I'm a Super Cop

Wang Defa originally thought that he was a very smart person and would consider all aspects when doing things, but eventually he met Gu Chen, a trainee policeman with Citroen on his shoulder band.

He thinks that Gu Chen's opinion is not enough to convict. After all, this is only speculation, which is not evidence at all.

But Gu Chen that kind of confident eyes, seems to be more sharp than his own in the market.

It's like two negotiators who want to have a business negotiation, but at the beginning, their momentum is firmly suppressed by the other side.

No matter how you pretend to be strong, the other person seems to be able to see through your mind.

Wang de found that in the face of such a top player, Gu Chen's self-confidence seems to come from his hands holding absolutely unfavorable evidence.

"What are you trying to say? I'm very busy. I don't have time to speculate with you here. " Wang Defa took out his mobile phone.

In doing so, it is also to shift one's own conscience.

Gu Chen learned from officer Wang's posture and pounded the table, startling everyone including officer Wang.

"Wang Defa, so far, I advise you to be honest." Gu Chen suddenly hard up: "because of that cup of water, you still show the flaw."

"You Are you sure? " Wang Defa coldly took a glance at Gu Chen and said, "you police, don't you always tell evidence? Although the glass of water was prepared by Zhao Xiaomi for me, how about that? Can the water cup talk? Will tell you what happened that night? It's just ridiculous. "

He knew that Gu Chen had actually found his own death spot.

That's the point, but he wants to spell it again.

He didn't believe that Gu Chen could reproduce what he had done through a water cup.

Solving problems is another thing.

Gu Chen is very happy to see Wang Defa pretending to be calm. With the reward of 100 cases handling experience, Wang Defa's every move betrays himself.

Maybe it's a fan of the game.

Maybe it was Wang Defa's so-called calmness that he tried to hide from the world.

Such a cover up made Gu Chen feel that his reasoning was completely correct. He raised his voice and said, "there were only three people who had been to Zhao Xiaomi's house that night."

"I don't know how many people it is." Wang Defa twisted his head and shook his legs. His eyes did not dare to look at Gu Chen.

"As long as you know, we have already inquired about two of them, and the drinks they drink are exactly the ones we mentioned before, that is, the drinks left in several glasses in the sink."

Gu Chen's thinking started here

If you don't let this guy know clearly where his flaws are, I'm afraid this feigned calm posture will continue.

"So, first of all, I can be sure that the glass of water on the table is really for you, but we did find something abnormal on this glass of water, that is, fingerprints."

Said here, Wang Defa slightly turned his head, coldly aimed at Gu Chen.

"You don't have to be so nervous." Gu Chen said with a cold smile: "after testing, it's just the fingerprint of your ex-wife Zhao Xiaomi."

"Since it's not my fingerprint, what did you do with a surprise?" Wang Defa breathes a sigh of relief, feeling that Gu Chen seems to be deliberately playing with himself.

When you wait until you kill, it's like playing a game with the hunter.

Wang de discovers that he is the so-called prey.

He deeply felt that Gu Chen in front of him was not simple. He was completely led by him now. He could not tell you what sudden surprise he would bring you.

"I wonder, why don't you have your fingerprints?" Gu Chen confidently raises the question, as if he knew the result for a long time.

"You ask me, who do I ask?" Wang Defa took a deep breath and held up his stubborn temper.

Gu Chen opened his mobile phone, suddenly got up and went to Wang Defa. He showed him the pictures of his mobile phone: "these pictures are provided by the technology department."

"Fingerprints?" Wang Defa was stunned.

"Yes, fingerprints." Gu Chen nodded: "these are the fingerprints of the two suspects before. They have touched the cup. However, since the drinks they drink are iced drinks, due to the hot weather, water molecules in the air will condense into water on the wall of the cup. With such cups, no clear fingerprints will be left."

Seeing Wang Defa's dignified expression, Gu Chen continued: "so the pictures you see are some unclear fingerprints, which just confirms that the drinks they drank were collected by Zhao Xiaomi and put in the vegetable washing pool, and the last cup of water is specially prepared for you."

"But I didn't drink water." "I didn't touch the cup, so you can only find my ex-wife's fingerprints, and the glass of water may have been there all the time, maybe my ex-wife drank it herself," Wang said with a strong smile

"No, you wanted to drink, or you moved the cup, but because you found that you missed it after the murder, you used a tissue to wipe your fingerprints off the cup, and cleaned up the scene before leaving in a hurry."Wang Defa was stunned and did not open his mouth. Gu Chen then said: "I also know that you are a very self disciplined person, and you have serious stomach problems. You never drink iced drinks."

"As an ex-wife, Zhao Xiaomi must pour you warm water, and warm water has no effect on the glass."

"That's why the fingerprints of Zhao Xiaomi left on the cup are so clear."

Why is Gu Chen so sure? Because Zhao Xiaomi's roommate Zhao Wenjing often gets some information from Zhao Xiaomi's mouth.

It is precisely because of this that Gu Chen understands what hobbies and faults Wang Defa has, including the size of his shorts and the size of his shoes, which are also the talks between women.

After listening to Gu Chen's explanation, Lu Weiwei said, "brother Gu, do you mean that Wang de wiped off the fingerprints on the original cup with a tissue in order to clean up the scene?"

"That's right." Gu Chen nodded positively.

"No wonder." Police officer Wang also said: "no wonder you were in the garbage can, like picking up a paper towel into the evidence bag. Is that the consideration?"

Police officer Wang was very confident. In the search at that time, he was always very careful.

But before leaving, Gu Chen picked up the used paper towel back to the evidence collection bag, which surprised officer Wang.

But now think about it, but with this consideration, I almost missed the key evidence.

"Shall we continue?" Gu Chen sees that Wang Defa doesn't speak, and shows the evidence he has once again.

Gu Chen refreshed the mobile phone to the latest fingerprint collection picture, and said with one stroke: "you deliberately wiped the fingerprints on the water cup, thinking that you could hide it from the sky. Maybe your self-confidence made you ignore this point. Don't you know that fingerprints can also be extracted from paper towels? And the fingerprints on the cup can also be seen in detail in terms of technology. "

"I I really don't know what you're talking about? " Wang Defa lowered his head and his nervous legs trembled.

He's panicked now. He's completely flustered.

In the face of Gu Chen's strong evidence of the bombardment, Wang Defa simply can not resist.

Gu Chen said with a smile: "then I can tell you that if you want to extract fingerprints on paper towel, you can use colored ethyl α - cyanoacrylate, which can be chemically developed."

To smash Wang Defa's stubbornness, Gu Chen is serious and won't give him a chance to refute.

In the mobile phone, it is the picture just sent by forensic Liu. It is the fingerprint evidence that has been successfully extracted from the tissue.

"Wang Defa, I advise you to be honest." "If you still like sophistry, I can use the police car to take you to the technical section to see if the fingerprints on it are you wang Defa," he said

Police officer Wang completely breaks Wang Defa's last stubbornness

Now, he's speechless and doesn't know how to organize language.

Sophistry?

It doesn't exist.

It's ridiculous to think that a tissue discarded in the garbage can is actually evidence of capsizing.

"Can tissue extract fingerprints? Hehe, it's the first time I've heard it. " Wang de found that in the absence of hard gas, he also became depressed.

"What? You don't believe it? " Gu Chen felt that the guy was still in doubt, but he was very happy to tell him: "the fingerprint extracted from the paper towel has something to do with the roughness of the tissue. If it is too rough, the fingerprint will not have the identification value."

Seeing Wang Defa's solemn eyes, Gu Chen continued: "but fingerprints, which are generally left on hard objects, will not disappear unless they are wiped, but you have not destroyed them in time."

in fact, the latest technology of the crime, even if the suspect's fingerprints on the crime scene disappeared, can be re extracted.

What's more amazing is that the fingerprints on the leather bag can last for more than 30 or 40 years in a dust-free and dry environment.

In the interrogation room, suddenly, Wang Defa's mobile phone in his hand fell to the ground.

"When I don't want to kill the truth, I don't want to stand up and kill me
