There were no waves in the arrest of Zhang Yuhui.

Zhang Yuhui, male, 36 years old, engineer of a software company, bald, otaku.

Last night, because he stayed up late to write code, he didn't get up in the morning, and when he woke up, he was pointed at the muzzle of a black hole.

"What's it called?"

"Zhang ...... Zhang Yuhui ......"

Zhang Yuhui graduated from a prestigious university and has experienced a good higher education, so he knows very well that if he is not dreaming, then the one who can break into his room with a gun must be the police or the army.

I'm just a code otaku and haven't started a family, but my energy is squeezed clean by the boss of the company, and I don't have time to undermine social stability.

My work is the program code of smart electrical appliances, which does not involve secrets, nor has I communicated with foreigners, so it should not involve the betrayal of state secrets.

Also, the clothes that the other party is wearing...... Apparently a police uniform.

Therefore, when the other party asked his name, although Zhang Yuhui was very nervous, he still replied tremblingly.

"Do you know why I arrested you?"

"No...... I don't know ......."

Zhang Yuhui replied very honestly, he really didn't know.

"Take it away!"

The interrogation room of the Yunfeng City Criminal Investigation Detachment.

"Eight years ago, June 28th, where were you?"

"I don't know."

"Zhang Yuhui!"

Chen Wu personally interrogated Zhang Yuhui, eight years ago on June 26, Chen Wu took up the post of head of the criminal investigation detachment, and on June 28, a headless body was found.

Therefore, Chen Wu has a very deep memory of the time node of that year.

"Eight years ago, the abandoned grain depot on Weiwu Road, headless corpses, have you forgotten?"

"Oh, you said that case, I know, the headless case, it's not too far from my house."

Chen Wu was almost choked up and said that he didn't come to speak.

"Do you know or not?"

Chen Wu's eyes were like eagle falcons staring at Zhang Yuhui on the interrogation chair: "Zhang Yuhui, let's say, who was the person you killed back then, why did you kill people, and where did you hide your head?"

Well?

Zhang Yuhui was stunned.

What killing?

What head?

"Captain Chen...... What did you say...... Murder?"

Zhang Yuhui finally reacted: "You guys...... Think I've killed someone?"

Zhang Yuhui's somewhat confused expression turned frightened: "I didn't kill anyone! Wronged!"

Bang!

Chen Wu got up and slapped the table: "Zhang Yuhui!"

"Didn't you just say that you knew about that case, and now you're pretending to be innocent, it's too late, right?"

Zhang Yuhui felt a little innocent: "In the case eight years ago, everyone in our community collected fingerprints and DNA, of course they know, how can the old people who live there not know."

Chen Wu paused and decided to play his hole cards.

"The dagger we found inside the corpse has your fingerprints on it, and you still want to quibble?"

"Fingerprints?"

Zhang Yuhui was stunned again: "Captain Chen, it's impossible, really."

"I was on a business trip in May that year, and I didn't come back until a few days after the crime occurred in June, so I had time to commit the crime, and I did the ...... of writing at that time."

The investigation against Zhang Yuhui was launched again.

The results were quickly fed back.

"Team Chen, the identity of the deceased has been found."

Although Zhang Yuhui himself did not admit that he had killed someone, after Lu Chuan confirmed the fingerprints of the other party, the criminal police who handled the case launched an investigation into his interpersonal relationships.

As a result, the identity of the deceased was discovered.

It turned out that the deceased's name was Zhao Yali and she was Zhang Yuhui's ex-girlfriend, but because Zhang Yuhui couldn't afford to buy a house and didn't understand the humor, the two broke up at the beginning of eight years ago.

"After the breakup, I thought she had returned to her hometown, and then there was no contact......

Back then, Zhao Yali was a model and often worked in Yunfeng City and Tianzhou City

, Haizhou City and other places to receive advertisements and take photos.

So her whereabouts are uncertain, and Zhao Yali is from another province and came out to work at a very young age.

"She had very little contact with her family, and when we were in the relationship, I heard her say that she had never been home in all these years since she came out, and she had never been in contact with her family."

Zhang Yuhui's words also explain why there is no report of Zhao Yali's disappearance.

I haven't contacted my family for many years, so naturally there is no saying that I am missing or not.

Zhang Yuhui's whereabouts eight years ago were investigated clearly.

According to the results of the forensic doctor's identification of the corpse at that time, it was basically determined that the deceased died in the circumstances at that time, and the time of death was about half a month.

In other words, the specific time of death of the deceased was around June 13.

And during this time period, Zhang Yuhui was indeed on a business trip in the field, and he had no time to commit the crime at all.

Moreover, Zhao Yali and Zhang Yuhui broke up at the beginning of the year, and adjusted the mobile phone call records of the year, showing that the two have not been in contact since they broke up.

But the question is, why is there Zhang Yuhui's fingerprint on the handle of the dagger that killed Zhao Yali?

Once again, the investigation of the case seems to have reached an impasse.

When Zhao Yali was killed, Zhang Yuhui was not in Yunfeng City, and the possibility of committing a crime had been ruled out.

However, a dagger with Zhang Yuhui's fingerprints was found inside Zhao Yali's body.

"Team Chen, is it possible that the dagger was taken by the murderer from Zhang Yuhui's house, and then wanted to frame it for the other party?"

The speculation of the subordinates may be the only possibility at the moment.

Chen Wu's target was naturally aimed at Zhang Yuhui's neighbor back then.

The investigation work was carried out in full swing.

At the same time, in the fingerprint battle conference room, Lu Chuan passed two more cases in his hands after a morning of struggle.

The first case was a bit unlucky, and the analysis of fingerprints was very unsatisfactory.

Lu Chuan used three methods successively, and the pretreated fingerprints obtained were all different.

This shows that Lu Chuan's preprocessing of fingerprints is a failure.

Advanced fingerprint identification and analysis, it is obviously impossible to get all fingerprints.

But this fingerprint is the only fingerprint that Lu Chuan has ever encountered, and the processing has completely failed.

The second case was more lucky, Lu Chuan only did one analysis, and he successfully matched the suspect.

So far, the number of successful cases in Lu Chuan's hands has also risen from four to five.

The number of points has risen from 40 to 50.

Beginning in the afternoon, the efficiency of the expert group gradually reached its peak.

Many experts have begun to gain results.

"Hah! The third fingerprint!"

Zhao Zhigao was very excited, and in two days, he won three fingerprints, which was the most brilliant achievement achieved by Zhao Zhigao since he participated in the fingerprint battle.

"Congratulations."

Lu Chuan sincerely congratulated, although there was no homicide in the other party's comparison, but the case that can enter the fingerprint battle of the provincial department will not have a small case similar to the theft of electric vehicles.

"Oh, it's far worse than you, I'm here today, and the rest will learn from you."

Although Zhao Zhigao couldn't learn Lu Chuan's set, he learned a few tips taught by Lu Chuan for the application of PS software, which was also an important reason why he was able to compare the third fingerprint.

Lu Chuan smiled, he wouldn't cherish himself.

Whoever can learn is a good thing, after all, a person's energy is limited.

Compared with the five cases, it has actually consumed a lot of Lu Chuan's energy.

Not only Zhao Zhigao, but also other experts have generally gained a lot.

Director Tian Rong has firmly occupied the second position, and the number of cases has risen to six.

There are also nearly forty points.

Everything is developing in a good direction.
