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

According to the sanitation worker, every household in Lane 2 of Jianguo Road throws their garbage into this trash can every morning.

In other words, this trash can is where all the residents of Lane 2, Jianguo Road throw their garbage.

Nearly seven days have passed since the crime occurred, and there is nothing worth investigating around the crime scene.

As for things like footprints and fingerprints, the Dongzhou City Criminal Investigation Team had already conducted an investigation after the incident.

However, Lu Chuan did not find too much analysis and conclusions about this part in the files.

All the police officers involved in the case from the Criminal Investigation Brigade were introducing their work to the relevant personnel from the Serious Crime Unit.

Li Donglin was listening to the overall report, while Wang Song, Song Mingguang and Lu Chuan were listening to reports on related situations from other police types.

About an hour later, the serious crime team had a clear grasp of the relevant circumstances of the case and the progress of Zhou Baoguo and others in handling the case.

As for the conclusion, Zhou Baoguo and his team thought of many ways, investigated many people, and did their best to handle the case, but in fact they did not obtain many directional clues.

Inside the command vehicle, Li Donglin was convening a short meeting with members of the serious crime squad.

"The Dongzhou City Criminal Investigation Team still has relatively few clues, but they have done a lot of basic work and can provide us with some reference."

Li Donglin already had a general understanding of the basic situation at the crime scene. As for the situation of the body found at the garbage dump, he would go and take a look later.

"Please share your thoughts on this matter. We will go to the northern suburbs garbage dump to investigate again later where the body was found."

"I agree with their general judgment that since the suspect was able to put toilet paper in a black garbage bag and then threw it into this trash can, it means that he must have been here before."

This is Wang Song’s opinion.

"On the day of the incident, there were 2 people living in Lane 2 of Jianguo Road plus strangers passing through Lane 593 of Jianguo Road. My suggestion is to conduct a comprehensive investigation of these 593 people, including their call records, financial situation, interpersonal relationships, etc."

"I agree with Lao Wang's opinion."

Song Mingguang obviously meant the same thing.

Song Mingguang had heard of the Dongzhou City serial murder case before. If he only did some basic investigations, or followed the previous ideas of solving cases, then it was very likely that the case would still not be solved.

15 years have passed, and eleven cases have occurred in succession. For the first ten cases, the ministries and commissions sent experts, and many experts from the provincial department also participated in the investigation of the cases.

It can be said that many methods of handling cases have been used, but there is still no effect.

Since we are able to logically identify 593 people this time, including the suspect, then we will be able to find out the truth no matter how long it takes by tracking and investigating these 593 people.

Li Donglin nodded in agreement with Song Mingguang and Wang Song's ideas. Although Zhou Baoguo and his team had not identified the suspect and had not found any directional clues, at least the occurrence of this case had narrowed the number of suspects to 593 people.

Li Donglin was even thinking about which of these 593 people might have appeared at the North Suburbs garbage dump. If a differential screening was done, it might be possible to further narrow down the scope of the suspects.

Sometimes solving a case is like this. Although the clues do not point to anyone committing a crime and the suspect did not leave any obvious traces at the scene, if through spatial screening, two consecutive related spaces confirm that a certain person appears here, then that person must be a strong suspect.

After asking for other people's opinions, Li Donglin looked at Lu Chuan. "Director Lu, what do you think?"

Everyone knows that Lu Chuan has been promoted to deputy director of the branch, so no one calls him Xiao Lu or Captain Lu anymore, but calls Da Hu Director Lu.

"Director Li, please don't call me that. It would be better to call me Xiao Lu or Lu Chuan."

Regarding the scope of investigation into the criminal suspect, Lu Chuan actually did not have many other opinions.

The situation he had just investigated at the crime scene focused on analyzing from the perspective of on-site investigation technology.

"Director Li, I want that garbage bag."

Lu Chuan looked serious.

"The severed finger was found in the garbage bag, which means that the suspect must have come into contact with it. In addition, I would like to see if I can do some trace evidence analysis based on the contents of the black plastic bag to identify the person to whom the black plastic bag belonged."

Zhuchuan’s idea was actually very simple. Although it was difficult to determine who threw the black plastic bag into the trash can based on the surrounding situation, there were other garbage in the black plastic bag besides broken paper.

Lu Chuan did not see a detailed description of what was inside the black plastic bag in the file, so he had to personally identify and analyze the black plastic bag.

"Okay, that's no problem. I'll tell Zhou Baoguo later and they will give you their full support."

"What about other aspects?"

Lu Chuan shook his head.

The provincial department has already issued a notice on these cases, and all resources will be allocated to the serious crime team. If there are any needs, they will be met immediately.

The resources Wu Chuan needs are actually technical support, such as the identification and analysis of trace evidence, which he might have had to do himself in the past.

But this time the technical support will be provided by the provincial technical center, so relatively speaking his workload is not particularly large. In addition, he can also make more assumptions to support his judgment.

"Okay, in that case, let's conduct the investigation according to our respective arrangements. Later, we will go to the northern suburbs garbage dump to see the situation of the body found there."

After Li Donglin made the relevant arrangements, the members of the serious crime team also communicated with the relevant criminal police from the Dengzhou City Criminal Investigation Detachment.

After completing the communication and deployment, all members of the serious crime team drove to the second crime scene.

North Suburbs Landfill.

The body was found in a landfill in the northern suburbs. The garbage here is dumped in the open air. Every time the garbage is dumped, many people come to sort out some useful garbage.

The victim's body was found at the bottom of the garbage pit by one of the scavengers.

At the crime scene, Zhou Baoguo continued to introduce the findings and some basic conclusions of the Dongzhou City Criminal Investigation Brigade. (End of this chapter)
