Yang Shuming
[2] Many of his victims wore red clothing while they were assaulted, leading to some media outlets referring to him as The Red-Clothed Killer.He was also noted for his good work ethic, being employed by the Shanxi Yangquan Coal Mining Group as a welder for over 10 years at the time of his arrest.[4][5] On the evening of 2 March 1992, 16-year-old Zhong Rui got off a bus with two coworkers after finishing her shift at the fertilizer factory she worked at.After parting ways with her coworkers, she continued to walk down a dimly-lit street when Yang, armed with a knife, stabbed her in the back from behind, piercing her heart.Police later linked the murder to an attack on a 24-year-old woman five days later, but they still lacked enough evidence to make progress in the case.[6] During the early morning of 11 July 1992, Li Xin, a 23-year-old woman, was taking her daily route to her apartment building after finishing work.In addition to being stabbed multiple times, the victim's stomach had been cut open, and her face and nipples had been mutilated.However, due to the places where Guo's remains were found, as well as the short time between the discoveries, investigators changed their minds, now believing that the murderer was a local who had lived in the community for more than a decade.[6] At 9:00 p.m. on 24 November 2004, Tang Rui, a young supermarket employee, began to walk home from her job.Although he did not typically target men over fear of being overpowered, and the lack of pleasure he received from stabbing them, he decided to attack the man because he could not find any other potential victims.[7] Police, still unable to identify the perpetrator, contacted Ding Tongchun, a psychology professor at the People's Public Security University of China, for help in their investigation.
