The current difficulty is that the four deceased do not know each other, have no contact, and the connection with the deceased is very weak, it is difficult to find the same object from the chat history, and it is impossible to locate the murderer.

Secondly, the murder weapon has not yet been determined, and it is impossible to find the location of the murderer through the means of obtaining it.

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

After Mr. Ji summarized these, let everyone continue to express their thoughts.

"I'll start by refining the previous profile and see if I can help you open your mind. Chen Chen volunteered to think of something.

"Male, 26 to 30 years old, born into a scholarly family, engaged in writing-related work, with good literary accomplishment and personal accomplishment. Married, divorced, widowed, belonging to the middle and high-income group, stable job, car, house and savings. Four years ago, I suffered from azoospermia, and the seeds of inferiority germinated in my heart, and I am usually introverted and shy in real life. ”

"There may be another kind of face on the Internet, humorous and eloquent, and it is easy to win the favor of girls. He is about 175 tall, and his body is slender and thin. Locals of the provincial capital, who do not live with their parents, have their own private homes. ”

Chen Chen paused for a moment when he said this: "Married, divorce and widowhood are excluded." ”

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

"The fact that the murderer had his own place to live, and was not a daring man, but did not bring the deceased back to his own home, indicates that there were 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 my country's marriage law, a man can only get married at the age of twenty-two, and 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 condition of most men, and it is impossible to be more than 30 years old. ”

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

"I have a question, how did you deduce your figure?" Liu Minmin asked as she wanted to keep up with her master's pace.

Chen Chen didn't enter a state of deep thought, glanced at her and replied: "The psychological state of the deceased, if the netizen I saw was a man with five big and three thick, he would instinctively be defensive, and he would not be so easily taken away by stunning." Judging from the murderer's use of sleeping pills, in the face of several girls who are not very tall, his self-confidence is insufficient, and it is obvious that he will not be a strong person. ”

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

"In addition, I suspect that the murderer's physical condition has changed during the year, and there are two possibilities. First, the azoospermia was cured, but the psychopathology was not adjusted, so the murderer did not dare to really sexually assault when he killed so as not to leave evidence; ”

"This is a point of concern, but last year's case has not been found, and it is possible that the murderer has changed since last year. Ying Mingyu felt that this was a good range for screening, "The side that is looking for cases and informs them to pay attention to the people whose conditions have changed accordingly in the past two years." ”

Combined with the age and work of the murderer, the suspect should be screened from the case, and then the elimination may be a little slower, 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 portrayal of the suspected murderer, what will be around him, is it a possible murder weapon?" Fang Jinshi was asking his fiancé.

Fan Hua was very embarrassed, he hadn't had time to talk to her yet.

"To be honest, we tried all sorts of possibilities, but we couldn't find a match. In the past two days, Zhang Ke and I also went to the thrift market to shop, and there was no clean braided belt in that place, which did not match the strangulation marks of the deceased. ”

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

"From here, maybe I can open a breakthrough, and I'll go to the hospital later to ask for a shallow opinion, and I'll let you know when there's news. Ying Mingyu nodded to Teacher Ji.

"That's a shallow problem. Teacher Ji agreed.

"I'm going too, I'm here to see shallow. Chen Chen immediately raised his hand.

"Let's talk about the first case, what can be found so far is the Wei Zishan case, I suggest that we should visit her in more detail, the people who could contact her at that time may be very close to her. Luo Yin pulled the topic back, he didn't want the meeting to end here.

"Agreed, I'll follow up with you. Fang Jinshi agrees with this idea.

According to the age limit inferred by Chen Chen, plus the fact that both of them occurred in the provincial capital, the probability of being the first case four years ago is very high, and the profile of the murderer being a local also comes from this.

"Well, I don't think we've done much to mark this case. Approaching the end, Wang Tao complained about himself.

Ying Mingyu stared 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 things in the belongings of these deceased, which belong to the murderer." ”

"I really didn't expect this! Lian soldiers, go, kill one and go back to the pistol and take a look!"

Before leaving, I didn't forget to take away my rival, and I had a strategy. Ying Mingyu shook his head and was about to take Chen Chen to set off to see Qianqian, and caught a glimpse of Du Xiuxiu as if he had something to say to Teacher Ji, and leaned over and was waiting for them to finish.

"Teacher, I want to stay here and learn from Dr. Fan, who has a lot of practical experience that I find difficult to encounter in a few big cases every year. "Most of the cases they follow up are serial cases, and the deceased are often subjected to cruel methods such as dismemberment and frying, and it is one thing that the autopsy is difficult, and she has little contact with other types of autopsies, so she is indeed very inexperienced.

When dealing with the same type of autopsy, it is easy to be limited by inherent experience, and there is no better way to help the criminal investigator provide a gripper. In Jin Yang's case last time, she didn't expect that there would be that way to determine the murder weapon.

Teacher Ji looked at this delicate apprentice: "Fan Hua and Jin Shi are together, they thought everyone knew, so they didn't say anything special, don't you know yet, right?"

Du Xiuxiu was stunned.

This world is really interesting, and there are many people in and out of the group who like this girl, but she will pick the wrong person every time. Last time it was Ying Mingyu, this time it's Fan Hua.

In comparison, picking Fan Hua is a suitable choice, and last time it should have been purely a girl's dream. It's a pity that the right choice doesn't necessarily lead to a better future, she is not only late, but also not the type that the other party likes.

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

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

It's a pity that there is a big mouth who walks slowly and listens to this, and soon reports it to his superiors, which is naturally a package.

Fang Jinshi didn't expect that she would be absent for a few days, and Fan Hua would also cause her a romantic debt.

Ying Mingyu took Chen Chen to the hospital to see Lu Qianqian, and the time he arrived was eight o'clock in the evening, which was quite early, so he specially bought some snacks.

As soon as Chen Chen went, he sat down to prepare for dinner, which he bought by the way on the way to come just now.

"Haven't you eaten yet?" Lu Qianqian pulled someone to sit down, took a small snack and wanted to feed it.

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

Lu Qianqian nodded again and again, and thanked Chen Chen with a smile.

"It's been okay these days. By the way, it's not like it's done, I'll take a look. Ying Mingyu wanted to go around the back of the drawing board, but was grabbed by the arm.

"What's the hurry, I'll see later. ”

"Also, my wife is much more beautiful than a painting. ”

Lu Qianqian realized that Ying Mingyu had noticed her thoughts, and glanced at Chen Chen, the boy pretended not to hear, and her face was still a little hot.

I haven't seen him for a week, she misses him very much, she just wants to see him more, is this too much to ask, and he still wants to demolish her.

"Is the case tricky? Now you have a clue?" Lu Qianqian also wanted to say something else, but there was an outsider here, and she was still thin-skinned.

"It's okay, I'm not here to find foreign help, I still can't leave 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 his laughter, coughed and said: "Then give me the photo, come up with it as soon as possible, you can go back and continue to check, you always worry about the province, you can't eat well." ”

Ying Mingyu put the picture she brought into her open palm, and replied with a light smile: "I'm not in a hurry, what else can't I eat when I see you." ”

He would also coax her verbally, Lu Qianqian took the photo and looked at it, she didn't understand it very well.

Fan Hua speculated that it was some kind of braided belt, and compared the ones on the market, they did not find the same. ”

"You're talking about that kind of slender braided belt used to pack things?" Lu Qianqian understood a little now.

"Well, have you seen it? Do you want me to add other information for you?" Although it is inconvenient to tell Lu Qianqian too much about the case, the murderer can still be revealed related to the written work.

Lu Qianqian shook his head: "Although it's not very useful now, it can still be seen, in two places." ”

Chen Chen stood up suddenly, what did these people have in their minds, Lu Qianqian didn't think of it for a quarter of an hour, and he thought of the two of them at once.

"I knew I was coming to you in the first place. Okay, I'm full, let's talk about it. Ying Mingyu threw away the lunch box and reached out to help Qianqian brush his hair.

"You can't solve the case, it's all because you don't have culture. This thickness is supposed to be a braided belt for binding books, and you can see it when you enter a book in a bookstore. However," Lu Qianqian gasped and said after selling the pass, "Another place is more common, the publishing house, I have been there a few times when I was taking over the cover picture, and they are stacked with bundles of books everywhere, which should be this thickness." ”

"I didn't think of the rest for the time being, you go back and compare and see, I'll think about it again. ”

"My wife was awesome. Ying Mingyu stepped forward and wanted to kiss one, but was pushed, "Chen Chen, you go out and wait, I still have two more words to say to Qianqian." ”

"I'm just full and want to eat, I'll see you downstairs later. Chen Chen only had envy.

Ying Mingyu saved time, immediately kissed goodbye to his lover, and went downstairs to chase Chen Chen.
