Why did Lin Senhao kill Huang Yang?

1. Why did Fudan Lin Senhao poison himself?

Lin admitted the poisoning at the Shanghai No. 2 Intermediate People's Court trial, but said it was a coincidence. On March 29, 2013, Lin Senhao was doing an experiment with his classmates. On that day, he remembered the medicine left over from the last experiment. It happened that that day in the dormitory, Huang Yang was playing games with other students and mentioned that April Fools' Day was coming soon and he wanted to come up with a show to prank everyone. Lin Senhao saw him smiling proudly at that time, and then he remembered that he had heard that poison was used to punish people in other schools, so he thought to himself that he should poison Huang Yang first, and the purpose of poisoning was to give the victim a cure. An April Fool's joke to make him feel uncomfortable.

The above is Lin’s defense. In fact, Lin had planned it for a long time!

2. The prosecutor summarized the motive as "Lin had a discord with Huang due to trivial matters in life and was dissatisfied."

However, the police and prosecutors have never made it clear what the specific content of "trivial matters" is.

3. Lin Senhao

1. Lin Senhao (Lin Mu, Lin Mu), Ultrasound Department, Zhongshan Hospital Affiliated to Fudan, Vice Chairman of the Student Union, Sun Yat-sen University's exempted student, got the first place Three *** Pharmaceutical Scholarship. The research trend is on the liver, and the performance is also quite good. Undergraduate degree from the School of Medicine of Sun Yat-sen University, and was assigned to study for a PhD at Zhongshan Hospital.

In Lin's character, the self-respecting, motivated, strong, and kind half has never stopped fighting against the depressed, self-blame, and frustrated half. He tried hard to communicate with the outside world in his own way, but it was always difficult to find an outlet. This one-man war ended in destruction.

2. At noon on March 31, 2013, Lin decided to poison. The target was his roommate Huang Yang, a graduate student at Fudan University School of Medicine.

At this time, there was no one else in Room 421, Building 20, Xiyuan, Fudan University School of Medicine. The two permanent residents - Lin and Huang Yang - have been interning in the hospital for many years, and few classmates come here to visit.

Lin took out the reagent bottle, which contained the N-dimethylnitrosamine solution smuggled back from the laboratory. This is a light yellow oily liquid, highly toxic, odorless, and easily soluble in water. Lin has been storing this deadly poison for a long time.

He is familiar with this reagent. Over the past three years, Lin has injected this reagent into hundreds of rats to create samples of liver fibrosis, and then killed them to collect data.

Poison is injected into the sink of the water dispenser next to the dormitory door, and it will no longer be the rat that is killed.

3. In the memories of classmates and friends, Lin was once the director of the academic department of the Undergraduate Student Union. He had amazing scientific research ability and published more papers than ordinary students. He was enthusiastic about the activities of the hometown association, loved to play basketball, and played Three Kingdoms. , even good at telling cold jokes.

What they saw was a tall and lanky boy who was actively planning his life, a little shy in public, but good at communication and cooperation in his own circle. But even in Lin's circle, most people have never noticed other qualities of Lin. Few people know that Lin has been using a unique way to deal with long-term frustrations in communicating with the opposite sex; few people pay attention to Lin's habit of using extremely offensive and insulting sentences on the Internet - whether to his classmates or to others. He is still a public figure; as for Lin's family - which is actually a quite ordinary civilian family - and his hometown, Lin is even more careful to hide it from the topics of communication with others.

Few people have ever experienced that the two completely different sides have been suffering and fermenting in Lin's heart for a long time - although Lin has always talked about and dismissed them in a way that is difficult for others to detect. These unknown qualities together form a forest hidden from sight. Is it this invisible person who killed his roommate?

4. Water fountains and water stamps

In fact, even the police have been puzzled by Lin's motive for poisoning. After being taken away by the police, Lin confessed to the poisoning but was evasive about his motive. Lin once claimed to the police that the poisoning was an April Fool's Day joke, which made it difficult for investigators to believe him. But Lin mentioned at least one altercation involving a water fountain to police.

Lin once had a dispute with Huang Yang and another roommate Ge Lin (pseudonym) over water stamps. Huang and Ge proposed that the three of them share the cost of purchasing bottled purified water equally, but Lin refused. He pointed out that he drank less and the split method was unreasonable.

The dispute ended with Lin quitting the stall and "buying water for himself." Lin's classmates recalled that around March 31, Lin began to go in and out of the next door dormitory to borrow water. But this dispute probably only intensified existing conflicts.

As early as half a year ago, Lin deleted "Huang Yang" from the QQ friend list, and Huang Yang also deleted Lin at that time. Two roommates who lived in the same room were no longer among each other's online contacts.

Ge Lin could not recall why the two "broke off" online at that time, but it was confirmed from other sources that Lin stole the lethal reagent from the laboratory in the following six months.

5. On April 7, Huang Yang began to have nasal bleeding and fell into a coma the next day. The hospital was helpless. Until April 9, Huang Yang's senior brother received a text message reminding him of a certain drug.

The text message was once speculated by the public to be from Lin, but the text message actually came from another student who was using reagents for experiments. Huang Yang's sudden deterioration of his condition reminded him of the rats in the experiment. This conjecture It was quickly confirmed. On April 11, Lin was taken away by the police and quickly admitted the fact of poisoning.
