Zheng Kai is actually looking forward to Wang Chong's ability to imagine real objects in the world of strange objects. Maybe, this ability would allow Wang Chong to survive easily in the world of strange things.
After confessing to Wang Chong, Zheng Kai did not return to his dormitory, but ran towards the police station. Originally, Zheng Kai asked for leave today and did not need to go to work.
But Zheng Kai had something to check. When they arrived at the police station, many colleagues were a little surprised to see Zheng Kai. After saying hello, Zheng Kai came to the archives room.
"The Starving Ghost said that the businessman who died unjustly died not long ago. As long as it was not a normal death, the corresponding file information should be found in the archives, unless the businessman is not from the northwest district of Zhi'an City." Zheng Kai turned over all the cases from the past year.
Among them, leaving aside those minor cases that did not result in human life, there were almost more than 300 cases in which people died.
On average, one murder occurs every day. Zheng Kai carefully browsed the information on these cases, and after excluding some of the cases in which the murderers confessed and closed the cases frankly, there were only less than fifty cases left in his hands.
After a long time, Zheng Kai rubbed his eyes: "It's not easy to find." Although there are less than fifty murder cases within the scope, there is no evidence for all the convicted murderers in these cases, and some even have no candidates for the convicted murderers. None, just possible suspects.
Without knowing whether they were the murderers, these suspects were under tremendous pressure from public opinion. As many as 32 of them could not bear the pressure and chose to commit suicide.
Before they died, these people who committed suicide were all saying that they were wronged. Of course, there is no way to prove these words.
Just as there is no way to prove that they are murderers, there is also no way to prove that they are innocent. At this moment, there was a knock on the door of the archives room.
Zheng Kai looked up and saw that Su Lan and Su Qing came to the archives together.
"Didn't you ask for leave?" Su Lan asked curiously. Su Qing naturally sat next to Zheng Kai and looked at the case files that Zheng Kai was reviewing: "Why are you looking at these cases?" Zheng Kai sorted out the cases in his hands and replied with a smile: "Stay at home. It's boring, anyway, Gu Youde's court trial is over, and I wasn't too affected, so I just wanted to come to work normally." Su Lan lowered his head and looked at the file in Zheng Kai's hand.
Su Lan's acumen as a police officer allowed Su Lan to discover at a glance that these cases occurred very recently, and almost all of them were murders that occurred within a year: "Are you very interested in these cases?"
"No, I'm just sorting out the latest case information." Zheng Kai put the file aside. Su Qing didn't think too much.
But Su Lan looked suspicious: "You didn't lie to me, did you?" I don't know why, but after being in contact with Zheng Kai for a long time, Su Lan always felt that Zheng Kai's behavior was very purposeful, and it didn't look like he was doing it casually. .
Zheng Kai looked innocent: "I never lie to people."...This sentence is actually a lie.
But Zheng Kai didn’t tell anyone, and no one knew. Zheng Kai changed the topic: "Captain Su, don't you want to rest in the hospital for a while? It's not good to run around with injuries on your body." Su Lan teased in an interesting way: "Are you caring about me? Or are you taking it seriously? You care about me in front of my sister." Zheng Kai: ... Su Qing rolled her eyes at Su Lan.
Seeing this, Su Lan stopped chatting and became serious: "We have almost finished investigating the case of mass suicide. The murderer is the man who kidnapped me in the vegetable market. His name is Watson, a native of Zhi'an City. At present, we can only find out that he is a psychiatrist, has lived in many places, and moved frequently, and more information has not been found yet." Zheng Kai nodded.
Watson took the blame for the painter. But Watson is an accomplice. Although he only helped the painter hypnotize these living people, he was also responsible for the death of these living people.
After so many years of mass suicide cases, hundreds of people have died. Even if Watson does not commit suicide, the death penalty awaits him.
"Where's the autopsy report?" Zheng Kai asked curiously. Su Lan knew that Zheng would ask about this in a meeting, so she handed the information in her hand to Zheng Kai: "The drug Watson injected into his body before his death was actually the most common tranquilizer. This kind of tranquilizer can be found in many places. You can buy it, but the main manufacturer is Zhiwang Technology." After Zhiwang Technology officially changed its name from Qiu Shi Pharmaceutical, it weakened the production scale of the drug to a certain extent and instead invested more funds in research and development. So now it is not easy to get drugs produced by Zhiwang Technology.
Many drugs are produced by different manufacturers, but are sold under the authorized name of Zhiwang Technology.
The tranquilizer that Watson injected into his body was a very pure drug produced by the original manufacturer of Zhiwang Technology. In this regard, you can find the anti-counterfeiting QR code of Zhiwang Technology and the specific production number on the syringe.
Zheng Kai briefly opened the autopsy report. Basically no abnormalities! Watson is in good health.
At least before the injection of sedatives, Watson's physical characteristics were abnormally healthy, and it could even be said that health was a bit exaggerated.
Watson has no interest in exercising. Almost all the muscles on his body are naturally grown, but the density and relaxation of these muscles are much higher than those of normal people. This is also the reason why Watson can hold Su Lan hostage and can compete with Su Lan in terms of strength.
"Taurine and dopamine in his brain were secreted in large amounts before death, which also caused his state to be abnormally excited before death." Su Lan was afraid that Zheng Kai wouldn't understand the technical terms above, so he kept Explaining to Zheng Kai.
Zheng Kai rubbed his chin and asked a very crucial question: "Then he injected himself with a sedative before he died to suppress his excitement?"
"It's possible, but the effect is just the opposite." Su Lan pointed to the last column of the autopsy report, where it was written that the secretion of taurine suddenly increased, while dopamine, which manages happiness, dropped significantly.
The drop in dopamine indicates that Watson's mood before his death, although exciting, was without any trace of happiness.
The sudden increase in taurine causes abnormal excitement in the nervous system. Originally, the role of tranquilizers was to inhibit the secretion of these components.
But it seems that tranquilizers accelerate the secretion of taurine. Zheng Kai fell into deep thought while looking at the autopsy report. Su Lan did not disturb Zheng Kai. Now she gradually felt that Mr. Ren Xin's words were correct. Maybe it was the right decision to listen to Zheng Kai's opinions on some matters.
An idea flashed in Zheng Kai's mind! The opportunity he had been waiting for had come!
