In 22 June 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. 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. He disappeared on 7 October 1979, after last being seen in a Paris nightclub. A popular rumor is that Kim was smuggled back to Seoul and personally shot by President Park in the basement of the Blue House. This version was shown in part 12 of the North Korean film series "Nation and Destiny". His memoirs were published in South Korea in 1985. In February 2005, the "Wolgan Chosun" published claims that Kim had been lured from New Jersey to Paris by a hired female entertainer and then been murdered by a French criminal syndicate in pay of the South Korean government. 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. Three weeks after Kim Hyong-uk's disappearance, Kim Jae-kyu assassinated President Park.
