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

Chapter 159 Preprocessing Fingerprints

Few people who play cars, especially racing cars, do not modify them.

Of Lu Yao's friends who usually love to play with cars, none of them spent hundreds of thousands, or even millions, on car modifications.

It can be said that there is more than one vehicle modified car to support in a No. [-] arena.

However, the market for vehicle modification is relatively small after all, so most of the modified cars are actually repair shops.

In Haizhou City, there are only a few capable people who can modify cars.

Sanyo Vehicle Repair Factory is one of the best.

Of course, Lu Chuan didn't want to modify the vehicle. He was concerned about the middle-aged man in the photo.

To be more precise, it was the middle-aged man who compared the middle finger of the scissors hand.

Of course, no matter how distinctive a man's fingers are, they will not be as attractive as a little girl's green fingers.

What attracted Lu Chuan's attention was the fingerprint of Wang Qi's middle finger.

There is always a feeling of déjà vu.

As a criminal police officer currently investigating, Lu Chuan's intuition for solving cases may be a bit weak, but his intuition for fingerprints is definitely far superior to others.

For all the fingerprints that Lu Chuan has studied, it cannot be said that he remembers every stripe, but there will always be a sense of familiarity.

In the eyes of fingerprint identification and analysis criminal police, fingerprints are a person's appearance.

Raised ridges, extended lines, each fingerprint has its own characteristics.

Just as there are always a few people who look alike in a crowd, so are fingerprints.

In the photo, the man in the middle compares his hands with scissors, which happens to be able to take a clear picture of the fingerprint of his middle finger.

"Third brother, let me use this photo."

"No problem, just take it away."

Lu Yao had an impression of this photo. It was a photo of the top three finishers and their modifiers after a competition. It was not important.

Besides, even if it is very important, if Lu Chuan wants it, there is no problem.

"You guys play first, I'll come as soon as I go."

Lu Chuan took down the photo and left the crowd.

When it comes to work, Lu Chuan naturally has a subconscious habit of vigilance.

More than ten meters away, Lu Chuan took out his mobile phone and re-photographed the entire photo.

The focus is on the remake of the middle-aged man's fingerprint collection.

Of course, due to the pixel problem of the photo itself, the collected fingerprints are relatively blurred, but it should be usable after some processing.

With Lu Chuan's intermediate fingerprint collection skills, this difficulty did not bother him. Within a few minutes, the photo was hung on the wall again.

Racing cars, of course, cannot just be racing cars.

However, Lu Chuan did not participate in the follow-up events.

This is probably another benefit of going to the Public Security University. The baptism of ideological education is very thorough, and Lu Chuan has not been contaminated by the bad habits of ordinary rich children.

Looking at the time, it was almost midnight, and there was no need to process fingerprints now.

Lu Chuan just felt that the fingerprints of the middle-aged man were somewhat familiar, so he collected the fingerprints in a cautious and responsible manner.

When you are free, deal with it and compare it in the system.

After all, most of the cases that Lu Chuan came into contact with were major cases, and the fingerprints that he was familiar with probably wouldn't do anything good.

On the second day of the Spring Festival, the Chenguang community was very lively.

On sunny mornings, every family came out to post Spring Festival couplets.

The custom of pasting Spring Festival couplets has different times in different places.

Some are on the day before New Year's Eve, and some are on the morning or evening of New Year's Eve.

There are also postings on the morning of New Year's Day.

The custom in Haizhou City is to post Spring Festival couplets early in the morning on New Year's Eve.

In the impression of the Lu family, even when they were the poorest, they would post Spring Festival couplets during the Spring Festival.

Even when pasting Spring Festival couplets, white flour and water will be used extravagantly to make a paste and act as an adhesive.

Commonly known as white flour paste.

This work, I don't know when it started, it was Lu Chuan who started it.

Maybe it was my college year, maybe my sophomore year.

Lu Chuan can't remember clearly, it seems that one year suddenly, his father let go of many things in the family.

"Dad, the Spring Festival couplets are posted, I'm going to set off firecrackers."

The Spring Festival couplets are not only affixed with pairs outside the door, but also small parts such as Jingquan Daji, Safe Entry and Exit, Looking Up and Seeing Happy, etc.

As for the flocks of chickens and ducks that Lu Chuan saw when he was a child, he can't see them now.

If there is, it is estimated that they can only be posted on the chopping board in the kitchen.

The breakfast during the Spring Festival is simple, no different from usual.

Lunch and dinner are combined into one, and the whole family eats together.

According to the rules of the Lu family, no one was invited to cook this meal, but the daughters-in-law of each household showed their talents.

Even some men also showed their hands.

Others played mahjong, fought landlords, and smoked and chatted.

There was laughter in the community hall.

Divided into three large circles.

The generation led by Lu Jianguo pushed Pai Gow in the middle of the hall.

The second generation of the Lu family of the Lu Qiqiang brothers played mahjong in the northeast corner.

There are more than a dozen third-generation children of Lu Chuan, some play games, some smoke, and some watch videos.

As for Lu Chuan...

chatting.

"Is your dinner ready?"

"No, my parents are busy."

Shen Yan was wearing cartoon bear pajamas, lying lazily on the bed, staring at the phone screen with big eyes smiling.

"Do you want to come to my house to eat?"

Lu Chuan's heart trembled, knowing that Shen Yan was joking, but he still had a strange feeling.

"Okay, let's have a couple of drinks with Dad, but I don't know where to live if I drink too much?"

"My house only has two bedrooms, where do you want to live?"

As soon as she sent it, Shen Yan felt her cheeks burn, and hurriedly withdrew the message.

"Don't withdraw, I have seen it..."

In the past two months, the chat between the two has been quite bold.

"Hmph, I'll see it when I see it, I won't talk to you anymore, I'm going to get up."

"just got up?"

……

The seventh day of the new year.

Surveying the office now.

Lu Chuan went to work early, mopping the floor, cleaning the table, and making tea, all in one go.

The anthurium by the window has not dried up because of the passing of the holidays.

On the contrary, after a week of wild growth, the leaves become greener and the anthuriums more delicate and beautiful.

The tall and straight figure is very much like the arrogant Shen Forensic Doctor.

Click.

Lu Chuan took a photo of anthurium and sent it to Shen Yan.

"Good morning, Lu Chuan, happy new year!"

Liu Guodong was always the second to come to the office after Lu Chuan came.

"Master, Happy New Year!"

During the Spring Festival, the prospecting office once got together.

It was organized by Liu Guodong and went to Wang Kai's house to pay New Year's greetings.

The current survey office is not like an action group, because it was established late, and Wang Kai is at the senior level.

The other action groups also gathered for the New Year, but they went to the home of the retired old leader.

"Is there a morning meeting today?"

Lu Chuan put down his anthurium and handed the enamel jar to Liu Guodong.

"Today is a heart-warming meeting, and it may take a little longer."

During the Spring Festival, Haizhou City can be described as calm and calm.

Of course there were cases, but no homicides occurred.

For the criminal investigation detachment, as long as there is no homicide, the rest is not a big deal.

After Liu Guodong left, Lu Chuan turned on his computer and started his day's work.

In fact, the current survey has not had a lot of work recently.

If there is no homicide, there will be no scene, and there will be no need to be present for the current survey.

As for the cases in various districts and counties, they naturally have their own people to investigate.

If they all pointed at a few people from the Criminal Investigation Detachment, they would be too busy to handle it.

What Lu Chuan wanted was the familiar fingerprint he found seven days ago in the No. [-] arena.

Now that I have nothing to do, just deal with it and see if there is any gain.

The re-taken fingerprint photos are somewhat blurred and need to be de-noised to improve clarity.

This is the first time that Lu Chuan has used photos and fingerprints taken by accident for identification and analysis.

When he was in college, Lu Chuan heard from his teacher that some cases were solved through fingerprints extracted from ordinary photos.

Unexpectedly, Lu Chuan also met one himself.

The progress of the pretreatment was very fast. Within 10 minutes, Yang Sen and Lao Bai had just stepped into the office door, and it was over.
