Chapter 68 Chapter 67

On the morning of January 3, Forensic Chen hurried into Gao Dong's office and closed the door. His expression was not very good. Gao Dong glanced at him, and asked in a deep voice, "Did the DNA test result come out?" Forensic doctor Chen said in a low voice: "The DNA comparison results of blood, urine, and hair collected at Gu Yuan's home are consistent with the body shot in the head at the death scene, but Gu Yuan is kept in the medical examination records of the hospital. The blood type is type A, while the blood type of the corpse at the scene is type O." Gao Dong clenched his fists and shook, stood up, bit his lips angrily and said, "Sure enough, this bastard is not dead!"

Forensic Chen was puzzled: "But this is strange. When arresting Gu Yuan, the special police obviously heard him talking inside, and rushed in after hearing the shooting. If he was not dead, no one would Will be willing to play the show, die in his place and let him escape." Gao Dong said: "Zhang Yiang already told me about Gu Yuan's actions on December 31st. At noon that day, he probably heard the news of Ye Yuanchao's death, so he immediately asked for a leave of absence, and then went to the school physics department. In the laboratory, according to the teacher on duty, he seemed to have taken some wires and left. The teacher on duty thought he was needed for teaching and did not ask. After he left the school, he went back and forth between the dormitory and his new house several times. I went to the gas station again, took a few big plastic buckets, and filled up more than 600 yuan of gasoline. Then I went to kill Shen Xiaoxian's family."

Gao Dong paused, and continued: "He emptied all the cash and jewelry gold of Shen Xiaoxian's family. Logically, he should want to abscond, but why did he arrest Shen Hao again and call us the next day? Suicide again, burning Shen Hao alive? Isn’t this contradicting his behavior of taking away cash and gold? The day before yesterday Zhang Yiang speculated that maybe Gu Yuan originally wanted to abscond, but later he felt that he could not escape and gave up. But now that the investigation is clear, he I went to buy gasoline that afternoon, and I thought about it that afternoon. It wasn’t that he thought he couldn’t escape, so he died together. He just played a space-time trick and tricked us all, this beast!”

Chen Fayi couldn't figure it out: "So, Gu Yuan wasn't in the room that day? But his voice and his shooting." "It's not what we thought at all. There are three mobile phones next to the body, two of which are very close. I judge that he used these two mobile phones to create the illusion that he was in the house. He used his mobile phone to talk to us. Talk, and then turn on the loudspeaker. Take out the other two mobile phones, and after dialing each other, turn on the loudspeaker function. Then put his own mobile phone and the second mobile phone facing each other on the ground, holding the third mobile phone Only the mobile phone left the house and continued to talk. In this way, the sound of his talking on the third mobile phone outside the house was called to the second mobile phone on the ground, and then transmitted to his own mobile phone. Finally, he continued to talk to us. That is to say, when he called us, he used three mobile phones in total. His own mobile phone and the second mobile phone were placed on the ground facing each other. Three mobile phones left the house."

Gao Dong said: "I re-listened to the recording of his call with me that day. Not long after the recording started, he said he was going to take a pee. At this time, there was the sound of his mobile phone being placed on the ground. At that time, it was just an excuse for him to pee. Stop talking for a while, because if we did, we would hear two of his voices and become suspicious. After he left the house, he continued to talk. Halfway through the call, I heard a horn. At that time, I thought he was standing by the window, but no I saw him. At that time, I vaguely felt that something was wrong, but now I want to understand, because there was no car passing by us at the time, how could there be a horn sound in his mobile phone? Because he is already on the road at the moment. He Why did you have to call me for so long? It was because once the phone was hung up, he couldn’t call me again, and no one would answer when I called. That’s why he kept talking to me. I was glad he was fooled at the time, I wanted to delay his time and distract him, but I didn't expect him to play tricks on me instead."

Forensic doctor Chen said: "However, there is a prerequisite for his design to do this. He knows that we will use the mobile phone location method to check his location, so that he can call us first, and then use three mobile phones to pretend that he is still there. I was calling us in the house, but I actually had the illusion that I had left.” "Maybe you can guess. In general kidnapping cases, if our police don't know the location of the other party, we will use the mobile phone to locate it." Gao Dong will never know that Gu Yuan's inspiration for designing this space-time trick is that his student Zeng Huihui told him that the police can now pinpoint the location of the mobile phone holder within two minutes of turning it on.

Forensic Chen nodded and said, "But who shot in the end?" "Nobody fired at all." "The gunshots were faked from the mobile phone too? The police outside the door should be able to hear it, right?" Gao Dong shook his head, took out a photo of the scene, pointed to the broken balloon in the corner, and said, "The gunshot came from the explosion of the balloon. Look at the scene, except for the two mobile phones facing each other, there is no Is there a mobile phone? There are batteries, spark plugs, wires, touch switches and other burnt leftovers. I guess Gu Yuan may have set the phone to vibrate and connected it to the wires, touch switches, batteries, and spark plugs. He Finally, I dialed the mobile phone, and after the mobile phone vibrated, the mechanism was triggered, the spark plug discharged, and the gasoline in the room was instantly ignited, so that the balloon exploded, making a gunshot sound. For him, a physics teacher, this kind of thing couldn’t be easier.”

"So how can he guarantee the final detonation time? He is no longer in the house, and I believe he dare not hide nearby to observe. How can he guarantee that our police will not rush into the house before he decides to detonate?" "It's very easy. Both mobile phones on the ground have their loudspeakers turned on. We can hear the sound in the house, and he can also hear the sound in the house on the other side. The doors and windows are tightly closed. We want to break into the house." When entering the house, there must be a loud noise. As soon as he hears the abnormal noise, he can immediately call the trigger mechanism."

Gao Dong continued: "Also, why did he use so much gasoline? It was to burn the body beyond recognition, and we couldn't identify him. And the toothbrush in his dormitory was covered with blood, urine, and hair on the bed. It was the dead man. Yes, he deliberately arranged it for us to do DNA testing. In addition, in the room at the scene, there were all kinds of messy piles of sundries on the ground. The more things become more and more messy, we will not notice that the batteries and wires thrown on the ground are mechanisms designed by him. Everything has been burned to ashes, the mobile phone on the ground has become rotten plastic, and the switch wires have been blown out. People, how can you tell that this is something he designed in advance? If you didn't collect the DNA information of his dormitory so smoothly that made me suspicious, I wouldn't have thought so much at all."

Forensic Chen sighed, "This guy is really smart." Gao Dong let out a sigh of relief: "This bastard is really smart. Looking back now, every time we directly investigate the results, he wants us to investigate them. To give false testimony to Ye Yuanchao, he wants us to We checked the shoes and computer, and we did. In Hu Haiping’s case, he left glass glue to make us think that the stone slabs fell from the fifth floor, which is what we thought at first. In Shao Xiaobing’s case, he left clear glass on the hillside. The footprints of Shao Xiaobing also wanted us to think that Shao Xiaobing committed suicide. As a result, he couldn’t deny that it was suicide. This time, he wanted me to call him, and I did as he wanted. He wanted us to think that there was a shooting inside Yes, we believed it. He wanted us to do a DNA test, and we did it again. This bastard is so smart, we will cooperate with him in everything he thinks, hey, no wonder the case is done like this.”

Chen Forensic Doctor said: "Boss, what should we do now? Overturn the case and re-arrest?" Gao Dong smiled wryly and shook his head, and stood by the window. After a while, he reluctantly made a decision: "Destroy his school and hospital medical records." "Destroyed?" Forensic Chen was surprised. "The case is closed." "But...but isn't he still dead?" Gao Dong said helplessly: "He called me that day, and actually said a lot of voice-overs that others couldn't understand. He kept begging me, 'give me a way to survive, and I promise to keep my name anonymous and never commit crimes again.' At that time I I mistakenly thought that he was out of his mind, but now I know that his words are for the future. Why did he explain all the crimes so frankly later? Ask me if I have any questions. Because if he doesn’t answer, I’m afraid there will be There are some crimes that we can never figure out. He made it so clear that he helped me to close the case. Now that he has run away, where can he be caught? He threw jewelry and a gold bar at the scene, and burned hundreds of thousands of dollars. Shen Xiaoxian This is the only valuable thing at home? Who would believe it? There is also Shao Xiaobing’s family, he must have taken a lot of things from the safe. The jewelry gold he threw on the ground is at least two or three kilograms worth millions, which shows that he still has a lot of money on him. How much money did he bring, how much gold? He said that he would never commit a crime again, and since then he has been anonymous, and has brought money for food and drink all his life. Where can I catch him? Look at how many people they sent and how much they spent in arresting Zhou in X Province Nian? The one named Zhou is nothing more than a gangster, can he be compared to Gu Yuan? This bastard is smart, if you want to catch him, it's not easy!" Gao Dong sighed, walked over and patted Forensic Chen on the shoulder, and said, "It's not that I don't want to arrest him, I can't help it. You are the only one in the city bureau who has followed me for more than ten years, and I can only tell you some things. After this case, many leaders were extremely dissatisfied with me. Although my father-in-law put in a lot of energy, I couldn’t get away with this punishment. I heard that next year I will be transferred to the head of the Criminal Investigation Branch of the Provincial Department. They said it was a transfer at the same level , the power is not comparable to the deputy director of the Listing Bureau. If this case is not closed, and Gu Yuan is still alive, how can I explain it? Will I have to spend my whole life in Ning County?" He shook his head with a wry smile, "Forget it, that day I If you verbally agree to him, this time it will be considered that you really agree to him and let him live." "What if Gu Yuan reappears in the future?" "Impossible. It doesn't matter if it happens, as long as it takes longer, you won't be held accountable if things go too far. After all, everyone is convinced that Gu Yuan shot himself that day. Everyone saw it, and everyone can testify .” Fayi Chen nodded in understanding, and said, "This is also an unavoidable choice. In comparison, it's better to deal with it this way." Gao Dong nodded, and said: "After Shao Xiaobing's wife is dug out in the next few days, the case will be completely closed. Anyway, it's already like this, and now I can only do more to make up for it. Later, I will ask Jiang Wei to clear the case of Ning County's innocence in recent years. Find out the top outstanding cases, and see which ones can be blamed on Gu Yuan, it can be regarded as more achievements." He smiled wryly, and looked out the window: "After the case is completely closed, even if Gu Yuan walks in front of me, I don't want to recognize him." On January 4, after the New Year's Day holiday, Ning County No. 1 Middle School resumed classes. All the teachers and students in the school knew about Gu Yuan. At noon, several students in Gu Yuan's class gathered in the corridor to discuss. One person asked, "Did Teacher Gu really kill someone? The principal was also involved?" Zeng Huihui nodded: "My dad said that Mr. Gu killed someone. I don't know how deeply the principal was involved." A boy laughed: "I never thought that Gu Yuan who taught us is a murderer." Zeng Huihui glared at him angrily: "No! Mr. Gu is a good person, he must have a reason for killing someone!" The boy continued to laugh: "Can you kill so many people if you have a hard time? There are still good people in murderers?" At this time, Chen Xiang from the next class passed by, his face was very ugly, all day today, he heard the people next to him arguing whether Teacher Gu was a good person or not, and why he killed people.In his heart, Teacher Gu is the best teacher he has ever seen.But since that incident, he has been careful in everything he does in school, not daring to get into any trouble.He really wanted to argue for Teacher Gu, but he didn't dare to conflict with other students. Zeng Huihui's eyes turned red all of a sudden, and she said loudly, "Ms. Gu is a good person, Mr. Gu is a good teacher! It must be!" A girl next to her grabbed Zeng Huihui, gave the boy a contemptuous look, and said to Zeng Huihui, "Don't pay attention to him, such a heartless person, we all believe that Teacher Gu is a good person. By the way, I heard that Teacher Gu took away the corrupt officials. How much money does the family have?" Chen Xiang stood there, stunned for a moment, as if he remembered something. Zeng Huihui held back her tears, nodded and said, "But they were all burned by fire." "It seems that on the wall of Mr. Gu's house, there was a last word written in chalk at the end. What did you write?" "My dad said that no one can understand the meaning of that line." "What exactly is written?" Zeng Huihui was puzzled and said: "Brine chicken, so delicious." In an instant, Chen Xiang stood in place, and in the next second, he couldn't control himself anymore, rushed into the toilet like crazy, opened the door of the cubicle, and locked himself in, tears streaming down his face.
