Original sin

"The criminal suspect is a female, between 24 and 30 years old, has experience in the military, police or sports athletes, has no higher education, but has high IQ and EQ. She is good at disguising and forbearance, and has certain anti-investigation capabilities. The relationship with the deceased Tang Jianwei may be a secret love relationship, with a shy and cowardly appearance, a decisive and resolute interior, and a tendency to compulsive thinking. He should have had close contact with Tang Jianwei and Xiao Zhenqin on specific occasions. It is recommended to start with the two Conduct investigations on people who have similarities with each other, such as Xiao Zhenqin's close friends and female parents of students in top-tier educational institutions."

After reading it, Shen Chen said, "Why are you sure it's a woman?"

Wang Lu said: "First, poisoning is in line with the characteristics of women committing crimes. Although the murderer imitated Xiao Zhenqin's method of committing crimes, the characteristics of committing crimes will not change much. If it is a man, even revenge killings should be He will follow his own way, instead of blindly imitating, the reason for imitation killing is also because of his love for Tang Jianwei!"

Shen Shen nodded slightly. Although he had other thoughts on this point, what Wang Lu said was not wrong.

"Secondly, from the video on the floor where Xiao Zhenqin lives, there is indeed such a woman, and this woman was also the last person to enter Xiao Zhenqin's home before she died, and this video also confirms this. "

Shen Chen smiled and said, "Is there a third one?"

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

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

He asked again: "Then how did you determine the professional characteristics of the murderer?"

Wang Lu replied: "After getting to know 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 was also a frequent visitor in the gym. At first we judged that it was an acquaintance who committed the crime. , she was poisoned unconsciously, but the autopsy report showed that she was poisoned after she fainted, and she was most likely knocked unconscious. Then the person who shot, Should have some fighting ability."

Shen Chen said: "If that person is really an acquaintance, he can knock her out when she is not paying attention, can't he?"

"If it is normal, there is indeed such a possibility, but my captain Shen, don't forget that Xiao Zhenqin just received a threatening call that day. After receiving the call, she was as frightened as a bird, and even packed her luggage and prepared to leave. You Think about it, even if she is really an acquaintance at this time, she will be deeply on guard. There is no trace of scuffle at the scene of the crime, which means that the other party should have knocked her out with one blow, which means that the person who shot it is very professional, anyway Instead, I couldn’t do it.”

Shen Chen narrowed his eyes, and finally nodded.

"As for the murderer who looked shy and cowardly, I also considered it from this point. If the murderer didn't give Xiao Zhenqin such a feeling, I think even if he was an acquaintance, Xiao Zhenqin would not give her that easily under the circumstances. Open the door and let her enter the house? But judging from the murderer's actions, he is very decisive and resolute. This is a woman who is soft on the outside and strong on the inside. Needless to say, obsessive thinking, this is the reminder you gave us."

"Okay, let's leave it at that. Let Lao Xiao and the others investigate according to this profile. With the scope, I believe the murderer will surface soon."

After Shen Chen finished speaking, he picked up a file on the table and read it.

Wang Lu tilted her head and looked at Shen Shen: "How did I find out that your attitude towards me today is not right!"

"Have it?"

"Yes! You don't seem to want to talk to me much."

Shen Shen was startled, did he really behave so directly?

Actually not, this is just Wang Lu's intuition. Of course, women's intuition is often very accurate.

Shen Shen said: "I've been busy with the case these days, and I haven't had a good rest, so I'm not in a good mood. As for what you said, it doesn't exist at all."

"Okay, you invite me to dinner at noon, I'm going to Chaobai to eat small hot pot!"

After Wang Lu finished speaking, she turned around and left without waiting for Shen Shen to agree.

Shen Shen felt a little helpless in his heart, how could he not understand Wang Lu's thoughts, he had never thought about his own affairs before, but now it was because the old beggar's note also left a shadow in his heart.

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

Pan Jianwen wasn't there, but he told his secretary that no matter what Xiao Qiushui's request was, he would try his best to meet it.

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." Xiao Qiushui said.

The secretary responded, put down two cups of tea and hurried away.

"Captain Xiao, according to this investigation, the scope is too wide."

Xiao Qiushui shook his head: "On the contrary, at least Director Wang's feature set a scope for our investigation. Although Tang Jianwei has taught many students over the years, the parents of students who have really had close contacts with him, especially women There should not be too many parents. In fact, we have already mastered it. This time, we are here to see if there are any omissions. As for Xiao Zhenqin's close friends, there are even fewer. Xiao Zhenqin is a person who has high requirements for quality. Even if it is making friends, she is not casual."

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

Xiao Qiushui said with a smile: "Didn't you say to investigate in your own way before? How is it? Is there any result?"

One sentence made Rosen speechless. He did investigate according to his own thinking, but found nothing at all.

Pan Jianwen's secretary brought the student materials, Xiao Qiushui and Luo Sen sorted it out again, and then called several teachers who had attended classes with Tang Jianwei, and asked them carefully, but there was nothing new in the end The two women, Fan Xuan and Lu Xiuying, were most suspected.

After leaving, Rosen said: "I just said it's useless to come again. Except for Fan Xuan and Lu Xiuying, the relationship between the parents of other students and Tang Jianwei is very ordinary. As for Fan Xuan and Lu Xiuying, they are not at all. They don't have the time to commit crimes, and besides, they shouldn't do such stupid things because of emotional matters. Fan Xuan lives very clearly, and Lu Xiuying is even acting on occasion, as long as she likes to tease her, let alone He might kill for love."

Xiao Qiushui said: "Looks like we have to focus on Xiao Zhenqin's close friend."

Luo Sen said: "We have also had contact with her close friends. Didn't one of them say that Xiao Zhenqin would never bring Tang Jianwei with them when they got together, because she was worried that her close friends would snatch her away. No wonder Well, she herself is the one who pries into other people's corners, so she must take strict precautions when it comes to herself."

Xiao Qiushui didn't think so: "She may not bring it to a big party, but I don't believe that none of her close friends have met Tang Jianwei. Everyone has one or two people who he thinks he can absolutely trust and not defend himself against." Human. It is often such a person who can betray 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 tell you when she taught you before? For a person like Xiao Zhenqin who has received a Western-style education, she is different from many people in getting along with others. For example, many of us put our heart into making friends from the very beginning. Buddies, brothers, treat others as our own with all our heart and soul. Then in the process of getting in touch, we will gradually discover that this person does not really regard you as a buddy. , when you are brothers, gradually, you will drift away. But people like Xiao Zhenqin are different. At the beginning, they are cautious and wary of people they associate with, and they are skeptical at first. More or less there will be a certain purpose, and then slowly discover whether the other party is really worth dating or even paying for in the process of communication. The former type of people is from affirmation to doubt, and the latter type of people is from doubt to affirmation The latter kind of person is terrible, once he is sure that person is worthy of his trust, then he will firmly believe in it."

Luo Sen nodded. He remembered that Shen Chen had indeed mentioned this point during a business training session. At that time, he talked about the cultural differences between the East and the West and the impact of Westernized education on psychology.There was no such training in the team before, only after Shen Chen came.

But the colleagues in the team really like Shen Shen's training method, at least it is not boring, and he can combine it with many practical cases.To put it bluntly, the training Shen Shen did was just an extension of criminal psychology.

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

Xu Jing was very cooperative. The first time she received Xiao Qiushui's call, she and Xiao Qiushui agreed 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, did you delay your work?" Xiao Qiushui greeted with a smile.

Xu Jing gave him a blank look: "If I said delay, would I disappear?"

Xiao Qiushui was a little embarrassed, and Luo Sen quickly helped him out: "We can't help it, you and Xiao Zhenqin are familiar, we just want to find out if Xiao Zhenqin has a friend who is very fun and even trusts?"

Xu Jing narrowed her eyes: "Could you be suspicious..."

Before Xu Jing could finish speaking, Rosen interrupted her: "Reporter Xu, you also know that we have our own discipline. Just because we're looking for you doesn't mean we suspect anything, it's just a routine inquiry."

"Tch, you're still playing with me." Xu Jing glared at Luo Sen with some dissatisfaction, and Luo Sen couldn't say anything more, just smiled.

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

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

It seems that it really matches Wang Lu's profile, sportsman!

Xu Jing saw their expressions in her eyes: "What do you mean?"

Xiao Qiushui said: "No, it's nothing, if you think about it carefully, is there anything else?"

"It's gone. If I have to find another one, it's me. We should have nothing to say."

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

"Oh?"

"She and Tang Mei are old neighbors. They are in the same school for elementary school and junior high school, and Tang Mei has always taken care of her. In front of her, Tang Mei is simply a woman."
