Several people nodded. Without any idea, they could only do this first. Shao Dong had just thought about a possibility, but this possibility still needs to be thought about again after verifying the window.

Several people drove to Xingmei Community again. Because of a murder, the entire Xingmei Community was shrouded in a tense atmosphere. The security guards also began to investigate strictly and carefully inspect each car, but this did not include police cars.

After a few people came down, they headed straight to the back of the eleventh floor where Wenwen was. Building 11 happened to be the last building in the community. Behind the community is a wall. Before, the wall was planted with a layer of holly in order to beautify the environment. Now in the cold winter, only holly is still green.

Because 1105 and 1106 are surveillance blind spots, after Shaodong got off the bus, he first instructed Ma Si to take out the ruler he had prepared before, carefully measure the position of the blind spot, and see if he could infer anything from it.

After on-site investigation in Shaodong, it was found that there were two surveillance cameras under the eleventh floor, one on the left and right. In fact, when this surveillance was designed, the blind spot did not exist. However, over time, the surveillance camera was severely sagging. At that time, people did not pay much attention, and the surveillance blind spots appeared.

"You see, it's actually not only one that sags, but the others also have changes in their positions, but they are not as obvious as these two.

Let's look for it separately. Go to the security room alone to retrieve all the surveillance. We check it carefully. In addition to this surveillance blind spot, are there any other surveillance blind spots?

Of course, the key point is to look at the high wall behind, and see where you can climb over the wall."

Shaodong had asked Ma Si to investigate all the surveillance of the community that day, and found that except for Zhu Cheng and Wang Bo, no outsiders entered the community.

If it wasn't for an internal crime, then you would have to climb over the wall.

Shaodong asked several people to investigate the blind spots, and walked around the wall alone without missing any details.

After checking all the cameras, I roughly estimated that it is basically impossible to move to the 1105 position except facing the wall in Building 11.

Shaodong also made a special experiment to let Ma Si watch in surveillance and use various ways to avoid cameras. As a veteran, Shaodong has been a policeman in recent years. His physical fitness is definitely outstanding, but he can still be detected.

Finally, Shao Dong inferred that it is absolutely impossible to move from other walls, so there is only one possibility left, which is the wall behind 11 buildings!

After Shao Dong made the final judgment, Zhang Hao kept sighing, scratching his head and said, "But we have watched the surveillance camera many times and found nothing. We thought of it at the beginning. If we want to calmly come to the 1105 window, the biggest possibility is to climb over the wall.

Anyway, Ma Si and I were confused, so we just calculated in seconds, and there was basically no movement."

Shaodong also knows this situation, so the difficulty of this case is that nothing can be found at all, just as everything appears out of thin air, making people confused and unable to find the entry point. Since the establishment of the fifth group, Shaodong has taken three or four such cases.

In fact, Shaodong is already used to it, but this time it involves Wang Bo

.

After Shaodong walked it once, he found that holly was enough to hide his figure. Shaodong inferred that it was because holly could hide some of the figures that Shaodong and others had not seen anything until now.

This holly planted is really interesting. After Shaodong squatted down by himself, he asked Ma Si to check whether he could see it. Ma Si couldn't see anything he said. Shaodong nodded and understood that this was the path the murderer must go in.

Suddenly, my feet twisted and almost fell to the ground. I looked down and saw that there was a small hole under my feet. If I didn’t pay attention, I would easily sprain my ankle.

Shao Dong looked at the wall that was more than one person high and said with a melancholy expression: "Actually, even if we use Wang Bo to do this, it is not true at all. This condition alone cannot be done unless he can be invisible."

Yu Ping nodded, touched the stubble on his chin and said, "Think about the parking position of Wang Bo on the surveillance monitor at that time, it was just in front of the left side of Building 11. If he wanted to move to the back and come to the window, he would have been photographed at the corners of the corners."

Yu Ping originally said something unexpectedly, but Shao Dong was stunned when he heard it. Turned his head and flashed in his eyes. He grabbed Yu Ping's arm and said, "What did you say?"

Yu Ping was a little stunned by Shao Dong's expression. He didn't know what Shao Dong was going crazy, but he still answered Shao Dong's question: "I said... it's impossible for Wang Bo to come here..."

"Next sentence!"

"Because, you will always take pictures of the corners..."

"By the way, that's it!" Shao Dong said with excitement, which made Zhang Hao and Yu Ping look confused.

"Come with me, call Wuwei, and ask if there is any investigation. There is no need to have a lot of accurate time for the death of the body. It's enough to prepare for half an hour. Come with me!" As he said, he walked forward.

Zhang Hao and Yu Ping looked at each other and saw a little excitement from each other's eyes. Shao Dong looked like he had made a major discovery.

When he came to the security room, Ma Si was still looking at the computer meticulously. He actually had no idea, but he just wanted to do his best to find evidence that Wang Bo was not the suspect.

Yu Ping quickly called Wuwei, and Wuwei took over a murder case during this period, so he naturally put his heart on it.

"I can still guarantee it if it is accurate to half an hour, just between 11 and 130 pm."

Everyone knows Wuwei's personality, and basically what can be said, are sure and error-free.

"Okay, as Wu Wei said, we will call out both surveillance monitors in Building 11 during that period. Remember, I am not asking you to see if someone passes by, but if there are any shadows or corners of your clothes. As long as you see this, tell me immediately!"

After Shao Dong's explanation, several people immediately understood what Shao Dong meant. At that time, the sun was hanging high, and if the murderer was accidentally photographed, he would be photographed with shadows or corners of his clothes.

After Shaodong finished speaking, several people began to investigate enthusiastically. They almost refused to let go of any second. As long as there was a turbulence, several people would pause and carefully analyze what it was. Unfortunately, two hours passed, and a few people found nothing valuable except seeing a few dead leaves falling.

In the end, Zhang Hao was so tired that he was weak and covered his eyes and wanted to slap the table: "This murderer is

Not an invisible person, this is too amazing, no shadow is willing to leave us!"

Yu Ping was helpless, took out the cigarette box and put it down. He thought to himself that it was not the time to smoke, and even he began to sigh: "To be honest, I have been a police officer for fifteen years, and I have never encountered so many cases that I can't deal with. Is it because we are not lucky?"

Shao Dong has been sitting in a computer chair, holding his hands tightly together, without saying anything or even blinking.

In fact, the wall is a breakthrough point. Other policemen also thought of it and sent someone to search within the holly. As long as they approach the wall, they searched it, and they didn't even let it go, so basically there was no breakthrough point.

If it were in the past, Shaodong might have thought that it might be that they did not search carefully enough or that they did not search carefully enough, but this time, Shaodong personally participated in the search and almost walked outside the wall, but still found nothing. This made Shaodong start to reflect on what was wrong.

"The murderer cannot have super powers. It's not that we are not careful enough, nor that we don't have enough eyesight. The mistake is not here." Shao Dong said word by word as he stared at the surveillance video.

After hearing what Shao Dong said, several people subconsciously asked, "Where is that?"

Shao Dong narrowed his eyes and flashed an inexplicable look: "What's wrong, what's wrong is not that we are not careful enough, but that we are time."

"Time?" Several people looked at Shao Dong in unison with confusion.

Shao Dong nodded: "Yes! It's time. Our thinking is wrong. The subconscious mind tells us that the murderer went in during this period, and then killed the person and quickly solved everything and left. But we are too confused about this period of time. The murderer may have gone in before. Didn't the guard say that? He went to see it in the morning and did not find anything abnormal. We just looked for it according to the time point mentioned by the old man. Then the span will be longer. It started after 11:00 am, and in the afternoon, a few people saw that 1105 had a big mouth. I know this was a little hard work for you, but this is also the only breakthrough point we can find."

Because the time span is too large, staying in the security room is also a problem, so several people took out their USB flash drives to save the video, and returned to the investigation team to check it overnight. At this time, Wang Bo had been locked up in the temporary detention room.

Shaodong did not go to see him because Shaodong knew that Wang Bo should not want Shaodong to see his embarrassed look. Shaodong just found Xiao Chen, who was guarding the temporary detention room, and called him to give him a few instructions, meaning that he wanted to take care of Wang Bo.

Xiao Chen is naturally not stupid either. Even if Shao Dong doesn't need to explain to him, he will definitely take care of Wang Bo. However, Xiao Chen said helplessly: "Brother Dong, Brother Bo looks really sad. During dinner, he felt that Brother Bo forced him into it. I couldn't bear it anymore. I guess he didn't want you to worry about it."

Shao Dong sighed deeply after hearing this. Indeed... that boy must know that if he knew, he would be even more worried.

At this moment, the phone rang, and the caller was Yao Xue.

"Hey, have you eaten?"
