Cho Sang Kook (Korean: 조상구/趙相九) was a South Korean army captain who killed six people in Hongcheon, South Korea during the night of January 23, 1958.[1][2][3][4][5][6]

Cho, a member of a reconnaissance company, was relieved of his command for his involvement in some sort of finance related scandal. When his request to explain his behaviour was declined he drew a 5mm pistol and began shooting at his colleagues. He first killed his successor captain Hwang Gi-seol, as well as lieutenants Yang Hi-seol and Han Bong-su, who were drinking in a tavern near the base, and then returned to the camp, where he killed Lee Yong-bok, Kim Su-man, and Park Yang-jin. Afterwards the 27-year-old committed suicide.[7]
