Serious Crime Unit 1

Chapter 1063
"Of course it can be dissolved in water. Oxycodone can be taken orally, injected, or administered in the large intestine. If someone gives him the drug, it should be taken orally and then absorbed into the gastrointestinal tract."

"Does oral medicine work quickly?" Jiang Yiming lacked knowledge of medicine, while Luo Jin was simply an encyclopedia of medicine.

"It begins to take effect in half an hour and reaches its peak in one to two hours."

"When is the approximate time of Zhen Xing's death?"

“2021年4月12日凌晨2点半到4点半之间。”

"Do you think Zhen Xing committed suicide?"

"Correct."

"But Lao Wu and Xiao Ke found the oxycodone medicine bottle on Zhenxing's bedside table. It was empty and all the medicine had been consumed. Zhenxing's fingerprints were found on the medicine bottle, but there were no other people's fingerprints. From this point It looks like Zhenxing has taken all the medicine in the medicine bottle."

"This can be forged. The murderer can wait until Zhenxing is unconscious or dead and put his fingerprints on the medicine bottle. We will find out if Zhenxing took the medicine after we investigate, because each bottle of medicine has The flow is recorded in the medical system.”

"I agree with you." Lu Yingying walked in at this time, and Jiang Yiming said to her, "The autopsy results are out. Zhenxing died of respiratory failure due to taking a large amount of oxycodone. This is a murder case. There is one thing I don't understand. , Zhenxing’s bedroom access control uses facial recognition, so how did the murderer enter the crime scene?”

Lu Yingying thought for a while and replied: "I think first of all, we should consider that Zhenxing brought the murderer into the scene; secondly, the murderer has hacking skills and cracked the access control. Xiao Huihui and Gao Shupeng from Baidu Security Lab took less than 10 seconds , using a printed photo to unlock a mobile phone under a certain lighting environment. Theoretically, as long as a clear photo of the owner of the mobile phone is taken, the phone can be unlocked."

"Is it so easy? Face-based access control is not as safe as a key."

"No, face-based access control is more than ten times more secure than keys, because keys are easy to make, but it is very difficult to forge faces."

Jiang Yiming nodded and said: "Yingying, go and notify everyone of the meeting. We are going to formally file a case. This may be a clever murder case. The murderer seems to be an invisible man. We must gather everyone's wisdom and use a hundredfold energy to detect it. The murderer must not be allowed to commit suicide like Qin Yayan."

After a while, everyone sat together for a meeting. Jiang Yiming explained the situation, and Luo Jin also explained the autopsy process and results in detail. After comprehensive analysis, he believed that this was a clever murder case, and everyone agreed to open the case for investigation.

"I extracted several pieces of tissue paper from the trash can in Zhenxing's bedroom, and there was semen on them. Judging from the color of the semen, it should have been left by the deceased within 12 hours. He may have had sex with someone within a few hours of his death. We had sex. Female secretions should still be extracted from the tissue paper. I have handed the tissue paper to Dong Dawei for disposal," Wu Jiang said.

Xiao Ke continued: "I also extracted a fresh set of fingerprints from Zhenxing's bed frame. After analysis, the fingerprints belong to a woman. I think this woman may be the person who had a relationship with Zhenxing. She is highly suspicious. . It's a pity that this woman's shoe prints were not found on the carpet in the bedroom. They must have been destroyed by Su Weilu and the others."

"This woman is very suspicious and we have to find her."

"It should be easier to find this woman. First, you can find it through the driving recorder of Zhenxing Porsche; second, you can find it through traffic surveillance video. The road dedicated to Youjiao Villa is called Youjiao Road, which borders Laishan Road and becomes It is in the shape of a cross, with Youjiao Villa on the left and Laishan Villa on the right, and there is a monitor at the border." Lu Yingying said.

"We also need to investigate Su Weilu, Gu Jiacai and Fan Li. After all, there are only their shoe prints at the scene."

"Okay, let's do this. Yingying and Xiaorou go to check the surveillance video on the road. Lao Wu and Xiaoke go to ask Zhenxing's wife Liang Ying'er to see who has a grudge against Zhenxing. Zhou Ting and I go to find out where the mysterious woman comes from. Where. Everyone will report the investigation results in a timely manner." Jiang Yiming assigned the tasks.

After Lu Yingying and Wen Xiaorou walked out of the conference room, they went to check the surveillance video of Laishan Road. After Lu Yingying entered the password, she entered the traffic surveillance system and started to watch the surveillance video of the intersection of Youjiao Road and Laishan Road.Wen Xiaorou started watching at 4 o'clock in the evening on April 11, because Gu Jiacai said that he went to bed around 10 o'clock that night, and Zhen Xing did not go back before 10 o'clock.

Lu Yingying started watching at 12 o'clock on the 0th, and then looked back. She judged that Zhenxing should have returned to Youjiao Villa after 0 o'clock.Because Zhenxing likes to live overnight, and that day is Sunday, under normal circumstances, he will not go back before 0 o'clock that night.

As expected, Lu Yingying saw Zhen Xing's Porsche driving into the screen at 12:01 in the morning on the 10th. She pressed the pause button, brought her eyes close to the screen, looked carefully, and found that the person driving the car was not Zhen Xing. There was no one in the car, probably Zhenxing was sitting in the back seat.But I can't see what's going on in the back seat.

She believes that the driver may be a professional driver or a substitute driver.She clicked the play button and the video continued to play. Ten minutes later, the driver rode an electric scooter into the scene. She pressed the pause button again and saw the license plate of the electric scooter, but because the light was not bright enough, the license plate was blurry.

She took a screenshot of the picture and processed it with software. The screenshot became clear, and she could see the license plate number: long A1452P, which is the city's electric vehicle number.Lu Yingying was a little excited.She entered the password again and entered the vehicle registration system. She soon found out that the driver's name was Ouyang Xuan, a 22-year-old farmer from the suburbs, and his mobile phone number was recorded on it.Lu Yingying immediately called Jiang Yiming, explained the situation, and sent Ouyang Xuan's mobile phone number to Jiang Yiming's mobile phone.Jiang Yiming and Zhou Ting were on their way to Youjiao Villa. He admired Lu Yingying's efficiency very much. He asked Zhou Ting to park the car on the side of the road while he called Ouyang Xuan.

After Ouyang Xuan met Jiang Yiming, he accepted Jiang Yiming's inquiry.He said: Around 4:12 in the morning on April 12, he saw Zhenxing coming out of the World Trade Hotel. After shaking hands with two friends and saying goodbye, he approached him and asked if he wanted someone to drive for him?Zhen Xing said yes.So, Shinyuki handed him the car keys and drove to the parking lot.

After the car arrived, he opened the rear door, let Zhenxing and a beautiful girl sit in, closed the door, and then returned to the driver's seat to drive.After he drove the car to Youjiao Villa, he parked the car. Zhenxing took out his mobile phone, scanned his WeChat payment QR code with WeChat, and paid him 100 yuan. Then he rode his electric bike back to the entrance of the World Trade Hotel. Continue to drum up business.

"Do you know that lady?" Jiang Yiming asked.

"I don't know him, but I have met Mr. Zhen. He often goes to Huaya Revolving Bar." His voice was low, slightly hoarse, and rough.

"Do you think that lady works at Huaya Revolving Bar?"

"It should be. She has such a good figure and a pretty face. She must be a bartender at the bar."

"What were they talking about in the car?"

"They were all disgusting words. Most of them were spoken by the young lady. She tried hard to please Mr. Zhen, but Mr. Zhen seemed to be tired or had too much to drink. He didn't respond to her actively. She didn't find it boring either. She was still trying her best to talk. nice words……"

"Did they talk about anything in particular?"

"Probably not. I was concentrating on driving and didn't pay attention to their conversation." He apologized to Jiang Yiming.

"It's okay. Thank you for your cooperation. You can go now." Jiang Yiming patted him on the shoulder to express his gratitude.He shook hands with Jiang Yiming and walked away.

Jiang Yiming and Zhou Ting took the elevator to the Huaya Revolving Bar. It was evening. The door of the bar was open, but there was no one inside.The hall is neatly arranged with sofas and many high stools. The decoration is luxurious and bright, and the huge round wine cabinet is filled with various kinds of wine.

Zhou Ting shouted: "Is there anyone? Is there anyone?"

The door of a private room opened, and a young woman walked out with a cigarette in her mouth. Although she was old, she was still pretty. She was wearing heavy makeup, sleek and worldly. She walked up to them and said: "Two Gods, Our bar doesn't open until 8pm, so you guys are early."

"I'm sorry, we are from the criminal police team of the city bureau. We are not here to spend money, but to handle cases." Zhou Ting took out his police officer ID card and handed it to her, then continued, "Are you the person in charge here?"

"Oh, I'm sorry! I'm sorry! I'm An Lin, the account manager here. How can I help you?" Her originally indifferent face instantly turned into a smile. After smiling, she added, "Let's sit down and talk. Standing is hard." As he said this, he walked to the sofa and asked them to sit down.

Jiang Yiming pulled out Zhenxing's photo from the gallery on his phone and handed it to her. She took the phone and looked at it and said, "I know this person. He is Mr. Zhen. He is a frequent visitor to our place. He is generous, generous and generous. We They all like him."

"He is dead. We are here to investigate this case. Around 4:12 in the middle of the night on April 12th, did he bring a young lady back from you?"

"This..." She hesitated, not knowing whether she should tell the truth.

"Don't hide the facts. You will be held legally responsible for lying. We have already investigated, that's why we came to the door."

"Well, yes, he took Ye Qianqian away around 12:[-] in the morning that day. But, we don't know where they went and what they were doing? After get off work, we can't control the lady."
