Zhang Chao was relatively confident in the handling of the scene at that time. He handled the scene very cleanly. The key is that he did not stay at the scene for long.
From the moment he entered Wang Hong's house and had a conflict with Wang Lili and strangled her to death, the whole process only took about ten minutes.
Just for these ten minutes, Zhang Chao stayed in that home for several hours, just to clean up all traces of himself.
In fact, Zhang Chao was very anxious for a day or two after killing the person. He was afraid that the police would find him, and that he would leave some traces of himself that had not been wiped clean, leaving fingerprints or footprints, etc., including his own. hair.
But after two or three days, he found that there was no trouble, no one contacted him, no one asked him, and even the police didn’t even call him, so he felt that the matter might be settled. .
After all, he put Wang Lili directly in the suitcase and took her away, and he faked the disappearance of Wang Lili.
A disappearance case is not necessarily a homicide case. Any situation where a person goes missing can happen, and it does not necessarily mean that the person is dead.
And another thing about Zhang Chao that made him more certain that he had no major problems was that he had not had much contact with Wang Lili.
The two people didn't even have each other's phone numbers, and he had only met each other twice.
As for his relationship with Wang Hong, in fact, the two of them only chatted ambiguously a few times. They had the idea that they wanted to have sex, but they didn't actually have much contact with each other.
In addition, there was no surveillance outside or inside the community, and the security boss at the door was confused. Therefore, no one should have discovered his actions that night.
Over the past few years, Zhang Chao has either committed crimes or is on the road to committing crimes. Anyway, he has not done anything serious. Money is not all about the right way, so he is very aware of some of the usual methods used by the police to investigate.
No matter what the case is, the investigation starts with the victim’s interpersonal relationships. As long as there is no specific evidence at the scene, the interpersonal relationships are sorted out step by step.
Neither I nor Wang Hong nor Wang Lili have close interpersonal relationships, so the police found me and it was just a routine interrogation.
If you confess, then the police case will be solved, and the only thing left behind is to find evidence.
But if he doesn't explain, the police will really just doubt the policeman he seemed to be leading just now. There is no evidence that what he said deliberately in front of him was to scare him, so it is not impossible to make him speak.
Zhang Chao knows very well that the police love to play tricks like this.
But what if the other party really has evidence? What if what the police said is true, the other party really extracted it from the mop rod and kitchen knife handle. When it comes to the so-called own cells, are you really exposed?
Zhang Chao is not a policeman after all.
He has done a lot of dealings with the police when doing these thieves, and he also checked some information on the Internet. But for the real criminal investigation system, let alone him, even ordinary police officers are not very clear about it. There are twists and turns and some technical details.
So he felt particularly ridiculous about extracting his own cells from mop rods and kitchen knife handles, and then locking the DNA information. How could it be possible?
So Zhang Chao is now undecided whether to confess frankly or to resist and be strict.
As for Zhang Chao's situation, Wang Zhaokai was clear about it.
When he was drinking tea just now, he was actually drinking tea. He had been busy for a whole day and didn't even drink a sip of water. As for Zhang Chao's interrogation, Wang Zhaokai actually didn't care.
When Zhang Chao was arrested, he knew that this guy was a veteran. When he saw him being interrogated just now, his eyes kept evading.
Looking at this, it seems that he often interacts with the police. He is full of little thoughts. What is it? What can I say? I can't say anything. I can jump and pick up things. He said that this is what these guys are like. He will tell you whatever the police find, and he will just look at the evidence in the hands of the police.
This is why Lu Chuan did not arrest Zhang Chao immediately after discovering Zhang Chao's actions. The main reason was that he was afraid that this would happen to him.
No explanation was given. As a result, the police had no substantive evidence, so they had to let him go in the end.
If there is no substantial evidence in front of Lu Chuan, Wang Zhaokai may be anxious to think of other ways to see if he can pry open Zhang Chao's mouth.
But it doesn't matter now.
Because Lu Chuan has already made it clear that there is irrefutable evidence of the relevant DNA information of the murderer. In this case, just by comparing this evidence with Zhang Chao's blood, he can determine whether the other party is the murderer.
Although judging from the current police analysis, judging from various circumstances, and logically speaking, this Zhang Chao is the murderer.
But the police ultimately need to talk about evidence to solve a case, and they also need to talk about evidence during trial. If there is no evidence and only rely on confessions, the case will not be settled or dead.
As for what Wang Zhaokai just told him about leniency for those who confess and those who resist severity, it actually has an impact on the death penalty, but the impact is very small.
Wang Zhaokai hoped that Zhang Chao would better not say anything.
He didn't say anything. As long as the comparison of the DNA information is completed, he can do whatever he wants. The case can be solved with zero confession.
On the contrary, if Zhang Chao really confessed calmly and honestly, it would be really difficult to handle later. After all, as an interrogator, all of Zhang Chao's performance during the interrogation would be difficult to deal with. They must truthfully record whether there are mitigating circumstances for confession, and this must be recorded in detail.
Of course, if the DNA information comparison is unsuccessful, it means that they have indeed arrested the wrong person.
However, judging from Wang Zhaokai's experience, this situation basically does not exist. The DNA information comparison must be successful. There is definitely something wrong with Zhang Chao.
Of course, taking a step back, even if Zhang Chao really has nothing to do with this case, Zhang Chao can't escape. After all, he asked his younger brother to take the blame for the robbery he committed three years ago.
His younger brother accused him of being a criminal. The sentence for the crime of shielding might not be long. Three years later, the other party had already served his sentence for the crime of shielding, so he might have been released directly.
But Zhang Chao can't do it. He himself committed the crime of robbery, so he should go in and serve his sentence again.
Of course, there may be some other details that need to be discussed in this case, and it is possible that the responsibilities of some people still need to be held accountable.
Because in terms of cause and effect, if Zhang Chao had indeed gone to prison to serve his sentence and had not committed the crime, would it have been impossible for the other party to do so? Or is it simply impossible to kill Wang Lili and commit this crime? (End of chapter)
