Being able to participate in the task force set up by the provincial department is very helpful for Lu Chuan's future promotion.

Even if you don't look at these extremely long-term interests, being able to communicate with experts from the provincial department is also a recognition of Lu Chuan's professional skills.

Lao Bai and Yang Sen picked up the soft China with the prefix of 3 and began to teach Lu Chuan the opportunity.

"When you get to the task force, you have to listen more and watch more and talk less."

"Lao Bai is right, but talking less doesn't mean doing more, the main thing is to listen more and watch more."

Yang Sen obviously agreed with Lao Bai's point of view, spit out a fist-sized smoke ring, and continued: "This kind of task force is usually formed by provincial departments. ”

"I just asked Ren Qiang to inquire."

Ren Qiang's daughter is in the office of the city bureau, a well-informed group.

"The commander of the provincial department is Li Donglin, director of the Second Criminal Investigation Division, who was originally a trace inspection expert of the Tianzhou City Criminal Investigation Detachment, and went there five years ago when he was engaged in a public direct election competition."

The public is directly elected, and Lu Chuan knows this way of selecting cadres.

Different from the general organizational allocation, the public direct election is actually an exam, for a certain position, after delineating some hard conditions, everyone in the system can register.

Then, after a written test, interview, and expert voting, the final candidate is determined.

"Director Li is from a trace inspection background, and attaches great importance to the logic, technology and evidence of solving the case."

Liu Guodong nodded beside him: "Xiao Lu, you have to study hard with Director Li when you go." ”

"He is a top expert in fingerprint identification in the provincial department, and he can be ranked first in the country, and often participates in fingerprint battles organized by ministries and commissions."

Li Donglin's name, as the director, Lu Chuan really doesn't know.

But as a fingerprint identification expert, Lu Chuan had heard of him.

The first person in the provincial department of forensic medicine is Zhang Yuanchao, and the first person in fingerprint identification and analysis is Li Donglin.

Based on the deeds he had heard before, Lu Chuan could basically judge that Li Donglin's fingerprint identification and analysis ability should be stronger than the intermediate fingerprint identification and analysis skills he mastered.

But now that Lu Chuan's fingerprint identification analysis has been upgraded to an advanced level, maybe he can surpass the other party, right?

"The provincial department attaches great importance to the case of Song Kun's murder this time, in addition to our criminal investigation, there are also experts involved in the economic investigation, this time you have to make more friends and communicate with everyone."

"When you work for a long time, you will know how beneficial it is to know more people."

The kung fu of the two of them in this meeting can be regarded as a thorough summary of their past life work experience and instilled it in Lu Chuan.

"Alright, let's go eat first."

Afternoon.

At the gate of the office building of the city bureau, a row of more than 20 people stood on the steps, all of them in good spirits and straight police uniforms.

This is not a group photo, but to greet the leaders of the provincial department.

Song Jiangguo and Wang Kai led the team, followed by the heads of relevant departments, as well as Lu Chuan and other members recommended by the city bureau to join the task force.

Although he is a provincial general, he only selected a few heavyweights who must join.

Trash fish for miscellaneous work can be recommended by the city bureau.

It can't be said that it is unfortunate, Lu Chuan is not in the list of generals, but he has entered the trash fish sequence.

Don't underestimate this trash fish sequence, ordinary people can't get in if they want to.

The afternoon sun was not dazzling, and Lu Chuan stood at the edge of the greeting procession, watching a police car slowly drive into the gate of the courtyard of the city bureau.

The security guard standing guard at the door saluted, standard, solemn, and solemn.

That spirit, Lu Chuan was a little ashamed to see it, his salute was not as good as other people's standards.

The criminal investigation detachment does not have this kind of honor guard, and it is good for the old man in the mailroom at the door to see people coming in.

In fact, the security on the side of the city bureau is only real security.

It's just that they are generally recruited veterans, and their military quality is higher.

Don't wonder why veterans have to work as security guards, and working as a security guard in a city bureau has a much better chance of becoming an auxiliary police officer, and most of them don't have to go out on duty.

After all, there are still few cases directly handled by the municipal bureau, and if there is work, it is basically done by the sub-bureau, criminal investigation detachment, economic investigation detachment or criminal police brigade below.

Although Lu Chuan is not very clear about this matter, he also knows a rough idea.

"Lee! Welcome, welcome! ”

Song Jiangguo was pulling the car door and shaking hands warmly, and Wang Kai followed by his side: "Li Chu, welcome!" ”

In terms of level, Li Donglin and Song Jiangguo are at the same level, and even in terms of the scope of management, Li Donglin is only engaged in technology, while Song Jiangguo is engaged in all-round.

And Song Jiangguo's appointment has nothing to do with the provincial department, he is from the city.

The vertical management of the public security system refers to the business, not the personnel.

Therefore, Song Jiangguo's posture and welcoming Li Donglin with more than 20 people is very good for him and the provincial department.

"Song Ju, you're polite, I'm going to trouble you this time."

Although Li Donglin is a technical expert, he has been cultivated in the provincial department for so many years, and he is no stranger to the sophistication of human feelings.

"What did Li say, please, let's report the situation first."

"Okay, Song Bureau, Wang Bureau, please."

The bigwigs entered the office building, and Lu Chuan and others followed.

In the conference room, Wang Kai personally introduced the investigation process of the case.

"The details of Song Kun's murder have all been clarified, and one of the suspects has also been arrested."

Li Donglin nodded: "After your situation was reported, the department attached great importance to it and arranged for the BZ City Public Security Bureau to carry out the arrest work as soon as possible." ”

According to Wang Manli's confession, the killing of Song Kun was planned by her boyfriend Chen Gang.

Wang Manli was just in charge of waiting for him in the ravine of Xinjian Village and driving him away.

As for stealing cars, choosing the point of impact, causing accidents, etc., she was not involved.

So the details of Song Kun's death are not very clear.

As for the tire tracks that Lu Chuan found at the scene of the crime, the car with narrow front wheels and wide rear wheels was indeed the means of transportation they took to leave the scene.

The reason why the traffic police have not found it is because the car belongs to Chen Gang and is located in Binzhou, and Chen Gang drove the car away after the incident.

"This Chen Gang is an important person," Li Donglin raised his hand to look at his watch: "At this time, the arrest over there should have begun...... Xiao Zhang. ”

A capable young man who came with Li Donglin nodded, opened the laptop he was carrying, and connected to the projection screen of the conference table.

A shaky image appears on the screen.

"This is the police cloud platform, and after the provincial department expands the server, it is now able to watch remotely and in real time."

"This is the scene of the arrest in Binzhou."

Including Song Jiangguo, most of them had no accidents.

This thing has been done before, but it turns out that due to hardware and network transmission, it can't be tracked in real time, and only video can be recorded.

The current police cloud platform finally realized the province's networking last month.

Because Lu Chuan is not a front-line criminal policeman, he is not particularly familiar with this, and he is a little curious to look at the picture on the projection screen.

Although he was curious, but he kept in mind what Lao Bai taught, the principle of listening more and watching more, and talking less, Lu Chuan did not squeak.

"Determine the location of the suspect, one group, two groups are ready for action!"
