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

Surveying the office now.

Lao Bai handed Lu Chuan a cup of tea.

"Don't work so hard, take a break first and smoke a cigarette to get some air."

Wu Kaiyue sent a total of 56 pictures.

In the morning, Lu Chuan had already made almost half of the quantity.

The clarity of most of the pictures processed by Lu Chuan has been greatly improved, and can basically be used as a blacklist to compare standard pictures.

However, due to the high degree of blur in some photos, after Lu Chuan applied the data conversion method, the clarity of the photos was still not enough.

This kind of thing is difficult for a clever woman to cook without rice, and Lu Chuan has no good solution for the time being.

Separated into folders, Lu Chuan put together the particularly good pictures that he hadn't processed.

Of course, Lu Chuan didn't look at any cases these photos involved.

Anyway, most of them are large-scale fraud cases, and there are also some previous criminal cases, where the cameras captured side faces or unclear frontal portraits.

Looking at the remaining thirty or so photos, Lu Chuan took the tea from Lao Bai.

"Well, let's take a break, and they didn't say when it needs to be finished."

Lu Chuan was a little surprised at the computer configuration sent by the graphic investigation team, which was really good.

It far exceeded Lu Chuan's expectations for an office computer.

The work in the survey office is not considered busy in most cases.

As long as there is no homicide, it is basically in a state of fishing if you want to fish.

But if there is a murder case, it is normal to turn around.

In Lao Bai's words, this is not conducive to health.

Irregular life, easy to die early.

At noon, Lu Chuan didn't really want to eat in the cafeteria.

To be honest, the food in the canteen of the Criminal Investigation Detachment is pretty good.

There are three meals in the morning, noon and evening, and the most hearty at noon. There are five dishes, one soup, and two cold dishes.

But it’s not good at night. Dinner is usually the leftovers from noon.

There has never been a midnight snack before. The criminal investigation detachment's midnight snack is instant noodles.

There are various flavors of instant noodles in braised sauce, broth, chicken stewed with mushrooms, and rattan pepper.

Lu Chuan didn't catch up with the good times. He heard Lao Bai say that when there are the most instant noodles, it can fill a wall.

There is no need for it now. Under special circumstances, that is, when a major case occurs, the cafeteria is always on duty.

Although the chef on duty is unable to make a few dishes and soups due to lack of manpower, at least soaking instant noodles can turn into boiling instant noodles.

Calling Liu Guodong and the others, Lu Chuan opened his own Cayenne and ran to eat hot pot.

However, the weather in April is unpredictable.

It was still sunny in the morning, but it was cloudy and rainy in the afternoon.

Surveying the office now.

Lu Chuan swiped the photos in front of the computer, and the data flowed continuously on the screen.

After a whole morning of familiarization, Lu Chuan became more and more handy, and the speed of processing pictures increased a lot.

Lu Chuan also tried to write some plug-in software.

For example, for low-resolution photos, image and data conversion is performed directly, and data enhancement is performed automatically.

The result is no.

Because the degree of blur is different for each photo, and the blurred parts are different.

In the process of data enhancement, Lu Chuan needs to judge manually, and then choose different methods for processing.

Different methods involve different mathematical transformation formulas.

It is common to use multiple methods alternately.

Sometimes even some uncommon means such as Laplace transform and wavelet transform are used to process some independent data.

The processing process of each picture is relatively complicated, and it is very difficult to solve all problems with a plug-in.

It seems that this method cannot be widely promoted for the time being.

While Lu Chuan was swiping data on the boring computer screen, Yang Sen stood in front of the window with some melancholy.

The heavy rain became heavier and heavier, and soon blurred the vision.

"What do you think?"

Lao Bai poked Yang Sen's arm.

"It's nothing, just look at the heavy rain outside, it will be difficult if a case happens."

Ok?
After Yang Sen finished speaking, Lao Bai's expression changed.

"Crow's mouth, what case are you talking about, hurry up!"

Those who work in the police industry should be firm materialists, but sometimes things are so evil.

When there is no proposal, nothing happens.

But as long as it is mentioned inadvertently, the case will come.

Yang Sen obviously realized what he just said.

Snapped.

He slapped himself on the mouth: "Bah, bah..."

boom!
As a result, the door of the office was knocked open before the last word Bah was finished.

It's Liu Guodong.

Lao Bai and Yang Sen turned their necks stiffly, looked at Liu Guodong who was in a hurry, looked at each other, and said in unison: "Is there a case?"

Liu Guodong was slightly taken aback, he had just been notified, who told them?
"How do you know?"

Now Yang Sen can't wait to give himself another slap.

"What the hell is this called?"

Lao Bai shook his head helplessly: "Is the case serious?"

Liu Guodong nodded: "A corpse was found on the bank of the Bailan River, we have to go and have a look."

"The Bailan River?"

Yang Sen's complexion was even worse.

Why did he think of the case just now when he was looking at the heavy rain outside the window.

It is because if a case occurs on a rainy day, it is very difficult to preserve a lot of evidence.

The rain will take away most of the traces left by the murderer, and it may even bring things that do not belong to the scene.

Three years ago, a murder case occurred in Tianzhou City, which was discovered after heavy rain.

The body was found lying in a roadside gutter.

After the rainstorm, all traces of the scene were wiped away, except for a handkerchief in the pocket of the deceased.

In this day and age, who else would use a handkerchief?

Therefore, the police quickly locked a 60-year-old man in a nearby village through a handkerchief while visiting.

Because the scene of the crime was washed very clean by the heavy rain, all traces left by the murderer were erased, only a handkerchief that once belonged to the old man appeared in the pocket of the deceased.

Then, logically speaking, the old man is likely to be the murderer.

In addition, the old man and the deceased knew each other, and they were still neighbors, and they had just quarreled with each other because of the courtyard wall.

In this way, the old man naturally became the biggest suspect of the murderer.

The old man lived alone, and no one could prove whether he was at home when the deceased died.

Back then, the police had taken coercive measures against the elderly.

After all, judging from the scene, how could there be a handkerchief used by the old man in the pocket of the deceased for no reason?
But in fact, the old man's handkerchief was lost three days ago.

It was the heavy rain that washed the handkerchief that had been thrown in the gutter into the pocket of the deceased.

However, when the old man said that he lost his handkerchief, no one believed it at all.

If the murder weapon hadn't been found, the case would probably have been closed.

Later, it was the Tianzhou City Criminal Investigation Detachment who found a little blood on the rice bag in the deceased's home.

Then the murder weapon was found in the rice bag, and by collecting the fingerprints on it, it was confirmed that the murderer was the wife of the deceased.

Otherwise, the old man back then might have been wronged. (end of this chapter)
