Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 143 Fingerprints on the Wine Bottle
Obviously, among all the people, Wang Song was most concerned about whether Lu Chuan could succeed in the comparison.

Just like many men, they always like to care about how many seconds other people can last.

But he never considers what others do for one second or a hundred seconds, and what it has to do with him...

Wang Song took a step ahead, and the others also stubbed out their cigarettes, and followed behind.

It's time to reveal the results.

The goddess of luck cannot always favor anyone.

The system on Lu Chuan is not the Lady Luck system either.

So, miracles don't happen every time.

On the computer screen, the words "comparison failure" were very glaring.

Standing in front of the computer, Wang Song was a little lost.

Lu Chuan's expression was also a little gloomy.

Lu Chuan chose the exact match mode, and if it failed, there were only two possibilities.

One is that the target person for fingerprint comparison has not left fingerprints in the system.

In this case, you can really wait.

One day, maybe a police station will enter the target person's fingerprints into the system, and the case will naturally have hope of being solved.

However, no one knows what day it is.

Or, whether that day will come, no one knows.

The second is that Lu Chuan failed to preprocess the fingerprints. During the comparison, none of the fingerprints had anything in common.

In this case, Lu Chuan can only perform secondary preprocessing on the fingerprints.

Although it was time to get off work, everyone did not disperse.

At 08:30 in the evening, Lu Chuan frowned deeply as he looked at the words "comparison failed" on the screen for the second time.

"Not yet?"

Wang Song's expression was more anxious than Lu Chuan's, but he couldn't help much, so he could only watch from the sidelines.

Lu Chuan shook his head: "I used different image transformations and used different software for the two preprocessing of this fingerprint, but the final results are the same."

Different methods, different software, the final pre-processing fingerprint results are the same, which shows with a high probability that Lu Chuan's fingerprint processing is no problem.

The reason why the comparison failed was because the murderer's fingerprint sample was indeed not in the system.

This is very difficult.

Wang Song slumped on the chair like a deflated ball.

Really... there is no other way?

the next day.

Song Jiangguo personally came to condolences to the criminal police who participated in the fingerprint battle.

Although the case of Zheng Bin's murder has no clue, it is an indisputable fact that Lu Chuan successfully solved two homicide cases.

Moreover, both suspects confessed to the crime yesterday.

This is the best Spring Festival gift Haizhou Public Security Bureau has received.

When the leader came, it was naturally impossible to do so empty-handed.

This may be the best logistics support in the previous fingerprint battles.

In front of Lu Chuan, Song Jiangguo was full of kindness: "Lu Chuan!"

"Okay! Very good! It's a good job this time!"

"If there is any difficulty, give them feedback at any time."

Song Jiangguo turned to look at the director of the office: "You must do a good job in logistical support."

Song Jiangguo has always had a deep impression of Lu Chuan.

From the case of my father-in-law being stolen, to the robbery that almost affected the entrepreneur's investment.

Lu Chuan's performance can be said to be quite eye-catching.

Coupled with Lu Chuan's performance in several murder cases in the past six months, Song Jiangguo has a feeling that he saw himself when he was young.

"Pay attention to rest and combine work and rest. Yesterday I heard that you were busy until after eight o'clock. How can this work?"

After eight o'clock...

As a criminal police officer, when you get off work at [-] o'clock is considered overtime.

Of course, no one present was against Song Jiangguo.

Lu Chuan stood straight, with his chest up and his head up, like a proud little rooster.

What is the leader condolences for? Is it really just condolences?

Song Jiangguo was obviously very satisfied with Lu Chuan's mental state.

Hurrah, seven or eight people left the meeting room, leaving behind boxes of Pulse, Red Bull, and Black Card.

Gao Wenxiang rubbed his nose and tore open a bottle of Red Bull: "Does this mean you won't be allowed to work overtime?"

Why don't you work overtime and make a bunch of energy drinks?
I didn't follow up on Gao Wenxiang's complaints. After so many years, everyone is used to it.

They sat back to their seats one after another, picked out the fingerprints that looked pleasing to the eye, and continued to fight.

Yesterday afternoon, although Lu Chuan did not gain anything, the others achieved a lot.

Sun Hao once again matched a fingerprint. Although it was not a major case, it was a good start for this fingerprint battle.

Gao Wenxiang was lucky and got a fingerprint.

This made others nervous.

This year's cases were originally few, and there were only a dozen of them that were easy to compare, but now they have already matched three.

According to the number of cases that can be compared with five or six cases in previous years, there are only two or three soft persimmons left.

The next day, everyone seemed to be smoking less.

Lu Chuan did not dwell on Zheng Bin's case yesterday.

After so many years, it is not surprising that Lu Chuan failed to settle the case that the experts from the provincial department have dealt with more than once.

Gao Wenxiang has already exchanged seats with Wang Song.

At this time, if you want to say that the person who is the most relaxed, it may have to be Gao Wenxiang.

Holding a battle result in his hand, he is stable in this fingerprint battle.

Even if there is no achievement in the future, it can be said.

This is also the norm in every fingerprint battle.

Under normal circumstances, most people return empty-handed, and if one fingerprint can be successfully compared, that is a big deal.

The fingerprint competition held by the Ministry of Finance has similar meanings.

Although the criminal police who can participate in the fingerprint battle between the provincial government and the department are all the most skilled existences in the city, the fingerprint competition between the provincial government and the department is also more difficult.

And there is no image case for the sake of face.

The cases that can enter the fingerprint battle database of the provincial government are really old cases.

Of course, it's not all homicide cases, arson, robbery, theft, health, etc., there are all kinds of cases.

"Go, smoke two?"

Gao Wenxiang, who was already lying flat, wanted to smoke two if he had nothing to do.

Lu Chuan shook his head: "Brother Gao, you go first, I will take care of this right away."

With his left hand, he pushed the Zhonghua Cigarette on the side of the table, while Lu Chuan kept his right hand, and was highly concentrated, staring at the fingerprints that had been processed to a critical moment.

Gao Wenxiang nodded and picked up the cigarette: "Take it easy and don't try too hard."

In one morning, Lu Chuan had already obtained the fingerprints of two homicide cases.

The first case was similar to Zheng Bin's case yesterday. After the fingerprint processing was completed, the fingerprints were not compared in the system.

Now Lu Chuan is dealing with the fingerprints of another case.

Gao Wenxiang had also heard about this case.

A murder case three years ago.

The victim was a high school student who had just finished the college entrance examination and was beaten to death while attending a class reunion.

The crime scene was not monitored, and the witnesses were all too drunk at the time, and couldn't remember the murderer's appearance at all.

All he knew was that the other party was also a young man, Huang Mao.

At that time, the impact of this case was very great. For a student who had just finished the college entrance examination, his bright life came to an abrupt end.

What the murderer destroys is not only a life, but also a future with infinite possibilities.

But the detection of a case has nothing to do with influence or public opinion.

The murderer should have killed with passion at the time, and then ran away.

Nothing was left at the scene except for a shattered beer bottle.

Yes, the murderer smashed a beer bottle and stabbed it into the victim's neck.

The carotid artery ruptured, hemorrhaged, and died.

On the wine bottle, the criminal police handling the case collected three blood fingerprints.

Two of them were so sticky together that it was impossible to tell them apart.

The last remaining one was extremely deformed due to excessive force and fingerprints left on the cylindrical surface.

After several times of analysis, it was also entered into the fingerprint database of the provincial government's fingerprint battle, but it was still not detected.
