Is it the lack of education? Or is it moral decay?

Meng Lanfeng was forty-five years old at the time, divorced and single, her parents had died, her only relative had only one son, named Meng Chengcai, nineteen years old, was in her sophomore year, Meng Lanfeng married her boyfriend not long after graduating from college, not long after getting married, Meng Lanfeng found out that her boyfriend was cheating, so the two divorced not long after they got married, and after the divorce of the two people, Meng Lanfeng found out that she was pregnant, and her family and friends persuaded her to kill the child, But the kind-hearted Meng Lanfeng did not follow these suggestions to beat the eldest child, but chose to give birth to the child, and gave the child a successful name, perhaps, this is the greatest expectation of a mother for her son.

Meng Lanfeng has not remarried after the divorce, raising Meng Chengcai alone to grow up, Meng Lanfeng is teaching in high school, it is very hard to raise children at the same time, when the people around her persuade her to find another man to marry, she always excuses herself and says that the child is still young, she does not want to get married for the time being, but when Meng Chengcai gradually grows up, relatives and friends persuade her to find one, she excused herself and said that the child is now growing up and cannot bring psychological pressure to the child, just like that, Whenever someone persuaded her to remarry, when she introduced her to someone, she politely declined, and until she was killed, Meng Lanfeng had been single all these years.

The time of the case was in mid-July at that time, that is, not long after the summer vacation had just begun, the students were on vacation, and as a teacher, she also left the school and returned to her home, Meng Lanfeng is a very responsible teacher, she taught in high school for more than ten years, every summer or winter vacation, she would give some poor students in her class and ask them to come to her home to make up the class, of course, Meng Lanfeng's make-up class is not the kind of paid make-up class that people imagine, but free make-up class, She did this to help these poor students improve their academic performance, so that they can be admitted to a good university in the future, and have an explanation for the students themselves and their parents.

Although Wu Yong was not a bad student back then, in the three years he was in high school, except for most of the school time, he spent most of his time at Meng Lanfeng's house, and Meng Lanfeng treated Wu Yong like his own children, and even treated them better than Meng Chengcai, so when the news of Meng Lanfeng's murder was spread, many students who Meng Lanfeng had brought out spoke out, hoping that the police would solve the case as soon as possible and catch the murderer of their teacher.

The police also launched an intensive investigation work non-stop.

First of all, the autopsy results on the forensic doctor's side came out, the deceased probably died three days before the body was found, and the cause of death was the same as that investigated at the crime scene, it was cardiac arrest caused by a sharp weapon piercing the heart, and died of excessive blood loss.

After the autopsy results were obtained and the time of death was determined, the police launched a detailed investigation around the period before and after Meng Lanfeng's death.

Because the community where Meng Lanfeng lives is an old community, the monitoring facilities are not perfect, and it is basically impossible for the police to find the murderer through the monitoring probe, so the police first questioned Meng Lanfeng's neighbors, during the questioning, according to the memories of the neighbors, a few days before the crime, they saw several children dressed as students, who came to Meng Lanfeng's house one after another, and they stayed at Meng Lanfeng's house for about a week, and then left together, and the time they left was the day before Meng Lanfeng's death.

In addition, according to Meng Lanfeng's upstairs neighbors, on the day of Meng Lanfeng's death, when she went home from grocery shopping, when she passed in front of Meng Lanfeng's house, she seemed to hear the sound of Meng Lanfeng arguing with someone, but Meng Lanfeng's voice was relatively small, and she didn't hear what she was arguing about, because Meng Lanfeng was a teacher, it was normal to speak louder, she thought that Meng Lanfeng was angry with the students who came to the house to make up the class, so she didn't care much at the time.

And according to the memories of the neighbors who lived downstairs Meng Lanfeng, on the day of Meng Lanfeng's death, he once heard the sound of clanging from upstairs, as if he was chopping something, at first, he thought that Meng Lanfeng was chopping ribs at home, he didn't care much, but, the sound lasted for more than two hours, he was a little annoyed by the noise, so he stood on his balcony and shouted at the top, after he finished shouting, the sound of the clanging bell upstairs disappeared, but, according to his story, At that time, there was no response from Meng Lanfeng upstairs, he was a little annoyed at the time, he didn't think much about it when he heard that the voice was gone, and now that he thinks about it, the voice he heard at that time should be the voice made by the murderer when he was dismembering Meng Lanfeng's body.

The reason why the police still saw the undismembered torso at the scene should be because the neighbor shouted and frightened the murderer, so the murderer had to stop dismembering the body and then fled the scene with the dismembered body parts.

It was the two students brought by Meng Lanfeng who called the police, and the reason why they came to Meng Lanfeng's house was mainly because Meng Lanfeng asked them to come over with the homework she assigned three days later to make up for the class, but after they arrived at Meng Lanfeng's house, they knocked on the door for a long time, but Meng Lanfeng didn't come to open the door, they thought Meng Lanfeng was going out at first, so they went downstairs to have a meal, and returned to Meng Lanfeng's door, and continued to knock on the door, knocked for a long time, but still no one came to open the door, Just when they were about to leave and go home, one of the students found blood stains at the door, so he came to the door and took a closer look, and found that it was indeed bloodstains, and he also smelled a faint smell of blood and meat, he immediately felt wrong, so he went downstairs to find the property to come up and take a look, after the property came up, he found that there were indeed blood stains at the door of Meng Lanfeng's house, and the property also felt that there might be an accident at Meng Lanfeng's house, so he took the key and opened Meng Lanfeng's door. After entering the door, they saw a terrifying scene, and they were frightened at the time, and when they finally recovered, they thought of calling the police.

During this period, the other people in the community also noticed that something was wrong here, and they all came to see the excitement, and they saw the horrible scene, at that time, many people entered the room and left footprints in the room, but they only stayed at the door and in the living room, and did not enter the rest of the room, although they destroyed the scene to a certain extent, however, they did not completely destroy the scene.

After the police investigated here, they came to the following conclusions.

First, when the neighbor passed by the door of Meng Lanfeng's house, it was around 11 o'clock at noon on the day of the crime, and the jingling sound heard by the downstairs neighbor was around 2 o'clock in the afternoon, and the time of death given by the forensic doctor was that the deceased was between 12 o'clock at noon and 5 o'clock in the evening three days before the body was found, the reason why the forensic doctor gave this time period was mainly because they found an incomplete lunch in the stomach of the deceased. Especially when it comes to eating, she eats on time, usually Meng Lanfeng eats at about twelve o'clock at noon, according to this information, it can be concluded that the time of Meng Lanfeng's death is probably after lunch, that is, between twelve o'clock at noon and two o'clock in the afternoon.

Second, Meng Lanfeng has been single for many years and has not remarried, and there are many people who pursue her, but she politely refused, and there is no intimate relationship with a certain opposite sex, she gets along with everyone of the opposite sex as friends or colleagues, even if those who have pursued her are still friends and colleagues with each other after being rejected by her, so the police temporarily ruled out the possibility of love killing.

Third, Meng Lanfeng is kind and sincere, and there is no big contradiction with someone, if there is, it is her ex-husband, but, according to the police investigation, Meng Lanfeng's ex-husband left S City after divorcing Meng Lanfeng, went to other places, and it didn't take long for him to get married, for so many years, this man has not returned to S City, and Meng Lanfeng's ex-husband has not returned to S City, and neither of them has ever met Meng Lanfeng again, Meng Lanfeng's ex-husband didn't know that Meng Lanfeng gave birth to a son to him, plus, at the time of the crime, Meng Lanfeng's ex-husband's family had no time to commit the crime, and they all had a complete alibi, so their suspicion was also ruled out, in addition, no one has any big contradictions with Meng Lanfeng, if there is, it is the students Meng Lanfeng once led, although some students have hatred and resentment towards the teacher because they have been criticized by the teacher, so they have murderous intentions and commit crimes. It happens occasionally all over the world, but no student like Meng Lanfeng should do this, of course, this point needs further investigation to know, so the possibility of killing people due to vendetta is not certain for the time being, but this probability is very low.

In ordinary homicide cases, the motive for committing the crime is nothing more than killing people for revenge, killing people for love, killing people for money, and killing people with passion.

The point of killing people because of love can be basically ruled out, firstly, Meng Lanfeng's life style is very decent, and secondly, her age is not young, she is already in her forties, of course, people in their forties are not new to get married in the 21st century, but after the police investigation, no signs of this were found.

Because of the murder of money, after the police investigated the scene, and after the forensic doctor conducted an autopsy on the body of the deceased, it was excluded, the property of the deceased's family was not missing, Meng Lanfeng's wallet, bank, and passbook were all at home, and there were nearly 1,000 yuan in the wallet, which was the money she was going to give her son Meng Youcai's tuition fee for the next semester, and some of her gold and silver jewelry were placed in the bedroom, if someone killed someone because of money, they would definitely find these things, and take them away, but they didn't take them away, as for the murder because of sex, According to the forensic autopsy, it was found that the deceased had no traces of sexual relations with people before or after death, and the possibility of killing people for wealth was also ruled out.

As for the vendetta killing, although this point is not certain for the time being, it is very unlikely, and if you want to determine whether there is such a possibility, as long as the police continue to investigate.

Ruled out the first three possibilities, the police focused on the possibility of murder by passion, murder by passion and the motive of the first three killings are completely different, the aforementioned murder due to hatred, affection, and wealth all have a clear purpose, however, passion killings are temporary, and the motive may be caused by an accidental factor, it may be an unintentional word, it may be because of something, or a verbal conflict, if you want to determine whether it is a murder of passion, you must investigate clearly, Meng Lanfeng had a quarrel with someone before he died, as long as this person is found, then the case will become much clearer.

So, the police focused their investigation on the person who had a quarrel with Meng Lanfeng, and the first thing the police suspected was the high school students who Meng Lanfeng's neighbors saw before who came to make up the class, and the police summoned several high school students who went to Meng Lanfeng's house to make up the class to the Public Security Bureau for questioning and investigation, of course, their parents were on the side in the process.

At that time, there were a total of seven people who went to Meng Lanfeng's house to make up classes, and their academic performance was the worst in the class, so Meng Lanfeng would use the summer vacation time to make up classes for them, and the parents of these students knew about the make-up classes, and the parents of these students were very grateful to Meng Lanfeng when they learned that Meng Lanfeng was going to make up classes for their children, and they all said that Meng Lanfeng was a good teacher, and they didn't believe that Meng Lanfeng was killed because he offended someone. Naturally, he didn't believe that his child would be the murderer of Meng Lanfeng.

However, after a detailed questioning by the police, these seven children, including the two students who found Meng Lanfeng's body, did not have the time and motive to commit the crime, on the day Meng Lanfeng was killed, they all had an alibi, and not one or two people could prove it, their friends and classmates could prove it, so the seven students who were most suspected were ruled out one by one, which made the police investigation deadlocked.

Time passed bit by bit, the time to solve the case was getting closer and closer, the public opinion in the society was getting bigger and bigger, and the pressure on the police was getting bigger and bigger.

He told the police that he had seen Meng Lanfeng and her son Meng Youcai quarrel at school, it was a weekend, most of the students went home, and he happened not to choose to go back, and he accidentally saw that Meng Youcai came to the school to find Meng Lanfeng, at first the two of them talked very well, and later, as if because of something, Meng Lanfeng suddenly got angry and reprimanded Meng Youcai a few words, Meng Youcai kept his head down at the time, didn't say anything, and finally left alone, It was also the first time he saw Meng Lanfeng actually have such a stern side, which had a great impact on his previous impression of Meng Lanfeng, but after he found out about it, he didn't think much about it, let alone mention it to other classmates, after all, Meng Lanfeng was very gentle and tolerant when he treated them, even if he said it, other classmates couldn't believe it, so at first, when the police questioned him, he didn't say it, and when the police began to suspect that they killed Teacher Meng Lanfeng, That's when he said it.

The police didn't believe that it would be Meng Youcai who killed Meng Lanfeng at first, at least Wu Yong didn't believe it, because his relationship with Meng Lanfeng was also a teacher and friend, he had known Meng Youcai for a long time, in Wu Yong's impression, Meng Youcai was a taciturn child, and he listened to Meng Lanfeng's words very much.

Meng Youcai has studied very well since he was a child, and is the first holder in the class, the reason why Meng Youcai has good academic performance is mainly because of Meng Lanfeng, after all, she is a high school teacher, and the teacher's responsibility is to educate students and impart knowledge to students, and Meng Youcai has been under the influence of his mother who has been a teacher since he was a child, and it is normal for him to have good grades, and if his grades are not good, it is not normal.

As for Meng Youcai's obedience, Wu Yong felt very deeply, because when he went to Meng Lanfeng's house to make up the class, he saw that when Meng Lanfeng was giving Wu Yong and them a make-up class, Meng Youcai was studying on the side, and Meng Youcai was only in junior high school at that time, he and Wu Yong took classes together, learning the knowledge of the third year of high school, and they didn't feel difficult at all, after the make-up class was completed, Meng Lanfeng would stay at home to eat, and Meng Youcai At this time, he would help Meng Lanfeng cook and do housework together, after eatingHe would consciously tidy up the dining table and kitchen, and then go back to his room to continue studying.

In Wu Yong's impression, he never seemed to see Meng Youcai idle, Meng Youcai either followed them to make up for classes, or stayed in the room alone to study, and almost never went out to play, even if he wanted to go out, he would tell Meng Lanfeng in advance and ask for permission before going out.

In addition, Meng Youcai is still a very polite child, every student who goes to his house to make up for class, Meng Youcai will politely call his brothers and sisters, and then pour water for them to make tea, however, Meng Youcai has very few words, almost does not speak much, when Wu Yong is there, he feels that Meng Youcai, who is only twelve or thirteen years old, is like a seventeen or eighteen-year-old child.

Taciturn, polite and sensible, obedient and studious, this is Wu Yong's biggest impression of Meng Youcai, so he doesn't believe that such an honest child will be related to his mother's tragic death, however, Wu Yong doesn't believe it or not, what should be investigated is still to be investigated, as the saying goes, real gold is not afraid of fire, if he is really fine, he is not afraid of investigation.
