Chapter 16 Chapter fifteen

Gao Dong was lying in a chair thinking hard, when he knocked on the office door three times, Gao Dong sat up straight and said please come in. Team Chen came in, and Gao Dong said, "How is Cha?" "The people who bought the paint from the two public institutions have already confirmed it. They are all office staff of the unit. They usually do not have any abnormal behavior. The paint was bought back for the propaganda work in the unit, and no doubts were found." Gao Dong seemed to have expected this result, so he didn't say anything. Team Chen continued: "The police from the police station went to Lin Xiao's house and heard from them that there was no one in the Wenfeng apartment where Lin Xiao was renting, and there was no note left. Everything was neat and there was no sign of being tampered with. I told the director of the police station that the leader of the county bureau meant to record the situation first and not file a case for now."

Gao Dong hummed, thought for a while, and said, "Is there surveillance in that Wenfeng community?" "This is one of the relatively high-end communities in the county, there must be one." "Check when he came home last time and when he left the community last time." "Okay, I'll implement it right away." After Team Chen left, Gao Dong lay down on his back again, thinking about Li Aiguo's case. After playing cards in the middle of the night, he drove home alone, turned from Haiyan South Road into Fengqi Road, and drove a distance of three to four hundred meters. What kind of situation made him stop halfway?And who will let him open the car door and let the murderer get in the car?

This is still the key point to solve the case. And most importantly, how did the murderer come to stay on Fengqi Road? During the monitoring, it is easy to check any pedestrians. You only need to see if they leave the next monitoring in a short time to judge whether the person is stranded on the road. Only come by car. The murderer must have come by car, and he must have been sitting in the back parking space, so that the surveillance camera would not be able to capture it. But the common sense of criminal psychology infers that the murderer is alone and has no accomplices, so the driver should have nothing to do with the murderer.However, all the vehicles passing Fengqi Road that night have been checked, and the drivers all said that no one got off the vehicle halfway.what on earth is this kind of happenings?

Gao Dong still couldn't figure out where the point of the contradiction lies. Could it be that the murderer has an accomplice this time?The driver of the car is his accomplice? Or maybe it's because the inspection work of hundreds of vehicles is heavy, so it's impossible to make detailed records for each driver that night, and it is easy to make mistakes. Did the police neglect and omit it during the investigation? But now the golden investigation period has been missed, and ten days have passed since the crime happened. Even if the vehicle carrying the murderer is found now, as long as the murderer is not a strange-looking person, the driver must not remember the murderer's appearance clearly.

At the beginning of the incident, Gao Dong set out to work in five directions. Now the first direction, the monitoring of Zhafengqi Road, is doomed to fail. The second direction, some time before the investigation, Li Aiguo was followed by someone while driving.This part of the work is numerous and difficult. Presumably the murderer was extremely careful when following him to avoid being discovered by Li Aiguo himself.Now it is even more difficult for them to find out who followed Li Aiguo from the surveillance.But one thing is certain, the murderer must have followed Li Aiguo, as long as he carefully checks and monitors, there will be results in this regard sooner or later.All we can do now is wait for the results.

The third direction is to check the physical evidence left by the murderer.The only valuable physical evidence is the writing, but the clue of the paint has been broken, and it is difficult to make a breakthrough in this regard. In the fourth direction, Li Aiguo's relatives and friends took notes and checked social relations.This piece of work is still in progress, but so far, there is no valuable information. The fifth direction is to visit the vicinity of the crime and ask the people.This piece of work is nearing completion, so far there are no witnesses or insiders. It seems that the most reliable now is the second direction, who followed Li Aiguo.This is the most rewarding job available today.

Thinking of this, Gao Dong called Zhang Yiang, and said, "How about calling the surveillance in the whole county to find out who is following Li Aiguo?" "It's...not yet." Gao Dong hummed, and said: "There is no doubt that the murderer has followed Li Aiguo and knows Li Aiguo's whereabouts like the back of his hand. Logically, this work should have results soon, and there are no valuable clues yet. Where? Is it a heavy workload?" Zhang Yiang bowed his head and said: "It's not a matter of workload. The county bureau and our own people have been busy with this job these days. Every surveillance in the county, as long as there is a scene of Li Aiguo's car, we have watched it many times. There is really no Found someone suspicious."

Gao Dong snorted coldly: "Can you see suspicious people just by looking at them?" Zhang Yiang was a little terrified, and said: "I...we are thinking, since the murderer can get into Li Aiguo's car, he should be an acquaintance of Li Aiguo, we can investigate from this angle. If he is an acquaintance, then... then I think, the murderer said Maybe there is no need to follow Li Aiguo." Gao Dong pursed his lips, looked at him with a frown, and said, "Have you ruled out the people who played cards with Li Aiguo that night?" "Well, after they finished playing cards, they separated. From the surveillance at another intersection, they all took pictures of their cars passing by. They all have alibi."

"Since these people are not the murderers, even if the murderer is an acquaintance of Li Aiguo, how could he know that Li Aiguo came home so late that night? He must have been followed. This follow-up is not such a coincidence. I just followed up that day and found out that there was a chance that day. The murderer must have followed for many days before he found this opportunity that night." "What if, if it was one of those few people that night, who appeared to be close to Li Aiguo, played cards together, but actually hated Li Aiguo, and hired a murderer?" Gao Dong said coldly: "What do hired murderers do with guns? Hired murderers see cash in the drawer besides bullets. Why don't they take it? There are such killers who don't need money?"

Zhang Yiang was immediately trained by him to dare not speak. Gao Dong's tone softened, and he said, "When investigating a case, you need to see the essence of the problem. You have to put yourself in the shoes of the murderer and simulate the scene of the crime. You can't solve the case from the standpoint of a third party. Especially you have to know, The murderer's anti-reconnaissance ability is extremely strong this time, and I'll tell you the truth, I've never encountered a murderer of this level." Zhang Yiang lowered his head and said, "I understand, boss."

Gao Dong said: "You check who has followed Li Aiguo. You can't judge which car is suspicious just by feeling. You need to analyze the data. The time when Li Aiguo's car passed the camera, all the cars that passed by within five minutes after that, including some electric cars , mopeds, and vehicles without license plates, as long as the speed can keep up with the tracking, write them all down and list them in a table. Make statistics on the situation when passing each intersection every day, and take out a report to see which ones The car appeared the most. Send me the report within three days." Suddenly, Zhang Yiang realized, according to Gao Dong's method, he counted all the cars after Li Aiguo's car passed by each time, listed which cars appeared the most times, and those cars with the most times, one of them must be the murderer.This method is much more reliable than their experience and feeling to judge which car is tracking. Now is the digital age, and the spirit of data analysis must also be used to solve crimes. Perhaps Xu Ce didn't expect that Gao Dong's idea of ​​solving the case, at least so far, is in the right direction, but there may still be flaws in the details.If Gao Dong continued to investigate along this road, how long could Xu Ce remain hidden?
