Bro, you are a policeman, not a thug

"Electric shock, concussion... there are so many ways to cause a person to become unconscious underwater. Even without causing a coma, just causing the victim to become temporarily paralyzed and lose the ability to move can cause drowning."

Xiao Mu said coldly, "I can now roughly deduce such a plot. It's too easy to make a police officer jump into the lake without caring about his own life. All we need to do is arrange for someone in the lake to pretend to drown and call for help."

"This is completely consistent with the state change we experienced when we discovered the victim. Hearing the cry for help, as a police officer, as long as he knew how to swim, how could he not go to rescue him?"

"When the victim jumped into the lake, the person underwater could have done something to make him unconscious and unable to move, causing him to drown and faking suicide by jumping into the lake."

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

"Because it can't be such a coincidence. It can't be a temporary setup. They must have known the victim's whereabouts thoroughly before setting up this murder!"

The expressions of Zhao Xiaotang and others began to become serious.

What is scary is not the killing of police officers, but the fact that gangs commit crimes with a purpose.

Crimes specifically targeting police officers!

If the reasoning is correct.

It doesn’t matter whether the next three cases can be solved.

"Have you checked the commonalities among the four victims?"

Xiao Mu looked at Dong Ruicheng.

What it means is: Did the four victims act together, solve the case together, form a team, participate in a case, incident, or something else?

Xiao Mu had reason to suspect that the perpetrator's behavior was an act of revenge.

Said before.

Thirty percent of police officers who died in the line of duty were killed in retaliation!

"researched."

Dong Ruicheng's face darkened as he shook his head. "There are very few cases in which the four of them have ever been involved together. At most, two or three of them have been involved together, because they don't belong to the same squadron or group. But...the four of them have a very good relationship."

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

A good relationship means that you will often act together.

For example, having a meal together or meeting together.

Drink tea and chat or something.

"Have you ever checked what they did privately, such as..."

Xiao Mu said solemnly, "Some illegal and disorderly behavior!"

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

Which industry doesn’t have some rotten fish and shrimp?

It is too common for a few bad apples to spoil the whole barrel.

"researched."

Dong Ruicheng nodded heavily, "There's nothing serious wrong with me. A minor problem wouldn't lead to such a fatal disaster."

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

Xiao Mu shook his head. "If they were targeting these four people, and they haven't been involved in any cases together, then they must have done something, or done something unintentionally, or even something they didn't even realize was wrong, yet it brought about their own deaths."

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

For example, silencing someone, hiding someone, hearing something they shouldn't hear, seeing something they shouldn't see, saying something they shouldn't say...

Sometimes a single word can lead to fatal consequences.

Go ask my friend from Northeast China because of the sentence "What are you looking at".

Aren’t there few fights and deaths?

"Check whether these four people have had any contact at any time in the past one or two months, and what they did together."

Xiao Mu ordered, "The clue is right here!"

Why recently?

Isn't the truth obvious?

Could someone who could use an 'accident' to kill someone be a simple person?

Moreover, it was a gang crime, and it was most likely a "professional" crime.

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

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

Whatever the name, it indicates that this profession is to use "coincidences and accidents" to kill people.

Don't think this kind of career doesn't exist.

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

Does it exist differently? It’s just that ordinary people have no chance to come into contact with it.

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

Is it possible that the four victims were together at a certain point in time and encountered the same thing?

This matter involves someone who has access to a special profession, such as an 'accident maker'.

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

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

Of course, let’s not talk about accident makers.

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

Is this reasoning sound?

"Another point."

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

Everyone nodded.

"Investigate and question everyone in the Jinling Criminal Police Brigade."

Xiao Mu said coldly: "Let's see if there were any other people who had contact with them or acted together with the four victims during that time period."

"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 from "mechanical asphyxiation".

Standing in front of the bed.

The bed in front of me still maintained its original appearance and had not been moved by anyone.

The marks on the bed revealed the victim's condition at the time of death.

There were no signs of a struggle, not even of movement.

Like a person dying peacefully in his sleep.

"Can you deduce it?"

Zhao Xiaotang has long admired Xiao Mu's intelligence.

"No need to reason. 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. "That was a wife-murder case, and the perpetrator used only a wet wipe to kill her."

This is also why he said to Dong Ruicheng at that time that "there are clues to follow".

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

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

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

But the method is relatively "crude" and there are traces to follow.

The case before us is a bit scary.

It’s like…an upgraded version!

Because the perpetrator was not the victim's partner, this fact could not fool these experienced detectives.

Xiao Mu came to the living room and checked for traces there.

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 anything come to mind?

Yes, the fourth case.

The victim stepped on a marble and accidentally slipped, and after falling, an iron nail pierced the back of his head and he died.

If the four cases were combined, one case would show two coincidental hits to the back of the head.

Is it still a coincidence?
