In 1998, a gruesome tragedy occurred in the Tianjin area, when a female high school student killed 6 roommates because she was afraid of loneliness after death.
After the investigators investigated, the only survivor in the dormitory was sentenced to life imprisonment.
First, a disaster, killed 7 people
On the night of December 22, 1998, the lights in the dormitory building were turned off as usual, and most of the girls had washed up and were ready to go to bed.
A girl who lives next door to dormitory 113 always feels a pungent smell and can't sleep when she lies on the bed.
Later, because the girl couldn't stand it, she got up and checked it out, and found a pungent smell coming from the 113 dormitory next door.
The girl was afraid of what messy things were doing in the dormitory next door, and in the company of her roommate, she went to the building manager's aunt and asked her to go over to check what happened in the 113 dormitory.
At that time, it was close to late at night, ordinary students were already asleep, the building manager aunt had been busy for a day, and her mental state was also very poor. After being woken up by several girls, she was in a very bad mood, did not want to toss in the middle of the night, and advised several girls to endure for a night and wait for the next day to check the situation.
Everyone thinks that it is only one night, there will be no accidents, and the development of the facts has surprised everyone.
At six o'clock the next morning, the girls got up to wash up and prepare to go to the class for morning self-study, and the irritating smell of last night was still very strong.
The girls who lived next door got up and came to the 113 dormitory to look at it, only to find that there was a person at the door who was gulping in fresh air, looking panicked and giving people a special feeling.
The girls instinctively felt that there must be something wrong with dormitory 113 and looked inside the door. Suddenly, a scream sounded: "Dead man! Dead man! ”
Some people with less courage are directly paralyzed on the ground and can't help but shiver. I don't blame the witnesses for being timid, but the scene in the dormitory is too weird.
There were originally 8 people in the 113 dormitory, in addition to Sun Yayu, who ran to the door to breathe fresh air, the other 7 people were scattered in all corners of the dormitory, each person's expression was painful and vicious, there was still a large amount of white foam at the corner of the mouth, and some people even had signs of urinary incontinence.
Obviously, those who have died tragically have suffered greatly before they died. The screams of the girls soon attracted the attention of everyone. When aunt Lou Guan and her husband heard the news, they were frightened by the scene in front of them. They hurried to call the police and contacted the school leaders at the same time.
Second, the investigation was launched, and the survivors became suspects
Soon after, the case-handling staff rushed to the scene with an ambulance and sealed off the entire dormitory building. At this time, the school leaders who arrived in advance had properly arranged for the girls who witnessed the scene of the crime, and also issued a gag order to other insiders present in an attempt to prevent the dissemination of information about the case. Unfortunately, the effect is not very good.
Although the students did not have particularly rich social experience, the arrival of police cars and ambulances made them realize that something big had happened in the dormitory building, and it was likely to be a murder.
Everyone is very taboo about this kind of thing, and actively chooses to avoid it, trying not to cause trouble to school leaders and case-handling personnel.
After inspecting the on-site environment, the case-handling personnel and forensic doctors have a preliminary judgment based on their years of work experience. The pungent smell in the house should come from a pesticide. The 7 girls who unfortunately died were most likely poisoned to death.
When the case-handling staff and forensic doctors collected on-site information, the parents of the 8 girls also came to the school.
Parents have been looking forward to the healthy growth of their children, and this bad news is like a thunderbolt on a sunny day for them.
Looking at the scene of the tragic death of the children, the hearts of the parents, like a knife cut, cried uncontrollably, and some even fainted from crying because they were too painful.
The case-handling personnel have a special understanding of the parents' feelings, but the investigation of the case must continue, and the truth of the matter must be ascertained in order to comfort the spirit of the victims in heaven.
With the consent of the parents of the victims, the case officers and forensic doctors sent the children's bodies away for autopsy.
In order to grasp more clues and avoid missing important information, the case-handling personnel also temporarily detained the building manager couple and the canteen cook who were responsible for duty. After interrogation and investigation, neither the building manager nor the canteen cook had anything suspicious.
The louguan couple said that they had no vendetta against several girls who had unfortunately died in the near future, and there was no reason to kill them.
Besides, they are not desperate outlaws, they are ordinary people with old and young, working in the dormitory just to eat a mixed meal, even if they occasionally have a little unpleasant friction with the students, they will not do such a crazy bad thing.
When the canteen cook was detained, he also felt that he was very aggrieved, and his situation was similar to that of the building manager couple. He works in the school cafeteria, also to earn some hard money, to take care of the family, and has no motive to commit crimes.
If the canteen cook really poisoned the food, there would definitely be a large number of students who would be victimized, and it would not be possible for only 113 dormitories to have accidents. Therefore, the case-handling personnel successively released the building manager couple and the canteen cook.
Since other relevant personnel are not suspected, the root cause of the problem is likely to be in the 113 dormitory. Therefore, the case-handling personnel turned their suspicious eyes to the only survivor, Sun Yayu.
As a witness, she must know what happened in the dormitory, and if you can get some clues from her, the facts of the case should be able to figure out.
Third, the case gradually became clear, and human and physical evidence appeared one after another
Because of his previous strange experience, when Sun Yayu was questioned and investigated, his mood has been unstable. In order to avoid irritating her spirit, the case-handling staff did not take too harsh measures against her.
When Sun Yayu was investigated, the forensic doctor's examination report also came out smoothly. The results of the report showed that the 7 girls who unfortunately died were indeed poisoned by drugs.
The culprit that led to their deaths was a substance called methoxyphosphorus, a highly toxic pesticide that can cause severe symptoms if the average person accidentally takes a dose of only 2 milligrams.
Poisoned people will have respiratory failure and pulmonary edema because of the effect of drugs, and if they do not get timely treatment, they will die if they persist for up to ten minutes. The remains of the victims at the scene of the crime also confirm this theory.
The case-handling staff recalled that when they first came to the scene of the crime, the body of a girl was very close to the door, and she should have wanted to escape desperately, but unfortunately, before she went out, she was killed by poison.
The forensic doctor said that this tragedy actually had a chance to avoid, 7 poisoned girls, although ingested a large dose of poison, but if they can be sent to the hospital for treatment in time, there is a certain chance to survive.
Because of this forensic evaluation result, Sun Yayu, who has a major suspicion in himself, has a few more doubts on his body.
According to eyewitnesses, Sun Yayu only came out the next morning. In other words, she has been in the room, witnessed the tragic situation of 7 housemates, and spent one night in the crime room.
No one knows what Sun Yayu thought at the time, but judging from the results, she is indeed inextricably linked to this case.
Considering that Sun Yayu's mental state was extremely unstable, the case-handling personnel still did not take compulsory measures against her at this time, but investigated and collected evidence on the appliances in the dormitory.
After the test results came out, the cups of the 7 victims were all left with the ingredient of methion phosphorus, and the cups also had Sun Yayu's fingerprints.
It was also at this time that the case-handling personnel got a new clue. The owner of a shop revealed that a few days before the incident, a female student came to the store to buy a bottle of pesticide.
Generally speaking, most of the people who go to the store to buy pesticides are older farmers, and few underage children buy this kind of thing. Therefore, the store was deeply impressed by this matter.
Since the store knows that the child's purchase of pesticides is abnormal, why didn't it stop it in time? In the face of the interrogation of the case-handling staff, the store smiled bitterly and explained that people who do business have a reason to reject customers.
He thought that the girl who bought the pesticide was helping her family to buy things, and he never dreamed that this would happen.
Because the matter of buying pesticides was only a few days later, the store recognized Sun Yayu as soon as he saw him.
Fourth, the absurd truth is creepy
All indications show that Sun Yayu, as the sole survivor, seems to be the murderer of this case. At this juncture, Sun Yayu suddenly opened her mouth, and she kept arguing, "It wasn't me who did it, it was Liu Shanshan who did it, I just helped, not what I wanted to kill." ”
Before, the case-handling personnel felt that the case had basically ended, and they did not expect that the case had another hidden plot. In order to thoroughly find out the truth, the case-handling personnel conducted a comprehensive interrogation of Sun Yayu, who had already regained some sanity.
Sun Yayu may be afraid of being charged with murder, and confessed all the information he knew.
The murderer identified by Sun Yayu, Liu Shanshan, is also a member of the 113 dormitory, and she has lost her life because of the previous poisoning incident.
According to Sun Yayu, before the poisoning incident, the relationship between the people in the dormitory was very good, and everyone went to school together, discussed various topics of interest, and occasionally mixed a few words, but there was no relatively large quarrel.
The reason why Liu Shanshan killed other housemates was because she had lost love. These two things seem to be incompatible, but they are forced together.
Liu Shanshan is a more emotional person, she liked her classmate Liu Mou because of the beginning of her love. Both are high school sophomores, knowing that they are heavy academics and should not fall in love too early, but they still can't help but come together because of love.
When the two were close, they looked sweet, but soon something went wrong. Liu mou somehow suddenly proposed to break up, Liu Shanshan was unwilling to end this relationship, and begged Liu to change his mind, but he still insisted on separating.
The blow of lost love made Liu Shanshan feel greatly stimulated, often crying inexplicably, and the other people in the dormitory saw her so painful, and her heart was not very good, often comforting her, hoping that she could cheer up.
When Liu Shanshan lost love, she was already in her third year of high school, and she would have to take the college entrance examination in about half a year. Everyone can squeeze time out of the heavy study, patiently persuade Liu Shanshan, in fact, it is quite difficult, the result of the kind persuasion of the housemates, instead of cheering Liu Shanshan up, she has an extremely terrible idea.
Liu Shanshan cried to Sun Yayu more than once that she was particularly desperate and did not know what it meant to be alive.
When talking to the case-handling staff about this detail, Sun Yayu's emotions also came up, and he explained with tears: In those few days, I have been comforting her and advising her to cheer up and not to think about it, but she can't listen to it, but she is getting more and more depressed.
On the day of the crime, Liu Shanshan found Sun Yayu again and pleaded with her: It is really not interesting to live, it is better to die, you are my best friend, can you help me.
Sun Yayu was frightened when he heard this, and hurriedly refused to say, This is not okay, I can't do it.
Liu Shanshan seemed to have realized this long ago, and pleaded with Sun Yayu, "No need for you to do it, you can help get the medicine, please, help me buy a bottle of pesticides, please."
It should be emphasized here that any attempt to harm and deprive others of their lives, whether by hand or with drugs, is seriously illegal.
Sun Yayu is an educated high school student, must know this truth, but because of Liu Shanshan's bitter pleading, the ghost made God agree to it, and really helped her buy a bottle of pesticides.
On the evening of December 22, Liu Shanshan saw that the other housemates had not returned, and made more outrageous requirements for Sun Yayu, she felt that she was too lonely on the road alone, and wanted Sun Yayu to drug the other 6 people and let the other people in the dormitory walk with her, so that Huangquan Road would not be too lonely.
At this time, if Sun Yayu stopped the horse from the cliff, she actually had the opportunity to avoid this tragedy, and as a result, she agreed to Liu Shanshan's request.
At about 10 p.m., the other 6 girls went back to their dormitories to rest after studying for the evening. Liu Shanshan secretly poured the pesticide into the empty bottle and lied to everyone, saying, "This is a medicine specifically for the prevention of tuberculosis, my parents bought it for me, everyone drank it together, and they will never get tuberculosis in their lifetime." ”
This reason looks outrageous, in fact, it just pokes at everyone's pain point. At that time, there were a few people in the school who unfortunately suffered from tuberculosis, and everyone was particularly afraid, always worried that the disease would entangle them. I heard that Liu Shanshan had a special medicine here, and everyone was immediately interested.
Liu Shanshan knew that the bottle was a fatal thing, and she was afraid that everyone would see through it, so she took a sip in front of everyone.
Several other people saw that Liu Shanshan had drunk it herself, and subconsciously felt that the potion in the bottle might really be a good thing to prevent tuberculosis, and she also drank a few sips.
Sun Yayu knew that the taste of the pesticide was very choking, and cut an apple to distribute to everyone, trying to cover up the taste.
After a few minutes or so, the drug reaction came up, a strong pain, stinging all the people taking the drug. Everyone realized that there was something wrong with what they had just done and had to escape as soon as possible, but they were stopped by Sun Yayu.
At that time, everyone else had taken their medicine, and were tormented by intense pain and almost lost their minds. Sun Yayu was the only one who did not drink medicine and was able to move normally, so she easily stopped the others.
When Sun Yayu recalled the details of this incident, she seemed particularly broken, and she cried bitterly and said that at that time, she was like a marionette, and she did not know why she would do such a terrible thing.
The case-handling personnel listened to Sun Yayu's confession and fell silent. No one expected that the truth of this case would be so absurd.
V. In the trial of cases, those who harm others will suffer the consequences themselves
In order to verify Sun Yayu's confession, the case-handling personnel conducted an investigation into Liu Shanshan's ex-boyfriend Liu Mou. Liu mou was very honest and explained the process of his interaction with Liu Shanshan.
In addition, the case-handling personnel also found a pre-written suicide note in the hidden corner under Liu Shanshan's bed. Liu's confession and suicide note under the bed corroborate Sun Yayu's testimony.
However, Sun Yayu did not get rid of the guilt, no matter from what position, she has an unshirkable responsibility for the unfortunate death of the other 6 girls.
Although Liu Shanshan, who is the main criminal, has lost her life because of her absurd plan, her parents still have to take responsibility for this matter.
After hearing the case, the judicial department held that Liu Shanshan and Sun Yayu's parents, as the guardians of the children, must be responsible for the case.
There are loopholes in the management of the school, and problems are not detected in time, and responsibility should also be taken. In the end, the three parties together compensated the victim's family with 1.5 million yuan.
Sun Yayu, who was a direct participant in the case, was not sentenced to death because he was under 18 years old at the time of the crime, but was sentenced to life imprisonment.
Insiders revealed that Sun Yayu, who was completely sober, particularly regretted what had happened before. After he was imprisoned, he has been very cooperative with the management. Every time I think of something that I used to do, I cry uncontrollably.
Some psychologists commented that Sun Yayu's original encounter caused her a great psychological impact. It may have left her with a shadow that is difficult to get rid of for a lifetime, and the nightmare of the past will haunt her for the rest of her life.
Later, Sun Yayu was given a reduced sentence because of his good performance in prison, and was sentenced to 15 years in prison.
Judging from the results, Sun Yayu was also greatly punished, but the fatal crime she committed at the beginning will not be written off.
What she did had caused several families to fall apart. She will spend the rest of her life repenting and atone for what she has done in the past.
