The person must have caught the right one, there is no problem with that.
In the interrogation room, Wang Biao looked stunned when facing the DNA identification and analysis report.
Wang Biao’s first reaction was this, how is it possible?
Five years have passed since the incident, not to mention that when he did it, he did it very covertly and left no clues at all.
But now the DNA found in the lime plaster actually matches my own, which is simply ridiculous.
"Wang Biao, tell me, how did Zhang Mengyao die? Why did you kill her back then? Why did you seal her in a stone sculpture and send her back to the experimental primary school?"
This case is actually in the process of being solved, although There are few clues, but many doubts.
First, judging from the results of the current investigation, there are no clues in Zhang Mengyao’s interpersonal relationships that she knew Wang Biao.
In other words, if the police had been following the instructions beforehand. If the investigation idea is determined and the investigation is centered on Zhang Mengyao's interpersonal relationships, Wang Biao will not be traced at all.
Because the two people don’t know each other at all.
A teacher at an experimental primary school and a car wash owner had no intersection with each other at all, and he didn't buy a car when Zhang Mengyao disappeared.
Besides, Wang Biao didn’t drive a car at that time, so how did these two people meet?
Another doubt is why after killing Zhang Mengyao, the murderer sealed his body in a sculpture and placed it in the experimental primary school.
This has puzzled all the investigators.
And how this statue got into the school has not been found out yet.
The surveillance system was long gone five years ago, so I still don’t know how it was transported in, who purchased it, and who approved it.
Judging from the expenditures on the experimental primary school’s books, there were no approval procedures or expenditures to purchase the statue, which means that the statue suddenly appeared in the experimental primary school.
This is a problem. How did Wang Biao transport this statue to the school without arousing anyone's suspicion?
So the police initially judged that the possibility that the perpetrator was Zhang Mengyao’s colleague was very high.
But what was found during the current investigation was that the case was done by an unrelated person like Wang Biao.
Faced with irrefutable evidence, Wang Biao was unable to refute it.
Zhang Hui personally conducted the interrogation.
"Wang Biao, this report is the first identification analysis of the skin scraps found in the lime powder of the statue of the deceased Zhang Mengyao."
With conclusive evidence, there is no It was necessary to go around in circles with the other party, so Zhang Hui threw the report directly in front of Wang Biao during the interrogation.
“Explain, why is your skin tissue in the plaster wrapping Zhang Mengyao’s body?”
explain?
Wang Biao was dejected and explained nonsense.
Is there any explanation for this? He killed the person, but what Wang Biao didn't expect was that the current police were so powerful.
I was very careful when handling the corpses, and they were all sealed in plaster statues. Wang Biao was a little confused as to how the other party found them.
“How did you find out?”
Wang Biao has done this kind of work not once or twice, he is very experienced, and there is something he can't figure out is that this statue should be in the experimental primary school.
Then Wang Biao said: "This statue should be in the Experimental Primary School. Even if you find the statue, you should move it away carefully. As long as you don't break it, you won't be able to find the body inside."
Statue, who would break this thing if nothing happens? As soon as Wang Biao's words came out, Zhang Hui finally breathed a sigh of relief.
Although Wang Biao’s skin tissue has been found in the powder of the statue, if the other party does not have a reasonable explanation and statement, then he is the murderer. This conclusion is beyond doubt .
But I am afraid that the other party will really have some reasonable explanation. For example, if he sells this raw material, then it is possible that his skin tissue will be integrated into the plaster statue.
Fortunately, this situation does not exist. Wang Biao's words prove that he is indeed the murderer.
"When the old campus of the Experimental Primary School was being renovated, the workers accidentally knocked the statue over when moving it. After it broke, the body inside was exposed."
There is nothing to hide about this.
Zhang Hui told the truth.
Wang Biao nodded suddenly, that's it.
"Okay, tell me, why did you kill Zhang Mengyao? Judging from the results of our current investigation, you and the deceased should not have known each other. Since there was no intersection, why did you kill her again? ?”
There must be a motive for killing.
Before arresting Wang Biao, Zhang Hui and the others had already investigated the other party's information in detail.
Although he has a criminal record, this person has still opened a car wash business honestly in the past few years. It seems that the business is not bad and he has made some money. Now the other party's economic conditions are better and he has bought a house. Got the car.
But why did the other party want to kill? He and Zhang Mengyao had no interaction and did not know each other at all, so there was no motive for the murder.
Was it really a robbery? Or rape, or some other reason?
But if these were the reasons, why did Wang Biao seal the body inside the statue and send her back to the experimental primary school? So a lot of things here don't make sense.
What matters in solving a case and convicting is the entire criminal chain, the evidence is complete, and the motive is clear.
But now there is a DNA identification report that has designated Wang Biao. He was the murderer, but why did the other person kill and how did he kill him? Why did he seal the body in a statue and send it back to the experimental elementary school. Then he had to figure out how he sent this statue to the experimental primary school.
"Can I have a cigarette?"
Zhang Hui nodded and personally lit a cigarette on the table for the other party.
During the interrogation of a criminal suspect, if the other party wants to smoke, there is a high probability that the other party is going to confess. This is a good sign.
Sure enough, Wang Biao started to explain after taking two puffs of cigarette.
"Whether you believe it or not, I did not kill anyone. I did not kill this person."
Didn't you kill him?
Zhang Hui was stunned.
He thought that Wang Biao was going to explain a series of things like how and why he killed, but in the end, he came up with an explanation that he was not the murderer.
"You didn't kill the person. Why is there your skin in the statue that wrapped the body?"
Wang Biao then said: "It's simple, because I handled the body."
Corpse?
"You disposed of the body?"
Zhang Hui knew that this simple sentence contained too much information.
Since Wang Biao is the one who disposed of the corpse, who is the murderer? Who is the murderer? Why did he help dispose of the body? (End of this chapter)
