When Aristide, having been elected President, was toppled and forced into exile by the 1991 Haitian coup d'état on September 30, 1991, Izméry founded the KOMEVEB (Komite Mete men pou Verite Blayi) organisation, which attempted to discover and publicise the events surrounding the coup and see the return of democratic government. In 1992, Izméry's brother, Georges, was assassinated by a paramilitary death squad associated with the new regime. Antoine Izméry subsequently lodged a complaint with the Inter-American Commission on Human Rights over the death, which sparked a sharply critical resolution from the commission.
