Wang Liang was overwhelmed. How did he get infected with the virus?
Everyone else was also at a loss. What was going on?
The virus was not that powerful, and Wang Liang was able to restart the computer. After the restart, the screen was still black, so he had to reinstall the system.
As a good programmer, how can you not carry a reinstallation USB drive with you...
Not long after, the system was reinstalled. Wang Liang started the anti-virus software and inserted the USB flash drive again. As a result, the anti-virus software wanted to automatically delete the thing, so Wang Liang urgently "stopped" it.
In the current situation, this thing is quite sensitive. We won't play tricks, we'll just do it.
Generally, a better virus is one that can avoid anti-virus software, but this one cannot be avoided. When the anti-virus software sees it, it wants to automatically delete it, which means it is most likely a virus in the virus database, with at most a few modifications.
"I was careless. It's okay. This shouldn't be a DOS virus. I'll change the system." Wang Liang pulled the computer aside, not wanting anyone to see it. If something went wrong again, he would not let anyone see it...
Wang Liang was looking for the problem with the virus, while Bai Song continued to discuss the case with everyone.
If it is an indiscriminate killing, then a criminal psychological profile must be made first.
After all, the deceased was a middle-aged man with a history of heart disease who needed to take medicine regularly. Replacing his medicines required advance investigation and was not a simple matter. Therefore, the deceased's daily condition could still be investigated as in regular cases.
Currently, the person who knows the deceased's movements best is the driver. The driver provided some tracks during this period, which were also checked, but there is nothing suspicious at present.
Indiscriminate murder does not mean killing people randomly on the street, which will definitely get you arrested. Some people will deliberately commit murders to satisfy their own abnormal psychology without any hatred. Some of these people do it to challenge the police, and some do it to show off to a certain circle.
Thinking of this, Bai Song couldn't help but recall the mysterious organization that the taxi driver mentioned today. This...
"If it is really a motiveless murder, then the suspect should be a very conceited person who is very confident in his IQ. This kind of person is likely to have a college degree or above, be young, not very worldly-wise, and read a lot of books. The probability of being a male or a female is the same," Bai Song analyzed.
"Well, it's certain that he is inexperienced. A mature person wouldn't do such a thing. His education level may be higher than his undergraduate degree, but I think he hasn't entered the society yet." Wang Huadong said, "This is sometimes how students think about things."
"I agree with this." Captain Ji said quickly, "After joining the workforce, everyone is no longer like this after being beaten by society. In school, people are very curious and learn things to the point of being stupid. There is no reverence for others."
Society is really different from school. Sometimes, people who have worked for a few years think about problems completely differently from students.
People who have worked for a few years think that students are ignorant, but many students think that some working people have no dreams...
…
"So, the suspect might be a college student?" Captain Zhou took notes.
"I have statistics here." Bai Song said, "Many cases are not public. The last time I talked with Director Li from the Criminal Investigation Bureau, he gave me a table. For those who kill without motive, in addition to those with mental disorders or psychopaths, a considerable number of those who commit high-IQ murders are college students. Here are the data."
After Bai Song finished speaking, he opened his notebook, and one of the pages contained this note.
"This has narrowed the scope." Captain Zhou carefully wrote it down: "Although it's not the exact direction, the sense of direction is much stronger."
"Besides that, this person has certain channels." Wang Liang interrupted at this time: "This virus has been modified. The person who modified it is very professional and specifically targeted this kind of monitoring equipment. Generally speaking, people who write viruses are not ordinary people. It's not that viruses are so troublesome, but many of them are written by one person himself, and they are very capable. However, this virus should be open source, and it also adds a program specifically for monitoring equipment. The level is very high, better than mine. I don't think this person is the murderer, but the murderer has these resources, which is also very powerful."
"I don't understand this stuff." Captain Zhou said, "It looks like it was indeed done by a young man."
"Not only that," Bai Song said, "There are two hypotheses now. The first hypothesis is that the murderer destroyed the surveillance here just to be prepared. He didn't know we were going to catch Huang."
"You mean, someone in our team leaked the anti-pornography information?" Captain Zhou interrupted Bai Song.
"I also participated in this operation. The initial confidentiality was good. I don't think it's such a coincidence." Bai Song said: "I trust Chief Song and others. Excluding this possibility, the second hypothesis is that the murderer doesn't care where the victim dies. The purpose of destroying the surveillance here is to replace his medicine here."
"Well, it's true. No one can control when others take medicine, but as long as the change happens, death is inevitable." Everyone agreed.
If that's the case, this place is most likely where the crime was committed. Of course, it could also be a smokescreen.
Under the circumstances where Bai Song believed that Song Suo and others would not leak the anti-pornography operation, the possibility of a smokescreen was very low. According to some criminal theories, "if it is not necessary, do not increase the entity", the more you do, the more mistakes you will make, and it is likely that this is useful.
"Let's go for the reconnaissance and get all the information about all the young people who came in and out of the area last night." Bai Song said.
"Don't look for me." Wang Liang poked his head out from behind again.
"Okay, I'll report to Captain Qin." Captain Zhou felt that the case was now clear.
Wang Liang was still struggling over there. After a while, he breathed a sigh of relief and handed the USB drive to Team Zhou. "After checking carefully, I feel that the level of the person who modified it is not as high as I thought at first, but this may be a cooperative product. The level... may be not much different from mine."
"Well, Wang Liang, let's retreat first." Bai Song had some ideas and decided to communicate with his own people.
In this case, he inexplicably had a feeling that what the taxi driver said was true.
It's not just this case. In the cases he handled before, such as the case where Yao Xin killed Yao Mou and Yao Lei, and the case where the son of a dried fruit seller killed Scarface, the murderers were all college students.
At the beginning, Wang Ruoyi, and later the case of Professor Tang’s apprentice, etc., were all students...
In the nurse case a few days ago, the murderer was also a college student...
Wait! Many, many more!
Is this... is this normal???
