Jiang He looked at the note that was still on the table, and picked it up: "As you can imagine, there are no fingerprints on the note, and there are fine fluffy fibers around the note. The strip was cut from a larger piece of paper. The killer probably used a ruler or something to jam the paper and ripped it off."

"I have 60% confidence that this note was cut from A4 paper. Most of the usual printing paper is A4 paper. The words on the note are in bold and the font size is size 4. Set up. And the note is not big, it’s easy to throw away and it’s not easy to spot.”

Mr. Shao put his tea jar on the table and said, "It's true, on the way here, Guan Deng has called the surveillance at the gate of the Public Security Bureau. People on the side of the road are coming and going, I don't know the note. When did it fall on the ground, and when a policeman was about to pick up the note and throw it in the trash, he accidentally saw the words on the note."

"Actually, this is a very random approach." Jiang He said, "There is a high chance that this note will not be seen. Deng Xiangyu's death method is strange. If it was done by the same person, the two The level of sophistication of the second killer did not match."

"By the way." Xu Yiman clapped his hands, blinked his eyes, and said, "When Deng Xiangyu died, didn't someone leave a note? The note is still at the Municipal Bureau, so I'll take it now. "

With that said, Xu Yiman pushed open the door and left the conference room.

After a moment, two notes were placed in front of the three people.

"It definitely wasn't written by one person." Elder Shao and Jiang He said in unison.

"Tell me what you think." Elder Shao looked at Jiang He.

Jiang He looked at the two pieces of paper and said, "The textures of the two papers are different, one is A4 paper, but the other is obviously letter paper."

"Letter paper?" Jiang He suddenly muttered to himself when he said this.

"Is there any problem with the stationery?" Xu Yiman asked.

Jiang He grabbed the letter and stared at it in the sun. Compared with A4 paper, this letter was slightly thinner, and it had vertical lines, so it belonged to old-fashioned letter paper. The sunlight filtered through the stationery, became hazy, and shone on Jiang He's face.

"Also, the newly discovered note is printed, and the writing on the letter is written with a pen."

Jiang He patted the letter on the table and said, "Because this kind of letter is not common, and coupled with the environment at the dumping site, I think we will soon be able to find out who the person who dumped the body was."

Shao Lao took a sip of tea and played with the tea jar in his hand. After seeing Jiang He's words, he continued Jiang He's words and said, "Yes, although I haven't been to the scene, but from this note , we can see a lot of things.”

"For example, this person must be a literate person." Shao Lao put the tea jar aside and said, "Nowadays, few people use this kind of formal letter paper, especially since the word is not written with a gel pen. , but written with a pen, the font is slightly immature ~ tender, but it is better than most people. This shows that this person has been practicing calligraphy for a while. "

"Finally, look at the words on the note. This is a kind of wording and sentence selection that is close to classical Chinese, but there are one or two words that do not conform to the norms of classical Chinese. It can be seen that this person is interested in ancient Chinese and reads a lot, but he does not There hasn't been an in-depth study of it."

"So we are looking for a man, who is between thirty and forty years old, has a decent job, a good family, and has his own study. This man likes quietness, does not want to join in the fun, and is introverted. . Education should be above the undergraduate level.”

After saying this in one breath, Shao Lao reached out and took the tea jar again, and then took a sip of tea.

Jiang He has never considered the problem from this angle, but this has always been Jiang He's practice, that is, he never analyzes the problem from this seemingly metaphysical angle, he only pays attention to solid evidence.

But Mr. Shao mainly focuses on psychology. Mr. Shao believes that as long as there are traces of subjective initiative, one can always dig deeper into the reasons behind it.

Shao Lao continued: "So go and inform the criminal police in charge of this matter, narrow down the scope, and find someone who fits such a personality."

Xu Yiman nodded, and while sending a text message to Captain Liu, she asked suspiciously, "By the way, why can't you see Guan Deng's figure? What is Guan Deng doing?"

"I gave him a special assignment."

"Special mission?" Xu Yiman pouted: "So mysterious."

"Say that Cao Cao and Cao Cao are here." Veteran Shao took out his mobile phone: "Guan Deng told me that his investigation has already gotten some attention."

"Let's go, we will meet with Guan Deng." Shao drank all the tea in his teapot.

When the three found Guan Deng, Guan Deng was still beside the computer. He seemed to be playing the piano. His fingers were jumping rapidly on the keyboard. The mechanical keyboard made a "crackling" sound. It seems to be very pleasant.

"How's it going?" Shao asked.

Guan Deng glanced back subconsciously and wanted to speak, but seeing three people staring at him, Guan Deng's words had already reached his mouth, but he couldn't say anything. He blushed and looked very embarrassed. Finally, he turned his head away, didn't dare to look at everyone, and typed what he wanted to say on the computer screen.

"Old Shao, you asked me to investigate Deng Xiangyu's information. I have already checked almost all of it. Deng Xiangyu's parents are farming in the countryside, and Deng Xiangyu usually lives in a relative's house in Longcheng. To be precise, it is Deng Xiangyu's third concubine's house. Judging from the logs that Deng Xiangyu posted on QQ space that only he can see, Deng Xiangyu's third aunt is not good to him."

"Deng Xiangyu's third aunt works in the city. The third uncle runs a big car and is usually not at home. Her family's conditions are moderate, and she has a daughter who is in the second year of junior high school. According to the analysis of Deng Xiangyu's log in QQ space, Deng Xiangyu's third aunt is She has never beaten or scolded Deng Xiangyu, but she often said bad things about her parents in front of Deng Xiangyu, and often said when educating her daughter, for example, "If you don't study hard, you will be like your aunt and uncle. land's words."

"Deng Xiangyu's younger sister also showed a high-level look all the time, humiliating Deng Xiangyu all day long. Deng Xiangyu didn't want to cause trouble to his parents, but he lived in these insults all the time. In his diary, he repeatedly expressed that he wanted to escape. I want to leave this world."

Xu Yiman sighed and said, "People are under the eaves and have no ability to escape, so they can only constantly bear such pressure."

Guan Deng is still typing, and he is typing fast:

"He was very depressed, but he and his sister were in the same school, and he couldn't find anyone to express his sorrows in his heart. He didn't dare to speak ill of his third aunt and his sister. The reason is that others are not good. But his third aunt's seemingly unintentional remarks turned into cruel remarks in front of him. He knew that his parents were useless, and he felt that he was also useless. "

"He couldn't find a place to vent, so he had to indulge in the Internet. And soon, Deng Xiangyu's grades plummeted, from the fast class when he first entered the school, all the way back to the slow class. No one knows what happened to him. , and no one knows his inner distress, he tried to talk to his parents, but his parents never cared about it and couldn't control him at all."

"Deng Xiangyu finally broke the jar. From a certain day in the second year of junior high, Deng Xiangyu lost the habit of writing a journal. Since then, most of the reposts in his QQ space are decadent, depraved, and even sexual articles, videos, etc. .And from the second half of the second semester of junior high, he came into contact with S~M."

"Sex~abuse?" Jiang He asked.

Guan Deng continued typing: "Yes, judging from his QQ, he added a lot of people in this circle, and he discovered the M attribute in himself."

Shao Lao sighed and said: "Lack of a sense of security and existence for a long time makes him very eager to find a strong person like his sister or mother to control his life. He is sensitive and fragile, and in extreme cases , he can do anything to please others and satisfy his distorted and lowly existence."

"He really lacks love." Xu Yiman said: "And he is only about sixteen years old this year."

"This kind of emotional backlog is basically formed before the age of six." Shao Lao said: "According to Freud's theory, childhood has a great impact on a person, and the root of all mental problems is , can be traced back to childhood. That is to say, maybe from birth, his parents did not take good care of him, just to make a living. "

Jiang He asked Guan Deng, "Then you mean, does he have some very strange hobbies?"

Guan Deng typed on the screen: "He has been in contact with the queen on the Internet many times, and he has also been trained several times. He has always lied that he is over eighteen years old, and just after he died The night before, he once made an appointment with a queen for a tune-up time."

"They made an appointment to conduct training at a small hotel. I checked the small hotel on the Internet, but it actually didn't have a business license and was a black shop."

"Who proposed to tune in there?" Shao Lao asked.

"The lady." Guan Deng called out.

"Have you found any information about this woman?" Shao Lao asked again.

Guan Deng shook his head and said, "The woman's QQ should be bought casually, without leaving her real identity. But I hacked into her account and found that she had an appointment to continue to that small hotel tonight. ."

"Very good." Shao Lao said: "I'm going to capture this queen, she might know something."
