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

Li Donglin was very satisfied with Deputy Director Qin's attitude. The Qingzhou Municipal Public Security Bureau handled this point well.

Taking a deep breath, Li Donglin was highly focused. Although this case was quite big, he couldn't be hasty in handling it. Five days was neither long nor short.

The most important thing in a case like this is to find clues about the suspect in such a tight situation. As long as the suspect's identity is confirmed, the rest is just a matter of finding and arresting him.

Li Donglin turned and looked at Lu Chuan.

"Lu Chuan, I'm going to hand it over to you. I don't ask you to be fast, but you must investigate carefully and not miss any relevant details. In addition, if the identity of the suspect can be confirmed during the on-site investigation, that would be great. However, the remaining matter is to track and capture these people. It's not difficult for us. Do you understand what I mean?"

Lu Chuan nodded.

When he first joined the serious crime squad two years ago, he was still a young man who could only do some technical work, but now Lu Chuan is already the deputy director of a district or county bureau in charge of criminal investigation.

In addition to technical work, he also has other skills in controlling the overall situation, and his overall arrangements in the process of solving some cases are much better than before.

After receiving the task, Lu Chuan made relevant preparations immediately and conducted a second on-site inspection of the Dongfang construction site.

After Lu Chuan received the task, Li Donglin began to assign work to other people.

"Song Mingguang, you lead a team to investigate the surrounding surveillance and all the witnesses to see if you can draw a portrait of the suspect or find some video footage of the suspect to confirm the suspect's identity."

"Luo Qiang, you guys are responsible for coordinating with the Qingzhou Public Security Bureau. You must ensure that all entrances and exits are closed and under martial law. Do not allow criminal suspects to leave Qingzhou with weapons."

"Yes!"

After receiving the order, personnel from all parties began to work non-stop.

Lu Chuan started to check some of his own equipment. When he came from the provincial department, he had already brought some things with him, but they were not complete. So he communicated with the criminal investigation detachment leader Zheng Baode and asked the staff from the on-site survey office to come together.

"Hello, Director Lu. My name is Qin Jun. I am the director of the Health Office of the Criminal Investigation Brigade of the Qingzhou Public Security Bureau. After the incident, we went to the scene to investigate. I will give you a brief report on the relevant situation."

After the incident happened yesterday, in order to quickly find the suspect, the Qingzhou City police conducted an on-site investigation and also checked all the surveillance data in the construction site.

Lu Chuan nodded at the information in this regard. He had not seen the most detailed version, so if the other party could give a detailed introduction, coupled with his own investigation and verification, he would be able to find some clues.

"The surveillance camera at the construction site captured the suspect, but he was wearing a hood and a hat, and his entire body was covered up, so it was impossible to see any of his physical features."

As he spoke, he opened his phone and computer early this morning and played all the surveillance photos and clips he had reviewed for Lu Chuan to watch.

Sure enough, the high-definition camera inside the construction site could clearly see the other party’s route last night.

Because there were workers at the construction site at night and they were also investigating the case, the gate was not locked. After the suspect came in, he attacked the workers at the construction site without any hesitation. "Homemade weapons?"

The footage in the picture is very clear, and you can see that the weapon used by the other party is not a homemade weapon. Lu Chuan recognized at a glance that it was a homemade weapon.

Qin Jun nodded: "Indeed, the weapons used by the other party are homemade weapons, but the bullets used are ordinary Type 54 weapons. We have already analyzed the ballistics."

Otherwise, staring at the screen and doing ballistic analysis at this time is basically of no use. Since it is a homemade weapon, it is impossible to find its origin.

It is not possible to identify the opponent from his weapon, but if the opponent is strong and has self-control, then it is still worth analyzing for related professions.

If the other party is using homemade weapons, there are only two ways to get them. The first is to buy them on the black market, and the second is to make them yourself.

If it is the first case, the other party purchased the weapon, then it is very likely that by tracing the source of the weapon, it is possible to find the other party's understanding and related information, but if the weapon is made by the suspect himself, then it is difficult to find the other party through the weapon.

It is initially suspected that the weapon was most likely purchased, because if the other party can make their own weapons, then the possibility of homemade weapons of mass destruction is also relatively high, so there is no need for the other party to take the risk of committing a crime at the construction site.

Of course, the specific situation is just a guess. Whether this is the case or not depends on the conclusions of subsequent investigations.

The most important thing at the moment is to determine the identity of the other party based on the currently known clues and intelligence. As long as the identity of the suspect can be confirmed, the rest will be easy.

Lu Chuan first watched the entire process of the suspect committing the crime.

Most of the workers at the construction site got off work at 5:30 last night. At 6:00, some overtime workers also left the construction site, leaving only two manual labor sites.

There are a total of 25 regular staff members at the Oriental construction site, and 32 additional staff members.

The entire Oriental construction site is not located in the city center, but in a slightly remote place close to the suburbs. However, the surrounding transportation is relatively developed, including subways and buses, and it is also close to a highway. If the criminal suspect commits the crime and then flees after robbing the weapon, to be honest, it is very likely that he will leave Qingzhou City directly.

Although the Qingzhou City police acted very quickly last night.

The suspect was at 6:32. He was seen on surveillance video entering the construction site room from the main gate and smashing the other person's head, killing him instantly.

After that, the other party did not leave the construction site room.

He first took the access card from the body of the construction worker, and then pushed the door on the right and entered the building.

Because if you want to enter the normal office building of the construction site from the construction site room, you need to swipe the access control to enter, after all, it is not open to the public.

The opponent's movements were so smooth that Lu Chuan's scalp was numb. (End of this chapter)
