Chapter 1003 The Third Question
Qi Changye shook hands with Jiang Yuan with a smile on his face, and said seriously: "Captain Jiang, we meet again."
"It's not a good thing." Jiang Yuan also shook hands with Qi Changye, and then shook hands with Qi Changye's colleagues who came with him: "I'm sorry to trouble you all."
"I wish I could have more trouble like you." Qi Changye said at this point, and whispered: "I heard that you found a code book?"
"You still have to check it." Jiang Yuan was both humble and disclaimer. He inherited the legacy of LV5 cryptography, but the technology in this area is still more sensitive after all, and those who engage in espionage are even more sensitive, so it's better not to worry them.
Qi Changye naturally had to check it. The code book is not easy to deliver through the public network, and the few people didn't see it before they came, so they found a room and took out the code book to look through it.
The code book that Miao Liyuan brought back was a notebook with some words written in pen, which looked like excerpts of songs. In fact, they all corresponded to some words, especially numbers and English letters.
The handwriting in the notebook looked a bit sloppy, and the notebook was also an ordinary hard-cover notebook, which was a common commodity at that time.
The few people brought by Qi Changye looked at it very seriously. They first flipped through it, then started taking pictures, and soon, they started to communicate by phone.
After a long time, Qi Changye invited Jiang Yuan, Tao Lu and Director You into the room, looked at the three of them, and said: "The leaders are more familiar with confidentiality discipline than I am, so I won't say much. Let me first say the conclusion, it is indeed a code book, but it is excerpted."
"Can the code book be excerpted?" Jiang Yuan knew that Qi Changye said so now, so he still had to use his. Anyway, it was not the first time he cooperated with them to solve the case, so he asked without hesitation.
Qi Changye nodded and said: "The role of this suspect should be a semi-marginal and semi-core position similar to a traffic officer, so he needs to master some codes. From our analysis, his code book is mainly used to log in."
"Posting in the newspaper and communicating with the other party in secret language?" Jiang Yuan asked.
Qi Changye nodded and said, "Yes. The main thing should be to communicate the time and place to obtain intelligence, and some questions about the amount of money..."
"That..." Director You suddenly interrupted the conversation between the two and said, "I will not participate in this case, you guys can talk."
After that, Director You nodded to Jiang Yuan and turned to go out.
Qi Changye naturally did not stop him, but smiled at Jiang Yuan and said, "Captain Jiang, you can't just walk away. We still hope that you can preside over this case."
Jiang Yuan pulled it a little: "It's not appropriate for me to organize it. Moreover, this case obviously involves things like espionage networks..."
"The case will be commanded and solved by you. If you need any information, we will provide it to you." Qi Changye immediately said, "You have been following the case. Now let us go, you are not at ease."
The last sentence really touched Jiang Yuan's heart.
It's not that Qi Changye and his criminal investigation ability is not strong, but this kind of case 20 years ago, ordinary strong criminal investigation ability is also difficult.
"Then let's take a look at the case first. What can I learn from this?" Jiang Yuan simply sat down, took out his mobile phone, and sent a message to Huang Qiangmin.
Qi Changye pretended not to see it, and said: "We can check the information of that year based on the information in the code book to see if it is a spy network that has been uncovered. If not, it depends on the specific situation, but to be honest, if there is no record, then the clues of the code are basically broken."
"You said that the suspect is a traffic officer. He often goes to the newspaper to register GG, right? Can we find the information of these GG customers?" Jiang Yuan asked.
Qi Changye shook his head: "It's basically impossible. It's been too long, but we can try to find it."
"Then we still have to do it from the perspective of homicide." Jiang Yuan now understands a little bit why Qi Changye is holding on to him.
In the final analysis, it is more appropriate to do this case from the perspective of criminal investigation.
Come to think of it, espionage cases are handled by professionals, and the current cases are difficult to solve. How to solve the espionage case 20 years ago? It's a headache to think about it.
"Call Director Liu to come in and sort out the case together." Jiang Yuan dragged Liu Jinghui into the water without hesitation.
Qi Changye agreed.
Soon, Liu Jinghui and Huang Qiangmin came in together.
Liu Jinghui smiled bitterly and said, "I was planning to go home in a week or two."
"It may not be longer." Jiang Yuan smiled.
"Why, do you have any new discoveries?" Liu Jinghui was slightly surprised.
"No, but if the case cannot be solved in a week or two, there should be no hope." Jiang Yuan smiled.
"You..." Liu Jinghui was helpless. If it was a young criminal policeman, he would have scolded him for talking nonsense, but since it was Jiang Yuan, it was okay.
Qi Changye and others provided little information, but it was very crucial. Liu Jinghui finished reading it in a short time and then thought about it.
Jiang Yuan took the code book back and flipped through it.
"Now, the case is back to the idea of murder. It can be regarded as returning to the right track." Liu Jinghui sighed first, and then said: "If it is murder, what benefits can the other party get by killing Zhang Xiaoming?"
Liu Jinghui looked at Qi Changye.
"Ask me?" Qi Changye pointed at his nose.
"Yes. From your point of view. What's the point of killing Zhang Xiaoming?" Liu Jinghui paused and explained: "The normal way of plotting was discussed by the previous task force, including the layoffs and Zhang Xiaoming's personality. They also discussed emotional killings, or previous feuds, that is, the Zhang family, which was not fully discussed."
My dear, there is more to this chapter. Please click on the next page to continue reading. The latter is more exciting!
"Killing him will have no effect on the Zhang family. At least as far as I know, it should have no effect." It was not easy for Qi Changye to give this answer in the first sentence. It was also because he trusted Jiang Yuan very much that Qi Changye gave this answer.
Qi Changye also knew that this answer would directly affect the investigation direction of the task force. If he didn't want to take responsibility, he didn't have to say it. However, from the perspective of efficiency, eliminating this false option is very effective.
Huang Qiangmin understood it as soon as he heard it, and whispered a few words in Jiang Yuan's ear.
Liu Jinghui continued: "Now if we exclude these reasons, do we have reason to believe that Zhang Xiaoming's death is related to spies?"
"What do you think?" Qi Changye asked back.
"I think it is related." Seeing Qi Changye's efficiency, Liu Jinghui also answered very efficiently, saying: "There are two reasons. First, the murderer Li Dianzhong has no other reason to kill Zhang Xiaoming, and no other motive for killing. Second, judging from his actions, he should want to find something from Zhang Xiaoming. What can Zhang Xiaoming have in his hands that is worth him, an intelligence officer, to look for?"
"Intelligence? Zhang Xiaoming has no access to any intelligence." Qi Changye shook his head slightly.
"If it's not for intelligence..." Liu Jinghui just paused for a moment, without thinking too much, and said: "Could it be to protect himself?"
"What do you mean?"
"Zhang Xiaoming may have discovered something, or got something in his hand, forcing them to take it back." Liu Jinghui said this, spreading his hands and said: "I don't know much about spies, but we have actually discussed this topic before. If you want to kill Zhang Xiaoming directly, there is no need to kill him at his home, and there is no need to do it at this time and in this way. Therefore, there must be something in Zhang Xiaoming's home that the other party wants to take away."
Qi Changye is not unwilling Agreeing with Liu Jinghui, he just said, "You just said it was a murder case."
"The person must be killed and the things must be taken away. Now it seems that I think this is more reasonable." Liu Jinghui then talked about the injured part of Zhang Xiaoming, and then said, "Li Dianzhong is a professional. If he doesn't want to kill people, he should have other means to deal with Zhang Xiaoming. Including wearing a mask, which can also avoid direct conflict. Ordinary thieves can't think of this kind of thing, and professionals always have some means to deal with it."
"What you said makes sense... Then, what do they want?" Qi Changye paused, and then said to himself: "Did they get it?"
