Dust Archives Part 226: Dust under the skylight

Abnormal Human Encyclopedia: The case of decades ago, everyone should read the story

In the spring of 1952, a case of collective poisoning of kindergarten children occurred in Tianjin. The public security organs conducted a meticulous investigation around "who is the poisoner", cleared through the fog, eliminated several difficulties, and finally locked the criminal suspect...

1. Drug cases are sudden

Thursday, April 3, 1952.

This is a gangster day in Mingfeng Private Kindergarten, on this day, there was a poisoning case in the kindergarten, and all the young children in the kindergarten were poisoned!

Mingfeng Kindergarten was invested and operated by Xie Xiangyi, who settled in Huijinmen, England in the year of the victory of the War of Resistance Against Japanese Aggression, and served as the director of the kindergarten, and was divided into three levels: small class, middle class and large class. At the time of this case, there were 67 young children aged 3 to 6 in the kindergarten.

Xie Xiangyi personally manages Mingfeng Kindergarten as the director of the kindergarten, and his ideas are quite british. For example, kindergartens serve two meals and two snacks a day from Monday to Saturday. All the meals and snacks are cooked and prepared by professional chefs she has hired. Not only do chefs have to make dim sum, but every Thursday they also give young children a dim sum making class: take the ingredients to the classroom, explain how to make them for the middle and older children, and let each child make a dim sum. Every time he came to this class, No matter how busy Xie Xiangyi was, he would definitely come to the scene to make snacks with the young children.

Young children are most enthusiastic about the dim sum making class, and in their consciousness, after washing their small hands, they take a lump of flour and knead it into a shape according to their imagination, and when the chef takes it to the kitchen and sends it back, it becomes a delicious snack, which is far more interesting than playing with plasticine.

This morning, the kindergarten held a dim sum class as usual. Xie Xiangyi was not present because she was going to attend a meeting at the Education Department of the district government, and xiao lu, a nurseryman, took her place and another childcare worker, Xiao Gu, to assist chef Xu Derong in this class. On this day, Xu Derong taught the young children to make twist flowers. Each person was given a small piece of haired dough and asked the children to follow his example and knead it. After it is made, Xu Derong also has to check and judge one by one, of course, mostly to give praise and encouragement, and then use a tray to collect the children's works and send them to the kitchen to fry.

In retrospect, this poisoning case was a precursor, but it did not attract attention. The warning was given by a four-year-old girl who, when the nursery worker Xiao Lu, was carrying a tray to collect her work, she once said: "This dough has a strange smell." Xiao Lu heard it, and lifted the tray up to smell it, but there was nothing to feel.

It seems that the child's sense of smell is more sensitive than that of adults, and the feeling of this four-year-old is accurate, but unfortunately it has not attracted the attention of the nursery staff. The warning message issued by the four-year-old was quickly confirmed: in a few moments, Xu Derong fried the twist flowers and distributed them to the young children by the nursery staff of each class. Tianjin's twist flower world is famous, and Xu Derong had been an apprentice in Tianjin's most prestigious eighteenth street "Gui Faxiang" when he was young, although he did not learn the core skills of making Jinmen's "Gui Fa xiang eighteenth street twist flower", but it was certainly very popular in this small kindergarten. The twist flowers he fried are sweet and crispy, suitable for all ages. At the moment, the young child chewed with the twisted flowers distributed, and the four-year-old girl who had issued the warning had forgotten that she had said that "the dough has a strange smell", and like other friends, she quickly ate a small twist flower.

Poisoning begins to occur after about a quarter of an hour. First, about five young children said "uncomfortable" at the same time, and then more than a dozen young children, including these five, began to vomit and called "stomachache". Down, there was a full outbreak, and within a few minutes, all the young children in each class were in abdominal pain, vomiting, and crying. The nurseryman was suddenly startled and scrambled, and two of them couldn't help but cry. Chef Xu Derong and Mama Liu, who helped the cook, rushed to hear the news, and when they saw the situation, they also had no opinion.

In the midst of the panic, Director Xie Xiangyi returned. She is a person who has seen the world, and immediately arranged for the nursery staff to contact the vehicle to send all the young children to the hospital for treatment, and then she called the fourth branch of the Tianjin Municipal Public Security Bureau and the guanduan police station in the kindergarten area.

The Fourth Substation received a call, and at the moment, five police officers led by Deputy Director Li Yiyan rushed to the kindergarten. When Li Yiyan and his men arrived, the police station had already dispatched all the people to seal off the kindergarten. In fact, only the kindergarten is cooks Xu Derong and Mama Liu at the moment, and Xie Xiangyi and all the nursery staff are escorting the sick children to several hospitals with the car. Li Yiyan simply asked about the situation, and immediately called the hospital to understand the treatment situation. The answers of several hospitals are consistent: from the symptoms, these young children are food poisoning, what the poison they eat is not clear, the drug is violent, but the dose may not be large, sent to the hospital in time, so the sick child seems to be life-threatening, but whether there are sequelae is not yet easy to draw conclusions.

The case was quickly reported to the Municipal Public Security Bureau, and reported to the Municipal Party Committee and Municipal Government, and the leaders immediately instructed the Municipal Bureau and the Sub-Bureau to set up a special investigation team to solve the case as quickly as possible, arrest the criminal, and bring it to justice!

2. Investigate suspects

The joint special investigation team was composed of 10 criminal police officers from the municipal bureau, substation and police station, which was a relatively large special case team when the police force was very tight at that time. Li Yiyan, deputy director of the Fourth Sub-Bureau, and Meng Guang, head of the major case team of the Criminal Investigation Department of the Municipal Bureau, served as the head and deputy leader of the group, respectively.

The task force immediately put into operation: instructing the forensic doctors who came to the rescue to extract vomit and all the food ingredients in the kindergarten kitchen for testing; inspecting the scene; Xu Derong and Liu Mama, who remained in the kindergarten, to understand the situation of the case; sending staff to the four hospitals where the poisoned children were treated to talk with the nurseryman and the kindergarten director Xie Xiangyi one by one to understand the situation.

When the investigator talked to Xu Derong, he found that he covered his abdomen with his hands from time to time, and his face showed an uncomfortable look, so he asked him what was wrong? Xu Derong said that he also ate a twist flower, and now he feels a little pain in his stomach, and he is probably poisoned. It turned out that Xu Derong had also fried and fried the small twist flower he had demonstrated when he gave the children a dim sum making class. The investigator was about to take him to the hospital, and he shook his head and said no, because after discovering the accident, he immediately got some soapy water and drank it to induce vomiting.

By the afternoon, the situation of the poisoned children was clear: after hospital treatment, all the children were out of danger, most of the children had been taken home by their parents, and a small number of sick children were still under observation, but they could be discharged from the hospital on the same day.

Nurseryman Lu Reflected to the Investigator the "weird" situation that the four-year-old had told her. The investigator immediately went to the little girl who had been taken home by her parents, and asked about it, and the girl said that the strange smell she smelled was very similar to the smell of the medicine that her grandmother used to kill rats, but it was very light, and after it was fried, there was no smell at all.

The task force immediately thought that the poison that was thrown might be rat poison, and was about to contact the forensic doctor, who called: according to the results of the extracted vomit test, it was determined that the poison was zinc phosphide rat poison. After laboratory analysis of all the raw materials extracted for making twist flowers, it was determined that there was no residual poison in all the raw materials, so the poison was directly put into the dough used to make twist flowers. Judging from the ratio of the dose of the poison administered to the number of people expected to be poisoned, it is likely that the perpetrator's criminal motive was not to kill, but merely to vent his anger or to have an impact on it, which would lead to the desired consequences.

This conclusion of the forensic doctor is very enlightening for the next step of the investigation work of the task force: since the poison is cast in the dough, it is only necessary to know when and the noodles, when to make twists into the time period of frying, and then list all the people who have entered the kindergarten kitchen during this time period and have the conditions to poison, and the criminals must be among these personnel, and they can be found by investigation and screening one by one.

So I brought the chef Xu Derong to inquire about the twist flower making process. Although Xu Derong also ate poisonous twist flowers, but with the weight of adults, the poison ingredients in each twist flower were not even poisoned by young children, and he used the soil method to cure it himself, so he did not go to the hospital at this moment, and the abdominal pain was stopped. He told the investigators that to make twist flowers, it was necessary to mix the appropriate amount of old noodles and flour with water the first night, put them in a clay pot overnight to let the dough ferment, add rock sugar and other ingredients the next day, and finally pull it into shape and fry it out in the pan. Kindergarten children learn to make it, which is actually the last process before frying. What Director Xie said was not really to let the children learn the craft of making dim sum and make a living from it when they grew up, but to make them understand the basic principles of life through such labor.

So, is there someone on duty at night in the kindergarten?

Duty? I slept in kindergarten!

I asked the helper, Mama Liu, and learned that this morning she was the first kindergarten to arrive, and the second to arrive was Director Xie. Down to the third and fourth and beyond, the investigators did not ask, because the other nurserymen never entered the kitchen, which was the rule of Director Xie. Mama Liu's job is in the kitchen, basically staying busy in the kitchen all day; Xu Derong is not to mention; Xie Xiangyi's job is in the headroom, but she also has to go into the kitchen several times a day to check hygiene and check the quality of meals. On the same day, she also went to the kitchen at 7 o'clock as soon as she arrived at kindergarten. Later, before going to the district government meeting, I also went into the kitchen.

In this way, the special case team basically determined that the target of poisoning was among Xie, Xu, and Liu.

Mingfeng Kindergarten has such a big thing, not to mention the poisoned children also need to carry out physical and psychological recovery, that is, do not need to recover, it is impossible to continue the class immediately the next day, the district government has long been a paper stamped with a big red seal notice posted at the gate, did not say the reason, only said "for some reason to suspend classes, when to resume, waiting for the notification." In this way, the kindergarten became the site of the task force. The task force decided that Xiao Lu and eight other childcare workers and Luo Zengyi, assistant to the head of the kindergarten who did not come to work at the kindergarten that day, were on standby at home and were on call; Xie Xiangyi, Xu Derong, and Mama Liu stayed in the kindergarten to assist in the investigation - in fact, it was quarantine review.

The investigators talked to Xie, Xu, and Liu respectively, and then the special case team held a meeting to summarize the contents of the conversation and analyze and sort out accordingly.

The first suspect who thought that should be excluded was Xie Xiangyi, the director of the kindergarten, because it was untenable to speculate on her motives from any angle: the kindergarten did not purchase insurance (there was no such insurance to buy at that time), and when such accidents occurred, the loss was Xie Xiangyi's own, and although her family had money, there was really no need to spend the money on compensation she deliberately created, and she also had to bear the risk of being held criminally responsible; she did not have any holidays with the parents of all the children who entered the kindergarten. It is not possible to take revenge by committing the case. In addition, according to the investigation of Xu Derong and Liu Mama, although Xie Xiangyi entered the kitchen twice that morning, she did not approach the tile basin containing the dough, and there were two pairs of eyes next to her, even if she wanted to poison her, she had no chance.

After Xie Xiangyi was excluded, the task force began to analyze Mama Liu. Judging from the time and opportunity of the crime, she has a conditional hand. The kitchen is on her and Xu Derong, and although Xu Derong has her help as a cook, he still has to do a lot of work. When he was working, it was impossible to keep his eyes fixed on Mama Liu—there was no need to stare. However, Mama Liu also lacked the motive to commit the crime. She was a native of Sanhe County, widowed and widowed in the year of the victory of the War of Resistance, and her son died of illness the following year, and the clan thought that she was a "mourning star" and drove her out. She was forced to become a beggar, and when she was begging in Tianjin, she happened to meet Xie Xiangyi, who was running around to build a kindergarten. Xie Xiangyi bought a bun for Mama Liu, who was already too hungry to stand, and after learning about her situation after talking, she developed a sympathy, so she decided to take her in and work in the kindergarten that was about to open. In 1950, Xie Xiangyi again introduced a dock worker to Liu Mama and re-established a home, and the housing was provided by Xie Xiangyi. Therefore, Xie Xiangyi should be Liu Ma's benefactor, and Liu Ma has no reason to poison. Moreover, if such a big thing happens in kindergarten, it seems that there is no escape from closing the door, and when she closes the door, she is unemployed. Leave a good job and don't do it, but seek unemployment, the brain is in the water?

In this way, the doubts focused on the chef Xu Derong.

3. Report by letter

Compared with Xie Xiangyi and Liu Mama, Xu Derong's situation is just the opposite, his crime conditions and motives are mostly: bachelor, living in kindergarten, making twist dough is kneaded by hand, it can be said that from the beginning and the noodles to the fermentation of the dough cut into blanks and sent to the children, this long for more than ten hours he has the opportunity to start at any time, Liu Mama will not find out at all. Moreover, Xu Derong is an amphibious cooking technician who can both make dim sum and cook dishes, and when Xie Xiangyi first ran this kindergarten, it took a lot of effort to dig him up from the "Spring Breeze Proud Building", and his contract was signed for ten years. If Mingfeng Kindergarten was out of the door, he wouldn't have to worry about unemployment like Mama Liu did. Xu Derong also did not lack the motive for the crime: five days before the accident, he had vented in public for the fact that the accounts of the gang were unclear and was accused by Xie Xiangyi. Afterwards, he threatened Mama Liu and several nurserymen at least three times: What kind of spirit and what? Big deal everybody break up!

Break up? Is he talking casually or is he sincerely confiding? The task force decided to investigate.

The results of the investigation were: One of Xu Derong's brothers was recently preparing to open a restaurant and had already issued three invitations to Xu Derong to join. According to the brother told the investigator, because he offered a higher salary than kindergarten, and promised to give him dry stock, Xu Derong was willing to join. The third time he told Xu Derong about this, Xu Derong said that I wanted to jump to you, I didn't have a good time in kindergarten, my salary was not mentioned for many years, the head of the kindergarten was too strict with the kitchen, and he didn't let me drink, saying that I was afraid of affecting the children, and I already had the idea of leaving. However, things may not be easy to handle, because when Director Xie dug me from the "Spring Breeze Proud Building" to the kindergarten, he signed a ten-year contract with me, stipulating that I had to work in the kindergarten for ten years before I had the right to choose whether to leave or not. The clan brother said to ignore her, it was a pre-liberation contract, and he did not recognize it. If you don't believe me, you go and ask the lawyer. At noon last Monday, Xu Derong really went to ask the lawyer, it was the brother who accompanied him, the lawyer read the contract, said that from the content of the contract, the agreement between the two sides should be valid, because it does not involve politics, and what "exploitation, oppression" has nothing to do with it, the identity of the other party is also a law-abiding masses, so this contract is a purely civil contract, and its agreement can be extended to after liberation, you are not good to terminate.

Based on this, the special case team made an analysis and inference: Will Xu Derong because he cannot cancel the contract and climb another branch, thus creating a poisoning case and causing the kindergarten to close down and achieve the purpose of leaving naturally?

Therefore, the special case team decided to retain Xu Derong and conduct a special examination of him. However, Xu Derong, in the face of the investigators' interrogation, took a tough attitude and flatly denied that he was related to the poisoning case.

When the interrogation reached a stalemate, Li Yiyan, the head of the special case team, received a letter.

This is an anonymous whistleblower letter reporting that the poisoning case at Mingfeng Kindergarten was committed by a 22-year-old young girl. The girl's name was Xue Nali, and she was the biological daughter of Xie Xiangyi, the head of the kindergarten. The report letter said that at more than 8:00 a.m. on the day of the crime, Xue Nali had been to kindergarten! Going to kindergarten alone can not explain the problem, the report letter continues to break the news: Xue Nali and Xie Xiangyi, the mother-daughter marriage for the daughter has been in a fight, Xue Nali wants to break away from the mother-daughter relationship, for this reason, specially ran through the newspaper, the court, have not been accepted. To this end, she once pointed at her mother's nose and issued a threat, saying, "I want you to look good."

This whistleblower letter naturally attracted the attention of the special case team, and immediately decided to immediately conduct a peripheral secret investigation of this content.

Upon investigation, the following information was obtained -

Born in England, At the age of 15, She returned to China with her parents and settled down, attending a church-run nursing school in Tianjin. After graduating from nursing school in 1948, he entered the Yiyan Spinning Factory and worked in the factory's infirmary. The girl is cheerful and lively, simple and innocent, beautiful and foreign, and has a good family background, so she has been highly sought after when she was still nursing school, and the boys who stared behind her after stepping on the job were in rows. At that time, there was no such thing as "early love and early marriage", before liberation, it was possible to marry at any age, and in 1950, with the Marriage Law, you could legally marry at the age of 18. Therefore, Xue Nali also came into contact with several objects, but they all said goodbye to each other like dragonflies, until they met Pan Yao a year ago. Pan Yao, a college graduate and member of the underground regiment, did a period of political work after liberation, and was assigned to the Yiyan Spinning Factory last year to do trade union work. Xue Nali is the head of the union in the infirmary, and the two fell in love after more contact.

After Xie Xiangyi and his wife learned that their daughter had chosen Pan Yao, they met with the young man several times and asked someone to understand their family situation. Dissatisfied with the boy's family and unable to accept most of the elements of his personality, the couple, after consultation, voted against it. In this way, Xue Nali got into trouble with her parents, she was not Pan Yao, and she had to marry with the approval of her parents. Xie Xiangyi's husband is a university professor, a standard good gentleman, who can't stand his daughter's repeated bombardments and has to vote in favor. But Xie Xiangyi resolutely refused to give in, and for this reason, the mother and daughter quarreled several times and three times. Xue Nali knew that her mother had a good face, and in order to force her to give in, she even ran to the kindergarten to argue.

At about 8 o'clock in the morning of the crime, Xue Nali did go to the kindergarten, learned that her mother was in the kitchen, and went to the kitchen to look for it, but did not find it, and left. Judging from the time, Xie Xiangyi had already left the kitchen, went out through the back door of the kindergarten, and drove a private car to the district government to attend the meeting. So, was there anyone else in the kitchen at the time? Xu Derong drew water from the well outside the door, and Mama Liu was cutting vegetables on the kitchen side. After understanding it, I found that the position where Liu Mama was staying was exactly the same as the tile pot containing the dough. In other words, if Xue Nali was going to be poisoned, it would not have been discoverable at that time.

The special case team assigned investigators Xiao Huang and Xiao Zhang to go to the Yiyan Yarn Factory to investigate directly with Xue Nali. Xue Nali admitted that she had been to kindergarten that day, and that she had accepted her father's advice to improve her relationship with her mother and send movie tickets. The movie ticket was obtained by Pan Yao, because of an accident in the kindergarten, it could not be delivered to her mother, and she is still here. As for the reason why she should have gone to work that day and how she ran out in broad daylight, she was ordered to go to the district patriotic health committee to get a copy of the propaganda materials, and she happened to pass by the kindergarten, so she turned in by the way.

Xiao Huang and Xiao Zhang immediately investigated the director of the infirmary, Pan Yao, and Professor Xue, Xie Xiangyi's husband, and confirmed that Xue Nali's statement was not false. Pan Yao and Professor Xue also provided information that Xue Nali did not say: Last week, the three of them had a meal at a restaurant outside, specifically discussing how to do the work of Thanking Xiangyi to get them to approve of the marriage.

Based on the above investigation, the task force discussed and concluded that the basis for suspecting Xue Nali's crime was seriously insufficient -- that is, her suspicion of committing the crime could be preliminarily ruled out.

Fourth, the facts of the case are clear

In this way, a new question arises: Who wrote this whistleblower letter? Why did this man write this letter? How can you be so familiar with the situation? The task force felt that this situation deserved attention, because the letter writer might be related to the case!

At this time, the investigators lao Tang, Xiao Deng, and Xiao Ma, who had been arrested by Xu Derong, who had been detained in custody, suddenly made a new discovery. The interrogation of Xu Derong by these three people initially made a very bad deal, and Xu Derong's antagonism was serious, and he did not answer any questions at all except to deny that it had anything to do with the poisoning case. So the three of them changed their ways, chatting with Xu Derong about the case, the content outside the kindergarten, the south of the world, the north sea, the wide sky and the mountains. After talking like this for two days, I seemed to inadvertently pull the topic to the case, saying that we looked at you like a good person, and we should not be poisoned. Xu Derong said what is "like a good person", my surname Xu has always been a law-abiding good citizen, and he has pulled poisoning such a thousand knives to my head, that is really blind! Old Tang said that let's rip it up, someone has always done this, right? You didn't do it, Mama Liu didn't do it, and Director Xie didn't do it, so who threw the poison into the dough? Can you think about it, has anyone ever sneaked into the kitchen without you noticing?

Xu Derong really thought about it, thought about it all night. The next day, he told the investigator a content that had not been said before: On the morning of the crime, when he got up and went to the kitchen to start working, he found that there was dust on the stove, just at this time, Liu Mama came, he let Liu Mama wipe it off, and the two discussed whether there would be rats, which made Director Xie know that it was a big deal, and he had to pay attention to it. Originally, Mama Liu was going to buy a clip at noon to prepare to deal with rats, but she didn't expect an accident in the morning, so this matter was not mentioned. Now that he thinks back, he wonders if the skylight above the stove top is the skylight of the kitchen, and whether someone will climb in through the skylight at night and poison it?

The leader of the special case group heard the news and immediately instructed the three old Tang people to go to the kindergarten to investigate. When I asked Mama Liu, I confirmed that there was indeed such a thing. Then don't talk nonsense, find a ladder to go up to the skylight to see. At this glance, I caught sight of two footprints left on the skylight sill. In addition, traces of ropes were found on the wooden pole that connected indoor and outdoor wires on the roof of the skylight, and several clear fingerprints were found on the skylight glass. So, it was judged that someone had climbed up the kitchen roof from the outside, tied a rope to a wooden pole and went up and down into the kitchen, and fled from the same way after committing the crime.

After identification, the fingerprints and footprints did not match Xu Derong at all. As a result, Xu Derong was released from lien.

So, who left the footprints and fingerprints? This question should be answered by another investigator.

Meng Guang, the deputy leader of the group, da Liu, Xiao Huang, and Xiao Zhang, the investigators, divided their work to investigate the person who wrote the report letter, and after analyzing it, they believed that the letter writer was so familiar with Xue Nali's situation, and he was also familiar with Xue Nali's whereabouts, so it could be preliminarily concluded that this person was Xue Nali's colleague. So they decided to check the person who wrote the anonymous report letter, straightened out their thoughts, and decided to find out first that the director of the infirmary first knew that he sent Xue Nali to the district love committee to get publicity materials that day, and the director said that he first sent another nurse, Wang Yunli, who said that her feet twisted yesterday, and suggested sending Xue Nali, so he sent Xue Nali, Xiao Xue was very happy at the time, saying that she just had a movie ticket for 5:30 p.m. to send to her mother. Xiao Wang was next to him at the time, so she must have known. So, what is the relationship between this little king and Xue Nali? The director said that the two were as good as sisters before, but then they fell out over the matter of selecting and training doctors, and the relationship suddenly became like water and fire.

Originally, according to the increasing number of employees in the mill, the factory department decided to increase the number of medical personnel, and the doctors at that time did not need any qualification certificates, and the factory doctors did not pay much attention. The factory department decided to select one of the nurses who had worked for three years to be sent to the hospital for training, and came back as a doctor. There are a total of 7 nurses in the factory infirmary, 6 of whom are qualified, and everyone signs up, which is extremely enthusiastic, and they are all determined to get the frame. Because doctors and nurses are not only treated very differently, but also have very different reputations, no one has this opportunity to carry forward the style and be polite to others. Among these 6 people, Xue Nali, Xiao Wang and another Xiao Guo usually performed well, especially Xue and Wang, and all the conditions were suitable. Xue and Wang themselves knew it, but there was only one quota, so they began to compete viciously. The two first looked for mistakes in each other's work, turned out Chen Guzi's rotten sesame seeds, and then quarreled in person, and even almost fought at one time. The director of the infirmary was angry and decided to disqualify the two men and send Xiao Guo instead.

This was last year, half a month ago, due to the need to prepare for the establishment of a branch factory, the factory department decided to retrain a factory doctor, still selected from the nurses. This news has not yet been officially announced, but everyone already knows that Xue Nali and Wang Yunli have already talked to the leaders and expressed their intention to strive for it.

By the time the investigation was in progress, Old Don had made the most valuable discovery to date on the kindergarten kitchen skylight. When the special case team met that night, they summed up the information obtained by the two roads, and Sudden Sheng wondered: Will this matter have anything to do with that Wang Yunli? Of course, the footprints and fingerprints do not need to be compared, it is male, but if it is really her who plans the case, it can be asked to do it.

So he set his sights on Wang Yunli, and as soon as he learned, she had a boyfriend, who was already engaged, named Gaijie, who worked in a bank. The reconnaissance tentacles quietly reached out to Gaijie. The investigation learned that the young man was 24 years old, born a capitalist, liked martial arts since childhood, had specially visited a master to practice boxing, and his hands were agile; his family lived in the third district of Shunfeng Street, a character alley, and there was a man who walked the streets and alleys to sell rat poison. After investigating the man, two days before the case, Gaijie had bought zinc phosphide rat poison from him and bought five packs at once. That man wondered if he didn't buy it like this, don't use it for other goals? Just as he was about to ask a question, Gaijie had already opened his mouth to explain, saying that it was a troublemaker in the bank where he worked, and that the leader had asked him to buy it. The investigator then went to the bank again and proved that the explanation was false.

Down, it is to summon Wang Yunli and Gai Jie. After arriving at the case, first extract Gaijie's footprints and fingerprints, and the young man will know whether it is good or not. Before the appraisal conclusion came out, the two men separately confessed the facts of the crime, and their motives and processes were exactly the same as the special case team speculated. Subsequently, the conclusion of the technical appraisal also came out, confirming that the footprints and fingerprints found at the scene were indeed left by Gaijie.

Although there were a large number of victims in this case, because the perpetrator did not have a subjective motive for homicide when he planned it, and the consequences of the crime were not serious, and the confession attitude of the two criminals was also good, the court fully considered it in the judgment and sentenced him to 7 years and 10 years in prison respectively.
