Chapter 35: The Viper Murder Case (14) A loud bang...
【wrong】
The dictionary finally stopped at a certain page, and the word "wrong" emitted a faint light.
Wrong, they arrested the wrong person.
Sang Luo immediately thought of this sentence, and she lost all sleepiness. She simply got up, turned on the light, and started thinking about the whole case again.
From Nie Yu's report to the police at the beginning, to the testimony of the game shop owner later, and then to the murder plan written by Zheng Longmen himself, Sang Luo recalled every detail carefully and listed all the doubts. Suddenly, a sentence broke into her mind.
Why did that person say that during the interrogation?
According to his status, he shouldn't have said that.
If Sang Luo was right, that person was the murderer of the case. He misled the police and put all the suspicion on Zheng Longmen.
After thinking it all through, Sang Luo's mind suddenly became clear. She lay back on the bed. She wanted to get enough rest tonight so that she could make a comeback tomorrow!
The next morning, Sang Luo arrived at the office of Team 3 early, and everyone else was there too. Yuan Xiaohu reported on Zheng Longmen's situation. The chief physician of the psychiatric hospital diagnosed him and confirmed that he was indeed suffering from intermittent schizophrenia. Zheng Longmen was still manic after going to the hospital yesterday and beat up two nurses. The doctor gave him an injection of sedative. When Yuan Xiaohu left this morning, he was still in a coma and had not woken up yet.
Yuan Xiaohu asked a colleague from the second team to watch over Zheng Longmen for him. He went home, took a shower, changed his clothes, and then came to the bureau.
After a night of thinking, Ma Shi Tu began to doubt his conclusion: "Zheng Longmen's symptoms during the onset of his illness were violent beatings. How could he calmly commit a crime in this state?"
Then, he said what Sang Luo wanted to say: "--Did we catch the wrong person?"
Yuan Xiaohu and Xie Ling'er looked at each other and neither of them spoke. They did not participate in the investigation last night and no one dared to express an opinion.
"Master, I think so too," Sang Luo stood up and said, "The murderer is not Zheng Longmen, the real murderer is someone else!"
"Who could be the murderer?" Ma Shi Tu touched his chin and fell into thought. The owner of the game shop said that the man who came to rob that night was about 1.8 meters tall. There were only three people who fit his description. If it wasn't Zheng Longmen, then who could it be among the remaining two?
Fu Ainong had a motive for committing the crime and no alibi, but there was no small hole on his side to put the snake in. If it was him, how did he poison the animal?
As the husband, Nie Yu was the biggest beneficiary of this incident. He also had a motive for committing the crime, and it would have been easy for him to poison. If it was him, what about the testimony Zheng Wutong gave? Why did Zheng Longmen carry a snake home late at night?
After thinking about it, the two of them came up with an idea. Sang Luo and the master said in unison: "Fingerprints——"
At this point, we can only let the evidence speak for itself. Last night, Sang Luo and the master found a fake gun used by the murderer under the grave. The gun is made of metal, and fingerprints should be detectable on the gun. As long as the fingerprints are sent for identification, we will know who stole the snake on the night of the 30th, and this person is most likely the murderer.
Yuan Xiaohu interrupted and said, "Master, I am a little worried that the situation like last time will happen again. The murderer has anti-detection awareness. He wiped off his fingerprints and printed someone else's fingerprints to deliberately mislead us."
Ma Shi Tu nodded: "Even if there is such a possibility, we must do a fingerprint identification. This gun is the most important physical evidence in this case and must not be wasted."
Sang Luo comforted him, "I don't think so. In this era, DNA identification and fingerprint identification technology are not popular. Many grassroots police officers in backward areas don't know about such technology. The murderer is also likely unaware of it, so he may not wipe off his fingerprints after committing the crime."
Xie Linger agreed, "Yes, Shen Xueyao last time was really a special case. She was so studious, often reading newspapers, and could remember the contents of the newspapers at critical moments. How many people can be like her?"
After hearing what Sang Luo said, Yuan Xiaohu felt much more relieved. He still followed the old rules. He and Xie Ling'er were responsible for taking the fingerprints to the Municipal Bureau for identification. They had been there many times and were familiar faces in the Municipal Bureau, so it was more convenient for them to act.
After they left, Sang Luo and Ma Shi Tu stayed in the office waiting for news. Sang Luo turned to look at Ma Shi Tu and said, "Master, I have an idea. I want to take this opportunity to conduct another interrogation."
Ma Shi Tu showed a hint of surprise. Since the last case was solved, he gradually began to pay attention to the ideas proposed by this little apprentice: "Oh, you already know who the murderer is?"
Sang Luo bit her lip and said, "I'm still a little unsure, Master, let me interrogate him first. I want to interrogate Nie Yu——"
Nie Yu was once again taken to the interrogation room. He had lost count of how many times he had been in the interrogation room since the incident. Sang Luo and Ma Shi Tu were still in charge of the interrogation. The expression on Nie Yu's face had changed from sadness to despair. He sat on the chair, lowered his head deeply, as if he had given up hope on everything.
"Where were you on the night of the 30th, the day before the incident? What were you doing?" Sang Luo asked him this question.
Nie Yu said weakly, "Officer, I've already said it. I went home from get off work that day as usual, and then I never went out again. My husband and I had dinner and started to coax the child. Yaoyao kept crying, so we took turns holding her, singing nursery rhymes to her, and coaxing her to sleep. We didn't go to sleep until she fell asleep."
"Did you hear any noise next door on the night of the 30th?" Sang Luo asked.
According to Zheng Wutong, Zheng Longmen had a mental breakdown that night and slammed the door and left. If Nie Yu was really at home, he should have heard the sound.
Nie Yu knocked his head, he seemed to have a headache: "Oh, this happened several days ago, who remembers it, let me think about it..."
He thought for a long time before vaguely recalling, "The day before the incident, I seem to have some impression, it was very noisy that night, the neighbors were arguing, my child was so scared that he kept crying, my husband and I went to bed very late."
"Did you hear clearly what they were arguing about?" Sang Luo asked.
Nie Yu rubbed his face and said, "It's always like this next door. They're just arguing about the college entrance exam. I'm too lazy to listen to them."
Sang Luo pressed, "Can you tell me the details of their quarrel?"
Nie Yu began to get impatient: "This, how could I remember? Okay, okay, let me think about it... Well, at first the father and son started arguing, and the kid's mother was trying to mediate, and then as the argument went on, the kid next door started to go crazy again. Oh, he always goes crazy, did I tell you?"
"He was roaring and smashing things in the house. He kept saying he was going to kill someone. Then there was a loud noise and the house became quiet. I don't know what happened after that. I think I fell asleep."
"What about the next day? Did you hear any noise next door?" Sang Luo did not miss any details.
Nie Yu scratched his head: "Well... I don't have any impression, there should be no sound. I just remember that I was so sleepy the next morning that I almost didn't get up. If I knew that something like this would happen on this day, I shouldn't have left home..."
Nie Yu started crying again, and the auxiliary police officer beside him took him away. Only the master and the apprentice were left in the interrogation room. Ma Shi Tu looked at Sang Luo: "How is it, did you find anything?"
Sang Luo asked back: "Master, what do you think?"
Ma Shi Tu thought for a moment and said, "Regarding what happened on the night of the 30th, the testimonies of these two people are roughly consistent. First, a conflict broke out at home, then Zheng Longmen went crazy, and then there was a loud noise. It should be him slamming the door and leaving. This can prove that Zheng Wutong did not lie, but what happened afterwards is problematic——"
Ma Shi Tu expressed his guess: "Zheng Longmen was in a state of madness after he went out. He couldn't have committed the crime so calmly. Maybe Nie Yu also went out after that. He went to the game store to steal the snake, put it in a Coke bottle, and stuffed it into Zheng Longmen's hand."
"Nie Yu did this to get rid of his wife through Zheng Longmen. Maybe he knew that Zheng Longmen always complained about the noise of the children, so he took the initiative to give the poisonous snake to Zheng Longmen."
"On the night of the 30th, Zheng Longmen was unconscious and wandering around the street. Nie Yu stuffed a Coke bottle into his hand and sent him to the door of his house. Zheng Longmen regained his sanity after returning home. He didn't know where the poisonous snake came from, but since he had the snake, he could carry out his murder plan."
"So on the 31st, Nie Yu went to work as usual, and Zheng Longmen was alone at home. He opened a Coke bottle and sent the snake through a small hole into He Taohua's bedroom. He Taohua and her daughter were killed, and Nie Yu pretended to be unaware of the murder when he got home from get off work. In this way, he could get rid of his wife and children without any effort and get two insurance payments."
The analysis makes sense, but -
Sang Luo smiled slightly and said boldly: "Master, I think exactly the opposite of you."
"Oh?" Ma Shi Tu was surprised. He thought he already knew the truth, but he didn't expect Sang Luo to have other ideas. However, he didn't feel embarrassed at all. Instead, he encouraged Sang Luo to speak freely.
"That loud noise must be the sound of a door slamming?" Sang Luo expressed his thoughts.
Ma Shi Tu looked puzzled. "If it's not the sound of a door slamming, what else could it be? Since Nie Yu emphasized the loud noise, it must be very loud, not just the sound of something being smashed."
"Nie Yu just said that after a loud noise, the house instantly became quiet," Sang Luo analyzed. "If it was Zheng Longmen who slammed the door and left, then that obviously doesn't fit Nie Yu's description. Zheng Longmen was in a manic state. He ran out of the house and went crazy on the street, which was still very noisy for Nie Yu. The only thing that can make a crazy madman quiet instantly, apart from sedatives, is coma-"
"I think Zheng Longmen didn't run away that night, but was knocked unconscious by someone," Sang Luo picked up a pen and tapped his head, "That loud noise was not the sound of a door slamming, but the sound of a blunt object hitting his head."
"When we interrogated Zheng Longmen, he said he had no recollection of what he did on the night of the 30th and the day of the 31st. I thought it was because he was having a mental illness, but now it seems I was wrong. He didn't remember anything because he was in a coma that day and night."
