Kou Voravong
The political crisis caused by his assassination, barely two months after the Geneva Agreements which prepared to restore peace in Indochina, contributed to bring down the current neutralist government (pro-French) which was replaced by a progressive one (pro-American) in extremely tense atmosphere of the Cold War between Russia and the United States. From 1955 indeed, the political history of this small landlocked country fell trapped inexorably in the ideological confrontation between the capitalist United States and the communist Soviet Union, annihilating any hope of national unification.
Bou Meng
In 2002, he was believed to be dead. In January 2002, Cambodian newspaper Phnom Penh Post wrote that he had died in the 1990s, while Cambodian magazine "Searching for the truth" wrote that he had "disappeared". When Bou Meng found out that people thought that he was dead, he went back to S-21 (which had been converted into a museum).
