Dafroza Gauthier

Dafroza Mukarumongi was born on August 4, 1954, in Astrida, later renamed Butare, in southern Rwanda. She came from a Tutsi pastoralist family. When she was nine, her father was killed during the 1963 massacres in Gikongoro, and she took refuge in the Kibeho church. She later saw her house burned and her elementary school teacher beheaded; she and her mother then lived with relatives in a predominantly female household. She attended secondary school in the Butare region and the lycee de Kigali in the capital. After the 1973 coup and anti-Tutsi pogroms she fled Rwanda with the help of a priest, taking refuge in Burundi near Kirundo and then in Bujumbura, before moving to Belgium in September 1973 to continue her studies with her older brother.

Trained as a chemical engineer, Gauthier settled with her husband Alain in Reims in the early 1980s. After the 1994 genocide destroyed nearly her entire maternal family, she and Alain travelled to Rwanda in 1996 to gather survivors' accounts and began transmitting evidence to lawyers in Paris. She attended the 2001 trial of the Butare Four in Brussels and that November co-founded the Collectif des parties civiles pour le Rwanda (CPCR). The couple filed or supported nearly all of the roughly thirty French complaints against Rwandan nationals suspected of genocide living in France, including cases involving Laurent Bucyibaruta, Felicien Kabuga, Philippe Hategekimana, Aloys Ntiwiragabo, Agathe Habyarimana, Wenceslas Munyeshyaka, Sosthene Munyemana, and Eugene Rwamucyo. They travelled to Rwanda several times a year for testimony. She testified at the 2014 Paris trial of Pascal Simbikangwa, the first such French genocide trial. By her death, seven men had been definitively convicted in French courts through civil-party work associated with the CPCR. She also spoke widely in schools and universities against forgetting and denial.

She married Alain Gauthier in 1977 and obtained French nationality. Alain worked as a French teacher and school principal while she worked as a chemical engineer. They raised three children in Reims and, until 1989, regularly visited Rwanda with their children to see her mother. Their son-in-law is the Franco-Rwandan singer and writer Gael Faye. In February 1994 she cut short an annual trip to Kigali as the genocide began; on April 8, 1994, her mother Suzana Mukamusoni was shot dead in front of the Charles Lwanga church in Nyamirambo. Roughly eighty members of her maternal family were killed that year. She and Alain were sometimes accused by critics of acting as agents of Rwanda's RPF; they rejected those claims and framed their work as justice for victims.

Dafroza Gauthier died of cancer on October 3, 2026, in Reims, France. She was 72. Le Monde reported her death the same day, noting three decades of pursuit of Rwandan genocide suspects who had taken refuge in France and the seven definitive convictions secured in French courts through the couple's civil-party work. She was survived by her husband Alain Gauthier and their family.

With Alain, Gauthier was widely described as among the most persistent civilian hunters of Rwandan genocide suspects on French soil, often compared to Beate and Serge Klarsfeld. The CPCR's dockets and the French trials that followed, from Pascal Simbikangwa onward, form a central part of France's belated judicial reckoning with the Tutsi genocide. She fought genocide denial in classrooms and public forums, welcomed Macron's 2021 recognition of France's role, and in 2017 received Rwanda's National Order of Exceptional Friendship with her husband. A 2023 documentary and comic book, Rwanda, a la poursuite des genocidaires, chronicled their struggle. She is remembered as an engineer who turned private grief into public justice work that outlasted her life.
