This killer was extremely cautious. Of course, we cannot rule out the possibility that this was a gang crime. They got three bodies, and the bodies were bleeding, but they didn't leave any traces. The clues were once again cut off here.
Long Xiangtian looked around and saw that Santang Street was just one street. The crime scene was in the middle of the street. There was no entrance or end of the street, and there was no other intersection leading to this place.
Therefore, the clues at the scene are really clear at a glance, and it is impossible to miss any inconspicuous corners due to carelessness. So if they did not find any abnormalities, it means that the killer really did not leave any traces.
"Let's go back and check the surveillance!" Long Xiangtian patted Yang Zhi on the shoulder. Yang Zhi nodded helplessly, and then ordered the team members to not miss any inch of the crime scene and to take careful photos for archiving.
Although this place will be blocked for three days, we cannot rule out the possibility that someone will sneak in and do something, destroying the scene, so we need to take pictures first.
"By the way, Ajing, take two teams to check the surrounding area to see if there are any missing persons. Investigate the residents of the surrounding streets!" Yang Zhi suddenly remembered this matter and quickly gave the order.
He was also frightened when he came here, so he didn't think of this for a moment. He patted his head, looking annoyed. Fortunately, he remembered it, otherwise he might have missed some important clues.
Long Xiangtian didn't have much hope. Since the killer had already chopped off the head and taken it away, it meant that he didn't want anyone to know the identity of the deceased.
Then the deceased should not be a resident of the surrounding area. Even if it is, it is not a bad thing for the killer to disguise some evidence. The fact that they did not leave any evidence at the scene is enough to show that the killer is smart and powerful.
Long Xiangtian and his team returned to the team and of course brought the bodies back with them. It was impossible for them to leave them in the open air. It was just that the judge in their bureau was away for the past few days, so they had to seal it up temporarily.
As soon as Yang Zhengwei came back, he said that he was tired and went back to the office to rest for a while. He left the rest of the matters to Yang Zhi and others. Yang Zhi naturally nodded. He was very concerned about his physical condition and told him not to worry and to have a good rest!
Long Xiangtian felt a little strange and followed him to see what he was doing, but he closed the door as soon as he entered the office. Long Xiangtian put his ear close to the door but did not hear any phone call from inside, so he had to leave first.
Yang Zhi saw Long Xiangtian walking over and asked, "Where have you been? You're gone as soon as you turned around. Come here and watch the surveillance with us!" He muttered to himself, there are so many surveillance videos, when will we be able to watch them all
Long Xiangtian made up an excuse and said that he was going to the toilet, and then went over to watch the surveillance video with Yang Zhi. Since no abnormalities were found on Yang Zhengwei's side, they put it aside for the time being.
However, there were five of them in total, and they checked the surveillance cameras in front of five stores, but they found nothing. The surveillance cameras could only capture the entrances of their stores, but not the situation on the street. And it just so happened that there were no surveillance cameras installed on that street.
"Ouch!" Yang Zhi punched the table. The loud thump showed how much strength he used, but he seemed not to feel the pain. He was only upset because he couldn't find any clues.
"Perhaps we have overlooked one thing. The surveillance cameras at the doors of all the shops on the entire street should be copied back. Maybe we can see the suspicious people coming in and out!" Long Xiangtian suddenly said.
Yang Zhi also reported the incident and sent someone to go immediately. The team members also knew the importance of the matter and came back quickly. There were more than ninety stores on this street, and each store had surveillance cameras at the door, but only about seventy stores were open yesterday and today.
"The surveillance cameras in some stores are broken, so they are not turned on. But the owner of one store said that it broke just today. It was working fine when he checked in the morning, but it broke when he went there just now!" The young police officer handed the surveillance camera to Yang Zhi while reporting the situation.
When Yang Zhi and Long Xiangtian heard this, they looked at each other and quickly asked which store it was. After the young police officer explained, he played the surveillance footage of that store. Sure enough, there were still footage from last night and even in the morning, but the screen suddenly went black.
The time period of the black screen was exactly the same as the time when they received the alarm. It seemed that the store's surveillance camera should have been able to capture something, so it was destroyed in advance by the killer, Yang Zhi guessed.
But Long Xiangtian thought differently. He suspected that the killer hacked into the surveillance camera and damaged the surveillance equipment after taking the video, just to create an illusion.
In order to verify his guess, Long Xiangtian immediately started operating on the computer. Yang Zhi didn't react at first and only saw Long Xiangtian's fingers flying on the keyboard.
But he did not stop it. Instead, he watched different screens gradually appear due to Long Xiangtian's constant movements of his hands. Only then did he realize that Long Xiangtian was using hacking techniques.
"It is just as I expected!" Long Xiangtian pressed the last enter key and looked at the content displayed on the screen. He said this in a confident tone, as if he had guessed it right, but also with a little regret.
Yang Zhi didn't understand what Long Xiangtian meant, so Long Xiangtian told him his guess and interpreted for him the meaning of the content displayed on the computer screen.
"See the progress bar below? The bright one is what we just saw, and the extra grey hour at the back is the part that was originally there but was blacked out."
Yang Zhi took a closer look and saw the gray progress bar with more than an hour left. He immediately believed Long Xiangtian's words, slammed the table, and said in annoyance: "This killer is really cunning!"
But more than that, he was annoyed with himself for not thinking of this when he first arrived at the scene, giving the killer the opportunity to destroy the evidence.
"Long Xiangtian, since you were able to find out that the video was hacked, can you restore it?" Yang Zhi asked Long Xiangtian anxiously. If they could restore the video, they could get information about the killer.
Long Xiangtian shook his head and said regretfully: "I'm sorry, I'm not capable enough and can't restore it. And as far as I know, this killer was completely destroyed and ordinary hackers can't restore it."
Yang Zhi had just had a little hope, but when he heard Long Xiangtian's words, he felt as if he had fallen from heaven to hell. However, he could not blame Long Xiangtian. If it weren't for Long Xiangtian, he would not have known that there was something wrong with the video.
However, this incident also made him think deeply. The killer did not destroy the surveillance at the beginning, which meant that he had not thought about this at all, or thought that he would not be recorded, but why would he come back and destroy it later
