"Section Chief Yu, don't polite me. If you have any advice, just say it." Chu Nan said quickly.

"Hahaha, Team Leader Chu, don't be humble. Our industry is not about seniority!

When three people walk, I will be my teacher. If you have real skills, I can learn from you, then you will be my teacher.

Of course, I am a little older and you will definitely not be able to accept this.

In this way, if you don’t dislike it, we will be friends with you forgetting our age and make friends.

I'm not polite to you. If I encounter any problems, I'm not allowed to disturb you." Section Chief Yu said with a smile.

This is really a technical maniac, he doesn't pay attention to his identity at all.

Can you say this in front of so many leaders?

His original intention was good, but he really put Chu Nan on the fire, making him feel a little embarrassed.

Zhou Chu, who was standing aside, saw Chu Nan's predicament at first sight and quickly said with a smile: "Yes, yes, Section Chief Yu is right. Our industry is not prosperous and we are considering seniority.

Our Nanjiang criminal psychology Taishan Beidou is a friend of the rising stars. This is a beautiful story in our domestic criminal investigation industry.

Dear leaders, Team Leader Chu asked us to come for the case. Let's talk about these close words in the future."

"Yes, the case is preferred. Team Leader Chu, what new discoveries have you made?" Director Fang asked.

Chu Nan nodded, "I happened to find a witness near the crime scene.

According to the witnesses, he encountered a weird man near the crime scene at around 1:20 last night.

The guy didn't hold an umbrella or a raincoat, and just squatted around the corner near the crime scene.

According to forensic identification, the victim's death time was around 11:30, and the time was just right.

At that time, the witness had a brief conversation with the suspect. According to the witness's description, of course, it was raining heavily, and the street lights were not very sufficient, and the suspect's appearance was not seen.

However, it is certain that the suspect was relatively large and was very unstable at the time. He spoke Mandarin, but Mandarin was not very standard.

I guess the suspect was deliberately speaking Mandarin to confuse the situation.

Also, when witnesses passed by the suspect, they smelled a strong smell of engine oil.

The rag we found at the crime scene extracted the components of the engine oil, which can be basically confirmed that the suspect had been exposed to the engine oil before committing the crime."

Director Fang shook his head with a frown, "Team Leader Chu, this can't be considered evidence, right?

We cannot be sure whether the rag was left behind by the suspect, or even at all, when the rag was left at the crime scene.

If we follow this clue, if our judgment is wrong, it will waste a lot of manpower and material resources.

Now is the critical period for solving this case. If the investigation direction is wrong, the difficulty of solving this case will increase in geometry."

Chu Nan nodded, "Director Fang, what you said makes sense. At this critical moment, the cost of trial and error is too high.

However, this link of evidence is complete. In addition to the rag, witnesses can also confirm that when he saw the suspect, he smelled the smell of engine oil.

We also found cigarette butts with fingerprints on the scene, but the fingerprints were artificially damaged.

Moreover, the owner of these cigarette butts has not left DNA on the cigarette butts.

It is understandable that a certain coincidence appears, but it shouldn't be a coincidence if so many coincidences appear at the same time.

I think we should separate a group of people and follow this clue to check. Even if the direction is wrong, it will not affect the general direction."

Captain Wang nodded, "Yes, you can try to check this clue, as long as it does not affect the general direction.

In this way, Team Leader Chu, you have discovered this clue, so you are responsible for continuing to investigate.

As for the manpower, it is very tight now, so you can take your comrades from Linchuan City to follow this clue first.

When you need support, you should contact Director Zhou again, so that it will not have much impact on the normal direction of the case."

"Okay." Chu Nan nodded.

Section Chief Yu asked tentatively: "Captain Chu, are you suspicious that the murderer is engaged in the auto repair industry?"

"If you have this possibility, it is not ruled out that you are a big car driver or a similar practitioner." Chu Nan replied.

Section Chief Yu nodded, "It's possible, but this range is too large.

Baicheng City is our manufacturing base in Nanjiang Province. The most common ones here are large trucks. Naturally, the repair shops are several times more than other county towns.

To find a suspect from such a large range is like finding a needle in a haystack.”

At present, the safest way is to continue to look for witnesses and continue to check the surrounding surveillance, and start with Sihai Labor Service Company.

After all, there is no evidence and no witnesses. You don’t even know the appearance of the murderer. How do you check it?

Even if the murderer is really engaged in the auto repair industry or a big car driver, as Chu Nan guessed.

So what can it be?

How did you find this person out of tens of thousands of people?

Isn't there any evidence?

In most people's opinion, what Chu Nan is doing now is really eager for quick success and is taken for granted.

In other words, his approach is simply to try to hit a dead mouse.

"Try it, this is just one direction." Chu Nan smiled faintly.

Section Chief Yu looked at Chu Nan with a complicated expression, nodded and said, "Yes, this direction is quite reliable, try it."

"It's good to be hardworking young, but sometimes, if you want to fight, you have to find a good direction first.

If the direction is wrong, no matter how dare you fight, you will be a headless fly.

But I can understand, are you young? I have handled some cases and gained some honors before. If I were to do it, I would feel good about myself.

Sometimes, it is a good thing to suffer a little setback when you are young, and it is much better than making mistakes in the future." When Chu Chunan left, Team Wang said with a smile.

Section Chief Yu immediately frowned, stared at Team Wang and asked, "Mayor Wang, what you said is a bit too full, right?

In handling criminal cases, the most important thing is to combine observation, reasoning and action.

Team Leader Chu has good observation and reasoning skills, and his execution ability is obvious to all.

Team Leader Chu has been working for half a year and has solved major cases in a row, which can fully prove his ability.

Sometimes, when handling a case, you have to break your mind a little.

It is good to play steadily, but the method of playing steadily is often not applicable.

For example, the case in front of me, Director Zhou and others' preliminary investigation work was carefully enough, right? Did the preliminary work be done solidly enough?

What's the result?

The murderer was still committing the crime unscrupulously! When we were prepared, we killed another person."

Section Chief Yu said this, and Mr. Zhou Chu's face turned red, and he wished he could dig a hole with his hands on the spot and bury himself.
