Chapter 10 Chapter 9 Bug

This may be the most dumbfounding case Li Conan has ever seen. A father and son were simultaneously considered suspects in two seemingly unrelated but interrelated murders within three days.On the father's side, there is conclusive evidence, but he refuses to admit it; on the son's side, there is no real evidence, but in the limited communication, his conversations and lies involving Zhang Huijia frequently appeared, and he is still missing now. It is said that they are related to each other because Zhang Huijia also visited Xing Yuemin on the day Liu Yibang's case happened. Li Cong'an first investigated Xing Yuemin's situation according to the path of love killing.Xing Yuemin's mobile phone communication record survey results are not good. The people he called on the mobile phone, let alone women, are pitifully few even men.Li Con'an even thought about whether he was gay, but he quickly denied it, because Xing Yuemin had only two sources of calls, the school teacher and the parents at home. On the day before Liu Yibang was killed, he received a strange call. The phone call lasted about five or six minutes.When I went to check this strange mobile phone number, I found that it was only used once, which was to call Xing Yuemin, and then it was never used again.Because it is a recharge number bought from a mobile stall, there is no way to confirm the user.

How should I put it, this is a doubtful point, and it is still a very big doubtful point.Someone bought a special number just to call Xing Yuemin.This is a very strange phenomenon. Ordinary people, who would buy a mobile phone card to make calls?If you make a mistake, you won't have to talk for so long. Could it be that mysterious person?Li Cong'an thought.This shows that there is indeed a problem with Xing Yuemin, but this clue is broken. On the second day, the task force returning from the investigation not only did not hear any more good news, but was completely in trouble.The policemen who were dispatched several times did not gain anything.The investigation of the social relationship between Zhang Huijia and Xing Yuemin on a larger scale did not provide any clues worthy of further investigation.They lived in their own worlds. They started with their student credit cards and checked the places they frequented, but there was no intersection at all. Zhang Huijia's parents also said that they had never heard their daughter mention this person named Xing Yuemin.

Regarding the computer competition, Li Cong'an also mobilized his staff. His inspiration for this came from Japanese campus mystery novels. In those novels, students often design a whole set of unimaginable ways to kill people because of some trivial things.But the results were not as expected.The rules of the competition are very strict and transparent. According to the organizer, there is no possibility of unfair competition. We encourage students to put friendship first and competition second. Everything stays in place. Li Con'an really couldn't find any connection between Xing Yuemin and Zhang Huijia, let alone that mysterious person.Are these three different events?Liu Yibang's murder case, Zhang Huijia's murder case, and Xing Yuemin's disappearance case are independent of each other.Li Cong'an's confidence was shaken.

Near noon, the director had a talk with him and asked about the progress of the case.Due to the influence of the Internet, the media was moved by the news. The spokesperson had already learned the details of the case with him alone yesterday, and prepared countermeasures.Originally, Li Cong'an was waiting to be criticized, but the director didn't expect to say anything. He just listened to Li Cong'an finish the case, and then said some words of encouragement, such as solving the case as soon as possible, and let Li Cong'an go back. Back in the office, Li Cong'an went to the window to smoke. The investigators who insisted on working at their posts relied on smoking one after another to maintain their condition. The table was full of instant noodles and empty lunch boxes.

After putting off the cigarette for a while, Li Cong'an smoked it again by himself, and then sat back in his seat.Now there is only one point that connects the three events. Zhang Huijia once went to Xing Yuemin on the day Liu Yibang was killed, and he thought of this again. Li Conan put the case in order from the beginning: first, a mysterious person called Xing Yuemin; After the Liu Yibang case, Xing Yuemin provided the most important evidence, the dagger, which completely locked Wan Jipeng in the cell; the reason why he did this was because he wanted to kill his stepfather. I once suspected that Xing Yuemin's mother and son teamed up to frame Wan Jipeng; but after interviewing, they found that they had no time to commit the crime; Zhang Huijia came to Xing Yuemin's house on the third day after Liu Yibang's incident; Xing Yuemin lied and denied seeing Zhang Huijia; the next day Zhang Huijia's body It was discovered that a letter to the mysterious person appeared on the Internet; now Xing Yuemin is also missing.

Li Conan thought about it, and sat up straight from the chair involuntarily. He suddenly discovered that these three events, even though they have little connection, can be twisted together so smoothly, just like the outline of a mystery novel. plot. He took out a piece of paper and wrote down the thoughts in his mind after processing.He changed it several times, and what finally appeared in front of his eyes was such a process: 1. First, the mysterious person called Xing Yuemin, planning to kill Liu Yibang and frame Wan Jipeng. 2. On the second day, Liu Yibang who lived downstairs in his house was killed. The murderer was a mysterious person, not Wan Jipeng.

3. At the same time, when Bai Sumei and Xing Yuemin came to the school, they had their alibi. 4. Zhang Huijia went to Xing Yuemin that day because of the competition, and may have found a clue. 5. After the Liu Yibang case happened, Xing Yuemin provided the most important evidence, the dagger, which completely locked Wan Jipeng in the cell. 6. The reason why he did this was because he really wanted to kill his stepfather. Because he had an alibi, he could say it openly. 7. I once suspected that Xing Yuemin's mother and son teamed up to frame Wan Jipeng; but after interviewing, it was found that they had no time to commit the crime, because the crime was committed by a mysterious person.

8. On the third day after Liu Yibang's incident, Zhang Huijia came to Xing Yuemin's house again, and happened to find a clue again. 9. Xing Yuemin lied and denied meeting Zhang Huijia, because it touched him. 10. Zhang Huijia's body was found the next day, and Xing Yuemin wanted to kill her to silence her, and later sent a letter to the mysterious person on the Internet. 11. Now Xing Yuemin is also missing. Li Conan looked at the words on the paper, and some assumptions and reasoning seemed to make sense, so it seems that Xing Yuemin killed Zhang Huijia not because of love, but because she accidentally broke Xing Yuemin's plan?

But there is one big mystery.According to this reasoning, Xing Yuemin killed Zhang Huijia because she discovered her conspiracy, but why did she write a "letter" to meet the mysterious person?What kind of identity is the mysterious person?Why do you want to help Xing Yuemin complete the plan?If it was a killer who used money to eliminate disasters, then there was no need to meet. Besides, Yang Jingjing also said that this was done by a novice. If it is a familiar person, it must be a very close person, so why does the mysterious person refuse to meet Xing Yuemin?However, the investigation of Xing Yuemin's social relationship found that there was no trace of this mysterious person at all.

If this question cannot be answered, then the reasoning on paper cannot be established.Li Con'an thought for a while, but there was still no result. He was a little disappointed and drew a big question mark on the paper. The takeaway dumplings are here, they are from Old Wang's at the corner.Lao Wang is from Shandong. When he went out to work, he met a local girl who went to the south. The two worked in a shoe factory, saved a little money, and came back here to open a dumpling restaurant.Because it is hand-rolled leather, it is quite chewy, and the price is surprisingly cheap, so once the criminal police team encounters a case that lasts all night, they will order takeaway from his home from time to time for convenience.

Lao Wang was already very familiar with the Public Security Bureau. He walked into the gate of the criminal police team with a big pot, opened the pot, and steamed the warmth of the room. The smell of rice soup was accompanied by the sour taste of mature vinegar. In everyone's nose. "Why is it so long today, you want to starve us to death!" The young policeman stepped forward, eagerly fished out one, put it in his mouth, and sucked his saliva with his neck crooked from being burned. "Hehe, slow down, slow down," Old Wang is an honest man, not talking in circles, "The shop has been busy all the time, so I finally found time to run out!" "So, it's better to do a small business. There is something to look forward to. Maybe it will become the pride of you Shandong people at some point!" "Small business, small business." Lao Wang couldn't close his mouth with a smile, "You are busy, I'll go first, and I'll get the pot later!" "Wait, I don't want money again, right? It happens every time, so we have to send it to you!" "I don't have a lot of money," Lao Wang continued to laugh, "You have helped me so much!" He was talking about a few hooligans who went to the dumpling restaurant to make trouble last year and were arrested by a few policemen who were eating in the restaurant. As a matter of fact, Lao Wang always wanted to thank everyone, so the money for dumplings was forced by the criminal police every time. "One size fits all, that's what we should do. Besides, we also have discipline, and don't take stitches from the masses!" "I have to treat you to dinner today!" Lao Wang stood there and said stubbornly. "how do I say this?" "Hehe, how should I put it, I'm sorry, my daughter-in-law is pregnant!" "Pregnant again?" "What does it mean to be pregnant again?" Another policeman corrected, "Old Wang has never had a child." "Yes, yes, look at my brain, it's alright, old Wang, I'm going to be strong, I'm going to be a father if I don't pay attention!" Old Wang still stood there giggling. The policeman turned his head to look at Li Cong'an: "What about the captain, isn't this a mistake?" Li Cong'an smiled: "Okay, we'll take it!" After Pharaoh left, everyone rushed to the table. "Captain, come quickly, if you don't come, you will be eaten up by these boys!" "It's okay, you guys eat first." Li Cong'an still smiled, he was looking for something on the table, and took out a document wrapped in a cowhide envelope from a stack of documents. "What are you looking for? Come and eat something!" "You eat first." Li Con'an waved his hand, he was still thinking about the previous reasoning, although he didn't get the result in the end, but if Liu Yibang was killed only because of framing Wan Jipeng, then he was too wronged. Li Cong'an opened the envelope, which contained Liu Yibang's files.Li Cong'an looked at it at a glance, his file was as clean as a blank sheet of paper, and a few sentences recorded a person's life.Perhaps there is no one who is more lonely than him. Graduated from junior high school, a foreigner, settled in this city about fifteen years ago, his parents are dead, never married, and has no brothers or sisters.According to the labor insurance records, he only worked in two factories, both of which did not have any technical requirements. One was in a state-owned flour mill and the other was in a freight company.I worked for one year and three years respectively, and the rest of the period was almost blank. Li Cong'an suddenly thought of Yang Jingjing saying that Liu Yibang had also been engaged in the work of "testing medicine".Since Wan Jipeng was arrested after the incident, the direction of the initial investigation was to find evidence and motives for Wan Jipeng's killing of Liu Yibang. On the contrary, he did not do a thorough research on the victim. Check again. He called Lao Liu, who was in charge of security. The industry of "drug testing" is buried underground. Although it is based on labor, it is not very humane after all. Neither the supply nor the demand side will show it off. It is not much brighter than those shady industries.Even Li Cong'an, who has been a criminal policeman for some years, is very unfamiliar with this. Lao Liu said that he had never been in contact with such a case, so he probably couldn't help with any substantive help, but he could ask.Li Cong'an said, let's do it first. After hanging up the phone, Li Conan stood up and went to the table to eat dumplings. Just as he was filling a bowl, a boy next to him stabbed Li Cong'an with his arm. "What for?" "Captain, look who's coming!" Li Cong'an looked outside the door, Yao Ruoxia was standing there dignifiedly. "How did you come?" Yao Ruoxia didn't answer, but smiled. She was holding a plastic bag with a flower pot in her hand, and a thermos bottle in her right hand. "Captain, can you give me your dumplings?" It turned out that the kid gave Li Cong'an another bow, and pointed to the thermos bottle in Yao Ruoxia's hand, "You have warm bento there!" "Looking for a draw!" The kid flashed over, and Li Cong'an walked towards Yao Ruoxia with a smile on his face. In the reception room, Li Conan drank the preserved egg porridge brought by Yao Ruoxia and asked, "Why are you here?" "I went to a client in the morning. I passed by here and came here. This is for your dad." Yao Ruoxia took out the potted plants from the plastic bag. "Aren't you going?" "Go, I have to go back to the store in the afternoon. It's inconvenient to carry it. You can just take it there. What should I say at night, are you coming to pick me up, or should we go separately?" "Let's go separately." Li Conan looked at the potted plants, Yao Ruoxia felt a little nervous. "I'm not sure. You—" Li Cong'an pointed to the potted plants, frowned, and Yao Ruoxia's heart beat faster. "I said, don't spoil the old man!" Li Conan put away the potted plants and put them under his feet, and continued to drink the porridge. "He is almost a fan of flowers!" Li Conan said jokingly. Yao Ruoxia let out a sigh of relief.
There is a 24-hour Yonghe Soymilk on the side of the road, diagonally opposite the gate of the Public Security Bureau.Looking from this window seat, it happened to be partially blocked by a big tree.After leaving the gate of the Public Security Bureau, Yao Ruoxia walked to the opposite side of the road, pretending to look at the puppets in the window, she confirmed from the reflection in the mirror that no one noticed her, and then turned into the soybean milk shop.She ordered a glass of juice and two egg tarts, and sat down there. This seat covers most of Yao Ruoxia's body, making it impossible for the policemen coming out of the branch to recognize her at a glance, and he can have a panoramic view of the gate by tilting his head, although it is expected that the effective distance of "Shunfenger No. Up to 1,500 meters, but if this position is safe enough, there is no need to test the extreme performance of the wind ear. She looked around the storefront.After falling in love with Li Cong'an, she has been monitoring him in a similar way, preparing for everything she does today. There is no suspicious person in the store. A pair of middle school students in school uniforms in the corner are embracing each other and whispering. From time to time, silver bell-like laughter will erupt. There are textbooks spread out on their desks; The old man in the hat was carefully sucking the small wontons in the bowl; there was also a driver in the uniform of a taxi company, eating vegetables and rice, and pouring cold soda into his mouth while chewing; The middle-aged woman is holding a small pot, waiting patiently for the noodles to be cooked. everything is normal. Yao Ruoxia took out the earplugs from her bag, and put the earplugs into her ears naturally like a bored girl listening to MP3.There was a noise coming from the earplugs. Yao Ruoxia reached into her bag and adjusted the equipment in her pocket. The noise gradually weakened, and the human voice gradually became clear, as if she had tuned to a clear radio station. The effect is not bad, Yao Ruoxia thought in her heart, she heard Li Cong'an talking, thank God, he didn't leave the potted plant in the reception room, but brought it back to the criminal police team. Yao Ruoxia intermittently listened to the movement in the criminal police team, but there was no information she wanted, they seemed to be talking about a case in the campus. "Have a better attitude!" She heard Li Cong'an say again. Halfway through the conversation, Li Cong'an answered another call, "I'll ask my mother when I go back," Li Cong'an said on the phone, "You know, she's retired, but you can ask their academic affairs office, I'll let you know as soon as we have any news!" After hanging up the phone, Li Cong'an smiled wryly, "It's all favors, his son will take the entrance exam next year and wants to enter a key middle school, so let's say hello in advance!" He seemed to be complaining to another policeman that Li Cong'an's mother died before she retired. Teaching Chinese in a key middle school. Still haven't talked about Liu Yibang's case, Yao Ruoxia has some confidence, it is estimated that the case has been closed. A few more people came in from the soybean milk shop. Yao Ruoxia looked at them, but she didn't recognize them. They were passers-by. She turned her attention back to her ears again, and Li Cong'an's voice came from the earbuds: "Wait for Liu Yibang's case!" Yao Ruoxia felt something was wrong. "Wait until Zhang Huijia's case has some clues!" Yao Ruoxia thought Zhang Huijia's name was very familiar, but she couldn't remember it for a while. She didn't know what it had to do with Liu Yibang's case. "This matter is quite big. I didn't expect the Internet to spread all of a sudden. This makes us very passive now. Therefore, technology also has advantages and disadvantages. If we put it in the past, what happened today would not happen." Yao Ruoxia was even more confused. It seemed that Liu Yibang's case was put on hold because of a student named Zhang Huijia. She didn't know the reason.She didn't bring a computer with her, so she couldn't access the Internet at this time. Yao Ruoxia was uncertain, so she took a sip of the orange juice in the cup, got up, stood up, and walked out the door. Still no one found out.After turning two streets, Yao Ruoxia saw an Internet cafe.She turned on a machine and typed Zhang Huijia's name on Baidu.Hundreds of messages about Zhang Huijia popped up on the Internet, saying that she died at the hands of a perverted killer. The killer said that he had killed a person and uploaded the location of the corpse on the Internet, which has been confirmed to be true.After the murderer finished speaking on the forum, he added a sentence: Zhang Huijia is dead, I want to see you! Zhang Huijia?Yao Ruoxia felt that the name was familiar, so she continued to browse the webpage, and the report said that she was a student of Tongzhou University, and the title of "Xing Yuemin, a student of Tongzhou University suspected of being the real culprit in Zhang Huijia's case" stood out. She suddenly remembered who this Zhang Huijia was. Yao Ruoxia looked at the computer blankly, but her mood was hard to calm down. She thought, she knew what happened!
