"The suspect is a woman, between the age of 24 and 30, has the experience of military, police or sports athletes, has not received higher education, but has high IQ and high EQ. He is good at disguise and forbearance, and has certain anti-investigation ability. He may have a crush on the relationship with the deceased Tang Jianwei, shy, cowardly appearance, decisive, firm inner self, and a tendency to force thinking. He should have close contact with Tang Jianwei and Xiao Zhenqin in specific occasions. It is recommended to investigate people who have intersections with the two, such as Xiao Zhenqin's close friends and female parents of students from top educational institutions."

After reading it, Chenchen said, "Why are you sure you are a woman?"

Wang Lu said: "First, poisoning is in line with the characteristics of a woman committing the crime. Although the murderer imitated Xiao Zhenqin's method of committing the crime, the characteristics of the crime will not change much. If it is a man, even if it is a retaliatory murder, it should be in his own way, rather than just imitating it. The reason for imitating the murder is also because of his love for Tang Jianwei!"

Chen Chen nodded slightly. Although he had other thoughts on this, Wang Lu was not wrong.

"Second, from the video on the floor where Xiao Zhenqin lives, there is indeed such a woman, and this woman was the last person to enter her family before Xiao Zhenqin died. This video also confirms this."

He smiled deeply and said, "Is there a third?"

"Of course, the murderer's technique is very delicate, especially the interpretation of flower language is very accurate. Those flower languages ​​represent revenge. This is also in line with the universality of female thinking traits."

Chen Chen nodded again, and he also began to feel that Wang Lu's analysis was correct.

He asked again, "How did you determine the professional characteristics of the murderer?"

Wang Lu replied: "After understanding of Xiao Zhenqin, she is a woman who pays great attention to her appearance, especially her figure. She not only asked Tang Jianwei to go to the gym, but she is also a regular visitor in the gym. At first, our judgment was that an acquaintance committed the crime, which was poisoned by her unknowingly. However, the autopsy report showed that she was poisoned after fainting, and she was very likely knocked out by someone. Then the person who took action should have certain fighting abilities."

Chen Chen said: "If that person is really an acquaintance, she can knock her out while she is not paying attention, right?"

"If it is normal, there is such a possibility, but my Captain Shen, don't forget that Xiao Zhenqin received the intimidation call that day. After receiving the call, she was like a frightened bird, and even packed her luggage and prepared to leave. Think about it, even if she was a real acquaintance at this time, she would be deeply alert. There was no trace of a fight at the scene of the crime, which means that the other party should have knocked her out with one blow. This shows that the person who took the action was very professional, and I wouldn't have done it anyway."

He narrowed his eyes and finally nodded.

"As for the murderer's shyness, he was also considering this point of view. If the murderer didn't usually give Xiao Zhenqin the feeling like this, I think even if he was an acquaintance, Xiao Zhenqin wouldn't open the door for her easily and let her enter the house, right? But from the murderer's attack, he was very decisive and firm. This is a woman who is soft on the outside and hard on the inside. Needless to say, compulsive thinking is, this is the prompt you gave us."

"Okay, then that's it. Let Lao Xiao and the others check it according to this profile. If there is a scope, I believe the murderer will soon surface."

After Chenchen said that, he picked up a file on the table and read it.

Wang Lu tilted her head and looked at the heavy person: "Why did I realize that your attitude towards me today is a bit wrong!"

“Is there any?”

"Yes! You don't seem to be willing to talk to me more."

I was shocked. Did I really act so directly?

Actually, it’s not. This is just Wang Lu’s intuition. Of course, women’s intuition is often very accurate.

Chen Chen said: "The case has been busy these days, and the rest is not very good, so the mood is not high. As for what you said, it doesn't exist at all."

"Okay, you treat me to lunch at noon. I'm going to Chaobainian to eat hotpot!"

After saying that, Wang Lu turned around and left without waiting for Chenchen to agree.

He felt helpless in his heart. He didn't understand Wang Lu's thoughts. He had never thought about thinking about his own affairs before, but now it was because the note from the old beggar also left a shadow in his heart.

Xiao Qiushui and Luo Sen came to Dingge Education Institution again.

Pan Jianwen was not there, but he told the secretary that he would try to meet any requirements of Xiao Qiushui and others.

He also hopes that the police can solve the case as soon as possible, otherwise it will not be a good thing for Dingge Education.

"Please find all the information about the parents of Tang Jianwei's students over the years," said Xiao Qiushui.

The secretary responded, put down two cups of tea and went there quickly.

"Team Xiao, the scope will be too wide if you follow this investigation."

Xiao Qiushui shook her head: "On the contrary, at least Director Wang's close-up has set a scope for our investigation. Although Tang Jianwei has taught many students over the years, there should not be too many parents of students who have really dated him, especially female parents. In fact, we have mastered it. This time we came to see if there will be any omissions. As for Xiao Zhenqin, there are even fewer close friends. Xiao Zhenqin is a person who has high requirements for quality. Even if she makes friends, she is not casual."

Rosen said: "I think the murderer is probably a man."

Xiao Qiushui smiled and said, "Didn't you say you should check it out your own way before? How about it, are there any results?"

Luo Sen was speechless after a sentence. He did investigate according to his own ideas, but he found nothing at all.

Pan Jianwen's secretary brought the student information, Xiao Qiushui and Luo Sen sorted it out again, and then called with several teachers who had attended classes with Tang Jianwei and asked carefully. In the end, there were no new discoveries. The two women who were the most suspected were the two women, Fan Xuan and Lu Xiuying.

After leaving, Luo Sen said, "I just said it's useless to come again. Except for Fan Xuan and Lu Xiuying, the relationship between other students and Tang Jianwei is very ordinary. As for Fan Xuan and Lu Xiuying, they don't have time to commit crimes at all. In addition, they shouldn't do such stupid things because of love. Fan Xuan lives very well, and Lu Xiuying is even more a show-off. As long as she is a young man, she likes to tease her, and it's even more impossible to kill people for love."

Xiao Qiushui said: "It seems we have to focus on Xiao Zhenqin's close friends."

Luo Sen said: "We have had contact with her close friends, and one of them said that Xiao Zhenqin never brought Tang Jianwei with her when she was having a party with them, but she was worried that she would be snatched by her close friends. No wonder she herself was just prying someone's corner, so she must be on guard against her own."

Xiao Qiushui didn't think so: "She may not be able to bring big gatherings, but I don't believe that none of her close friends have ever seen Tang Jianwei. Everyone has one, two people he thinks he can absolutely trust without guarding. And it is often such a person who can best sell him more thoroughly."

Luo Sen glanced at Xiao Qiushui: "Captain Xiao, what you said makes people feel scared."

Xiao Qiushui gave him a blank look: "What are you thinking? Didn't Shen Da say that before when he taught you classes? People like Xiao Zhenqin who have received Western education are different from many people when it comes to getting along with others. For example, many of us are very attentive to make friends at the beginning, brothers, and treat others as our own people with all their hearts. Then during the contact process, we will slowly discover that this person did not really treat you as a buddy or a brother. Gradually, you will gradually get farther and farther away.

But people like Xiao Zhenqin are different. At the beginning, they are cautious and wary about people who are dating. First, they are skeptical, and always feel that others will have some purpose in getting close to her. Then during the dating process, they slowly find out whether the other party is really worthy of dating or even giving. The former type of people goes from affirmation to suspicion, and the latter type of people goes from doubt to affirmation. The latter type of people is amazing. Once the person is affirmed is worthy of his trust, then he will believe it without doubt."

Luo Sen nodded, remembering that Shen Chen did talk about this during a business training, which was about the differences in East and West culture and the impact of Western education on psychology. There was no such training in the team before, and it was only after Shen Chen came.

However, the colleagues in the team really like Shen Chen's training method, at least not boring. He can combine it into many practical cases. To put it bluntly, the training done by Shen Chen is just an extension of criminal psychology.

Xiao Qiushui called Xu Jing and Xu Jing must know more about Xiao Zhenqin's close friends.

Xu Jing cooperated very well. As soon as she received the call from Xiao Qiushui, she made an appointment with Xiao Qiushui to meet at a small coffee bar next to the TV station. When Xiao Qiushui and the others arrived, Xu Jing was already waiting there.

"Reporter Xu Da, did you not delay your work, right?" Xiao Qiushui greeted with a smile.

Xu Jing gave him a blank look: "If I say delay, will it disappear?"

Xiao Qiushui was a little embarrassed, and Luo Sen hurriedly helped him out: "We have no choice. You are familiar with Xiao Zhenqin. We just want to ask if Xiao Zhenqin has any friends who are very fun and even trustworthy?"

Xu Jing narrowed her eyes: "You should be suspicious..."

Before Xu Jing finished speaking, Luo Sen interrupted her: "Reporter Xu, you also know that we have our discipline. It doesn't mean we doubt anything when we look for you. It's just a routine inquiry."

"Tsk, I'm still playing this with me." Xu Jing glared at Luo Sen with some dissatisfaction. Luo Sen couldn't say anything else, but just smiled.

Xu Jing said: "She does have two very good friends, and her relationship is much better than us and her. However, one of them was abroad and the last time she returned to China was two years ago. The other was in Lincheng. She used to be an athlete from the fencing team of Lincheng Sports School. She has retired now, but she stayed in the sports school. She is now the coach of the fencing team, named Tang Mei."

When I heard that the woman was an athlete in the sports school, Xiao Qiushui and Luo Sen's eyes lit up at the same time.

It seems to match Wang Lu's profile, a sports athlete!

Xu Jing took their expressions into his eyes: "What do you mean?"

Xiao Qiushui said, "No, nothing, think about it carefully, is there any more?"

"It's gone. If you have to find another one, it's me. We should be saying anything."

Xu Jing was a little unconfident when she said this, and added: "After all, I have known her and I haven't known each other for as long as Tang Mei. She had a good relationship with Tang Mei before going abroad."

"oh?"

"She and Tang Mei are old neighbors, both in the same school as primary and junior high schools, and Tang Mei has always taken good care of her. Tang Mei is simply a tomboy in front of her."
