Three years after the Fudan poisoning case, on February 8, 20 15, 15, the Supreme People's Court informed the defendant Lin Senhao's father to meet him through the Shanghai No.2 Intermediate People's Court, and Lin Senhao was finally executed. Less than four days later, the case was finally settled. Judge explains why Lin Senhao was sentenced to death: In this case, the defendant Lin Senhao, as a graduate student majoring in medicine, should have used his professional knowledge to serve the society, and it should be his duty to respect and care for life. However, Lin Senhao was dissatisfied with the victim only because of daily trivia, so as to vent his anger, that is, he used his medical knowledge to deliberately put toxic chemicals into the water dispenser, deliberately killing innocent victims and ignoring others' lives. Lin Senhao's criminal circumstances are particularly bad, and the consequences of the crime are particularly serious. If the circumstances are particularly serious, he should be sentenced to death according to law. During the review, the defense lawyers have put forward some defense opinions. How did the Supreme People's Court review and judge these opinions? Judge: The defense lawyer suggested that the Judicial Appraisal Center of the Institute of Forensic Science and Technology did not detect dimethylnitrosamine in the urine sample of Huang Yang at first, while the Physical Evidence Appraisal Center of the Shanghai Public Security Bureau detected dimethylnitrosamine in the urine sample of Huang Yang collected by the Institute of Forensic Science and Technology. The test results of urine samples from Huang Yang by two appraisal institutions are contradictory. According to the Supreme Law review, the fact that the biological identification center detected dimethylnitrosamine in the urine sample of Huang Yang and the fact that Huang Yang died of poisoning after drinking water in the drinking fountain after Lin Senhao put dimethylnitrosamine in it can be mutually confirmed, and the testimony of relevant appraisers at the investigation stage has given a reasonable explanation for the difference between the two test results. The testimony was cross-examined in the court of first instance and was adopted by the courts of first and second instance, so the defense opinions of defense lawyers were not adopted according to law. (Xinhua News Agency) Judge of the Supreme Court: the Supreme People's Court confirmed through review that the defendant Lin Senhao and the victim Huang Yang were 20 10 graduate students of Shanghai Medical College of Fudan University, respectively, and lived in the same dormitory. Lin Senhao was dissatisfied with Huang Yang because of daily trifles, and decided to poison Huang Yang. On the afternoon of March 3, 2065438, Lin Senhao managed to take out the reagent bottle and syringe containing the residual toxic chemical dimethylnitrosamine from the imaging medical laboratory of Zhongshan Hospital affiliated to Fudan University. At about 7: 50 on the same day/KLOC-0, Lin Senhao took advantage of nobody in the dormitory to put reagent bottle and the dimethyl nitrosamine stock solution in the syringe into the water dispenser in the room. At 9: 00 on April/KLOC-0, Huang Yang vomited after drinking water from the water dispenser, and went to Zhongshan Hospital at noon that day. In the following days, Huang Yang went to the hospital several times, and his condition deteriorated, and he was transferred to the intensive care unit for treatment. 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 dimethyl nitrosamine into the water dispenser. 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.
