Pen Ran disappeared during the Khmer Rouge genocide of the late 1970s and her exact fate is unknown . Her younger sister Pen Ram said that she survived until the Vietnamese invasion of late 1978/early 1979 when the Khmer Rouge launched their final series of mass executions . Given the goal of the Khmer Rouge to remove foreign influences from Cambodian society , Pen Ran 's individuality probably ensured her death . In a 2015 BBC documentary on the band Cambodian Space Project , who have covered many of Pen Ran 's songs , it was alleged by an interview subject that she was tricked by the Khmer Rouge into performing one of her songs , after which she was led away and executed . Starting in the late 1990s , interest in Pan Ron 's music was revived by the album '' Cambodian Rocks '' and similar CD compilations , while the documentary film '' Do n't Think I 've Forgotten '' described her as one of the most influential artists of her era
