After returning to the special case team, Guan Xin showed Shen Zezhi the printed text messages and call records of Zhao Shangda. Text messages are simple, all one or two sentences.

"I'm in Pingjing City."

"I didn't find anyone surnamed Liu, so I found a hotel for the time being."

"He answered my phone and said to give me money in a few days, and I would stay for a few more days."

"Boss Liu asked me to meet, and he promised to give me money. I'm going to get the money tonight and I'll be home tomorrow. ”

It was the last day of text messages, after which Zhao Shangda disappeared. Shen Zezhi looked at the call records of Chen Yu and Zhao Shangda, after the text message that day, Chen Yu called Zhao Shangda, but he didn't answer once. In other words, this text message is the last message left by Zhao Shangda.

Ji Ziyue finished reading it and said: "Zhao Shangda's disappearance must have something to do with this Boss Liu." According to the text message, Boss Liu made an appointment with Zhao Shangda and gave him payment. After that, Zhao Shangda disappeared. ”

Shen Zezhi said: "That's right, we have to find a way to find this Boss Liu now." ”

At this time, Sang Yunqing suddenly came in, she was still wearing a white coat, and it seemed that she was in a hurry. She handed a file bag to Shen Zezhi: "Team leader, this is the file you gave me, I carefully looked at those photos and the autopsy report at that time, and I found bad news." ”

Yesterday, Shen Zezhi took the file bag and told everyone that he only showed it to Sang Yunqing. Although everyone didn't know what file Sang Yunqing was talking about, they also felt the seriousness of the matter when they saw his expression.

Sang Yunqing said: "The woman in the file is in similar physical condition to Zhao Shangda, but her mental tolerance is far inferior to Zhao Shangda. The side effects of the antipsychotic drugs used on her were also much greater than they are now. So, my conclusion is that their drug trials have made a lot of progress. ”

Shen Zezhi sealed the contents of the file to others, and he said: "This is what I let Yun Qing see, and it is also another victim in our case." Her body was found three years ago, and an autopsy later revealed that she may have died from a drug trial. But since her identity could not be determined, the case was put on hold. Now there is another victim, and the Minister means to join the investigation. ”

Shen Zezhi said and turned around and asked Guan Xin: "Did the Zhao Shangda family you check yesterday have any mental illness history found?" ”

Guan Xin said: "Zhao Shangda has no mental illness, and his family has no history of mental illness. ”

Qi Kai said: "If they are studying antipsychotic drugs, then why should they find a person who is not mentally ill to study?" ”

Sang Yunqing said: "People who are not mentally ill can also get mentally ill. And this kind of half-Ruth's psychosis will be more serious than the family's inherited condition, but it is easier to cure. ”

Kiko said in disbelief: "You mean, after they catch normal people, they first turn them into psychosis, and then use their medicine to try to cure him." ”

Sang Yunqing nodded: "What a bunch of crazy people." ”

Ji Ziyue frowned and said, "Then how did they choose the test subjects?" If you don't want to be discovered, it's obviously safer to choose that kind of homeless person. But they chose Zhao Shangda, he has a wife, children and a career, isn't it too risky to let such a person be an experimental subject? ”

Qi Kai also said: "That's right, they definitely don't want to be discovered by others in such an experiment, the more secretive the better." Zhao Shangda is definitely not a good test subject. ”

Shen Zezhi thought for a while and said, "What if they don't know Zhao Shangda's true identity?" ”

Noriko suddenly realized: "Team leader, you mean that the person who conducts the drug test and the person who prepares the test are separated. They do not know the origin of these test items. ”

Shen Zezhi said: "It is very likely that if Boss Liu, who Zhao Shangda contacted, has a connection with this organization or he himself is a member of this organization, then Zhao Shangda is likely to be handed over to them as a test subject as a homeless man." ”

Ji Ziyue said: "I don't know how long they have been conducting this experiment and how many test specimens they have caught." ”

Shen Zezhi said: "Qi Kai and Teacher Zhao must find Boss Liu, Ziyue and I continue to investigate Yan Ruofei, he must have found something." ”

Shen Zezhi thought for a while and said, "Guan Xin, you pay attention to the news of the homeless people, especially those in Pingjing City. They need people to do experiments, and they always have to show clues. ”

Ji Ziyue said: "To do drug research, you must need a group of drug experts, their test direction is antipsychotic drugs, and there must be people who must have psychiatric experts." We can check it out from the expert pool. ”

Shen Zezhi said: "Okay." Everyone went their separate ways. ”

Ji Ziyue and Shen Zezhi got into the car, and Ji Ziyue looked at him and asked, "Where are we going?" ”

Shen Zezhi said while starting the car: "Let's go to the place where Zhao Shangda was found." If our speculations are correct, the place where Zhao Shangda escaped must have something to do with the place where he tested the drug. ”

Ji Ziyue nodded: "Zhao Shangda's health is very bad, he can't walk for a long time, so he is most likely to escape in a car." He paused here and said: "Is there such a possibility, they thought that Zhao Shangda was dead and were going to dispose of his body, but Zhao Shangda was not dead, he woke up halfway and escaped." ”

Shen Zezhi nodded: "It's also possible, if that's the case, then that industrial park and maybe that's where they dispose of the corpse." This kind of corpse must not be disposed of casually. Otherwise, it is easy to be discovered. ”

Because the industrial park is on the outskirts of the city, it was already three hours later when their car arrived. Noriko went to the management office to find out what companies were in the industrial park. Shen Zezhi went to check the place where Zhao Shangda was discovered alone.

It's still the same place, and even the cordon has been removed. The temperature is very low today, Shen Zezhi is wearing a black coat, he is standing in the middle of the road with his hands in his pockets and looking around. If those people thought that Zhao Shangda was dead, then they would use a car to pull Zhao Shangda's body here to deal with it. The car stopped not far from here, but this was not the place to dispose of the body. The people in the car got out of the car to run errands, and no one would worry about a corpse. So Zhao Shangda was left alone in the car. At this time, Zhao Shangda woke up. He struggled out of the car. He was in terrible physical condition, so he stumbled to a trash can not far from the car, and he hid behind the trash can. The people who dealt with Zhao Shangda came back after finishing their errands and found that Zhao Shangda was missing, and they would definitely be shocked. The street lights in the park are very dim, and they are still far away from each other, so they will become a blind spot. And these garbage cans are right in the middle of two street lights.

The person who lost Zhao Shangda must have been panicked, so they didn't find Zhao Shangda hiding behind the trash can. They searched for a while and then left, because there were security guards in the park, and they were worried that they would run into them.

That's right, security!

Shen Zezhi was going to go to the management room to ask the security guard on duty that night, and it was very likely that he had seen the car.

When Shen Zezhi arrived at the management room, Ji Ziyue had just finished asking. Shen Zezhi asked the security guards on duty that night. The administrator rummaged through the log book and found the man.

"Xiao Wang, Wang Gang." Administrator said.

Shen Zezhi said: "We want to talk to him." ”

The administrator picked up the walkie-talkie and called Wang Gang, and soon Shen Zezhi and Ji Ziyue saw the security guard Xiao Wang.

Seeing Shen Zezhi and their Wang Gang looked very nervous, he was just eighteen years old this year and came from the countryside to work. He was suddenly informed that two policemen were looking for him, which startled him.

The more Kiko saw that he was nervous, she smiled and comforted him: "You don't have to be too nervous, we just want to ask you a few questions, just tell you the truth." ”

"I'll tell the truth, tell the truth." Wang Gang said.

Shen Zezhi asked him: "You were on duty on the night of December 3rd, right?" ”

Wang Gang nodded: "It's me." ”

Shen Zezhi asked: "Did you find a strange car entering the park that night?" ”

Wang Gang shook his head: "There shouldn't be." ”

Shen Zezhi said: "Are you sure?" ”

Wang Gang said: "This ...... I didn't see anything strange when I was on patrol

Cart. They are all cars that come to the park often. ”

Shen Zezhi asked again: "All the cars entering the park will pass through Changxing Road, right?" ”

Wang Gang said: "Yes." ”
