Early the next morning, Xie Zhihang, the captain of the Second Brigade of the Criminal Investigation Detachment, came to Chen Weibin's office and said: "Detachment Chen, when our Second Brigade went to Zhou Yuanliang's company to understand the situation yesterday, I heard from people in the company that Zhou Yuanliang's driver Zhao Xiaojiang had not seen anyone all day and had not asked for leave. ”

"That's weird!" Chen Weibin replied.

As Zhou Yuanliang's full-time driver, his boss was poisoned, at this juncture, if this case has nothing to do with him, according to common sense, he will not disappear out of thin air to show his innocence, but at this time, he avoided it, isn't it "no silver three hundred taels here"? It will definitely arouse the high suspicion of the public security organs! Even if people don't show up, the phone should at least be unblocked. Chen Weibin analyzed the driver's abnormal behavior and basically judged that the driver Zhao Xiaojiang had a certain relationship with the case.

Chen Weibin immediately picked up the phone on the table and dialed Tao Chunqiang's mobile phone: "Tao Bureau, we visited Zhou Yuanliang's company employees and found that Zhou Yuanliang's driver, Zhao Xiaojiang, disappeared after Zhou Yuanliang's death, and we suspect that he has a major connection with this case." In accordance with the provisions on technical investigation in the "Provisions on the Procedures for the Handling of Criminal Cases by Public Security Organs", we believe that Zhao Xiaojiang can be implemented. Asked the Tao Bureau to coordinate and carry out a technical investigation of Zhao Xiaojiang. ”

Tao Chunqiang was silent on the phone for a few seconds, and said: "Your suspicions are justified, this Zhao Xiaojiang's behavior is indeed very abnormal. In this way, I will report the situation to Director Fei and enlist the support of the technical investigation department. ”

The case seems to have a slight brow, and so far, at least one clue can be pursued. So, after Zhou Yuanliang's death, where did Zhou Yuanliang's driver Zhao Xiaojiang go?

Thinking of this, Chen Weibin immediately dialed the mobile phone of Li Jun, the captain of the three major teams: "Li Jun, have you extracted the surveillance video around Zhou Yuanliang's villa?" ”

Li Jun replied: "Detachment Chen, the surveillance video has been obtained, we have extracted the video of the month before Zhou Yuanliang's death, and it has been copied to the hard disk, we will return to the detachment immediately." ”

Li Jun rushed back to the detachment with three teams of police, and Chen Weibin and Yuan Qing were already waiting in the conference room. Zhang Peng, the internal staff, immediately turned on the projector and plugged the hard drive that Li Jun brought back into the computer.

Li Jun said: "When we were extracting the video, we found that there was just a camera facing the gate of Zhou Yuanliang's villa, so we could watch the video first. ”

"Good! Then play it first, and start playing it from the first night of Zhou Yuanliang's death. Chen Weibin said to Zhang Peng.

Zhang Peng let out a "hmm" and began to play the video.

"How many surveillance footage footage was extracted this time?" Chen Weibin asked Li Jun while watching the video.

"A total of five shots, all of which are installed near the door of Zhou Yuanliang's villa." Li Jun replied.

"Five? Less! If you still want to extract, your three teams will go to check the surveillance footage near Zhou Yuanliang's house, including the footage installed outdoors at the door of the surrounding residential buildings, government agencies and companies, and we must ensure that we do not miss any suspicious points. Chen Weibin said.

"Okay. Do it right away. Li Jun replied.

At this moment, Lei Ming, the forensic doctor of the detachment, walked into the conference room and said, "Report, we have made new discoveries through further examination of Zhou Yuanliang's body. ”

"Tell me about it." Chen Weibin said.

"We tested the muscles inside the pinholes in the deceased's abdomen, from which we found king cobra venom. At the same time, we also found snake venom in the residue of the deceased's stomach, and the deceased suffered from a stomach ulcer before he died. Therefore, we came to the conclusion that the snake venom that caused Zhou Yuanliang's death entered the bloodstream through two ways: injection and stomach blood vessels. ”

"Then ......" Chen Weibin frowned and asked, "What kind of way caused the death?" ”

"This ...... Not sure! Lei Ming shook his head, and continued, "King cobra venom is highly venomous, and any one of them is enough to kill the dead. The deceased either ingested food or water containing snake venom into the stomach and then injected the snake venom. Either that, they were injected with snake venom and then ingested food or water containing snake venom. It is also possible ...... Both ways are done at the same time. Based on the technical means we currently have, it is really difficult to judge which way caused the death! ”

Chen Weibin nodded and said to Lei Ming: "You go and get busy." ”

"Yes." Thunder left the conference room.

Chen Weibin turned his head and asked Yuan Qing: "Have the people from the first and second teams come back?" Did you find Zhou Yuanliang's remaining insulin? ”

Yuan Qing replied: "I haven't come back yet, I guess I'm still looking for it." ”

"Hurry up!" Chen Weibin said to Yuan Qing.

The video screen was playing on the big screen, and Chen Weibin said to Zhang Peng: "Speed up the playback speed and increase it to twice the speed." ”

The video time entered 0:30 on the day of Zhou Yuanliang's death, and Zhou Yuanliang's car appeared, which was a hatchback Mercedes-Benz off-road vehicle. The Mercedes-Benz car drove into the big iron gate of Zhou Yuanliang's villa, stopped at the door, and saw the driver Zhao Xiaojiang get out of the car first, walked to the right rear door of the car, opened the door, and Zhou Yuanliang got out of the car. When the two walked to the door, Zhou Yuanliang opened the password door lock, and Zhao Xiaojiang and Zhou Yuanliang entered the room together. Three minutes later, Zhao Xiaojiang walked out of the room, got back into the car, and drove the car into the garage. Then, Zhao Xiaojiang walked out of the big iron gate, stood outside the big iron gate for two minutes, came a car, picked up Zhao Xiaojiang and left.

Seeing this, Chen Weibin said: "Stop the video! The three teams immediately contacted the traffic police department to find the vehicle that picked up Zhao Xiaojiang at that time, found the owner of the car, and brought people to the detachment to assist in the investigation. At the same time, mobilize the surveillance cameras of the whole city to find the trajectory of Zhou Yuanliang's Mercedes-Benz that night, remember, don't let go of every station, we must fully grasp all the people Zhou Yuanliang came into contact with that night, and all the places he walked. In addition, Yuan detachment, you check Zhao Xiaojiang's home address, and immediately take someone to his house to find it. ”

Yuan Qing said "um" and went out with someone.

The surveillance cameras in the public areas of Miojiang City have been installed in the past two years, and they are all high-definition, and the license plate number of Zhao Xiaojiang's car is very clear in the surveillance video, and through the cooperation of the traffic police department, Li Jun quickly found the owner of the car and obtained the mobile phone number of the owner. Li Jun immediately got in touch with the owner of the car and asked the owner to come to the criminal investigation detachment immediately.

The owner of the car was named "Wu Chao", sitting in the interrogation room of the criminal investigation detachment, Wu Chao looked frightened.

Chen Weibin asked Wu Chao: "What is the relationship between you and Zhao Xiaojiang?" ”

Wu Chao's hands and feet began to tremble, and he replied in a low voice: "Zhao Xiaojiang? I don't know this person. Comrade policeman, am I guilty of a traffic violation? That's also the traffic police team, why did you call me to the criminal investigation team? I didn't do anything bad! ”

Chen Weibin asked again: "At 0:35 the day before yesterday, you didn't know the person you picked up in the Banjiang villa area?" ”

Wu Chao thought for a while and replied, "Early the day before yesterday? Oh, I picked up a guest at Banjiang Villa, but I didn't know him. ”

Chen Weibin observed Wu Chao's expression and asked, "Guest?" What guests? ”

Wu Chao replied: "I'm just an online car-hailing person, the online car-hailing car called by that person, I went to pick him up, but I really don't know him." After Wu Chao finished speaking, he took out his mobile phone, flipped out the order record at that time, and handed it to Chen Weibin.

Wu Chao looked at Chen Weibin and continued: "Comrade policeman, this is the record of that day, you can take a look, I dare not deceive you!" ”

Chen Weibin carefully checked Wu Chao's order record and said, "Don't be nervous, we just understand the situation." You recall, where did that person get off the car? ”

Wu Chao replied: "I remember this, he got off the car at the gate of the Zhulin Community." The bamboo forest community is not far from the villa with the river, and there is no traffic jam at night, about 5 minutes to arrive. ”

At this moment, Yuan Qing called Chen Weibin: "Chen detachment, we are at Zhao Xiaojiang's house in the bamboo forest community at this time, I heard his wife say that Zhao Xiaojiang has not been home for the past few days, and the phone can't get through, I don't know where he went?" People in their family are also looking for him. ”

Chen Weibin hung up the phone, Wu Chao said that Zhao Xiaojiang's drop-off location coincided with Zhao Xiaojiang's home address, it seems that what Wu Chao said should be the truth.

Chen Weibin said to Wu Chao: "Okay. Thank you for your cooperation! You can go, and we will contact you again if there is any situation. ”

Wu Chao replied, "I will definitely cooperate with your investigation." After speaking, he left the criminal investigation detachment.
