On June 26, 1949, Kim was assassinated by Lieutenant Ahn Doo-hee. Ahn burst in and shot him four times while he was at home, reading poetry. Ahn stated that he killed Kim because he saw him as an agent of the Soviet Union. On April 13, 1992, a confession by Ahn was published by Korean newspaper Dongah Ilbo. Kim Il Sung claimed in 1949 that Mr Kim Gu was "murdered by the Syngman Rhee clique". In the confession, Ahn claimed that the assassination had been ordered by Kim Chang-ryong, who served as the head of national security under the Rhee administration. Ahn was murdered by Park Gi-sheo (박기서; 朴琦緖), a follower of Kim's, in 1996. According to Bruce Cumings in his 1981 books, another possible motive for the assassination was Kim's alleged connection to the assassination of Song Jin-woo, a leader of the Korean Democratic Party (KDP) who had chosen to work closely with the American military government. In 2001, declassified documents revealed that Ahn had been working for the U.S. Counter-Intelligence Corps, leading to suggestions of US involvement in the assassination. However, some have questioned the evidence for these accusations.
