Chapter 5 Section five

A night of strong winds brought sporadic light snow, and when we woke up in the morning, the shrubs, flower beds and cars parked by the roadside outside the window were all covered with a layer of hoarfrost.The sun came out, but the sky was still gray.I sat on the balcony in a thick woolen shawl and read the news online.The gentle sun shines on the face, warm.A pot of coffee was brewing on the small table next to it, and the hot aroma drove away the chill. When it was almost noon, Qin Siwei came with a briefcase, his hair was messed up, and he didn't know if it was blown by the wind or he forgot to comb his hair in the morning.

"You are so laid back." He threw the briefcase on the table, leaned closer to the coffee machine and smelled it, "Is it... Mamba?" "Okay, I can tell it's a mamba. I reward you with a cup of coffee." I poured him a cup of coffee and pushed the milk jug and sugar jug ​​in front of him. Qin Siwei threw two cubes of sugar into the cup and said, "You are so comfortable. I really envy you, drinking coffee, basking in the sun, and surfing the Internet. I have been busy since six o'clock in the morning. Operation." "Be kind, who is not busy with your case?" I tidied up my shawl, "Tell me, how is the investigation going?"

"The few things you mentioned are basically checked." He took out a few documents from his briefcase, "There is one thing that is a little strange." "The concentration of the drug in the Golden Rain wine glass is inconsistent with the concentration of the drug in his body, right?" I raised my eyebrows at him. "Yes, it's different. The drug concentration in the wine glass is only a quarter of the drug concentration in his body. How do you know?" Qin Siwei looked at me in surprise, and the document in his hand almost fell to the ground. "Because it's only in this way that everything is reasonable." I smiled, "Let's put the matter of Jin Yu aside and talk about Chen Xuefang. Now you believe that she didn't commit suicide, right?"

"Yes, she didn't commit suicide. We detected nalatamine in the sewer of her kitchen, which means that someone cleaned the poisoned utensils there not long ago, and it is probably Chen Xuefang's water glass." He handed me the test report, " This person is too cunning, after cleaning the water cup, he took Chen Xuefang's handprint to print his fingerprints, and he almost fooled him. But I still can't figure out how he did it." "You mean the time when the crime was committed." I poured myself some coffee, "Yang Jianmei, Li He, Liu Yang, did you know the whereabouts of these people yesterday morning?"

"Yang Jianmei said that she went out at nine o'clock yesterday morning, took the bus to the bar, and arrived at the 'Walden Lake' at about nine forty. Li He drove by himself, and left home at nine fifty, and around ten ten Arrive at Shichahai, and then walk to the bar. Liu Yang took a taxi to Shichahai at around 10 o'clock in the area of ​​the Hangtian Bridge. He arrived at around 10:20, but the taxi got lost in the alley. We have asked to pick him up driver, the driver testified that he did not lie." "A call from Chen Xuefang's house came to your mobile phone at 10:12, right?"

"Yes, from the time point of view, it is impossible for the three of them to commit the crime." Qin Siwei said, "You said yesterday that it was just a trick. What's going on?" "Actually, you should have heard of this trick." I typed a line of keywords on the computer and forwarded the search results to him. "Phone fraud...criminals pretending to be the police..." Qin Siwei stared at the computer screen, "I know this case. There have been dozens of cases since the end of last year. We have been investigating and have uncovered two criminal gangs."

"Then you should know how they pretended to be the police to commit fraud?" "I know, they use a network information platform, which is a network communication software similar to three-way calling, to disguise the calls made by their mobile phones, and the numbers displayed on the other party's phones are their preset numbers. They put their own The phone is disguised as the switchboard of the Public Security Bureau..." Qin Siwei gasped as he spoke, "Oh my God! You mean someone used similar software to call me and disguised his mobile phone number as Chen Xuefang's landline number! "

"Yes, to put it bluntly, it's not worth mentioning." I took a sip of coffee, "But there is a loophole in this network communication software. If you call back immediately after hanging up the other party's call, you will get a reply that the line is busy. Yesterday That's how you got the call from Chen Xuefang's house." "I foolishly gave others an alibi." Qin Siwei gritted his teeth and said, "So Yang Jianmei, Li He and Liu Yang are all possible?" "No, only one person is possible." I reminded him, "The fake phone number is dialed through network software, which requires the cooperation of a computer and a mobile phone. Yang Jianmei was with us at the time, and she didn't have a computer at hand. Liu Yang came by taxi. I don’t have a computer with me. Therefore, the only person who can call you is Li He, who drives his own car and has a laptop. I think he used the wireless network to call you in the parking lot, and then Walked a few minutes to the bar. And he invited you to Jin Yu's memorial service in order to use you as his own alibi."

"Li He?" Qin Siwei was skeptical, "He planned all of this? But what is his motive?" "Li He and Chen Xuefang have a good personal relationship. He himself admits this, and Yang Jianmei also mentioned it. And he also participated in the project with problematic accounts. What do you think is his motivation?" I asked Qin Siwei back. "He was Chen Xuefang's accomplice? He was afraid that the embezzlement of public funds would be revealed, so he killed Chen Xuefang to silence him and blamed her for all the problems." Qin Siwei pondered for a few seconds.Suddenly, his face darkened, "That's not right. It is reasonable for Li He to kill Chen Xuefang to silence him, but why did he kill Jin Yu? Jin Yu is his best friend. And, how did he do it? There were three Be alone with him!"

I smiled and said, "I didn't say that Jin Yu was poisoned to death by Li He." "It's not Li He?" He seemed to be dazed by my words, "You mean, the two cases were not committed by the same person? Then why did Jin Yu's medicine bottle appear at Chen Xuefang's house? These two murders... " "When did I say it was two murders?" I tilted my head and looked at his misty expression. Qin Siwei stared at me blankly, his jaw almost dropped to the ground.I reached out and waved in front of his eyes: "Hey, are you okay?" He grabbed my hand, his eyes were still a little dull: "What do you mean?"

"Think about it, you have confirmed that Jin Yu once prescribed a large amount of nalatamine from the hospital; you have confirmed that he has been hit for various reasons recently and has the motive of suicide; At the time of the death, all those involved have conclusive alibi; moreover, you have confirmed that no one has sneaked into the celebrity garden." I took a deep breath, "We were wrong from the beginning. Jin Yu is not Murdered, he simply committed suicide." "Suicide?" Qin Siwei shook his head firmly, "Impossible, what happened to the poisoned wine in the glass and the disappearing medicine bottle?" "That's just an elaborate deception." I patted his hand, "Think about it again, there is a big difference between the glass of red wine found at Jin Yu's house and the drug concentration in his body, what does that mean? It means that Jin Yu was not poisoned to death by that glass of red wine. Some people want to mislead the police's judgment and point Jin Yu's death to murder." "You mean, Li He?" Qin Siwei began to understand, "When he returned to Celebrity Garden to pick up the car the next day, he found that Jin Yu was dead, so he disguised the scene... No, why did he do that?" "On the one hand, it is to frame Chen Xuefang and give Chen Xuefang a more reasonable reason to commit suicide." I said, "It is not a day or two since Li He premeditated Chen Xuefang's death. I guess he has heard the rumor that the institute is auditing. However, it is not easy to get rid of Chen Xuefang and protect himself. He must have painstakingly worked hard. It was a coincidence that he found Jin Yu's body, but he immediately thought that this was an excellent opportunity-disguised the scene as a murder, Then put the blame on Chen Xuefang. In this way, Chen Xuefang's suicide in fear of crime becomes logical. On the other hand, even if the police find out that Chen Xuefang was murdered, considering her relationship with Jin Yu and the cause of death of the two people, you will Think that these are two murders committed by the same murderer. Li He has no motive for murdering Jin Yu, let alone the time to commit the crime, so it is difficult to suspect him." "So, he took the remaining half bottle of medicine, and threw a few more pills into Jin Yu's unfinished red wine before leaving." Qin Siwei nodded, "Then he started planning to kill Chen Xuefang, and even thought of using I made an alibi for myself. Yesterday at the bar, he insisted that Jin Yu couldn’t commit suicide, and he led me to the place of murder.” "It was his performance yesterday that aroused my suspicion." I told him, "Both Yang Jianmei and Liu Yang believed that Jin Yu committed suicide. Only Li He was singing the opposite tune, but the Jin Yu he described, who was relentlessly striving for his ideals, was really different from ours. Many of Jin Yu’s behaviors that I know are very different. I think Yang Jianmei’s description of Jin Yu is the most accurate. He kept silent about breaking up with Chen Xuefang, and it can be seen that this person's habit is to avoid. Like an ostrich, he deceives himself and others." "Since when did you become a psychologist?" "I just think that everything Yang Jianmei described is more in line with a child who was rejected by his parents, abused by his grandmother, and then lived under the fence for many years, and Liu Yang's views are basically the same as hers. In contrast, Li He's opinion of Jin The description of Yu is somewhat misleading." "So you think he's lying." "As a friend who grew up together, he shouldn't have such a big deviation in his understanding of Jin Yu. Therefore, he is deliberately misleading you and wants you to believe that Jin Yu was murdered." Qin Siwei stopped talking. He lowered his head and thought for a while, then said doubtfully, "But, with just a silent phone call, there is no way to convict Li He." "As evidence, I prepared one for you. He said that he hadn't contacted Chen Xuefang in the past few days, but at around nine o'clock yesterday morning, his car appeared on the street near Chen Xuefang's house." "His car? How did you know?" Qin Siwei was even more surprised, "The community where Chen Xuefang lives requires registration for vehicles entering and leaving, but there is no Li He's car in the registration book." "My Captain Qin!" I said helplessly, "He's going to kill Chen Xuefang, how could he leave a record in a grand manner? But judging from the time, it's impossible for him to go home to pick up the car after killing Chen Xuefang, and then He arrived at Shichahai around 10:10. Therefore, he must have parked his car on the street outside the community, and he didn’t expect that there was a surveillance camera at the intersection of that street.” "Oh, so that's why you came to Wang Zili." Qin Siwei finally understood, "Did you find out Li He's entry and exit records yesterday morning?" "Found it, he arrived at Chen Xuefang's house around 9:20 yesterday morning, and left at about 9:45." I turned off the computer, "But he can deny it based on this alone. You still have to Check Chen Xuefang's belongings and Li He's belongings that day, there should be more clues." "How would I live without you?" Qin Siwei smirked and twisted my face, I punched him, he stepped aside, grabbed the briefcase and ran out the door.
