Guo Zhongmin

Guo Zhongmin (June 24, 1966 - February 23, 2003) was a Chinese mass murderer who killed 13 people in Yangxiaoxiang, Huludao, People's Republic of China on February 18, 2003, before committing suicide.
Due to a land dispute with three neighbours he armed himself with a knife and a stick, entered their homes and stabbed or beat a total of 13 people, all of them fatally, before he fled and hid in the mountains. Searched by more than 1000 police officers Guo eventually committed suicide by swallowing pesticide when he was surrounded on February 23.
