Serious Crime Unit 1

Chapter 862 The Mystery of Suicide (8)
"Okay, I'll give you my phone so you can check it all." Ai Qiusheng took out his phone, unlocked it with his fingerprint, and then handed it to Jiang Yiming.Jiang Yiming first checked his WeChat payment record and found nothing suspicious. Then he checked his Alipay and soon found that he used Alipay to buy two bottles of Alprazolam at Ganwei Yao.com.

This discovery made Jiang Yiming secretly happy, and Ai Qiusheng's tail was finally exposed: "Look, you bought two bottles of Alprazolam from the Wechat Drug Network, how do you explain it?"

"Wan Yiran asked me to help buy it. Her dosage of medicine was increased and she had to take 9 tablets of alprazolam a day, but the doctor only allowed her to take two tablets a day. She was afraid of trouble, so she entrusted me to buy it online. Isn't this a crime?" He was secretly proud, this was the best answer, because Wan Yiran was dead and could not be verified.

Jiang Yiming knew that there was no point in getting entangled with him. Only by finding ironclad evidence to prove his crime could he be convinced and the case turned into an ironclad case.

But how can we find evidence to prove that Ai Qiusheng murdered Wan Yiran?Wan Yiran was murdered. There is no doubt about this. The murderer is most likely Ai Qiusheng, but Ai Qiusheng is too cunning to find out his flaws.

Everyone sat down for a meeting to discuss how to find evidence of Ai Qiusheng's murder.

"We assume that Ai Qiusheng waited for Wan Yiran to fall into a deep sleep and then used a syringe to inject liquid sleeping pills into Wan Yiran's body through the vein. Then, he would definitely leave a needle hole on Wan Yiran's hand, and then find the syringe through the needle hole. , and then find the buyer through the syringe, because the syringe has a serial number." Luo Jin said.

"The autopsy report of the forensic doctor Che Fengshan of the Jiangbei District Criminal Police Team did not mention that Wan Yiran had needle holes in her body. Did he miss the test?" Xiao Ke asked.

"It is very possible that the examination was missed, because during the autopsy, the corpse spots on Wan Yiran's body had not receded. The pinhole was so small that it could easily be covered up by the corpse spots." Luo Jin answered.

"Even if we find the eye of the needle, it's useless. If Ai Qiusheng takes the syringe away, we have no way to find evidence to prove his crime, because there is no syringe in Ouyang Jun's on-site investigation evidence."

"This Ai Qiusheng is really cunning, and he does it flawlessly."

"Roca's law tells us: As long as a criminal suspect enters the scene, he will definitely take something away and leave something behind. That is to say, there will be trace evidence left at the scene. Don't be discouraged, continue to use your brains and think about how to do it. Get evidence." Jiang Yiming comforted everyone.

"What I'm most worried about is: Ai Qiusheng crushed alprazolam into powder, mixed it with a lot of honey, washed it with boiling water, tricked Wan Yiran into taking it, and then took the cup away and threw it away so that we can't find it. There's evidence." Zhou Ting said worriedly.

"When the case reaches a deadlock, returning to the scene for investigation is the best way. Because Ouyang Jun and his colleagues are not as experienced as us and their technical skills are not as sophisticated as ours, so I think we must re-investigate the scene." Wu Jiang said.

Jiang Yiming agreed with Wu Jiang's idea and asked Luo Jin to check Wan Yiran's body again to see if there were needle holes and other injuries.

Just after the meeting, Ai Qiusheng came to Jiang Yiming. Jiang Yiming asked him to go to the office to talk. Ai Qiusheng followed Jiang Yiming to the office. After the two parties sat down, Jiang Yiming asked: "What do you want to see me for?"

"I'm here to clear my suspicions. Today I opened my email and found a video that Wan Yiran sent me before she committed suicide. In the video, she told me that she was tired of life and was going to heaven to rest. Please don't be sad. " He took out his mobile phone, called up a video from the gallery, clicked to play it, and handed the mobile phone to Jiang Yiming.

Jiang Yiming took his mobile phone and looked at it. He saw Wan Yiran sitting on the bedside wearing a white floral pajamas. Her hair was fluffy and she was listless. She faced the camera and said, "Teacher Ai, I'm really tired. Let me tell you frankly." You, if I can't be with you in this life, I would rather die. Death is not terrible at all. When I was 17 years old, I went into shock. I woke up five hours after being rescued by doctors. I don't remember feeling any pain at all during the shock. So, death is really not scary.”

She blinked her eyes, then took a deep breath, closed her eyes gently, opened her eyes after a while and continued: "I consider myself beautiful, gentle and talented, and I am 10 years younger than Yang Li. Why am I here?" I can't replace her in your heart? I am obedient to you, worship you like a god, and protect you like a son. I have had two abortions for you, and I have paid so much, why do you just Doesn’t it impress you?”

At this point, her tears fell down like broken pearls, and then she raised her right hand to wipe the tears. After wiping them, she continued: "Do you remember our first time? At that time, I participated in the provincial landscape painting competition. I felt Your paintings will definitely win awards, at least the third prize. You think so too. However, the reality is very cruel. I didn’t even get the Excellence Award. My self-confidence was completely shattered. Then you came to me. There were people around me who kept encouraging and comforting me, saying that after a few more years of practice, I would definitely stand out. You said a lot, a lot. My heart was melted by you, and I fell into your arms unknowingly..."

She stopped, brushed back the hair that fell in front of her eyes, then raised her head and continued: "From then on, I feel that I am an extremely happy girl. As long as you are there, it is my paradise. It is your love that inspires me to move forward." Trek, I vowed to work hard to learn painting skills to repay your love. From then on, I only had you and painting in my eyes. After a year of hard work, I finally gained market recognition and became a leader in the Provincial Academy of Fine Arts. Being able to support myself through painting is all thanks to your teaching and care for me."

She sighed deeply: "But you can make me or destroy me. I asked you to divorce Yang Li and then marry me. You agreed, but as the days passed, you left your vows behind. Even when you are with me, you have to keep it strictly confidential, like a thief. You said that if our affairs are known to the school, your status and reputation will disappear, or even be ruined. Of course, I dare not go against your words, because I put you I didn't even tell my best friend Fan Lingling." At this point, she looked sideways at the window, thought for a while and then said: "I'm really too tired, I don't want to be in the boundless darkness. Struggle, I don’t want to live such a sneaky life, then the only way is to leave this world forever. I have hesitated about suicide countless times, but today, I finally made up my mind to go to heaven. Maybe there is no deception and lies in heaven... Goodbye, my dear Teacher Ai, I hope we meet again in the next life. At that time, you will be an unmarried handsome young man and I will be an unmarried young girl."

After she finished speaking, she picked up a bottle of medicine from the bed on the right and said, "There are 100 tablets of alprazolam in here. I want to take them all so that I don't have any worries." After that, she unscrewed Bottle cap, pour all the pills into the palm of your hand, then put it into your mouth, lift the cup on the bedside table, pour water into your mouth, tilt your neck, swallow the pills and say: "Goodbye..."

Then she burst out laughing and turned off the video recorder, where the video ended.

"Captain Jiang, I'm sorry, it was me who harmed her. I really shouldn't have had an extramarital affair with one of my students. I want to apologize to her parents." Ai Qiusheng said sadly.

"Please send this video to my mobile phone. We will check this video to see if it is fake."

"Forgery? How is it possible? Can her voice and person be faked?" Ai Qiusheng found it incredible.

"The people and voices may be real, but I want to see the date of filming. May I ask why you didn't let me see this footage until today?"

"It was sent to my email on the day Wan Yiran committed suicide, that is, at 3:31 pm on March 14. I rarely use email. I didn't see it until I opened my email today, so I sent the video to my email." On the mobile phone, I brought it to you to see. This video is enough to prove that Wan Yiran committed suicide."

"Okay, you go back first. We will make our own judgment on whether Wan Yiran committed suicide or was murdered."

After Ai Qiusheng left, he went to find Wen Xiaorou and sent the video that Ai Qiusheng sent him to her computer, asking her to check it to see if it was fake.

After Wen Xiaorou received the video, she right-clicked the properties of the video and checked the detailed information. She saw that the shooting date was indeed 2019:3 on March 31, 14. The total length of the video was 15 minutes and 10 seconds. It was shot with an Apple phone. In other words, after Wan Yiran took the video, she sent it to Ai Qiusheng's email.

"Is the video real?" Jiang Yiming asked.

"The video is real, and the date is real, but the date can be modified, and you can also set up an automatic email on your Apple phone. This doesn't mean anything. The most important thing is that the video is not forged. Therefore, Wan Yiran most likely committed suicide. of."

“Have all our efforts been in vain?”

"There is currently no evidence to prove that Wan Yiran committed suicide."

At this time, Lu Yingying came in. Wen Xiaorou asked Lu Yingying to watch the video together. Lu Yingying pulled a chair and sat down in front of the computer. She began to carefully check the video to see if she could see any flaws. After watching it several times, Lu Yingying thought for a while. Said: "I'm just afraid that the video was not taken on the afternoon of March 3, because the date can be modified and any time can be set. However, the lighting of the video is very good. I don't know if it is a lighting problem."

"If Wan Yiran turned on all the lights in the room before she died in order to capture the video clearly, would it be possible to have this effect?"

"Correct."
