After the two left, they went to the technical department, and on the way, Wu Rui suddenly remembered his previous guess, thought about letting Lao Zhou go first, and he turned back to Di Bai.

At this time, Di Bai was analyzing the case with Xue Zhengnan, and when the two saw Wu Rui going and returning, Di Bai asked curiously: "Comrade Xiao Wu, do you have anything else?" ”

Wu Rui had already thought about it when he came, and immediately said to Di Bai: "I have something I want to report to you separately, which is about Zhuang Yidong. ”

Wu Rui's words were already obvious, Xue Zhengnan smiled and said, "I'll go out and have a look first, and you can talk." ”

Wu Rui didn't know if Xue Zhengnan's heart was unhappy at this time, but he couldn't care about it so much.

When Xue Zhengnan walked out of the room, Di Bai waved his hand at the chair next to him and motioned for Wu Rui to sit over: "Let's talk about it!" What do you want to report? ”

Wu Rui sat down and said with a serious expression: "I suspect that there is Fu Dayu's inside line in our team. ”

This is a sensitive topic, but Di Bai didn't seem surprised, and said calmly: "Tell me your basis." ”

Wu Rui told Di Bai the doubts in his heart when he was looking for Zhuang Yidong's whereabouts in Kangtai County, if it weren't for the fact that the police had Fu Dayu's insider, they would not have been able to make an emergency response at the first time, and at the same time cover up their whereabouts and destroy the tools of the crime.

There is also the fact that Zhuang Yidong passed through the door of the police station and did not enter, which is very strange.

Di Bai was slightly surprised in his heart, and nodded: "We have long suspected this, but we can't be sure who is Fu Dayu's inside line, whether it is one person or several people."

Before the accident, Comrade Zhuang Yidong was also conducting this investigation at the same time, but he never mentioned that there might be ghosts in Kangtai County.

I wonder if it was because Zhuang Yidong found something, or obtained some evidence, so he was taken to the western suburbs for torture, otherwise they could have just killed him, and there was no need to be so troublesome. ”

Wu Rui saw that Di Bai's expression was calm when he listened to his report, and he guessed in his heart that he should have discovered this a long time ago, and Di Bai's words confirmed his conjecture.

Wu Rui suddenly had an idea: "I still have a guess, with Zhuang Yidong's criminal investigation experience, no matter how fierce the gunfight scene was at that time, no matter how panicked he was when he escaped, he should not lose his judgment on the direction."

Could the reason why he fled to Kangtai County mean something, could it be that one of his findings has something to do with Kangtai County? ”

"There is such a possibility, from what I know about Xiao Zhuang, it is indeed very abnormal for him to do this." Di Bai suddenly perked up when he heard this.

Di Bai is Zhuang Yidong's direct superior, the two have always been one-line contact, with his understanding of Zhuang Yidong, no matter how fierce the scene is, he will not be out of proportion, maybe his escape to Kangtai County does have another deep meaning, is he trying to lead the police's attention to Kangtai County? Di Bai couldn't help but think so.

Wu Rui thought about it and suggested: "I think we can secretly investigate, all the industries of Daewoo Group in Kangtai County may have some gains, by the way, there are also industries of Fu Daewoo's relatives or cronies." ”

Di Bai looked at Wu Rui appreciatively and nodded: "Your analysis is very reasonable, this is a new way of thinking, I will arrange a reliable person to investigate secretly." ”

Then he sighed and said: "There are always these scum who corrupt the country's atmosphere, I don't know how many moths will be dug up this time." ”

Wu Rui didn't say anything, and said: "That's what I want to report, leader, then I'll go first." ”

Di Bai personally sent Wu Rui out of the door, and at the same time told him to be careful when handling the case, and report any clues directly to him.

After Wu Rui left the command room, he rushed straight to the technical department on the third floor, Xue Zhengnan and Lao Zhou were sitting and chatting, and Lao Zhang was still cooperating with the technicians to paint a portrait of the suspect with the computer.

Wu Rui went over to greet the two, and after Xue Zhengnan wanted to speak and stopped chatting a few words, he told the two to rest for a while and left the technical department when they were free.

Wu Rui and Lao Zhou immediately found a map of the urban village area, studying the suspect's possible escape direction, and it didn't take long for the portrait of the suspect Liu to come out, Wu Rui immediately asked the technician to send it to Zhang Panpan, and then asked her to send it to units at all levels.

Let all units cooperate in the investigation, now that information technology is developed, the information of criminal suspects can soon be transmitted to the mobile phones of the police through the network, and then transmitted to the joint defense teams of each community, and soon an invisible legal net will be weaved, as long as the net is large enough, there will always be clues of criminal suspects.

After Wu Rui and Lao Zhou's key analysis, they marked several key areas and conducted key investigations on these areas.

Time passed minute by minute, the identity of the gunman named Wan Changfa and the head of the security section had been confirmed, and the whereabouts of this person were still unknown, Fu Dayu did not show any abnormality except for being anxious and sad.

Wu Rui and Lao Zhou squinted for a while, in order to ensure that they had more energy to devote themselves to the next investigation, the sky has eyes, the sky net is restored and not leaky, after a large-scale investigation of the cooperation of the police and the people, they finally found out that there is a supermarket owner, and he saw the suspect Liu on the night of the crime.

The supermarket was located in the outer ring of Xincun, about two o'clock in the morning, and the suspect Liu went to the supermarket to buy cigarettes, lighters, and a bunch of snacks.

Since there were not many customers that night, the suspect bought a lot of things and did not ask for change, so the shopkeeper was impressed.

After inquiry, the shopkeeper recalled that the man was quite addicted to cigarettes, and after buying cigarettes, he lit and smoked them, and he was holding a motorcycle cap in his hand, and he came and walked on a motorcycle, and the shopkeeper said that he did not see anyone else except him.

Because this supermarket is facing the street, the desk is facing the door, and there is a searchlight under the plaque outside, so you can see the situation outside, so the shopkeeper will be sure that Liu was a certain person at that time and the direction in which he left.

According to the confession of the shopkeeper, Wu Rui immediately asked Zhang Panpan and the information department for support and asked him to investigate Liu's whereabouts during that time period, and Lao Zhou went to the headquarters to report this important clue.

Halfway to the road, Zhang Panpan replied to the message, they were divided into several groups to investigate the section of the road respectively, Liu drove a motorcycle and finally disappeared near the eastern suburbs wetland, there was no sign of escaping from the city on the highway, if nothing else, Liu should be hiding near the wetland at present.

In addition, it was found that he escaped on a motorcycle from the path next to Highway 3, so the cameras on Highway 3 did not find any trace of him, and his traces were not captured until the intersection of the outer ring road of Xincun, and it is estimated that the other two gunmen should have fled in this way.

So next, they will continue to investigate the tracks of motorcycles that appeared at major intersections in all directions, hoping to find the traces of other suspects.

After Wu Rui and others received Zhang Panpan's reply, they quickly adjusted their route and went to the place where Liu disappeared last in the eastern suburbs wetland, and at the same time, Wu Rui asked Zhao Lei, director of the urban village police station, to send someone to hand over the collected sniff source of Liu to the police dog brigade, and then apply for the police dog brigade to take the sniff source to the eastern suburbs wetland to assist in the search.

In order to increase the efficiency of handling cases, Wu Rui asked for help from the joint defense of various units in the eastern suburbs and participated in the search and arrest work.

When the search began in the eastern suburbs, Zhang Panpan replied again to the investigation information of the road section monitoring, and they regretted that they did not find any traces of the other two gunmen.

After hanging up the phone, Wu Rui suddenly thought that maybe the two gunmen were hiding in an area near the urban village that could not be seen by the surveillance, and then waited until dawn to change transportation and take the opportunity to leave.

If this is the case, it would be difficult to catch them without specific identification information, which could explain their disappearance.

Wu Rui told Lao Zhou about his analysis, and Lao Zhou thought about it and said, "That's not right! Based on the blood stains left in the business, it can be seen that one person was seriously injured, in which case they should be sent to the hospital as soon as possible, so it is inferred that they will not choose the method you said. ”

Wu Rui suddenly said meaningfully: "What if the seriously injured person was already dead? ”

Oh, yes! If the seriously injured person is already dead, then it is possible for another person to choose this safest method to escape from the pursuit, thinking of this, Lao Zhou fell silent.

Finally, at about 4 o'clock in the afternoon, the people of the police dog brigade found Liu in a small shack in the wetland according to the source of smell.

It's just that Liu has died at this time, and he has been hit by six knives and the knife is fatal, which shows that the perpetrator has a clear purpose and is ruthless.

There was a motorcycle, the footprints of the deceased and the murderer, cigarette butts and leftover snacks on the scene, and the police found a group of newly left wheel prints and an oil stain on the dirt road not far away, but there were no other valuable clues.

After all, the police were one step too late, and as for further clues and information, they could only wait for the identification of the forensic doctor and the trace identification department to see if they could find valuable clues from them.

Wu Rui looked at the corpse and asked about the approximate time of death, Lao Zhou, who has rich experience in criminal investigation, preliminarily judged that according to the characteristics of the deceased's death, the time of the deceased's death should be 2-3 hours ago, Wu Rui knew it in his heart.

The clues that were finally traced were broken again, Wu Rui and others returned to the team in frustration, according to the preliminary investigation of the scene, Wu Rui felt that it was not easy to catch the killer who killed Liu.

Because this is a premeditated murder, since it is a murder, the killer will not be left, and important clues such as fingerprints can only rely on investigation to capture clues again, which will cost a lot of time and manpower, and on the way back, Wu Rui fell into deep thought again.

After returning to the team, all the personnel involved in the investigation of the case, except for Qiu Ye and Xu Dong who could not be present because of monitoring Fu Dayu, the heads of other departments were basically there.

Di Bai told the progress of the investigation of the current case and the clues that he had mastered, and then let everyone speak freely and express their opinions on the case.
