The current difficulty is that the four deceased people did not know each other and had no contact with each other. The connection with the deceased is very weak. It is difficult to find the same person from the chat records and to identify the murderer.

Secondly, the murder weapon has not yet been identified, and there is no way to find the murderer's location through the means of obtaining it.

In addition, no evidence has been found that can be used to verify the identity of the murderer. No fingerprints or DNA residues of the murderer have been found.

After Teacher Ji summarized this, he asked everyone to continue expressing their thoughts.

"Let me improve the previous profile first and see if I can help you open up your ideas." Chen Chen volunteered to help.

"Male, 26 to 30 years old, born in a scholarly family, engaged in writing-related work, has good literary accomplishment and personal accomplishment. Married or divorced, widowed, belongs to the middle-to-high income group, has a stable job, owns a car and a house.

Deposit. I suffered from azoospermia four years ago, and the seeds of inferiority sprouted in my heart. In real life, I am introverted, shy and not good at words."

"There may be another face on the Internet. He is humorous and talkative, and it is easy to win the favor of girls. He is about 175 years old, and has a slender figure. He is a native of the provincial capital, does not live with his parents, and has his own private residence.

.”

Chen Chen paused for a moment when he said this: "Married, excluding divorced and widowed."

"Why?" Bao Zhan asked casually, interrupting Chen Chen's thoughts.

"The murderer has his own place of residence, and he is not a bold person. However, he did not take the deceased back to his home, which shows that there are other people in the murderer's family."

"There is no adjustment in age?" Although Ying Mingyu knew that it was accurate to twenty-six years old, he still had objections to the upper age limit.

Chen Chen nodded affirmatively: "According to our country's marriage law, men can only get married when they are twenty-two years old. The murderer must abide by the regulations, so he must be over twenty-six years old. The mental age is low, which is in line with the situation of most men. It is impossible to be more than three years old."

Ten years old."

"I trust your judgment." Ying Mingyu still respects professionals.

"I have a question, how do you infer the figure?" Liu Minmin asked as she wanted to keep up with her master.

Chen Chen stopped thinking deeply, glanced at her and replied: "The psychological state of the deceased. If the netizen he saw was a tall and thick man, he would instinctively be defensive, and he would not be easily carried away by being stunned. From the murderer's use

Judging from the sleeping pills, he doesn't have enough self-confidence when facing several girls who are not very tall, and it is obvious that he is not a strong person."

"Oh, that's right." Liu Minmin didn't make things difficult for him anymore.

"In addition, I suspect that the murderer's physical condition has changed within this year. There are two possibilities. One is that the azoospermia has been cured, but the psychological abnormality has not been adjusted. Therefore, the murderer did not dare to commit sexual assault when killing to avoid leaving behind

Evidence; secondly, the murderer's physical condition was even worse and he could no longer complete sexual relations, so he used props."

"This is a point worthy of attention. However, the case from last year has not been found yet. It is possible that the murderer has changed since last year." Ying Mingyu thinks this is a good range for screening. "Where the case is found, notify them to pay attention."

Pay attention to people whose condition has changed accordingly in the past two years."

Combined with the murderer's age and job, we should be able to screen out the suspects from the cases. It may be a little slow to eliminate them, but there should be no mistakes or omissions.

It's just still a big project.

"Let's talk about the murder weapon. According to the description of the suspect, what would be around him that could be a possible murder weapon?" Fang Jinshi was asking his fiancé this question.

Fan Hua was in a dilemma. He hadn't had time to tell her the truth yet.

"To be honest, we have thought about various possibilities, but we have never found a match. In the past two days, Zhang Ke and I also went shopping at the flea market. There were no clean woven tapes in that place, which was inconsistent with the strangulation marks of the deceased.

.”

"The murderer used the same murder weapon four times, but it was not the same one. This shows that the murderer must often have access to such a murder weapon, either in the car or with him." Fang Jinshi thought about it for a moment, but had no answer.

"Maybe we can open a breakthrough from here. I will go to the hospital later to ask for Qianqian's opinion. I will let you know when there is news." Ying Mingyu nodded to Teacher Ji.

"That'll be troublesome for Qianqian." Teacher Ji agreed.

"I want to go too. I came to see Qian Qian." Chen Chen immediately raised his hand.

"Let's talk about the first case. The one we can find so far is the case of Wei Zishan. I suggest we visit her in more detail. People who had access to her at the time may have been very close to her." Luo Yin brought the topic back. He didn't want the meeting to happen.

So far.

"I agree, I will follow up with you." Fang Jinshi agreed with this idea.

According to Chen Chen's inferred age limit, and the fact that both cases occurred in provincial capitals, there is a high probability that it was the first case four years ago, and this is where the profile of the murderer as a local came from.

"Hey, I feel like our trace inspection has made little contribution to this case." When the show was about to end, Wang Tao complained to himself.

Ying Mingyu looked at Du Xiuxiu when he said this, and found something for him, "Since Chen Tongtong's belongings are missing a notebook, you might as well look for it. Maybe there are more in the deceased's belongings."

What comes out belongs to the murderer."

"This is really unexpected! Company soldiers, let's go, kill one of them and go back and take a look!"

Before leaving, he didn't forget to take his love rival with him. He had a strategy. Ying Mingyu shook his head and was about to take Chen Chen to see Qian Qian. He caught a glimpse of Du Xiuxiu who seemed to have something to say to Teacher Ji. She walked over and was waiting for them to finish.

"Teacher, I want to stay here and learn from Dr. Fan. A lot of his practical experience is difficult for me to encounter in a few major cases every year." Most of the cases they follow up are serial cases, and the dead are often dismembered.

, frying and other cruel methods make autopsy difficult. She has rarely been exposed to other types of autopsies, and her experience is indeed lacking.

When dealing with the same type of autopsy, it is easy to be limited by the inherent experience and cannot think of better ways to help the criminal investigation. In the case of Jin Yang last time, she did not expect that there could be such a way.

Determine the murder weapon.

Teacher Ji looked at this delicate apprentice: "Fan Hua and Jin Shi are together. They thought everyone knew about it, so they didn't say anything in particular. You don't know yet, do you?"

Du Xiuxiu was stunned.

This world is really interesting. There are many people in the group and outside the group who like this girl, but she always picks the wrong person. Last time it was Ying Mingyu, this time it is Fan Hua.

In comparison, picking Fan Hua is a suitable choice. The last time should be purely a girl's dream. Unfortunately, the right choice may not lead to a bright future. Not only did she come late, but she is not liked by the other party.

type.

"Anyway, there are no other cases. It's a good idea to stay here and learn more." Teacher Ji didn't say any more and patted the little girl on the shoulder.

"Yes, teacher." Du Xiuxiu was secretly glad that she told the teacher about this first instead of going to Fan Hua directly.

It's a pity that there was a big talker who walked slowly and heard about this matter, and quickly reported it to his superior, who was naturally Bao Zhan.

Fang Jinshi didn't expect that Fan Hua would incur a romantic debt for her during her absence for a few days.

Ying Mingyu took Chen Chen to the hospital to see Lu Qianqian. They arrived at eight o'clock in the evening, which was still early, so he bought some snacks.

As soon as Chen Chen arrived, he sat down and prepared for dinner. He bought some on the way here.

"Have you not eaten yet?" Lu Qianqian asked the person to sit down, took some snacks and wanted to feed him.

"This is yours, I bought it... Let's get down to business after eating." Ying Mingyu was still working, but was interrupted by Chen Chen and had to put it down first.

Lu Qianqian nodded repeatedly and thanked Chen Chen with a smile.

"How have you been these past few days? By the way, it's not that the painting is done, let me take a look." Ying Mingyu wanted to go behind the drawing board, but someone pulled his arm.

"What's the hurry? We'll see later."

"Yes, my wife is much prettier than the painting."

Lu Qianqian realized that Ying Mingyu had noticed her thoughts and glanced at Chen Chen. The boy pretended not to hear, but she still felt a little hot.

They haven't seen each other for a week, and she misses him so much that she wants to see more of him. Is this too much to ask for, and he wants to expose her?

"Is the case difficult? Do you have a clue now?" Lu Qianqian also wanted to say something else, but with an outsider here, she was still thin-skinned.

"It's okay. I'm not looking for foreign aid. I can't do it without you." Ying Mingyu is thick-skinned and doesn't care about the existence of a third party at all.

Lu Qianqian tried hard to hold back her laughter, coughed and said, "Then give me the photo. If you think of it early, you can go back and check it out. This saves you from worrying about it all the time and you can't even eat well."

Ying Mingyu put the picture he brought into her open palm and replied with a smile: "I'm not in a hurry, there's nothing I can't eat after seeing you."

He would also coax her verbally like this. Lu Qianqian took the photo and looked at it, but she didn't quite understand.

"Fan Hua and the others speculated that it was some kind of braided belt. They compared the ones on the market and couldn't find anything consistent."

"Are you talking about the kind of slender braided belt used to pack things?" Lu Qianqian understood a little better now.

"Well, have you seen it? Do you want me to help you add other information?" Although it is not convenient to tell Lu Qianqian too much about the case, the murderer and the writing work can still be revealed.

Lu Qianqian shook her head: "Although it's not very useful now, you can still see it in two places."

Chen Chen stood up abruptly. Lu Qianqian unexpectedly thought of what they had in their minds in just a quarter of an hour, and she even thought of two things at once.

"I knew I would come to you from the beginning. Okay, I'm full, let's talk quickly." Ying Mingyu threw away the lunch box and reached out to brush Qian Qian's hair.

"You can't solve the case because you are uneducated. This kind of thickness should be the braiding tape used to bind books. You can see it in the bookstore when you enter the book. However," Lu Qianqian gasped for breath, and after a while, she said

, "Another place that is more common is the publishing house. I have been there several times before when I was doing the cover drawings. They have piles of bundled books everywhere. They should be of this thickness."

"I haven't thought of anything else yet. You guys can go back and compare and I'll think about it again."

"My wife is great." Ying Mingyu stepped forward and wanted to kiss her, but was pushed back. "Chen Chen, please go out and wait for a while. I have two more words to say to Qian Qian."

"I just want to eat when I'm full. I'll see you downstairs later." Chen Chen could only feel envious.
