Dong Jun was very calm when being questioned by the police.
Like other neighbors, they showed emotions such as nervousness, fear, and curiosity.
But when he heard the police discussing in the corridor that Qin Weiwei was killed and did not die naturally, his heart stopped.
Dong Jun could not believe that the murder method he had planned for three years was discovered by the police in just a few minutes.
At that time, he was almost scared to death.
In fact, there are serious cognitive barriers between different professions.
For example, Lu Chuan and others couldn't figure out how Dong Jun was able to kill people in a secret room.
Dong Jun also didn’t know that the changes in a person’s body after death would tell the police a lot of useful information.
Although people are dead, their bodies can still talk.
Actually, Dong Jun was very cautious and careful in what he did.
Even with Lu Chuan's spot investigation skills, he didn't find many valuable clues at the scene.
But he should never move the body after Qin Weiwei's death.
The grid marks imprinted on the restroom floor tiles on the back of the corpse gave everything away.
From this, Lu Chuan became suspicious.
Next, we will focus on investigating the bathroom.
Thus, the words written by Dong Jun on the mirror were discovered.
Wang Zhaokai answered Dong Jun's question: "Qin Weiwei's first death scene was in the bathroom."
"Qin Weiwei fell on her back after death, so her back was printed on the bathroom floor tiles The grid traces.”
“Although you move the body, this grid will not disappear. As time goes by, the grid traces will become clearer and clearer.”
"Since someone has touched the body, it means that someone must have been present at the scene after Qin Weiwei's death."
"What's going on?"
Dong Jun understood.
If he had not been interested in it at that time and had not done what happened next...
There would have been nothing.
Maybe this is how things really happened.
In fact, if Dong Jun had not moved the body at that time, the case might have just gone away.
The entire scene was sealed, the door was locked, and the windows were locked. The cause of death of the deceased was cerebral hemorrhage.
There is also a corresponding history of encephalitis in the hospital.
Everything makes sense.
But there are no ifs in everything.
Dong Jun thought he had done a perfect job, but it foreshadowed his arrest.
"Dong Jun, how did you leave the scene and lock the door after the violence?"
"This..."
"It's actually very simple... …”
Among all the steps to kill, making a secret room at the scene is the easiest in Dong Jun’s opinion.
The door lock at Qin Weiwei's home is an ordinary mechanical lock without an automatic device. If you want to unlock it, just turn the unlock button inside.
Dong Jun tied a live rope buckle on the anti-lock button.
“The old-fashioned anti-theft door is not very airtight. Take the rope out from the side, then lock the door, pull it hard, and the lock will be on.”
“Because I can tie it. It is a live rope buckle. The untied thread of the live rope is on the outside. The buckle is untied by tugging hard, and then the rope is removed. The door is locked without anyone noticing. "
Motive of murder. Dong Jun explained clearly the murder process and how to form the secret room.
At this point, the case has been successfully solved.
First squadron office.
"Brother Wang, I checked the death of Dong Jun's child, and it seems..."
Everything about Dong Jun's killing of Qin Weiwei stemmed from the accident 5 years ago. .
At that time, after Dong Jun’s child died, someone raised the issue of Qin Weiwei’s refusal to save him.
But in fact, Qin Weiwei's friends said that they were taking pictures at that time. Really didn't notice the kid.
“After Dong Jun’s child died, his wife divorced him.”
Wang Zhaokai also checked the situation that year, and Dong Jun also Quite miserable.
That year, his son died, his wife got divorced, he was defrauded during the renovation, and he owed more than one million yuan for the project.
Just like Dong Jun said, he almost jumped off the building.
“Actually, I think Dong Jun has to be blamed for this matter. His child was so young. He threw the child away and left. Who can he blame if something goes wrong?”
< br>"I think he failed to fulfill his most basic guardianship obligations back then."
"Don't say that Qin Weiwei and the others didn't notice the child when they took pictures, even if they did, they had no obligation to save the child. "
"Dong Jun just made an excuse for himself."
"You can't say that. Dong Jun is the biological father of the child. It would be more difficult for the child to lose him than anyone else."
"Besides, who cared about us when we were children? If we didn't run around outside every day, nothing would happen. Ah.”
Let’s chat, everyone has different opinions.
In fact, we can’t say who is right or wrong about what happened five years ago.
But it was really wrong for Dong Jun to blame Qin Weiwei for his son's death.
Moreover, this guy is also a ruthless person.
Three years!
I have been a neighbor for three years, and I help with everything big and small, just to build a closer relationship.
Then plan to kill.
There may be something wrong with Dong Jun’s mentality.
There was a breakthrough in the case. After Lu Chuan learned about the situation, he immediately reported to the branch.
Although the secret room created by Dong Jun was very simple, it was something he couldn't imagine when he didn't expect it.
It was also the first time for Lu Chuan to come into contact with this type of case.
The remaining work is relatively simple, which is to organize the case information.
Lu Chuan had followed up on the entire process of compiling all the case information on the previous murder case, so he was already quite familiar with it.
It’s also easy to conduct reviews.
Of course, the turmoil in the case has not subsided yet.
Lu Chuan heard that all the residents in the community where the crime occurred had recently changed their door locks.
There are also some rumors on the Internet.
But as time goes by, it will subside sooner or later.
Everyone in the criminal police brigade can finally go home and have a good sleep.
For this case, 100 people from the criminal police brigade were busy for three days without stopping for a moment.
Like Lu Chuan and several squadron leaders, they can basically only sleep three or four hours a day.
Now that the case is finally solved, there is no need to work overtime.
Tomorrow morning, Dong Jun will be forced to identify the scene, and then he can be handed over to the detention center.
After the specific trial is held and the trial is held on a certain day, the person can be sent to prison.
However, Lu Chuan estimated that Dong Jun would not be able to stay in prison for more than a few days.
His situation is basically a death sentence.
The probability of death with reprieve is very small.
After all, it took three years of planning. It can be said that the will to kill is extremely strong, the subjective will is extremely bad, and there is an act of insulting the corpse after the murder.
A week has passed since all this work was done.
But before Lu Chuan could rest for a few days, the Criminal Police Brigade received a report.
A junior high school student disappeared two days ago.
The parents have been looking for him for a day. They have asked all the schools and classmates, but they can't find anyone.
After receiving the alarm message, Lu Chuan and others immediately rushed to the scene in Donggou Township, the southern suburb of the High-tech Zone. (End of chapter)
