Chapter 31 Chapter Thirty

On Saturday, the county bureau was still working overtime. Gao Dong hadn't had a good rest for several weeks, and the group under him were the same. Seeing that the Chinese New Year was only two months away, if this case could not be solved, a new case would come up. A large group of people don't have to celebrate the New Year. Gao Dong was very anxious, but he could only show that he was confident, who made him the leader. He arranged for a few people from the Municipal Bureau to check the monitoring of Hu Haiping's community. In the afternoon, news finally came that they had found the man in overalls that the witnesses said.

Gao Dong took Zhang Yiang to the office specially set up for the evidence department personnel, and carefully watched the surveillance several times. This monitoring probe was installed on a lamppost not far from Hu Haiping's unit building, and it happened to be able to capture the scene at the entrance of the unit building. At around 1:00 p.m. on Sunday, a man in gray work clothes appeared in the camera. He wore a peaked cap with the brim pushed down very low, and a high-necked jacket with the collar turned up inside the work clothes.From the time the man appeared until he left the monitoring area, he kept his head down, and his facial features could not be seen at all.It was also apparent that the man was wearing a pair of gloves.It can be said that almost no skin on the body is exposed to surveillance.

When the man entered the surveillance, he was holding something wrapped in cardboard, which was flat in shape.When the man stood outside the door of the unit building, he stayed for some time. At this time, he turned his back to the surveillance and could not see what he was doing.Gao Dong guessed that he should be ringing the doorbell. After a while, he opened the door. At the same time, he used something in his hand to block the door that would automatically close. He turned back and took a stone from the flower bed next to it, and pressed it against the door.He picked up the things on the ground and entered the unit building. After a few seconds, he came out with empty hands.

Less than a minute later, the man took the same cardboard-wrapped object again, walked into the monitoring room, walked into the unit building again, and came out with empty hands a few seconds later. In this way, it was carried out four times in total. In the last time, in addition to the thing wrapped in a cardboard, the man also carried a tool bag. After he entered the unit building, he kicked away the stones on the ground and closed the door. The next segment of monitoring took more than an hour, that is, at 2:30, the man opened the door of the unit building and left.This time he only carried a tool bag, and the four items that appeared before were all gone, indicating that the four items were all left in the unit building.

Gao Dong lit a cigarette, watched the surveillance a few times, and after a while, let out a sigh of relief, and asked, "This guy has never shown his face, and he can't see his face. Have you checked the elevator surveillance in the unit building?" "I checked, but I didn't find him. It can be seen that he must have taken the stairs, not the elevator." "Sure enough, I understand." Zhang Yiang asked puzzledly, "Boss, what do you understand?" Gao Dong looked at him: "Do you know why the stone slab was split into several pieces and glued together with tile glue?"

Zhang Yiang shook his head blankly: "I can't figure it out." "At first, I couldn't figure it out, but after watching the on-site surveillance, I knew the answer. Most people can't move such a stone slab weighing more than 60 kilograms. If he wants to get the slate to the sixth floor, he has to take the stairs, or Take the elevator. Why didn’t he take the elevator, but took the stairs? Because there are surveillance cameras in the elevator. Although he is wearing a peaked cap and his collar is turned up, after entering the elevator, the surveillance cameras are very close to him, even if he cannot be photographed The complete face, at least some features on the body or clothing can be photographed clearly at close range. He didn't want to take the risk. He chose to take the stairs. Going up was easier said than done. So he knocked the stone slabs into four parts, about 15 catties each, wrapped them in cardboard, and lifted them up to the sixth floor piece by piece. Then he took out the stone slabs and glued them together with tile glue. , the strength will be firm enough after five minutes. At this time, it becomes a whole stone slab again."

Zhang Yiang opened his mouth slightly, looking surprised.The murderer even did so meticulously in the small link of moving the stone slab up, and then came up with a murder plan of killing people with falling objects from a height, which is really terrible. He thought for a moment, and said: "Boss, since the murderer moved the stone slabs to the sixth floor through the stairs, that is to say, he walked up and down the stairs four times, which would take a lot of time. Let's look for the residents in the unit building. Maybe someone just passed by at that time and met him?" Gao Dong shook his head: "It's useless, so what if we meet again, if instead you meet a decorator passing by when you go downstairs, do you remember his appearance? It's been six days, even if it was true at that time Someone walked by, if you ask now, the person must not even remember whether they have met a decoration worker at that time. Besides, no residents came out of the unit building during the monitoring period just now, and this kind of elevator room, everyone generally They all take the elevator and rarely take the stairs.”

Zhang Yiang nodded helplessly, Gao Dong was right, the human eye is not a camera, you will meet all kinds of strangers every day in your life, no one will remember who they met on the street in the morning, let alone their appearance , unless it is a particularly odd-shaped person. ——Of course, if your natural parents are sorry for you and give you an alien face, anyone who sees you will never forget it, and you still commit crimes, don’t blame the police for being too powerful when you get caught. A young police officer next to him asked: "Boss, it seems that this man rang the doorbell of the apartment building first, and then the door opened. Could it be that his accomplice lived in the building, and the accomplice rang the wired doorbell and opened the door for him?" door?"

Gao Dong sneered and shook his head: "If there are his accomplices living in the building, can you monitor and find out who moved the stone slabs? Why does he have to move the stone slabs four times in a row? He brings a stone slab every few days. Wrapped in cardboard, you'd have no idea there's slate inside." The little policeman who had just joined the Criminal Police Force and was still in the internship period asked naively: "But after he rang the doorbell, someone opened the door for him. How could he open the door for a stranger?" Gao Dong didn't want to talk nonsense with him about this question, he was thinking about how Zhang Yiang would bring all the pig-like stupid people in the team to solve such a big case.

Zhang Yiang had no choice but to explain to his subordinate in embarrassment: "You go to any apartment building with a wired doorbell at the bottom, ring the doorbell above, no matter which household is home, tell the other party that you are from the Internet company, go in and check Network box, please open the door, it will be opened." Gao Dong didn't even glance at the little policeman, called Zhang Yiang aside, and said in a low voice, "You've seen Ye Yuanchao in person, how tall is he, short, fat and thin?" "About 1.7 meters, quite thin." "And the person in the surveillance?"

"I don't see much difference in size, Boss, are you still suspicious of Ye Yuanchao?" Gao Dong pursed his lips: "It's hard for me to answer this question. I told you what Jiang Wei told me that day. The two murders did not involve the victim's property. There was no direct economic relationship between the two victims. It's a vendetta. Ye Yuanchao is the one with the strongest criminal motivation and the strongest criminal ability among all the people I have seen so far. Although there is no evidence pointing to him, but... um... Now the case is entering a bottleneck period. Any possibility cannot be easily ruled out." "However, the two cases have no similarities except that the victim is the top leader of the unit. They don't meet the conditions for joining the case for the time being. Besides, this person's walking style is not like that of Ye Yuanchao. Ye Yuanchao is a bit lame. .” "You said that the two cases are actually unrelated. I have thought about this. The first case was extremely brutal, while the second case appeared to be an accident, and the methods and styles were too different. It may be related to Hu Haiping. The enemy, after seeing Wang Baoguo being killed, hitched a ride to kill Hu Haiping and almost misled us that it was an accident. Even if we found out that it was not an accident, this hitchhiking murder would easily push our investigation breakthrough to the first place. This case is cited and blamed on the murderer who killed Wang Baoguo." "That's right, if that's the case, we merged the two cases and mistook them for the same murderer, so judging from the criminal motive and focusing on Ye Yuanchao, wouldn't it be easy to close the murder case?" Gao Dong nodded: "I understand that if it is the same murderer who has hatred against both Wang Baoguo and Hu Haiping, then Ye Yuanchao has the strongest motive for the crime. If the two cases are unrelated and each has a murderer, then it may be Wang and Hu Haiping. Hu's respective enemies are not related to Ye Yuanchao. But I thought about it, Ye Yuanchao still can't completely rule out the suspicion, you'd better investigate further." Zhang Yiang said: "Boss, I have my own idea. In these two cases, our attention is focused on investigating the relationship between Wang and Hu, and finding out who their enemies are, and which enemies have sufficient criminal motives. Could it be the wrong direction? Maybe the real murderer is not on the list of interpersonal investigations, what if the murderer is a guy who hates society? Or the murderer has been unfairly dealt with by the political and legal system, and has always held a grudge and took revenge on society?" Gao Dong shook his head and denied: "This is impossible. The psychological factor of retaliating against the society is to vent. The bigger the incident, the crueler the criminal methods, the more his dissatisfaction can be vented. Wang Baoguo was killed, the impact is big enough, the means It’s cruel enough. But in Hu Haiping’s case, the murderer’s design was very ingenious, much like an accident. This completely ruled out the possibility of retaliating against society.” Zhang Yiang nodded in agreement with his judgment, and asked again: "Boss, how do we investigate Ye Yuanchao?" "You have already asked, and it is useless to ask directly. If he is really a murderer, he has worked as a scout and criminal policeman, so he must have strong anti-reconnaissance capabilities. Later, I will call and transfer a few experienced veterans from the city. Criminal police, follow him for a period of time. In addition, you have worked very hard to check the surveillance these days. After a few days of hard work, check the other surveillance cameras in the community and the road surveillance outside the community. You must find out the facial features of this person. Today’s monitoring made me understand the reason why the stone slabs were bonded with tile glue, but there are still several doubts in Hu Haiping’s case, including whether the piece of iron sheet in the corner outside the window on the sixth floor is related to the case, and whether it is related to the case. Understood. Well...let's wait for the result from your side first." Gao Dong exhaled, he was very tired.
