Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Dong Jun was very calm when being questioned by the police.

Like other neighbors, they showed emotions such as nervousness, fear, and curiosity.

However, when he heard the police discussing in the corridor that Qin Weiwei was killed and did not die naturally, his heart stopped.

Dong Jun couldn't 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 managed 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 speak.

In fact, Dong Jun did all this very cautiously and carefully.

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 on the body's back on the bathroom floor tiles gave it all away.

From this, Lu Chuan became suspicious.

Next, we will focus on investigating the bathroom.

Thus, the words Dong Jun wrote on the mirror were discovered.

Wang Zhaokai answered Dong Jun's question: "Qin Weiwei's first death scene was in the bathroom."

"At that time, Qin Weiwei died and fell on her back, so her back was marked with grid marks on the bathroom floor tiles."

"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 hadn't been motivated at that time and hadn't done what he did next...

Just nothing.

Maybe that's really what 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 doors were locked, and the windows were locked. The cause of death of the deceased was cerebral hemorrhage.

There is also a corresponding history of encephalopathy 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 one……"

"it's actually really easy……"

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 to the anti-lock button.

"The old-fashioned security door is not very airtight. Take the rope out from the side, then lock the door, pull hard, and the lock will be on."

"Because I tied it with a live rope buckle, and the untied thread of the live rope was on the outside. I yanked the button hard to untie it, and then took the rope away. The door was locked without anyone noticing."

Dong Jun explained clearly the motive for the murder, the murder process, and how to form the secret room.

At this point, the case has been successfully solved.

One squadron office.

"Brother Wang, I checked the death of Dong Jun's child, and it seems..."

Everything that led Dong Jun to kill Qin Weiwei stemmed from the accident five years ago.

At that time, after Dong Jun's child died, someone raised the issue of Qin Weiwei's failure 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 investigated the situation back then and found that Dong Jun was also quite miserable.

That year, his son died, his wife divorced, he was defrauded during the renovation, and he owed more than one million yuan in project payment.

Just like Dong Jun said, he almost jumped off the building.

"Actually, I think Dong Jun has to be blamed for this matter. My child is so young. He threw the child away and left. Who can he blame if something happens?"

"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 were taking 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 child's biological father. It would be more difficult for the child to lose him than anyone else."

"Besides, who cared about us when we were kids? If we didn't run around outside every day, nothing would happen."

Let's chat, everyone has different opinions.

What happened five years ago, we can’t actually say who is right or wrong.

But Dong Jun blamed Qin Weiwei for his son's death, which was really wrong.

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 method of the secret room Dong Jun built was very simple, it was something he couldn't imagine when he didn't expect it.

This was also Lu Chuan's first time coming 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 controversy over 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, sooner or later it will subside.

Everyone in the criminal police brigade can finally go home and have a good sleep.

For this case, more than 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 the person can be handed over to the detention center.

After the court is held and the detailed trial is completed, 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.

In his case, it was basically a death sentence.

The probability of death with reprieve is very small.

After all, it was planned for three years. 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, asking 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)
