Chapter 22 Section five

The next afternoon, the sky was gloomy, and it seemed that it was going to rain heavily.I hung a signboard on the stairs on the second floor of the coffee bar and made a big pot of ebony tea.Qin Siwei personally delivered the invitation card for me early in the morning, and the guests are coming at this moment. There were light footsteps on the stairs, Wei Dagang followed the waiter, walked up step by step, and kept looking around. "Captain Qin asked me to come over." He said timidly, "He said it was about my brother." "Wait a minute, there are still some friends." I led him to a seat and poured him a cup of tea.He took the teacup with both hands and licked his lips shyly.

"Dagang, hasn't your brother been married for so many years?" I asked him. "No, the family keeps urging him, but he always says he's not in a hurry, and he gets unhappy if he talks too much." "You don't have a girlfriend either?" "No, the family introduced him to him, but he didn't see him. In the past few years, their leaders have also introduced him, but Ergang is very annoyed by this kind of thing, and secretly scolded them for meddling in their own business." "Then do you know that he has the habit of keeping a diary?"

He nodded: "He has started to write a diary in the past few years, but I remember that he didn't have this habit when he was a child." The arrival of Fan Rong interrupted my conversation with Wei Dagang: "Where is Police Officer Qin?" He couldn't help being a little strange when he saw Wei Dagang and me. "He'll be there in a while. Sit down and have a sip of tea first." I asked him to take a seat. "Dagang, I heard you plan to go home?" Fan Rong asked Wei Dagang. "I bought a ticket for tomorrow morning, and I will go back to take care of my brother's funeral." Wei Dagang whispered.

"need my help?" "No, no, thank you." "You guys came early enough." Wu Jingyi poked his head out from the stairs, greeted us loudly, and didn't forget to ask me, "Where's Captain Qin? He asked me to come here before two o'clock." "I'll be there soon." I dealt with it. "Sit down and drink some water first." Fan Rong poured him a cup of tea, "This tea is sweet and delicious." "Ms. Wu, have you met Professor Wei's brother before?" I asked Wu Jingyi. "Oh, I've seen it a few times." He and Wei Dagang shook hands symbolically.

After chatting about some empty topics like the weather, Qin Siwei, whom everyone was looking forward to, finally came.Behind him, Qiu Bin's expression was as gloomy as the weather. "I'm sorry to keep you waiting for so long." Qin Siwei greeted everyone with a pleasant face, "I just stopped by to pick up Teacher Qiu, but got stuck in traffic." "Officer Qin, is there anything special about calling us here?" Wu Jingyi cut to the chase, "I still have class at four o'clock in the afternoon." "Don't worry, Mr. Wu, I won't delay you for a long time." Qin Siwei said righteously, "I mainly have a few questions today and I want to check with you."

He sat down and drank a cup of tea: "The night before yesterday, Professor Wei Pingqing was murdered at home. Everyone knew about it. In addition, we learned that the day before the incident, someone sent a message to all the teachers of the School of Economics and the leaders of the University of Technology. An anonymous e-mail was sent, exposing the fact that Professor Wei plagiarized the academic achievements of foreign scholars." Qin Siwei took out a stack of materials from his purse: "We tracked down the whereabouts of the anonymous letter and found that it was mass-sent from a free mailbox of Netease, and this mailbox had been canceled at 11 o'clock the night before yesterday. But at the service provider, We still found the registration information of the email address." He raised his head and smiled, "Mr. Fan, the user information shows that it is an email address you registered in 2003."

Fan Rong almost jumped up as if being kicked by someone: "It's not me, it's not me! I haven't used that mailbox for more than two years. Someone stole my password and tried to frame me!" "Yeah, who would be so stupid to send an anonymous letter using the mailbox registered with his real name." Wu Jingyi echoed, "Captain Qin, this is a smokescreen deliberately placed by someone." "It seems that Mr. Wu is very clear about the reason for this?" Qin Siwei looked at him coldly, "I still have a document here, I'm afraid you will be more interested." We waved in front of us, "The call record provided by the mobile company, Teacher Fan called you at 10:19 the night before yesterday, the call lasted six minutes, and then you returned to the University of Technology at 10:38. Can you explain to us what is the connection here?"

Without waiting for Wu Jingyi's answer, he turned to Fan Rong: "Teacher Fan, since you were so drunk the day before yesterday, why did you call Teacher Wu?" "I... I'm drunk, so I don't remember." Fan Rong gritted his teeth and said, "Anyway, I didn't send an anonymous letter, and it has nothing to do with Wei Pingqing's death. You can't wrong a good person with just one email or one phone call!" Wu Jingyi glared at Qin Siwei without saying a word. "Mr. Fan, it's better for you to tell the truth." I advised Fan Rong, "You drank some wine the night before yesterday, but you were not drunk. After you got home, you turned on the computer, and then sent the letter that made you feel extremely angry. After reading the anonymous letter carefully, I suddenly found that the email address you sent was registered by yourself a few years ago. In a hurry, you called Mr. Wu, who also felt that the situation was serious, so he drove back and discussed with you Countermeasures. After discussing for a long time, you finally decided to cancel this mailbox to avoid being found out, and to take the blame for others. After the agreement, Teacher Wu left your house around eleven o'clock, but forgot the purse when he left."

Wu Jingyi and Fan Rong stared at me in shock, but I ignored their surprise: "Early this morning, Teacher Fan received the news of Wei Pingqing's murder, and I felt palpitated thinking that the police would definitely investigate your whereabouts last night. And Teacher Wu It is impossible not to be suspected twice, so you called Mr. Wu and made up a story about being drunk and failing to pick up the bag. The two of you cooperated well, but you did not do enough in a few small details, which showed your flaws. .” "I didn't send an anonymous letter." Fan Rong repeated stubbornly, "I have already..."

"I don't care about anonymous letters." I interrupted him, "Teacher Fan, since you were not drunk yesterday, can you tell the truth, did you hear anything?" Fan Rong shook his head firmly: "I really didn't hear anything." I asked Wu Jingyi: "When you left the professor's apartment, was the door of Wei Pingqing's house open or closed?" "It's closed." Wu Jingyi said without hesitation, "It was almost ten o'clock at the time. If his door was open, I would definitely go over and have a look." "Did you not drop by Professor Wei?" Qin Siwei asked him.

"What am I visiting him for?" Wu Jingyi said with a dark face, "What do you mean?!" "It's just a routine investigation." Qin Siwei said, "According to our analysis of the scene, after the murderer entered Wei Pingqing's house last night, the two had an argument. Wei Pingqing fell and hit his head on the glass coffee table, resulting in death. The murderer wanted to confuse us. Afterwards, the scene was cleaned and arranged specially. This person must be an acquaintance of Wei Pingqing." "You doubt me!" Wu Jingyi stood up aggressively, "Do you have evidence?" "Teacher Wu, calm down, calm down." I pulled him, "How about sitting down and listening to me tell you a story?" They all looked at me with distrustful eyes.I poured myself a full cup of ebony tea, took a sip, cleared my throat and said, "What Captain Qin just said was an inference based on the physical evidence at the scene. At first, I also thought it was a reasonable inference, but there are two The question has always puzzled me—first, why did the murderer take so much effort to clean up the scene? In fact, he just wanted to leave the body where it was. Accidental death. However, the murderer made such a fuss at the scene, which led the police to draw the conclusion of homicide in the first place, which is not at all like what Gao IQ did. Second, the police did not find any wine in Wei Pingqing's home It was later through Dagang that we found out that what Wei Pingqing was drinking was French wine, which was given to him by Teacher Fan a long time ago. This made me feel even more strange. Whether Wei Pingqing drank alcohol, we only needed to do a blood test You know, why did the murderer have to take away the drinking utensils?" I took a deep breath: "These two questions have troubled me for a long time, until later, I suddenly realized that I made a very mentally retarded mistake. The situation on the scene is real, but we look at the problem from a wrong angle. And in Under the premise of this wrong assumption, all the inferences must be wrong. Thinking of this, the whole case is as simple as a blank sheet of paper." They still stared at me without saying a word.I explained: "Wei Pingqing's wound is on the right side of the top of his head. If he was pushed down by the murderer and hit his head on the sharp corner of the coffee table, then the wound should be on the back of the head or forehead, or even the temple, and it is absolutely impossible. On top of the head. So, the murder weapon wasn't the glass coffee table at all. "I think the situation at the time of the crime should be like this—the murderer had an argument with Wei Pingqing, and Wei Pingqing drank too much wine and got up to go to the bathroom. At this time, the murderer suddenly rushed up from behind and strangled his neck——Wei Pingqing The bruises proved this. Wei Pingqing is a strong man. He pushed the murderer away. The murderer fell to the ground and hit the glass coffee table and was injured. As a result, the murderer was completely enraged, and he grabbed the wine bottle placed aside , hit Wei Pingqing's head fiercely. Wei Pingqing fell on the floor in front of the bathroom and died on the spot. Afterwards, in order to cover his own traces, the murderer wiped off the blood on the coffee table, took away the wine bottle used as the murder weapon, and The floor was cleaned carefully, and all the crumbs of the wine bottles scattered on the ground were cleaned up. This is the truth of Wei Pingqing's murder." "Impossible!" Qin Siwei said loudly, "The blood on the tea table has been proved to belong to Wei Pingqing!" "It should be the DNA that makes the same identification." I corrected him, "I have been a criminal policeman for so many years, don't you know that the DNA of identical twins is the same?" Qin Siwei gasped, and looked at Wei Dagang sitting next to him with almost fearful eyes.Qiu Bin covered his mouth with his hands and let out a vague exclamation.Wu Jingyi stared with a pair of goldfish eyes, looked at me, then at Wei Dagang.Wei Dagang just looked at me blankly and didn't speak. "Impossible! You made a mistake." Fan Rong patted the table and stood up, "I will believe anyone who killed Wei Pingqing, but Dagang will never kill his brother! You have no idea how good he is to his brother .” "Teacher Fan, I remember you told me that if the doorbell on the opposite side rang, you could hear it in your house. But on the day Wei Pingqing was killed, you didn't hear anything. What does this mean? It means that the murderer didn't ring the doorbell. He has the key to Wei Pingqing's house." "This..." Fan Rong was speechless. "I don't think your logic is wrong." Qin Siwei said hesitantly, "But, this is unreasonable. There must be a motive for killing people, right?" "This starts with Wei Pingqing's personality." I sighed softly, "Would you like to hear another story?" There was silence all around, even the sound of breathing could be heard clearly.I leaned on the sofa and said: "This story happened more than ten years ago. In a small mountain village in Hunan, there was a pair of twin brothers. They are both talented, hard-working children. It is a pity that the family is poor, so the old father reluctantly decided, Only one son is allowed to go to college, and the condition is to see who has better grades in the college entrance examination. Among the two brothers, the elder brother is a simple and honest man, because he often loses sleep at night because of worrying about his future; He is better than him, even his own brother. God is so blind, my brother has a fever because of a cold. Originally, this is not a serious illness, but he gave his brother a great opportunity - he took advantage of his family's unprepared, I tampered with my brother's medicine..." "Stop it!" Wei Dagang suddenly lost control of his emotions, covered his face and began to cry, "I never dreamed that it was Ergang who gave me laxatives, which prevented me from going to college! I am nineteen years old I went out to work as a coolie, and sent all the money I earned to him, for fear that he would not be able to eat well, wear clothes, or afford books at school. Now, he has developed and became a university professor, but what about me? For the rest of my life..." He stopped crying and wiped away the tears on his face: "Yes, I killed Er Gang. The day before yesterday, I was on night shift. I knew he was in a bad mood, so after the dormitory turned off the lights and locked the door at 11:30 in the evening, I secretly ran out from the side door, wanting to see him. When I arrived at his house, Er Gang was already so drunk that he was sitting on the ground crying. When he saw me, he pulled me and cried, saying that he had done it to himself, that he... ...He's sorry for me... I heard him say what happened back then, and my mind went blank for a moment. I..." He took off the baseball cap he had been wearing all the time, revealing a wound on the back of his head, "Wait When I woke up, I saw Ergang fell to the ground, and I was covered in blood. I knew I had caused a catastrophe. Fortunately, it was late at night and there was no one on campus. I quickly cleaned up the room and ran back to the dormitory. building." I wanted to comfort him a few words, but I didn't know what to say.Qin Siwei lowered his head and fiddled with the teacup, it seemed that he was having a fierce struggle in his heart. "Captain Qin, Dagang is a good man." Fan Rong held back the tears in his eyes, "Can you..." Qin Siwei was silent for a while, then raised his head and said, "Dagang, today is Xiying's host, and it's a private party. So if you turn yourself in now, I can pretend that nothing happened just now." "I... will surrender myself." "Let's go, Dagang, I'll accompany you." Fan Rong helped Wei Dagang to stand up. "I'll drive you there." Wu Jingyi followed them out. Looking at their backs, Qiu Bin asked Qin Siwei meaningfully: "Captain Qin, this seems a bit..." "Ms. Qiu understands French, right?" I smiled at him. "What do you mean?" Qiu Bin looked at me warily. "Of the twelve foreign language articles that Wei Pingqing plagiarized, nine were in French, that is to say, only three were in English. As you said, he didn't even change the titles of five papers, which means you can understand French. Well." I continued to smile, "You kept implying us from the very beginning that the anonymous letter was written by Fan Rong, so it was a good idea. So, I couldn't sleep last night, so I traced the IP that sent the anonymous letter address……" Qiu Bin stood up suddenly: "I don't understand what you're talking about!" After saying that, he ran downstairs like a swipe. "Go slowly, don't send it off." I waved at his back.
