Just came the news that Zhu Ling, a victim of Tsinghua's "thallium poisoning", died of a brain tumor in Beijing on December 22 after being tortured by sequelae for 29 years.
Between 1994 and 1995, Zhu Ling, who was studying at Tsinghua University, was poisoned twice and was in a coma for two months. Although his life was saved, his body was severely damaged and he lost his ability to take care of himself.
Zhu Ling's roommate was once listed as a suspect, but the case has not been solved so far.
Thallium is a colorless, odorless, highly toxic chemical that can wreak havoc on the human nervous system. The use of thallium to harm people is not uncommon in the world, and a Chinese student once poisoned his roommate in the United States.
Juwan Royal, a tidal college student, is a sunny big boy who attends Lehigh University in Pennsylvania, USA.
Like millions of American college students, Zhu Wan left his family and moved into a university dormitory, where he met Yukai Yang, a Chinese student.
Although Zhu Wan and Yang Yukai are of different ethnicities, they get along with each other day and night, and they also get along as buddies, and the relationship is not bad.
Yang Yukai majored in chemistry, and his grades in the class were excellent, and he was regarded as a "top student" by his classmates, and his transcript was almost perfect, Zhu Wan also envied Yang Yukai's academic Xi and took it as an example and goal to motivate himself to study Xi.
The days were spent in a busy way, and the two were safe and sound, looking up and not looking down.
In February 2018, the spring in Pennsylvania was cold, and everyone nested in the dormitory to escape the cold, and Zhu Wan was also one of them, so he ate while studying Xi.
But the more he ate this meal, the more wrong it became, and Zhu Wan suddenly felt blurred and delirious, and his whole person was top-heavy. He didn't have time to react to what had happened to him, when he suddenly felt a darkness in front of him, and the whole world was spinning, his legs were weak, and he fell to the ground with a thud.
When he opened his eyes again, he didn't know how long it had been, and Zhu Wan woke up to find himself lying on the floor of the dormitory, and the sensation of his hands and feet gradually recovered.
After feeling that he could move slowly, Zhu Wan touched his mobile phone and dialed the ambulance.
Zhu Wan, who was sent to the hospital for treatment, did not get better, but became more and more serious. Two months later, Zhu Wan's parents took their son back to New York to recuperate and transfer him to a hospital for examination and treatment.
However, when the results of the examination came out, the whole family was shocked - thallium poisoning!
In fact, before fainting, Zhu Wan had been constantly experiencing physical abnormalities, and at first he thought he was eating a bad stomach, but he didn't expect it to be poisoned.
Not long ago, Zhu Wan was in the dormitory to catch water to drink, and the moment he drank it, his tongue was hot, and it seemed that he was not drinking water, but a bowl of spicy soup, and he immediately rushed to the toilet to rinse his mouth frantically.
The pain was slightly relieved at the time, but it recurred a few days later.
Zhu Wan thought that there was a problem with the water pipe, and kindly reminded Yang Yukai and asked him to pay attention to it.
Immediately afterwards, a few weeks before he fainted, Zhu Wan found that he had a rash all over his body, and when he lifted his clothes, he saw that there were all small red spots, which was very infiltrating.
In just 2 months, Zhu Wan's weight plummeted by about 20 pounds, and he either couldn't swallow anything at all, or he didn't dare to eat.
Forget it, Zhu Wan felt that his heart was not normal, went to the hospital for examination, and once wore a heart detector for 1 month, and during this period, he had new symptoms: vomiting did not stop.
Because he vomited all night, Zhu Wan was rushed to the hospital.
To make matters worse, the stinging sensation that I had only felt in my tongue gradually spread to my limbs, "as if someone had taken 100 knives and stabbed me in both feet." ”
Gradually, Zhu Wan, a male college student who was originally alive and kicking, became a sick patient, and poor Zhu Wan even had problems sleeping and walking normally.
The pain tormented Zhu Wan day and night, and he once wondered if he was going to have his leg amputated.
He never imagined that he was actually thallium poisoning.
You may not have heard much of the term thallium poisoning, which is a toxic reaction that occurs when the body ingests thallium-containing compounds.
The rat poison, which is called "highly poisonous" in the world, contains thallium.
For mammals, the toxicity of thallium is higher than that of metal elements such as lead and mercury, and the minimum lethal dose for adults is 12mg/kg and for children is 8.8~15mg/kg.
The symptoms of thallium poisoning are numbness or pain in the lower limbs, low back pain, hair loss, headache, mental restlessness, muscle pain, tremors of the hands and feet, unsteady walking, etc., Zhu Wanquan was hit.
He began to wonder how he could ingest such a large amount of thallium, an element that is not common in daily life.
Zhu Wan's parents initially suspected that something in the dormitory was poisonous, and immediately called the police.
As soon as the police investigated, they immediately set their eyes on Zhu Wan's Chinese roommate, Yang Yukai.
When Zhu Wan first became unwell, he reminded Yang Yukai, and at that time he said that someone might have poisoned him, and said that "this toxin should be colorless, odorless, and easily soluble in water."
Zhu Wan was also worried that this was the case, and then called the police, who were suspicious at the time.
Because at that time, Zhu Wan's symptoms were only red rashes and stinging pains on his body, and when he saw this symptom, he would be a rash or something, but Yang Yukai was directly poisoned, and he also expressed suspicion that someone had poisoned his roommate's mouthwash and milk in the dormitory refrigerator.
Not only that, Zhu Wan once found a racist graffiti on the bed, which was written "N****, get out of here!"
In this regard, Yang Yukai said that he did not know, saying that he went out that day and was not in the dormitory.
After comparing the graffiti and Yang Yukai's handwriting, the police found that the similarity was very high.
After feeling clues, the police finally detained Yang Yukai, but he immediately paid bail, and then bought a plane ticket to escape back to China.
The police contacted immigration and customs and arrested him just as he was about to flee.
In the end, Yang Yukai confessed to his crimes, admitting that he mixed thallium with drinks and food for Zhu Wan to take, but argued that he had bought chemicals online in case he committed suicide.
So why did Yang Yukai finally use this medicine on Zhu Wan's body?
According to reports, Yang Yukai's reason for poisoning his roommate is incomprehensible: in order to get Zhu Wan's attention to himself?!
Yang Yukai is a typical Asian student in the eyes of people, with excellent grades, a somewhat shy personality, almost withdrawn, striving for perfection in everything, and suffering from "schizotypal personality disorder", which does not usually talk to people.
In college life, the cheerful Zhu Wan is a person who can understand and listen to him.
According to court documents, Yang Yukai is psychologically dependent on Zhu Wan, and to a certain extent, Zhu Wan meets his social needs.
A few weeks before Zhu Wan's poisoning, Yang Yukai had been worried about his grades, and he went crazy in the dormitory to study Xi, and even used furniture and boxes to prop up a wall between the two beds, trapping himself inside, often depressed and restless.
And before that, Zhu Wan told Yang Yukai that he was going to move out, which was probably the last straw that crushed him.
Yang Yukai admitted that he had tried to commit suicide many times because of the huge pressure on his original family, and wrote a 6-page "suicide note".
After hearing the news that Zhu Wan was going to move out, Yang Yukai, who collapsed, turned his attention to him and poisoned him.
Frank Dattillio, a psychologist who participated in the courtroom evaluation, analyzed that Yang Yukai suffers from schizophrenia, and this seemingly illogical approach is one of the symptoms: "He believes that enough chemicals are added to the food to get Zhu Wan's attention." ”
"He said to me, 'I know how many potions I need to put to kill him, because I know how many potions I need to put to end my own life'. ”
He said that Yang Yukai's approach was too terrible, and it was better to kill him than to kill him by poisoning Zhu Wan so much that he could not die.
"If he can hurt his best friend, he can hurt anyone. ”
In the end, Yang Yukai was sentenced to 7 to 20 years in prison and was repaled after being repatriated. In 2025, Yang Yukai will be released from prison on parole.
To this day, Zhu Wan still endures bone-crushing pain from thallium poisoning from time to time, and fears that it may accompany him for the rest of his life.
Regarding Yang Yukai's poisoning, Zhu Wan himself was relieved and forgave him, saying, "This is to let myself live well, so that I can get peace." ”
Whatever the reason, the poisoning is really terrifying, but in the past few years, similar incidents have been staged at home and abroad, making many people in the dormitory worry that they will make enemies, and they will be "killed" unconsciously...
