Subconsciously picked up the photos in front of you and opened them one by one. Qin Yu's expression changed, but it was different from the previous interrogation. This time, Chen Yan did not keep stinging the other person's face, but sat on the back of the chair with that expression.

It's like watching a show.

Sure enough, Qin Yu did not disappoint Chen Yan.

"Captain Chen, where were these photos taken? The space is so small, but does this have anything to do with me?"

What's the relationship?

Chen Yan raised his waist and looked at Qin Yu's eyes. This time, Qin Yu did not look at each other directly, but turned his gaze unnaturally.

Oh.

"Qin Yu, you are right. The space for these photos is very small, because these photos were taken in the underground pipeline of Binhe Road."

Underground pipeline?

Although Qin Yu had guessed that the other party had found a way to disappear from the surveillance, Qin Yu guessed that it was one thing, and it was another to confirm that this news from Chen Yan.

Qin Yu, who was a little panicked inside, quickly calmed down again.

What if you find a way to avoid surveillance?

Others didn't know how long Qin Yu had prepared for this murder, but he knew it himself. Qin Yu took every detail into consideration.

He has arranged how to avoid surveillance, how to stop Wang Xu's car, what methods are used during the murder process, how to leave no traces, retreat routes, and even clues that confuse the police.

Qin Yu never thought that she could avoid the police's sight. With the dispute between him and Wang Xu, the police would definitely lock on him as soon as possible.

What Qin Yu had to do was never to eliminate the police's suspicion of himself, and even to exaggerate his suspicion in his plan.

For example, he won the bid for renovation at a low price in Hengchang community, such as working downstairs of Wang Xu's house, or even the key, which was deliberately leaked by Qin Yu.

Otherwise, with Qin Yu's caution in planning and implementing the killing of Wang Xu, how could he leave a video of him getting the key?

I have to say that Qin Yu’s plan was successful.

After investigating the situation where Qin Yu configured Wang Xu's keys and learning that he had not implemented the plan, although Qin Yu's suspicion was not completely ruled out, it was much smaller.

What's more, Qin Yu also provided monitoring of the balcony on the 1st floor of Unit 3, Building 1, which also proves to a certain extent that Qin Yujing did not leave Room 202 on the night of the incident.

Afterwards, Chen Yan changed his thinking on the case and finally turned his suspicious eyes to Qin Yu's younger brother Qin Feng.

It was just when it was discovered that the murderer was using the underground pipeline network to avoid surveillance, and the exit was just below Room 202, Unit 2, Building 1, Qin Yu was exposed to Chen Yan's sight again.

Seeing Qin Yu's expression not changing much, Chen Yan really admired Qin Yu's determination. "Qin Yu, you seem to have no reaction to the evidence we found...?"

ha.

Qin Yu suddenly smiled and put down the photo in his hand: "Captain Chen, what can I do? I am most happy if Wang Xu died, although I didn't kill anyone."

"I know you suspect that I killed Wang Xu. Indeed, I have thought so, and have even started planning and even prepared to implement it. That key is evidence, I admit it."

"But I just think so. He was already dead before I could kill Wang Xu."

"If the price still suspects that I killed him, I hope you can come up with evidence."

Yes, that's the evidence.

Qin Yu tried his best to plan for so long?

Isn't it just to not leave any evidence?

Qin Yu left no footprints, fingerprints, and no surveillance cameras at the scene where Wang Xu was killed

He was photographed by a photo of him.

Even in the underground pipeline, Qin Yu also cleared many traces.

Although the surveyors extracted blood in the passage and confirmed that it was the blood that belonged to the deceased Wang Xu, and even found a fruit knife in the corner. After the wound comparison, it was confirmed that this was the weapon, but the survey and reconnaissance team members still did not find it.

The fingerprints left by the murderer.

The shoe prints were not even extracted, this is Qin Yu's cleverness.

What he did not do

The police do not allow them to doubt themselves, but even if they doubt themselves, there is no evidence.

Before and after the underground pipeline was opened, he used a broom to clean up the road he had walked, and all his footprints were cleaned.

Qin Yu's gloves were not taken off during the entire crime, so of course he would not leave fingerprints. As for personal characteristics such as hair and dander, he naturally did not leave them.

Therefore, Qin Yu was fearless because he knew that he had not left any evidence.

There is no way to convict without evidence, so what can even be done if Chen Yan and the others find out that they can avoid surveillance?

After planning for so long, Qin Yu would not make mistakes in this detail.

Chen Yan looked at Qin Yu with a calm expression carefully. This person is really amazing.

Qin Yu is right, evidence can only be convicted, and reasoning alone cannot be sent to prison.

Chen Yan personally went through the entire underground pipeline network. I have to say that Chen Yan admired Qin Yu a little.

Qin Yu cleaned the entire underground pipeline network very cleanly, and the cleaning traces can be seen clearly on the ground.

At the exit, Chen Yan even found a broom that cleaned his shoe prints.

The weapon was also abandoned in the corner of the entrance.

However, no fingerprint was extracted from either the broom or the fruit knife.

No fingerprints, no shoe prints, no hair. Even if Chen Yan discovered that Qin Yu was coming and leaving the crime scene from here and avoiding the surveillance camera, what could it be?

Just as Qin Yu said, if Chen Yan doubts him, he will come up with evidence.

Without evidence, everything is in vain.

But, does Chen Yan have evidence in his hands?

Of course there is!

If not, why bother to interrogate Qin Yu again?

"Qin Yu, I have to say that you are the most cautious and cautious among all the criminal suspects I have ever met."

"Whether it is at the crime scene or the underground pipeline where you avoid surveillance, you feel that you have cleared all traces, foolproof, and left no evidence at all."

Qin Yu didn't say anything, just looked at Chen Yan quietly.

"But, you may not know that the footprints you left on the dust on the access ground can indeed be cleaned with a broom, but what about the shoe prints on the crossbar of the iron ladder at the entrance and exit?"

Iron ladder cross-load?

Qin Yu was slightly stunned: "Captain Chen, are you saying that my shoe prints are left on the crossbar of the iron ladder?" "Haha, it's impossible!"

Qin Yu laughed and tears were almost coming out: "Captain Chen, I am a decoration student, and I still know this common sense."

"Although I have never been to that underground pipeline network, I also know that the crossbar of the iron ladder at the exit of the pipeline network is only the thickness of a thumb."

"What footprints can a person leave when he steps on it?"

"That's iron or not soil!"
