Zheng Kai put aside the photo of Lu Dafu's death. There is no doubt that Han Jian killed Lu Dafu.
It was the man in black trench coat who killed Lu Guoqiang and Lu Wen.
"Did you find anything?" Su Lan asked. Zheng Kai didn't look back: "It must have something to do with the tranquilizer." Su Lan stopped eating.
At this moment, Su Qing also came over. The two women stood on the left and right sides of Zheng Kai respectively. Su Lan said, "Please elaborate."
"When was the first time we dealt with tranquilizers?" Zheng Kai asked. Su Lan and Su Qing looked at each other: "It was at the vegetable market when Watson committed suicide." Zheng Kai nodded.
Watson's suicide points everything to tranquilizers. But it's a pity that so long has passed.
Professionals have not made very good progress in analyzing the ingredients and efficacy of tranquilizers. In other words, the police station only knew that Watson died from a tranquilizer.
We also roughly know the cause of Watson's death. But there is no way to analyze the ingredients and other medicinal effects of the tranquilizer.
"When Watson committed suicide with a tranquilizer, were there any other people at the scene who saw it?" Zheng Kai didn't pay much attention to the situation at that time. Su Lan and Su Qing probably didn't pay much attention either. At this moment, people who were still eating breakfast on the side The colleague wiped his mouth with his sleeve: "Yes, even though the evacuation was done at the time, there were still some onlookers who saw Watson committing suicide. In addition to the onlookers, there were also some who lived in high-rise buildings near the vegetable market. Residents also said that they saw the whole process of Watson's suicide." Zheng Kai had long found photos of Watson's suicide scene from the archives and put them on the table: "This is the biggest problem, Watson's suicide The process was seen by too many people, and many people talked about it, so the sedatives must have been leaked out, and the one who is most interested in sedatives is Zhiwang Technology."
"You mean, the problem lies with Intelligent Network Technology?" Su Qing took over. Zheng Kai shook his head. Some words could be guessed in his mind, but the nature would be different when spoken.
"Although I don't know where Watson found the tranquilizer, it is obviously impossible to know the whereabouts of the tranquilizer from a dead man's mouth, so Lu Dafu's death became the second key point." Zheng Kai took over the photos of Lu Dafu's death. It can be clearly seen in the photos that a large dose of tranquilizers entered Lu Dafu's body.
Lu Dafu is dead. Moreover, he died of sedatives. Because of this, if you want to know the whereabouts of the tranquilizer, you only need to find the murderer of Lu Dafu.
That is to find Han Jian.
"Did anyone watch the scene of Lu Dafu's death or see what was going on in the room?" Zheng Kai asked again.
Su Lan and Su Qing also didn't know. They were not the first police officers to arrive on the scene. Soon, a young man came out from a group of colleagues: "I was the first group of people to arrive at the scene of Lu Dafu's death. Except for the people who called the police, no other people saw the scene of Lu Dafu's death." What the colleague said He said it very firmly, and Zheng Kai naturally believed what his colleagues said.
At this moment, another colleague said: "Actually, it was other people who saw the death scene. Didn't Lu Dafu's three family members go in and see the death scene?" Strictly speaking, the family members of the deceased are also considered members of the public.
Originally, family members were not eligible to enter the murder scene. But with the permission of Su Qing and Zheng Kai, Lu Guoqiang, Lu Wen and Jiang Min were qualified to take a look.
A word that wakes up the dreamer! Zheng Kai's thoughts suddenly cleared up. That's right! Apart from the police at the police station, the only people who had seen Lu Dafu's death were the people who called the police and three people from the Lu family.
Zheng Kai's brain was spinning rapidly. It was probably one of the three people who entered the murder scene, Lu Guoqiang, Lu Wen, and Jiang Min, who told Zhiwang Technology about Lu Dafu's death. Zhiwang Technology found out that Lu Dafu died from a tranquilizer, and the suspicion was once again ignited. Tranquilizer cravings.
As long as the murderer of Lu Dafu is caught, he can know where the last batch of tranquilizers produced that year is.
But it's a pity. Han Jian is also dead. And he committed suicide in the same way in front of Zheng Kai and Su Qing.
Han Jian's death showed that Lu Dafu's case could be closed. The police announced that the murderer who killed Lu Dafu committed suicide in fear of crime and announced that the case was closed.
Watson is dead. The tranquilizer trail was broken. Han Jian is dead. The clue to the tranquilizer was broken again. Two consecutive losses should have made some people within Zhiwang Technology angry and determined to find the whereabouts of the tranquilizer. Therefore, the people most likely to know the whereabouts of the tranquilizer are Lu Guoqiang, Lu Wen and Jiang Min.
Because Han Jian once sent packages to all three of them. And the man in the black trench coat should be the killer sent by Zhiwang Technology.
Suddenly, Zheng Kai realized a problem. That is, Zhiwang Technology does not know where the last batch of tranquilizers produced that year are.
At that time, the batch of sedatives was marked as being sent to the mental hospital in Nanhai City. However, Zhiwang Technology probably went to the mental hospital in Nanhai City to search for the remaining sedatives, but did not find any remaining sedatives.
Apparently, someone had hidden the tranquilizer. It might be Han Jian who hid it, or it might be someone else.
Interestingly, Zhiwang Technology is actually looking for tranquilizers. With the strength of their company, it should be a very simple matter to mass-produce tranquilizers.
What's more, Zhiwang Technology also has improved tranquilizers. There is absolutely no need for the sedatives used more than 20 years ago!
Seeing that Zheng Kai didn't speak for a long time, Su Qing couldn't help but shake Zheng Kai's shoulders: "What are you thinking about? Do you want to be so lost in thought?" Zheng Kai came back to his senses.
Maybe the logic is straightened out. Only a few minor issues remain. For example, what role did Pombo play in the whole process?
Since Lu Wen and Pang Bo are so close, in theory, the man in the black trench coat should not let Pang Bo go in order to find out the whereabouts of the tranquilizer.
But the strange thing is that Pombo did not die. He is alive and well. The man in the black trench coat had plenty of chances to kill Pang Bo. After all, Pang Bo was not surrounded by plainclothes policemen to protect him at all times.
On the contrary, it was Jiang Min. Under the premise of being quietly followed and protected by plainclothes police, the man in the black trench coat took great risks and took action against Jiang Min, sparing Pang Bo, who had a greater chance.
unreasonable. Very unreasonable.
"The murderer may attack Pang Bo next." Zheng Kai said softly. Su Lan and Su Qing's expressions became serious.
No more deaths! The current impact is bad enough. If another person dies, there is no telling what serious consequences it will have.
