1. the Supreme People's Court confirmed through examination that the defendant Lin Senhao was dissatisfied with the victim Huang Yang because of daily trivial matters and decided to poison Huang Yang. On the afternoon of March 3, 2065438, Lin Senhao borrowed the key from others on the pretext of taking things, and then entered the imaging medical laboratory on the 204th floor of Zhongshan Hospital affiliated to Fudan University 1 1, and took out the remaining toxic chemicals stored here after he participated in the medical animal experiment on 201. At about 7: 50 on the same day1,Lin Senhao returned to Room 42 1 with the above-mentioned items, put the dimethyl nitrosamine stock solution in reagent bottle and syringe into the water dispenser in this room by unmanned machine, and then put reagent bottle and other things into yellow medical waste bags and discarded them in the trash can outside the dormitory. At 9: 00 on April 1 day, Huangyang took water from the water dispenser in Room 42 1 day, and vomited. He went to Zhongshan Hospital at noon that day. On the afternoon of April 2, Huang Yang came to Zhongshan Hospital again. After the examination, I found that my liver function was damaged, so I was hospitalized for observation. On the afternoon of April 3rd, Huang Yang became seriously ill and was transferred to the hospital intensive care unit for treatment. From then until April 1 1, including when he was investigated and questioned by public security personnel, Lin Senhao never told the truth. At 0: 00 on April 12, after the public security organ confirmed that Lin Senhao was suspected of committing a crime and summoned him, Lin Senhao truthfully confessed the fact that he had put dimethylnitrosamine into the water dispenser in Room 42 1. On April 16, Huang Jing died after being rescued. According to forensic identification, Huang Yang died of acute liver failure caused by acute liver necrosis caused by dimethylnitrosamine poisoning, and then multiple organ failure.

2. the Supreme People's Court believes that Lin Senhao, the defendant, knew that dimethyl nitrosamine was a highly toxic chemical and was seriously harmful, and put a large dose of dimethyl nitrosamine stock solution into the water dispenser, causing the victim to be poisoned after drinking water. When the victim was admitted to the hospital, especially when he was transferred to the intensive care unit for treatment, Lin Senhao still deliberately concealed the truth, fabricated lies, and intentionally killed and poisoned people, which constituted the crime of intentional homicide. Lin Senhao's dissatisfaction with the victims is only due to the daily trivia, that is, he used his medical knowledge to deliberately put toxic chemicals into the water dispenser and killed the innocent victims. The circumstances of the crime are particularly bad and extremely serious, and should be punished according to law. Lin Senhao always confessed the facts of the crime after he was brought to justice, and his guilty attitude was good, but it was not enough to be given a lighter punishment. The facts ascertained in the first-instance judgment and the second-instance ruling are clear, the evidence is true and sufficient, the conviction is accurate, and the sentence is appropriate. The trial procedure is legal. Accordingly, the Supreme People's Court approved the Shanghai Higher People's Court to uphold the criminal ruling of first instance, sentenced the defendant Lin Senhao to death for intentional homicide and deprived him of his political rights for life.
