On the evening of January 7, a reporter from Beijing News visited the dormitory of Tan Dawei, a deceased student. It was located on the 4th floor of an apartment building in Xianlin Campus, with the door locked. According to the students in the dormitory next door, Tan Dawei has lived here since he was a graduate student. On December 27, the day after Tan Daweis accident, his roommates have all moved away.
The dormitory where Tan Dawei lived before his death is now locked.
A person familiar with the matter told reporters that Tan Dawei and his classmates had been criticized by his mentor Zhang Hongmei on the afternoon of December 25. Later, he learned that someone saw the monitoring video of the dormitory on the day of Tan Daweis accident. When Tan Dawei left the dormitory for the laboratory, he took a lighter from the dormitory. He lit the lighter when he went out.
