The scene has not yet been investigated, so the direction of the investigation cannot be determined for a while, but several target suspects have also been locked, and these people are members of organizations with suspected underworld backgrounds entrenched in various districts.

Since they have been whitewashed over the years, they have not found any evidence of their crimes, so the police have no way to take them, but they have not relaxed their supervision.

If there is no direction of investigation, it is necessary to create an investigation direction, and we cannot sit idly by; this is Xue Zhengnan's consistent strategy in handling cases, and he immediately asked the anti-gang group and the anti-terrorism detachment to mobilize all resources to seek clues related to the case from informants or other means.

After the end of the meeting, everyone took action to try to find the clues as soon as possible, and soon a police officer came to report that they had already recorded statements from eyewitnesses.

Eyewitnesses also knew very little, except for the approximate model of the three cars, and no other information such as the face of the assailant, the accent, and the number plate of the car were unknown.

After recording the confession, they signed a confidentiality agreement, and then Xue Zhengnan had someone escort them away.

I believe that since then, they will no longer dare to seek excitement in this kind of place, but then again, if they don't seek excitement here, they will not let the police know about the case for the first time, so as to quickly make action deployment, you must know that the earlier you know about this kind of case, the faster and higher the probability of solving the case.

The investigation was going on intensely, and Zhang Panpan was the first to get useful information, she checked the surveillance along the way according to the time of the crime, and found traces of three cars suspected to have driven out of the crime scene.

Two of the vehicles suspected to have occurred disappeared along the highway westward into Kangtai County, and the other business drove into the direction of the city and disappeared into the blank area of the urban village monitoring between Rang District and Sa District.

These two pieces of information are very important, and Xue Zhengnan, who has rich command experience, immediately contacted the Kangtai County police, as well as the Longgang Branch under the jurisdiction of the business disappeared area, and dispatched police forces to track down along the way, not letting go of any small road.

At the same time, he asked for help from the police stations of the county and township public security bureaus around the city, where the suspects might have absconded, to set up cards at key intersections to intercept and investigate suspicious vehicles, and at the same time asked Zhang Panpan's modern technology information department to send the information of the three criminal vehicles to various units as soon as possible.

On the scene of the crime, the on-site investigation team and comrades from the Ballistics Expert Trace Identification Section drew up a schematic diagram of the crime scene based on the useful information left at the scene, and based on the trajectory simulated by the ballistic traces, it was basically possible to roughly determine that six people were involved in the shootout.

In addition, a total of four bleeding spots were found at the scene, including a relatively large bleeding point, and according to the traces left at the scene, it was preliminarily judged that one person was seriously injured and the other three were slightly injured.

A large number of valuable fingerprints were found from the objects at the scene, and it is also worth mentioning that traces of torture were found at the scene.

Xue Zhengnan gave instructions again according to the known information, sent the fingerprint information to Zhang Panpan, and asked her to screen and compare, so as to lock up the suspect, and the blood sample was brought back to the team for testing.

The police station near the urban village has dispatched a large number of police officers to begin to focus on the investigation of large and small clinics in the urban village area, not letting go of any clues that can lock the criminal suspect, and all the investigation work is being carried out in an orderly manner.

Three hours later, the Kangtai County police found two vehicles that committed the crime, but the suspects had already fled, and the two cars were also burned, and there were no traces of a fight at the scene, leaving no useful clues.

The license plates of the two vehicles have been removed and the engine numbers have been scratched beforehand, and they are waiting for the investigation team to conduct an on-site investigation for further clues.

After Wu Rui turned around the scene, he returned to the command car, at this time only Xue Zhengnan and Dayong were in the car, and Xu Dong and others were still helping to search the scene, looking for valuable clues that might have been missed.

Xue Zhengnan saw Wu Rui walk into the car, and hurriedly asked, "Have you found any valuable clues?" ”

Wu Rui thought for a while and said, "I can basically conclude that a total of seven people have appeared at the scene. ”

"Isn't it six?" Dayong couldn't help but ask, he had been in the car and heard the conclusion reached by the previous identification team based on the traces at the scene.

"At least seven people." Wu Rui said affirmatively: "Because everyone still ignores one person, this person is a sudden intruder, and it is because of his appearance that the scene is out of control, which in turn triggers this shootout." ”

"Tell me about it." Xue Zhengnan listened carefully.

Wu Rui said based on his analysis after carefully observing the scene: "If my analysis is not wrong, the thing is that a member of this criminal gang was imprisoned here for some reason and tortured.

At the time of the crime, someone sneaked in to save the man who had been tortured, and in the process of saving people, he alarmed five guards, and a shootout ensued.

One of them was seriously injured and three were slightly injured, and the rescued and rescued people escaped in a vehicle parked outside the factory in advance, and were later chased by the guards.

Since the commercial vehicle entered the city in the opposite direction, it was speculated that the seriously injured person was likely to be one of the five guards, plus the person who was driving, which means that at most three people were involved in the pursuit.

At least two people drove into the city in business, and according to the time, the suspect did not know that there was a third party at the scene, and the immediate priority of the two people in business was to treat their injuries.

Therefore, we checked the direction of the large and small hospitals and clinics in the city, and if nothing else, they are lurking in a clinic at the moment. ”

Xue Zhengnan listened to Wu Rui's analysis and nodded: "The analysis is reasonable, I have already classified the urban village as a key investigation area, and I have sent someone to investigate, hoping to find the suspect as soon as possible."

The results of Xiao Zhang's fingerprint comparison are also coming out soon, as long as the suspects can be locked, I believe it won't be long before we can arrest them. ”

Wu Rui took out the small black book he was carrying, tore off one of the pages and handed it to Xue Zhengnan and said, "This is some of the personality and trait identification I made for the six people present based on the information left at the scene. ”

Xue Zhengnan took the paper handed over by Wu Rui, read the analysis of the personality characteristics and habits of each of the six people at the scene, looked up at Wu Rui and said: "This analysis result is very useful, it is a strong evidence to distinguish the criminal suspect, I will send this information to the various checkpoints and urban village police stations." ”

Soon, Zhang Panpan found the information of the four suspects according to the fingerprints left at the scene, and then sent the information of the four suspects, they were called Liu Shuo, Yu Bing, Sun Feiyue, and Sun Feipeng.

After receiving the information, Xue Zhengnan asked Zhang Panpan to immediately send the information of the criminal suspect to various public security units, and it was necessary to strictly investigate and strive to find the traces of the criminal suspect as soon as possible.

From receiving the report to locking up the suspect, the police only took less than four hours, including an hour wasted on the road, and the speed of the investigation was not unfast.

Wu Rui checked the suspect's information, and when he saw Liu Shuo, his pupils couldn't help but shrink, because this person looked exactly the same as his alumnus Zhuang Yidong at OUHK.

Wu Rui looked carefully, he could be sure that this Liu Shuo was Zhuang Yidong, because he couldn't be more familiar with him, even if the two hadn't seen each other for nearly five years, he still recognized him at a glance, just like when he met him in the criminal police team the day before yesterday.

What the hell is going on? Wu Rui was puzzled, although he and Zhuang Yidong belonged to the same public university, they were not in the same department, one majored in psychological criminology, and the other majored in public security intelligence.

They met at a debate tournament organized by the school, and because of their similar interests, the two became good friends, often going to the library together to read books and discuss crime movies and crime cases.

Later, one graduated and the other stayed in school, and the two suddenly broke off contact, but they didn't expect to meet again in this case, Wu Rui really couldn't believe that the alumni of the year had become a suspect in the shooting.

Xue Zhengnan looked at Wu Rui's expression was wrong, and asked suspiciously, "What's wrong?" ”

Wu Rui pointed to the photo of Liu Shuo on the computer and said: "His name is not Liu Shuo, his name is Zhuang Yidong, I know him, he used to be my classmate at OUHK." ”

Dayong leaned over, looked at the photo on the display, and said in surprise: "No! How did the public university become a criminal? ”

Wu Rui frowned and said, "I don't know how this happened. ”

"Are you sure? Is he Zhuang Yidong? Xue Zhengnan looked at the photo on the data and asked.

"I'm sure." Wu Rui affirmed.

"Okay, you can contact Xiao Zhang and ask her to check Zhuang Yidong's information again, plus sensitive words, if you know his origin, it will be easier to check." Xue Zhengnan said.

Wu Rui then contacted Zhang Panpan and asked her to find information about Zhuang Yidong, and Wu Rui remembered that he said that his hometown was in Qinhuangdao.

According to the sensitive words provided by Wu Rui, Zhang Panpan locked and found more than 1,000 information about Zhuang Yidong, but there was no information about Zhuang Yidong that Wu Rui said.

People have left their names, geese have left their voices, and a person's trajectory cannot be completely erased, and there must be some reason for this.

Wu Rui's heart suddenly moved, he thought of Zhuang Yidong's major back then, public security intelligence is a new discipline, and it also serves the public security system, and his wish back then was also to join this glorious and sacred team.

Besides, it can erase a person's information so completely, only within the public security can do it, so Wu Rui guessed that he was undercover?

One of the six people was tied up and tortured, and naturally only traitors or opponents in the community gang would enjoy such treatment, Wu Ruisi immediately asked Zhang Panpan to compare Liu Shuo's fingerprints with the fingerprints found from the tortured person, and the results confirmed that the tortured person was indeed Zhuang Yidong.

Wu Rui immediately told Xue Zhengnan his analysis, this case has alarmed the provincial department, the provincial department has sent a team of experts to arrive, and at the same time promised to provide all necessary support, Xue Zhengnan immediately reported Wu Rui's speculation to the provincial department.

The public security system is very strict about the confidentiality of undercover information, and it is necessary to check the list of undercover agents.

This time, due to the seriousness of the case, which may involve the life safety of undercover police officers, the director of the provincial department personally approved the verification of Zhuang Yidong's identity.
