Bro, you are a policeman, not a thug.

"Electric shock, concussion... too many ways can cause a person to become unconscious in water. Even without coma, you only need to make the victim temporarily paralyzed and lose the ability to move, which can cause drowning."

Xiao Mu said coldly: "I can now roughly infer such a plot. It is too easy to make a policeman jump into the lake without hesitation. Just arrange a person in the lake to pretend to drown and call for help."

"This is also completely consistent with our discovery of the victim's state switching. Hearing the call for help, as a policeman, as long as he can swim, how could he not go to rescue?"

"When the victim jumps into the lake, the person under the water can do something to cause him to become unconscious, lose the ability to move, and drown, pretending to jump into the lake to commit suicide."

"It is not difficult to find out from this that there should be more than one perpetrator, and all the daily whereabouts of the victim have been mastered by them."

"Because it is impossible to be so coincidental, it will not be a temporary arrangement. They know the whereabouts of the victim thoroughly, so they can arrange this killing situation!"

The faces of Zhao Xiaotang and others have begun to become solemn.

What is scary is not the killing of police officers, but the purposeful crimes committed by the gang.

Targeting police officers specifically!

If the reasoning is correct.

Whether the next three cases can be solved is no longer important.

"Have you checked the common points of the four victims?"

Xiao Mu looked at Dong Ruicheng.

Meaning: Did the four victims act together, solve the case together, a group, participate in a case, incident, or something else.

Xiao Mu has reason to suspect that the perpetrator's behavior is revenge.

As mentioned in the previous article.

Thirty percent of the police's sacrifices and deaths are from revenge!

"Checked."

Dong Ruicheng's face was gloomy, and he shook his head again, "There are almost no cases that the four of them have participated in together, at most two or three, because they do not belong to the same squadron or group, but... the relationship between the four of them is quite good."

Good relationship... Xiao Mu's eyes were burning.

Good relationship means that they often act together.

For example, eating together, meeting together.

Drinking tea and chatting.

"Have you checked what they did in private, for example..."

Xiao Mu said in a deep voice, "Some illegal and disorderly behavior!"

Don't blame him for thinking so, it's normal.

Which industry doesn't have some bad fish and shrimp?

It's too common for a few rat shits to spoil the whole pot of porridge.

"I have checked."

Dong Ruicheng nodded heavily, "There is no big problem, and the small problem will not lead to such a fatal disaster."

"No, you still haven't found it."

Xiao Mu shook his head, "If the other party is coming for these four people, the four of them have not participated in certain cases together, then they must have done something, or done something unintentionally, or even this kind of unintentional thing that they didn't even notice anything wrong, but it led to a fatal disaster."

The purpose of killing is sometimes not necessarily hatred, there are many causes and effects.

For example, silencing, hiding, hearing what you shouldn't hear, seeing what you shouldn't see, saying what you shouldn't say...

Sometimes a word may lead to a fatal disaster.

Go ask the old friends in Northeast China because of a sentence "What are you looking at".

Fighting, death, are there few?

"Check whether the four of them have had any contact in the past one or two months, and what they have done together."

Xiao Mu ordered, "The clue is here!"

Why recently?

Isn't the reason obvious?

Would a person who can kill people by "accident" be a simple person?

And it was a gang crime, most likely a "professional".

Xiao Mu had watched many movies about cases in the past.

I often see a profession: accident maker, coincidence fabricator, accidental killer.

No matter what the name is, it means that this profession uses "coincidence and accident" to kill people.

Don't think that this profession does not exist.

For example, killers, mercenaries, scavengers, bounty hunters...etc.

Do they exist differently, but ordinary people have no chance to contact them at all.

It has been said in the past, who are the people who can contact these people?

Is it possible that the four victims were together at a certain time point and encountered something together.

And this matter involves someone who can contact a special professional, such as an "accident maker".

Did this person realize that the four victims were policemen, or did the four victims do something, discover some secret, which made this person want to kill?

So this person used special channels to find an "accident maker".

Of course, don't talk about accident makers.

A killer is a killer, just a little more advanced.

Is this reasoning reasonable?

"One more thing."

Xiao Mu's eyes flashed with coldness, "We can't be sure that the other party wants to kill only four people. Will there be a fifth or sixth person? Do you understand what I mean?"

Everyone nodded.

"Check everyone in the Jinling Criminal Police Brigade and ask them."

Xiao Mu said coldly: "See if there are other people who have contacted and acted with them during the time period, except for the four victims who acted together."

"Yes."

Everyone responded and began to investigate.

...

Xiao Mu and Zhao Xiaotang came to the second scene together.

The home of the victim who died of "mechanical asphyxiation".

Standing in front of the bed.

The bed in front of him still maintained its "original" appearance and had not been moved.

The traces on the bed reveal the victim's state when he died.

There are no signs of struggle, not even signs of movement.

It's like a person died quietly in his sleep.

"Can you deduce it?"

Zhao Xiaotang has long admired Xiao Mu's brain.

"No need to deduce, I've seen similar case files before. In 2010, the perpetrator was a university professor."

Xiao Mu stared at the big bed in front of him, "It was a wife-killing case, and the perpetrator's means of killing was just a wet wipe."

This is also what he said to Dong Ruicheng at the time, "There are traces to follow."

Zhao Xiaotang took out his mobile phone and quickly found the case through the police big data system.

After reading the file, the corners of his mouth twitched and he was stunned.

Yes, it is very similar to the case in front of him.

But the means are relatively "rough", and there are traces to follow.

And the case in front of him is a bit scary.

It's like... an upgraded version!

Because the perpetrator is not the victim's partner, this can't fool them, a group of old criminal detectives.

Xiao Mu came to the living room and investigated the traces in the living room.

The file records: The victim was mopping the floor when he accidentally slipped and hit the back of his head on the coffee table.

Does it remind you of anything?

Yes, the fourth case.

The victim stepped on a marble, accidentally slipped, and fell down with a nail piercing the back of his head and died.

If the four cases are combined, there are two coincidental hits on the back of the head in one case.

Is it still a coincidence?
