Firefighters found gasoline residues at the crime scene, indicating that the suspect was likely to have used gasoline as a combustion aid to perform arson. Then if the other party enters the park, it is very likely that he took some transportation. Otherwise, if the other party enters with gasoline, it is very likely that the security personnel will be at the attention of the security personnel. After all, the logistics park is a key fire protection unit. If the other party comes in with gasoline, if he comes in swagger, he will definitely be investigated, so the other party is likely to drive in.
"If you investigate like this, it may indeed be faster. I will arrange an investigation immediately." Zhang Hui said.
This logistics park has just been built not long, less than 5 years, so the infrastructure is relatively good. All incoming vehicles will be recorded at the entrance and exit locations. As long as Zhang Hui contacts the logistics park and exports all license plate numbers that enter and exit the day, he can hand them over to all the companies in the park for confirmation. In this way, these vehicles that do not receive the company can be quickly locked. Since the suspect has set fire, it is very likely that he will come to the park to do this, and the possibility of delivering goods is not particularly high. Moreover, the time for the other party to enter and leave should be relatively short. Then, by investigating the situation where the parking time of entering and leaving vehicles is relatively short, it is possible to narrow the scope of the investigation. If compared with these vehicles without the receiving company, it is possible to further lock in the suspect's means of transportation.
After listening to Zhang Hui's arrangements and deployments, Lu Chuan did not make any other arrangements. The other party has considered it more meticulously. If you investigate one by one from these entrances and exits, you should find some clues. Of course, what is the specific situation? You have to wait for the results after the investigation. Whether the suspect entered the park on the day of the incident and the park on the day of the incident is actually hard to say.
The entire logistics park covers a very large area. Moreover, there are vehicles entering and leaving the entire logistics park from morning to night. Especially at night, because trucks are prohibited from traveling with each other during the day, small trucks enter during the day, and large trucks can only enter and exit the park at night. So the traffic may be even higher at night. The investigation of this work is relatively difficult, the workload is relatively large and requires great care.
After entering the park, Lu Chuan carefully observed the path from the intersection where they were to the crime scene. As he said just now, there were basically no cameras, and some cameras were all at the corners of their respective warehouses. There is basically no surveillance camera coverage network in the entire park, so it is unlikely to find some clues through surveillance at the crime scene. Guangming District Public Security Bureau also conducted relevant investigations. The warehouse at the scene did not monitor the surveillance video. Although there were warehouses around the surrounding area, no valuable clues were found. The surveillance cameras a week ago have been copied, but after a week of investigation, no trace of the suspect was found. The vehicles traveling to and from some warehouses around them have also been investigated. Judging from the materials currently provided by the Guangming District Public Security Bureau, there are no major clues.
The warehouse has set up a cordon. In recent times, during the investigation by Guangming District Public Security Bureau, people have been sending people to block the scene. Although this case was accepted by the Criminal Investigation Detachment, the Guangming District Public Security Bureau still needs to provide relevant resource support. Some basic work is still done by people from Guangming District Public Security Bureau. When Lu Chuan arrived at the scene, the deputy director in charge of criminal investigation of Guangming District Public Security Bureau was also on the scene.
"Lu Zhi! I'm really sorry! We have caused you such a big trouble just now," said Chen Weida, deputy director in charge of criminal investigation of Guangming District Public Security Bureau.
Lu Chuan also knew each other. When he was in the Criminal Investigation Detachment, he had handled cases from the Guangming District Public Security Bureau.
"Director Chen is polite. They are all family. When the files were transferred to the Criminal Investigation Detachment yesterday, they had already done analysis and research. This morning, we happened to hold a case analysis meeting to re-track and investigate some clues that have been discovered. In the future, we need to provide some information from our Guangming District Public Security Bureau. "Lu Chuan said.
"Don't worry, Lu Zhi, we will do our best to cooperate with the work of our Criminal Investigation Detachment. If you need it, please speak up." Chen Weida said.
Chen Weida just received a notice saying that Lu Chuan was coming to the scene. In fact, Chen Weida did not expect that Lu Chuan would come to the scene in person as the captain of the Criminal Investigation Detachment. So when Lu Chuan left the Criminal Investigation Detachment, he also took a bus from the Guangming District Public Security Bureau to the crime scene, just 5 minutes before the other party arrived. Not to mention that Lu Chuan is now at a higher level than him, just say that this case was originally from the Guangming District Public Security Bureau, but the Guangming District was unable to handle it and handed over it to the Criminal Investigation Detachment. So whether it is out of politeness or Lu Chuan's position is higher than him, he should have to come here as a matter of course.
"Okay, Director Chen, I'll go to the scene to inspect it first. You know that I used to be a field survey. See if there are any new discoveries." Lu Chuan said.
"Okay, you're busy. Several of the backbone of our criminal police brigade are here, and there are also criminal police officers who are on-site investigation. At that time, they were doing the on-site investigation. You can arrange it directly if there is any situation." Chen Weida said.
It was not the first day that Chen Weida and Lu Chuan had a deal with each other, and the two of them were not polite. After explaining some relevant situations clearly, Chen Weida kept several backbones of the Criminal Police Brigade of Guangming District Public Security Bureau and the criminal police who were on-site investigation. Among these people, he actually plays the least role here. Although Chen Weida has his own analysis and opinions on this case, now is not a good time to tell Lu Chuan. The other party has just taken over the case. If Chen Weida said too much and gave Lu Chuan some of his own ideas, it is very likely that it will affect the other party's judgment.
"Okay, Director Chen, then I won't be polite to you." Lu Chuan said. After saying that, Lu Chuan had already put on gloves and his foot covers entered the crime scene. The warehouse at the crime scene is about 2,000 square meters, and the area is still relatively large. The area of overburden basically covers the entire warehouse. However, because the discovery was timely and the fire alarm came here quickly, the entire warehouse was not completely burned, but the inside was basically blackened. (This chapter ends)
