On 15 October 1984, Liu was shot to death in the garage of his home in Daly City, California. His killers fled the country, returning to Taiwan. They did not face trial until the U.S. Federal Bureau of Investigation discovered a tape made by chief hitmanChen Chi-li implicating Republic of China military intelligence in the killing, whereupon they began to pressure the government to bring Liu's killers to trial. According to Chen's testimony at his trial in Taipei, Wang Hsi-ling of Kuomintang intelligence ordered the assassination. A month after his conviction, Chen retracted this statement. However, Tung Kuei-sen, another one of the killers, corroborated this at his own trial in the United States in 1988, stating that the order for Liu's death had been given by the Taiwanese government. Tung (who had previously been cleared of racketeering charges related to the assassination) was convicted. The assassination became a major political scandal in Taiwan and American officials were critical of the Kuomintang for allegedly orchestrating an assassination on United States soil.
