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

These cases are not that different from the vast majority of cases.

The suspects Li Baowei and Qin Xiaohui were actually already in the police's sight from the very beginning.

Although they were not in the police's sight as criminal suspects, the police had contact with both of them during the investigation.

It's just that when the QZ City Criminal Investigation Detachment was handling the case, there wasn't much direct evidence, so they didn't doubt whether the two people were involved in the case.

Even after the serious crime squad got involved and discovered that Li Baowei was a suspect, they almost missed him because he had an alibi.

As for Qin Xiaohui, it was just the opposite. During the entire investigation process of the case, she provided a lot of information about Wang Jingya.

Especially about Wang Jingya's interpersonal relationships, why he left on the day he disappeared, who he met, etc., etc., all this information was actually provided by Qin Xiaohui.

Judging from the current emotional results, the other party is actually trying to disrupt the police's vision deliberately.

However, the law has long arms and legs. In order to evade investigation and avoid suspicion, Qin Xiaohui deliberately invited Wang Jingya to dinner on the day of the crime, but then followed him to the neighborhood where Chen Yang lived.

Qin Xiaohui originally thought that this matter would not be discovered, but she did not expect that the police would be able to screen the vehicles passing by the intersection.

Combined with the incomplete fingerprint Lu Chuan found at the crime scene, he finally identified Qin Xiaohui.

"Director Li, thanks to the serious crime squad, otherwise... this case would probably not be solved."

After everyone had reported, the case was basically settled, and the task of the serious crime team was basically completed. The remaining work was to be done by the CZ City Criminal Investigation Detachment, which was all basic material work.

As the captain of Tianzhou City Criminal Investigation Detachment, Wang Chuanmin expressed his gratitude to Li Donglin.

In fact, this case seems to have a lot of details, and the Tianzhou City Criminal Investigation Detachment also noticed them, but the most critical points were actually discovered after the serious crime team arrived.

For example, regarding on-site investigation.

Qin Chuan's second on-site investigation discovered extremely important clues, bloodstains and fingerprints.

Although the incomplete fingerprint could not be matched to the target person in the system, when Qin Xiaohui and Li Baowei came into the police's suspicion, the incomplete fingerprint became the key evidence to lock on to the other party.

This is also one of the most important pieces of evidence left by the suspect at the crime scene and the most important key link in the entire closed loop of the chain of evidence.

Through bloodstain identification, Qin Xiaohui and Li Baowei were cross-identified.

Because the blood type of the bloodstain is different from Qin Xiaohui's, but the same as Li Baowei's.

The fingerprints belonged to Qin Xiaohui, which meant that there were not one but two people at the crime scene.

With these evidences, it was easy to break through Qin Xiaohui and Li Baowei during the interrogation process.

In addition, the two groups of Wang Song and Song Mingguang also made great progress.

Li Baowei came into the police's sight during this investigation.

"Captain Zhang, you're too polite. The duty of the serious crime squad is to handle major cases."

Li Donglin didn't think it was a big deal.

In the past, when Li Donglin, as the director of the Criminal Investigation Division of the Provincial Department, was involved in major cases, he was mostly in the supervisory role.

Before the establishment of the Provincial Department's Major Crimes Unit, the specific cases were generally handled by the Criminal Investigation Brigade. Even in the Municipal Public Security Bureau, the so-called special case team was a temporary organization formed by transferring people from the lower levels.

The municipal bureau and provincial department do not investigate specific cases, they only supervise specific cases.

Or provide some experts to help.

The most important investigative force is actually the criminal police brigade or criminal investigation detachment in each county and city.

The serious crime team formed by the provincial department brought together the province's most outstanding experts in this field to directly participate in the investigation and handling of cases. With the full support of the public security bureaus in various cities and counties, Anjian had the technical and material foundation to make rapid breakthroughs.

Li Donglin and his team were the first to launch this mechanism, and various provinces have been promoting it since last year. Now, the entire country has basically been covered, and the provincial department's serious crime squad is basically standard in every province.

"Director Li is too polite. This case may be an ordinary case for the serious crime team, but it is really difficult for our detachment to handle."

"Well, let's have dinner with the serious crime team members at the director's place tonight. Director Li, what do you think..."

With Li Donglin's status, he would be respected by the top leaders of various municipal bureaus wherever he went. What's more, Li Donglin himself came from Tianzhou City and was familiar with the directors and some leadership teams here.

It’s just that when Li Donglin was released, he left as a technical criminal policeman. On the contrary, he never held any important position in the CZ City Public Security Bureau.

I am quite familiar with the serious crime squad in Tianzhou City and have taken over two cases here.

This is especially true for Lu Chuan, who is quite familiar with Tianzhou City. Tianzhou City and Haizhou City are adjacent neighbors. Lu Chuan had come to Tianzhou City to handle cases when he started working as a policeman.

So, I know a lot of people.

The case had been solved, so everyone had a drink at the dinner, but not much.

The director of Tianzhou City, along with the political commissar and three deputy directors, will attend today's dinner.

This lineup can be said to be quite important.

Of course, in this kind of situation, most of what people say are just polite words.

The director of Tianzhou City expressed his gratitude to Li Donglin on behalf of the Tianzhou City Public Security Bureau, and thanked the provincial department for its support for the development of the TZ City Public Security Bureau over the years.

Li Donglin felt the same way, thanking the Tianzhou Municipal Public Security Bureau for providing a lot of talents to the provincial department over the years.

It was already past midnight when we finished the meal.

Two nights ago, Lu Chuan and his team were all in the Criminal Investigation Brigade office or the conference room, just taking a short rest.

Even Wang Song and his friends were always running outside, and they would only take a nap in the car during their breaks.

The Tianzhou City Public Security Bureau has arranged a guesthouse for me tonight, so I can finally have a good sleep in bed.

Lu Chuan returned to Haizhou City early the next morning.

The case had been solved, so there was naturally no need to stay. After saying goodbye to his colleagues in the serious crime team and Li Donglin, Lu Chuan was the first to leave.

Although nothing has happened in Haizhou City recently, Lu Chuan just got married a few days ago, and now it's like a new marriage after a short separation.

After returning home, it was the weekend. After two days of rest, Lu Chuan came to the High-tech Zone Criminal Police Brigade on Monday in high spirits. (End of this chapter)
