There is actually not much difference between these cases and the vast majority of cases.
The criminal suspects Li Baowei and Qin Xiaohui were actually on the radar of the police from the beginning.
Although he was not brought into the police's sight as a criminal suspect, during the investigation and interviews, the police had contact with these two people.
It’s just that when the QZ City Criminal Investigation Detachment was handling the case, because there was not much direct evidence, there was no doubt about whether the two people were involved in the case.
Even after the crime team got involved and found out that Li Baowei might be suspicious, they almost missed him because he had an alibi.
As for Qin Xiaohui, it was just the opposite. During the entire investigation of the case, she provided a lot of information about Wang Jingya.
Especially about Wang Jingya’s interpersonal relationships, and why he left to see who he met on the day he disappeared, etc. Wait, this information was actually provided by Qin Xiaohui.
Judging from the current emotional outcome, the other party actually deliberately wanted to disrupt the police's sight.
However, Skynet was very careful and careful. In order to avoid investigation and avoid suspicion, Qin Xiaohui deliberately invited Wang Jingya to dinner that day, but then followed him to the neighborhood where Chenyang lived.
Qin Xiaohui thought that this matter would not be discovered, but she did not expect that the police could screen the vehicles passing by at the intersection.
Coupled with the broken fingerprint that Lu Chuan found at the crime scene, Qin Xiaohui was finally identified.
"Director Li, thanks to the serious crime team, otherwise... this case probably would not have been solved."
After everyone reported, the case was basically almost over. The task of the case team has basically been completed, and the remaining work, which is performed by the CZ City Criminal Investigation Detachment, is some basic material work.
Wang Chuanmin, as the captain of Tianzhou City Criminal Investigation Detachment, expressed his gratitude to Li Donglin.
In fact, this case seems to have many details, and the Tianzhou City Criminal Investigation Detachment has also noticed them, but the most critical points were actually discovered only after the crime team arrived.
For example, regarding on-site inspection.
Qinchuan’s second on-site investigation found extremely important clues, blood stains and fingerprints.
Although the broken fingerprint could not be compared to the target person in the system, when Qin Xiaohui and Li Baowei entered the suspicious sight of the police, the broken fingerprint became the key evidence to lock the other party.
This is also one of the most important pieces of evidence left by the criminal suspect at the crime scene, and is the most important key link in the closed loop of the entire evidence chain.
Through the identification of blood stains, Qin Xiaohui and Li Baowei were cross-locked.
Because the blood type of the blood stain is different from that of Qin Xiaohui, but the same as that of Li Baowei.
The fingerprint belongs to Qin Xiaohui, which means that the person at the crime scene was not one person, but two people.
With this evidence, it is logical to break through Qin Xiaohui and Li Baowei during the interrogation process.
In addition, the two groups Wang Song and Song Mingguang have also made great progress.
It was during this investigation that Li Baowei came into the police's sight.
"Detachment Zhang is too polite. The duty of the crime squad is to handle major and important cases."
Li Donglin thought it was nothing.
In the past, as the director of the Provincial Criminal Investigation Division, Li Donglin actually focused more on supervising the handling of major and important cases.
Before the serious crime team of the provincial department was established, the actual handling of cases was generally at the level of the criminal investigation detachment. Even in the Municipal Public Security Bureau, the so-called task force is a temporary organization established by transferring people from below.
Municipal bureaus and provincial departments do not investigate specific cases, but 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 of each county and city.
The serious crime team established by the provincial department brings together the most powerful experts in this field in the province to directly participate in the investigation of the case. Coupled with the full support of the local public security bureaus, this is the case. It has established the technical and material foundation for Anjian to make rapid breakthroughs.
Li Donglin and others were the first to launch this mechanism. Since last year, all provinces have also launched it. Now, it is basically covered across the country. The serious crime teams of provincial departments are basically the standard for each province. match.
"Chief Li is too polite. This case may be an ordinary case for the serious crime team, but for our detachment, it is really difficult to handle."
"In this way, the director will give details to the comrades from the serious crime team tonight. Let's have a meal, Li Chu, you see..."
As Li Donglin, wherever he goes, he will be paid attention to by the leaders of each municipal bureau, not to mention that Li Donglin himself came from Tianzhou City, and this The bureau chief and some leadership teams are familiar with it.
It’s just that when Li Donglin went out, he was a technical criminal policeman. No, on the contrary, he did not hold any important position in the CZ City Public Security Bureau.
I am quite familiar with the serious crime team in Tianzhou City. I have taken over two cases here.
This is especially true for Lu Chuan, who is quite familiar with Tianzhou City. Originally, Tianzhou City and Haizhou City were neighbors, and Lu Chuan had come to Tianzhou City to handle cases when he was working as a police officer.
So, I know a lot of people.
The case has been solved, so everyone had a drink at the dinner, but not too much.
The director of Tianzhou City brought the political commissar and three deputy directors to attend today's dinner.
This lineup can be said to be taken seriously.
Of course, in this kind of situation, most of what people say is just for the occasion.
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.
The same is true for Li Donglin, who is grateful to the Tianzhou Municipal Public Security Bureau for providing many talents to the provincial department over the years.
It was already past twelve o'clock in the evening after finishing the meal.
For the past two nights, Lu Chuan and the others were in the criminal investigation detachment office or in the conference room, casually resting for a while.
Even Wang Song and the others were running outside all the time, and they would just relax in the car for a while during their breaks.
The Tianzhou City Public Security Bureau has arranged a guest house tonight, and I can finally sleep in the bed.
Lu Chuan returned to Haizhou City early in the morning on the second day.
The case has been solved, so there is no need to stay any longer. After greeting his colleagues in the crime team and Li Donglin, Lu Chuan was the first to leave.
Although there have been no answers recently in Haizhou City, Lu Chuan has just been married a few days ago, and now it is better to say goodbye than newlyweds.
After returning home, just in time for 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)
