As colonel, he took part in the May 16 coup in 1961, when he led a group of soldiers to take Prime Minister John M. Chang into custody. He served for two years as Minister for Home Affairs in the junta and then was director of the KCIA from March 1963 to October 1969, where he was notorious for his brutality and corruption. His nicknames are Flying Pork Cutlet (or Flying Tonkatsu) (날으는 돈가스; Nareuneun Dongaseu), Pork Belly of Fear (공포의 삼겹살; Gongpoui Samgyeopsal),[2] and Namsan Wild Boar (남산 멧돼지; Namsan metdwaeji).[3]
After refusing to support Park's bid for a third term, he was replaced as head of the KCIA by Kim Gye-won. Reportedly, at a meeting with Park, the President asked him, "why don't you take a rest after your long service?"—and on returning to his office, he discovered it had already been cleared out. In 1971, he became a member of the powerless parliament. Kim went into exile in the United States in 1973.[4][5][6][7]
On June 22, 1977, he testified to the Fraser committee about the Koreagate scandal and the activities of Tongsun Park. He also claimed that the Japanese police had had foreknowledge of the kidnapping of Kim Dae-jung.[8] Park had offered him $1 million not to testify, which Kim refused. Kim accepted $500,000 not to publish his memoirs, but reneged on the deal and published them in Japan in April 1979.
Death
He disappeared on October 7, 1979, after last being seen in a casino of Paris, France.[9] A popular rumor is that Kim was smuggled back to Seoul and personally shot by President Park in the basement of the Blue House.[a][10]
In February 2005, the Monthly Chosun published claims that Kim had been lured from New Jersey to Paris by a hired female entertainer and then been kidnapped by a French criminal syndicate in pay of the South Korean government,[11] then murdered and ground up in a hammer mill which is a grinder at a chicken farm and turned into chicken feed by agents of the KCIA.[b][12]
In May 2005, a report from the National Intelligence Service's Truth Commission concluded that Kim had been killed on the orders of Kim Jae-kyu, his successor as director of the KCIA. He was reportedly shot with a silenced pistol and his body was dumped in the woods outside Paris.[9][13]
