Murder of Jiang Ge

The murder of Jiang Ge occurred in Nakano, Tokyo, Japan, on 3 November 2016. Jiang Ge, a 24-year-old graduate student from China at Hosei University, was stabbed to death by Chen Shifeng, a 25-year old Chinese national, just outside her apartment. The case was controversial in China after it was discovered that Jiang's roommate Liu Xin, who initially claimed that she did not know the identity of the murderer, was the murderer's ex-girlfriend. It later emerged that before the murder Liu asked Jiang to accompany her home as she was afraid of Chen. When Chen appeared she entered the apartment before Jiang, locked the door behind her, and called the police. Liu was heavily criticised in the Chinese media for failing to assist Jiang.
