deep sin

Chapter 414 Password
In the afternoon, when news came back, Li Fang did what he said. After leaving the Public Security Bureau, he went home alone, and did not continue to pester Ji Cheng. Ji Cheng also asked for leave to go home, and did not go back to Z University to continue. Work, which made An Changpu and Qin Ruonan somewhat relieved.

There is still no clue about Shen Danian's true identity, and the investigation of the people who Jiang Yan had acquaintances with before disappearing also has a feeling that it is gradually reaching a deadlock. I don't know if it was inspired by the postcard and other clues, An Changpu and Qin Ruonan started No matter whether Shen Danian's death is related to Jiang Yan's or not, based on Jiang Yan's murder, could this case be more than just the "simple and crude" kidnapping and murder as originally thought?

Qin Ruonan connected her mobile phone to the computer, printed out a few copies of the photo with words on the door, and looked at it for a long time. At first, she wondered if the relatively short number "32534332" could be a phone number. Number, after trying to inquire, it is found that this is not the case, and the other group of long numbers "4214502752341985" seems to be even more irregular, saying that it is a certificate number, not only does the number not conform to the arrangement of the certificate number, but also the number of digits not enough.

"Before Jiang Yan was killed, she received a postcard with 'future date' printed on it. These two sets of numbers only appeared on the gate after Shen Danian moved into the small house he bought. Does it feel like a preview?" Qin Ruonan raised his head from the numbers and said to An Changpu.

An Changpu was also thinking about the same thing. He read the key points of the conversation he wrote down when Hu Yingying came to deliver things, and what he thought of was similar to Qin Ruonan, except that besides the postcard, he also thought of another thing. .

"Do you still remember what Hu Yingying said, that Jiang Yan received a courier mail without the sender's information, and inside was an envelope. After the envelope was opened, a small card was found. The card smelled bad, and it was smeared What about the excrement?" An Changpu asked.

Qin Ruonan nodded, expressing that he still had an impression of this matter.

"I originally thought that it was an act similar to a prank, but someone was dissatisfied with Jiang Yan and disgusted her in that way to achieve the purpose of venting, but now looking back, I think we are Isn’t it a little too simple?” An Changpu leaned over, picked up the postcard Qin Ruonan put on the table, and pointed to the date on it, “The reason why we are sensitive to this date is because it is more sensitive than the postmark. The time on the Internet is much later, and coincides with the actual murder time of Jiang Yan speculated by forensic doctor Zhao. The stinky card smeared with excrement is just a random word from Hu Yingying, so we treat it as a completely independent matter. , but if you look at the cause of death when Jiang Yan was killed, don’t you feel that something has come to mind?”

"Didn't Forensic Zhao say that she was drowned and inhaled a large amount of sewage mixed with feces..." Qin Ruonan hadn't reacted for a while, and when she was halfway through her words, she had already realized the meaning of it Relevant, "My God, speaking of it, that card is actually very likely to be sent by the same person! Combined with this postcard, isn't it exactly the date and method of Jiang Yan's death!"

"My current guess is the same, so if our guess is valid, the complexity of this case is much deeper than we originally expected!" An Changpu's face looked a little dignified, his His eyes shifted to the sticker with the word "tweet" on the desktop, and he looked at Qin Ruonan again, as if he wanted to say something, but hesitated a little.

"I know, we'll go back and look for those three notes after get off work today." Qin Ruonan understood what he hadn't said, and immediately stated his position again in order to reassure him.

"Having said that, if our guess about the two cards Jiang Yan received is true, then the murderer's intention is obvious. He just wants to play 'guessing' with the victim to see if the victim can meet the deadline. See through his intentions, so..." An Changpu took a copy of the number on the door of Shen Danian's house, and while quickly speculating about the possibility in his mind, he said, "If these two cases are really related to Zhao Forensic The judgments are the same and they are related, so what Shen Danian got is not just riddles, but two sets of codes!"

"Guessing riddles is not my strong point, let alone this kind of thing." Qin Ruonan was a little worried.

"You have to try it, especially if you have received it before. I think a person has his own style, and he might be able to master everything." An Changpu said confidently, but his expression was full of worry. Anyone can see it.

After Tian Yang and Mo Dou came back, An Changpu also communicated with him and Qin Ruonan about their latest discoveries and conjectures. Both of them felt that their ideas made sense, and they became interested in those sets of "passwords". , four people gathered together to study.

"Could it be Morse code?" Mo Dou put forward his own point of view, "Aren't many people who play with codes also play with Morse code?"

"Probably not. Morse code uses a combination of dots and dashes to represent different numbers and letters. It is impossible to write a bunch of numbers directly." Tian Yang shook his head immediately, denying Mo Dou's guess, although he also I am not a fan of cryptography, but I still have a rough understanding of Morse code, something that is often heard.

"What else could it be?" Mo Dou scratched his head.

"What's the use of blind guessing? It's better to check how many common types of passwords there are, especially those that appear in digital form." Tian Yang started to look up the types of passwords on the computer while talking, and turned his head to look. Finding that An Changpu was staring at the computer screen intently, looking down from time to time to see if the number on the piece of paper in his hand matched a certain type of password, he couldn't help sighing softly, and whispered to Mo Dou, "If Nan might be involved this time, Changpu must be under a lot of pressure right now."

"Three cobblers are better than Zhuge Liang. How about the four of us? I don't believe that the combined IQs of the four of us can't solve this problem!" Mo Dou was gearing up, "It's really not possible, please help and invite Dr. Lu here alone. His head is at least as good as any two of the four of us, I don't believe it, but it can also make people break ground on Tai Sui's head!"

Indeed, although Qin Ruonan is An Changpu's girlfriend, she is also a member of the serious crime team. We usually get along very well both at work and outside of work. Coupled with the special nature of this profession, Now thinking that there might be someone secretly plotting to kill Qin Ruonan, Tian Yang and Mo Dou were also angry at this provocative behavior.

Passwords are familiar to everyone. Whether it is a bank card or some online accounts, passwords are inseparable. However, when the password is not only used for protection, but also becomes a way The number of carriers, types, and possibilities have all increased, especially when the information hidden behind these numbers is presented in which language, is it Chinese characters?English?Pinyin?Or any other form, no one knows, there is no hint, what can be done is to try all the ways that seem possible, and try to see which one can successfully form a smooth message and express a clear meaning.

The four of them tried many ways, tried to turn two strings of numbers back and forth many times, but they still couldn't successfully connect them into a complete sentence or word, whether it was a number and a number corresponding to the attempt, or two or two, Or three, all with the same result, which made them all a little annoyed.

The less progress was made, the more irritable the mood became. When it was time for dinner, Tian Yang went outside to carry four boxes of lunch and came back. The four of them continued to discuss the number while quickly filling their stomachs, and then they all split up to analyze From those two sets of numbers.

At about eight o'clock in the evening, Zhao Forensic made a call to the serious crime team. I haven't left yet, so I guessed right."

Forensic Zhao didn't know about the password, let alone that Qin Ruonan had received similar password slips, so he was just doing routine work that wasn't much different from ordinary work, unlike An Changpu and the others had mixed feelings.

An Changpu quickly asked: "Forensic Zhao, is there anything you can confirm?"

"Yes, the deceased this time is the same as Jiang Yan. He should have not eaten for at least two or three days before he was killed. He was in a very weak state when he was killed. The wrists of his hands are also the same as Jiang Yan. There are signs of being tied up. , but what surprised me was that I originally thought that the reason why this person had no resistance when he was strangled to death was because of anesthesia or other reasons that caused him to have no resistance, but I did not find any in his body. The composition of the anesthetic, that is to say, he should have given up struggling automatically at that time. This is very strange." Forensic doctor Zhao knew that An Changpu and the others were eager to confirm whether the two cases were related, so before the written report was written, they first Inform them on the phone, "Although one of these two people was drowned and the other was strangled to death, the murderer's modus operandi and style are completely consistent. From my point of view, I think they are the same person or the same gang. for."

"Then we know, thank you for your hard work, Fayi Zhao!" An Changpu sighed softly, and thanked Fayi Zhao.

In fact, during this afternoon, he was secretly looking forward to it. Forensic Zhao finally came to the conclusion that the two cases were not related. In this way, if they were treated as independent cases, the so-called "password" guessing would be impossible. It may not be established, and the chance of Qin Ruonan being involved will be correspondingly reduced.

It's a pity that the two cases are still related, and their judgment on the "password" is no longer aimless.
