Gao Chengyong

Gao Chengyong (10 November 1964 – 3 January 2019) was a Chinese serial killer and rapist. He mutilated the corpses of his victims, leading to his nickname of the "Chinese Jack the Ripper" in Chinese media. He is thought to have killed eleven women between 1988 and 2002.

Sentenced to death and stripped of all his assets, he was executed by an undisclosed method in January 2019.

Murders
Over the course of 14 years, Gao raped, murdered and mutilated eleven women: ten in Baiyin, Gansu province, and one in Baotou, Inner Mongolia. His youngest victim was eight years old. The first murder is thought to have originated in a grocery store he managed with his wife in Baiyin. He would normally operate in daytime and follow his victims home, where he would strike.

Gao raped his victims sometimes while they were alive and sometimes after having stabbed them to death. He removed the reproductive organs of some women after killing them and cut the hands and breasts off of at least one of his victims, leading to the media comparing him to the unidentified serial killer Jack the Ripper, who committed at least five murders in the East End of London in the 1880s. He also robbed his victims.

Gao's wife stated that she noticed that her husband would disappear from the house for days at a time; however she never suspected him to be a serial killer. Because he always came home with money, she assumed that he had left to do casual work.
