However, Kim Chang-Ryong's involvement in the assassination of Kim Gu is not certain; while Kim seems to have looked after Ahn after the assassination, the chief of the operation was Major Chang En-san, the commander of the artillery corps, who himself was arrested by Kim in July 1950 and executed in Daegu. Also, at the time of Kim Gu's death, in 1949, Kim Chang-Ryong was only a subordinate officer and could not possibly have been given such a power as organizing an assassination.
