Solving the case is a little bitter, but my sister is super sweet

Yanqing urban area.

Lin Xuan and Zhao Qiang stepped out of the police car and entered a residential area with a beautiful environment.

Along the way, Lin Xuan observed his surroundings.

The community in front of you belongs to a high-end residential area.

Although it is outside the Sixth Ring Road, the starting building size is 20,000 to 30,000 square meters.

The apartments in the community look quite large.

Basically, they range from two bedrooms and two living rooms to four bedrooms and two living rooms.

That's what investigation is like.

Not only the scene of the crime must be investigated, but also the surrounding environment of the scene.

Determine something based on the environment.

For example, the missing couple should have some money, not much.

Ordinary people wouldn't rent the houses in this place, and most really wealthy people wouldn't buy them.

Walk into a residential building, second floor.

A trainee police officer sat in front of a house.

When he saw Zhao Qiang, he stood up quickly and shouted: "Master."

Lin Xuan was surprised and looked at the policeman for a few seconds.

"After you leave, I will get another one."

Zhao Qiang smiled and said: "I will take him with me now."

Lin Xuan nodded, "Hello, junior brother."

The trainee policeman looked at Lin Xuan curiously, a little confused.

Lin Xuan and Zhao Qiang didn't care either.

He picked up the shoe covers and gloves from the criminal investigation box on the side and started putting them on.

Enter the scene...

In order not to damage the scene, the criminal investigators conducted a "closed" treatment.

Prevent air circulation. Over time, floating dust will appear in the room, which will damage the site.

After entering, you can smell a musty smell.

Lin Xuan, standing in the entrance hall, frowned.

His super sense of smell told him: There is no smell of blood!

Many people have seen Animal World.

Know that some animals urinate in their territory to mark it.

That's a uric acid smell that can linger in an area for a long time.

Many people have also smelled the smell of blood and know that it is difficult to eliminate the smell of blood.

The reason is that uric acid also exists in human blood.

With Lin Xuan's super sense of smell, the scene was still closed.

If the smell of human blood appears within ten days and a half, it will not escape his sense of smell.

No, it can only explain one problem.

There was no murder at all, no human blood.

Don't talk about whether it was specially cleaned up.

That uric acid smell is too difficult to get rid of.

Even if there is a murderer, he would never think that someone's sense of smell is more sensitive than a dog's nose.

Normally one would not be prepared for this!

To prevent mistakes in your sense of smell.

Lin Xuan still surveyed the scene.

Mainly I wanted to see if there were any signs of being ‘cleaned’ at the scene.

The result...no!

The traces at the scene were obvious. Lin Xuan's super eyesight could see traces of the life of a 'family of three'.

We also found traces that an old man had lived in the second bedroom not long ago.

Finally, determine whether there are any traces of murder.

No.

It proves that the investigators at that time were very careful in their investigation.

Indeed, no signs of homicide were found!

"Let's go see the old people and the children."

Lin Xuan said to the master.

"Didn't find it?" Zhao Qiang's expression was solemn.

"No."

Lin Xuan affirmed: "It's not the scene of a murder!"

If it wasn't the crime scene.

A 5-year-old child happened to say that he saw his father killing his mother at home.

This explains one thing.

The child is lying!

There is also another possibility.

Even the kid didn't know he was lying.

Lin Xuan has seen this situation before.

Remember that ‘time travel’ incident?

Someone took advantage of the victim's mouth and told a huge lie.

And controlling a child to lie.

It’s much easier than changing a person’s memory!

There is another important point.

During the investigation, it was discovered that the child had psychological problems.

A 5 year old child.

Why are you so calm when you see your father killing your mother?

…

Three rings.

An old building in a residential area.

Standing in front of an entrance door, Lin Xuan knocked on the door.

Not long after, a voice of questioning came from the door.

"Who?"

Female, with an old voice.

"Police." Lin Xuan said in a gentle tone.

The door opens.

There was an old woman standing inside the house.

He is about fifty years old.

The old woman looked sad and haggard, with bloodshot eyes.

It can be seen that her sleep quality has been very poor recently.

Lin Xuan could also hear another breathing sound in the room.

The child's breath.

I also heard the sound of the TV.

"Hello, I have something to ask you."

Zhao Qiang on the side smiled and said, "Is it convenient?"

"Please come in." The old woman sighed.

Lin Xuan and Zhao Qiang walked in, and the old woman brought them slippers.

Go into the hall.

Lin Xuan's eyes fell on the sofa and saw a child.

The child sat quietly, his eyes empty and lifeless.

It was as if all the energy and laughter were being held back by invisible shackles.

There was no expression on the little face.

Just sitting there quietly, as if isolated from the world, watching cartoons on TV.

Something is wrong... Lin Xuan looked surprised.

Children of this age are supposed to be lively and active, and dogs have to run away when they see them, so they can’t be offended.

But the demeanor of the child in front of me is very abnormal!

"Has the child been like this before?" Lin Xuan looked at the old woman.

“It’s only been like this since half a year ago.”

The old woman looked at her little grandson with a loving expression, "I checked, and the doctor said it's normal."

You call this normal?

Lin Xuan frowned and looked at his master.

Zhao Qiang also nodded.

At that time, they also found a psychologist to cooperate with the investigation, and the doctor said it was normal.

It's just that the child's mental state is a little different from that of ordinary people.

Lin Xuan thought about it and walked to the child.

The little boy raised his head and looked at Lin Xuan.

His eyes were straight, his little face was expressionless, and his eyes were not smart.

"Hello, little friend."

Lin Xuan smiled and squatted in front of him. He raised his hand and a pistol appeared in his hand.

The magazine was also withdrawn and handed to the little boy, and asked with a smile, "Do you like it?"

The little boy looked at the gun.

He raised his head and looked at Lin Xuan again, shook his head, and a childish voice sounded, "I don't like it, I miss my parents."

It's so wrong... Lin Xuan put away the pistol and stared at the child's face and eyes.

He stood up and took out his mobile phone.

He made a call.

After the call was connected, he said something.

"Mr. Qian, I want to ask you for a favor!"

...

More than an hour later.

Mr. Qian, the master of psychology in Longguo, appeared in front of Lin Xuan.

When he saw the child for the first time, he was stunned.

Then, he smiled and said a few words to the child.

Using hypnosis induction, he conducted some psychological tests on the child.

Not only that.

He also used many methods to experiment on the child.

In a blink of an eye, two hours passed.

Mr. Qian looked at Lin Xuan with a serious face, "It's not hypnosis."

Lin Xuan also knew that it was not hypnosis.

If it was, the psychologist hired by the case handlers would definitely be able to see it.

"Is it the child's own problem?" Lin Xuan frowned.

"It's not congenital."

Mr. Qian's face turned cold, "Someone used other means to do something to him."

Lin Xuan and Zhao Qiang's faces changed.

The clue appeared!
