Bemeriki was one of the main animatrices[1][5] of Radio Télévision Libre des Mille Collines (RTLM), which played a significant role in promoting the genocide against the Tutsi.

[6] On April 8, 1994, two days after the assassination of Rwandan president Juvénal Habyarimana, Bemeriki ironically noted on air that opposition members of the previous government "could not be found",[7] while several, such as prime minister Agathe Uwilingiyimana had already been murdered.

[9] During the genocide, Bemeriki frequently read out names and addresses of Tutsis alleged to be "RPF accomplices",[10] which led to their murder by Hutu Power paramilitaries such as the Impuzamugambi and Interahamwe.

[14] Bemeriki fled Kigali for her native Zaire in July 1994[2] and was arrested in Minova, near Bukavu in the (by then renamed) Democratic Republic of the Congo on 13 June 1999 by the Rwandan military.

[2][4][5] She was convicted of and pleaded guilty to planning genocide, inciting violence and complicity in several murders and sentenced to life imprisonment by a Gacaca court in 2009.
