Could also do a list like that about the Cambodian genocide. This is much smaller though, as most of them are already dead:
Khieu Samphan (born 1931) head of state under Pol Pot, last surviving senior member of the Khmer rouge.
Mam Nai (born 1934) lieutenant of Santebal, Kang Kek Iew's second hand man described as the "most terrifying Khmer Rouge individual"
Chhouk Rin (birth year unknown, around 1953) Khmer Rouge commander charged for killing tourists. In "poor health" in 2004, has/had AIDS, last mentioned in 2011.
