zheng Wutong said helplessly.
"One last question," Sang Luo turned his gaze to the small pieces of paper on the table, "Did you know about your son and Qin Xing's affair?"
Zheng Wutong waved his hands repeatedly: "I don't know. I would never have thought of this. You said he should be studying at this stage, how can he fall in love? And even if he wanted to fall in love, why did he have to find that girl from Gu Yixiang's family? Tell me, isn't this deliberately poking my lungs?"
"Anyway, they kept it a secret, not a word leaked out until my son saw the wedding invitation and went crazy that night. That's when I learned about their affair. I was really shocked, but my son was crazy at the time, so we didn't care about it."
"Do you know why the two of them became like this?" Sang Luo asked.
Zheng Wutong clapped his hands and said, "It's all because they didn't listen. This is called bad fate, bad fate! The whole world knows that Gu Yixiang and I don't get along, but my son insists on dating her daughter. Tell me, will this end well?"
"Their relationship has become what it is now, all because of you—" Sang Luo stared at Zheng Wutong with burning eyes, "Your son is mentally ill, and it's also because of you!"
"Because of your stupid and ridiculous face, and because of the boring comparisons between your colleagues, your son's youth has been delayed. He can't go to school and can only sit in a small dark room day after day. If this continues, even the most tenacious person will be tortured to madness!"
"If it weren't for you, Zheng Longmen could have gone to college with Qin Xing. Although they were not in the same school, they could still keep in touch. Although Zheng Longmen didn't get into Jingcheng University, he could still have a wonderful life. It was you who ruined his life!"
Even at this point, Zheng Wutong still refused to admit his fault. He said stubbornly, "What have I done wrong? As parents, we are doing this for his own good, so that he can have a bright future! Who told him not to live up to expectations? He always missed the admission to Beijing University by a few points. If he had listened to me and tried harder before the exam..."
Sang Luo was too lazy to listen to him. He walked out of the interrogation room irritably, opened the window and lit a cigarette. Ma Shi Tu also finished the interrogation soon, came out of the interrogation room and walked to Sang Luo.
"Do you feel a little stressed? It's normal. This is how it is in our line of work. You will meet all kinds of people." Ma Shi Tu comforted.
"How are they?" Sang Luo was referring to Zheng Wutong and his wife.
Ma Shi Tu sighed: "Even after being criticized and educated by me, he still doesn't think he is wrong. Tsk tsk tsk, a person like this can actually be a teacher. He is really misleading his students!"
Sang Luo also sighed silently. It was ironic that he ruined a person's life but only received a few words of criticism. There was no need to take an exam to be a parent. This was the most terrible thing in the world.
After taking the last puff of her cigarette, Sang Luo regained her energy. She stretched and said, "Let's go, Master. Let's finish this case."
Ma Shi Tu also nodded: "You go downstairs first, I will go back to the office to get the car keys, and then we will drive to find the grave."
After driving for a while, the two arrived at the farmland that Zheng Longmen mentioned. Sure enough, they saw a newly erected grave in the field. Ma Shi Tu turned on the flashlight, threw a shovel to Sang Luo, and the two started digging together.
Since the workload was a bit heavy this time, Ma Shi Tu also gathered several enthusiastic people from the nearby area. Everyone worked together and soon dug up the grave.
Sure enough, there was a lion cartoon mask and a pistol on the deceased's coffin. The moment he saw the gun, Ma Shi Tu hurriedly asked everyone to move away. He put on gloves and carefully picked up the gun. He looked at it carefully and finally confirmed that it was a simulated toy gun. Only then did Sang Luo breathe a sigh of relief and put the gun in an evidence bag.
The lion headgear is not an ordinary children's headgear. The space inside is enough to accommodate an adult's head. Ma Shi Tu was very surprised: "This-this thing is not for children to play with, right? What is it used for, a circus performance?"
Sang Luo couldn't give an answer either, and no other useful clues were found in the grave, so the two had to fill it up. Then they thanked the people who helped them and returned to the car with the evidence.
Ma Shi Tu drove away from the farmland and returned to Chuncha Lane, visiting the building materials stores one by one. Finally, the owner of a store said that he had seen Zheng Wutong. His confession was the same as Zheng Wutong's. At midnight on the 31st, Zheng Wutong knocked on the door late to buy cement, and the quantity he bought was very small. The boss got up from the bed and opened the door for him. After he got the cement, he ran away quickly.
At 11 o'clock in the evening, the master and the apprentice finished their visit and sat in the car tiredly discussing the case. Sang Luo counted on his fingers and said, "Although the murderer has been found, there are still many doubts in the case. Where did the gun and the hood come from? How did Zheng Longmen know that there was a game shop in the family building? He lost control of his emotions that night. Could he really have committed the crime so rationally?"
Ma Shi Tu did not answer. He picked up the gun and examined it carefully under the light. "It's so real, just like the real thing. I was shocked when I first saw it. I have asked all the toy stores in the city these days, and no store sells such toys. To be honest, this doesn't look like a child's toy at all!"
Sang Luo agreed, "Yes, this thing should not be cheap. Zheng Longmen has no money on him, so he must have robbed it from somewhere. Since someone has lost such a valuable thing, why didn't he call the police?"
Ma Shi Tu sighed and put down the evidence: "Only Zheng Longmen knows all this. I will go to see his condition tomorrow. I hope he can get better. If he still knows nothing, then I am afraid we will not be able to know the details of the case. Just like you said, it is difficult to fully restore the details of the case when it is committed by a madman. Even if a god comes, it will be of no use!"
Sang Luo nodded, still feeling a little disappointed. Ma Shi Tu patted her on the shoulder and said, "Don't think about anything. Your health is the capital of the revolution. Your most important thing now is to go home and sleep!"
The car drove back to the police station. Ma Shi Tu went upstairs and delivered the physical evidence to the evidence room. Sang Luo went home alone. She was too lazy to wash up, so she just took off her clothes and fell asleep. However, she felt depressed and couldn't fall asleep.
Before midnight, the shrill alarm clock rang again.
Sang Luo sat up immediately and saw the dictionary on the desk was turning pages automatically.
