Li Rui frowned. He wanted to do it himself and fast-forward the video a third time, but he didn't think it was necessary. The two searches were separated by five seconds. In these five seconds, if someone had entered the room or taken the painting, it would have been shown on the video. Now that there was no discovery, it could only mean that no one had entered the room. But the question was, if no one had entered the room, how did the painting go missing?
Li Ruixin was secretly worried. Seeing that there was no point in staying any longer, he said goodbye to the security guard, turned around, and walked out of the security room. He climbed the stairs back to the guest room.
In the guest house's staircase, there was an open window at the corner of each staircase, which was the dark side. When Li Rui passed by, he casually glanced at the window. When he turned around and climbed up, he suddenly thought of something. He looked back at the window, raised his hand, and slapped his forehead. He cursed, "Damn, why didn't I think of this?!"
His face changed instantly. He quickened his pace and ran up to the second floor. He came out of the stairwell and ran to his room. After entering the room, he went straight to the window. The curtains in front of the window were tightly closed, probably to prevent the sun from shining. He pulled open the curtains with both hands. When he looked, sure enough, the two windows on the left and right were not locked. They were just closed.
It turned out that when he saw the open window on the dark side of the stairwell, he suddenly thought that the painting must have been stolen. Since the thief didn't enter from the front door, he must have entered from the back door. For the guest house's rooms, the back door was the window, so he rushed back to check. Now that he saw that the window was not locked, he was even more sure that the thief had jumped in from the window.
He moved closer to the window sill and opened his eyes to look up. He wanted to see if there were any footprints, but he found that there were no footprints. However, there were dust particles that could be seen with the naked eye, and the dust particles didn't occupy a large area.
"I understand now. The thief has a wealth of anti-reconnaissance experience. When he jumped out of the window, he deliberately used something to wipe the footprints left on the windowsill. However, he only cleaned the footprints and did not remove the dust and sand from the soles of his shoes."
Li Rui was very excited when he thought of this. He raised his hand and wanted to open the window to see if there were similar marks on the windowsill outside. However, when his hand was about to touch the window knob, he suddenly realized that he couldn't do that. If his hand touched the window knob, it would destroy the fingerprints that the thief might have left behind. If he couldn't solve the case himself, he would have to call the police later, and the police would need these clues to solve the case.
He stuck his head out of the window and looked out. There was no balcony, so the outside was only the second floor. But when he looked down, he discovered a new continent. It turned out that one meter below him was the huge semi-open square porch of the guest house.
"Ah, I was wondering how the thief climbed to the windowsill on the second floor. It turned out that he used this porch. The porch has a roof. He stepped on it and moved closer to my window. The height of one meter from the windowsill was like nothing to him. Naturally, he easily jumped into the room through the window. The roof of the porch had accumulated dust and rain all year round, so there was a thin layer of dust and sand. The thief's shoes stepped on it, and part of it was stained, so it was left on the windowsill. "
When Li Rui deduced this, he secretly admired the thief's cunning and cleverness. He thought about it and decided to see how the thief climbed to the porch. Maybe he could use this opportunity to discover the thief's identity and traces. He turned around and left the room. He went downstairs and walked out of the guest house. He stood outside the porch and looked at the semi-open porch. He didn't know if he didn't look, but when he looked, he found something.
The porch was very wide. It was about six to seven meters wide and three meters tall. One side was the door, and the other three sides were empty. There was nothing on the three sides that could be used to climb up. There were two thick pillars on the outside of the porch, but the surface of the pillars was smooth and round. It was impossible for people to climb up. Moreover, there were people coming and going from the guest house's entrance, so it was impossible for people to climb up the pillars openly. The top of the porch spanned across the three rooms on the second floor. The windows of the room in the middle were all within the span of the porch. The windows of the two rooms on the left and right were only half covered. Li Rui's room was the room in the middle.
After looking at the details of the porch, Li Ruixin came to a conclusion. The thief couldn't have climbed to the top of the porch from below. In other words, the thief climbed to the top of the porch from a window on the second floor.
Li Rui looked up at the details of the environment above the porch. Needless to say, one meter above the top of the porch was the window of the room on the second floor. It was the closest to the top of the porch, so it was the most likely entrance for the thief. 1.5 meters above the window of the room on the third floor was the window of the room on the third floor. There were no anti-theft bars installed outside the window, and there was no air conditioning. The wall was covered with mosaic tiles, which were as smooth as a mirror. It was easy for the thief to jump down, but it was impossible for him to climb back. However, the thief could choose to jump from the top of the porch to the ground to escape. Therefore, the window of the room on the third floor was also a possible entrance for the thief.
Li Rui decided to start with the three rooms on the second floor that faced the porch. After all, the probability of the thief jumping to the top of the porch from a window on the second floor was higher. He turned to look at the room on the left side of the porch. He clearly remembered that the room on the left side of his room was occupied by the cadres of Qingyang City's Education Bureau who came with him. Not to mention that they didn't know the existence and value of the painting, even if they knew, they would never have thought of stealing it.
Li Rui narrowed his eyes and turned to look at the room on the right. The window of the room was closed, and the curtains were hung up. It was dark inside, and there was no light. This was reasonable. If the thief really jumped out from that room, he would have escaped after he got the painting. Why would he stay and be caught? Therefore, there was no need to knock on the door of that room to ask.
One more thing could be inferred. After the thief got the painting, he didn't return to the room. Even if he returned to the room, he didn't escape from the front door of the room. This was because in the surveillance video, there was no one who carried the painting in or out of the corridor. That was to say, after the thief got the painting, he jumped from the top of the porch to the ground and easily left the scene.
After analyzing this, Li Rui decided to start investigating the previous tenant of the room on the right. That person was likely to be the thief. However, he was a little hesitant. Should he go to the front desk to ask for the information of that tenant, or go to the security room and ask the security guard to check the surveillance video of that tenant? After thinking for a while, he felt that the front desk lady might not tell him. Instead, she would be suspicious of him. It was better to go to the security guard. At least he was an acquaintance, and it would be easier to find him. After thinking about this, he returned to the building and ran to the security room.
"Hey, why are you back again?"
There was only the security guard in the security room. It seemed that what he said before was right. He was the only one on duty tonight.
Li Rui smiled and said softly, "Aiya, brother, I need your help again. Help me check the surveillance video of the lobby on the first floor. It's from the same time period. My colleague told me that a person with a long paper scroll picked up my key. I want to confirm if he's staying in this building. "
Li Rui had already thought that if the thief had entered the room on the right of his room, then he must have checked out of the room. If he dared to escape without checking out of the room, he would be easily suspected by the hostel and the police. Therefore, after he stole the painting, he must have checked out of the room on the first floor. Therefore, he needed the security guard's cooperation to check out the surveillance video of the lobby on the first floor and look for a man with a painting scroll.
The security guard said awkwardly, "Aiya, I've already checked the surveillance video for you twice. Why are you still not satisfied? Do you want me to be scolded by the leader?"
Li Rui smiled and said, "Good brother, please do me a favor. I'm begging you. If you have time, I'll treat you to a meal."
The security guard was only pretending to be difficult. Seeing that he insisted, he agreed and said, "Okay, this is the last time. I really can't do it again."
He went back to his desk and moved the mouse to find the surveillance video of the lobby on the first floor. He selected two videos from 6 pm to 7: 30 pm and fast-forwarded them.
Li Rui was quickly disappointed again. From the two videos, he did not see anyone with a painting scroll in the lobby or at the entrance. He was puzzled. Could it be that he had inferred wrongly? The thief left immediately after he got the painting and did not check out of the room? Thinking of this, he could not help but hesitate. He suspected that he had inferred wrongly from the beginning.
"Ah … I missed it, I missed it!"
Li Rui suddenly thought of something and cried out involuntarily, giving the security guard a fright.
Li Rui thought that after the thief got the painting scroll, why would he appear with it everywhere? Was he afraid that people would not suspect him? His most instinctive thought would be to hide the painting and check out of the room. It was easy to hide the painting. When people were not paying attention, he could put the painting in the bushes or under the wall. In the dark, how would people see it? If the thief came in a car, it would be even easier. After he stole the painting, he would jump from the top of the porch to the ground, put the painting in the car, and check out of the room in the lobby. Who would know what he was doing before that?
Realizing this, Li Rui was very excited. He asked the security guard, "There are surveillance cameras outside the building, right? Facing the porch left and right? "
The security guard said bitterly, "Big brother, you want to see the surveillance video outside the building again? Are you done yet? "
Li Rui took out his wallet and took out two hundred yuan. He handed it over and said, "Big brother, help me. This is the last time. I'm begging you."
