Case 14: Purification 4
"Officer Wang, there's a major discovery!"
The detachment leader hurriedly walked into Wang Tao's office.
"What discovery?" Wang Tao hurriedly asked.
The detachment leader put a computer on the table, "This is the computer found in Zhang Ou's house, it is very clean inside, and there is only one browser. However, this is an unknown browser that even our technicians have never seen. ”
Wang Tao looked at the browser named "shadow" on the computer desktop and asked, "Is there anything wrong with this browser?" ”
"According to the technicians, this is a one-way browser, which means that the browser uses a special search engine to access certain websites. After the unremitting efforts of the technicians, a deleted access record was finally found in this browser. They restored the record and found that it pointed to a very unfamiliar domain. However, in order to access this website, you need to verify your identity very complicated. There was no way for the technicians to get into this site, so we hired a lot of experts......"
"Tell the point, I want results!" Wang Tao was a little impatient.
"This is a website called 'ShadowWeb', I have a few screenshots of the website here, Officer Wang, you ...... It's best to be mentally prepared. The detachment leader handed his mobile phone to Wang Tao.
Wang Tao only glanced at it, and his eyes widened in horror.
T City, Ningzhen Station.
"Got it." Xu Ang hung up the phone and said to Jiang Tian, "Lin Xiao, the deceased in the Ningzhong playground case, had a conflict with his family before he died, because Lin Xiao was addicted to the Internet after entering high school, and his grades plummeted, Lin Xiao's parents were angry, and they smashed her mobile phone and computer in a fit of anger during the quarrel, and Lin Xiao ran away from home. Through the records of the railway department, we found that Lin Xiao had bought a train ticket to Q City half a month before his death, that is, the city where the underground parking lot occurred. ”
"Ugh." Jiang Tian sighed.
"Hello, Jiang Tian!" A familiar voice came from behind Jiang Tian.
Jiang Tian smiled, turned around, and waved at the man.
"Haha, Fang Jinyu, I'm here again."
Ningzhong playground.
"You mean, every deceased person has been to the city of the previous deceased the day before the death of the previous deceased?" Fang Jinyu asked.
"With the exception of the first deceased, the remaining three deceased were all the same. I don't think there will be such a coincidence, so I have a conjecture. Jiang Tian looked at Fang Jinyu and said.
"There is not one, but four murderers in serial murders." Fang Jinyu frowned.
"I'm afraid, more." Jiang Tian said worriedly, "Now, we don't know if this killing has come to an end. ”
"So, our next step is to thoroughly investigate the people who came to or left Ningzhen a few days before and after Lin Xiao's death." Xu Ang said, "Fang Jinyu, I hope you can assist us in the investigation together, after all, you also helped us a lot in the last case." ”
"Then I should be flattered?" Fang Jinyu smiled bitterly, "It's not good to say if I can't help, let's say okay first, don't blame me if I can't help." ”
"It's fine." Jiang Tian smiled and patted Fang Jinyu's shoulder, "We still have a tacit understanding." ”
"Hey, hey." Fang Jinyu laughed, and then said with a straight face: "Jiang Tian, if I can really help, then when this case is over, can you please stay in Ningzhen for a few more days and do me a favor?" ”
"What's the busy?" Jiang Tian asked.
"That's going to be talked about then." Fang Jinyu's eyes were a little sad.
Jiang Tian thought for a while, looked at Fang Jinyu, and nodded solemnly, "Okay." ”
"Okay, then let's leave the rest of the matter alone, let's focus on this case first." Xu Ang said.
"Hmm." Jiang Tian took a deep breath, "In addition to the need for the Ningzhen police to thoroughly investigate the relevant personnel, we must also investigate the relationship between the four deceased at present, and there must be some connection between them." ”
"However, we have investigated the communication records, Internet records, and Internet chat records of the four deceased before, and even investigated the situation of writing letters and the like, and there is no intersection between these four deceased!" Xu Ang frowned, incredulous, "Not to mention that they have added friends or anything like that, and even any two of them have not commented on the same news, how can they know each other?" How can it be that the latter person kills the previous person? ”
Jiang Tian thought carefully for a long time, and then shook his head helplessly.
"Yes, they don't even know each other, so why talk about agreeing to kill? Could it really be a coincidence that there is only one murderer? But how could it be so coincidental? Jiang Tian muttered.
"I think that the possibility of this kind of coincidence is extremely small, and I still agree with Jiang Tian's previous conjecture that the latter deceased is the murderer of the previous deceased, so there must be a communication channel between them." Fang Jinyu said, "So could it be that we ignored something." For example, some of the more unpopular chat channels, such as some payment software or network disk software, actually have the function of chatting. ”
"I've thought about all of this before." Xu Ang said with some disappointment, "We have carefully checked all the applications and records on the phones and computers of the four deceased, and there is absolutely nothing missing. ”
Fang Jinyu was silent for a while, and then said: "Jiang Tian, judging from the confessions of the family members or colleagues of the deceased that you said before, have you noticed that the four deceased have one thing in common, they all like to play with mobile phones or computers. After all, writing a letter or something like that is not realistic, and Officer Xu has also investigated, but he has found nothing. So I thought, if there was any intersection between these four deceased, it must be on the Internet,"
Seeing what Xu Ang wanted to say, Fang Jinyu motioned for him to wait for him to finish talking first.
"Officer Xu, you said that you had previously investigated all the chat records of the deceased. In that case, only this last possibility remains. ”
"What is it?" Jiang Tian hurriedly asked.
"The chat between them is an independent website based on a separate server, and it can't be accessed at will or can't be accessed normally." Fang Jinyu said slowly.
"What do you mean?" Xu Ang heard in a fog, "What independent server?" What websites can't be accessed at will or can't be accessed normally? ”
"In our usual chats, the information transmitted is on the servers of the chat software companies. Theoretically, if the three of us have a private server, then the three of us can communicate privately with each other, and if we don't open the access port, we won't be known to the outside world, and if the outside world doesn't investigate deeply, we won't find out. ”
Jiang Tian said thoughtfully: "But, just to keep the chat history from being checked, it's a bit of a fuss to build a private server and a website, right?" ”
"What if this website isn't owned by the four of them, but shared?" Fang Jinyu had a shallow smile on the corner of his mouth, "For example, DeepWeb?" ”
Jiang Tian's eyes lit up, and the corners of his mouth showed a clear smile, "Yes, this possibility is the biggest at the moment." ”
"You two ......," Xu Ang grimaced, "Tell me what to say!" What servers? What to share? What Jeep's? ”
"Brother Xu, it's Deep......"
"your Deep, not Deep, make it clear to me! Well explained! ”
"That's right." Fang Jinyu couldn't help but smile and began to explain: "It is difficult for ordinary search engines to find its content, and there are many of them, several orders of magnitude larger than our usual ordinary websites. It contains N times as much information as all of our websites that we can visit on a regular basis! There are two main ways to form it, one is that the website itself has problems when it is established and cannot be retrieved by search engines, and the other is that the website manager deliberately blocks those search engines to avoid being retrieved by them. ”
