"Do you have a huge amount of foreign debt?" Xu Lang asked.

Tan Wenrui shook his head without thinking about it and said, "No." ”

"Are you sure?"

"My grandparents are retired, my grandfather is the vice president of S University, and he is still a university professor, and now he still has the title of professor at S University, he has a generous pension every month, and so does my grandmother."

"Where's your dad Tan Shihao?"

"My dad has a stable job, he doesn't have any bad hobbies, he doesn't smoke, he doesn't drink, he doesn't play cards and gamble, and he basically doesn't have any other hobbies except for reading and buying books."

"What about your mother Liu Yun? Does she have a huge foreign debt out there? Xu Lang asked.

Tan Wenrui shook her head again and said: "No, my mother is a very frugal person, in addition to buying me and my sister a few new clothes every year, she herself is reluctant to buy new clothes, let alone cosmetics, of course, it's not that she can't afford it, but she doesn't feel the need to buy these, she has always believed that people who are teachers are all teachers, and no makeup is the best, if the teachers are all makeup to class, it will have a bad impact on the students below." ”

Hearing Tan Wenrui say this, Xu Lang nodded, he thought for a while and asked, "Then who in your family holds the financial power?" ”

"To each his own."

"Each managing its own money?" Xu Lang raised his eyebrows, feeling a little surprised.

Tan Wenrui seemed to know what Xu Lang wanted to ask, so he said: "In our family, we have always been very democratic, except for the big things that my grandfather has the final say, the rest of the small things are discussed separately." ”

Xu Lang thought about it, and suddenly remembered Tan Wenrui's house, so he asked: "When I went to your house, I found that your house seems to be very big, what's going on?" ”

"Oh, you said the house, the house was assigned to him by the school when my grandfather was a teacher at S University, and he has lived there for more than 40 years." Tan Wenrui said.

"Your house seems to be a two-house layout, right?"

"Yes, when you go to our house, you should know that there are only 601 and 603 on the right side of our sixth floor, and there is no 602."

Xu Lang nodded, he only asked Tan Wenrui when he thought of this.

"Our family wasn't that big before, and later, after my parents got married, they were going to move out, but my grandfather tried his best to stop them and strongly opposed them moving out, so they discussed it and bought 602 next door, and then - did a major renovation and changed the two houses into one house, which is what you saw before."

After listening to Tan Wenrui's explanation, Xu Lang suddenly realized that when he entered Tan Wenrui's house, he felt that the house was too big, with five bedrooms and two living rooms, two kitchens and three bathrooms, and a study, all of which were almost ready to catch up with a villa. ”

"My grandfather's salary was relatively high that year, plus, he often published papers in some magazines, and also had some extra income, plus my grandmother's salary and my parents' salary, it was nothing to buy a house, originally, when my parents got married, they planned to go outside to buy a house, besides, our family's community is an old community, and the house is not so valuable, so it is still very cheap when I bought it, and it didn't cost much." Tan Wenrui said.

Indeed, Fenghua Community is an old community, this point, Ning Yanran had already told Xu Lang before, Xu Lang had also been to Fenghua Community, and knew that the houses there were indeed a little old, a family of six, four people made money, and supported two children, which was more than enough, and there should be no financial difficulties, it seems that it is not a murder because of money, thinking of this, Xu Lang looked at Tan Wenrui, hesitated again and again, and still asked: "Your father, that is, Tan Shihao, is having an affair?" ”

As soon as Xu Lang said this, the three people who sat down looked at Xu Lang with a look of surprise and shock, and Ning Yanran was the first to think of what Xu Lang meant by asking.

At the scene of the 603 murder, the doors and windows were intact, and there were no traces of prying and fighting, which ruled out the possibility of burglary, and Tan Wenrui's family had stable economic resources, considerable income, and no foreign debts, which ruled out the possibility of killing people for money, since it was not for money, then the tragedy was probably for love, especially the hostess Liu Yun suffered inhuman torture and abuse before her death, which was very much like the murderer's act of venting his anger, and he hated a woman so much, except for love, Xu Lang couldn't think of anything else for the time being.

"Consultant Xu, I respect you as a criminal investigation consultant, but please also respect the deceased, who is Professor Tan Boheng, you go outside to inquire, how could his son do such an immoral thing?" Ruan Fanghua said emotionally again.

Xu Lang ignored the excited Ruan Fanghua, just looked at Tan Wenrui quietly, trying to get the answer from him, after all, he was Tan Shihao's son.

Tan Wenrui is a very smart child, it can be seen from his participation in the math competition on behalf of their class, so, after experiencing the initial anger, he quickly calmed down, he pulled Ruan Fanghua's sleeve, signaling her not to be so excited, and then, he looked at Xu Lang, shook his head, and said with a serious and serious expression: "No, my father has always had a good reputation in school, and his relationship with his female colleagues is also very clear. ”

"And what about the students that your father brought with him? They are all children about your age, and they are at the age when love first blossoms. Xu Lang still asked aggressively.

Tan Wenrui didn't shake his head to deny anything, but nodded, and said: "The situation you said exists and exists, I don't deny it, it is true that some teachers have no professional ethics and will do such things, but I believe that my father will not do this, if he really has any improper relationship with a student, the teachers and leaders of the school will definitely know about it and give him punishment, and my father will not be rated as an excellent teacher every year." ”

In fact, although Xu Lang's question just now was very practical, it was also very excessive, if Xu Lang was asking Tan Shihao's colleague or leader to ask about it, it would naturally be understandable, but asking this question in front of his son made Xu Lang a little unkind and excessive, which made Ning Yanran feel that Xu Lang had changed again, and Xu Lang himself didn't seem to notice.

After Xu Lang listened to Tan Wenrui's story, he pondered for a moment, and then asked, "Do you have any other relatives in your family?" ”

"There are no direct relatives, but there are a few distant relatives, but they don't have much contact, except for walking around each other during the New Year, they basically don't have much contact."

"What do you distant relatives do? Have you ever borrowed money from your family? ”

Tan Wenrui shook his head and said, "How can you borrow money if you don't have much contact, as for what they do, I don't know very well, I don't know much about them." ”

"And how is the relationship between your family and the neighbors?" Xu Lang asked.

Tan Wenrui thought for a while and said; "Everyone lives in a community, and when we look down and don't see anyone who looks up, we naturally know each other, and we get along well."

"And what's your next-door neighbor's name?" Xu Lang asked.

"You're asking about the residents of 601?" Tan Wenrui asked.

Xu Lang nodded.

"His name is Mao Dehui, and he is a self-employed person who pours seafood, what's wrong with him?" Tan Wenrui looked at Xu Lang and asked puzzled.

Xu Lang frowned, and asked with some puzzlement: "Isn't Fenghua Community a school district house assigned by the school?" Aren't all teachers living there? How can there still be self-employed? ”

Hearing Xu Lang ask, Ning Yanran, who was in charge of recording, put down the pen in her hand and explained: "Although the Fenghua community is a school district house, it was a long time ago, and now the school has long been divided into houses, and those teachers who have been assigned to the house, their children have also grown up, married and had children, the teacher's children are not necessarily teachers, they may also do other professions, after they grow up, they have money in their hands, so they go outside to buy a new house, since they have a new house, then the old house will naturally be sold, Someone sells it, and someone buys it, and after a long time, the residents living in Fenghua Community are not necessarily teachers. ”

Hearing this, Xu Lang suddenly realized, he looked at Tan Wenrui and asked, "How is the relationship between Mao Dehui and you?" ”

"He's not bad, he often comes to our house, and every time he comes, he doesn't come empty-handed, and he often brings some seafood."

"It seems that the relationship between your two families is good." Xu Lang said.

"He did it mainly for his son." Tan Wenrui said.

"Oh, what's going on?" Xu Lang asked curiously.

It turns out that Mao Dehui is Chinese New Year's Eve eight years old today, not from the urban area of S City, but from the countryside near S City, as for which village it is, Tan Wenrui doesn't know, he grew up by the sea since he was a child, so he is very knowledgeable about seafood, after he entered the society, he has been engaged in seafood wholesale, the business is not big, but it is not bad, later, married a daughter-in-law, gave birth to a child, the child is fifteen years old this year, just went to high school, Mao Dehui got married a few years ago, divorced, because Mao Dehui is engaged in seafood wholesale, always driving away from home, His daughter-in-law is at home alone, and she has to take care of the business in the store, and she has to take care of the children, and she has to go to her hometown every once in a while to see Mao Dehui's old mother, after a long time, Mao Dehui's daughter-in-law can't stand it, so she filed for divorce, and finally, Mao Dehui gave the woman more than half of the property, and then lived alone with the child.

Two years ago, Mao Dehui's mother also passed away, Mao Dehui lived alone with the child, the child was admitted to high school, Mao Dehui was very happy, but the fifteen or sixteen-year-old child is the period of youth rebellion, since the child was admitted to high school, the academic performance has been declining, so Mao Dehui often goes to Tan Wenrui's house, after all, Tan Wenrui's family is a teacher, and they can help make up for the child's class, so the two families have frequent contacts.

After listening to Tan Wenrui's story, Xu Lang was silent for a long time before he said, "So that's the case." ”

"Officer Xu, what's wrong with Uncle Mao? Does my family's murder have anything to do with him? Tan Wenrui asked tentatively.

Xu Lang looked at Tan Wenrui's immature cheeks, shook his head with a slight smile, and said, "It's nothing, your Uncle Mao was the first to arrive at the scene, and he is also the person who reported the crime, according to our regulations, I just asked you about his situation." ”

"Oh."

Hearing Xu Lang say this, Tan Wenrui relaxed and didn't think much about it.

Xu Lang turned his head, looked at Ning Yanran and asked, "Do you have anything else to ask?" ”

Ning Yanran was stunned for a moment, then shook her head and said, "No." ”

"Then let them sign and go back first." Xu Lang said.

Ning Yanran nodded.

After Tan Wenrui signed the interrogation transcript handed to him by Ning Yanran, he looked at Xu Lang and Ning Yanran and said, "Whether my family's body is here with you, I want to take a look." ”

Hearing Tan Wenrui's request, Ning Yanran was stunned for a moment, and then, she turned her head to look at Xu Lang, with an inquiring look.

Xu Lang hesitated slightly, nodded, and said, "Okay, but there is one thing I want to explain to you." ”

"What's the matter? You say. ”

"Since you are a family member of the victim, in a murder like this, according to the regulations, we are going to perform an autopsy, you see," Xu Lang said.

"I know, as long as you can catch the murderer of my whole family as soon as possible, if you want to dissect it, you can do it."

After all, Tan Wenrui is a highly educated college student (there was a mistake in what was written before, Tan Wenrui is nineteen years old, not a high school student, but a college student, a clerical error, correct it again.) He knew that the autopsy was to find the real cause of death of his family, if it was the older generation, he would definitely try his best to stop it when he heard that the autopsy was going to be performed, but Tan Wenrui was not, he was very open-minded and did not embarrass Xu Lang and them, of course, even if Tan Wenrui did not agree to the autopsy, as long as the case was solved, the autopsy could still be compulsory, but doing so would definitely have a great impact on the psychology of the victim's family, so Xu Lang would tell Tan Wenrui about it.

After saying these things, Ning Yanran took Ruan Fanghua and Tan Wenrui to the dissection room, while Xu Lang stayed alone in the second criminal investigation team.

Xu Lang sat on the swivel chair, his body lazily nestled in the chair, one hand touching his chin, one hand on the table, his fingers gently tapping on the table, frowning, thinking about things.

Judging from the contact and conversation between Xu Lang and Tan Wenrui just now, Tan Wenrui should have no motive for committing the crime, as for whether there is time to commit the crime, since Tan Wenrui mentioned his roommate and other people, Xu Lang believes that Ning Yanran will definitely go to his school to investigate according to Tan Wenrui's confession, as far as it is concerned, Tan Wenrui is not suspected of committing a crime, Xu Lang's previous speculation has been self-defeating, although this is not very good news for solving the case, but for Xu Lang and Ning Yanran, it is a good thing, after all, No one wants to see a smart and high-achieving student like Tan Wenrui embark on the road of breaking the law and committing crimes.

The occurrence of ordinary homicides is nothing more than three types, premeditated murder, murder of passion, and indiscriminate homicide.

There are many inducements for premeditated murder, which may cause hatred, or it may be for money, or it may be caused by the accumulation of contradictions such as quarrels, and passion murder is caused by overreaction when people are emotional, and general passion homicide is divided into impulse homicide and manslaughter. A murderer with an anti-human-human personality is either a psychopath.

Judging from the murder of Tan Boheng's family, Xu Lang believes that this is a typical premeditated murder, which can be seen from the death of Tan Boheng's family of five, first poisoning, then killing people with local materials, and finally torture, as for killing for vendetta, or love killing, or killing for money, or killing for other reasons, Xu Lang does not know for the time being, and there are no clues and evidence to give Xu Lang a direction.

Premeditated murder is divided into acquaintances and non-acquaintances, in this case, Xu Lang feels that it should be the former, from the location of the death of Tan Boheng's family of five, it can be seen that the murderer knows the situation of Tan Boheng's family very well, and is very familiar with Tan Boheng's family, otherwise, Tan Boheng and Tan Shihao would not have been poisoned to death, and Fan Ziyao would not have been killed on the sofa in the living room, and Liu Yun would not have been killed in the kitchen in home clothes.

Before seeing Tan Wenrui, Xu Lang guessed that it should be a vendetta or a love killing, the reason why Xu Lang thought it was a vendetta was because the murderer didn't even let go of the seven-year-old girl, from this point of view, the murderer came to destroy the door, but, judging from the conversation with Tan Wenrui just now, Tan Boheng's family and people don't have any big grudges, just like Tan Wenrui himself said, the five people who were killed, except for the seven-year-old girl Tan Jingjing, the remaining four people are teachers, And Tan Boheng and Fan Ziyao have both retired.

People who are teachers are not the same as people who work in society, the main responsibility of teachers is to teach and educate people, they are mainly facing students, Tan Boheng and Fan Ziyao are university teachers, Tan Shihao and Liu Yun are high school teachers, Tan Boheng and his wife have retired, university teachers are still very loose in the management of students, firstly, there are many students in the university, there are dozens or hundreds of people in a class, and the teacher cannot manage every student, secondly, college students in college, as long as they do not skip too much class, Don't fail too many subjects, teachers generally don't care much about them, therefore, university teachers are still relatively relaxed, and high school teachers are a lot more tired, after all, every year there are students in the third year of high school to take the college entrance examination, and high school teachers are under a lot of pressure, and the requirements for students are naturally stricter.

In this way, the possibility of vendetta is very small, but if it is not a vendetta, then how can those scars on Liu Yun's body be explained? How to explain the death of the little girl Tan Jingjing? Xu Lang couldn't figure it out.
