"Do you think we have reached a dead end in our thinking?" Wang Xu suddenly said, also looking at the map.
"Blind spot?" Bai Song's spirits perked up, and his brain's computing speed instantly soared.
In the last case of Li's murder, when Bai Song put forward his own guess at the end, the possible evidence he thought of later was actually not something he had thought of long ago. If he had thought of it, he would have said it long ago.
Sometimes, when concentrating on thinking about a problem, because of excessive focus, he will enter a state of empty brain and wholehearted attention. In this state, Bai Song's analytical ability can instantly reach full marks, and all known clues and details can instantly appear in front of him.
"Yes, a blind spot," Wang Xu said doubtfully, "This case is quite strange. I always feel that there is something wrong, and I am not the only one who feels this way. Recently, all of Sun's friends, his debtors and creditors, including his wife and daughter, and his relatives and friends, have done DNA comparisons, and none of them match. This is ridiculous."
"If that's the case, the two people at the scene are not these people," Bai Song said, "If it's a blind spot, Brother Xu, I want to ask, do we really know the heights of these two suspects?"
"It's not a big problem. What the neighbor said is relatively accurate. Moreover, the footprints left in the bungalow match the height, weight and body shape." Wang Xu said.
"So, first, did we choose the wrong time period when we watched the video? Second, did we only target the two people who were traveling together? If the two people went their separate ways, would we not have noticed them?" Bai Song thought of two blind spots in thinking.
"That makes sense." Wang Xu said, "Then we have nothing to do, let's just watch the video again."
"Why haven't you retrieved the video here?" Bai Song pointed to an area on the map.
"We went on a business trip together some time ago, and I just started looking into this case yesterday..." Wang Xu said, and saw the area Bai Song pointed to: "Chaoyang Mansion?"
Since the current clues are that the two suspects went to that bungalow, then the surrounding areas of this area may be escape routes.
It is undeniable that due to the detonation of the aerial bomb, some of the original evidence in this PF area was inadvertently destroyed by the special police and exploration personnel who were searching for the bomb. The change of the scene is so helpless.
Opposite this bungalow, that is, to the north, is a road. Across the road is the Daguangli community. To the east is a military camp, which is actually a military academy, so this must be ruled out 100%. To the south is an open space. There is a camera in the military camp here, but no one was found passing by. To the west is Chaoyang Mansion.
The reason why I didn't consider Chaoyang Mansion before was because this community is a high-end community with a wall and barbed railings on the wall. It is really difficult to climb over the wall directly to get in.
"Okay, I'll adjust the video later and come back to watch it." Wang Xu nodded.
In many film and television works, in order to avoid surveillance, the suspects will wait for a long time in some blind spots of surveillance before leaving. This is a very common anti-reconnaissance method. Therefore, we have retrieved a long period of video footage before, but no clues were found.
"By the way, what's the current situation of those three thieves?" Bai Song asked.
"Are you talking about the three people who stole clothes in October?" Wang Xu asked back.
"Um."
"It's still the same. There's no change in the transcripts. The three people were immediately compared with the DNA we obtained, and there was no match at all. These three people can't be the murderers. On the day Sun died, the three of them had alibis." Wang Xu looked at Bai Song in confusion: "You should know all this, right?"
"Well," Bai Song said, "I always feel that these three people are suspicious. I always feel that they stole the clothes just to lure Sun out, and then find a way to kill Sun..."
"Well, I thought you, the little detective, had some good ideas. Weren't you the first suspect? I think this is the least likely. Sun is dead, and the three of them are the biggest suspects. If any one of them did it, or they asked someone to do it, there would be no way there would be no clues after investigating it until now."
"Brother Xu, don't joke with me." Bai Song knew that he was just a young policeman who had only been working for two months and he still had a lot of experience.
"Okay, stop imagining and go check the video." Wang Xu packed up the hard drive. "You were on duty yesterday. You should sleep and rest today. I can go by myself."
"It's okay. There was no alarm last night. I slept well."
"Okay then, let's go."
Chaoyang Mansion has a relatively complete set of cameras, and there are surveillance cameras on the walls. If someone climbs over the wall, it will definitely be recorded. The video here has actually been retrieved, but after looking at the video from that period, we still didn't find anyone climbing over the wall.
Wang Xu drove and took Bai Song to Chaoyang Mansion Community. He took the procedures and started to retrieve the video footage. Because there were a lot of videos to retrieve, Bai Song decided to take a walk nearby.
Since he had seen the video footage near the wall here before, Bai Song knew very well the blind spots and locations of these cameras. He walked around the community for a long time but found nothing.
There are too many blind spots in surveillance, but it is almost impossible to avoid them completely, because some cameras directly record the entire road, and people can't fly, so they can't avoid them if they want to.
"How is it? What did you gain?" Wang Xu asked as Bai Song strolled back to the property office.
Bai Song shook his head: "Go back and take a look."
"Well, why did you retrieve so many videos?" Wang Xu pointed at the computer screen and asked, "I saw that you retrieved all the videos until the morning of the second day after the murder. That was when the explosion was set off, right? Why retrieve so many?"
"Now that I'm here..." Bai Song wanted to solve the problem once and for all: "By the way, if you have nothing to do later, can you come with me to the bank?"
"No problem," Wang Xu nodded. "Do you want to go to ICBC to collect your salary?"
"No, let's go to the People's Bank of China. I want to check how many cards and how much money this Sun has in his name." Bai Song thought.
"Team Two is currently being adjusted. Aren't we doing duplicate work?" Wang Xu was puzzled.
"No, I don't just want to know all of Sun's cards and the transaction records of the people around him, I also want to know..."
…
"You are awesome..." Wang Xu was speechless. "Do you know how big this project is? Oh my God, I won't go crazy with you. This will take at least two months. You may not have gone to the bank to get evidence. It is normal for you to wait for half a month for a small piece of data. Two policemen have to wait for half a day. Also, you don't have a police ID now, so you can't get it. You have to ask Wei Suo and others for instructions."
