Lin Senhao's character events.

On April 20 10/3 16, Huang Yang, a graduate student of Fudan University, died of acute liver injury after being rescued. The police informed that N-dimethylnitrosamine, a toxic compound, was detected in the residual water of students' drinking fountains. On the morning of April 13, Shanghai police confirmed that Lin Senhao, a roommate of poisoned graduate students, was suspected of committing a major crime and had been detained in criminal detention.

Lin Senhao and Huang Yang are both 20 10 graduate students of Shanghai Medical College of Fudan University, and they belong to different medical majors.

Since August 20 10, Lin Senhao has been living in Room 42 1 in a dormitory building of Fudan University. A year later, Huang Yang was transferred to the dormitory. Later, Lin was dissatisfied with Huang because of trivial matters, and gradually became bitter.

On March 29th, 20 13, Lin Senhao listened to Huang Yang and other students teasing that April Fool's Day was coming and wanted to play tricks on people.

2065438+20 10 At noon on March 3 10, Lin Senhao, a graduate student of Fudan University, took the toxic compounds left over from his experiments and stored them in the laboratory to the dormitory and injected them into the water tank of the drinking machine.

On the morning of April 6th, 2065438, Lin Senhao's roommate Huang Yang got up to drink water. After drinking it, I vomited, and finally I was admitted to the hospital because of my discomfort.

On April 1 1, 2003, the Cultural Security Branch of the Shanghai Public Security Bureau received a report from the Security Department of Fudan University about the poisoning incident in Huang Yang. After receiving the report, the Shanghai police immediately organized a task force to carry out the investigation. After on-the-spot investigation and investigation, Lin, a classmate in the dormitory, was suspected of committing a major crime and issued a criminal summons to Lin in accordance with the law that night.

On April 2013 12, Lin was criminally detained by the police according to law.

20 13, 16, on the afternoon of April 20th, Huang died in a hospital in Shanghai at 3: 23 pm that day.

On the afternoon of April 19, 2065438, Shanghai police formally applied to the procuratorate for approval to arrest Lin, a suspect in Fudan University's "4 1" case, on suspicion of intentional homicide.

On October 8th, 2065438+ 16/kloc-0, Tang Zhijian received a letter addressed to their lawyers before the execution of the death penalty. According to the signing time, the date is 2015 65438+February 9.

Write a letter to a lawyer: The rule of law in China will become wider and wider.

In this handwritten letter, Lin Senhao wrote: Thank you very much for your help in my case and my life. Good people are rewarded, please believe! In this case, what has happened is irreversible. Please let go, protect yourself, and don't do things that are not conducive to your career and life. Meaningless! Remember, remember!

Lin Senhao also said in his letter that the road to the rule of law in China will be wider and wider, and you (lawyers) need to shine. Bless you!

The inscription on the back is "Student: Lin Senhao". Suspect's behavior is abnormal

From March to April of 20 13, it was found that the suspect Lin Senhao seemed to be under great pressure, showing his worries and troubles about reality, and did not take the doctoral examination. I also said in Weibo that I was unhappy with my tutor and planned to go back to my hometown.

On April 8, 20 13, Weibo, who was arrested before detention, said that he sometimes hated the profession of doctor because "in the face of patients who are eager to solve their doubts from here, help can never be the last".

The suspect pretended to be calm.

After Huang Yang was sent to Zhongshan Hospital for "acute liver injury", Lin Senhao, a criminal suspect who was suspended here, personally performed a B-ultrasound examination for Huang Yang and told Huang Yang that he was fine. Later, I personally took the fruit to visit.

Huang Yang's father rushed to Shanghai from Chongqing after his son was admitted to the hospital. He shared a dormitory with the suspect that night and found nothing unusual. Dad Huang went to the dormitory to get something, and the suspect skillfully showed him what it was. On another occasion, the suspect met Huang's father by bike and asked if he was getting better after getting off the bus.

"I only learned yesterday that Lin Tongxue, whom I have seen, poisoned me." Dad Huang said, "We didn't expect him to do it at all. I haven't figured out why. " Huang Yang changed the dormitory several times, and only 20 12 lived in this dormitory with the suspect.

The suspect showed his tail.

On April 9, 20 13, my elder brother received a short message from a stranger reminding him of a chemical. Sun immediately told his tutor about the situation and inquired about the medical papers of the school. It is found that the experimental symptoms of the drug in mice are very similar to those before Huang Yang, and the author of the related experimental paper is Lin Senhao.

The source of the suspect's poison

As for the source of N- dimethylnitrosamine poisoning Huang Yang, it was found that it came from the laboratory of hospital imaging center. This drug is used in the laboratory to do mouse model tests. The suspect is half an expert in this field. The suspect has done experiments on this drug with mice before and has written 7 related papers.

After the incident, the police took the suspect to the laboratory to identify the scene. Earlier, the internal meeting of the laboratory had informed that this drug was discovered less than half a year, a few days ago. "Although the laboratory stipulates that drugs can't be taken out, it's not that difficult if you want to bring them."

Motivation and purpose of crime

The court verdict found that the suspect deliberately poisoned and killed people because of trivial matters. The suspect was angry and dissatisfied with poisoning. This is related to the suspect's jealousy, inferiority, sensitivity, fragile personality defects and low ability to deal with interpersonal relationships and emotional adjustment. People with these negative factors are vulnerable to setbacks in life, and setbacks often make them experience negative emotions such as anger, resentment and hostility, which cannot be ruled out for a long time. When they accumulate to a certain extent, if they are stimulated by even a small thing, they will have an emotional attack, leading to out-of-control behavior and committing crimes and hurting the victims. 20 14 02 18 Shanghai No.2 intermediate people's court sentenced the defendant Lin Senhao to death for intentional homicide.

The court held that the defendant Lin Senhao deliberately poisoned the victim Huang Yang to vent his anger, which constituted the crime of intentional homicide and should be punished according to law. The defendant is a graduate student majoring in medicine, who used dimethylnitrosamine to participate in animal experiments and research. He knew that dimethyl nitrosamine was a highly toxic substance, and deliberately put this toxic substance into the water dispenser, which led to Huang Yang's poisoning after drinking it. During his stay in Huang Yang, the defendant deliberately concealed the cause of Huang Yang, which eventually led to Huang Yang's poisoning death.

The court pronounced that according to the Criminal Law of People's Republic of China (PRC), the defendant Lin Senhao was guilty of intentional homicide, sentenced to death and deprived of political rights for life.

The parents of both parties involved shed tears at the trial site. The defendant's father said that he would appeal.

After the judgment of the first instance, a petition on not sentencing Lin Senhao to death and another statement signed by Fudan University 177 students were sent to the Shanghai Higher People's Court. It is suggested that the defendant be given a chance to turn over a new leaf and take care of the parents of the victim Huang Yang in the future. 20 14 12 8. The Shanghai Higher People's Court publicly retried the Fudan poisoning case. The trial lasted 13 hours, and the second trial ended at about 1 1: 30 in the evening. The judge announced an adjournment and decided on another day.

On the morning of 2065438+200518, when the Shanghai Higher People's Court publicly pronounced the case of Lin Senhao, the defendant in Fudan poisoning case, the prosecution believed that the facts were clear and the conviction was accurate, and hoped that the court would dismiss his appeal and uphold the original judgment. The representative of the agent ad litem in this case expressed the hope to maintain the judgment of the first instance.

The Shanghai Higher People's Court publicly pronounced the case of the defendant Lin Senhao's intentional homicide appeal: it ruled that the appeal was dismissed and the original judgment was upheld. The death penalty will be submitted to the Supreme People's Court for approval according to law.
