According to the sanitation workers, every household in Alley 2 of Jianguo Road throws garbage into this trash can every morning.
In other words, this trash can is where all the residents of Jianguo Road 2nd Lane throw their garbage.
Nearly seven days have passed since the incident, and there is nothing of value for exploration around the crime scene.
As for the footprints and fingerprints, the Dongzhou City Criminal Investigation Detachment had already investigated them after the incident.
But Lu Chuan did not find too many analyzes and conclusions about this part in the dossier.
The police officers involved in the criminal investigation detachment were all introducing their work to the relevant personnel of the serious crime team.
Li Donglin was listening to the overall report, Wang Song, Song Mingguang, including Lu Chuan, were listening to reports on the relevant situations of their other police types.
About an hour later, the relevant circumstances of the case and the progress of Zhou Baoguo and others' handling of the case were probably understood by the serious crime team.
As for the conclusion, Zhou Baoguo and the others thought of many ways, checked many people, and did their best to handle the case, but in fact they did not obtain too many directional clues.
In the command vehicle, Li Donglin was convening members of the serious crime team for a short meeting.
"There are still relatively few clues from the Dongzhou City Criminal Investigation Detachment, but they have done a lot of basic work and can provide us with some reference."
Li Donglin already has a general understanding of the crime scene The basic situation, as for the situation of the bodies found in the garbage dump, we have to go there later to see.
"Let us know what you think about this situation first. Later we will go to the northern suburbs garbage dump where the body was found to investigate again."
" I agree with their general judgment. Since the suspect was able to put the toilet paper in a black garbage bag and throw it into this trash can, it means that the other party must have been here."
This is Wang Song’s opinion.
"On the day of the incident, there were 593 people living in Jianguo Road Lane 2 plus strangers who passed through Jianguo Road Lane 2. My suggestion is to conduct a comprehensive investigation of these 593 people, including investigating their call records and financial status. , interpersonal relationships and other comprehensive investigations.”
“I agree with Lao Wang’s opinion”
Song Mingguang obviously means the same.
Song Mingguang has heard about the Dongzhou City serial murder case before. If he only does some basic investigations or follows the previous ideas for solving the case, then it is very likely that this case will still not be solved.
Fifteen years have passed, and eleven cases have occurred in the meantime. For the first 10 cases, the ministries and commissions sent experts to the provincial department, and many experts participated in the investigation process of the cases.
It can be said that many case-handling methods have been used, but still have no effect.
Since 593 people can be logically identified this time, including criminal suspects, then by tracking and investigating these 593 people, no matter how long it takes, we will definitely be able to find out what happened.
Li Donglin also nodded in agreement with Song Mingguang and Wang Song's ideas. Although Zhou Baoguo and the others did not lock in the suspect and found no directional clues, at least the occurrence of this case has identified the suspect. 593 people were targeted.
Even Li Donglin is still thinking about which of the 593 people may appear in the northern suburbs garbage dump. If a differential screening is done, it may further narrow the scope of suspects
Some This is how the case was solved. Although the clues did not point to anyone committing the crime and the suspect did not leave any obvious traces at the scene, through spatial screening, two consecutive related spaces confirmed that someone appeared here. If so, then the other party must be highly suspicious.
After soliciting other people's opinions, Li Donglin looked at Lu Chuan. "Bureau Lu, what do you think?"
Everyone knows that Lu Chuan has been promoted to deputy director of the branch, so they no longer call him Xiao Lu or Lu Team, they all call Dahu the land bureau.
"Li Chu, please don't call me that. It would be better to call me Xiao Lu or Lu Chuan."
As for the scope of the investigation of the criminal suspect, Lu Chuan has not actually had any experience with it. Many other opinions.
The situation he had just investigated at the crime scene was mainly analyzed from the perspective of on-the-spot investigation technology.
“Li Chu, I want that garbage bag.”
Lu Chuan looked solemn.
“The severed finger appears in the garbage bag, which means that the severed finger must have been in contact with the criminal suspect. In addition, I want to see if I can do some trace evidence analysis based on the contents of the black plastic bag to locate it. The person who belongs to this black plastic bag”
Zhu Chuan’s idea is actually very simple. Although it is difficult to determine who threw this black plastic bag into the trash can from the surrounding situation, but this black plastic bag In addition to broken paper, there are other garbage inside the plastic bag.
Lu Chuan did not see a detailed description of what was inside the black plastic bag in the file, so he had to conduct an identification and analysis of the black plastic bag himself.
"Okay, there is no problem with this. I will tell Zhou Baoguo later and they will give you full support."
"What about other aspects?"
Lu Chuan Shake his head.
The provincial department has issued a notice regarding these cases, and all resources will be directed to the serious crime team. If there are any needs, they will be met immediately.
The resources Wu Chuan needs here are actually technical support, such as identification and analysis of trace evidence. In the past, he might have had to do it himself.
But this time, the provincial technical center will provide technical support, so relatively speaking, his workload is not particularly heavy. In addition, he can also make more assumptions to support his judgment.
"Okay, if that's the case, let's go and investigate first according to everyone's own arrangements. Later, we will go to the northern suburbs garbage dump to see the situation of the bodies found there."
After Li Donglin completed relevant arrangements, the members of the serious crime team also conducted relevant communications 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 took a bus to the scene of the second crime.
Northern suburbs garbage dump.
The place where the body was found is located in the Yishu landfill of the northern suburbs garbage dump. The landfill here is done in the open air. Every time the garbage is cleared, many people come to sort out some useful items. Rubbish.
The victim's body was discovered by one of the scavengers at the bottom of the garbage pit.
At the crime scene, Zhou Baoguo continued to introduce the findings and some basic judgments of the Dongzhou City Criminal Investigation Detachment. (End of this chapter)
