If we just looked at the whereabouts of Ke Zuo and Zou Qian that night, it would be impossible for them to complete the series of murders and burials.
But if you look at the behavior of the two people together, it's a different story!
Ke Zuo had three minutes of blank time, and no one knew what he was doing.
In these three minutes, he could kill a person with cyanide, but he could not complete a series of burying the body.
Although Zou Qian had sufficient alibi when Guo Taiming was killed, he had sufficient time to bury the body.
So if Ke Zuo killed Guo Taiming first, then Zou Qian would bury the body.
Then it all makes sense!
But now all this is just Han Cheng's inference. Without conclusive evidence, if he rushes to interrogate Ke Zuo and Zou Qian, it will be counterproductive and alarm the snake.
Han Cheng decided to start with the cyanide that caused Guo Taiming's death.
Cyanide is a highly toxic chemical that is strictly controlled in the Dragon Kingdom.
However, for a top physics student like Ke Zuo, it is not difficult to make cyanide by yourself.
Although it is not difficult to make cyanide, cyanide is a highly toxic substance after all, and it is easy to cause accidents if it is accidentally inhaled into the body.
Therefore, making cyanide must be done in a ventilated and open place.
As long as Ke Zuo's base for making cyanide is found, he and Guo Taiming's death will be inseparable.
Han Cheng decided to follow Ke Zuo and find out the experimental base for making cyanide.
After Han Cheng and the others closely followed Ke Zuo for 24 hours, they finally found the small factory that Ke Zuo rented as a laboratory in the suburbs to make cyanide.
When Han Cheng and the others rushed into the factory with live ammunition and guns raised, in addition to Ke Zuo, Zou Qian, Lu Shi, and Sun Mo were also in the factory.
They were preparing to destroy the experimental equipment inside and destroy the evidence.
"Stop!" Han Cheng pointed his gun at Ke Zuo and shouted.
Others also pointed guns at Zou Qian, Yu and the other three.
Seeing the black hole of guns pointed at them, the four of them stopped.
Ke Zuo raised his head and looked at Han Cheng, pretending to be calm and said: "Officer Han, why are you here?"
"Ke Zuo, if we can find this place, you should understand what's going on without me having to say more! You are so smart!" Han Cheng smiled.
"Okay! I plead guilty. I did all this and it has nothing to do with them. I will go with you and you let them go!" Ke Zuo was making his final struggle.
He wants to bear all the crimes alone!
It seems that the relationship between him and Zou Qian is quite deep.
But how could Han Cheng believe what Ke Zuo said so easily.
"Ke Zuo, do you really think you can complete this series of murders and burials by yourself?! This should be the stockings gift box that Lu Shi finally gave to Guo Taiming! There must be cyanide left in the stockings inside! "
Han Cheng picked up a gift box that Ke Zuo and the others had not had time to destroy.
This gift box was exactly the same as the gift box containing stockings found in Guo Taiming's bedroom closet.
Although Han Cheng had always felt that Ke Zuo was related to Guo Taiming's death, he had always been a little confused as to how Ke Zuo poisoned Guo Taiming with cyanide during the three minutes he disappeared.
Because a cautious businessman like Guo Taiming would not let Ke Zuojin harm him personally.
It wasn't until Han Cheng saw the gift box that Ke Zuo and the others had not had time to destroy that he figured out the problem.
At the same time, he also figured out the entire process of Sun Mo, Lu Shi, Ke Zuo, and Zou Qian conspiring to kill Guo Taiming.
Han Cheng concluded that the four people committed crimes like this.
The first person to appear on the night of the incident was Sun Mo, who tried his best to get Gong Yue to spend the night at his place.
The purpose is twofold.
One is to distract Gong Yue and leave Guo Taiming alone at home, so that they can implement the subsequent murder plan.
One is to create an alibi for yourself.
That night, he deliberately used a pinhole camera to record a video of him and Gong Yue spending the whole night together, so that when the police investigated him in the future, he could escape without arousing suspicion.
The last time, when Han Cheng and Fu Yong went to ask him, he deliberately opened the secretly filmed video of him and Gong Yue doing that kind of thing on his computer.
The purpose was to attract Han Cheng's attention, make Han Cheng pay attention to the video that night, and then eliminate his suspicion of committing the crime.
Sun Mo’s move can be said to be truly brilliant!
Even Han Cheng was deceived by him!
After Sun Mo sent Gong Yue away, Lu Shi appeared next.
That night, she tried her best in the live broadcast room, wildly teasing and teasing the male viewers, including Guo Taiming, the top brother on the list.
Then Guo Taiming wanted to buy Lu Shi's original stockings as usual!
So, Lu Shi delivered poisonous stockings stained with a large amount of cyanide to Guo Taiming's doorstep.
After Guo Taiming brought the box containing the poisonous stockings into the house, he would definitely open the box, pick up the stockings, and smell them vigorously. As soon as he smelled the cyanide, he would inhale the cyanide into his body, and he would soon die.
After Guo Taiming was poisoned, Ke Zuo was next to appear.
He first tampered with the circuits on the 36th floor of the Kaixuan Building, causing a power outage on the entire floor. Then he lied about going to repair the electricity and went to the 36th floor. Then he opened the door of Guo Taiming's house by his own method, and then put Guo Taiming's body and The gift box containing the poisonous stockings was moved to a hidden place, such as the refuge floor.
Then he quickly repaired the electricity and continued to check the building's circuits with his partner Xue Jiang to create his own alibi.
The last person to appear was Zou Qian.
She deliberately chose to go to work at ten o'clock in the evening. At this time, Guo Taiming was already dead, and even if the police investigated her, she would have sufficient alibi.
In order to bury Guo Taiming's body without being discovered by his colleague Li Hui.
Zou Qian deliberately let Li Hui rest while she went to clean the 36th to 40th floors alone.
In fact, her purpose was to use this time gap to go to the refuge floor on the 37th floor to bury Guo Taiming's body.
The cooperation between the four of them can be said to be "flawless" and "impeccable"!
Their plan was almost perfect, killing people and escaping unscathed.
These are Han Cheng's speculations on the murder process of Guo Taiming by the four people from Ke and Zuo!
Although it is speculation, it is supported by various evidences.
For example, Han Cheng and the others detected the fingerprints of Guo Taiming, Lu Shi, and Ke Zuo from the box containing the poisonous stockings.
The footprints of Ke Zuo and Zou Qian were found in the stairwell from the 36th to 37th floors.
Zou Qian's hair and Ke Zuo's clothing scraps were also found on Guo Taiming's body.
...........
In the face of various evidences, Ke Zuo, Sun Mo, Zou Qian, and Lu Shi finally confessed.
The crime process confessed by the four people is almost completely consistent with Han Cheng's inference.
But why did these four young men in their prime conspire to kill a well-known entrepreneur?
It's a long story!
